<p>All Intel GPUs up to and including the unreleased Kaby Lake
are supported. The <tt>xf86-video-intel</tt> driver will be
updated soon. Updating this driver requires updating
<tt>Xorg</tt>, which in turn is blocked on Nvidia updates.</p>
<p>Several problems remain to be solved:</p>
<ul>
<li>There are instances of visual artifacts that appear with
varying frequency, depending on workload. Of particular
note is lack of redraw when a Qt5 window is partially
covered by a menu and then uncovered.</li>
<li>WebGL demos will sometimes fail due to a recoverable
render ring hang.</li>
<li>There are still some known stability issues with
processors prior to Sandy Bridge (pre-2010).</li>
</ul>
<p>I am hoping to be able to diagnose the first two issues,
along with others, by updating Linux support to the point
where the Intel GPU Tools work on &os;.</p>
<p>The Radeon AMD/ATI has been updated to GCN 1.0. This has
only been tested on an R7 240. 2D-accelerated X works. Due
to apparent issues with user library support, X does not
recognize the KMS driver as being 3D-capable and reports it as
"not DRI2 capable". The OpenCL benchmark <tt>clpeak</tt>
fails in <tt>drm/ttm</tt>, so there may in fact be issues in
the underlying 3D support.</p>
<p>The AMD/ATI driver has been updated to GCN 1.1 and higher.
The KMS driver loads and attaches on discrete GPUs, though
problems still exist on the Carizzo APU. X will not start due
to unimplemented functions in <tt>libdrm</tt>. Koop Mast is
actively working on this and should have it fixed soon.</p>
<p>None of the required patches to <tt>src/sys</tt> were
committed in time for &os; 11. Although the plan is to
ultimately make <tt>linuxkpi</tt>, <tt>drm</tt>,
<tt>i915</tt>, <tt>radeon</tt>, and <tt>amdgpu</tt> updates
available as ports, this will likely not happen until
development has slowed to the point where it is economical to
backport them to &os; in svn. Until that time, modern GPU
support will be available in PC-BSD snapshots and in the
<tt>drm-next-4.6</tt> branch on GitHub.</p>
