makes the screen/keyboard lockup in a mode which suggests the video
mode is mismatched to the screen size, or that some piece of GPU/fb
config data is being scribbled on: I see three or four small copies
of the screen in the top half of the monitor, and the lower half is
a magnified copy of what was on the console, but garbled; there also
appear to be giant letters in the background (larger still than the
lower half text).
Any way to reproduce this?
I note that wscons isn't compiled into GENERIC ... I thought that
was supported in 5.0?
Eh? It's supported since before 3.0 but only got enabled in 5.0. And
it should be in GENERIC.
I am building 5.0_STABLE optimized for supersparc/sun4m right now
(for old, slow systems, I find it's best to eke every cycle you can
out of 'em), and I intend to experiment further with a SPARC Classic
(cg3), and a SunJavastation (Krups, tcx) that I have.
Krups has an IGS1682, not a tcx.
BTW, do we have toolchain cross-compiles working well enough that I
could reliably build an optimized (e.g. CPUFLAGS="-mcpu=supersparc -
mtune=supersparc") on, say, an i386? I have this vague memory of an
issue which made that not work ...
This has been working for ages. COPTS="-mwhatever" is your friend.
