i've got a lemote desktop with a quad core Loongson-3A in it:
http://www.lemote.com/products/computer/fulong/348.html
i'm trying to build my own kernel for it, but userspace just crashes on me :(.
the current kernel is a precompiled one from lemote themselves, and things are
compiling/running fine with it. but it's a bit stale and missing features i
want (like namespaces & seccomp).
$ uname -a
Linux lemote 3.5.0-9.lemote #1465 SMP PREEMPT Mon Aug 26 14:23:38 CST 2013 mips64 ICT Loongson-3A V0.5 FPU V0.1 lemote-3a-itx-a1101 GNU/Linux
the userland is Gentoo. it's an o32/n32/n64 multilib with n32 as the default.
most (if not all) of userland has been built with gcc-4.8.2 using
"-O2 -march=mips64 -mplt -pipe".

<http://bugs.gentoo.org/>.
i first tried lemote's sources, which i grabbed their git tree from
dev.lemote.com. i started at the same git tag (3.5.0-9.lemote) and used the
same .config as their precompiled kernel. once it booted, most userland progs
would crash. some would survive (like simple ones), but most would crash.
i moved up to vanilla linux-3.18, starting with the same config, but got the
same behavior.
i tried booting with the nofpu command line, but that didn't help. i also
tried manually setting cpu_has_fpu to 0 in
arch/mips/include/asm/mach-loongson/cpu-feature-overrides.h, but that didn't
help.
i tried gcc-4.7.4, gcc-4.8.4, and gcc-4.9.2, but none of that helped.
i enabled the debugging in arch/mips/mm/fault.c, and you can see the attached
dmesg with some of the example crashes. when i looked at proc maps from other
binaries, it looks like those crashing addresses are close to real ones, but
slightly off (like a byte shift?). i'm just guessing since i'm not actually
looking at the crashing app itself ... just assuming the maps are largely stable
(since they seem to be in other ones).
i tried to use strace/gdb to narrow things down, but those both crash early, so
couldn't get anywhere :).
any pointers ?

thanks, but that's kind of dodgy and kind of defeats what i'm going for ;)
- looks like binary-only
- they're x86_64 binaries (i'm doing everything native here, so mips/n32)
- is pretty old (gcc-4.5 / gcc-4.6 / binutils-2.21 / binutils-2.22)
that said, i installed Debian/mipsel(o32) into a chroot. building with the same
sources & configs yielded a kernel that seems to be running OK -- i'm on
mainline linux-3.19 now. it too has an old toolchain: binutils-2.22 and
gcc-4.6.4. i guess there's a miscompilation / the kernel sources have problems
with newer gcc versions.
installing older binutils in Gentoo was pretty easy, but trying to do gcc-4.6
ran into an ICE while bootstrapping. but at least it'll be easy to rule out
weird assembler/linker problems.
might try to put together a script to rebuild the objects one-by-one with the
newer compiler to try and narrow down the problem in the source.

We have also built good kernels with native GCC-4.6.4/4.7.2/4.8.3 (o32
binaries). So maybe this is an N32-related problems.

do you have the source for those versions available ? that way i can see if
there's any patches we should pick up in Gentoo for mips.

that would not surprise me :). we like to push the envelope in Gentoo.

We also built good kernels on N32 Arch-Linux. You can get the source
of GCC/Binutils here:
