Hi,
Is there a way to load a kernel module from another module and pass parameters to it? Something like
request_module("mymod param1=val1");
I think this is exactly what you are looking for: from include/linux/kmod.h #define request_module(mod...) __request_module(true, mod) and from kernel/kmod.c /** * __request_module - try to load a kernel module * @wait: wait (or not) for the operation to complete * @fmt: printf style format string for the name of the module * @...: arguments as specified in the format string * * Load a module using the user mode module loader. The function returns * zero on success or a negative errno code or positive exit code from * "modprobe" on failure. Note that a successful module load does not mean * the module did not then unload and exit on an error of its own. Callers * must check that the service they requested is now available not blindly * invoke it. * * If module auto-loading support is disabled then this function * becomes a no-operation. */ int __request_module(bool wait, const char *fmt, ...) In normal situtations, you just call exported functions from another kernel module. Module order and dependencies between these modules are handled by depmod at module installation time, as far as I know.
Thanks, Okash
