drm/amd/amdgpu implement tdr advanced mode

2021-04-09T20:45:45+00:00

[Why] Previous tdr design treats the first job in job_timeout as the bad job. But sometimes a later bad compute job can block a good gfx job and cause an unexpected gfx job timeout because gfx and compute ring share internal GC HW mutually. [How] This patch implements an advanced tdr mode.It involves an additinal synchronous pre-resubmit step(Step0 Resubmit) before normal resubmit step in order to find the real bad job. 1. At Step0 Resubmit stage, it synchronously submits and pends for the first job being signaled. If it gets timeout, we identify it as guilty and do hw reset. After that, we would do the normal resubmit step to resubmit left jobs. 2. For whole gpu reset(vram lost), do resubmit as the old way. v2: squash in build fix (Alex) Signed-off-by: Jack Zhang Reviewed-by: Andrey Grodzovsky Signed-off-by: Alex Deucher

drm/sched: select new rq even if there is only one v3

drm/scheduler: Job timeout handler returns status (v3)

2021-01-29T10:30:22+00:00

This patch does not change current behaviour. The driver's job timeout handler now returns status indicating back to the DRM layer whether the device (GPU) is no longer available, such as after it's been unplugged, or whether all is normal, i.e. current behaviour. All drivers which make use of the drm_sched_backend_ops' .timedout_job() callback have been accordingly renamed and return the would've-been default value of DRM_GPU_SCHED_STAT_NOMINAL to restart the task's timeout timer--this is the old behaviour, and is preserved by this patch. v2: Use enum as the status of a driver's job timeout callback method. v3: Return scheduler/device information, rather than task information.

drm/scheduler: Essentialize the job done callback

2020-12-08T13:38:09+00:00

The job done callback is called from various places, in two ways: in job done role, and as a fence callback role. Essentialize the callback to an atom function to just complete the job, and into a second function as a prototype of fence callback which calls to complete the job. This is used in latter patches by the completion code.

gpu/drm: ring_mirror_list --> pending_list

2020-12-08T13:38:03+00:00

Rename "ring_mirror_list" to "pending_list", to describe what something is, not what it does, how it's used, or how the hardware implements it. This also abstracts the actual hardware implementation, i.e. how the low-level driver communicates with the device it drives, ring, CAM, etc., shouldn't be exposed to DRM. The pending_list keeps jobs submitted, which are out of our control. Usually this means they are pending execution status in hardware, but the latter definition is a more general (inclusive) definition.
