From 82460d97246a993aa49e88bf9b4154cce60f8da8 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 6 Aug 2014 20:19:53 +0200 Subject: [PATCH] drm/i915: Rework ppgtt init to no require an aliasing ppgtt Currently we abuse the aliasing ppgtt to set up the ppgtt support in general. Which is a bit backwards since with full ppgtt we don't ever need the aliasing ppgtt. So untangle this and separate the ppgtt init from the aliasing ppgtt. While at it drag it out of the context enabling (which just does a switch to the default context). Note that we still have the differentiation between synchronous and asynchronous ppgtt setup, but that will soon vanish. So also correctly wire up the return value handling to be prepared for when ->switch_mm drops the synchronous parameter and could start to fail.
