2015-10-12ACPI: Introduce CPU performance controls using CPPCAshwin Chaugule
CPPC stands for Collaborative Processor Performance Controls and is defined in the ACPI v5.0+ spec. It describes CPU performance controls on an abstract and continuous scale allowing the platform (e.g. remote power processor) to flexibly optimize CPU performance with its knowledge of power budgets and other architecture specific knowledge. This patch adds a shim which exports commonly used functions to get and set CPPC specific controls for each CPU. This enables CPUFreq drivers to gather per CPU performance data and use with exisiting governors or even allows for customized governors which are implemented inside CPUFreq drivers.

2015-08-25ACPI: Decouple ACPI idle and ACPI processor driversAshwin Chaugule
This patch introduces a new Kconfig symbol, ACPI_PROCESSOR_IDLE, which is auto selected by architectures which support the ACPI based C states for CPU Idle management. The processor_idle driver in its present form contains declarations specific to X86 and IA64. Since there are no reasonable defaults for other architectures e.g. ARM64, the driver is selected only for X86 or IA64. This helps in decoupling the ACPI processor_driver from the ACPI processor_idle driver which is useful for the upcoming alternative patchwork for controlling CPU Performance (CPPC) and CPU Idle (LPI).

2015-08-25ACPI: Split out ACPI PSS from ACPI Processor driverAshwin Chaugule
The ACPI processor driver is currently tied too closely to the ACPI P-states (PSS) and other related constructs for controlling CPU performance. The newer ACPI specification (v5.1 onwards) introduces alternative methods to PSS. These new mechanisms are described within each ACPI Processor object and so they need to be scanned whenever a new Processor object is detected. This patch introduces a new Kconfig symbol to allow for finer configurability among the two options for controlling performance states. There is no change in functionality and the option is auto-selected by the architectures which support it. A future commit will introduce support for CPPC: A newer method of controlling CPU performance. The OS is not expected to support CPPC and PSS at the same time, so the Kconfig option lets us make the two mutually exclusive at compile time.

git://git.kernel.org/pub/scm/linux/kernel/git/djbw/nvdimm Pull libnvdimm subsystem from Dan Williams: "The libnvdimm sub-system introduces, in addition to the libnvdimm-core, 4 drivers / enabling modules: NFIT: Instantiates an "nvdimm bus" with the core and registers memory devices (NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware Interface table). After registering NVDIMMs the NFIT driver then registers "region" devices. A libnvdimm-region defines an access mode and the boundaries of persistent memory media. A region may span multiple NVDIMMs that are interleaved by the hardware memory controller. In turn, a libnvdimm-region can be carved into a "namespace" device and bound to the PMEM or BLK driver which will attach a Linux block device (disk) interface to the memory. PMEM: Initially merged in v4.1 this driver for contiguous spans of persistent memory address ranges is re-worked to drive PMEM-namespaces emitted by the libnvdimm-core. In this update the PMEM driver, on x86, gains the ability to assert that writes to persistent memory have been flushed all the way through the caches and buffers in the platform to persistent media. See memcpy_to_pmem() and wmb_pmem(). BLK: This new driver enables access to persistent memory media through "Block Data Windows" as defined by the NFIT. The primary difference of this driver to PMEM is that only a small window of persistent memory is mapped into system address space at any given point in time. Per-NVDIMM windows are reprogrammed at run time, per-I/O, to access different portions of the media. BLK-mode, by definition, does not support DAX. BTT: This is a library, optionally consumed by either PMEM or BLK, that converts a byte-accessible namespace into a disk with atomic sector update semantics (prevents sector tearing on crash or power loss). The sinister aspect of sector tearing is that most applications do not know they have a atomic sector dependency. At least today's disk's rarely ever tear sectors and if they do one almost certainly gets a CRC error on access. NVDIMMs will always tear and always silently. Until an application is audited to be robust in the presence of sector-tearing the usage of BTT is recommended.

2015-06-19acpi-video-detect: video: Make video_detect code part of the video moduleHans de Goede
This is a preparation patch for the backlight interface selection logic cleanup, there are 2 reasons to not always build the video_detect code into the kernel: 1) In order for the video_detect.c to also deal with / select native backlight interfaces on win8 systems, instead of doing this in video.c where it does not belong, video_detect.c needs to call into the backlight class code. Which cannot be done if it is builtin and the blacklight class is not. 2) Currently all the platform/x86 drivers which have quirks to prefer the vendor driver over acpi-video call acpi_video_unregister_backlight() to remove the acpi-video backlight interface, this logic really belongs in video_detect.c, which will cause video_detect.c to depend on symbols of video.c and video.c already depends on video_detect.c symbols, so they really need to be a single module. Note that this commits make 2 changes so as to maintain 100% kernel commandline compatibility: 1) The __setup call for the acpi_backlight= handling is moved to acpi/util.c as __setup may only be used by code which is alwasy builtin 2) video.c is renamed to acpi_video.c so that it can be combined with video_detect.c into video.ko This commit also makes changes to drivers/platform/x86/Kconfig to ensure that drivers which use acpi_video_backlight_support() from video_detect.c, will not be built-in when acpi_video is not built in. This also changes some "select" uses to "depends on" to avoid dependency loops.

