[Intel-gfx] [PATCH i-g-t v2] tests/kms_concurrent: Concurrent and interruptible subtests for atomic
Mika Kahola
mika.kahola at intel.com
Wed Mar 15 08:43:44 UTC 2017
This test case introduces concurrently running test cases for atomic
modesetting.
The first test or thread draws blue backround with black holes on it.
These holes are covered by rectangular, blue planes that are placed
randomly like in test case 'kms_plane_multiple'.
The second thread changes resolution from higher to lower one and back.
The delay between resolution changes is randomly selected between 20 and
50 milliseconds.
The test runs by default 32 iterations to increase the coverage.
v2: use igt_fork instead of pthreads to create concurrent test runs (Maarten)
