Discard is usually supported by SSD and thinly provisioned devices as a method for reclaiming unused space. This is no different than trying to reclaim back space which is not used by the file system on the image, but it still occupies space on the host file system. We can do the reclamation on file system which does support hole punching. So when discard request gets to the loop driver we can translate that to punch a hole to the underlying file, hence reclaim the free space. This is very useful for trimming down the size of the image to only what is really used by the file system on that image. Fstrim may be used for that purpose. It has been tested on ext4, xfs and btrfs with the image file systems ext4, ext3, xfs and btrfs. ext4, or ext6 image on ext4 file system has some problems but it seems that ext4 punch hole implementation is somewhat flawed and it is unrelated to this commit. Also this is a very good method of validating file systems punch hole implementation. Note that when encryption is used, discard support is disabled, because using it might leak some information useful for possible attacker.

Whereas spin_unlock_bh can't be called from such contexts. So this patch converts all spin_lock* routines to irqsave variants. Also, spin_lock() used in tasklet is converted to irqsave variants, as tasklet can be interrupted, and dma requests from such interruptions may also call spin_lock.

This patch adds GENHD_FL_NO_PART_SCAN which suppresses partition scan regardless of the number of possible partitions. disk_partitionable() is renamed to disk_part_scan_enabled() as suppressing partition scan doesn't imply the device can't be partitioned using BLKPG_ADD/DEL_PARTITION calls from userland. show_partition() now directly tests disk_max_parts() to maintain backward-compatibility. -v2: Updated to make it clear that only partition scan is suppressed not partitioning itself as suggested by Kay Sievers.

Following is the discussion with ARM Technical Support Guys (David): [Viresh] Manual says: "Bursts do not cross the 1KB address boundary" What does that actually mean? As, Maximum size transferable with a single LLI is 4095 * 4 =16380 ~ 16KB. So, if we don't have src/dest address aligned to burst size, we can't use this big of an LLI. [David] There is a difference between bursts describing the total data transferred by the DMA controller and AHB bursts. Bursts described by the programmable parameters in the PL080 have no direct connection with the bursts that are seen on the AHB bus. The statement that "Bursts do not cross the 1KB address boundary" in the TRM is referring to AHB bursts, where this limitation is a requirement of the AHB spec. You can still issue bursts within the PL080 that are in excess of 1KB. The PL080 will make sure that its bursts are broken down into legal AHB bursts which will be formatted to ensure that no AHB burst crosses a 1KB boundary. Based on above discussion, this patch removes all code related to 1 KB boundary as we are not required to handle this in driver.

Below is summary of mail exchange with them: [Viresh] What is the total data to be transferred in case source and destination bus widths are different. Suppose, source bus width is 2 bytes and destination is 4 bytes. Now in order to transfer 80 bytes, what should be value of TransferSize field in control reg: 40? or 20?. [David from ARM] The value that is programmed into the TransferSize field should be the number of <SourceWidth> transfers needed to achieve the required data transfer. So, to transfer 80 bytes, with a Source Width of 2, the TransferSize field = should be programmed with: Total transfer size ------------------- = 40 <source width> [Viresh] Will this change if source is 4 bytes and dest is 2? [David] Yes - the calculation then becomes: Total transfer size ------------------- =20 <source width> Also, max_bytes_per_lli must be calculated after fixing src and dest widths not before that. So move this code to the correct place. This patch also removes max_bytes_per_lli from earlier print message, as till that point max_bytes_per_lli is unknown.

The generic version of dma_get_required_mask in driver/base/platform.c returns a mask based only on max_pfn. However, this is likely too big for iommu systems and could be too small for platforms that require a dma offset or have a secondary window at a high offset. Override the default, provide a hook in ppc_md used by pseries lpar and cell, and provide the default answer based on memblock_end_of_DRAM(), with hooks for get_dma_offset, and provide an implementation for iommu that looks at the defined table size. Coverting from the end address to the required bit mask is based on the generic implementation. The need for this was discovered when the qla2xxx driver switched to 64 bit dma then reverted to 32 bit when dma_get_required_mask said 32 bits was sufficient.

The ext4_discard_partial_page_buffers routine is a wrapper function to ext4_discard_partial_page_buffers_no_lock. The wrapper function locks the page and passes it to ext4_discard_partial_page_buffers_no_lock. Calling functions that already have the page locked can call ext4_discard_partial_page_buffers_no_lock directly. The ext4_discard_partial_page_buffers_no_lock function zeros a specified range in a page, and unmaps the corresponding buffer heads. Only block aligned regions of the page will have their buffer heads unmapped. Unblock aligned regions will be mapped if needed so that they can be updated with the partial zero out. This function is meant to be used to update a page and its buffer heads to be zeroed and unmapped when the corresponding blocks have been released or will be released. This routine is used in the following scenarios: * A hole is punched and the non page aligned regions of the head and tail of the hole need to be discarded * The file is truncated and the partial page beyond EOF needs to be discarded * The end of a hole is in the same page as EOF. After the page is flushed, the partial page beyond EOF needs to be discarded. * A write operation begins or ends inside a hole and the partial page appearing before or after the write needs to be discarded * A write operation extends EOF and the partial page beyond EOF needs to be discarded This function takes a flag EXT4_DISCARD_PARTIAL_PG_ZERO_UNMAPPED which is used when a write operation begins or ends in a hole. When the EXT4_DISCARD_PARTIAL_PG_ZERO_UNMAPPED flag is used, only buffer heads that are already unmapped will have the corresponding regions of the page zeroed.

This means that if the blocks are smaller than a page, then the block aligned regions of the page inside the hole are left un-zeroed, and their buffer heads are still mapped. This bug is corrected by using ext4_discard_partial_page_buffers to properly zero the partial page at the head and tail of the hole, and unmap the corresponding buffer heads This patch also addresses a bug reported by Lukas while working on a new patch to add discard support for loop devices using punch hole. The bug happened because of the first and last block number needed to be cast to a larger data type before calculating the byte offset, but since now we only need the byte offsets of the pages, we no longer even need to be calculating the byte offsets of the blocks. The code to do the block offset calculations is removed in this patch.

This bug happens because punch hole needs to flush the pages of the hole to avoid race conditions. But if the end of the hole is in the same page as i_size, the buffer heads beyond i_size need to be unmapped and the page needs to be zeroed after it is flushed. To correct this, the new ext4_discard_partial_page_buffers routine is used to zero and unmap the partial page beyond i_size if the end of the hole appears in the same page as i_size. The code has also been optimized to set the end of the hole to the page after i_size if the specified hole exceeds i_size, and the code that flushes the pages has been simplified.

In addition, return an error code. This won't change anything for ocfs2, which will BUG_ON() the non-zero exit code. For ext4, the caller of this function is ext4_handle_dirty_metadata(), and on seeing a non-zero return code, will call __ext4_journal_stop(), which will print the function and line number of the (buggy) calling function and abort the journal. This will allow us to recover instead of bug halting, which is better from a robustness and reliability point of view.

This is necessary to avoid a race which first got introduced in commit 678aaf481, but which was made much more common with the introduction of the "punch hole" functionality. (Especially when dioread_nolock was enabled; when I could reliably reproduce this problem with xfstests #74.) The race is this: If while trying to writeback a delayed allocation inode, there is a need to map delalloc blocks, and we run out of space in the journal, *and* at the same time the inode is already on the committing transaction's t_inode_list (because for example while doing the punch hole operation, ext4_jbd2_file_inode() is called), then the commit operation will wait for the inode to finish all of its pending writebacks by calling filemap_fdatawait(), but since that inode has one or more pages with the PageWriteback flag set, the commit operation will wait forever, and the so the writeback of the inode can never take place, and the kjournald thread and the writeback thread end up waiting for each other --- forever. It's important at this point to recall why an inode is placed on the t_inode_list; it is to provide the data=ordered guarantees that we don't end up exposing stale data. In the case where we are truncating or punching a hole in the inode, there is no possibility that stale data could be exposed in the first place, so we don't need to put the inode on the t_inode_list! The right long-term fix is to get rid of data=ordered mode altogether, and only update the extent tree or indirect blocks after the data has been written. Until then, this change will also avoid some unnecessary waiting in the commit operation.

This bug happens because the truncate routine only zeros the unblock aligned portion of the last page. This means that the block aligned portions of the page appearing after i_size are left unzeroed, and the buffer heads still mapped. This bug is corrected by using ext4_discard_partial_page_buffers in the truncate routine to zero the partial page and unmap the buffer headers.

There are still some places in the ext4 codebase where usage of EXT4_BLOCKS_PER_GROUP needs to be audited/fixed, in code paths that aren't used given the initial restricted assumptions for bigalloc.

That will be up the caller (i.e., truncate), who can figure out whether partial clusters at the beginning or the end of a block range can be freed. We also have to update the ext4_mb_free_metadata() and release_blocks_on_commit() machinery to be cluster-based, since it is used by ext4_free_blocks().

The changes here make sure that arbitrary truncates of sparse files works correctly. Yeah, it's messy. Note that these functions will need to be revisted when the punch ioctl is integrated --- in fact this commit will probably have merge conflicts with the punch changes which Allison Henders and the IBM LTC have been working on. I will need to fix this up when either patch hits mainline.

Since the quota subsystem sets the i_blocks value, this patch fixes the quota accounting and makes sure that the i_blocks value is set correctly.

The race was because we wanted to determine what blocks in a cluster are under delayed allocation and we were using buffer_delayed(bh) check for it. But, the writeback codepath clears this bit without any synchronization which resulted in a race and an ext4 warning similar to: EXT4-fs (ram1): ext4_da_update_reserve_space: ino 13, used 1 with only 0 reserved data blocks The race existed in two places. (1) between ext4_find_delalloc_range() and ext4_map_blocks() when called from writeback code path. (2) between ext4_find_delalloc_range() and ext4_da_get_block_prep() (where buffer_delayed(bh) is set. To fix (1), this patch introduces a new buffer_head state bit - BH_Da_Mapped. This bit is set under the protection of EXT4_I(inode)->i_data_sem when we have actually mapped the delayed allocated blocks during the writeout time. We can now reliably check for this bit inside ext4_find_delalloc_range() to determine whether the reservation for the blocks have already been claimed or not. To fix (2), it was necessary to set buffer_delay(bh) under the protection of i_data_sem. So, I extracted the very beginning of ext4_map_blocks into a new function - ext4_da_map_blocks() - and performed the required setting of bh_delay bit and the quota reservation under the protection of i_data_sem. These two fixes makes the checking of buffer_delay(bh) and buffer_da_mapped(bh) consistent, thus removing the race. Tested: I was able to reproduce the problem by running 'dd' and 'fsync' in parallel. Also, xfstests sometimes used to reproduce this race. After the fix both my test and xfstests were successful and no race (warning message) was observed.

Currently there are two types of DMA driver for Samsung SoCs. The one is S3C-DMA for S3C SoCs and the other is PL330-DMA for S5P SoCs. This patch provides funcion pointers for common DMA operations to DMA client driver like SPI and Audio. It makes DMA client drivers support multi-platform. In addition, this common DMA operations implement the shared actions that are needed for DMA client driver. For example shared actions are filter() function for dma_request_channel() and parameter passing for device_prep_slave_sg().

For example, a system that always has an mmu inline may only require 32 bits while a swiotlb would desire bits to cover all of memory. Therefore add the field if the architecture does not use the generic definition of dma_get_required_mask. The first use will by by powerpc. Note that this does add some dependency on the order in which files are visible here.

This allows the kernel to use huge TLB entries to map pages, which can greatly reduce the number of TLB misses and the amount of TLB thrashing experienced by applications with large memory footprints. Care should be taken when using this on FSL processors, as the number of large TLB entries supported by the core is low (16-64) on current processors. The supported set of hugepage sizes include 4m, 16m, 64m, 256m, and 1g. Page sizes larger than the max zone size are called "gigantic" pages and must be allocated on the command line (and cannot be deallocated). This is currently only fully implemented for Freescale 32-bit BookE processors, but there is some infrastructure in the code for 64-bit BooKE.

However, this is not true if the CPUs are not numbered sequentially. This can happen on a eight-core SOC where cores two and three are removed in the device tree. So instead of blindly looping, we iterate over the discovered CPUs and use the SMP ID as the index. This means that we no longer ask the MPIC how many CPUs there are, so we also delete mpic->num_cpus. We also catch if the number of CPUs in the SOC exceeds the number that the MPIC supports. This should never happen, of course, but it's good to be sure.

Update callers to pass a 64-bit address in r3/r4. Other unused register assignments that were once parameters to machine_init are dropped. For FSL BookE, look up the physical address of the device tree from the effective address passed in r3 by the loader. This is required for situations where memory does not start at zero (due to AMP or IOMMU-less virtualization), and thus the IMA doesn't start at zero, and thus the device tree effective address does not equal the physical address.

The various port_init_hw methods of ppc4xx_pciex_hwops should have been marked __init and when I added ppc4xx_pciex_port_reset_sdr(), which is __init. This added many section mismatch warnings like: WARNING: arch/powerpc/sysdev/built-in.o(.text+0x5c68): Section mismatch in reference from the function ppc440spe_pciex_init_port_hw() to the function .init.text:ppc4xx_pciex_port_reset_sdr() The function ppc440spe_pciex_init_port_hw() references the function __init ppc4xx_pciex_port_reset_sdr(). This is often because ppc440spe_pciex_init_port_hw lacks a __init annotation or the annotation of ppc4xx_pciex_port_reset_sdr is wrong. Trivial patch to silence those warnings.

We pass the current->active_mm as previous mm context to function switch_mmu_context to decrease the context.active by 1. In UP mode, there is no effect.

