From 59f57847e78d50c1a75830fbe91cfb46bebb93b2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 27 Sep 2018 22:29:08 +0300 Subject: [PATCH] drm/i915: Restore vblank interrupts earlier MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Plane sanitation needs vblank interrups (on account of CxSR disable). So let's restore vblank interrupts earlier.
