From: Ville Syrjälä Date: Wed, 13 Apr 2016 18:19:56 +0000 (+0300) Subject: drm/i915: Move gt/pm irq handling out from irq disabled section on VLV X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=528948745f6f52f36839b76beeab0632a9f16471;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Move gt/pm irq handling out from irq disabled section on VLV No need to actually handle the GT/PM interrupt while we have interrupt sources disabled. Move the actual processing to happen after we've restored VLV_IER and master interrupt enable.
