2017-03-21Revert "lib: Open debugfs files for the given DRM device"Tomeu Vizoso
This reverts commit 301ad44cdf1b868b1ab89096721da91fa8541fdc. When a render-only device is opened and gem_quiescent_gpu is called, we need to use the debugfs dir for the master device instead. Signed-off-by: Tomeu Vizoso <tomeu.vizoso@collabora.com>

2017-03-21lib: Open debugfs files for the given DRM deviceTomeu Vizoso
When opening a DRM debugfs file, locate the right path based on the given DRM device FD. This is needed so, in setups with more than one DRM device, any operations on debugfs files affect the expected DRM device. v2: - rebased and fixed new API additions v3: - updated chamelium test, which was missed previously - use the minor of the device for the debugfs path, not the major - have a proper exit handler for calling igt_hpd_storm_reset with the right device fd.

2017-03-20intel-ci: Add initial generic testlistAbdiel Janulgue
Similar to fast-feedback test list. The point of the generic test list is to gather pass-rate when running generic tests - i.e., tests that don't rely on specific GPUs. Again, this test list is dynamic and will either shrink or grow over time.

2017-03-20tests/kms_atomic: test that TEST_ONLY does not clobber stateMika Kahola
We need to make sure that TEST_ONLY really only touches the free-standing state objects and nothing else. Test approach here is the following: - Create a config and submit it with TEST_ONLY. - do dpms off/on cycle with the current config to reconfigure hw - read back all legacy state to make sure none of that is clobbered v2: use ATOMIC_RELAX_NONE instead of CRTC_RELAX_MODE when checking crtc or plane state (Maarten) rename subtest and function that executes this test (Maarten) Signed-off-by: Mika Kahola <mika.kahola@intel.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

2017-03-15tests/kms_cursor_legacy: make_busy() before get_vblank()Ville Syrjälä
VLV is a sloth and so doing anything extra between the first and last get_vblank() is likely to increase the chance of failing the test. Let's move the make_busy() stuff to happen before the first get_vblank() to reduce the amount of work done there. These tests are still failing quite often on my VLV, but that is mostly caused by igt_kms's tendency to still re-read all the connector properties and whatnot as part of the commit operation. I suspect that fixing that would eliminate most of the spurious failures. Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com>

2017-03-13igt/kms_pipe_crc_basic: Tighten timings for CRC readbackChris Wilson

2017-03-13Always expose IGT subtests for known kernel selftestsPetri Latvala
Even when the running kernel does not support selftests, make subtest enumeration list known kselftests. The list is generated using selftest listing headers copied from the kernel.