It turns out SD_WAKE_AFFINE is not set in our node defition. Commit 9fcd18c9e63e (sched: re-tune balancing) enabled SD_WAKE_AFFINE in the node definition for x86 and we need a similar change for ppc64. I used lmbench lat_ctx and perf bench pipe to verify this fix. Each benchmark was run 10 times and the average taken. lmbench lat_ctx: before: 66565 ops/sec after: 204700 ops/sec 3.1x faster perf bench pipe: before: 5.6570 usecs after: 1.3470 usecs 4.2x faster Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> --- arch/powerpc/include/asm/topology.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/powerpc/include/asm/topology.h b/arch/powerpc/include/asm/topology.h index 7ef0d90defc8e..6a7e7251cc029 100644 --- a/arch/powerpc/include/asm/topology.h +++ b/arch/powerpc/include/asm/topology.h @@ -73,7 +73,7 @@ static inline int pcibus_to_node(struct pci_bus *bus) | 1*SD_BALANCE_EXEC \ | 1*SD_BALANCE_FORK \ | 0*SD_BALANCE_WAKE \ - | 0*SD_WAKE_AFFINE \ + | 1*SD_WAKE_AFFINE \ | 0*SD_PREFER_LOCAL \ | 0*SD_SHARE_CPUPOWER \ | 0*SD_POWERSAVINGS_BALANCE \ -- GitLab From 590e4d857153c5d4cf86052cdfd42cf9b0779841 Mon Sep 17 00:00:00 2001 From: Anton Blanchard <anton@samba.org> Date: Sun, 24 Jul 2011 16:33:13 +0000 Subject: [PATCH 0196/1531] sched: Allow SD_NODES_PER_DOMAIN to be overridden We want to override the default value of SD_NODES_PER_DOMAIN on ppc64, so move it into linux/topology.h.

We then use a special hypercall to verify if OPAL is available and if it is, we then trigger a "takeover" which disables pHyp and loads the OPAL runtime firmware, giving control to the kernel in hypervisor mode. This patch add the necessary code to detect that the OPAL takeover capability is present when running under PowerVM (aka pHyp) and perform said takeover to get hypervisor control of the processor. To perform the takeover, we must first use RTAS (within Open Firmware runtime environment) to start all processors & threads, in order to give control to OPAL on all of them. We then call the takeover hypercall on everybody, OPAL will re-enter the kernel main entry point passing it a flat device-tree.

On OPAL v1 we have hvc0 mapped to whatever console the system was configured for (network or hvsi serial port) via the service processor. On OPAL v2 we have hvcN mapped to the Nth console provided by OPAL which generally corresponds to: hvc0 : network console (raw protocol) hvc1 : serial port S1 (hvsi) hvc2 : serial port S2 (hvsi) Note: At this point, early debug console only works with OPAL v1 and shouldn't be enabled in a normal kernel.

Note: gpio-samsung.c includes some SoC dependent codes and it will be replaced next time.

Basically the samsung_xxx prefix is used in gpio-samsung.c instead of s3c_xxx, because unified name can reduce its complexity. Note: some s3c_xxx stil remains because it is used widely. It will be updated next time.

To achieve that, each physical lock must have a system-wide id number that is agreed upon, otherwise remote processors can't possibly assume they're using the same hardware lock. Usually boards have a single hwspinlock device, which provides several hwspinlocks, and in this case, they can be trivially numbered 0 to (num-of-locks - 1). In case boards have several hwspinlocks devices, a different base id should be used for each hwspinlock device (they can't all use 0 as a starting id!). While this is certainly not common, it's just plain wrong to just silently use 0 as a base id whenever the hwspinlock driver is probed. This patch provides a hwspinlock_pdata structure, that boards can use to set a different base id for each of the hwspinlock devices they may have, and demonstrates how to use it with the omap hwspinlock driver. While we're at it, make sure the hwspinlock core prints an explicit error message in case an hwspinlock is registered with an id number that already exists; this will help users catch such base id issues.

Originally hwspinlock core required drivers to register (and later, when needed, unregister) each lock separately. That worked, but required hwspinlocks drivers to do a bit extra work when they were probed/removed. This patch changes hwspin_lock_{un}register() to allow a bank of hwspinlocks to be {un}registered in a single invocation. A new 'struct hwspinlock_device', which contains an array of 'struct hwspinlock's is now being passed to the core upon registration (so instead of wrapping each struct hwspinlock, a priv member has been added to allow drivers to piggyback their private data with each hwspinlock). While at it, several per-lock members were moved to be per-device: 1. struct device *dev 2. struct hwspinlock_ops *ops In addition, now that the array of locks is handled by the core, there's no reason to maintain a per-lock 'int id' member: the id of the lock anyway equals to its index in the bank's array plus the bank's base_id. Remove this per-lock id member too, and instead use a simple pointers arithmetic to derive it. As a result of this change, hwspinlocks drivers are now simpler and smaller (about %20 code reduction) and the memory footprint of the hwspinlock framework is reduced.

Unfortunately this is not the correct config symbol; it should be CONFIG_PPC_MM_SLICES. The result is that attempting to use hugetlbfs on 64-bit Power server processors results in an infinite stack recursion between get_unmapped_area() and hugetlb_get_unmapped_area(). This fixes it by changing the #ifdef to use CONFIG_PPC_MM_SLICES in those functions and also in book3e_hugetlb_preload().

In these cases, xmon invoked by IPI on secondary CPUs will not properly keep quiet, but will print stuff, thereby garbling the primary xmon's output. This patch fixes it, by ignoring the RI bit if the processor does not support it. There's already a version of this for 4xx upstream, which we'll need to extend to other RI-lacking CPUs at some point. For now this adds Book3e processors to the mix.

The only sane thing to do (whether anything in that code can be called remotely sane is debatable) is to special case fpscr and handle it as a separate statement. I initially tried to do it it by making the array access conditional to index < PT_FPSCR and using a 3rd else leg but for some reason gcc was unable to understand it and still spewed the warning. So I ended up with something a tad more intricated but it seems to build on 32-bit and on 64-bit with and without VSX.

The event code 0x180032 should be used to count events on thread 0 and 1. The patch fixes the event code for the L1 cache write. FYI, the documentation lists three event codes for the L1 cache read event and three event codes for the L1 cache write event. The event description for the event codes is as follows: L1 cache read requests 0x80082 LSU 0 only L1 cache read requests 0x8008A LSU 1 only L1 cache read requests 0x80030 LSU 1 or LSU 0, counter 2 only. L1 cache store requests 0x80086 LSU 0 only L1 cache store requests 0x8008E LSU 1 only L1 cache store requests 0x80032 LSU 0 or LSU 1, counter 1 only.

Assume the bdi control line pos_ratio = 1.0 + k * (dirty - bdi_setpoint) where k is the negative slope. If targeting for 12.5% fluctuation range in pos_ratio when dirty pages are fluctuating in range [bdi_setpoint - write_bw/2, bdi_setpoint + write_bw/2], we get slope k = - 1 / (8 * write_bw) Let pos_ratio(x_intercept) = 0, we get the parameter used in code: x_intercept = bdi_setpoint + 8 * write_bw The global/bdi slopes are nicely complementing each other when the system has only one major bdi (indicated by bdi_thresh ~= thresh): 1) slope of global control line => scaling to the control scope size 2) slope of main bdi control line => scaling to the writeout bandwidth so that - in memory tight systems, (1) becomes strong enough to squeeze dirty pages inside the control scope - in large memory systems where the "gravity" of (1) for pulling the dirty pages to setpoint is too weak, (2) can back (1) up and drive dirty pages to bdi_setpoint ~= setpoint reasonably fast. Unfortunately in JBOD setups, the fluctuation range of bdi threshold is related to memory size due to the interferences between disks. In this case, the bdi slope will be weighted sum of write_bw and bdi_thresh. Given equations span = x_intercept - bdi_setpoint k = df/dx = - 1 / span and the extremum values span = bdi_thresh dx = bdi_thresh we get df = - dx / span = - 1.0 That means, when bdi_dirty deviates bdi_thresh up, pos_ratio and hence task ratelimit will fluctuate by -100%. peter: use 3rd order polynomial for the global control line CC: Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: Jan Kara <jack@suse.cz> Signed-off-by: Wu Fengguang <fengguang.wu@intel.com> --- mm/page-writeback.c | 191 +++++++++++++++++++++++++++++++++++++++++++- 1 file changed, 190 insertions(+), 1 deletion(-) diff --git a/mm/page-writeback.c b/mm/page-writeback.c index 0e6dd5c2ed31a..c16ddd8f5cb6b 100644 --- a/mm/page-writeback.c +++ b/mm/page-writeback.c @@ -46,6 +46,8 @@ */ #define BANDWIDTH_INTERVAL max(HZ/5, 1) +#define RATELIMIT_CALC_SHIFT 10 + /* * After a CPU has dirtied this many pages, balance_dirty_pages_ratelimited * will look to see if it needs to force writeback or throttling. @@ -411,6 +413,12 @@ unsigned long determine_dirtyable_memory(void) return x + 1; /* Ensure that we never return 0 */ } +static unsigned long dirty_freerun_ceiling(unsigned long thresh, + unsigned long bg_thresh) +{ + return (thresh + bg_thresh) / 2; +} + static unsigned long hard_dirty_limit(unsigned long thresh) { return max(thresh, global_dirty_limit); @@ -495,6 +503,184 @@ unsigned long bdi_dirty_limit(struct backing_dev_info *bdi, unsigned long dirty) return bdi_dirty; } +/* + * Dirty position control. + * + * (o) global/bdi setpoints + * + * We want the dirty pages be balanced around the global/bdi setpoints. + * When the number of dirty pages is higher/lower than the setpoint, the + * dirty position control ratio (and hence task dirty ratelimit) will be + * decreased/increased to bring the dirty pages back to the setpoint. + * + * pos_ratio = 1 << RATELIMIT_CALC_SHIFT + * + * if (dirty < setpoint) scale up pos_ratio + * if (dirty > setpoint) scale down pos_ratio + * + * if (bdi_dirty < bdi_setpoint) scale up pos_ratio + * if (bdi_dirty > bdi_setpoint) scale down pos_ratio + * + * task_ratelimit = dirty_ratelimit * pos_ratio >> RATELIMIT_CALC_SHIFT + * + * (o) global control line + * + * ^ pos_ratio + * | + * | |<===== global dirty control scope ======>| + * 2.0 .............* + * | .* + * | . * + * | . * + * | . * + * | . * + * | . * + * 1.0 ................................* + * | . . * + * | . . * + * | . . * + * | . . * + * | . . * + * 0 +------------.------------------.----------------------*-------------> + * freerun^ setpoint^ limit^ dirty pages + * + * (o) bdi control line + * + * ^ pos_ratio + * | + * | * + * | * + * | * + * | * + * | * |<=========== span ============>| + * 1.0 .......................* + * | . * + * | . * + * | . * + * | . * + * | . * + * | . * + * | . * + * | . * + * | . * + * | . * + * | . * + * 1/4 ...............................................* * * * * * * * * * * * + * | . . + * | . . + * | . . + * 0 +----------------------.-------------------------------.-------------> + * bdi_setpoint^ x_intercept^ + * + * The bdi control line won't drop below pos_ratio=1/4, so that bdi_dirty can + * be smoothly throttled down to normal if it starts high in situations like + * - start writing to a slow SD card and a fast disk at the same time.

Furthermore we desire fairness in that tasks get throttled proportionally to the amount of pages they dirty. IOW we want to throttle tasks such that we match the dirty rate to the writeout bandwidth, this yields a stable amount of dirty pages: dirty_rate == write_bw (1) The fairness requirement gives us: task_ratelimit = balanced_dirty_ratelimit == write_bw / N (2) where N is the number of dd tasks. We don't know N beforehand, but still can estimate balanced_dirty_ratelimit within 200ms. Start by throttling each dd task at rate task_ratelimit = task_ratelimit_0 (3) (any non-zero initial value is OK) After 200ms, we measured dirty_rate = # of pages dirtied by all dd's / 200ms write_bw = # of pages written to the disk / 200ms For the aggressive dd dirtiers, the equality holds dirty_rate == N * task_rate == N * task_ratelimit_0 (4) Or task_ratelimit_0 == dirty_rate / N (5) Now we conclude that the balanced task ratelimit can be estimated by write_bw balanced_dirty_ratelimit = task_ratelimit_0 * ---------- (6) dirty_rate Because with (4) and (5) we can get the desired equality (1): write_bw balanced_dirty_ratelimit == (dirty_rate / N) * ---------- dirty_rate == write_bw / N Then using the balanced task ratelimit we can compute task pause times like: task_pause = task->nr_dirtied / task_ratelimit task_ratelimit with position control ------------------------------------ However, while the above gives us means of matching the dirty rate to the writeout bandwidth, it at best provides us with a stable dirty page count (assuming a static system). In order to control the dirty page count such that it is high enough to provide performance, but does not exceed the specified limit we need another control. The dirty position control works by extending (2) to task_ratelimit = balanced_dirty_ratelimit * pos_ratio (7) where pos_ratio is a negative feedback function that subjects to 1) f(setpoint) = 1.0 2) df/dx < 0 That is, if the dirty pages are ABOVE the setpoint, we throttle each task a bit more HEAVY than balanced_dirty_ratelimit, so that the dirty pages are created less fast than they are cleaned, thus DROP to the setpoints (and the reverse). Based on (7) and the assumption that both dirty_ratelimit and pos_ratio remains CONSTANT for the past 200ms, we get task_ratelimit_0 = balanced_dirty_ratelimit * pos_ratio (8) Putting (8) into (6), we get the formula used in bdi_update_dirty_ratelimit(): write_bw balanced_dirty_ratelimit *= pos_ratio * ---------- (9) dirty_rate Signed-off-by: Wu Fengguang <fengguang.wu@intel.com> --- include/linux/backing-dev.h | 7 ++++ mm/backing-dev.c | 1 + mm/page-writeback.c | 83 ++++++++++++++++++++++++++++++++++++- 3 files changed, 89 insertions(+), 2 deletions(-) diff --git a/include/linux/backing-dev.h b/include/linux/backing-dev.h index 9ca241a70c490..dff0ff78e8780 100644 --- a/include/linux/backing-dev.h +++ b/include/linux/backing-dev.h @@ -75,10 +75,17 @@ struct backing_dev_info { struct percpu_counter bdi_stat[NR_BDI_STAT_ITEMS]; unsigned long bw_time_stamp; /* last time write bw is updated */ + unsigned long dirtied_stamp; unsigned long written_stamp; /* pages written at bw_time_stamp */ unsigned long write_bandwidth; /* the estimated write bandwidth */ unsigned long avg_write_bandwidth; /* further smoothed write bw */ + /* + * The base dirty throttle rate, re-calculated on every 200ms. + * All the bdi tasks' dirty rate will be curbed under it. + */ + unsigned long dirty_ratelimit; + struct prop_local_percpu completions; int dirty_exceeded; diff --git a/mm/backing-dev.c b/mm/backing-dev.c index fea7e6efd1d7e..ba20f94cde938 100644 --- a/mm/backing-dev.c +++ b/mm/backing-dev.c @@ -686,6 +686,7 @@ int bdi_init(struct backing_dev_info *bdi) bdi->bw_time_stamp = jiffies; bdi->written_stamp = 0; + bdi->dirty_ratelimit = INIT_BW; bdi->write_bandwidth = INIT_BW; bdi->avg_write_bandwidth = INIT_BW; diff --git a/mm/page-writeback.c b/mm/page-writeback.c index 4b954c9fe8469..1721b6523c04f 100644 --- a/mm/page-writeback.c +++ b/mm/page-writeback.c @@ -777,6 +777,79 @@ static void global_update_bandwidth(unsigned long thresh, spin_unlock(&dirty_lock); } +/* + * Maintain bdi->dirty_ratelimit, the base dirty throttle rate. + * + * Normal bdi tasks will be curbed at or below it in long term. + * Obviously it should be around (write_bw / N) when there are N dd tasks. + */ +static void bdi_update_dirty_ratelimit(struct backing_dev_info *bdi, + unsigned long thresh, + unsigned long bg_thresh, + unsigned long dirty, + unsigned long bdi_thresh, + unsigned long bdi_dirty, + unsigned long dirtied, + unsigned long elapsed) +{ + unsigned long write_bw = bdi->avg_write_bandwidth; + unsigned long dirty_ratelimit = bdi->dirty_ratelimit; + unsigned long dirty_rate; + unsigned long task_ratelimit; + unsigned long balanced_dirty_ratelimit; + unsigned long pos_ratio; + + /* + * The dirty rate will match the writeout rate in long term, except + * when dirty pages are truncated by userspace or re-dirtied by FS. + */ + dirty_rate = (dirtied - bdi->dirtied_stamp) * HZ / elapsed; + + pos_ratio = bdi_position_ratio(bdi, thresh, bg_thresh, dirty, + bdi_thresh, bdi_dirty); + /* + * task_ratelimit reflects each dd's dirty rate for the past 200ms. + */ + task_ratelimit = (u64)dirty_ratelimit * + pos_ratio >> RATELIMIT_CALC_SHIFT; + task_ratelimit++; /* it helps rampup dirty_ratelimit from tiny values */ + + /* + * A linear estimation of the "balanced" throttle rate.

