Subject: make /proc/acpi/wakeup more useful
From: David Brownell <[EMAIL PROTECTED]>
This updates /proc/acpi/wakeup to be more informative, primarily by showing
the sysfs node associated with each wakeup-enabled device. Example:
Device S-state Status Sysfs node
PCI0 S4 disabled no-bus:pci0000:00
PS2M S4 disabled pnp:00:05
PS2K S4 disabled pnp:00:06
UAR1 S4 disabled pnp:00:08
USB1 S3 disabled pci:0000:00:03.0
USB2 S3 disabled pci:0000:00:03.1
USB3 S3 disabled
USB4 S3 disabled pci:0000:00:03.3
S139 S4 disabled
LAN S4 disabled pci:0000:00:04.0
MDM S4 disabled
AUD S4 disabled pci:0000:00:02.7
SLPB S4 *enabled
Eventually this file should be removed, but until then it's almost the only
way we have to tell how the relevant ACPI tables are broken (and cope). In
that example, two devices don't actually exist (USB3, S139), one can't issue
wakeup events (PCI0), and two seem harmlessly (?) confused (MDM and AUD are
the same PCI device, but it's the _modem_ that does wake-on-ring).
In particular, we need to be sure driver model nodes are properly hooked
up before we can get rid of this ACPI-only interface for wakeup events.
