Actually. jessie on the pi wasn't too bad. I am actually getting things done with it. But info on the wintel stuff is common knowledge. Want to replace the armhf (pi) or arm64 (rock64) kernel with a realtime version? Nobody else sees the need, so your questions get ignored, not answered by the people who do have it all figured out. Thats BS.
For the pi, shouldn't it just be a matter of following your distro's build-your- own-kernel instructions, using the pi-specific kernel sources and base config, and applying the rt patchset on top?
No clue, I built it for the rock64, on the rock64, useing the patches from the linux-rt mailing list links, but when I asked how to install it, 3 times over about as many weeks, and got ignored, I gave up. Their propaganda says good support, but AFAIWC, there isn't any. But the pi is only very marginally better. Bulding an rt kernel on the pi is a several hour project, on the rock64 its about 30 minutes, which amply demo's the difference in speeds. Too bad I cannot use it. Neither has any docs available to aid the hacker. Those are proprietary designs. Run the linux they supply, or go pound sand.
Or does the patchset not apply cleanly or something? (Assuming you're building directly on the pi. If not, start with cross-compiler or qemu arm emulation setup, also per your distro. I went the qemu route.)

Take care now, E. Liddell.
