From 63a3451641ec2e129dfe80044e3c96bc9f0bb690 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Fri, 19 Dec 2014 19:33:25 +0200 Subject: [PATCH] drm/i915: gen9: fix RPS interrupt routing to CPU vs. GT GEN8+ HW has the option to route PM interrupts to either the CPU or to GT. For GEN8 this was already set correctly to routing to CPU, but not for GEN9, so fix this. Note that when disabling RPS interrupts this was set already correctly, though in that case it didn't matter much except for the possibility of spurious interrupts.
