Unable to build device driver modules in kernel 4.4.6 using genkernel

Normally I configure my kernel by hand, but I am trying out using genkernel with menuconfig for simplicity's sake on a new laptop.

Here's my process:

Code:

# make defconfig

# genkernel --menuconfig all

Once menuconfig comes up, I am unable to select Y for any device drivers, I can only cycle through N and M.

Running

Code:

make menuconfig

on this new .config yeilds the same results as above.

If I

Code:

# make defconfig

# make menuconfig

I can select Y, N and M.

This leads me to think that genkernel is configuring the kernel in a way that prevents this option from being set.

I ran

Code:

# diff -C0

on the two .configs to see if I could see anything that would be causing this. The result was 6000 lines.

Before I spend hours going through this diff, I wanted to ask if anyone knows what could be causing this?

Thanks.

You can not use Y if any parent option is set as M. You could use make localmodconfig instead of make defconfig. See /usr/src/linux/README for other make targets.

Thanks for pointing me towards the readme, never knew that existed. I played around with the various options but in the end every time I used genkernel it still caused the same result (even the parent itmes could not be set to Y). I decided to ditch genkernel because of this.
