[meta-freescale] yocto 2.5 sumo linux-qoriq_4.14 question

[Beaman, Thomas]

I currently use yocto2.3 with the meta-freescale layer set to the pyro branch and the linux-qoriq_4.1.bb recipe. This build has the ability to enable PREMPT_RT_BASE in the kernel config.

I am in the process of updating to yocto2.5 with the meta-freescale layer set to the sumo branch and using the linux-qoriq_4.14.bb recipe. This build does not have the ability to enable PREEMPT_RT_BASE.

Do I have something configured incorrectly, or has this been removed or forgotten in the newer yocto2.5 release ?

What other information can I provide.

Regards,
Tom Beaman

Hello Tom,

Maybe a silly question, does PREEMPT_RT_BASE still exit in kernel 4.14?

Regards,
Fernando
