From: Boris Brezillon Date: Tue, 3 Jul 2018 09:50:21 +0200 Subject: drm/vc4: Call drm_atomic_helper_fake_vblank() in the commit path Git-commit: 1ebe99a75eeda1067c39c1c039ca9bb7e3c9c342 Patch-mainline: v4.19-rc1 References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166 Mimic what is done in drm_atomic_commit_tail() and call drm_atomic_helper_fake_vblank() so that VBLANK events are faked when the drm_crtc_state.no_vblank is true. Will be needed when we'll add support for the transposer block.
