[PATCH 0/1] [meta-realtime] Add rt-app, schedtool, define core-image-realtime, and append recipies-kernel

[Insop Song]

meta-realtime layer for testing sched_deadline and other real-time applications

Add rt-app, schedtool, define core-image-realtime, and append recipies-kernel

*applications tested are shown below:

1. rt-app
- "rt-app" is a test application that starts multiple periodic threads
  in order to simulate a real-time periodic load

This looks good to me now, I still think we'll have some confusion
between the core "rt" images and core-image-realtime that we are
introducing here.

I may rename it core-image-realtime-extended as part of the merge,
if that's acceptable to you ? I think it will be something that
we'll need to revisit at some point, but that's not a good reason
to hold this back anymore.

I'll merge, do a quick test and push this out on Monday.

Cheers,

Bruce

"core-image-realtime-extended" or "core-image-rt-extended (to be
aligned with existing core-image-rt)" or something along this line
sounds fine to me.

I was thinking of updating my patch, but it would be better if you
decide the final name, so I won't update the patch for now.
Or if you know which name is the best, then just let me know, I will
update the patch and send it to you.

Thank you,

Insop

I went with core-image-rt-extended this morning.

The changes have been merged, briefly tested and pushed to the
yocto layer.

I've also created a docs/ subirectory in the layer, if you have
test steps, READMEs or other information to contribute, that's the
place we should put it.

We can tweak this as required from here.

Cheers,

Bruce

Thank you and will update the docs dir soon.
