From 5ea32257d32626251162c5d38f5fbe4af3aca242 Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Fri, 21 Jun 2019 08:07:53 +0100 Subject: [PATCH] drm/i915: Convert i915_gem_init_hw to intel_gt More removal of implicit dev_priv from using old mmio accessors. Actually the top level function remains but is split into a part which writes to i915 and part which operates on intel_gt in order to initialize the hardware. GuC and engines are the only odd ones out remaining.
