[Spice-devel] [PATCH v2 x11spice 3/4] Initial set of revisions to the dummy driver to add DRI and Present.
Jeremy White
jwhite at codeweavers.com
Wed May 1 16:17:15 UTC 2019
This makes the dummy driver similar to the mode setting driver.
This work was done by Henri Verbeet, which was in turn based heavily on
the Xorg modesetting driver.
