Intel's Jesse Barnes has today released the xf86-video-intel 188.8.131.52 driver. This is a test release that features integrated GEM memory manager
and kernel-based mode-setting
along with other improvements. The EXA performance should be improved but the video tearing improvements haven't yet been merged. The complete change-log and release announcement can be read on the X.Org mailing list
. The final release of xf86-video-intel 2.5.0 can be expected later this year.
