Hello Hank Wang,

There are a couple of ways to do this. You could create an append recipe (.bbappend) to your recipes to add the changes. You can find more regarding this on the Yocto Project Reference Manual:

https://www.yoctoproject.org/docs/latest/ref-manual/ref-manual.html#ref-classes-patch

If you already have a patch file you can use the do_patch function of bitbake. There is also information on the Yocto Projecr Manual.

I hope this helps!

Regards,
