Subject: [PATCH v2 3/4] drm/cirrus: Let DRM core send VBLANK events
Date: Wed, 15 Jan 2020 13:52:25 +0100 [thread overview]
Message-ID: <20200115125226.13843-4-tzimmermann@suse.de> (raw)
In-Reply-To: <20200115125226.13843-1-tzimmermann@suse.de>
In drm_atomic_helper_fake_vblank(), the DRM core sends out VBLANK
events if struct drm_crtc_state.no_vblank is enabled. Replace cirrus'
VBLANK events with the DRM core's functionality.
v2:
* set struct_drm_crtc_state.no_vblank in cirrus_pipe_check()
