Subject: [PATCH] drm/amdgpu: limit the amdgpu_vm_update_ptes trace point
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The text output should not be more than a page, so only print the first
32 page table entries.
If we need all of them we can still look into the binary trace.
