2012-12-14Merge branch 'x86-acpi-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 ACPI update from Peter Anvin: "This is a patchset which didn't make the last merge window. It adds a debugging capability to feed ACPI tables via the initramfs. On a grander scope, it formalizes using the initramfs protocol for feeding arbitrary blobs which need to be accessed early to the kernel: they are fed first in the initramfs blob (lots of bootloaders can concatenate this at boot time, others can use a single file) in an uncompressed cpio archive using filenames starting with "kernel/". The ACPI maintainers requested that this patchset be fed via the x86 tree rather than the ACPI tree as the footprint in the general x86 code is much bigger than in the ACPI code proper." * 'x86-acpi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: X86 ACPI: Use #ifdef not #if for CONFIG_X86 check ACPI: Fix build when disabled ACPI: Document ACPI table overriding via initrd ACPI: Create acpi_table_taint() function to avoid code duplication ACPI: Implement physical address table override ACPI: Store valid ACPI tables passed via early initrd in reserved memblock areas x86, acpi: Introduce x86 arch specific arch_reserve_mem_area() for e820 handling lib: Add early cpio decoder
2012-11-23i2c / ACPI: add ACPI enumeration supportMika Westerberg
ACPI 5 introduced I2cSerialBus resource that makes it possible to enumerate and configure the I2C slave devices behind the I2C controller. This patch adds helper functions to support I2C slave enumeration. An ACPI enabled I2C controller driver only needs to call acpi_i2c_register_devices() in order to get its slave devices enumerated, created and bound to the corresponding ACPI handle.

2012-09-29efi: Fix the ACPI BGRT driver for images located in EFI boot services memoryJosh Triplett
The ACPI BGRT driver accesses the BIOS logo image when it initializes. However, ACPI 5.0 (which introduces the BGRT) recommends putting the logo image in EFI boot services memory, so that the OS can reclaim that memory. Production systems follow this recommendation, breaking the ACPI BGRT driver. Move the bulk of the BGRT code to run during a new EFI late initialization phase, which occurs after switching EFI to virtual mode, and after initializing ACPI, but before freeing boot services memory. Copy the BIOS logo image to kernel memory at that point, and make it accessible to the BGRT driver. Rework the existing ACPI BGRT driver to act as a simple wrapper exposing that image (and the properties from the BGRT) via sysfs.

2011-01-20kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

2011-01-12ACPI: delete CONFIG_ACPI_PROCFS_POWER and power procfs I/F in 2.6.39Zhang Rui
sysfs I/F for ACPI power devices, including AC and Battery, has been working in upstream kenrel since 2.6.24, Sep 2007. In 2.6.37, we made the sysfs I/F always built in and this option disabled by default. Now, we plan to remove this option and the ACPI power procfs interface in 2.6.39. First, update the feature-removal-schedule to announce this change. Second, add runtime warnings in ACPI AC/Battery/SBS driver, so that users will notice this change even if "make oldconfig" is used.

2011-01-12ACPI: update CONFIG_ACPI_PROCFS descriptionZhang Rui
Update CONFIG_ACPI_PROCFS description because the processor, video and thermal zone procfs I/F have been removed. Some ACPI drivers, e.g. button, have their procfs I/F always built in, because we don't have sysfs I/F replacement at the moment. But once we finish developing the sysfs I/F for these driver, we need CONFIG_ACPI_PROCFS to enabled/disable the corresponding procfs I/F. So just updating the description rather than removing this option, although there is no procfs I/F depends on it for now.

2010-12-14IPMI/ACPI: Add the IPMI opregion driver to enable ACPI to access BMC controllerZhao Yakui
ACPI 4.0 spec adds the ACPI IPMI opregion, which means that the ACPI AML code can also communicate with the BMC controller. This is to install the ACPI IPMI opregion and enable the ACPI to access the BMC controller through the IPMI message. It will create IPMI user interface for every IPMI device detected in ACPI namespace and install the corresponding IPMI opregion space handler. Then it can enable ACPI to access the BMC controller through the IPMI message. The following describes how to process the IPMI request in IPMI space handler: 1. format the IPMI message based on the request in AML code. IPMI system address. Now the address type is SYSTEM_INTERFACE_ADDR_TYPE IPMI net function & command IPMI message payload 2. send the IPMI message by using the function of ipmi_request_settime 3. wait for the completion of IPMI message. It can be done in different routes: One is in handled in IPMI user recv callback function. Another is handled in timeout function. 4. format the IPMI response and return it to ACPI AML code. At the same time it also addes the module dependency. The ACPI IPMI opregion will depend on the IPMI subsystem.

Some APEI Generic Hardware Error Source (GHES) may use SCI on hardware error device to notify hardware error to kernel.

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.

2009-07-31ACPI: create Processor Aggregator Device driverShaohua Li
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.

Remove CONFIG_ACPI_POWER. It was always set the same as CONFIG_ACPI, and it had no menu label, so there was no way to set it to anything other than "y". The interfaces under CONFIG_ACPI_POWER (acpi_device_sleep_wake(), acpi_power_transition(), etc) are called unconditionally from the ACPI core, so we already depend on it always being present.
