[Bug 251836] graphics/mesa-dri Intel IRIS

[bugzilla-noreply at freebsd.org]

--- Comment #1 from Jan Beich <jbeich at FreeBSD.org> ---
Which kernel version and GPU is affected? -CURRENT and *lake onward are
well-represented. For example, Iris on Skylake works fine inside 11.4 i386 jail
on -CURRENT amd64 host.

Do you see any errors from kernel, Xorg or Kwin when the hang occurs? Try
running "glxgears -info" to check DRI doesn't silently fall back to llvmpipe
(glitch magnet).

Does installing graphics/mesa-devel help? It doesn't provide llvmpipe, so a GL
app would either use iris/i965 or crash.