It's pretty hard to average out the singular points by increasing the estimation period. Considering that the averaging technique will introduce very undesirable time lags, I give it up totally. (btw, the 3s write_bw averaging time lag is much more acceptable because its impact is one-way and therefore won't lead to oscillations.) The more practical way is filtering -- most singular balanced_dirty_ratelimit points can be filtered out by remembering some prev_balanced_rate and prev_prev_balanced_rate. However the more reliable way is to guard balanced_dirty_ratelimit with task_ratelimit. 2) due to truncates and fs redirties, the (write_bw <=> dirty_rate) match could become unbalanced, which may lead to large systematical errors in balanced_dirty_ratelimit. The truncates, due to its possibly bumpy nature, can hardly be compensated smoothly. So let's face it. When some over-estimated balanced_dirty_ratelimit brings dirty_ratelimit high, dirty pages will go higher than the setpoint. task_ratelimit will in turn become lower than dirty_ratelimit. So if we consider both balanced_dirty_ratelimit and task_ratelimit and update dirty_ratelimit only when they are on the same side of dirty_ratelimit, the systematical errors in balanced_dirty_ratelimit won't be able to bring dirty_ratelimit far away. The balanced_dirty_ratelimit estimation may also be inaccurate near @limit or @freerun, however is less an issue. 3) since we ultimately want to - keep the fluctuations of task ratelimit as small as possible - keep the dirty pages around the setpoint as long time as possible the update policy used for (2) also serves the above goals nicely: if for some reason the dirty pages are high (task_ratelimit < dirty_ratelimit), and dirty_ratelimit is low (dirty_ratelimit < balanced_dirty_ratelimit), there is no point to bring up dirty_ratelimit in a hurry only to hurt both the above two goals. So, we make use of task_ratelimit to limit the update of dirty_ratelimit in two ways: 1) avoid changing dirty rate when it's against the position control target (the adjusted rate will slow down the progress of dirty pages going back to setpoint). 2) limit the step size. task_ratelimit is changing values step by step, leaving a consistent trace comparing to the randomly jumping balanced_dirty_ratelimit. task_ratelimit also has the nice smaller errors in stable state and typically larger errors when there are big errors in rate. So it's a pretty good limiting factor for the step size of dirty_ratelimit. Note that bdi->dirty_ratelimit is always tracking balanced_dirty_ratelimit. task_ratelimit is merely used as a limiting factor.

The main problem of per-task nr_dirtied is, if 1k+ tasks start dirtying pages at exactly the same time, each task will be assigned a large initial nr_dirtied_pause, so that the dirty threshold will be exceeded long before each task reached its nr_dirtied_pause and hence call balance_dirty_pages(). The solution is to watch for the number of pages dirtied on each CPU in between the calls into balance_dirty_pages(). If it exceeds ratelimit_pages (3% dirty threshold), force call balance_dirty_pages() for a chance to set bdi->dirty_exceeded. In normal situations, this safeguarding condition is not expected to trigger at all. On the sqrt in dirty_poll_interval(): It will serve as an initial guess when dirty pages are still in the freerun area. When dirty pages are floating inside the dirty control scope [freerun, limit], a followup patch will use some refined dirty poll interval to get the desired pause time. thresh-dirty (MB) sqrt 1 16 2 22 4 32 8 45 16 64 32 90 64 128 128 181 256 256 512 362 1024 512 The above table means, given 1MB (or 1GB) gap and the dd tasks polling balance_dirty_pages() on every 16 (or 512) pages, the dirty limit won't be exceeded as long as there are less than 16 (or 512) concurrent dd's.

Instead, simply let it idle sleep for some time to throttle the dirtying task. In the mean while, kick off the per-bdi flusher thread to do background writeback IO. RATIONALS ========= - disk seeks on concurrent writeback of multiple inodes (Dave Chinner) If every thread doing writes and being throttled start foreground writeback, it leads to N IO submitters from at least N different inodes at the same time, end up with N different sets of IO being issued with potentially zero locality to each other, resulting in much lower elevator sort/merge efficiency and hence we seek the disk all over the place to service the different sets of IO. OTOH, if there is only one submission thread, it doesn't jump between inodes in the same way when congestion clears - it keeps writing to the same inode, resulting in large related chunks of sequential IOs being issued to the disk. This is more efficient than the above foreground writeback because the elevator works better and the disk seeks less. - lock contention and cache bouncing on concurrent IO submitters (Dave Chinner) With this patchset, the fs_mark benchmark on a 12-drive software RAID0 goes from CPU bound to IO bound, freeing "3-4 CPUs worth of spinlock contention". * "CPU usage has dropped by ~55%", "it certainly appears that most of the CPU time saving comes from the removal of contention on the inode_wb_list_lock" (IMHO at least 10% comes from the reduction of cacheline bouncing, because the new code is able to call much less frequently into balance_dirty_pages() and hence access the global page states) * the user space "App overhead" is reduced by 20%, by avoiding the cacheline pollution by the complex writeback code path * "for a ~5% throughput reduction", "the number of write IOs have dropped by ~25%", and the elapsed time reduced from 41:42.17 to 40:53.23. * On a simple test of 100 dd, it reduces the CPU %system time from 30% to 3%, and improves IO throughput from 38MB/s to 42MB/s. - IO size too small for fast arrays and too large for slow USB sticks The write_chunk used by current balance_dirty_pages() cannot be directly set to some large value (eg. 128MB) for better IO efficiency. Because it could lead to more than 1 second user perceivable stalls. Even the current 4MB write size may be too large for slow USB sticks. The fact that balance_dirty_pages() starts IO on itself couples the IO size to wait time, which makes it hard to do suitable IO size while keeping the wait time under control. Now it's possible to increase writeback chunk size proportional to the disk bandwidth. In a simple test of 50 dd's on XFS, 1-HDD, 3GB ram, the larger writeback size dramatically reduces the seek count to 1/10 (far beyond my expectation) and improves the write throughput by 24%. - long block time in balance_dirty_pages() hurts desktop responsiveness Many of us may have the experience: it often takes a couple of seconds or even long time to stop a heavy writing dd/cp/tar command with Ctrl-C or "kill -9". - IO pipeline broken by bumpy write() progress There are a broad class of "loop {read(buf); write(buf);}" applications whose read() pipeline will be under-utilized or even come to a stop if the write()s have long latencies _or_ don't progress in a constant rate. The current threshold based throttling inherently transfers the large low level IO completion fluctuations to bumpy application write()s, and further deteriorates with increasing number of dirtiers and/or bdi's. For example, when doing 50 dd's + 1 remote rsync to an XFS partition, the rsync progresses very bumpy in legacy kernel, and throughput is improved by 67% by this patchset. (plus the larger write chunk size, it will be 93% speedup). The new rate based throttling can support 1000+ dd's with excellent smoothness, low latency and low overheads. For the above reasons, it's much better to do IO-less and low latency pauses in balance_dirty_pages(). Jan Kara, Dave Chinner and me explored the scheme to let balance_dirty_pages() wait for enough writeback IO completions to safeguard the dirty limit. However it's found to have two problems: - in large NUMA systems, the per-cpu counters may have big accounting errors, leading to big throttle wait time and jitters. - NFS may kill large amount of unstable pages with one single COMMIT. Because NFS server serves COMMIT with expensive fsync() IOs, it is desirable to delay and reduce the number of COMMITs. So it's not likely to optimize away such kind of bursty IO completions, and the resulted large (and tiny) stall times in IO completion based throttling. So here is a pause time oriented approach, which tries to control the pause time in each balance_dirty_pages() invocations, by controlling the number of pages dirtied before calling balance_dirty_pages(), for smooth and efficient dirty throttling: - avoid useless (eg. zero pause time) balance_dirty_pages() calls - avoid too small pause time (less than 4ms, which burns CPU power) - avoid too large pause time (more than 200ms, which hurts responsiveness) - avoid big fluctuations of pause times It can control pause times at will. The default policy (in a followup patch) will be to do ~10ms pauses in 1-dd case, and increase to ~100ms in 1000-dd case. BEHAVIOR CHANGE =============== (1) dirty threshold Users will notice that the applications will get throttled once crossing the global (background + dirty)/2=15% threshold, and then balanced around 17.5%. Before patch, the behavior is to just throttle it at 20% dirtyable memory in 1-dd case. Since the task will be soft throttled earlier than before, it may be perceived by end users as performance "slow down" if his application happens to dirty more than 15% dirtyable memory. (2) smoothness/responsiveness Users will notice a more responsive system during heavy writeback. "killall dd" will take effect instantly.

The best test case for this code is to run 100 "dd bs=4M" tasks on btrfs and check its pause time distribution.

Also gently increase a small bdi_thresh to avoid it stuck in 0 for some light dirtied bdi. It's particularly useful for JBOD and small memory system. It may result in (pos_ratio > 1) at the setpoint and push the dirty pages high. This is more or less intended because the bdi is in the danger of IO queue underflow.

