From 56c05de6bd773b96deca379370965c49042b5fbf Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 17 Sep 2019 20:47:46 +0100 Subject: drm/i915: Extend Haswell GT1 PSMI workaround to all A few times in CI, we have detected a GPU hang on our Haswell GT2 systems with the characteristic IPEHR of 0x780c0000. When the PSMI w/a was first introducted, it was applied to all Haswell, but later on we found an erratum that supposedly restricted the issue to GT1 and so constrained it only be applied on GT1. That may have been a mistake...
