2008-11-16acpi: fix oops in acpi_system_wakeup_device_seq_showLinus Torvalds
Commit 0794469da3f7b2093575cbdfc1108308dd3641ce: ("ACPI: struct device - replace bus_id with dev_name(), dev_set_name()") introduced a bug by testing 'dev_name(ldev)' instead of 'ldev->bus' for NULL when printing out the bus information. So if ldev->bus was NULL, we'd oops.

2008-11-06ACPI: struct device - replace bus_id with dev_name(), dev_set_name()Kay Sievers
This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.

2008-10-03ACPI: Make /proc/acpi/wakeup interface handle PCI devices (again)Rafael J. Wysocki
Make the ACPI /proc/acpi/wakeup interface set the appropriate wake-up bits of physical devices corresponding to the ACPI devices and make those bits be set initially for devices that are enabled to wake up by default. This is needed to restore the 2.6.26 and earlier behavior for the PCI devices that were previously handled correctly with the help of the /proc/acpi/wakeup interface. Signed-off-by: Rafael J.

2008-07-04rtc: fix CMOS time error after writing /proc/acpi/alarmHuacai Chen
When writing /proc/acpi/alarm in adjust mode, e.g. echo "+0000-00-00 00:00:15" >/proc/acpi/alarm The "century" field should be read and added to "year" field before writing, otherwise the CMOS time will go back to 2000 years ago, e.g. # cat /proc/acpi/alarm 0008-06-21 11:38:46 Then the system time may be reset to the date of manufacture after rebooting.

2007-12-27ACPI: /proc/acpi/alarm parsing: handle large numbers properlyYi Yang
In function acpi_system_write_alarm in file drivers/acpi/sleep/proc.c, big sec, min, hr, mo, day and yr are counted twice to get reasonable values, that is very superfluous, we can do that only once. In additon, /proc/acpi/alarm can set a related value which can be specified as YYYY years MM months DD days HH hours MM minutes SS senconds, it isn't a date, so you can specify as +0000-00-00 96:00:00 , that means 3 days later, current code can't handle such a case. This patch removes unnecessary code and does with the aforementioned situation. Before applying this patch: [root@localhost /]# cat /proc/acpi/alarm 2007-12-00 00:00:00 [root@localhost /]# echo "0000-00-00 96:180:180" > /proc/acpi/alarm [root@localhost /]# cat /proc/acpi/alarm 0007-12-02 **:**:** [root@localhost /]# After applying this patch: [root@localhost ~]# echo "2007-12-00 00:00:00" > /proc/acpi/alarm [root@localhost ~]# cat /proc/acpi/alarm 2007-12-00 00:00:00 [root@localhost ~]# echo "0000-00-00 96:180:180" > /proc/acpi/alarm [root@localhost ~]# cat /proc/acpi/alarm 0007-12-04 03:03:00 [root@localhost ~]# Signed-off-by: Yi Yang <yi.y.yang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2007-10-25Fix /proc/acpi/alarm BCD alarm encodingsLinus Torvalds
This fixes some totally illogical and wrong code that converts things to and from BCD mode essentially randomly, does math on values in BCD mode etc etc. Introduce a few helper functions to make it a bit more obvious what is going on, and make sure that we always do all the arithmetic (and anythign else, for that matter) in binary, not BCD.

2007-07-29Introduce CONFIG_SUSPEND for suspend-to-Ram and standbyRafael J. Wysocki
Introduce CONFIG_SUSPEND representing the ability to enter system sleep states, such as the ACPI S3 state, and allow the user to choose SUSPEND and HIBERNATION independently of each other. Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has been chosen and the kernel is intended for SMP systems. Also, introduce CONFIG_PM_SLEEP which is automatically selected if CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the code needed for both suspend and hibernation. The top-level power management headers and the ACPI code related to suspend and hibernation are modified to use the new definitions (the changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce the number of ifdefs). There are many other files in which CONFIG_PM can be replaced with CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in the future. Signed-off-by: Rafael J.

/proc/acpi/sleep has had its own "default n" option, ACPI_SLEEP_PROC_SLEEP, for many months. Time to delete ACPI_SLEEP_PROC_SLEEP. Users that still need /proc/acpi/sleep can still get it along with the other deprecated /proc/acpi files by enabling CONFIG_ACPI_PROCFS. Also delete ACPI_SLEEP_PROC_FS, which was an umbrella for /proc/acpi/sleep, wakeup, alarm, because it was effectively just a synonym for ACPI_SLEEP. Signed-off-by: Len Brown <len.brown@intel.com>

[ With Johannes Berg <johannes@sipsolutions.net> ] Separate the hibernation (aka suspend to disk code) from the other suspend code. In particular: * Remove the definitions related to hibernation from include/linux/pm.h * Introduce struct hibernation_ops and a new hibernate() function to hibernate the system, defined in include/linux/suspend.h * Separate suspend code in kernel/power/main.c from hibernation-related code in kernel/power/disk.c and kernel/power/user.c (with the help of hibernation_ops) * Switch ACPI (the only user of pm_ops.pm_disk_mode) to hibernation_ops Signed-off-by: Rafael J.

2007-04-25ACPI: make /proc/acpi/wakeup more usefulDavid Brownell
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.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
