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> + </body> + </project> </report>
