[Intel-gfx] [PATCH i-g-t v3 2/2] kms_content_protection: Add Content Protection test

Sean Paul seanpaul at chromium.org
Mon Jan 8 15:55:21 UTC 2018


Pretty simple test:
- initializes the output
- clears the content protection property
- verifies that it clears
- sets the content protection property to desired
- verifies that it transitions to enabled

Does this for both legacy and atomic.

Changes in v2:
- Don't check for i915 gen
- Skip test if Content Protection property is absent
Changes in v3:
- s/igt_require_f/igt_assert_f/ (Ram)
- Clear property after test runs (Ram)
- s/drm_open_driver/drm_open_driver_master/ (Ram)
- Fix spelling mistake in log message
- Pull out property set/check into helper
