From f24eeb191229b040deb3e813913e06a4316c6d3f Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Fri, 19 Dec 2014 19:33:27 +0200 Subject: [PATCH] drm/i915: vlv: sanitize RPS interrupt mask during GPU idling We apply the RPS interrupt workaround on VLV everywhere except when writing the mask directly during idling the GPU. For consistency do this also there. While at it also extend the code comment about affected platforms. I couldn't reproduce the issue on VLV fixed by this workaround, by removing the workaround from everywhere, while it's 100% reproducible on SNB using igt/gem_reset_stats/ban-ctx-render. So also add a note that it hasn't been verified if the workaround really applies to VLV/CHV.
