This parameter will allow disabling individual CUs on module load, e.g. amdgpu.disable_cu=2.0.3,2.0.4 to disable CUs 3 and 4 of SE2. Reviewed-by:

On workstation cards with ECC vram, the entirety of vram is cleared to 0 on asic init to set the ECC status correctly. On non ECC boards, I don't think they do any explicit clearing, but the vram controller is reset which may cause issues with the data there. Signed-off-by:

In the AMD powerplay driver, a pointer is checked for validity by comparing against an integer '0', which causes a harmless warning when building with "make W=1": drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/processpptables.c:1502:16: error: ordered comparison of pointer with integer zero [-Werror=extra] This changes the code to the more conventional "if (pointer)" check.

This boosts Xonotic from 38fps to 47fps when artificially limiting VRAM to 256MB for testing. It should improve all CPU bound rendering situations where we have a lot of swapping to/from VRAM. Reviewed-by:

When we pipeline evictions the page directory could already be moving somewhere else when grab_id is called. Reviewed-by:

Free up the memory immediately, remember the last eviction for each domain and make new allocations depend on the last eviction to be completed. Reviewed-by:

As far as I can see no need for a custom implementation any more. Reviewed-by:

Christian König authored
Instead of using the flag just remember the fence of the last move operation. This avoids waiting for command submissions pipelined after the move, but before accessing the BO with the CPU again. Reviewed-by:

It isn't used and not waiting for the GPU after scheduling a move is actually quite dangerous. Reviewed-by:

When we want to pipeline accelerated moves we need to wait in the fallback path. Reviewed-by:

Christian König authored
Wait for idle before moving the BO in all drivers implementing an accelerated move function. This should keep the current behavior when removing the pre move wait. Reviewed-by:

The soft pptable was used for re-uploading pptable as cache, but since previous commits, the generic codes for uploading pptable are used and backend is released during resetting powerplay. So it becomes redundance. Reviewed-by:
