Question Enhanced Real Time Clock Support - Missing Kernel Option


In regards to compiling a custom kernel:

When using make menuconfig - under Device Drivers --> Character Devices --> there should be an option with the label "Enhanced Real Time Clock Support" (CONFIG_JS_RTC).

The problem is that this option seems to only show up while using the menu method when other options are either enabled or disabled and I've entirely forgotten what should be what. I swear fingered it out once.

This is on an older computer (P4) so HPET is no good.
You would think that disabling the HPET option would enable the RTC option but that does not appear to be the case.

If anyone happens to know the magic sequence or has some ideas on where to start I would greatly appreciate some help.

I understand I can just add the option to the .config file and avoid this hassle but I'm very interested to know how to make this work.

To show my appreciation I will do something nice for you such as call you a nice name or tell you that you are pretty (or ugly if that's what you prefer).

Also, feel free to tell me if this is a stupid request or that I don't know what I'm talking about (because I don't).

cd to your linux source dir, and try:
Code:
find -name Kconfig | xargs -i grep -H rtc {} | less

Cheers,
Tink
