I use kernel.org docs to read about kernel functions. Now I am trying to make possible reading manuals for kernel-mode functions, such as
man 9 printk. The section 9 is used for this purpose: from
man man section descriptions:
9 - Kernel routines [Non standard]
make mandocs at
/usr/src/linux/ throws this:
make: *** No rule to make target 'mandocs'. Stop.
mandocs is obsolete or was removed). I cannot find man9 packages on my Gentoo GNU/Linux system. Also, I tried to install those manpages on Debian 11 virtual machine, but it fails too.
How can I install/make/download those non-standard manpages for kernel functions to be able to run
man printk to get docs without having to search documentation online or browsing header files?
