I suspect that for a lot of cases, exporting this to userspace would be helpful - it's often easier for us to do this mapping in hal and just push out an updated fdi file than it would be to push out an updated kernel driver. > Userspace - the WMI mapper disregards the WMI-ACPI spec on this point, and > does _not_ try to export to userspace, since WMI does not exist on Linux. > All callers of the WMI mapper are assumed to be kernel space drivers. And for similar reasons, I think it would be helpful to provide userspace with the ability to trigger WMI calls. It's going to be easier for people to add GUIDs to a userspace file than to extend a kernel driver, even if there are some cases that are better handled by having a full in-kernel driver. -- 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
