[PATCH xf86-video-r128] Add EXA support
Connor Behan
connor.behan at gmail.com
Thu Jul 12 13:50:00 PDT 2012
This introduces EXA acceleration which can improve performance and
allow 2D acceleration to be used without XAA. Implemented hooks are
Solid, Copy and Composite. They appear to pass all rendercheck tests,
except the gradient test which XAA also fails. Tested on multiple color
depths, with and without DRI, with and without the composite extension.
Hardware cursor, Xvideo and page flipping are supported as well.
Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=47866
