This commit adds a mechanism that checks if a module has VBlank. If the target module has VBlank support, kms_flip will run all the VBlank tests; otherwise, the VBlank tests will be skipped. Additionally, this commit improves the test coverage by checks if the function drmWaitVBlank() returns EOPNOTSUPP (i.e., no VBlank support). V5: Drop the DRM_VBLANK_NEXTONMISS (Chris Wilson) V4: Replace DRM_VBLANK_ABSOLUTE by DRM_VBLANK_RELATIVE and DRM_VBLANK_NEXTONMISS V3: Add documentation (Daniel Vetter) V2: Add new branch coverage to check if VBlank is enabled or not and update commit message V1: Chris Wilson - Change function name from igt_there_is_vblank to kms_has_vblank - Move vblank function check from igt_aux to igt_kms - Utilizes memset in dummy_vbl variable - Directly return the result of drmWaitVBlank() Signed-off-by: Rodrigo Siqueira --- lib/igt_kms.c | 20 ++++++++++++++++++++ lib/igt_kms.h | 2 ++ tests/kms_flip.c | 22 ++++++++++++++++++++++ 3 files changed, 44 insertions(+) diff --git a/lib/igt_kms.c b/lib/igt_kms.c index 43f45997..d3ab3684 100644 --- a/lib/igt_kms.c +++ b/lib/igt_kms.c @@ -1660,6 +1660,26 @@ void igt_assert_plane_visible(int fd, enum pipe pipe, bool visibility) igt_assert_eq(visible, visibility); } +/** + * kms_has_vblank: + * @fd: DRM fd + * + * Get the VBlank errno after an attempt to call drmWaitVBlank().
