All Intel GPUs up to and including the unreleased Kaby Lake + are supported. The xf86-video-intel driver will be + updated soon. Updating this driver requires updating + Xorg, which in turn is blocked on Nvidia updates.

+ +

Several problems remain to be solved:

+ +

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.
WebGL demos will sometimes fail due to a recoverable + render ring hang.
There are still some known stability issues with + processors prior to Sandy Bridge (pre-2010).

+ +

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;.

+ +

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 clpeak + fails in drm/ttm, so there may in fact be issues in + the underlying 3D support.

+ +

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 libdrm. Koop Mast is + actively working on this and should have it fixed soon.

+ +

None of the required patches to src/sys were + committed in time for &os; 11. Although the plan is to + ultimately make linuxkpi, drm, + i915, radeon, and amdgpu 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 + drm-next-4.6 branch on GitHub.
