Subject: [PATCH i-g-t] tests/kms_rotation_crc: Add vblank wait for multiplane rotation synchronization
Date: Tue, 17 Feb 2026 11:38:25 +0530 [thread overview]
Message-ID: <20260217060825.517098-1-jeevan.b@intel.com> (raw)
Add explicit vblank wait after atomic commit in test_multi_plane_rotation()
to ensure both planes are fully synchronized before CRC capture. This fixes
sporadic CRC mismatches observed on CI.
Closes: https://gitlab.freedesktop.org/drm/xe/kernel/issues/6946
