I tried dropping in the new improved version from linux-2.4.0-test7-pre4,
and none of the 8xx mods are in there: it'l only work for 32 byte cache
lines.

That's not right. Which version of linux-2.4.0-x do you have? I'm sure Paul's,
Cort's and and I know for sure mine work for more than 32 byte cache lines
because 2 of my boxes have 128 byte cache lines and there's support in there
for it. (Paul wrote it... awesome stuff)

I'm talking about linux-2.4.0-test7-pre4, from:
    http://www.kernel.org/pub/linux/kernel/v2.4/linux-2.4.0-test6.tar.bz2
plus:
    http://www.kernel.org/pub/linux/kernel/testing/test7-pre4.gz

  Ah! That's why....

  ftp.kernel.org generally lags behind the PowerPC development tree. For the
latest there are a few sources to choose from. Generally the differences are
based on what people are working on.

  Cort's Tree: www.fsmlabs.com/linuxppcbk.html
  Paul's Tree: linuxcare.com.au/paulus/kernels.html
  My Tree: fsmlabs.com/~tgall

  Take a look at http://linuxppc.org ... very good collection of PowerPC info...

Yes, in sysdeps/powerpc/memset.S.  This is easily enough solved by nuking it,
and allowing glibc to use the generic C version.

Yes, exactly.

It sounds like a few people have at least had a shot at adding support
for other than 32 byte cache lines, but none have propagated into the
official kernels; how does that happen anyway?

By official are you meaning Linus' ?

Yes.  Do I need to run BitKeeper to keep up with the latest ppc changes?
They don't seem to be making it in to Linus's kernel...

I wouldn't say you *NEED* to run BK, as rsync works just fine.

Regards,

Tom