Tracing shows find that in single disk case, bdi_writeback is always kept high while in JBOD case, it could drop low from time to time and correspondingly bdi_reclaimable could sometimes rush high. The fix is to watch bdi_reclaimable and kick background writeback as soon as it goes high. This resembles the global background threshold but in per-bdi manner. The trick is, as long as bdi_reclaimable does not go high, bdi_writeback naturally won't go low because bdi_reclaimable+bdi_writeback ~= bdi_thresh. With less fluctuated writeback pages, JBOD performance is observed to increase noticeably in various cases. vmstat:nr_written values before/after patch: 3.1.0-rc4-wo-underrun+ 3.1.0-rc4-bgthresh3+ ------------------------ ------------------------ 125596480 +25.9% 158179363 JBOD-10HDD-16G/ext4-100dd-1M-24p-16384M-20:10-X 61790815 +110.4% 130032231 JBOD-10HDD-16G/ext4-10dd-1M-24p-16384M-20:10-X 58853546 -0.1% 58823828 JBOD-10HDD-16G/ext4-1dd-1M-24p-16384M-20:10-X 110159811 +24.7% 137355377 JBOD-10HDD-16G/xfs-100dd-1M-24p-16384M-20:10-X 69544762 +10.8% 77080047 JBOD-10HDD-16G/xfs-10dd-1M-24p-16384M-20:10-X 50644862 +0.5% 50890006 JBOD-10HDD-16G/xfs-1dd-1M-24p-16384M-20:10-X 42677090 +28.0% 54643527 JBOD-10HDD-thresh=100M/ext4-100dd-1M-24p-16384M-100M:10-X 47491324 +13.3% 53785605 JBOD-10HDD-thresh=100M/ext4-10dd-1M-24p-16384M-100M:10-X 52548986 +0.9% 53001031 JBOD-10HDD-thresh=100M/ext4-1dd-1M-24p-16384M-100M:10-X 26783091 +36.8% 36650248 JBOD-10HDD-thresh=100M/xfs-100dd-1M-24p-16384M-100M:10-X 35526347 +14.0% 40492312 JBOD-10HDD-thresh=100M/xfs-10dd-1M-24p-16384M-100M:10-X 44670723 -1.1% 44177606 JBOD-10HDD-thresh=100M/xfs-1dd-1M-24p-16384M-100M:10-X 127996037 +22.4% 156719990 JBOD-10HDD-thresh=2G/ext4-100dd-1M-24p-16384M-2048M:10-X 57518856 +3.8% 59677625 JBOD-10HDD-thresh=2G/ext4-10dd-1M-24p-16384M-2048M:10-X 51919909 +12.2% 58269894 JBOD-10HDD-thresh=2G/ext4-1dd-1M-24p-16384M-2048M:10-X 86410514 +79.0% 154660433 JBOD-10HDD-thresh=2G/xfs-100dd-1M-24p-16384M-2048M:10-X 40132519 +38.6% 55617893 JBOD-10HDD-thresh=2G/xfs-10dd-1M-24p-16384M-2048M:10-X 48423248 +7.5% 52042927 JBOD-10HDD-thresh=2G/xfs-1dd-1M-24p-16384M-2048M:10-X 206041046 +44.1% 296846536 JBOD-10HDD-thresh=4G/xfs-100dd-1M-24p-16384M-4096M:10-X 72312903 -19.4% 58272885 JBOD-10HDD-thresh=4G/xfs-10dd-1M-24p-16384M-4096M:10-X 50635672 -0.5% 50384787 JBOD-10HDD-thresh=4G/xfs-1dd-1M-24p-16384M-4096M:10-X 68308534 +115.7% 147324758 JBOD-10HDD-thresh=800M/ext4-100dd-1M-24p-16384M-800M:10-X 57882933 +14.5% 66269621 JBOD-10HDD-thresh=800M/ext4-10dd-1M-24p-16384M-800M:10-X 52183472 +12.8% 58855181 JBOD-10HDD-thresh=800M/ext4-1dd-1M-24p-16384M-800M:10-X 53788956 +94.2% 104460352 JBOD-10HDD-thresh=800M/xfs-100dd-1M-24p-16384M-800M:10-X 44493342 +35.5% 60298210 JBOD-10HDD-thresh=800M/xfs-10dd-1M-24p-16384M-800M:10-X 42641209 +18.9% 50681038 JBOD-10HDD-thresh=800M/xfs-1dd-1M-24p-16384M-800M:10-X Signed-off-by: Wu Fengguang <fengguang.wu@intel.com> --- fs/fs-writeback.c | 17 ++++++++++++----- 1 file changed, 12 insertions(+), 5 deletions(-) diff --git a/fs/fs-writeback.c b/fs/fs-writeback.c index 28076562ada0d..6401cd76f109e 100644 --- a/fs/fs-writeback.c +++ b/fs/fs-writeback.c @@ -658,14 +658,21 @@ long writeback_inodes_wb(struct bdi_writeback *wb, long nr_pages) return nr_pages - work.nr_pages; } -static inline bool over_bground_thresh(void) +static bool over_bground_thresh(struct backing_dev_info *bdi) { unsigned long background_thresh, dirty_thresh; global_dirty_limits(&background_thresh, &dirty_thresh); - return (global_page_state(NR_FILE_DIRTY) + - global_page_state(NR_UNSTABLE_NFS) > background_thresh); + if (global_page_state(NR_FILE_DIRTY) + + global_page_state(NR_UNSTABLE_NFS) > background_thresh) + return true; + + if (bdi_stat(bdi, BDI_RECLAIMABLE) > + bdi_dirty_limit(bdi, background_thresh)) + return true; + + return false; } /* @@ -727,7 +734,7 @@ static long wb_writeback(struct bdi_writeback *wb, * For background writeout, stop when we are below the * background dirty threshold */ - if (work->for_background && !over_bground_thresh()) + if (work->for_background && !over_bground_thresh(wb->bdi)) break; if (work->for_kupdate) { @@ -811,7 +818,7 @@ static unsigned long get_nr_dirty_pages(void) static long wb_check_background_flush(struct bdi_writeback *wb) { - if (over_bground_thresh()) { + if (over_bground_thresh(wb->bdi)) { struct wb_writeback_work work = { .nr_pages = LONG_MAX, -- GitLab From 6e01280f34be02e5e7635debb045aab3705bb5bf Mon Sep 17 00:00:00 2001 From: Inderpal Singh <inderpal.singh@linaro.org> Date: Mon, 3 Oct 2011 08:51:20 +0900 Subject: [PATCH 0286/1531] ARM: EXYNOS4: Configure MAX8997 PMIC for ORIGEN Configure MAX8997 PMIC and provide platform specific data for ORIGEN board.

Samsung DMA driver has had a TODO in the hw_free() function wondering if we need to flush the DMA buffers. Up until now the answer has been no but with the recent improvements Boojin has done to the DMA infrastructure for the Samsung port the answer has changed to yes for at least S3C6410 systems. If we don't then when we next prepare() the channel the API will get confused trying to run callbacks on the transfers hanging around from the previous time the stream was open and oops.

dc98e4145d82e471cc02d4e0b950a1945bcb084f Mon Sep 17 00:00:00 2001 From: Kukjin Kim <kgene.kim@samsung.com> Date: Wed, 28 Sep 2011 20:48:52 +0900 Subject: [PATCH 0324/1531] ARM: SAMSUNG: Move S3C24XX header files to plat-samsung This patch moves header files from plat-s3c24xx to plat-samsung to remove plat-s3c24xx directory to make one plat-samsung directory for Samsung SoCs. And this patch includes fixing coding style, too.

So this patch adds all the error patch for ext4_mb_init. And all the pointers are reset to NULL in case the caller may double free them.

The single entry is important because when we bring up secondary cores they need to ensure any data structure they need to access (eg PACA or stack) is always mapped. So we really need to determine what size will actually be mapped by the first TLB entry to ensure we limit early memory references to that region. We refactor the map_mem_in_cams() code to provider a helper function that we can utilize to determine the size of the first TLB entry while taking into account size and alignment constraints.

There are different kinds of FPGAs used on the boards, but only two are currently standard: "pixis", "ngpixis", and "qixis". Although there are minor differences among the boards that have one kind of FPGA, most of the functionality is the same, so it makes sense to create common compatibility strings. We also need to update the P1022DS platform file, because the compatible string for its PIXIS node has changed. This means that older kernels are not compatible with newer device trees. This is not a real problem, however, since that particular function doesn't work anyway. When the DIU is active, the PIXIS is in "indirect mode", and so cannot be accessed as a memory-mapped device.

Guard against issuing BLKIF_OP_WRITE_BARRIER or BLKIF_OP_FLUSH_CACHE by checking whether we successfully negotiated with the backend. The negotiation with the backend also sets the q->flush_flags which fortunately for us is also used when submitting an bio to us. If we don't support barriers or flushes it would be set to zero so we should never end up having to deal with REQ_FLUSH | REQ_FUA. However, other third party implementations of __make_request that might be stacked on top of us might not be so smart, so lets fix this up.

The 'operation' parameters are the ones provided to the bio layer while the req->operation are the ones passed in between the backend and frontend. We used the wrong 'operation' value to squash the call to map pages when processing the discard operation resulting in an hypercall that did nothing. Lets guard against going in the mapping function by checking for the proper operation type.

Where the logical is 0..5, the hard id goes 0,1,4..7. This can causes issues for places we utilize PIR to index into array like in debug exception handlers for finding the exception stack. Move to setting up PIR with hard_smp_processor_id fixes the issue.

However, each subwindow has to have the same alignment, which +means they cannot be located at just any address. Because of these +restrictions, it is usually impossible to create a 4KB subwindow that +covers MSIIR where it's normally located. + +Therefore, the hypervisor has to create a subwindow inside the same +primary window used for memory, but mapped to the MSIR block (where MSIIR +lives). The first subwindow after the end of guest memory is used for +this. The address specified in the msi-address-64 property is the PCI +address of MSIIR.

This is a fairly nasty shortcut as write_begin and write_end are only callbacks for the generic write code and expect to be called with filesystem specific locks held. This code currently causes various issues for clustered filesystems as it doesn't take the required cluster locks, and it also causes issues for XFS as it doesn't properly lock against the swapext ioctl as called by the defragmentation tools. This in case causes data corruption if defragmentation hits a busy loop device in the wrong time window, as reported by RH QA. The reason why we have this shortcut is that it saves a data copy when doing a transformation on the loop device, which is the technical term for using cryptoloop (or an XOR transformation). Given that cryptoloop has been deprecated in favour of dm-crypt my opinion is that we should simply drop this shortcut instead of finding complicated ways to to introduce a formal interface for this shortcut.

This was failing for S3C64xx SoCs as in order to support identification of the exact device the mask covers both variants of the chip, meaning that the test would always fail on S3C6410 devices.

Unfortunately, on a BE system such as ppc64, this comparison becomes: if (cpu_to_le32(new_seq) != le32_to_cpu(cpu_to_le32(new_seq)) { /* fail the mount */ Except for a few palindromic sequence numbers, this test always causes the mount to fail, which makes MMP filesystems generally unmountable on ppc64.

If a SCSI device is removed while the device is still open, the sdev puts the base reference to the queue on release. When the bdev is finally released, the associated queue is already gone along with the bdi and bdev_inode_switch_bdi() ends up dereferencing already freed bdi. Even if it were not for this bug, disk not holding onto the associated queue is very unusual and error-prone. Fix it by making add_disk() take an extra reference to its queue and put it on disk_release() and ensuring that disk and its fops owner are put in that order after all accesses to the disk and queue are complete.

This is fundamentally broken. The queue owner (e.g. SCSI layer) doesn't have a way to know whether there are other active users before calling blk_cleanup_queue() and other users (e.g. bsg) don't have any guarantee that the queue is and would stay valid while it's holding a reference. With delay added in blk_queue_bio() before queue_lock is grabbed, the following oops can be easily triggered when a device is removed with in-flight IOs. sd 0:0:1:0: [sdb] Stopping disk ata1.01: disabled general protection fault: 0000 [#1] PREEMPT SMP CPU 2 Modules linked in: Pid: 648, comm: test_rawio Not tainted 3.1.0-rc3-work+ #56 Bochs Bochs RIP: 0010:[<ffffffff8137d651>] [<ffffffff8137d651>] elv_rqhash_find+0x61/0x100 ...

Depending on timing, it either oopses or throttled bios are lost putting tasks which are waiting for bio completion into eternal D state. The way it should work is having the usual clear distinction between shutdown and release. Shutdown drains all currently pending requests, marks the queue dead, and performs partial teardown of the now unnecessary part of the queue. Even after shutdown is complete, reference holders are still allowed to issue requests to the queue although they will be immmediately failed. The rest of teardown happens on release. This patch makes the following changes to make blk_queue_cleanup() behave as proper shutdown. * QUEUE_FLAG_DEAD is now set while holding both q->exit_mutex and queue_lock. * Unsynchronized DEAD check in generic_make_request_checks() removed. This couldn't make any meaningful difference as the queue could die after the check. * blk_drain_queue() updated such that it can drain all requests and is now called during cleanup. * blk_throtl updated such that it checks DEAD on grabbing queue_lock, drains all throttled bios during cleanup and free td when queue is released.

Turns out this patch is producing many build errors with gcc 4.2. Based on further testing with a test case extracted from the build errors found further build errors and suboptimal generation even in violation of the "R" constraint. To make matters worse, the binutils changes also don't work quite as intended so revert this patch for now. --- arch/mips/include/asm/io.h | 12 ++---------- arch/mips/pmc-sierra/yosemite/py-console.c | 12 ++---------- 2 files changed, 4 insertions(+), 20 deletions(-) diff --git a/arch/mips/include/asm/io.h b/arch/mips/include/asm/io.h index b04e4de5dd2e0..a58f22998a865 100644 --- a/arch/mips/include/asm/io.h +++ b/arch/mips/include/asm/io.h @@ -329,14 +329,10 @@ static inline void pfx##write##bwlq(type val, \ "dsrl32 %L0, %L0, 0" "\n\t" \ "dsll32 %M0, %M0, 0" "\n\t" \ "or %L0, %L0, %M0" "\n\t" \ - ".set push" "\n\t" \ - ".set noreorder" "\n\t" \ - ".set nomacro" "\n\t" \ "sd %L0, %2" "\n\t" \ - ".set pop" "\n\t" \ ".set mips0" "\n" \ : "=r" (__tmp) \ - : "0" (__val), "R" (*__mem)); \ + : "0" (__val), "m" (*__mem)); \ if (irq) \ local_irq_restore(__flags); \ } else \ @@ -359,16 +355,12 @@ static inline type pfx##read##bwlq(const volatile void __iomem *mem) \ local_irq_save(__flags); \ __asm__ __volatile__( \ ".set mips3" "\t\t# __readq" "\n\t" \ - ".set push" "\n\t" \ - ".set noreorder" "\n\t" \ - ".set nomacro" "\n\t" \ "ld %L0, %1" "\n\t" \ - ".set pop" "\n\t" \ "dsra32 %M0, %L0, 0" "\n\t" \ "sll %L0, %L0, 0" "\n\t" \ ".set mips0" "\n" \ : "=r" (__val) \ - : "R" (*__mem)); \ + : "m" (*__mem)); \ if (irq) \ local_irq_restore(__flags); \ } else { \ diff --git a/arch/mips/pmc-sierra/yosemite/py-console.c b/arch/mips/pmc-sierra/yosemite/py-console.c index 434d7b1a8c6a7..b7f1d9c4a8a3c 100644 --- a/arch/mips/pmc-sierra/yosemite/py-console.c +++ b/arch/mips/pmc-sierra/yosemite/py-console.c @@ -65,15 +65,11 @@ static unsigned char readb_outer_space(unsigned long long phys) __asm__ __volatile__ ( " .set mips3 \n" - " .set push \n" - " .set noreorder \n" - " .set nomacro \n" " ld %0, %1 \n" - " .set pop \n" " lbu %0, (%0) \n" " .set mips0 \n" : "=r" (res) - : "R" (vaddr)); + : "m" (vaddr)); write_c0_status(sr); ssnop_4(); @@ -93,15 +89,11 @@ static void writeb_outer_space(unsigned long long phys, unsigned char c) __asm__ __volatile__ ( " .set mips3 \n" - " .set push \n" - " .set noreorder \n" - " .set nomacro \n" " ld %0, %1 \n" - " .set pop \n" " sb %2, (%0) \n" " .set mips0 \n" : "=&r" (tmp) - : "R" (vaddr), "r" (c)); + : "m" (vaddr), "r" (c)); write_c0_status(sr); ssnop_4(); -- GitLab From a74e33535fa27c758d2a23ebf5f8964bf19940bc Mon Sep 17 00:00:00 2001 From: Jayachandran C <jayachandranc@netlogicmicro.com> Date: Wed, 22 Jun 2011 01:37:05 +0530 Subject: [PATCH 0450/1531] MIPS:Netlogic:Fix section mismatch warnings.

