option for driver sony-laptop missing [SOLVED]

[dextermagnific]

Hi everybody,

I have just downloaded the latest gentoo-sources-3.2.0 and I cannot find the option to check for the sony-laptop driver.
I can find it by performing a search using the "/" command in "make menuconfig". It says it is located in
device drivers -> X86 platform specific drivers

but when I search it in this menu it is missing. Doing a search in the source tree shows that the source file is present "sony-laptop.c" but no way to make it compile by selecting it in the "make menuconfig" (it is missing).

I tried to add it manually in the generated ".config" file and touch the necessary files so this file does not get regenerated when invoking "make" but the driver is still not compiled.

Any suggestions on how to force this driver to compile and make it build into the kernel ?

Thanks

its visibility depends on CONFIG_INPUT, CONFIG_RFKILL and CONFIG_ACPI being enabled.

Ok thanks, I forgot to activate RKFILL.
