The focus of Intel's X.Org driver developers is on getting ready the xf86-video-intel 2.8 driver
for this quarter's update that will remove the EXA acceleration architecture
in favor of UXA acceleration
and it completely strips away the DRI1 support. The Intel X.Org team released the xf86-video-intel 2.7.0 driver
nearly a month ago, but they have cherry-picked a few fixes from their current development efforts to provide a 2.7.1 release.
The xf86-video-intel 2.7.1 driver hooks up RandR properties support under a KMS-enabled environment and also five other bug fixes that hopefully will fix a few crashes and other problems that have come about. This minor update will not, however, fix the widespread performance problems that are well known within their new driver stack. Addressing this will require a larger driver update than a simple point release along with an updated kernel DRM and other changes.
