From a4d7b30df5d10bca92f8f359fc56fb8db0410f89 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 15 Dec 2014 14:47:18 +0100 Subject: drm/irq: Add drm_crtc_send_vblank_event() 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.
