Re: [RFC][PATCH] Generic Hotkey driver interface

[Alex Williamson <alex.williamson-VXdhtT5mjnY@public.gmane.org>]

Luming,

   Have you considered trying to implement this as a userspace daemon on
top of dev_acpi?  I believe I'm exporting all the of the ACPI interfaces
you'd need to do this.  The acpivideo tool (available along w/ the
latest dev_acpi) does something similar in setting up a notify handler
on the graphics device, and receiving hotkey events.  The hooks are
already there to allow userspace to generate an ACPI event as well.  I'd
be interested in any feedback you have on dev_acpi should you
investigate this approach.  Thanks,

	Alex
