2019-04-10igt: tests: kms_vblank: Stop using magic valueStanislav Lisovskiy
Lot of tests fail, when assertion checking how many vblanks should have passed during suspend/resume is compared to magic value 150. At the same time even for failed cases, sometimes it is clearly visible that there were no issue - simply suspend took longer on that machine. If suspend took around 10 s and we get roughly 60 vblanks per second the value then should be around 600 and not 150. This change removes 150 magic value and starts to use calculation of what it is expected to be instead of being hardcoded. v2: Add possible error delta interval, where expected vblanks must lie, i.e: [estimated_vblanks - err, estimated_vblanks + err] v3: Made an error range for estimated vblanks a bit less strict.

2018-10-01igt: Require a display (KMS enabled) for KMS testsChris Wilson
Simple rule of thumb, if a kms_* test calls igt_display_init() in its global fixture, skip the entire test if the driver has disabled KMS. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Acked-by: Antonio Argenziano <antonio.argenziano@intel.com>

2018-08-31tests/kms_vblank: Test if we have functional rpm before testingChris Wilson
We want to test that provoking a vblank interrupt works correctly after waking up from runtime-pm. First though, we must wait for the device to enter runtime-suspend. If the device cannot, e.g. we haven't enabled the DMC firmware, the test should skip because our external requirements are not met.

2018-02-05tests/kms_vblank: Fix spurious test failure.Maarten Lankhorst
igt_system_suspend_autoresume() calls igt_require(), which isn't allowed to be called from a forked child. Run subtests directly from the test body, except when a forked test is requested.

2018-01-24tests/kms_flip: Move kms_flip.vblank-vs-hang to kms_vblank, v4.Maarten Lankhorst
There's no need to test this more than once. Add a NOHANG flag which can be used to specify that a subtest can not be run when hanging. If it's set on either the subtest or the mode, the -hang test for this combination will not be generated. Changes since v1: - Merge the patch that renamed HANG to NOHANG. - Rebase after 'reorganize subtests by type'. - Allow subtests to specify NOHANG too. Changes since v2: - Mark accuracy test with NOHANG, gpu reset disables interrupts, causing the test to fail. Changes since v3: - Rebase on top of subtest split changes. - Add nohang comment to accuracy test.

2017-12-08tests/kms_vblank: Add test to ensure DRM_CAP_CRTC_IN_VBLANK_EVENT works ↵Maarten Lankhorst
correctly This was implemented correctly only on the atomic ioctl before, but it should really be working on all 3 ioctl's involved, so ensure we always set crtc_id correctly with a testcase. The following events are tested: - Pageflip with event. - Atomic commit with event. - wait_vblank ioctl with event.
