drm/amdgpu: track ring state associated with a fence

2025-07-16T20:14:11Z

We need to know the wptr and sequence number associated with a fence so that we can re-emit the unprocessed state after a ring reset. Pre-allocate storage space for the ring buffer contents and add helpers to save off and re-emit the unprocessed state so that it can be re-emitted after the queue is reset.

drm/amdgpu: remove job parameter from amdgpu_fence_emit()

2025-06-30T15:57:06Z

What we actually care about is the amdgpu_fence object so pass that in explicitly to avoid possible mistakes in the future. The job_run_counter handling can be safely removed at this point as we no longer support job resubmission. Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: remove is_mes_queue flag

2025-04-08T20:48:21Z

This was leftover from MES bring up when we had MES user queues in the kernel. It's no longer used so remove it. Acked-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: fix ring timeout issue in gfx10 sr-iov environment

2025-01-24T14:55:04Z

commit 26c95e838e63 ("drm/amdgpu: set the VM pointer to NULL in amdgpu_job_prepare") set job->vm as NULL if there is no fence. It will cause emit switch buffer be skippen if job->vm set as NULL. Check job rather than vm could solve this problem.

drm/amdgpu: cleanup conditional execution

2024-03-04T20:59:08Z

First of all calculating the number of dw to patch into a conditional execution is not something HW generation specific. This is just standard ring buffer calculations. While at it also reduce the BUG_ON() into WARN_ON(). Then instead of a random bit pattern use 0 as default value for the number of dw skipped, this way it's not mandatory any more to patch the conditional execution. And last make the address to check a parameter of the conditional execution instead of getting this from the ring.
