We are already doing this for DMA-buf imports and also for
amdgpu VM BOs for quite a while now.
If this doesn't run into any problems we are probably going
to stop removing BOs from the LRU altogether.
v2: drop BUG_ON from ttm_bo_add_to_lru

When a signal arrives we should return immediately for
handling it and not try other placements first.

If drivers don't prefer a system memory placement
they should not but it into the placement list first.

We tried this once before, but that turned out to be more
complicated than thought. With all the right prerequisites
it looks like we can do this now.

Move BOs which are currently in a lower domain to the new
LRU before allocating backing space while validating.
This makes sure that we always have enough entries on the
LRU to allow for other processes to wait for an operation
to complete.
v2: generalize the test
v3: fix rebase error

BOs on the LRU might be blocked during command submission
and cause OOM situations.
Avoid this by blocking for the first busy BO not locked by
the same ticket as the BO we are searching space for.
v10: completely start over with the patch since we didn't
handled a whole bunch of corner cases.

The messages about amdgpu_cs_list_validate are duplicated because the
caller will complain into the logs as well and we can also get

Also fix the the caller to not report -EAGAIN from validation.

And only move them in on validation. This allows for better control
when multiple processes are fighting over those resources.

Well that would allow concurrent calls of
amdgpu_amdkfd_gpuvm_restore_process_bos() to wait for each other.
If that's what you want then yeah that certainly makes sense.

OK, let me rephrase that to make sure I understand it correctly. I think
the point is that eviction candidates come from an LRU list, so leaving
things on the LRU makes more BOs available for eviction and avoids OOM
situations. To take advantage of that, patch 6 adds the ability to wait
for reserved BOs when there is nothing easier to evict.
ROCm applications like to use lots of memory. So it probably makes sense
for us to stop removing our BOs from the LRU as well while we
mass-validate our BOs in amdgpu_amdkfd_gpuvm_restore_process_bos.

Felix

Leaving BOs on the LRU is harmless. We always did this for VM page table
and per VM BOs.
The key point is that BOs which couldn't be reserved can't be evicted.
So what happened is that an application used basically all of VRAM
during CS and because of this X server couldn't pin a BO for scanout.
Now we keep the BOs on the LRU and modify TTM to block for the CS to
complete, which in turn allows the X server to pin its BO for scanout.
Christian.

Hi, Christian
Thanks for you patch .Those patches can fix amdgpu bo pinned failed issue during perform dm_plane_helper_prepare_fb
and Abaqus performance seems improved.
But there some error message can be observer. Do we need drop amdgpu_vm_validate_pt_bos() error message
and other warning debug info .

Can you explain how this avoids OOM situations? When is it safe to leave
a reserved BO on the LRU list? Could we do the same thing in
amdgpu_amdkfd_gpuvm.c? And if we did, what would be the expected side
effects or consequences?
Thanks,
Felix
