Bruce,
That's very good. I will bring linux-yocto-3.8 kernel to meta-dl.
(https://github.com/insop/meta-dl/tree/linux-yocto-3.8)
I have another suggestion to offer here, one I've been wanting to
do for a bit.
I've added Darren Hart to the thread, since I'd like to hear from
him on this as well.
I have a use for the scheduling tools and benchmark cases for some
virtualization usecases (meta-virtualization on git.yoctoproject.org).
We already have "recipes-rt" in oe-core, and the preempt-rt kernel
available from linux-yocto, and as we've been discussing I've added
support for EDF/sched_dealine in linux-yocto-3.8.
I'm not a fan of having to many layers, but rather than putting these
efforts in github layers, hiding them in meta-virtualiation and they
aren't yet "core" enough to go in oe-core .. I'd rather see them
conslidated in a "meta-realtime" (or whatever name we decide on)
layer on git.yoctoproject.org.
meta-realtime sounds good to me, and this can include schedulers
real-time application and testing suits.
There are also ideas around interrupt management, AMP, and alternative
system partitioning that I'd like to drive into such a layer.
Good idea to add these continuously to the "meta-realtime"
A quick scan of the layer index, doesn't show anything that matches
this description. So I'm suggesting that we create a new layer
to consolidate these approaches, and a layer that can be consumed by
some of the other layers that are currently in progress.
Comments ? In particular, point out a layer that already does this that
I've missed.
I've took out machine related from my previous meta-dl-qemux86 and put
together meta-realtime as a starting point. It has two sched_deadline
testing program.
It's on github for now for your reference, but I am willing to move or
merge to git.yocto.

Thanks. I'll have a look, I have my own local meta-realtime as well,
so I can consolidate the two and see about getting them hosted on
git.yoctoproject.org.
Cheers,
Bruce
Thank you,
Insop