The MFD_SUPPORT is actually not required at all, it only hides the submenu when not set, with the effect that Kconfig warns about missing dependencies when another driver selects an MFD driver while MFD_SUPPORT is disabled. Turning the MFD submenu back from menuconfig into a plain menu simplifies the Kconfig syntax for those kinds of users and avoids the surprise when the menu suddenly appears because another driver was enabled that selects this symbol.

In the ideal world we wouldn't need this and we could avoid any init dependancies of this form, but in practice we can't do it for some cases.

GitLab From 8959e74399c798b45c0f5d477972b927c28f8dc9 Mon Sep 17 00:00:00 2001 From: Linus Walleij <linus.walleij@linaro.org> Date: Mon, 26 Sep 2011 11:45:30 +0200 Subject: [PATCH 0515/1531] mfd: Delete ab3550 driver The AB3550 never passed the prototype stage. Instead it was used as a precursor to AB5500 for testing basic building blocks used in that chip, since they had large similarities. Since AB3550 will not see the light of day in product form and since the prototypes are no longer used, let's delete the driver and any references to it.

Although the irq_desc and lock are different, LOCKDEP treats these as equivalent, presumably due to problems that can be incurred when locking more than one irq_desc, so best to avoid this. Suspend/resume actions implemented as PM notifiers to avoid touch the TWL core for this.

We delete the parts of db8500-prcmu.h that is now PRCMU-neutral, and calls will be diverted to respective driver. Common registers are in dbx500-prcmu-regs.h and common accessors and defines in <linux/mfd/dbx500-prcmu.h> This way we get a a lot more abstraction and code reuse.

And Jens replied with "We can kill bio_set_completion_cpu(). I'm fine with leaving cpu control to the request based drivers, they are the only ones that can toggle the setting anyway". So this patch tries to remove all the work of controling complete cpu from a bio.

It turns out that an empty flush request can be sent into blk_insert_flush. When the BUG_ON was fixed to allow for this, I/O on the underlying device would stall. The reason is that blk_insert_cloned_request does not kick the queue. In the aforementioned commit, I had added a special case to kick the queue if data was sent down but the queue flags did not require a flush. A better solution is to push the queue kick up into blk_insert_cloned_request. This patch, along with a follow-on which fixes the BUG_ON, fixes the issue reported.

If a SCSI device is removed while the device is still open, the sdev puts the base reference to the queue on release. When the bdev is finally released, the associated queue is already gone along with the bdi and bdev_inode_switch_bdi() ends up dereferencing already freed bdi. Even if it were not for this bug, disk not holding onto the associated queue is very unusual and error-prone. Fix it by making add_disk() take an extra reference to its queue and put it on disk_release() and ensuring that disk and its fops owner are put in that order after all accesses to the disk and queue are complete.

Now perf_event.c contains only the callchain support, everything else is in perf_event_mipsxx.c There are no code changes, only moving of functions from one file to the other, or removing empty unneeded functions.

The hard coded constants are moved to struct mips_pmu. All counter register access move to the read_counter and write_counter function pointers, which are set to either 32-bit or 64-bit access methods at initialization time. Many of the function pointers in struct mips_pmu were not needed as there was only a single implementation, these were removed. I couldn't figure out what made struct cpu_hw_events.msbs[] at all useful, so I removed it too. Some functions and other declarations were reordered to reduce the need for forward declarations.

The sunrpc layer keeps a cache of recently used credentials and 'unx_match' is used to find the credential which matches the current process. However unx_match allows a match when the cached credential has extra groups at the end of uc_gids list which are not in the process group list. So if a process with a list of (say) 4 group accesses a file and gains access because of the last group in the list, then another process with the same uid and gid, and a gid list being the first tree of the gids of the original process tries to access the file, it will be granted access even though it shouldn't as the wrong rpc credential will be used.

For such services we will create rpcbind clients and remove all stale portmap registrations. Also, svc_rpcb_cleanup() will be set as sv_shutdown callback for such services in case of this field wasn't initialized earlier. This will allow to destroy rpcbind clients when no other users of them left. Note: Currently, any creating service will be detected as portmap user. Probably, this is wrong.

Every sram bank will register its own platform device info, after the sram allocator create the generic pool for the sram bank, the user module can use the pool's name to get the pool handler; then it can use the handler to alloc/free memory with genalloc APIs.

It does this by allocating a 64-byte stack buffer, calling d_path() to grab the mount point through which this file was accessed, and then memcpy()ing 64 bytes into the superblock's s_last_mounted field, starting from the return value of d_path(), which is stored as "cp". However, if cp > buf (which it frequently is since path components are prepended starting at the end of buf) then we can end up copying stack data into the superblock. Writing stack variables into the superblock doesn't sound like a great idea, so use strlcpy instead. Andi Kleen suggested using strlcpy instead of strncpy. Signed-off-by: Darrick J.

Subsequently, if any subdirectories are deleted, ext4_dec_count() decrements the i_nlink count, which may go to 0 temporarily before being incremented back to 1. While this is done under i_mutex, which prevents races for directory and inode operations that check i_nlink, the temporary i_nlink == 0 case is exposed to userspace via stat() and similar calls that do not hold i_mutex. Instead, change the code to not decrement i_nlink count for any directories that do not already have i_nlink larger than 2.

One of the lessons learned from Adaptive Powersaver is that voltage values returned by processor are for worst case scenario. But required voltage is changing with CPU temperature. And even processors produced in the same batch can have different minimum voltage necessary for stable work at specified frequency. On Elonex Webbook, once system starts, temperature never drops below 48 deg. C. Loading module after systems start allows user to lower CPU voltage and still have stable system. Sadly C7 doesn't allow code to set frequency or voltage from outside limits. If you ask it to set voltage lower then minimum it will ignore you. Thats why it isn't possible to change minimum voltage for minimum frequency too. Changing maximum voltage on Elonex Webbook leads to very good results. Looks like VIA C7 1.6GHz 1084mV can safetly run at 892mV. This means 83% of orginal value. If same percentage applies to power generated it means 12.5W in the place of 15W. Not much, but it is better then nothing. Only C7-M makes it possible. If voltage is too low by 16mV or more you will experience kernel panic. If voltage is too low by 32mV or more you will experience system freeze.

Some of they set the ARM core frequency at boot time even when the boot is a resume from suspend-to-RAM. Such changes may create inconsistency in the data of CPUFREQ driver and have incurred hang issues with suspend-to-RAM. This patch enables to save and restore CPU frequencies with pm-notifier and sets the frequency at the initial (boot-time) value so that there wouldn't be any inconsistency between bootloader and kernel. This patch does not use CPUFREQ's suspend/resume callbacks because they are syscore-ops, which do not allow to use mutex that is being used by regulators that are used by the target function. This also prevents any CPUFREQ transitions during suspend-resume context, which could be dangerous at noirq-context along with regulator framework.

Doing so removes the expensive invocations of memmove() which occur during extent insertion and the subsequent merge. In practice this should be the common case for clients performing append writes into files pre-allocated via fallocate(FALLOC_FL_KEEP_SIZE). In such a workload performed via direct IO and when using a suboptimal implementation of memmove() (x86_64 prior to the 2.6.39 rewrite), this patch reduces kernel CPU consumption by 32%. Two new trace points are added to ext4_ext_convert_to_initialized() to offer visibility into its operations. No exit trace point has been added due to the multiplicity of return points. This can be revisited once the upstream cleanup is backported.

EXT_LAST_INDEX()) instead to only move existing entries. The code flow is also simplified slightly to highlight similarities and reduce code duplication in the insertion logic. This patch reduces system CPU consumption by over 25% on a 4kB synchronous append DIO write workload when used with the pre-2.6.39 x86_64 memmove() implementation. With the much faster 2.6.39 memmove() implementation we still see a decrease in system CPU usage between 2% and 7%. Note that the ext_debug() output changes with this patch, splitting some log information between entries. Users of the ext_debug() output should note that the "move %d" units changed from reporting the number of bytes moved to reporting the number of entries moved.

It was using global PID for reaching policy configuration of the process. However, use of PID returns stale policy configuration when the process's subjective credentials and objective credentials differ.

I managed to reproduce this with a very hacked-up "streamtest" binary from the Ceph tree. Ceph is doing a lot of xattr writes, to out-of-inode blocks. There is also another thread which does sync_file_range and close, of the same files. The problem appears to happen due to this race: sync/flush thread xattr-set thread ----------------- ---------------- do_writepages ext4_xattr_set ext4_da_writepages ext4_xattr_set_handle mpage_da_map_blocks ext4_xattr_block_set set DELALLOC_RESERVE ext4_new_meta_blocks ext4_mb_new_blocks if (!i_delalloc_reserved_flag) vfs_dq_alloc_block ext4_get_blocks down_write(i_data_sem) set i_delalloc_reserved_flag ... up_write(i_data_sem) if (i_delalloc_reserved_flag) vfs_dq_alloc_block_nofail In other words, the sync/flush thread pops in and sets i_delalloc_reserved_flag on the inode, which makes the xattr thread think that it's in a delalloc path in ext4_new_meta_blocks(), and add the block for a second time, after already having added it once in the !i_delalloc_reserved_flag case in ext4_mb_new_blocks The real problem is that we shouldn't be using the DELALLOC_RESERVED state flag, and instead we should be passing EXT4_GET_BLOCKS_DELALLOC_RESERVE down to ext4_map_blocks() instead of using an inode state flag. We'll fix this for now with using i_data_sem to prevent this race, but this is really not the right way to fix things.

Modify cifs to assume that the supplied password is encoded according to iocharset. Before this patch passwords would be treated as raw 8-bit data, which made authentication with Unicode passwords impossible (at least passwords with characters > 0xFF). The previous code would as a side effect accept passwords encoded with ISO 8859-1, since Unicode < 0x100 basically is ISO 8859-1. Software which relies on that will no longer support password chars > 0x7F unless it also uses iocharset=iso8859-1. (mount.cifs does not care about the encoding so it will work as expected.)

(1)Asynchronous SCSI scanning: This will allow the drivers to scan for devices in parallel while other device drivers are loading at the same time. This will improve the amount of time it takes for the OS to load. (2) Reporting Devices while port enable is active: This feature will allow devices to be reported to OS immediately while port enable is active. The previous implementation waits for port enable to complete, and then report devices. This feature is only enabled on IT firmware configurations when there are no boot device configured in BIOS Configuration Utility, else the driver will wait till port enable completes reporting devices. For IR firmware, this feature is turned off. This feature is to address large SAS topologies (>100 drives) when the boot OS is using onboard SATA device, in other words, the boot devices is not connected to our controller. (3) Scanning for devices after diagnostic reset completes: A new routine _scsih_scan_start is added. This will scan the expander pages, IR pages, and sas device pages, then reporting new devices to SCSI Mid layer. It seems the driver is not supporting adding devices while diagnostic reset is active. Apparently this is due to the sanity checks on ioc->shost_recovery flag throughout the context of kernel work thread FIFO, and the mpt2sas_fw_work.

In order to get info on inactive volumes, the driver needs to change the action to MPI2_RAID_PGAD_FORM_GET_NEXT_CONFIGNUM, and traverse each config till the iocstatus is MPI2_IOCSTATUS_CONFIG_INVALID_PAGE returned. Added a change in the driver to remove the instance of sas_device object when the driver returns "1" from the slave_configure callback. Also fixed code to report the hot spares to the operating system with a /dev/sg assigned.

A 'wb_reason' enumeration has been added to writeback.h, to enumerate the possible reasons. The 'writeback_work_class' and tracepoint event class and 'writeback_queue_io' tracepoints are updated to include the symbolic 'reason' in all trace events. And the 'writeback_inodes_sbXXX' family of routines has had a wb_stats parameter added to them, so callers can specify why writeback is being started.

Also, prior to that conversion we borrowed the mvsas MVS_DEV_EH approach to prevent the unwanted extra ap->ops->phy_reset(ap) that occurred in the ata_bus_probe() path. After the conversion to new libata eh resets at discovery are more frequent and get filtered prematurely by IDEV_EH. The result is that our bcn filtering has been blocked from running and at discovery and it appears to stall discovery completion to the point of triggering hung task timeouts. So, revert the implementation for now. When it returns it will go into libsas proper. The domain rediscovery that takes place due to ->lldd_I_T_nexus_reset() events should now be properly waited for by the ata_port_wait_eh() call in ata_port_probe(). So the hard coded delay in the isci ->lldd_I_T_nexus_reset() and other libsas drivers should help debounce the libsas thread from seeing temporary device removals.

Developed and tested on OCZ RevoDrive3 120GB [PCI 1b85:1021] Should work on: - OCZ RevoDrive3 (2x SandForce 2281) - OCZ RevoDrive3 X2 (4x SandForce 2281) - OCZ zDrive R4 CM84 (4x SandForce 2281) - OCZ zDrive R4 CM88 (8x SandForce 2281) - OCZ zDrive R4 RM84 (4x SandForce 2582) - OCZ zDrive R4 RM88 (8x SandForce 2582) All of this because a friend recently bought a OCZ RevoDrive3 and was bitten by the lack of Linux support. Notes from testing: ------------------- - SMART works. - VPD Device Identification is "OCZ-REVODRIVE3" - Thin provisioning/TRIM seems to be implemented as WRITE SAME UNMAP, with deterministic (non-zero) read after TRIM, but I'm not sure if it works 100% in my testing. - Some of the tuning in the firmware seems to ensure much better performance when in a RAID0 setup than using the two devices seperately. I have not tested booting from the SSD, because all of this was developed and tested remotely from the actual hardware. Signed-off-by: Robin H.

The recent data from Ingo[1] shows that this is one of several instances that has a significant impact on compile times, and it should be targeted for factoring out (as done here). Note that several commonly used header files in include/* directly include <linux/module.h> themselves (some 34 of them!) The most commonly used ones of these will have to be made independent of module.h before the full benefit of this change can be realized. We also transition THIS_MODULE from module.h to export.h, since there are lots of files with subsystem structs that in turn will have a struct module *owner and only be doing: .owner = THIS_MODULE; and absolutely nothing else modular. So, we also want to have the THIS_MODULE definition present in the lightweight header.

