drm/amdgpu: move vmhub out of amdgpu_ring_funcs (v4)

2023-04-14T17:47:49Z

It looks better to place this field in ring structure. Also drop the repeated ring funcs definitions if there's no difference except for vmhub field. v2: rename the field to vm_hub like others (Le) v3: apply the changes to new ip blocks (Hawking) v4: fix vcn sw ring (Alex) Signed-off-by: Le Ma Reviewed-by: Christian König Reviewed-by: Hawking Zhang Signed-off-by: Hawking Zhang Signed-off-by: Alex Deucher

drm/amd: Convert amdgpu to use suballocation helper.

2023-03-01T16:18:19Z

Now that we have a generic suballocation helper, Use it in amdgpu. For lines that get moved or changed, also fix up pre-existing style issues.

drm/amdgpu: MCBP based on DRM scheduler (v9)

2022-12-02T15:04:51Z

Trigger Mid-Command Buffer Preemption according to the priority of the software rings and the hw fence signalling condition. The muxer saves the locations of the indirect buffer frames from the software ring together with the fence sequence number in its fifo queue, and pops out those records when the fences are signalled. The locations are used to resubmit packages in preemption scenarios by coping the chunks from the software ring. v2: Update comment style. v3: Fix conflict caused by previous modifications. v4: Remove unnecessary prints. v5: Fix corner cases for resubmission cases. v6: Refactor functions for resubmission, calling fence_process in irq handler. v7: Solve conflict for removing amdgpu_sw_ring.c. v8: Add time threshold to judge if preemption request is needed. v9: Correct comment spelling. Set fence emit timestamp before rsu assignment.

drm/amd/amdgpu embed hw_fence into amdgpu_job

2021-08-16T19:16:58Z

Why: Previously hw fence is alloced separately with job. It caused historical lifetime issues and corner cases. The ideal situation is to take fence to manage both job and fence's lifetime, and simplify the design of gpu-scheduler. How: We propose to embed hw_fence into amdgpu_job. 1. We cover the normal job submission by this method. 2. For ib_test, and submit without a parent job keep the legacy way to create a hw fence separately. v2: use AMDGPU_FENCE_FLAG_EMBED_IN_JOB_BIT to show that the fence is embedded in a job. v3: remove redundant variable ring in amdgpu_job v4: add tdr sequence support for this feature. Add a job_run_counter to indicate whether this job is a resubmit job. v5 add missing handling in amdgpu_fence_enable_signaling Signed-off-by: Jingwen Chen Signed-off-by: Jack Zhang Reviewed-by: Andrey Grodzovsky Reviewed by: Monk Liu Signed-off-by: Alex Deucher
