ACPI AC/Battery/SBS driver has different kernel option for procfs and sysfs I/F. This patch, 1. Change CONFIG_ACPI_PROCFS_POWER to 'n' by default so that we can remove it in the next release or two. 2. Remove CONFIG_ACPI_SYSFS_POWER and always build in the sysfs I/F of these drivers.

This patch provides the same information through debugfs, which previously was provided through /proc/acpi/embedded_controller/*/info This is the gpe the EC is connected to and whether the global lock gets used. The io ports used are added to /proc/ioports in another patch. Beside the fact that /proc/acpi is deprecated for quite some time, this info is not needed for applications and thus can be moved to debugfs instead of a public interface like /sys.

Hardware Error Device (PNP0C33) is used to report some hardware errors notified via SCI, mainly the corrected errors. Some APEI Generic Hardware Error Source (GHES) may use SCI on hardware error device to notify hardware error to kernel. After receiving notification from ACPI core, it is forwarded to all listeners via a notifier chain. The listener such as APEI GHES should check corresponding error source for new events when notified.

APEI stands for ACPI Platform Error Interface, which allows to report errors (for example from the chipset) to the operating system. This improves NMI handling especially. In addition it supports error serialization and error injection. For more information about APEI, please refer to ACPI Specification version 4.0, chapter 17. This patch provides some common functions used by more than one APEI tables, mainly framework of interpreter for EINJ and ERST. A machine readable language is defined for EINJ and ERST for OS to execute, and so to drive the firmware to fulfill the corresponding functions. The machine language for EINJ and ERST is compatible, so a common framework is defined for them.

This driver exposes ACPI 4.0 compliant power meters as hardware monitoring devices. This second revision of the driver also exports the ACPI string info as sysfs attributes, a list of the devices that the meter measures, and will send ACPI notifications over the ACPI netlink socket. This latest revision only enables the power capping controls if it can be confirmed that the power cap can be enforced by the hardware and explains how the notification interfaces work.

ACPI 4.0 created the logical "processor aggregator device" as a mechinism for platforms to ask the OS to force otherwise busy processors to enter (power saving) idle. The intent is to lower power consumption to ride-out transient electrical and thermal emergencies, rather than powering off the server. On platforms that can save more power/performance via P-states, the platform will first exhaust P-states before forcing idle. However, the relative benefit of P-states vs. idle states is platform dependent, and thus this driver need not know or care about it. This driver does not use the kernel's CPU hot-plug mechanism because after the transient emergency is over, the system must be returned to its normal state, and hotplug would permanently break both cpusets and binding. So to force idle, the driver creates a power saving thread. The scheduler will migrate the thread to the preferred CPU. The thread has max priority and has SCHED_RR policy, so it can occupy one CPU. To save power, the thread will invoke the deep C-state entry instructions. To avoid starvation, the thread will sleep 5% of the time time for every second (current RT scheduler has threshold to avoid starvation, but if other CPUs are idle, the CPU can borrow CPU timer from other, which makes the mechanism not work here) Vaidyanathan Srinivasan has proposed scheduler enhancements to allow injecting idle time into the system. This driver doesn't depend on those enhancements, but could cut over to them when they are available. Peter Z. does not favor upstreaming this driver until the those scheduler enhancements are in place. However, we favor upstreaming this driver now because it is useful now, and can be enhanced over time.

Initially CONFIG_PM_SLEEP was defined as CONFIG_SUSPEND || CONFIG_HIBERNATION and some ACPI code, most importantly the code in drivers/acpi/main.c, was written with this assumption. Currently, however, CONFIG_PM_SLEEP is also set when CONFIG_XEN_SAVE_RESTORE is set. This causes some compilation warnings to appear in drivers/acpi/main.c if both CONFIG_SUSPEND and CONFIG_HIBERNATION are unset and CONFIG_PM_SLEEP is set (this was impossible before). To fix this problem, redefine CONFIG_ACPI_SLEEP do depend directly on CONFIG_SUSPEND || CONFIG_HIBERNATION, as originally intended, and use it instead of CONFIG_PM_SLEEP in drivers/acpi/main.c, wherever appropriate. Additionally, move the acpi_target_sleep_state definition from under the #ifdef to prevent compilation from failing in some cases. Signed-off-by: NRafael J.

This essentially reverts commit 71fc47a9 ("ACPI: basic initramfs DSDT override support"), because the code simply isn't ready. It did ugly things to the init sequence to populate the rootfs image early, but that just ended up showing other problems with the whole approach. The fact is, the VFS layer simply isn't initialized this early, and the relevant ACPI code should either run much later, or this shouldn't be done at all. For 2.6.25, we'll just pick the latter option. We can revisit this concept later if necessary.
