Subject: [PATCH 1/8] drm/irq: Add drm_crtc_send_vblank_event()
Date: Tue, 16 Dec 2014 17:15:08 +0100 [thread overview]
Message-ID: <1418746515-24773-2-git-send-email-thierry.reding@gmail.com> (raw)
In-Reply-To: <1418746515-24773-1-git-send-email-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
This function is the KMS native variant of drm_send_vblank_event(). It
takes a struct drm_crtc * instead of a struct drm_device * and an index
of the CRTC.
Eventually the goal is to access vblank data through the CRTC only so
that the per-CRTC data can be moved to struct drm_crtc.
Signed-off-by: Thierry Reding <treding@nvidia.com>
