[linux-yocto] [PATCH] [meta-realtime] Add rt-app and define core-image-realtime

[Insop Song]

Hi Bruce,

This is for adding rt-app, please let me know what you think.
For next patch, I will add schedtool_dl

Regards,

Insop

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

  - run example

  root at qemux86:~# rt-app -t 100000:35000:d -D 1
  [rt-app] <notice> [0] Using SCHED_DEADLINE policy:
