Hi

Sorry I mixed up the versions. 4.16 works ok-ish on my 2200G, 4.17 does
not. The error I'm getting is reported upstream
https://bugs.freedesktop.org/show_bug.cgi?id=106225

The things you patched are all being committed to HEAD this week so it
should build without patches by next week.

We usually keep a temporary WIP branch for new KPI until we get things
committed to HEAD. If you want to build branches newer than drm-devel-kmod,
it's likely that you also need our patched HEAD
https://github.com/FreeBSDDesktop/freebsd-base/tree/drm-vX.YY

I can't tell what's wrong with your system anymore than the log

Nov 19 17:06:08 vega kernel: [drm] Cannot find any crtc or sizes

Best bet, try 4.18 before spending more time one this. It should be
ready later this week.
