drm/amdkfd: Map wptr BO to GART unconditionally

2025-05-29T14:58:44Z

For simulation C models that don't run CP FW where adev->mes.sched_version is not populated correctly. This causes NULL dereference in amdgpu_amdkfd_free_gtt_mem(dev->adev, (void **)&pqn->q->wptr_bo_gart) and warning on unpinned BO in amdgpu_bo_gpu_offset(q->properties.wptr_bo). Compared with adding version check here and there, always map wptr BO to GART simplifies things. v2: Add NULL check in amdgpu_amdkfd_free_gtt_mem.(Philip) Signed-off-by: Lang Yu Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: add a new flag to manage where VRAM allocations go

2025-02-13T02:04:08Z

On big and small APUs we send KFD VRAM allocations to GTT since the carve out is either non-existent or relatively small. However, if someone sets the carve out size to be relatively large, we may end up using GTT rather than VRAM. No change of logic with this patch, but it allows the driver to determine which logic to use based on the carve out size in the future. Reviewed-by: Mario Limonciello Signed-off-by: Alex Deucher

Pull drm updates from Dave Airlie: "There are two external interactions of note, the msm tree pull in some opp tree, hopefully the opp tree arrives from the same git tree however it normally does. There is also a new cgroup controller for device memory, that is used by drm, so is merging through my tree. This will hopefully help open up gpu cgroup usage a bit more and move us forward.

This partially reverts commit 194eb174cbe4fe2b3376ac30acca2dc8c8beca00. This commit introduced a new state variable into adev without even remotely worrying about CPU barriers.

drm/amdgpu: Fix map/unmap queue logic

2024-11-08T16:10:00Z

In current logic, it calls ring_alloc followed by a ring_test. ring_test in turn will call another ring_alloc. This is illegal usage as a ring_alloc is expected to be closed properly with a ring_commit. Change to commit the map/unmap queue packet first followed by a ring_test. Add a comment about the usage of ring_test. Also, reorder the current pre-condition checks of job hang or kiq ring scheduler not ready. Without them being met, it is not useful to attempt ring or memory allocations. Fixes tag refers to the original patch which introduced this issue which then got carried over into newer code.
