drm/amdgpu: Create an option to disable soft recovery

2023-09-11T21:22:23Z

Create a module option to disable soft recoveries on amdgpu, making every recovery go through the device reset path. This option makes easier to force device resets for testing and debugging purposes. Signed-off-by: André Almeida Reviewed-by: Christian König Signed-off-by: Hamza Mahfooz Signed-off-by: Alex Deucher

drm/amdgpu: mark soft recovered fences with -ENODATA

drm/amdgpu: Modify indirect buffer packages for resubmission

2023-06-09T16:44:15Z

When the preempted IB frame resubmitted to cp, we need to modify the frame data including: 1. set PRE_RESUME 1 in CONTEXT_CONTROL. 2. use meta data(DE and CE) read from CSA in WRITE_DATA. Add functions to save the location the first time IBs emitted and callback to patch the package when resubmission happens.

And ensure each ring supports that many submissions. This makes sure that we don't get surprises after the submission has been scheduled where the ring allocation actually gets rejected.

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.
