The primary documentation is at: https://wiki.linuxfoundation.org/realtime/preempt_rt_versions Please clone the linux-stable-rt git repo directly and switch to the stable rt version you want, instead of manually applying the RT patch. > Patch the kernel and set up .config file to choose Preemptable kernel (Real-Time). > Then I compile it, it produces linux-upstream files which I did not expect. > Making the kernel looked good and then fails with the following error- > Initially it gives the following warnings- Vendor patches or instructions cannot be supported here. Please clone the repository earlier shown, switch to the stable rt version you need (list of stable rt releases are in the aforementioned link), mention the tag you've used, then show the exact build command sequence you did. Afterwards, hopefully I can provide some further help. Good luck, -- Ahmed S. Darwish Linutronix GmbH
