[igt-dev] [PATCH i-g-t v4 2/2] tests: Check and skip unhandled tests that needs display

José Roberto de Souza jose.souza at intel.com
Thu Sep 13 20:39:35 UTC 2018


'lib: Require drmModeResources()' take care of all tests that calls
igt_display_init(), here handling other tests that needs display and
do not call it.

v2:
- Not skipping all tests in debugfs_test, perf_pmu and perf_pmu,
now skiping only the required subtests

v3:
- Renamed igt_require_display to igt_display_required, to keep naming
consistent
- Added igt_display_available()
- Checking if display is available by quering a modeset capability
instead of drmModeGetResources()
- Not skiping read_all_entries tests when display is disabled

v4:
- Using 'lib: Require drmModeResources()', so all tests already
handled by that patch had the igt_display_require() call removed.
