I'm trying to make dCore-xenial kernel into rt kernel. I read a post on forum on how to do it for tiny core. http://forum.tinycorelinux.net/index.php?topic=9082.0
"download patched kernel source and its config from
download latest rt (PREEMT RT) patch for tc kernel (it is currently 220.127.116.11) from kernel.org
cd to linux
apply rt patch
cp kernel config to .config
make menuconfig (if you want to make changes)
If I understand right you need the kernel version of the patch that match the kernel version of dCore-xenial. I look for the patch on the kernel.org site but there is only version of 4.1 and 4.4. But dCore-xenial is 4.2.9. Now I don't know which one to use or how to patch it. Is there some trick to do or need to use the old kernel version 3.18. (dCore-willy or later).
I'm wondering if you can give me some info on how to do it, or direct me to some site. I will appreciate any advice or idea.
