[PATCH 0/5] meta-rt: create a real-time (PREEMPT_RT) layer

[PATCH 0/5] meta-rt: create a real-time (PREEMPT_RT) layer

[Darren Hart]

Add a real-time layer to build the linux-yocto preempt_rt kernel type for
specific machines. It also adds the rt-tests test suite. This series
adds qemux86-64 support as well as atom-pc. Both have been boot tested.

There has been much discussion surrounding where real-time support should be
in the repositories. Most recently we discussed including it as part of the
main poky repository. I think this makes the most sense as the rt kernels are
built from the same kernel repositories as the other linux-yocto kernels.

[PATCH 1/5] meta-rt: Initial PREEMPT_RT layer and kernel recipes

[Darren Hart]

The meta-rt layer provides a preempt_rt kernel recipe
using the linux-yocto-stable git tree. It overrides
the virtual/kernel provider and defines the compatible
machines and per-machine SRCREVs. The initial layer
supports only qemux86-64.

This reminds me of the discussion we were having about the emenlow
BSPs, and that we never resolved.

I suggested that we need some interim overrides options for these
variables so I can update a master set of SRCREVs and have the
BSPs updated, and a flag/variable that would allow a BSP to also
opt-out of getting a more global SRCREV assigned.

If we don't do solve this, none of these BSPs will pickup CVEs/bug
fixes or global config changes .. and we'll have a problem.

Comments ?

And as we discussed, I'll help clean this up when I get the recipe
refactoring done. I'm just trying to decide if I can get away with
including a .bb file instead of creation more .inc files :)
