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.
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
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.
