I have tried it with an 2.6.33-rc7-kernel with these configs:
http://alius.ayous.org/~aba/config-2.6.33-rc7-dsa-mipsel-lemote
http://alius.ayous.org/~aba/config-2.6.33-rc7-dsa-mipsel-lemote.1
This kernel ends at the moment where it displays the registers at the
vga screen. I boot it with:
ifaddr rtl0 ...
load tftp://... no_auto_cmd
g console=tty root=/dev/hda1 no_auto_cmd
(I think at least in the first kernel I missed something obvious,
namely the console. Could be the same issue with the second.)
The machine works with the heavily patched 2.6.31 kernel (which has a
few patches from lemote). However, with that kernel (built with both
new binutils options, used as -Wa,.. and -Wl,...) the machine stops
at always the same step while building binutils in a standard debian
unstable chroot:
make[3]: Entering directory `/build/buildd-binutils_2.20-5~mipselaba.1-mipsel-1AL2Gb/binutils-2.20/builddir-single/libiberty'
if [ x"-fPIC" != x ] && [ ! -d pic ]; then \
mkdir pic; \
else true; fi
touch stamp-picdir
if [ x"-fPIC" != x ]; then \
gcc -c -DHAVE_CONFIG_H -g -O2 -I. -I../../libiberty/../include -W -Wall -Wwrite-strings -Wc++-compat -Wstrict-prototypes -pedantic -fPIC ../../libiberty/regex.c -o pic/regex.o; \
else true; fi
(please see http://buildd.debian.org/ for a full "normal" build log -
this is basically the first time gcc is called for real and not only
to create config.*)
For building any of the kernels, I used -mfix-loongson2f-nop and
-mfix-loongson2f-jump, built with binutils patched with
http://sourceware.org/ml/binutils/2009-11/msg00387.html .
Do I need to use -mfix-ls2f-kernel from
http://archlinux-for-loongson.googlegroups.com/web/binutils-2.19.1-loongson2f-3.patch
as well? I understood it as that patch is already included in the
newer binutils patch.
BTW, If I have to choose, I'd prefer in getting some variant of 2.6.33
running on the machine - the nearer to the linus tree the better. :)
Cheers,
Andi
