Subject: [PATCH v5 0/2] handle vblank when disabling ctc with interrupt disabled
Date: Fri, 28 Jun 2019 15:15:34 +0100 [thread overview]
Message-ID: <cover.1561729581.git.bob.beckett@collabora.com> (raw)
Add warning when about to send stale vblank.
Revert change that stops vblank info being updated if interrupts already
disabled. This fixes a stale vblank timestamp issue seen on drm/imx.
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.
Changes since v3:
Update cover letter text to describe remaining actions.
Drop drm/imx patches as they have now been merged.
Replace vblank info estimation patch with a revert of the issue that
caused the need for estimation.
Changes since v4:
Updated doc for drm_crtc_send_vblank_event() based on feedback.
Confirmed that htmldoc looks good.

drm/vblank: warn on sending stale event
Revert "drm/vblank: Do not update vblank count if interrupts are
already disabled."
