[yocto] linux 3.8

2013-03-01 Thread Trevor Woerner
Given that Greg KH has publicly stated linux-3.8 is not a long term
stable kernel, is it worth the effort to support it in Yocto?

We don't need LTSI to make a kernel worth supporting. We pick our
kernels based on the timing of the Yocto release schedule (the
time and criteria are documented on the yoctoproject wiki IIRC).

But note, Greg is talking specifically about LTSI, we don't
expect more than one LTSI per year, and we are already locked into
the LTSI 3.4. We've known Greg's strategy and plans for a while, so
this isn't a surprise. He'll do his normal -stable releases for
3.8 and drop them once 3.9 arrives, which is also expected.

Cheers,

Bruce

 However, as far as I understand it the 3.4 snapshot in
git.yoctoproject.org is from kernel.org and not from
http://git.linuxfoundation.org/ltsi-kernel.git. GregKH has been merging
patches into the LTSI kernel, such as AF_BUS, that have not been accepted
by upstream. I do not think that those patches are being merged into the YP
kernel tree. But please correct me if I am wrong.

Cheers,
Rudi

The 3.4 LTSI patches are all present on the 3.4 kernel tree, directly
from Greg's patch queue.

http://git.yoctoproject.org/cgit/cgit.cgi/linux-yocto-3.4/log/?h=ltsi

And that branch is merged into each and every other branch in the
linux-yocto tree.

We've been involved with Greg and LTSI for quite a while now, and are
tracking it via our tree as we discussed with the interested parties.

Cheers,

Bruce
