------- Comment #1 from [EMAIL PROTECTED] 2008-01-09 23:03 ------- Created an attachment (id=14392) --> (http://bugzilla.kernel.org/attachment.cgi?id=14392&action=view) Convert procfs to sysfs for /proc/acpi/wakeup /proc/acpi/wakeup is deprecated but it has to exist because we haven't a sysfs interface to replace it yet, this patch converts /proc/acpi/wakeup to sysfs interface, under every acpi device sysfs node, a user can see a directory "wakeup" if the acpi device can support wakeup, there are six files under this directory: acpi_bus_id bus_id pci_id run_wakeup sleep_state status All the files are read-only exclude "status" which is used to enable or disable wakeup of the acpi device. "acpi_bus_id" is acpi bus ID of the acpi device. "bus_id" is pci bus id of the device associated to the acpi device, it will be empty if there isn't any device associated to it. "pci_id" is PCI ID of the pci device associated to the acpi device, it will be empty if there isn't any device associated to it. "run_wake" is a flag indicating if a wakeup process is being handled. "sleep_state" is sleep state of the acpi device such as "S0". "status" is wakeup status of the acpi device, it is enabled or disabled, a user can change it be echoing "0", "1", "disabled" or "enabled" to /sys/devices/.../wakeup/status. Here is the test result: [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 [EMAIL PROTECTED] ~]# find /sys -name "*" | grep sleep_state /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:05/wakeup/sleep_state /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:0d/wakeup/sleep_state /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:11/wakeup/sleep_state /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:15/wakeup/sleep_state /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:19/wakeup/sleep_state /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:1d/wakeup/sleep_state /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2b/wakeup/sleep_state /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2b/device:2c/wakeup/sleep_state /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2d/wakeup/sleep_state /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2d/device:2e/wakeup/sleep_state /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2f/wakeup/sleep_state /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2f/device:30/wakeup/sleep_state [EMAIL PROTECTED] ~]# ls /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2f/device:30/wakeup acpi_bus_id bus_id pci_id run_wakeup sleep_state status [EMAIL PROTECTED] ~]# cat /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2f/device:30/acpi_bus_id cat: /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2f/device:30/acpi_bus_id: No such file or directory [EMAIL PROTECTED] ~]# cat /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2f/device:30/wakeup/acpi_bus_id C229 [EMAIL PROTECTED] ~]# cat /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2f/device:30/wakeup/sleep_state S5 [EMAIL PROTECTED] ~]# cat /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2f/device:30/wakeup/status disabled [EMAIL PROTECTED] ~]# cat /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2f/device:30/wakeup/bus_id [EMAIL PROTECTED] ~]# cat /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2f/device:30/wakeup/pci_id [EMAIL PROTECTED] ~]# echo 1 > /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2f/device:30/wakeup/status [EMAIL PROTECTED] ~]# cat /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2f/device:30/wakeup/status enabled [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 enabled pci:0000:00:1c.0 0x27d0 C21D S0 enabled pci:0000:08:00.0 0x16fd C109 S5 enabled pci:0000:00:1c.1 0x27d2 C228 S5 enabled pci:0000:10:00.0 0x4222 C10F S5 enabled pci:0000:00:1c.3 0x27d6 C229 S5 enabled [EMAIL PROTECTED] ~]# vi /var/log/dmesg [EMAIL PROTECTED] ~]# dmesg | grep "same GPE" ACPI: 'C0F9' and 'C229' have the same GPE, can't disable/enable one seperately ACPI: 'C21D' and 'C229' have the same GPE, can't disable/enable one seperately ACPI: 'C109' and 'C229' have the same GPE, can't disable/enable one seperately ACPI: 'C228' and 'C229' have the same GPE, can't disable/enable one seperately ACPI: 'C10F' and 'C229' have the same GPE, can't disable/enable one seperately [EMAIL PROTECTED] ~]# cat /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/*/wakeup/status disabled disabled disabled disabled disabled disabled enabled enabled enabled [EMAIL PROTECTED] ~]# cat /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/*/*/wakeup/status enabled enabled enabled [EMAIL PROTECTED] ~]# -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
