[PATCH 20/42] Move DGA from extmod to built-in

Daniel Stone daniel at fooishbar.org
Fri Dec 2 03:27:28 PST 2011


Rather than leave DGA languishing in extmod, move it to be a built-in
extension.  As it's quite specific to the Xorg DDX, just move it
sideways to the rest of the DGA code in hw/xfree86/common, and
initialise it from xf86ExtensionInit, rather than miinitext.
