So far it doesn't look like that helps. It took a bit longer to crash,
and the screen flashed a pleasing pinkish-maroon before the system
locked up. I'm going to keep trying to fiddle driver section values, but
I think there's something architecturally wrong/missing.
Here's what I've noticed:
we have htole16 and htole32 wrapped around drm read and write functions,
which neither netbsd nor openbsd have (perhaps they wrap it elsewhere).
drm_read8 and drm_write8 on freebsd are not wrapped, which seems odd to
me? I can understand all or none, but "some" seems like 8-bit reads and
writes are either going to be the only ones that work or the only ones
When I try to start X, I am also seeing this mess (X -configure as well)
with WITH_NEW_XORG. I have hw.ofwfb.relax_mmap=1.
