Changing the settings of the device driver

Changing the settings of the device driver

[Nuno Santos]

Hi,

I have been reading about linux kernel development and ioctl seems to be 
discouraged by kernel developers.

However ioctl is precisely what i'm looking for to mimic what I have in 
my Windows driver version.

Should I consider an option to implement ioctl's to change my device 
settings?

Thanks,

Nuno

What kind of settings?
By the way give sysfs a thought.

Because Linux not Windows mimicking one platform's behavior on another
is usually not the best option. We actually discouraging driver- and
vendor-specific interfaces between kernel and userspace and striving
towards drivers (both kernel- and user-space) that are able to handle
multitude of devices from different vendors.

Maybe if you provided more details about your device (what it is
exactly, what the protocol is, what exact issues you are trying to
solve) people could direct you towards some of existing solutions.

Thanks.
