One could hope this was nicely documented in kernel/irq/Kconfig.
But that file contains only 9 lines of comments for 10 config symbols.

Maybe it is just me but I was struggeling understanding the purpose
of these config symbols.

I found the individual bits of genirq nicely documented in most cases.
But the overall picture was/is hard to get.

And I never got enough understanding to write up something myself :-(
