Re: kernel 2.6 config for module load

[Jim]

Hello,

I have a device driver which can be configurated in kernel 2.4 to be a 
loadable module. But, in kernel 2.6, I made it as tristate in Kconfig. 
On make menuconfig list, I can only select it to [*]NewModule for kernel 
built-in, I cannot select it to [M]NewModule for loadable module 
(neither did I press key M or Space key produce [M]). Is it wrong to 
specify tristate in Kconfig to make a loadable module in kernel 2.6? Or 
what was I missing in kernel 2.6 config?

Thank you.

Jim

Tristate is OK.  Of course, you will also need
CONFIG_MODULES=y
to enable module support.  Is that enabled?

There are a few hundred examples of tristate loadable modules
in Kconfig files that you could look at.
