[PATCH 0/4] Invalidate and flush caches at the beginning of every gfx IB

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patchset introduces AQUIRE_MEM packet submission at the begining of each gfx IB
if requested by user mode client. This is helpful in solving issues with cache coherency
during amdgpu_test and Vulkan CTS tests.


Andrey Grodzovsky (4):
  drm/amdgpu: Add new ring callback to insert memory sync
  drm/amdgpu: Add AQUIRE_MEM PACKET3 fields defintion
  drm/amdgpu: Add mem_sync implementation for all the ASICs.
  drm/amdgpu: Add a UAPI flag for user to call mem_sync
