From c29ccb9f426e6e4e91c9901bb6ee8dbe6abc48eb Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 7 Nov 2017 11:40:51 +0000 Subject: [PATCH] drm/i915/selftests: Take rpm wakeref around GGTT lowlevel tests The vma routines are responsible for acquiring the device rpm wakeref before they poke the HW. However, some of the selftests bypass the higher level vma routines in order to poke directly at the lowlevel GGTT functions; these are then responsible for managing rpm themselves.
