echo "C093" > /proc/acpi/wakeup but i think "c093" should also be ok. i.e. "echo 'c093' > /proc/acpi/wakeup" should have the same result as "echo 'C093' > /proc/acpi/wakeup".

Not at all, i didn't find any userland application assumes /proc/acpi/wakeup must be that kind of format. In fact, /proc output is always changing. :-) > > Maybe this file should be left for compatibility and we should present > something reasonable in /sys?

PCI ID can be gotten from sysfs, but it is a unique identifier for a device, a user can get device name from /usr/share/hwdata/pci.ids in any dstribution by PCI ID, he/she is unnecessary to use bus number to get device name, bus number is platform-specific, but PCI ID is platform-independent. > Pavel > > > [EMAIL PROTECTED] ~]# cat /proc/acpi/wakeup > > Device S-state Status Sysfs node > > C093 S5 disabled pci:0000:00:1e.0 > > C0E8 S3 disabled pci:0000:00:1d.0 > > C0EF S3 disabled pci:0000:00:1d.1 > > C0F0 S3 disabled pci:0000:00:1d.2 > > C0F1 S3 disabled pci:0000:00:1d.3 > > C0F2 S3 disabled pci:0000:00:1d.7 > > C0F9 S0 disabled pci:0000:00:1c.0 > > C21D S0 disabled pci:0000:08:00.0 > > C109 S5 disabled pci:0000:00:1c.1 > > C228 S5 disabled pci:0000:10:00.0 > > C10F S5 disabled pci:0000:00:1c.3 > > C229 S5 disabled > > [EMAIL PROTECTED] ~]# > > > > After applying this patch, the output is: > > > > [EMAIL PROTECTED] ~]# cat /proc/acpi/wakeup > > Device S-state Status Sysfs node PCI ID > > C093 S5 disabled pci:0000:00:1e.0 0x2448 > > C0E8 S3 disabled pci:0000:00:1d.0 0x27c8 > > C0EF S3 disabled pci:0000:00:1d.1 0x27c9 > > C0F0 S3 disabled pci:0000:00:1d.2 0x27ca > > C0F1 S3 disabled pci:0000:00:1d.3 0x27cb > > C0F2 S3 disabled pci:0000:00:1d.7 0x27cc > > C0F9 S0 disabled pci:0000:00:1c.0 0x27d0 > > C21D S0 disabled pci:0000:08:00.0 0x16fd > > C109 S5 disabled pci:0000:00:1c.1 0x27d2 > > C228 S5 disabled pci:0000:10:00.0 0x4222 > > C10F S5 disabled pci:0000:00:1c.3 0x27d6 > > C229 S5 disabled > - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
