How to know the Options supported by kernel driver?

s.verma · 10-13-2015, 05:34 AM

Hello all,

I want to know where can I find what options does a kernel driver supports and it's related documentation.
So that I can know what options to put for a driver if necessary in
/etc/modprobe.d/

What option for what kernel driver?

If you need special options probably best to exercise your favourite search engine. Else modinfo will give you the parameters the module accepts.

My question was generic. I have seen lot of sites on which there are instruction for putting option. So I want to know is there some standard documentation available with a hardware driver e.g. ethernet driver like tg3, rtl8192ce driver or i915 graphics driver, which lists all the possible option for a driver. Where I can find that.

I recently checked linux source for Documentation but i.e. very much confusing to me.

Thanks. I found parameter listed.
Does modinfo lists all the parameters or only some currently in use.

All of them - may vary between release levels.
