Pull drm updates from Dave Airlie: "The usual lots of work all over the place. i915 has gotten some Alderlake work and prelim DG1 code, along with a major locking rework over the GEM code, and brings back the property of timing out long running jobs using a watchdog. amdgpu has some Alderbran support (new GPU), freesync HDMI support along with a lot other fixes.

drm/lima: fix reference leak in lima_pm_busy

2021-02-09T16:14:11+00:00

pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in a reference leak here. A new function pm_runtime_resume_and_get is introduced in [0] to keep usage counter balanced. So We fix the reference leak by replacing it with new function.

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

2021-02-09T16:14:11+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/lima: add governor data with pre-defined thresholds

2021-02-07T12:55:08+00:00

This patch adapts the panfrost pre-defined thresholds change [0] to the lima driver to improve real-world performance. The upthreshold value has been set to ramp GPU frequency to max freq faster (compared to panfrost) to compensate for the lower overall performance of utgard devices.
