From d1ccbb5d711ba4994eb36c4aac84e0269b5365fe Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Wed, 31 Jul 2013 17:00:05 -0700 Subject: [PATCH] drm/i915: make reset&hangcheck code VM aware Hangcheck, and some of the recent reset code for guilty batches need to know which address space the object was in at the time of a hangcheck. This is because we use offsets in the (PP|G)GTT to determine this information, and those offsets can differ depending on which VM they are bound into. Since we still only have 1 VM ever, this code shouldn't yet have any impact.
