Typically there'll be a firmware method that provides a mask of the controlled devices. Do you have the ACPI tables for a device that implements this? Registering an rfkill interface that claims to only control wifi but which also kills other devices is likely to confuse userspace - it would probably be better to avoid registering the rfkill interface at all in that case. -- Matthew Garrett | mj...@srcf.ucam.org -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
