Re: PREEMPT_RT patches


Yocto has supported a PREEMPT_RT kernel as long as I can remember.

There are recipes for linux-yocto-rt for the kernel itself, and a core-image-rt image recipe right in poky.

It's also pretty straightforward to use a different kernel recipe, such as one from a vendor, and apply the PREEMPT_RT patches in a .bbappend, provided the recipe version lines up with the patches.

Recently I heard somewhere that newer versions of the Linux Kernel will include the PREEMPT_RT patches, and configuration settings would be used to set how the Linux would operate in a specific system.


Does Yocto support “PREEMPT_RT”, and what versions of Yocto have this option ?


Is there documentation on this feature/option ?
