2018-01-15tests/kms_plane: Run test for all supported pixel formats, v2.Mahesh Kumar
This patch adds a subtest related to pixel format testing. The test tries to create framebuffer with all supported pixel formats on every plane, and tries to draw them using cairo and commits the same on display. Changes since v1: - Make the test more generic and try on all planes, including legacy cursor.

2018-01-15tests/perf_pmu: Exercise busy stats and lite-restoreTvrtko Ursulin
While developing a fix for an accounting hole in busy stats we realized lite-restore is a potential edge case which would be interesting to check is properly handled. It is unfortnately quite timing sensitive to hit lite-restore in the fashion test needs, so downside of this test is that it sufferes from a high rate of false negatives. v2: * Make the sleep unconditional and use scientific notiation for large constants.

2018-01-02tests/kms_cursor_legacy: Rework the 2x-*-vs-cursor-* tests.Maarten Lankhorst
Using the fancy new DRM_CAP_CRTC_IN_VBLANK_EVENT cap I can finally make this test the work I originally intended to. For the !modeset case that means performing a pageflip on both crtc's, then requeueing as soon as the event is delivered and then check the vblank counter against the original value, it should be advanced by 1. The modeset case is slightly more complicated, ideally it's handled the same, but if we can't perform a modeset and pageflip at the same time, fall back to queueing both in a single commit, in which case we can say nothing about the vblank counter. There is a small race between flip_done and hw_done, so make flip_nonblocking retry for a second when encountering -EBUSY.

Instead of assuming each subtest cleans up after itself, assume it fails and doesn't. Now that igt_kms can clean up stale events, we can just force each subtest to only clean up its framebuffers, which isn't harmful if it failed. The nonblocking modeset test is removed, this was a workaround only needed for intel because it supported nonblocking commit only for the !modeset case, this has been fixed.
