Man pages for Kernel API
Hi, Like there is section #2 of man pages dedicated to syscalls, is there any official way to get the list of all supported Kernal APIs?

check out the man page for man itself (man man) look for this: 9 Kernel routines [Non standard] You may need to install them (man 9 files) as they may not be installed ###### example john@vega:~/download/koans$ man -k printk printk (9) - print a kernel message printk_timed_ratelimit (9) - caller-controlled printk ratelimiting snd_printd (9) - debug printk snd_printdd (9) - debug printk snd_printk (9) - printk wrapper trace_printk (9) - printf formatting in the ftrace buffer
i dont know which distro you ( Dipanjan Das ) using , but in fedora i should use something like this for kmalloc : ┌─[✗]─[13:18:11]─[navid@HOME] └──> ~ $ >> man -k kmalloc probe::vm.kmalloc (3stap) - Fires when kmalloc is requested probe::vm.kmalloc_node (3stap) - Fires when kmalloc_node is requested ┌─[13:18:12]─[navid@HOME] └──> ~ $ >> man probe::vm.kmalloc seems man files divided to probe and subsystem vm and functions. if you cannot find yet, you should ask your distro IRC/mailing list to what to do next. best wishes, -navid On Tue, Jun 3, 2014 at 10:49 PM, John de la Garza <john@jjdev.com> wrote:

###### example
john@vega:~/download/koans$ man -k printk printk (9) - print a kernel message printk_timed_ratelimit (9) - caller-controlled printk ratelimiting snd_printd (9) - debug printk snd_printdd (9) - debug printk snd_printk (9) - printk wrapper trace_printk (9) - printf formatting in the ftrace buffer

thank you frank , for make this clear . so frank in this case can you be more specific , what should i do ? for example i installed kernel-doc , even downloaded kernel man page from kernel.org and completed make install routine . but , for example i don't have any kmalloc man page yet in my fedora . last time i was in arch linux , i had it . best wishes, -navid On Thu, Jun 5, 2014 at 2:49 AM, Frank Ch.

Those are systemtap man pages, not kernel API ones.

ok . i figure it out . you should have have have kernel source tree ( which i think most of us had). any way if you dont : $git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git $cd linux $make mandocs #make installmandocs #mandb (and yes you should have xmlto and other package installed ) i hope this will help. best wishes, -navid On Thu, Jun 5, 2014 at 4:44 AM, navid Rahimi <rahimi.nv@gmail.com> wrote:
