drm/amdgpu/gfx11: set UNORD_DISPATCH in compute MQDs

2024-02-01T00:21:18+00:00

[ Upstream commit 3380fcad2c906872110d31ddf7aa1fdea57f9df6 ]

This needs to be set to 1 to avoid a potential deadlock in
the GC 10.x and newer.  On GC 9.x and older, this needs
to be set to 0. This can lead to hangs in some mixed
graphics and compute workloads. Updated firmware is also
required for AQL.

Revert "drm/amdkfd: Relocate TBA/TMA to opposite side of VM hole"

2024-01-25T23:45:09+00:00

commit 0f35b0a7b8fa402adbffa2565047cdcc4c480153 upstream.

That commit causes NULL pointer dereferences in dmesgs when
running applications using ROCm, including clinfo, blender,
and PyTorch, since v6.6.1. Revert it to fix blender again.

This reverts commit 96c211f1f9ef82183493f4ceed4e347b52849149.

drm/amdkfd: Confirm list is non-empty before utilizing list_first_entry in kfd_topology.c

[ Upstream commit 499839eca34ad62d43025ec0b46b80e77065f6d8 ]

Before using list_first_entry, make sure to check that list is not
empty, if list is empty return -ENODATA.

drm/amdkfd: Fix type of 'dbg_flags' in 'struct kfd_process'

[ Upstream commit 217e85f97031791fb48a2d374c7bdcf439365b21 ]

dbg_flags looks to be defined with incorrect data type; to process
multiple debug flag options, and hence defined dbg_flags as u32.

drm/amdkfd: svm range always mapped flag not working on APU

2023-12-19T20:19:49+00:00

On gfx943 APU there is no VRAM and page migration, queue CWSR area, svm
range with always mapped flag, is not mapped to GPU correctly. This
works fine if retry fault on CWSR area can be recovered, but could cause
deadlock if there is another retry fault recover waiting for CWSR to
finish.

Fix this by mapping svm range with always mapped flag to GPU with ACCESS
attribute if XNACK ON.

There is side effect, because all GPUs have ACCESS attribute by default
on new svm range with XNACK on, the CWSR area will be mapped to all GPUs
after this change. This side effect will be fixed with Thunk change to
set CWSR svm range with ACCESS_IN_PLACE attribute on the GPU that user
queue is created.

drm/amdkfd: Free gang_ctx_bo and wptr_bo in pqm_uninit

2023-11-29T23:12:29+00:00

[Why]
Memory leaks of gang_ctx_bo and wptr_bo.

[How]
Free gang_ctx_bo and wptr_bo in pqm_uninit.

v2: add a common function pqm_clean_queue_resource to
free queue's resources.
v3: reset pdd->pqd.num_gws when destorying GWS queue.
