But we already have the in-kernel solution that provides this behavior. It is called rfkill-input and it is the in-kernel bridge between input devices that emit KEY_WLAN etc. and rfkill switches. There is no need to have yet another mechanism (most likely fighting with default in-kernel one) doing the same thing. So for boxes tat do support this launcher mode we should simply enable it. _Always_. And once the userspace manager[s] become standard we can just rely on their presence. Like right now you can't really live without udev, dbus, etc. if you want to have reasonably behaving box (embedded setups out of scope here). > >> > > >> > But .. maybe if someone want this default "raw" behavior, > >> > he should just not load this module. > >> > > >> > >> Fully understood, now. > >> > >> Like you siad, we need define a policy for: > >> > >> Â- If user want the default "raw" behavior, what do they need to do? > >> Â Â Â I thought if the wmi driver doesn't load by default, then user > >> Â Â Â Âwill get a "raw" behavior. > >> > > But... > > The wmi driver doesn't just provide the RF switch function, it's also > > have other functions like transfer wmi event to key code. > > > > User doesn't load wmi driver will have "raw" RF switch behavior, but > > lost other more functions. > > > >> Â- If any distro want provide userland solution, how can they disable > >> Â Âthe default "raw" behavior? > >> Â Â Â If anybody want to disable the "raw" behavior, just load the wmi > >> Â Â Â Âdriver. > > Maybe we still add kernel module parameter? > > > > Indeed, I think it would be a good idea to let the user do that. > And I do not think so for the reasons outlined. We have chosen the direction already (dictated by the existence of keys not directly connected withg RF switches) and we should follow through with it, so all boxes and drivers behave as uniformly as possible.
