commit a31d73c3a7218539bc25fc298ac6cd5b66d96b86 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sun Dec 17 13:28:50 2017 +0000 drm/i915: Re-enable GGTT earlier after GPU reset Inside i915_gem_reset(), we start touching the HW and so require the low-level HW to be re-enabled, in particular the PCI BARs.
