Hey, I've sent this before, ages ago, but haven't really followed through with it. I still think it would be useful for many scenarios where a plain number is a clumsy interface for a module param.
Thoughts?
We should not be adding new module parameters anyway (they operate on code, not data/devices), so what would this be used for?
I think it's just easier to use names than random values, and this also gives you range check on the input.
I also keep telling people not to add new module parameters, but it's not like they're going away anytime soon.
If there's a solution to being able to pass device specific debug parameters at probe time, I'm all ears. At least i915 has a bunch of things which can't really be changed after probe, when debugfs for the device is around. Module parameters aren't ideal, but debugfs doesn't work for this.
