Subject: [PATCH v3 0/4] handle vblank when disabling ctc with interrupt disabled (was [PATCH v2] drm/imx: correct order of crtc disable)
Date: Tue, 25 Jun 2019 18:59:11 +0100 [thread overview]
Message-ID: <cover.1561483965.git.bob.beckett@collabora.com> (raw)
Handle vblank event sent to signal crtc disable while the backend vblank
interrupt has already been disabled by vblank_disable_fn.
Fixes: a474478642d5 ("drm/imx: fix crtc vblank state regression")
Fixes: 68036b08b91bc ("drm/vblank: Do not update vblank count if interrupts are already disabled.")
Fixes: 5f2f911578fb ("drm/imx: atomic phase 3 step 1: Use atomic configuration")
Changes since v2:
Split up the patch in to smaller pieces.
Add warning when about to send bogus vblank event.
Update vblank to best guess info during drm_vblank_disable_and_save.
Robert Beckett (4):
drm/vblank: warn on sending stale event
drm/imx: notify drm core before sending event during crtc disable
drm/vblank: estimate vblank while disabling vblank if interrupt
disabled
drm/imx: only send event on crtc disable if kept disabled
