Enabling amdgpu in llvm80 solved the problem of compiling xorg
on a Pi3b, but now that it's built and installed it still fails
to run.
Running
X -configure as root produces
X Protocol Version 11, Revision 0
Build Operating System: FreeBSD 12.1-STABLE arm64
Current Operating System: FreeBSD nemesis.zefox.com 12.1-STABLE FreeBSD 12.1-STABLE r361020 GENERIC arm64

scfb trace: probe start
No devices to configure. Configuration failed.

The log file looks happy until
[302404.406] (WW) xf86EnableIO: Failed to open /dev/io for extended I/O
[302404.406] (WW) Falling back to old probe method for scfb
[302404.406] scfb trace: probe start
[302404.406] (WW) Falling back to old probe method for modesetting
[302404.406] No devices to configure. Configuration failed.
[302404.407] (EE) Server terminated with error (2). Closing log file.
There is indeed no /dev/io, and I can't find any references to it.
There's a thread at
https://forums.freebsd.org/threads/no-devices-to-configure-configuration-failed.18348/
reporting a smilar failure, but traces the problem to having
kern_securelevel="1", while mine is -1 (evidently the default).
Thanks for reading, any hints appreciated...
