How to creat a .config file for a driver and How to use it in a device driver?????
Hi all ...
i am writing a device driver in which the default configuration for LCD display i need to keep it in a .config file so that as the system boots it take the value from this file and does the initial configuration in the init of the driver. If user changes the .config file content in the next boot the LCD driver should take the new default configuration
There will also be a run time config which could be changed at the rum time but will not change the default configuration.
i am writing a LCD driver for PPC arch i need to know that how should i creat a .config file and How should i use it my device driver. ??????
If you had an exprience in this regard please do share with me ...

You don't. The safe way is to have sane defaults in the driver. Then write a user mode app that reads the config file and configures the driver properly, probably through ioctls.

Ya i got your point ...the way you told is the very generic way of doing this but what i need is this :-
Like your any .config if you edit your configuration and restart your default configuration changes ....The merit of this technique is that i need not compile the driver with every default config change ....
