Smile Why are there so many different versions of linux kernels?


Hello all together,

this is my first post and I am still a noob in the linux world. The change that, I bought my self a beagleboneblack. I wanted for learning purposes to create my own minimal linux with buildroot.

I use this repo: https://github.com/fhunleth/buildroot-bbb

There my question comes up: For buildroot buidling the kernel, I have to tell buildroot, where it can get the kernel from. I noticed, that there are special repos for the beagleboneblack-kernel. I thought, that in all systems, the kernel would be the same (of course in different versions). But what is for example special about the beagleboneblack that it needs its own kernel?

I hope this question is not to obvious to solve, but I could not find a real answer in the internet.

Thank you for your responses.
Best regards

Normally it is because the kit has custom patches that have not yet been merged with the generic kernel.

I'm not sure, but this could be because some ARM v8 things have not been merged - ARM v9 has been, I believe (could be wrong - it depends on how old some may be.

Also, there could be some special drivers for the board that don't yet exist in the mainline kernel.

Most ARM CPUs are for microcontrollers... But are now sufficiently complete to include MMU and paging capability.

So things change. The most recent generic kernels might have them.
