HI ALL:
   Sorry for crossing post, but I'm quite new here, so if I did
something wrong, please point me the right direction. thanks
   I'm using oe-core, and notice that mipsel support(o32, little
endian mode) is missing (current available choose is: qemumips,
qemumips64, qemumips64el).
   So, here I'm trying to bring up qemumipsel support . My first
attempt would just make qemumipsel work,
further would make it running on real board, thus maybe mips4kec,
mips24k, mips74k chips.
   What I achieved here current:
  1) toolchain/basic libs, utilities should works ,only one changes,
see my patch [a]
   for mipsel we also have to filter out -march=mips32, previously we
only handle mips (the big endian?)
   don't have the error message now, but if you request, I can provide.
  2) attempt to  compile kernel to support qemumipsel, unfortunately it fail.
The point here is linux-yocto doesn't support qemumipsel, but merely
support those other three mips arches,
So here is my attempt patch [b], and the fail log [c], complied out
binary still big endian.

   Could my patch [a] be accepted? or should I send with another mail
for better review?
   Is it better to request a ticket in yocto's bugzilla? or just
report here, I'm not quite sure.

Subject: [PATCH] eglibc: support mipsel little endian, filter out
 -march=mips32

Quote for eglibc source:
 for mips eglibc now builds syscall tables for all abi's
 so we make sure that we choose right march option which is
 compatible with o32,n32 and n64 abi's
 e.g. -march=mips32 is not compatible with n32 and n64 therefore
 we filter it out in such case -march=from-abi which will be
 mips1 when using o32 and mips3 when using n32/n64

I'm quite confident with patch [a], but not sure with patch [b], since
it should point to a sanity SRCREV which works for "qemumipsel" -
little endian side, but here I'm simply duplicate from qemumips (the
big endian port). should confirm?!

Why isn't mipsel getting the mips overrides?  I believe it's meant to.
For what it's worth, mipsel (generically; I haven't tried qemu
specifically) does seem to work fine for me without this patch.

I've always had latent support for mipsel in the kernel tree, since it is
just a minor switch to the configs for the mti.

We'd also sent the KMACHINE to mti-malta32-le to pickup the le
configuration switches from the kernel .. or alternatively, I'll just update
the description to match on qemumipsel.

I'd want to do some build and boot testing myself first though, Phil seemed
to indicate that patch a) wasn't required. I'll start my own build and see if
my results match.

So if there's a desire to get this into oe-core, I can take care of the kernel
tweaks (and then carry it), but I'd expect Richard has an opinion on this, since
it really should be something that we then build and minimally test
on a regular basis.

Cheers,

Bruce

Since it was easy enough to do, and doesn't imply any sort of full
support (since I can't declare that), I did the tweak to the mips
board descriptions and qemumipsel works without any machine mapping
in the linux-yocto recipes.

I pushed the change to the linux-yocto-3.4 meta branch, and staged a
commit for it locally.

You can see that commit here:

http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=zedd/mipsel

  .. stacked on top of my other pending 3.4 commits.

Note: I didn't update machine compatibility in that commit on purpose,
and I wasn't able to complete a full core-image-minimal build due to
QA issues. I'm probably just not building with a complete machine.conf ..
since I grabbed one quickly this morning to check the kernel parts.

Cheers,

Bruce

if you are using 2.15 it uses the compiler to generate syscalls for all abi's
and you should get errors. TARGET_ARCH is in overrides and for mipsel
its set to mipsel and for big endian its mips therefore mips should
not appear in OVERRIDE lists.
I and curious how it worked for you

hi  bruce:
   i'm cherry-pick your commit, and it seems compile successfully, though
will do a run-time check later, thanks
