Please help - need a 4600 no L2 cache kernel asap

Please help - need a 4600 no L2 cache kernel asap

[Andrew O'Brien]

A Happy New Year to you all !

Anybody there who has a 4600 _without_ a L2 cache or who has a fairly
stable source tree and feels like sparing a few CPU cycles for a kernel
compile, this would be much appreciated if you could send me the binary
kernel.

I need to do some benchmarking on a SGI/Linux platform (an INDY) and I
haven't been able to set up the cross-compilation environment correctly
due to many factors. The benchmarks are needed by mid next week, so this
is a kinda urgent call for help :) 

There is no non-standard bits and pieces - it just need the standard scsi,
ethernet, and serial drivers. Attached is a config file for version 2.1.74
if anybody needs it.

Again, thanks for your help and I hope (and pray ;) to hear from someone
soon.

cya

Is there any reason the binaries on ftp.linux.sgi.com won't work?

Yep - they were compiled assuming that a L2 cache was present - hence when
it tries to flush the cache during init, the system hangs horribly.

I wasn't the only one to be hit by this so I'm sure there is a binary
floating around somewhere :)

Ralf discovered and corrected this in his kernel source after several of us had
problems with his last publicly-available Indy kernel binary (8 December).
 Since then no kernel binary or source has been posted to ftp.linux.sgi.com
(except linux-magnum-971229.tar.gz on 29 December).  Maybe the fix is part of
what Ralf wanted help with before Christmas.

Important change to the SGI/Linux FTP site:

I just moved the CVS source tree hierarchy so it can be
accessed via ftp:

	ftp://ftp.linux.sgi.com/cvs/

There's also a link from the web site to this (software page)
	http://www.linux.sgi.com/software.html

This should enable anyone to compile a good kernel from scratch.

Whoever has a stable kernel that works on a L2-cache-less 4600
please share.  I'll gladly give this person ssh access to linus.

Peace, Ariel

I've fixed the problem and a couple cache thingies before xmas.  Will
upload asap.
