drm/amdkfd: add proper handling for S0ix

2025-09-18T18:59:24Z

When in S0i3, the GFX state is retained, so all we need to do is stop the runlist so GFX can enter gfxoff. Reviewed-by: Mario Limonciello (AMD) Tested-by: David Perry Signed-off-by: Alex Deucher (cherry picked from commit 4bfa8609934dbf39bbe6e75b4f971469384b50b1) Cc: stable@vger.kernel.org

drm/amdkfd: Move the process suspend and resume out of full access

2025-06-18T16:19:19Z

For the suspend and resume process, exclusive access is not required. Therefore, it can be moved out of the full access section to reduce the duration of exclusive access. v3: Move suspend processes before hardware fini. Remove twice call for bare metal. v4: Refine code Signed-off-by: Emily Deng Acked-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amdkfd: allow compute partition mode switch with cgroup exclusions

2025-06-18T16:19:17Z

The KFD currently bars a compute partition mode switch while a KFD process exists. Since cgroup excluded devices remain excluded for the lifetime of a KFD process and user space is able to mode switch single devices, allow users to mode switch a device with any running process that has been cgroup excluded from this device.

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/sched: Store the drm client_id in drm_sched_fence

2025-05-28T14:15:58Z

This will be used in a later commit to trace the drm client_id in some of the gpu_scheduler trace events. This requires changing all the users of drm_sched_job_init to add an extra parameter. The newly added drm_client_id field in the drm_sched_fence is a bit of a duplicate of the owner one. One suggestion I received was to merge those 2 fields - this can't be done right now as amdgpu uses some special values (AMDGPU_FENCE_OWNER_*) that can't really be translated into a client id. Christian is working on getting rid of those; when it's done we should be able to squash owner/drm_client_id together.

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.
