68LC040 support....

I was wondering if NetBSD/mac68k had functional support for machines  
with 68LC040's at this point?  I remember hearing some rumblings a  
few years ago it didn't.  I found an old Centris 610 in a closet at  
work.

Thanks,

I've been wondering the same thing.  I acquired a couple of old 
Performas I'd like to play around with, and 33 MHz full-68040s are 
getting hard to find.

Hmm...  I recently ordered one from eBay at around 10 euro and there
were plenty of offers!

Well, grab a NetBSD 5 beta snapshot from ftp.netbsd.org, and try... ISTR,
though, that the recommendated way was to go with a distribution built with
-soft-float, rather than rely on the FPU emulation. The  mailing-list
archives will know more.

Exactly.  The FPU emulator cannot work well with (some of?) the LC
chips due to a hardware bug.  If you build your own release with
MKSOFTFLOAT=yes (pass that to build.sh through -V), you should be
fine.

It'll work, but with lots of core dumps. I'll try to build a full NetBSD-4 
set using -soft-float and see if that's still functional. I'll post the 
results here in case anyone else has FPU-less '040s.

I've made an entire build of NetBSD 4 from today's cvs of the netbsd-4 
branch with a GENERIC kernel for '040s with soft-float. Not sure how 
functional it is, so if you try, please report status. It's available 
here:

ftp.ziaspace.com/pub/NetBSD/mac68k-softfloat/binary/sets/
and
ftp.ziaspace.com/pub/NetBSD/mac68k-softfloat/binary/kernel/

Good luck!

John

Wow, thank you for this!  I'm looking forward to trying it out once I've 
  smashed a few of these systems together to make one good one.

 	Did the set of patches to build softfloat userland ever get
 	imported into the source tree?

If what I remember is correct, it not only got imported, but it got 
imported upstream in the main gcc source, too.
