Reading a configuration file from a driver code during intialization.

[sivakumar.subramani at wipro.com]

Hi all,



For our driver we have following requirement. We have a configuration
file that will be updated by the user and while loading the driver, the
initialization code should read the configuration file to get the value
and use it in the driver code.



Is there is any way to read a configuration file from driver code?



Currently I have written a small kernel module that will create a sysctl
variable and update with a default value. After loading this module,
using shell scripts, I read the configuration file and get the user set
values and update the sysctl variable in that value. Then I will load my
driver where I read the sysctl variable to get the required values set
by the user in the configuration file.



Is there is any other solution to the above problem?



Actually I am looking for some thing similar to Module loadable
parameters in the Linux Device Driver.



Thanks,

~Siva
