Re: kernel module

[Luca <lucarx76@xxxxxxxxx>]

You are right. My module has been compiled into the kernel though. 
But when the kernel starts I do not see it registered.

This is what I did
1)saved my module .c file in drivers/crypto/
2)edited drivers/kernel/Makefile adding obj-$(CONFIG_CRYPTO_MYMODULE) += mymodule.o 
3)edited the drivers/crypto/Kconfig adding 
 config CRYPTO_MYMODULE
 tristate "My module test"
 help 
   Enable to test it

4)make menuconfig => setting my module to be built into the kernel

Thank you,
 Luca

 i'm pretty sure that you can only use that "mymodule.param" notation
on the kernel command line for modules that have been *compiled into*
the kernel, no?  that won't work for loadable modules, but i'm willing
to be corrected.
