2.4.10 SMP on powermac3,3 7400. had to hack.

[pjordan]

find /usr/src/linux -type f -exec grep mmu_gathers -n {} \; -ls

and for some funny reason, the arch/ppc/mm/init.c is the only one that does not have the lines 

#include <asm/tlb.h>

mmu_gather_t mmu_gathers[NR_CPUS];


in it.


Sorry for no proper patch.  It is too late and I am too lazy.

Anyway, there is some funny video driver issue or something, I have to use prevent xdm from trying to start
or this bugger will hang .. or at least I lose the video display and the monitor power light blinks on and off.

Also if I run gpm and select a line of text on the console I get the highlighted area turning into
funny non-printable characters and happy faces and such.

Good night.

oh: Without the above patch the kernel build fails right at the end when linking mm.o with others and complains
about no reference to mm_gathers in zap_page_reg or something like that.

Yes, somehow that got missed.

There is a patch that fixes this and other issues at
ftp://ftp.kernel.org/pub/linux/kernel/ports/ppc/ppc-patch-2.4.10.bz2

This patch has the differences between Linus' 2.4.10 and the
linuxppc_2_4 repository.  See http://penguinppc.org/dev/kernel.shtml
for details on how to access this and the other PPC repositories.

Sounds like an X config problem.  I suggest you ask on the
linuxppc-user@lists.linuxppc.org mailing list, you might get more help
there.
