ACPI battery interface reports its state either in mW or in mA, and discharge rate in your case is reported in mW. power_supply interface does not have such a parameter, so current_now parameter is used for all cases. But in case of mW, reported discharge should be converted into mA.

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.

Tejun's commit 7b595756 made sysfs attribute->owner unnecessary. But the field was left in the structure to ease the merge. It's been over a year since that change and it is now time to start killing attribute->owner along with its users - one arch at a time! This patch is attempt #1 to get rid of attribute->owner only for CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on as and when possible - avr32 will be the next since that is something I can test. Compile (make allyesconfig / make allmodconfig / custom config) and boot tested. akpm: the idea is that we put the declaration of sttribute.owner inside `#ifndef CONFIG_X86'. But that proved to be too ambitious for now because new usages kept on turning up in subsystem trees.

Acer BIOS has a bug which is exposed when a dead battery is present. The package template that is used to describe battery status is over-written with sane values when the battery is live. But when the batter is dead, a bogus reference in the template is used. In this case, Linux returns a fault, when instead it should simply return that it doesn't know the missing value. http://bugzilla.kernel.org/show_bug.cgi?id=8573 http://bugzilla.kernel.org/show_bug.cgi?id=10202Signed-off-by: NAlexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: NLen Brown <len.brown@intel.com>

If a battery is at a critical charge level and not being charged or discharged, then the ACPI _BST method will return a state of 4, and the current acpi_battery_get_property() code will not set any property value for POWER_SUPPLY_PROP_STATUS. This will cause an oops in power_supply_show_property() when it reads off the end of the status_text array. This actually was causing a 100% reproducible crash on boot on my laptop with two batteries, when one battery was completely drained and the laptop was not plugged in. Fix this by making sure acpi_battery_get_property() returns POWER_SUPPLY_STATUS_UNKNOWN for any battery state it doesn't already handle explicitly. There doesn't seem to be any status enum value defined that makes more sense than 'unknown' for a battery at a critical charge level.

The previous events patch added a netlink event for every user of the legacy /proc/acpi/event interface. However, some users of /proc/acpi/event are really input events, and they already report their events via the input layer. Introduce a new interface, acpi_bus_generate_netlink_event(), which is explicitly called by devices that want to repoprt events via netlink. This allows the input-like events to opt-out of generating netlink events. In summary: events that are sent via netlink: ac/battery/sbs thermal processor thinkpad_acpi dock/bay events that are sent via input layer: button video hotkey thinkpad_acpi hotkey asus_acpi/asus-laptop hotkey sonypi/sonylaptop Signed-off-by: NZhang Rui <rui.zhang@intel.com> Signed-off-by: NLen Brown <len.brown@intel.com>

/proc exports _BST in a single file, and _BST is re-evaulated whenever that file is read. Sometimes user-space reads this file frequently, and on some systems _BST takes a long time to evaluate due to a slow EC. Further, when we move to sysfs, the values returned from _BST will be in multiple files, and evaluating _BST for each file read would make matters worse. Here code is added to support caching the results of _BST. A new module parameter "update_time" tells how many seconds the cached _BST should be used before it is re-evaluated. Currently, update_time defaults to 0, and so the existing behaviour of re-evaluating on each read retained.
