From: Ville Syrjälä Date: Tue, 2 Jun 2015 12:37:36 +0000 (+0300) Subject: drm/i915: Set INSTPM_FORCE_ORDERING via LRI on gen8, drop it on gen9+ X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9cc83020616d38339e6c29dc44536e9806abfdb0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Set INSTPM_FORCE_ORDERING via LRI on gen8, drop it on gen9+ INSTPM is saved in the logical context so we should initialize it using LRIs on gen8. It actually defaults to 1 starting from HSW, but let's keep the write around anyway. Also drop the INSTPM_FORCE_ORDERING setup entirely on gen9+ since it's now a reserved bit.
