Copy the approach taken by gfx8, which simplifies the code, and set the instance index properly. The latter is required for debugging, e.g. for reading wave status by UMR. Signed-off-by:

We need to wait with the correct owner on unmap operations or otherwise can run into VM faults. Also always wait for the page directory since this is where the reservation object comes from. So rename the function to amdgpu_vm_wait_pd instead as well. Signed-off-by:

This is just future proofing code, not something that can be triggered in real life. We're testing to make sure we don't shift wrap when we do "1ull << i" so "i" has to be in the 0-63 range. If it's 64 then we have gone too far. Acked-by:

A subset of VM fault types currently send retry XNACK to the client. This causes a storm of interrupts from the VM to the host. Until the storm is throttled by other means send no-retry XNACK for all fault types instead. No change in behavior to the client which will stall indefinitely with the current configuration in any case. Improves system stability under GC or MMHUB faults. Signed-off-by:

For GFX context, the ATC bit in SDMA*_GFX_VIRTUAL_ADDRESS can be cleared to perform in VM mode. For RLC context, to support ATC mode , ATC bit in SDMA*_RLC*_VIRTUAL_ADDRESS should be set. SDMA_CNTL.ATC_L1_ENABLE bit is global setting that enables the L1-L2 translation for ATC address. Signed-off-by:

This gives BOs which haven't been accessed by the CPU since they were moved to visible VRAM another chance to stay in VRAM when another BO needs to go to visible VRAM. This should allow BOs to stay in VRAM longer in some cases. v2: * Only do this for BOs which don't have the AMDGPU_GEM_CREATE_CPU_ACCESS_REQUIRED flag set. Reviewed-by:

There is no need for page faults to force BOs into visible VRAM if it's full, and the time it takes to do so is great enough to cause noticeable stuttering. Add GTT as a possible placement so that if visible VRAM is full, page faults move BOs to GTT instead of evicting other BOs from VRAM. Suggested-by:

When a BO is moved to VRAM, clear AMDGPU_GEM_CREATE_CPU_ACCESS_REQUIRED. This allows it to potentially later move to invisible VRAM if the CPU does not access it again. Setting the CPU_ACCESS flag in amdgpu_bo_fault_reserve_notify() also means that we can remove the loop to restrict lpfn to the end of visible VRAM, because amdgpu_ttm_placement_init() will do it for us. v3 [Michel Dänzer] * Use AMDGPU_GEM_CREATE_CPU_ACCESS_REQUIRED instead of a new flag (Christian König) * Clear flag in amdgpu_bo_move instead of amdgpu_move_ram_vram (Christian) * Explicitly mention amdgpu_bo_fault_reserve_notify in amdgpu_bo_move * Also clear flag in amdgpu_bo_create_restricted Suggested-by:

The BO move throttling code is designed to allow VRAM to fill quickly if it is relatively empty. However, this does not take into account situations where the visible VRAM is smaller than total VRAM, and total VRAM may not be close to full but the visible VRAM segment is under pressure. In such situations, visible VRAM would experience unrestricted swapping and performance would drop. Add a separate counter specifically for moves involving visible VRAM, and check it before moving BOs there. v2: Only perform calculations for separate counter if visible VRAM is smaller than total VRAM. (Michel Dänzer) v3: [Michel Dänzer] * Use BO's location rather than the AMDGPU_GEM_CREATE_CPU_ACCESS_REQUIRED flag to determine whether to account a move for visible VRAM in most cases. * Use a single if (adev->mc.visible_vram_size < adev->mc.real_vram_size) { block in amdgpu_cs_get_threshold_for_moves.
