drm/amdgpu: Use seq_puts() instead of seq_printf()

2023-07-25T17:47:26+00:00

For a constant format without additional arguments, use seq_puts() instead of seq_printf(). Also, it fixes the following warning. WARNING: Prefer seq_puts to seq_printf And other style fixes: WARNING: Prefer 'unsigned int' to bare use of 'unsigned' WARNING: Block comments should align the * on each line Cc: Christian König Cc: Alex Deucher Signed-off-by: Srinivasan Shanmugam Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: don't require a job for cond_exec and shadow

2023-04-24T22:16:27+00:00

We need to reset the shadow state every time we submit an IB and there needs to be a COND_EXEC packet after the SET_Q_PREEMPTION_MODE packet for it to work properly, so we should emit both of these packets regardless of whether there is a job present or not.

drm/amdgpu: add gfx shadow CS IOCTL support

2023-04-24T22:16:19+00:00

Add support for submitting the shadow update packet when submitting an IB. Needed for MCBP on GFX11. v2: update API for CSA (Alex) v3: fix ordering; SET_Q_PREEMPTION_MODE most come before COND_EXEC Add missing check for AMDGPU_CHUNK_ID_CP_GFX_SHADOW in amdgpu_cs_pass1() Only initialize shadow on first use (Alex) v4: Pass parameters rather than job to new ring callback (Alex) v5: squash in change to call SET_Q_PREEMPTION_MODE/COND_EXEC before RELEASE_MEM to complete the UMDs use of the shadow (Alex) Reviewed-by: Christian König Signed-off-by: Christian König Signed-off-by: Alex Deucher

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

2023-04-14T17:47:49+00:00

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.

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

2022-12-02T15:04:51+00:00

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.
