Re: Saving kernel module parameters settings

[Nuno Santos <nsantos@xxxxxxxxxx>]

Hi Dimitry,

Thanks for your reply.

Just to contextualize. I ended up implementing the communication between 
userspace and kernel space with binary attributes. I have only needed to 
implement two of them.

One of those binary attributes is responsible for getting the state to 
be shown on controlpanel and setting the state back to the device based 
on control panel changes.

Basicly, what I need is to have a copy of that binary attribute saved in 
order to load it into module internal state variable when module loads.

Do you think is possible to achieve this goal?

Thanks,

With my best regards,

Nuno
