Subject: drm/i915: Update ppgtt_init_ring() & context_enable() to take requests
X-Git-Tag: v4.3-rc1~75^2~36^2~215
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=b3dd6b9681e4116bce4dd1145cb162a5a48bac8e;p=linux.git

drm/i915: Update ppgtt_init_ring() & context_enable() to take requests

The final step in removing the OLR from i915_gem_init_hw() is to pass the newly
allocated request structure in to each step rather than passing a ring
structure. This patch updates both i915_ppgtt_init_ring() and
i915_gem_context_enable() to take request pointers.
