[shravankumaralugala]

I am build yocto for iMX8MP board I would like to add rt-linux patch to kernel but I found rt-patches are

not matching with the availble kernel with in imx repo. 

Kindly suggest which version of iMX kernel is matching with the availble rt patches.

Thanks for the prompt help.

Do you have rt support rt patch for latest kernel = >5.15. Right now no rt linux available for latest kernel >= 5.15 correct me if I am wrong, Are you going to release any RT linux/ RT patch for latest kernel in future.

Hi Dhruvit Vasavada,
Thanks for your response. From the Link you provide I understand that "community decided to merge the PREEMPT_RT kernel changes into mainline." Can you please provide tentative release date.
