2019-10-23drm/doc: Drop misleading comment on drm_mode_config_cleanupDaniel Vetter1-2/+0
This is not something we'll fix, because failing to clean up stuff (or doing it in the wrong order) is a driver bug. The offending FIXME goes all the way back to the original modeset merge. We've added a WARN_ON in commit 2b677e8c08eed11e4ebe66a7c334f03e389a19a3 Author: Daniel Vetter <[email protected]> Date: Mon Dec 10 21:16:05 2012 +0100 drm: reference framebuffers which are on the idr including a comment blaming drivers on this. Right thing to do is most likely drm_atomic_helper_shutdown plus making sure that drm_mode_config_cleanup is not called too early (i.e. not in driver unload, but only in the final drm_device release callback).

If retirement is running on another thread, we may inspect the status of the i915_active before its retirement callback is complete. As we expect it to be running synchronously, we can wait for any callback to complete by acquiring the i915_active.mutex.

2019-10-22drm/i915: Drop assertion that ce->pin_mutex guards state updatesChris Wilson4-24/+0
The actual conditions are that we know the GPU is not accessing the context, and we hold a pin on the context image to allow CPU access. We used a fake lock on ce->pin_mutex so that we could try and use lockdep to assert that access is serialised, but the various different hardirq/softirq contexts where we need to *fake* holding the pin_mutex are causing more trouble. Still it would be nice if we did have a way to reassure ourselves that the direct update to the context image is serialised with GPU execution. In the meantime, stop lockdep complaining about false irq inversions.

2019-10-21drm/i915: Don't set queue_priority_hint if we don't kick the submissionChris Wilson1-15/+22
If we change the priority of the active context, then it has no impact on the decision of whether to preempt the active context -- we don't preempt the context with itself. In this situation, we elide the tasklet rescheduling and should *not* be marking up the queue_priority_hint as that may mask a later submission where we decide we don't have to kick the tasklet as a higher priority submission is pending (spoiler alert, it was not).
