From: Chris Wilson Date: Tue, 7 Nov 2017 11:40:51 +0000 (+0000) Subject: drm/i915/selftests: Take rpm wakeref around GGTT lowlevel tests X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c29ccb9f426e6e4e91c9901bb6ee8dbe6abc48eb;p=openwrt%2Fstaging%2Fblogic.git 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.
