Preempt-RT

[ChrisChang1234]

1. I'm looking for the patches that 'Only' enables the "Preemt-RT" feature.

    refer to 

    https://community.nxp.com/t5/NXP-Designs-Knowledge-Base/Enable-Linux-RT-PREEMPT-on-i-MX8M-Products/t...

But I don't know how get the patches for kernel 5.10.72 and 6.1.1x.

2.  Per customer's request, we have to replace the original rootfs with other version.

    If we do so, will the "Preempt RT" feature keep available?

    (in other words, the preempt rt patches impact kernel image only or also including the roots?)

Got it, thanks

1)the owner doesn't update to the latest bsp version, maybe customer needs to change the new bsp source code according to the patches based on 4.1478

2) refer to the readme, these patches are for kernel, customer just needs to change the kernel image, they just replace the new kernel image only
