Chris Wilson 80a9e64f50 uxa: Use temporary dest when target is too large for compositor
If the destination cannot fit into the 3D pipeline when we need to
composite, we fallback to doing the operation on the CPU. This is very
slow, and quite easy to trigger on i915 by plugging in an external
display.

An alternative is to extract the extents of the operation from the
destination using the blitter which can usually handle much larger
operations. This gives us a temporary target that can fit into the 3D
pipeline and thus be accelerated, before copying back into the larger
real destination.

For x11perf this boosts glyph rendering on PineView, from 38kglyphs/s to
480kglyphs/s. Just a little shy of the native performance of 601kglyphs/s

http://www.intellinuxgraphics.com/

What is xf86-video-intel
------------------------
The xf86-video-intel module is an open-source 2D graphics driver for
the X Window System as implemented by X.org. It supports a variety of
Intel graphics chipsets including:

	i810/i810e/i810-dc100,i815,
	i830M,845G,852GM,855GM,865G,
	915G/GM,945G/GM/GME,946GZ
	G/GM/GME/Q965,
	G/Q33,G/Q35,G41,G/Q43,G/GM/Q45
	PineView-M (Atom N400 series)
	PineView-D (Atom D400/D500 series)

Where to get more information about the driver
