2018-07-07drm/i915: Replace nested subclassing with explicit subclassesChris Wilson
In the next patch, we will want a third distinct class of timeline that may overlap with the current pair of client and engine timeline classes. Rather than use the ad hoc markup of SINGLE_DEPTH_NESTING, initialise the different timeline classes with an explicit subclass.

2018-07-07drm/crtc: Add a generic infrastructure to fake VBLANK eventsBoris Brezillon
In some cases CRTCs are active but are not able to generating events, at least not at every frame at it's expected to. This is typically the case when the CRTC is feeding a writeback connector that has no job queued. In this situation the CRTC is usually stopped until a new job is queued, and this can lead to timeouts when part of the pipeline is updated but no new jobs are queued to the active writeback connector. In order to solve that, we add a ->no_vblank flag to drm_crtc_state and ask the CRTC drivers to set it to true when they know they're not able to generate VBLANK events. The core drm_atomic_helper_fake_vblank() helper can then be used to fake VBLANKs at commit time.

2018-07-07drm/vc4: Use wait_for_flip_done() instead of wait_for_vblanks()Boris Brezillon
drm_atomic_helper_wait_for_vblanks() assumes the CRTC will continuously generate VBLANK events and the vblank counter will keep increasing. While this work for a regular pipeline, it doesn't when you have the CRTC is feeding the transposer block, because this block works in oneshot mode, and, by the time we reach drm_atomic_helper_wait_for_vblanks() the only VBLANK event might have already been sent and the VBLANK counter will stay unchanged, thus triggering a timeout. Luckily, we can replace the drm_atomic_helper_wait_for_vblanks() call by drm_atomic_helper_wait_for_flip_done() because the only thing we want to check when calling drm_atomic_helper_wait_for_vblanks() from vc4_atomic_complete_commit() is that new FBs are in use and the old ones can be safely released.

2018-07-06drm/i915: Track the last-active inside the i915_vmaChris Wilson

Let's use this fact to decide if the encoder is active.

2018-07-06drm/i915/selftests: Skip all request selftests when wedgedChris Wilson
If the GPU is irrecoverably wedge, we cannot submit any request and so all of the request selftests will expectedly fail. Skip over them.

2018-07-06drm/i915/selftests: Skip making an object busy if the GPU is wedgedChris Wilson
If the GPU is wedged, we cannot make the object busy as trying to submit a request will generate -EIO. Skip to the end of the test.

2018-07-06drm/i915/selftests: Skip using the GPU if wedgedChris Wilson
If the GPU is irrecoverably broken, we can not use it to dirty memory and check for cache coherency with the CPU. All we can do is simply skip over the GPU subtests and focus on the CPU domains (WC, WB) cache management.

2018-07-06drm/i915/selftests: Destroy partial tiling vma after useChris Wilson
As we keep VMA around until the object is destroyed, when testing partial tiling we instantiate many, many VMA (as the object is huge allowing for many different partial regions). We test elsewhere our handling of populating large objects with a full set of VMA and checking we can retrieve them afterwards, but in this test we incur the cost of flushing all VMA after every GTT write, dramatically slowing down the test.

2018-07-06drm/i915: Squelch very verbose error loggingChris Wilson
Having found the error causing the IGT test to fail, downgrade the verbose logging so that we stop flooding the syslogs as we deliberately provoke it many thousands of time during selftests.
