Subject: [PATCH v1 3/6] drm/mediatek: handle events when enabling/disabling crtc
Date: Thu, 28 Nov 2019 10:42:35 +0800 [thread overview]
Message-ID: <20191128024238.9399-4-bibby.hsieh@mediatek.com> (raw)
In-Reply-To: <20191128024238.9399-1-bibby.hsieh@mediatek.com>
The driver currently handles vblank events only when updating planes on
an already enabled CRTC. The atomic update API however allows requesting
an event when enabling or disabling a CRTC. This currently leads to
event objects being leaked in the kernel and to events not being sent
out. Fix it.
