+      <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>
