From 795b38b3928d0ad5a6b2a530b30916cc76f4b667 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Wed, 31 Aug 2016 19:13:07 +0300 Subject: [PATCH] drm/i915/bdw: sseu: Fix sseu status parsing Currently when checking for fused off EUs we may ignore the EU count in an enabled slice if there is any disabled slice preceding the enabled one (with a lower slice ID). Perhaps this can't happen in reality, but there is no reason to have this assumption built-in, the code is clearer without it.