We can clean this up by removing the structure from the i_complted_io_list, and use this as the locking mechanism to prevent ext4_flush_completed_IO() racing against ext4_end_io_work(), instead of clearing the EXT4_IO_END_UNWRITTEN in io->flag. In addition, if the ext4_convert_unwritten_extents() returns an error, we no longer keep the end_io structure on the linked list. This doesn't help, because it tends to lock up the file system and wedges the system. That's one way to call attention to the problem, but it doesn't help the overall robustness of the system.

In late 2010 we were seeing that various +different targets were rolling their own data strutures, for example: + +- Mikulas Patocka's multisnap implementation +- Heinz Mauelshagen's thin provisioning target +- Another btree-based caching target posted to dm-devel +- Another multi-snapshot target based on a design of Daniel Phillips + +Maintaining these data structures takes a lot of work, so if possible +we'd like to reduce the number. + +The persistent-data library is an attempt to provide a re-usable +framework for people who want to store metadata in device-mapper +targets. It's currently used by the thin-provisioning target and an +upcoming hierarchical storage target. + +Overview +======== + +The main documentation is in the header files which can all be found +under drivers/md/persistent-data. + +The block manager +----------------- + +dm-block-manager.[hc] + +This provides access to the data on disk in fixed sized-blocks. There +is a read/write locking interface to prevent concurrent accesses, and +keep data that is being used in the cache. + +Clients of persistent-data are unlikely to use this directly. + +The transaction manager +----------------------- + +dm-transaction-manager.[hc] + +This restricts access to blocks and enforces copy-on-write semantics. +The only way you can get hold of a writable block through the +transaction manager is by shadowing an existing block (ie. doing +copy-on-write) or allocating a fresh one. Shadowing is elided within +the same transaction so performance is reasonable. The commit method +ensures that all data is flushed before it writes the superblock. +On power failure your metadata will be as it was when last committed. + +The Space Maps +-------------- + +dm-space-map.h +dm-space-map-metadata.[hc] +dm-space-map-disk.[hc] + +On-disk data structures that keep track of reference counts of blocks. +Also acts as the allocator of new blocks. Currently two +implementations: a simpler one for managing blocks on a different +device (eg. thinly-provisioned data blocks); and one for managing +the metadata space. The latter is complicated by the need to store +its own data within the space it's managing. + +The data structures +------------------- + +dm-btree.[hc] +dm-btree-remove.c +dm-btree-spine.c +dm-btree-internal.h + +Currently there is only one data structure, a hierarchical btree. +There are plans to add more. For example, something with an +array-like interface would see a lot of use. + +The btree is 'hierarchical' in that you can define it to be composed +of nested btrees, and take multiple keys. For example, the +thin-provisioning target uses a btree with two levels of nesting. +The first maps a device id to a mapping tree, and that in turn maps a +virtual block to a physical block. + +Values stored in the btrees can have arbitrary size. Keys are always +64bits, although nesting allows you to use multiple keys. diff --git a/drivers/md/persistent-data/Kconfig b/drivers/md/persistent-data/Kconfig new file mode 100644 index 0000000000000..ceb359050a599 --- /dev/null +++ b/drivers/md/persistent-data/Kconfig @@ -0,0 +1,8 @@ +config DM_PERSISTENT_DATA + tristate + depends on BLK_DEV_DM && EXPERIMENTAL + select LIBCRC32C + select DM_BUFIO + ---help--- + Library providing immutable on-disk data structure support for + device-mapper targets such as the thin provisioning target. diff --git a/drivers/md/persistent-data/Makefile b/drivers/md/persistent-data/Makefile new file mode 100644 index 0000000000000..cfa95f6622300 --- /dev/null +++ b/drivers/md/persistent-data/Makefile @@ -0,0 +1,11 @@ +obj-$(CONFIG_DM_PERSISTENT_DATA) += dm-persistent-data.o +dm-persistent-data-objs := \ + dm-block-manager.o \ + dm-space-map-checker.o \ + dm-space-map-common.o \ + dm-space-map-disk.o \ + dm-space-map-metadata.o \ + dm-transaction-manager.o \ + dm-btree.o \ + dm-btree-remove.o \ + dm-btree-spine.o diff --git a/drivers/md/persistent-data/dm-block-manager.c b/drivers/md/persistent-data/dm-block-manager.c new file mode 100644 index 0000000000000..0317ecdc6e539 --- /dev/null +++ b/drivers/md/persistent-data/dm-block-manager.c @@ -0,0 +1,620 @@ +/* + * Copyright (C) 2011 Red Hat, Inc. + * + * This file is released under the GPL. + */ +#include "dm-block-manager.h" +#include "dm-persistent-data-internal.h" +#include "../dm-bufio.h" + +#include <linux/crc32c.h> +#include <linux/module.h> +#include <linux/slab.h> +#include <linux/rwsem.h> +#include <linux/device-mapper.h> +#include <linux/stacktrace.h> + +#define DM_MSG_PREFIX "block manager" + +/*----------------------------------------------------------------*/ + +/* + * This is a read/write semaphore with a couple of differences. + * + * i) There is a restriction on the number of concurrent read locks that + * may be held at once.

The 'thin' target is used to create instances of the virtual devices that are hosted in the 'thin-pool' target. The thin-pool target provides data sharing among devices. This sharing is made possible using the persistent-data library in the previous patch. The main highlight of this implementation, compared to the previous implementation of snapshots, is that it allows many virtual devices to be stored on the same data volume, simplifying administration and allowing sharing of data between volumes (thus reducing disk usage). Another big feature is support for arbitrary depth of recursive snapshots (snapshots of snapshots of snapshots ...). The previous implementation of snapshots did this by chaining together lookup tables, and so performance was O(depth). This new implementation uses a single data structure so we don't get this degradation with depth.

This simplifies administration and +allows the sharing of data between volumes, thus reducing disk usage. + +Another significant feature is support for an arbitrary depth of +recursive snapshots (snapshots of snapshots of snapshots ...). The +previous implementation of snapshots did this by chaining together +lookup tables, and so performance was O(depth). This new +implementation uses a single data structure to avoid this degradation +with depth. Fragmentation may still be an issue, however, in some +scenarios. + +Metadata is stored on a separate device from data, giving the +administrator some freedom, for example to: + +- Improve metadata resilience by storing metadata on a mirrored volume + but data on a non-mirrored one. + +- Improve performance by storing the metadata on SSD. + +Status +====== + +These targets are very much still in the EXPERIMENTAL state. Please +do not yet rely on them in production. But do experiment and offer us +feedback. Different use cases will have different performance +characteristics, for example due to fragmentation of the data volume. + +If you find this software is not performing as expected please mail +dm-devel@redhat.com with details and we'll try our best to improve +things for you. + +Userspace tools for checking and repairing the metadata are under +development. + +Cookbook +======== + +This section describes some quick recipes for using thin provisioning. +They use the dmsetup program to control the device-mapper driver +directly. End users will be advised to use a higher-level volume +manager such as LVM2 once support has been added. + +Pool device +----------- + +The pool device ties together the metadata volume and the data volume. +It maps I/O linearly to the data volume and updates the metadata via +two mechanisms: + +- Function calls from the thin targets + +- Device-mapper 'messages' from userspace which control the creation of new + virtual devices amongst other things. + +Setting up a fresh pool device +------------------------------ + +Setting up a pool device requires a valid metadata device, and a +data device. If you do not have an existing metadata device you can +make one by zeroing the first 4k to indicate empty metadata. + + dd if=/dev/zero of=$metadata_dev bs=4096 count=1 + +The amount of metadata you need will vary according to how many blocks +are shared between thin devices (i.e. through snapshots). If you have +less sharing than average you'll need a larger-than-average metadata device. + +As a guide, we suggest you calculate the number of bytes to use in the +metadata device as 48 * $data_dev_size / $data_block_size but round it up +to 2MB if the answer is smaller. The largest size supported is 16GB. + +If you're creating large numbers of snapshots which are recording large +amounts of change, you may need find you need to increase this. + +Reloading a pool table +---------------------- + +You may reload a pool's table, indeed this is how the pool is resized +if it runs out of space. (N.B. While specifying a different metadata +device when reloading is not forbidden at the moment, things will go +wrong if it does not route I/O to exactly the same on-disk location as +previously.) + +Using an existing pool device +----------------------------- + + dmsetup create pool \ + --table "0 20971520 thin-pool $metadata_dev $data_dev \ + $data_block_size $low_water_mark" + +$data_block_size gives the smallest unit of disk space that can be +allocated at a time expressed in units of 512-byte sectors. People +primarily interested in thin provisioning may want to use a value such +as 1024 (512KB). People doing lots of snapshotting may want a smaller value +such as 128 (64KB). If you are not zeroing newly-allocated data, +a larger $data_block_size in the region of 256000 (128MB) is suggested. +$data_block_size must be the same for the lifetime of the +metadata device. + +$low_water_mark is expressed in blocks of size $data_block_size. If +free space on the data device drops below this level then a dm event +will be triggered which a userspace daemon should catch allowing it to +extend the pool device. Only one such event will be sent. +Resuming a device with a new table itself triggers an event so the +userspace daemon can use this to detect a situation where a new table +already exceeds the threshold. + +Thin provisioning +----------------- + +i) Creating a new thinly-provisioned volume. + + To create a new thinly- provisioned volume you must send a message to an + active pool device, /dev/mapper/pool in this example. + + dmsetup message /dev/mapper/pool 0 "create_thin 0" + + Here '0' is an identifier for the volume, a 24-bit number.

When you take an internal snapshot you clone the root node + * of the origin btree. After this there is no concept of an origin or a + * snapshot. They are just two device trees that happen to point to the + * same data blocks. + * + * When we get a write in we decide if it's to a shared data block using + * some timestamp magic. If it is, we have to break sharing. + * + * Let's say we write to a shared block in what was the origin. The + * steps are: + * + * i) plug io further to this physical block. (see bio_prison code). + * + * ii) quiesce any read io to that shared data block. Obviously + * including all devices that share this block. (see deferred_set code) + * + * iii) copy the data block to a newly allocate block. This step can be + * missed out if the io covers the block. (schedule_copy). + * + * iv) insert the new mapping into the origin's btree + * (process_prepared_mappings). This act of inserting breaks some + * sharing of btree nodes between the two devices. Breaking sharing only + * effects the btree of that specific device. Btrees for the other + * devices that share the block never change. The btree for the origin + * device as it was after the last commit is untouched, ie. we're using + * persistent data structures in the functional programming sense. + * + * v) unplug io to this physical block, including the io that triggered + * the breaking of sharing. + * + * Steps (ii) and (iii) occur in parallel. + * + * The metadata _doesn't_ need to be committed before the io continues. We + * get away with this because the io is always written to a _new_ block. + * If there's a crash, then: + * + * - The origin mapping will point to the old origin block (the shared + * one). This will contain the data as it was before the io that triggered + * the breaking of sharing came in. + * + * - The snap mapping still points to the old block. As it would after + * the commit. + * + * The downside of this scheme is the timestamp magic isn't perfect, and + * will continue to think that data block in the snapshot device is shared + * even after the write to the origin has broken sharing. I suspect data + * blocks will typically be shared by many different devices, so we're + * breaking sharing n + 1 times, rather than n, where n is the number of + * devices that reference this data block.

When device mapper targets use a device they normally call dm_get_device which includes it in the device list returned to userspace applications such as LVM through the DM_TABLE_DEPS ioctl. Userspace log devices don't use dm_get_device as userspace opens them so they are missing from the list of dependencies. This patch extends the DM_ULOG_CTR operation to allow userspace to respond with the name of the log device (if appropriate) to be registered via 'dm_get_device'. DM_ULOG_REQUEST_VERSION is incremented. This is backwards compatible. If the kernel and userspace log server have both been updated, the new information will be passed down to the kernel and the device will be registered. If the kernel is new, but the log server is old, the log server will not pass down any device information and the kernel will simply bypass the device registration as before. If the kernel is old but the log server is new, the log server will see the old version number and not pass the device info.

We have found some bugs that the flag is set while leaving i_aiodio_unwritten unchanged(commit 32c80b32c053d).

ead53f22dc646d91a1b6201b9f44dd47d7d88c34 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker <paul.gortmaker@windriver.com> Date: Fri, 22 Jul 2011 14:24:04 -0400 Subject: [PATCH 0807/1531] powerpc: remove non-required uses of include <linux/module.h> None of the files touched here are modules, and they are not exporting any symbols either -- so there is no need to be including the module.h. Builds of all the files remains successful. Even kernel/module.c does not need to include it, since it includes linux/moduleloader.h instead.

symbol exporters to use export.h not module.h Many of the core sparc kernel files are not modules, but just including module.h for exporting symbols. Now these files can use the lighter footprint export.h for this role.

<paul.gortmaker@windriver.com> Date: Fri, 27 May 2011 16:14:23 -0400 Subject: [PATCH 0846/1531] drivers/net: Add export.h to files using EXPORT_SYMBOL/THIS_MODULE These were getting the macros from an implicit module.h include via device.h, but we are planning to clean that up. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> drivers/net: Add export.h to wireless/brcm80211/brcmfmac/bcmsdh.c This relatively recently added file uses EXPORT_SYMBOL and hence needs export.h included so that it is compatible with the module.h split up work.

Date: Thu, 22 Sep 2011 09:34:58 -0400 Subject: [PATCH 0869/1531] sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where needed These aren't modules, but they do make use of these macros, so they will need export.h to get that definition. Previously, they got it via the implicit module.h inclusion.

2011 16:09:31 -0400 Subject: [PATCH 0874/1531] usb: Add module.h to drivers/usb consumers who really use it. The situation up to this point meant that module.h was pretty much everywhere, regardless of whether you asked for it or not. We are fixing that, so give the USB folks who want it an actual include of it.

Use the lightweight version of the header that has just THIS_MODULE and EXPORT_SYMBOL variants.

But having all of <linux/module.h> along for the ride is overkill and slows down compiles by a measureable amount, since it in turn includes lots of headers. Since the inline is never used anywhere in the kernel[1], we can just remove it, and then also remove the module.h include as well. In all the many crypto modules, there were some relying on crypto.h including module.h -- for them we now explicitly call out module.h for inclusion.

