As I said, I don't think there's any harm in causing it - I think I was getting more promising results from hotkey events in the Z when I called ECON, but I don't have access to that machine right now and never got it finished off. > > The numbers correspond to enabling all events.

Looking through, the implementation seems quite different but the functionality seems the same - the newer machines seem to return values directly, whereas older ones tended to trap into SMM. The wireless control (at least, the enumeration call I make) seems to be a noop on these older machines. It /looks/ like we can probably get some sort of versioning information about the interface by calling SN00. I think that would probably be a better approach than using DMI for this. I've put this into rawhide, so I suspect we'll hear complaints if it breaks things for anybody. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
