--- Comment #13 from Peter Jeremy <peterj@FreeBSD.org> ---
I've just run into the problem highlighted here but (as per comment 8 and
later) on armv7 and the following relates to armv7.

My initial comment: This bug was raised for arm64 and has fixed the issue
there.  Should the armv7 issue be raised as a different bug?

Having looked at hw/xfree86/os-support/bsd/arm_video.c, my initial thought =
was
that Clang defines __arm__, whereas the arm_video.c code is testing for
__arm32__ but manually defining __arm32__ means arm_video.c doesn't compile
because ExtendedEnabled is undefined (it's "static" in
hw/xfree86/os-support/bsd/i386_video.c and
hw/xfree86/os-support/linux/lnx_video.c so this suggests that the code has =
been
cut-and-pasted without ever testing it).

Looking more closely, arm_video.c provides two implementations of
xf86EnableIO() and xf86DisableIO() - one uses /dev/io and the other uses
/dev/ttyC0 - neither of which are present on either FreeBSD armv7 or arm64.=

Adding "or host_machine.cpu_family() =3D=3D 'arm'" to potch-include_meson.b=
uild
resulted in a functional xorg server for me.
