[PATCH] drm/i915: Move intel_vtd_active and run_as_guest to i915_utils
Tvrtko Ursulin
tvrtko.ursulin at linux.intel.com
Mon Mar 28 12:46:15 UTC 2022
From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>
Continuation of the effort to declutter i915_drv.h.
Also, component specific helpers which consult the iommu/virtualization
helpers moved to respective component source/header files as appropriate.
