<p>On the kernel side, the Radeon KMS driver was merged in
<tt>stable/9</tt> and will be available in &os; 9.3-RELEASE.
Now both the 9.x and 10.x branches share the same support for
Intel and AMD GPUs.</p>
<p>The next big tasks are the updates of the DRM generic code and
the <tt>i915</tt> driver. Both are making good progress and the
DRM update should hopefully be ready for wider testing during
April. An update of the Radeon driver is on the to-do list, but
nothing is scheduled yet.</p>
<p>On the ports tree and packages side, the update to Cairo 1.12
mentioned in the last quarterly report is ready to be committed,
as people who tested it either reported improvements or no
regressions. As a reminder, the switch from Cairo 1.10 to 1.12
causes display artifacts with xf86-video-intel 2.7.1, but fixes
similar problems with other hardware/driver combinations.
Furthermore, Cairo 1.12 is required by Pango 1.36.0, GTK+ 3.10
and Firefox 27.0. A <q>Heads up</q> mail will be posted to the
<tt>freebsd-x11</tt> mailing-list when this update goes
live.</p>
<p>In the graphics stack's ports development tree, new Mesa ports
are being worked on. Those ports are required to support GLAMOR
(the GL-based 2D acceleration library used by Radeon HD 7000+
cards for instance) and OpenCL (using the GPU to perform
non-graphical calculations). We were able to execute some
"Hello World" OpenCL programs and play with OpenCL in darktable,
but there are some compatibility issues between Clover (Mesa's
libOpenCL implementation) and Clang/<tt>libc++</tt>.</p>
<p>We are preparing an alternate <tt>pkg(8)</tt> repository with
packages built with <tt>WITH_NEW_XORG</tt>. The goal is to ease
the usage of the KMS drivers and move forward with the graphics
stack updates. The main <tt>pkg(8)</tt> repository will still
use the default setting (<tt>WITH_NEW_XORG</tt> set on
<tt>head</tt>, but not on the <tt>stable</tt> branches).</p>
<p>This will pave the way to <tt>WITH_NEW_XORG</tt> deprecation
and the removal of the older stack. The current plan is to do
this after 10.0-RELEASE End-of-Life, scheduled on January 31st,
2015. By that time, the only supported releases will be
8.4-RELEASE, 9.3-RELEASE and 10.1-RELEASE. &os; 9.3 and 10.1
will be fully equipped to work with the newer stack.
Unfortunately, &os; 8.x misses the required kernel DRM
infrastructure: supporting X.Org here cripples progress on the
graphics stack and, once <tt>WITH_NEW_XORG</tt> is gone, we will
not support 8.x as a desktop anymore. Therefore, please upgrade
to 9.3 or 10.1 when they are available.</p>
