Hello All,

Has anyone set up an environment on EL7 (desktop or laptop) where one
can cross-compile a kernel for ARM- specifically, Raspberry Pi?

I am very impressed with how well the EL7 images work- especially with
how the kernel is integrated into the rest of the OS.  However, I want
to have a realtime/low latency kernel.  The shortest path to get there
from here is to download Emlid's Raspbian image, burn it to SD card,
wipe out the root filesystem, and copy the EL7 root filesystem in its
place.

This works, to an extent, but hardware isn't working properly
(keyboard and other USB devices).  What does work is if I just use the
Emlid image as-is.

So, I would like to compile a custom kernel, the same kernel used with
the EL7 images, with the PREEMPT_RT patch applied.  What's the easiest
way to do this?

Thanks!
-JK
