I am considering upgrading the kernel of my Raspberry Pi router to 3.19. But how can I do this?
I have found an out-of-tree nl80211-compatible driver for
rtl8188cus that supports
hostapd and acs, but it calls for a 3.19 kernel. How do I build this 3.19 kernel, maybe libc, and upgrade my Pi to it?
I have a 20-core server running Ubuntu 14.04 and I have to cross compile using that, or the compiling time will not be tolerable. Please give me instructions on how that is to be done.
EDIT: I have not tried to cary this out yet, as I don't have the expertise in debugging such situations (and previous experiences of failed LFS builds left me pretty scarred.) I need some clear instructions on how this should be done, Cross Linux From Scratch style.
