From dfabbcb4f6a277992037fe199bcc1bf6bd44a996 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Mon, 4 Jun 2012 14:42:51 -0700 Subject: [PATCH] drm/i915: use the default context With the code to do HW context switches in place have the driver load the default context for the render ring when the driver loads. The default context will be an ever present context that is available to switch to at any time for the given ring.
