From 7b3c29f6fd374640266d82aafe6929761469e27b Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 10 Jul 2014 20:31:19 +0100 Subject: [PATCH] drm/i915: Make the RPS interrupt generation mask handle the vlv wa We can eliminate a lot of special case code by making the computation of the interrupt mask be correct for all callers.
