Receiving ACPI notifications generically

Receiving ACPI notifications generically

[Matthew Garrett]

It seems that Acer laptops send an ACPI notification when bay devices
are hotplugged (Notify (\_SB.PCI0.IDE0.SECN.BAY1, 0x01)). Obviously,
I /could/ catch this by writing a small driver that hooks the
notification and then use that to send an ACPI event. Is there any way
to do this from userspace? Can the generic hotkey driver be subverted in
this way?

Please send me output of acpidmp, then I can show you an example how to configure generic-hotkey-driver for this case. BTW, we need to add battery-hotplug code to respond this event.

I'm afraid I don't have the machine to hand (and so can't send a full
acpidmp), but here's the DSDT:

Huh, is this ide-bay-hotplug?

Try this:

echo "0:\\_SB.PCI0.IDE0.SECN.BAY1::\\_SB.PCI0.IDE0.SECN.BAY1::1:1" > event_config
