Hi, I was looking at code that is used to parse the kernel comand line. I found the __setup() macro, and that it uses the obs_kernel_param struct. What i understand is that if i need to pass an additional argument say foo, like foo=...
then i do:
int bar(char *str)
{
...
...
}__setup("foo=", bar);Now, in init/main.c, the kernel calls parse_args(...). This however calls parse_one(...) in kernel/params.c. It handles all the params and then if it does not get a match calls unknown_bootoption() which calls obs_checksetup() which handles the __setup() cases.
My question is this: what is the difference between these two "conventions"? And how can i "register" using the new format?
TIA rahul