The worst culprit was probably device.h since it is used everywhere. This file also had an implicit dependency/usage of mutex.h which was masked by module.h, and is also fixed here at the same time. There are over a dozen other headers that simply declare the struct instead of pulling in the whole file, so follow their lead and simply make it a few more. Most of the implicit dependencies on module.h being present by these headers pulling it in have been now weeded out, so we can finally make this change with hopefully minimal breakage.

Recent commit "irq: Track the owner of irq descriptor" in commit ID b6873807a7143b7 placed module.h into linux/irq.h but we are trying to limit module.h inclusion to just C files that really need it, due to its size and number of children includes. This targets just reversing that include. Add in the basic "struct module" since that is all we really need to ensure things compile. In theory, b687380 should have added the module.h include to the irqdesc.h header as well, but the implicit module.h everywhere presence masked this from showing up. So give it the "struct module" as well. As for the C files, irqdesc.c is only using THIS_MODULE, so it does not need module.h - give it export.h instead. The C file irq/manage.c is now (as of b687380) using try_module_get and module_put and so it needs module.h (which it already has). Also convert the irq_alloc_descs variants to macros, since all they really do is is call the __irq_alloc_descs primitive. This avoids including export.h and no debug info is lost.

These definitions, although not exported, have been used by iptables and other userspace applications like miniupnpd since long time. Basically, these userspace tools included some internal definition of the required structures and they assume no changes in the binary representation (which is OK indeed). To resolve this situation, this patch makes public the required structure and install them in INSTALL_HDR_PATH. See: https://bugs.gentoo.org/376873, for more information. This patch is heavily based on the initial patch sent by: Anthony G.

There's no broader range test yet to double check if the error decoding logic will actually point to the right DIMM, so use it with care. More tests are required to be sure that the driver will work on all different types of memory configurations. If you're willing to risk using it, I suggest you to enable EDAC debugs for your test machines, as the debug logs helps to track what's going inside the driver. Please feed me with bug reports, if you notice that the driver is miss-behaving.

The generic detection of hid-mt devices has two major flaws, and was merged prematurely. Firstly, the hid-multitouch gets loaded even when the device is handled by a special device. Secondly, the patch only partially duplicates the device whitelist already present in hid-core, effectively rendering a number of devices non-functional.

But there is no such problem when uses miimon. (Take igb for example) I find that the reason is that after dev_open() in bond_enslave(), bond_update_speed_duplex() will call igb_get_settings() , but in that function, it runs ethtool_cmd_speed_set(ecmd, -1); ecmd->duplex = -1; because igb get an error value of status. So even dev_open() is called, but the device is not really ready to get its settings. Maybe it is safe for us to call igb_get_settings() only after this message shows up, that is "igb: p4p1 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX". So I prefer to update the speed and duplex for a slave when reseices NETDEV_CHANGE/NETDEV_UP event. Changelog V2: 1 remove the "fake 100/Full" logic in bond_update_speed_duplex(), set speed and duplex to -1 when it gets error value of speed and duplex. 2 delete the warning in bond_enslave() if bond_update_speed_duplex() returns error. 3 make bond_info_show_slave() handle bad values of speed and duplex.

Turns out that tty_open fails, because the hvc_alloc was not yet done. In former times this could not happen, since the probe function automatically called hvc_alloc. With newer versions (multiport) some host<->guest interaction is required before hvc_alloc is called. This might be too late, especially if an initramfs is involved. Lets use a completion if we have multiport and an early console.

This should allow environments like qemu to use virtio-based block & network devices even on platforms without PCI support. One can define and register a platform device which resources will describe memory mapped control registers and "mailbox" interrupt. Such device can be also instantiated using the Device Tree node with compatible property equal "virtio,mmio".

This means we'll run out of numbers after a while. It also could cause confusion about the disk name in the case of hot-plugging disks. Change virtio-blk to use ida to allocate index, instead.

Wrap dentry_lru_del() and use the new _prune() helper in the cases where we are about to unhash and kill the dentry. This will be used by Ceph to maintain a flag indicating whether the complete contents of a directory are contained in the dcache, allowing it to satisfy lookups and readdir without addition server communication. Renumber a few DCACHE_* #defines to group DCACHE_OP_PRUNE with the other DCACHE_OP_ bits.

By default Squashfs sets the device block size (sb_min_blocksize) to 1K or the smallest block size supported by the block device (if larger). This, because blocks are packed together and unaligned in Squashfs, should reduce latency. This, however, gives poor performance on MTD NAND devices where the optimal I/O size is 4K (even though the devices can support smaller block sizes). Using a 4K device block size may also improve overall I/O performance for some file access patterns (e.g. sequential accesses of files in filesystem order) on all media.

Also, when only a single capture source is available, the multi-streams don't make sense, too. With this patch, the driver checks such condition and skips the alt stream appropriately.

He then found the problem could also theoretically materialize with page_cache_get_speculative() during the speculative radix tree lookups that uses get_page_unless_zero() in SMP if the radix tree page is freed and reallocated and get_user_pages is called on it before page_cache_get_speculative has a chance to call get_page_unless_zero(). So the best way to fix the problem is to keep page_tail->_count zero at all times. This will guarantee that get_page_unless_zero() can never succeed on any tail page. page_tail->_mapcount is guaranteed zero and is unused for all tail pages of a compound page, so we can simply account the tail page references there and transfer them to tail_page->_count in __split_huge_page_refcount() (in addition to the head_page->_mapcount). While debugging this s/_count/_mapcount/ change I also noticed get_page is called by direct-io.c on pages returned by get_user_pages. That wasn't entirely safe because the two atomic_inc in get_page weren't atomic. As opposed to other get_user_page users like secondary-MMU page fault to establish the shadow pagetables would never call any superflous get_page after get_user_page returns. It's safer to make get_page universally safe for tail pages and to use get_page_foll() within follow_page (inside get_user_pages()). get_page_foll() is safe to do the refcounting for tail pages without taking any locks because it is run within PT lock protected critical sections (PT lock for pte and page_table_lock for pmd_trans_huge). The standard get_page() as invoked by direct-io instead will now take the compound_lock but still only for tail pages. The direct-io paths are usually I/O bound and the compound_lock is per THP so very finegrined, so there's no risk of scalability issues with it. A simple direct-io benchmarks with all lockdep prove locking and spinlock debugging infrastructure enabled shows identical performance and no overhead. So it's worth it. Ideally direct-io should stop calling get_page() on pages returned by get_user_pages(). The spinlock in get_page() is already optimized away for no-THP builds but doing get_page() on tail pages returned by GUP is generally a rare operation and usually only run in I/O paths. This new refcounting on page_tail->_mapcount in addition to avoiding new RCU critical sections will also allow the working set estimation code to work without any further complexity associated to the tail page refcounting with THP.

This is a longstanding issue pre-thp inclusion. It's totally unclear how these page_cache_add_speculative and pte_val(pte) != pte_val(*ptep) checks are necessary across all the powerpc gup_fast code, when x86 doesn't need any of that: there's no way the page can be freed with irq disabled so we're guaranteed the atomic_inc will happen on a page with page_count > 0 (so not needing the speculative check). The pte check is also meaningless on x86: no need to rollback on x86 if the pte changed, because the pte can still change a CPU tick after the check succeeded and it won't be rolled back in that case. The important thing is we got a reference on a valid page that was mapped there a CPU tick ago. So not knowing the soft tlb refill code of ppc64 in great detail I'm not removing the "speculative" page_count increase and the pte checks across all the code, but unless there's a strong reason for it they should be later cleaned up too. If a pte can change from huge to non-huge (like it could happen with THP) passing a pte_t *ptep to gup_hugepte() would also require to repeat the is_hugepd in gup_hugepte(), but that shouldn't happen with hugetlbfs only so I'm not altering that.

This proves to be because the filesystem has a corrupted MDB extent record, where the extents file does not fit into the first three extents in the file record (the first blocks). In hfs_get_block() when looking up the blocks for the extent file (HFS_EXT_CNID), it fails the first blocks special case, and falls through to the extent code (which ultimately calls hfs_find_init()) which is in the process of being initialised. Hfs avoids this scenario by always having the extents b-tree fitting into the first blocks (the extents B-tree can't have overflow extents). The fix is to check at mount time that the B-tree fits into first blocks, i.e. fail if HFS_I(inode)->alloc_blocks >= HFS_I(inode)->first_blocks Note, the existing commit 47f365eb57573 ("hfs: fix oops on mount with corrupted btree extent records") becomes subsumed into this as a special case, but only for the extents B-tree (HFS_EXT_CNID), it is perfectly acceptable for the catalog B-Tree file to grow beyond three extents, with the remaining extent descriptors in the extents overfow.

The change from allocating base with kmalloc to alloc_page() has the base not calling kmemleak_alloc() which adds the pointer to the object_tree_root, but kmemleak_not_leak() adds it to the crt_early_log[] table. On kmemleak_init(), the entry is found in the early_log[] but not the object_tree_root, and this error message is displayed. If alloc_page() fails then it defaults back to vmalloc() which still uses the kmemleak_alloc() which makes us still need the kmemleak_not_leak() call. The solution is to call the kmemleak_alloc() directly if the alloc_page() succeeds.

The memcg implementation of comparing those lists instead reports whether the whole memcg is low on the requested type of inactive pages, considering all nodes and zones. This can lead to an oversized active list not being scanned because of the state of the other lists in the memcg, as well as an active list being scanned while its corresponding inactive list has enough pages. Not only is this wrong, it's also a scalability hazard, because the global memory state over all nodes and zones has to be gathered for each memcg and zone scanned. Make these calculations purely based on the size of the two LRU lists that are actually affected by the outcome of the decision.

This could incur a significant delay, however, especially in low memory conditions because the page allocator is blocking and reclaim requires get_mems_allowed() itself. It is not atypical to see writes to cpuset.mems take over 2 seconds to complete, for example. In low memory conditions, this is problematic because it's one of the most imporant times to change cpuset.mems in the first place! The only way a task's set of allowable nodes may change is through cpusets by writing to cpuset.mems and when attaching a task to a generic code is not reading the nodemask with get_mems_allowed() at the same time, and then clearing all the old nodes. This prevents the possibility that a reader will see an empty nodemask at the same time the writer is storing a new nodemask. If at least one node remains unchanged, though, it's possible to simply set all new nodes and then clear all the old nodes. Changing a task's nodemask is protected by cgroup_mutex so it's guaranteed that two threads are not changing the same task's nodemask at the same time, so the nodemask is guaranteed to be stored before another thread changes it and determines whether a node remains set or not.

But one may open any of these files and run any setuid program, keeping opened file descriptors. As there are permission checks on open(), but not on readdir() and read(), operations on the kept file descriptors will not be checked. It makes it possible to violate procfs permission model. Reading fdinfo/* may disclosure current fds' position and flags, reading directory contents of fdinfo/ and fd/ may disclosure the number of opened files by the target task. This information is not sensible per se, but it can reveal some private information (like length of a password stored in a file) under certain conditions. Used existing (un)lock_trace functions to check for ptrace_may_access(), but instead of using EPERM return code from it use EACCES to be consistent with existing proc_pid_follow_link()/proc_pid_readlink() return code. If they differ, attacker can guess what fds exist by analyzing stat() return code. Patched handlers: stat() for fd/*, stat() and read() for fdindo/*, readdir() and lookup() for fd/ and fdinfo/.

This approach provides similar properties to specifying a device and partition number, but using the UUID as the unique path prior to evaluating the offset. For example, root=PARTUUID=99DE9194-FC15-4223-9192-FC243948F88B/PARTNROFF=1 selects the partition with UUID 99DE.. then select the next partition. This change is motivated by a particular usecase in Chromium OS where the bootloader can easily determine what partition it is on (by UUID) but doesn't perform general partition table walking. That said, support for this model provides a direct mechanism for the user to modify the root partition to boot without specifically needing to extract each UUID or update the bootloader explicitly when the root partition UUID is changed (if it is recreated to be larger, for instance). Pinning to a /boot-style partition UUID allows the arbitrary root partition reconfiguration/modifications with slightly less ambiguity than just [dev][partition] and less stringency than the specific root partition UUID.

Platform data [1] are used to specify the GPIO pin number, label, assert event edge type, and whether clear events are captured. This driver is based on the work by Ricardo Martins who submitted an initial implementation [2] of a PPS IRQ client driver to the linuxpps mailing-list on Dec 3 2010.

The reason is that we take it for every I/O submitted (see __aio_get_req). Since we know how many I/Os are passed to io_submit, we can preallocate the kiocbs in batches, reducing the number of times we take and release the lock. In my testing, I was able to reduce the amount of time spent in _raw_spin_lock_irq by .56% (average of 3 runs). The command I used to test this was: aio-stress -O -o 2 -o 3 -r 8 -d 128 -b 32 -i 32 -s 16384 <dev> I also tested the patch with various numbers of events passed to io_submit, and I ran the xfstests aio group of tests to ensure I didn't break anything.

This lock protects idr map, and serializes calls to idr_get_next() in css_get_next() (which is used during the memcg hierarchy walk). Since idr_get_next() is just doing a look up, we need only serialize it with respect to idr_remove()/idr_get_new(). By making the ss->id_lock a rwlock, contention is greatly reduced and performance improves. Tested: cat a 256m file from a ramdisk in a 128m container 50 times on each core (one file + container per core) in parallel on a NUMA machine. Result is the time for the test to complete in 1 of the containers. Both kernels included Johannes' memcg-aware global reclaim patches.

It was used in the error reporting mechanism at layout_return. This function is kept intact. (Later patch will rename objlayout_io_state => objlayout_io_res) 2. Carrier of rw io members into the objio_read/write_paglist API. This is removed in this patch. The {r,w}data received from NFS are passed directly to the objio_{read,write}_paglist API. The io_engine is now allocating it's own IO state as part of the read/write. The minimal functionality that was part of the generic allocation is passed to the io_engine. So part of this patch is rename of: ios->ol_state.foo => ios->foo At objlayout_{read,write}_done an objlayout_io_state is passed that denotes the result of the IO. (Hence the later name change). If the IO is successful objlayout calls an objio_free_result() API immediately (Which for objio_osd causes the release of the io_state). If the IO ended in an error it is hanged onto until reported in layout_return and is released later through the objio_free_result() API. (All this is not new just renamed and cleaned) Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> --- fs/nfs/objlayout/objio_osd.c | 94 +++++++++++++++++--------- fs/nfs/objlayout/objlayout.c | 124 +++++++++-------------------------- fs/nfs/objlayout/objlayout.h | 36 +++++----- 3 files changed, 112 insertions(+), 142 deletions(-) diff --git a/fs/nfs/objlayout/objio_osd.c b/fs/nfs/objlayout/objio_osd.c index 0c7c9ec24e672..48eb91aad5540 100644 --- a/fs/nfs/objlayout/objio_osd.c +++ b/fs/nfs/objlayout/objio_osd.c @@ -148,6 +148,13 @@ struct objio_state { /* Generic layer */ struct objlayout_io_state ol_state;

Though it will be removed soon, also the raid engine is modified to actually compile, possibly run, with the new types. So it is the same old raid engine but with some new ORE types. For Ease of reviewing, some of the old code is "#if 0" but is not removed so the diff command works better. The old code will be removed in the 3rd patch.

(Object Raid Engine). objio_state holds a pointer to an ore_io_state. Once we have an ore_io_state at hand we can call the ore for reading/writing. We register on the done path to kick off the nfs io_done mechanism. Again for Ease of reviewing the old code is "#if 0" but is not removed so the diff command works better. The old code will be removed in the next patch. fs/exofs/Kconfig::ORE is modified to also be auto-included if PNFS_OBJLAYOUT is set. Since we now depend on ORE.

The source is unmodified, with the only changes I've made so far were that I created a Kconfig and Makefile so that the code builds in a standard v4l-dvb tree. This driver requires firmware (which Abilis has provided with redistribution terms which will allow it to be bundled in the Linux distributions). The firmware can be downloaded from here: Thanks to Rainer Miethling from PCTV Systems for working to get the driver released (for use with the PCTV 74e) and Pierrick Hascoet from Abilis for authoring the driver.

Note that the product name field has not yet been abstracted out, so it will still identify itself as a PCTV 74e. The driver was originally built by the chipset manufacturer so that the product vendor can specify the device name via a #define, but wasn't setup to support multiple products from the same build of the driver. Thanks to Joerg Unglaub for suggesting this change.

4860c73804c6e7ef8e69f98958489bb2bea6f6d2 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab <mchehab@redhat.com> Date: Tue, 1 Nov 2011 22:23:55 -0200 Subject: [PATCH 1291/1531] staging: Move media drivers to staging/media In practice, it is being hard to distinguish when a patch should go to staging tree or to the media tree. Better to distinguish it, by putting the media drivers at a separate staging directory. Newer staging drivers that include anything with "dvb*.h", "v4l2*.h" or "videodev2.h" should go to the drivers/staging/media tree.

144060fee07e9c22e179d00819c83c86fbcbf82c. It causes a resume regression for Andi on his Acer Aspire 1830T post 3.1. The screen just stays black after wakeup. Also, it really looks like the wrong way to suspend and resume perf events: I think they should be done as part of the CPU suspend and resume, rather than as a notifier that does smp_call_function().

This patch allows consistent cropping for rectangles also larger than VGA and cleans up multiple other issues in this area. It still doesn't add support for proper scaling, using the sensor own scaler, so input window is still always equal to the output frame.

This patch adds support for buffers of different sizes on the same buffer-queue to vb2.

This makes most of the soc-camera client drivers also usable outside of the soc-camera framework. After this change all what is needed for these drivers to function are inclusions of soc-camera headers for some convenience macros, suitably configured platform data, which is anyway always required, and loaded soc-camera core module for library functions. If desired, these library functions can be made generic in the future and moved to a more neutral location. The only two client drivers, that still depend on soc-camera are: mt9t031: it uses struct video_device for its PM. Since no hardware is available, alternative methods cannot be tested. ov6650: it uses struct soc_camera_device to pass its sense data back to the bridge driver. A generic v4l2-subdevice approach should be developed to perform this.

This change refactors that code so that a hardware-specific, but OS- and application-agnostic header, is created: <arch/opcode.h>. This header is then exported to userspace along with the other <arch> headers and can be used to build userspace code; in particular, it is used by glibc as part of implementing the backtrace() function. The new header, together with a header that specifically describes the disassembly code (<asm/tile-desc.h> with _32 and _64 variants), replaces the old <asm/opcode-tile*.h> and <asm/opcode_constants*.h> headers. As part of this change, we are also renaming the 32-bit constants from TILE_xxx to TILEPRO_xxx to better reflect the fact that they are specific to the TILEPro architecture, and not to TILE-Gx and any successor "tile" architecture chips.

This is intended to be a 'opt-in' feature for fabric modules that includes the following functions to provide a mechinism for fabric modules to track se_cmd via se_session->sess_cmd_list: *) target_get_sess_cmd() - Add se_cmd to sess->sess_cmd_list, called from fabric module incoming I/O path. *) target_put_sess_cmd() - Check for completion or drop se_cmd from ->sess_cmd_list *) target_splice_sess_cmd_list() - Splice active I/O list from ->sess_cmd_list to ->sess_wait_list, can called with HW fabric lock held. *) target_wait_for_sess_cmds() - Walk ->sess_wait_list waiting on individual ->cmd_wait_comp. Optional transport_wait_for_tasks() call. target_splice_sess_cmd_list() is allowed to be called under HW fabric lock, and performs the splice into se_sess->sess_wait_list and set se_cmd->cmd_wait_set. Then target_wait_for_sess_cmds() walks the list waiting for individual target_put_sess_cmd() fabric callbacks to complete. It also adds TFO->check_release_cmd() to split the completion and memory release calls, where a fabric module uses target_put_sess_cmd() to check for I/O completion during session shutdown. This is currently pushed out into fabric modules as current fabric code may sleep here waiting for TFO->check_stop_free() to complete in main response path, and because target_wait_for_sess_cmds() calling TFO->release_cmd() to free fabric descriptor memory directly.

It would then unconditionally try return a flush completion via qib_send_complete() for an invalid wqe, or worse a valid one that is not queued. The panic results when the completion code tries to maintain an MR reference count for a NULL MR. This fix modifies logic to only send one completion per qib_make_rc_req() call and changing the completion status from IB_WC_SUCCESS to IB_WC_WR_FLUSH_ERR as the completions progress. The outer loop will call as many times as necessary to flush the queue.

Bhat" <srivatsa.bhat@linux.vnet.ibm.com> Date: Thu, 3 Nov 2011 00:59:25 +0100 Subject: [PATCH 1486/1531] PM / Sleep: Fix race between CPU hotplug and freezer The CPU hotplug notifications sent out by the _cpu_up() and _cpu_down() functions depend on the value of the 'tasks_frozen' argument passed to them (which indicates whether tasks have been frozen or not). (Examples for such CPU hotplug notifications: CPU_ONLINE, CPU_ONLINE_FROZEN, CPU_DEAD, CPU_DEAD_FROZEN). Thus, it is essential that while the callbacks for those notifications are running, the state of the system with respect to the tasks being frozen or not remains unchanged, *throughout that duration*. Hence there is a need for synchronizing the CPU hotplug code with the freezer subsystem. Since the freezer is involved only in the Suspend/Hibernate call paths, this patch hooks the CPU hotplug code to the suspend/hibernate notifiers PM_[SUSPEND|HIBERNATE]_PREPARE and PM_POST_[SUSPEND|HIBERNATE] to prevent the race between CPU hotplug and freezer, thus ensuring that CPU hotplug notifications will always be run with the state of the system really being what the notifications indicate, _throughout_ their execution time.

This breaks good working of newer hardware. The disabling of the SMI by the TCO logic dates back from the i810-tco driver from Nils Faerber (around 28 July 2000). The reason for this was that some BIOSes install handlers reset or disable the watchdog timer instead of resetting the system. The trick to fix this was to disable the SMI (by clearing the SMI_TCO_EN bit of the SMI_EN register) to prevent this from happening. This however has strange effects on newer hardware. So we are in a situation that a fix for broken old hardware affects newer hardware. The correct solution is to make this fix an option (with the new module parameter: turn_SMI_watchdog_clear_off) so that the default behaviour is the unfixed version. the next patch will be to move this in the start and stop functions of the driver and to add a new module parameter for the global_smi_en bit and to get rid of the vendor_support code. This fix can have an effect on old (typical ICH & ICH2 chipsets) motherboards that have a broken BIOS implementation concerning TCO logic. In these case the module parameter turn_SMI_watchdog_clear_off=1 will need to be added.

Make sure it is 0 if you + don't have further support! + + WDIOC_SETOPTIONS: + No preparations needed + + WDIOC_KEEPALIVE: + If wanted, options in watchdog_info need to have WDIOF_KEEPALIVEPING + set + + WDIOC_SETTIMEOUT: + Options in watchdog_info need to have WDIOF_SETTIMEOUT set + and a set_timeout-callback has to be defined. The core will also + do limit-checking, if min_timeout and max_timeout in the watchdog + device are set. All is optional. + + WDIOC_GETTIMEOUT: + No preparations needed + + Other IOCTLs can be served using the ioctl-callback. Note that this is mainly + intended for porting old drivers; new drivers should not invent private IOCTLs. + Private IOCTLs are processed first. When the callback returns with + -ENOIOCTLCMD, the IOCTLs of the framework will be tried, too. Any other error + is directly given to the user. + +Example conversion: + +-static const struct file_operations s3c2410wdt_fops = { +- .owner = THIS_MODULE, +- .llseek = no_llseek, +- .write = s3c2410wdt_write, +- .unlocked_ioctl = s3c2410wdt_ioctl, +- .open = s3c2410wdt_open, +- .release = s3c2410wdt_release, +-}; + +Check the functions for device-specific stuff and keep it for later +refactoring. The rest can go. + + +Remove the miscdevice +--------------------- + +Since the file_operations are gone now, you can also remove the 'struct +miscdevice'. The framework will create it on watchdog_dev_register() called by +watchdog_register_device(). + +-static struct miscdevice s3c2410wdt_miscdev = { +- .minor = WATCHDOG_MINOR, +- .name = "watchdog", +- .fops = &s3c2410wdt_fops, +-}; + + +Remove obsolete includes and defines +------------------------------------ + +Because of the simplifications, a few defines are probably unused now. Remove +them. Includes can be removed, too. For example: + +- #include <linux/fs.h> +- #include <linux/miscdevice.h> (if MODULE_ALIAS_MISCDEV is not used) +- #include <linux/uaccess.h> (if no custom IOCTLs are used) + + +Add the watchdog operations +--------------------------- + +All possible callbacks are defined in 'struct watchdog_ops'. You can find it +explained in 'watchdog-kernel-api.txt' in this directory. start(), stop() and +owner must be set, the rest are optional. You will easily find corresponding +functions in the old driver. Note that you will now get a pointer to the +watchdog_device as a parameter to these functions, so you probably have to +change the function header. Other changes are most likely not needed, because +here simply happens the direct hardware access. If you have device-specific +code left from the above steps, it should be refactored into these callbacks. + +Here is a simple example: + ++static struct watchdog_ops s3c2410wdt_ops = { ++ .owner = THIS_MODULE, ++ .start = s3c2410wdt_start, ++ .stop = s3c2410wdt_stop, ++ .ping = s3c2410wdt_keepalive, ++ .set_timeout = s3c2410wdt_set_heartbeat, ++}; + +A typical function-header change looks like: + +-static void s3c2410wdt_keepalive(void) ++static int s3c2410wdt_keepalive(struct watchdog_device *wdd) + { +... ++ ++ return 0; + } + +... + +- s3c2410wdt_keepalive(); ++ s3c2410wdt_keepalive(&s3c2410_wdd); + + +Add the watchdog device +----------------------- + +Now we need to create a 'struct watchdog_device' and populate it with the +necessary information for the framework. The struct is also explained in detail +in 'watchdog-kernel-api.txt' in this directory. We pass it the mandatory +watchdog_info struct and the newly created watchdog_ops. Often, old drivers +have their own record-keeping for things like bootstatus and timeout using +static variables. Those have to be converted to use the members in +watchdog_device. Note that the timeout values are unsigned int. Some drivers +use signed int, so this has to be converted, too. + +Here is a simple example for a watchdog device: + ++static struct watchdog_device s3c2410_wdd = { ++ .info = &s3c2410_wdt_ident, ++ .ops = &s3c2410wdt_ops, ++}; + + +Register the watchdog device +---------------------------- + +Replace misc_register(&miscdev) with watchdog_register_device(&watchdog_dev). +Make sure the return value gets checked and the error message, if present, +still fits. Also convert the unregister case. + +- ret = misc_register(&s3c2410wdt_miscdev); ++ ret = watchdog_register_device(&s3c2410_wdd); + +... + +- misc_deregister(&s3c2410wdt_miscdev); ++ watchdog_unregister_device(&s3c2410_wdd); + + +Update the Kconfig-entry +------------------------ + +The entry for the driver now needs to select WATCHDOG_CORE: + ++ select WATCHDOG_CORE + + +Create a patch and send it to upstream +-------------------------------------- + +Make sure you understood Documentation/SubmittingPatches and send your patch to +linux-watchdog@vger.kernel.org. We are looking forward to it :) + -- GitLab From 25dc46e3837cd01dc1742eefb73d064f6336850f Mon Sep 17 00:00:00 2001 From: Wolfram Sang <w.sang@pengutronix.de> Date: Mon, 26 Sep 2011 15:40:14 +0200 Subject: [PATCH 1508/1531] watchdog: s3c2410: convert to use the watchdog framework Make this driver a user of the watchdog framework and remove now centrally handled parts.

The concern is that it's getting these definitions via mach/system.h, which is supposed to only be included by arch/arm/kernel/process.c. As this header is scheduled for cleanup (and elimination) keeping the status quo will cause build errors. So lets fix properly and independent of the future work.

For 3.2-rc1, it's safer to revert this check (actually this patch comments out the code). We may re-introduced the fixed version once after the wider test-case coverages are done.

This prevents use of dynamic debugging for out-of-tree modules once the next patch is applied. This condition was apparently intended to avoid a crash if a force- loaded module has an incompatible definition of dynamic debug structures. However, a administrator that forces us to load a module is claiming that it *is* compatible even though it fails our version checks. If they are mistaken, there are any number of ways the module could crash the system. As a side-effect, proprietary and other tainted modules can now use dynamic_debug.
