I've a question regarding the building of the linux kernel, more specifically
which kernel to build.
I've previously built the kernel for an 86 arch but this time I want to build
for the RaspberryPi. I can easily get the current version of the installed
kernel with the "uname -a" command but that doesn't tell me the git repo
where the kernel originated. I'd imagine that it's from the RPi git repo, but
that adds another level of confusion as that git repo doesn't have any tags at
all. So even given the version number from uname how to check out a suitable
version of the kernel.
Did you read the https://www.raspberrypi.org/documentation/linux/kernel/building.md ?
There is a few tags : https://github.com/raspberrypi/linux/releases
I could take the latest from the RPi repo and use "make oldconfig" but I
wonder how far, in kernel versions, I can jump and not affect the installed
libs and utilities which have been built against another version of the
kernel?
The problem is not the user space programs, it's really if the newer kernel will boot in your hardware.
If you use the RPi kernel, you can use the lasted kernel without problems, but if you use the mainline kernel (Linus) you will have a few problems.
Just because it doesn't have all the modifications made on RPi kernel.
I've read various documentation on building the linux kernel but that's never
really mentioned, mainly I guess as you're building for the x86 Arch. But even
there can you jump major versions of kernel without effecting other installed
SW in the system?
If you read this docs you are able to test different kernel versions without problems. So go test it.