2015-03-26ACPI: move arm64 GSI IRQ model to generic GSI IRQ layerLorenzo Pieralisi
The code deployed to implement GSI linux IRQ numbers mapping on arm64 turns out to be generic enough so that it can be moved to ACPI core code along with its respective config option ACPI_GENERIC_GSI selectable on architectures that can reuse the same code. Current ACPI IRQ mapping code is not integrated in the kernel IRQ domain infrastructure, in particular there is no way to look-up the IRQ domain associated with a particular interrupt controller, so this first version of GSI generic code carries out the GSI<->IRQ mapping relying on the IRQ default domain which is supposed to be always set on a specific architecture in case the domain structure passed to irq_create/find_mapping() functions is missing. This patch moves the arm64 acpi functions that implement the gsi mappings: acpi_gsi_to_irq() acpi_register_gsi() acpi_unregister_gsi() to ACPI core code. Since the generic GSI<->domain mapping is based on IRQ domains, it can be extended as soon as a way to map an interrupt controller to an IRQ domain is implemented for ACPI in the IRQ domain layer. x86 and ia64 code for GSI mappings cannot rely on the generic GSI layer at present for legacy reasons, so they do not select the ACPI_GENERIC_GSI config options and keep relying on their arch specific GSI mapping layer.

2014-11-04ACPI: Add support for device specific propertiesMika Westerberg
Device Tree is used in many embedded systems to describe the system configuration to the OS. It supports attaching properties or name-value pairs to the devices it describe. With these properties one can pass additional information to the drivers that would not be available otherwise. ACPI is another configuration mechanism (among other things) typically seen, but not limited to, x86 machines. ACPI allows passing arbitrary data from methods but there has not been mechanism equivalent to Device Tree until the introduction of _DSD in the recent publication of the ACPI 5.1 specification. In order to facilitate ACPI usage in systems where Device Tree is typically used, it would be beneficial to standardize a way to retrieve Device Tree style properties from ACPI devices, which is what we do in this patch. If a given device described in ACPI namespace wants to export properties it must implement _DSD method (Device Specific Data, introduced with ACPI 5.1) that returns the properties in a package of packages. For example: Name (_DSD, Package () { ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () {"name1", <VALUE1>}, Package () {"name2", <VALUE2>}, ... } }) The UUID reserved for properties is daffd814-6eba-4d8c-8a91-bc9bbf4aa301 and is documented in the ACPI 5.1 companion document called "_DSD Implementation Guide" [1], [2]. We add several helper functions that can be used to extract these properties and convert them to different Linux data types. The ultimate goal is that we only have one device property API that retrieves the requested properties from Device Tree or from ACPI transparent to the caller.

2014-05-30ACPI / PNP: use device ID list for PNPACPI device enumerationZhang Rui
ACPI can be used to enumerate PNP devices, but the code does not handle this in the right way currently. Namely, if an ACPI device object 1. Has a _CRS method, 2. Has an identification of "three capital characters followed by four hex digits", 3. Is not in the excluded IDs list, it will be enumerated to PNP bus (that is, a PNP device object will be create for it). This means that, actually, the PNP bus type is used as the default bus type for enumerating _HID devices in ACPI. However, more and more _HID devices need to be enumerated to the platform bus instead (that is, platform device objects need to be created for them). As a result, the device ID list in acpi_platform.c is used to enforce creating platform device objects rather than PNP device objects for matching devices. That list has been continuously growing recently, unfortunately, and it is pretty much guaranteed to grow even more in the future. To address that problem it is better to enumerate _HID devices as platform devices by default. To this end, change the way of enumerating PNP devices by adding a PNP ACPI scan handler that will use a device ID list to create PNP devices for the ACPI device objects whose device IDs are present in that list. The initial device ID list in the PNP ACPI scan handler contains all of the pnp_device_id strings from all the existing PNP drivers, so this change should be transparent to the PNP core and all of the PNP drivers. Still, in the future it should be possible to reduce its size by converting PNP drivers that need not be PNP for any technical reasons into platform drivers.

2013-06-27ACPI: Add CMOS RTC Operation Region handler supportLan Tianyu
On HP Folio 13-2000, the BIOS defines a CMOS RTC Operation Region and the EC's _REG methord accesses that region. Thus an appropriate address space handler must be registered for that region before the EC driver is loaded. Introduce a mechanism for adding CMOS RTC address space handlers. Register an ACPI scan handler for CMOS RTC devices such that, when a device of that kind is detected during an ACPI namespace scan, a common CMOS RTC operation region address space handler will be installed for it.

2013-05-22ACPI / PM: Allow device power states to be used for CONFIG_PM unsetRafael J. Wysocki
Currently, drivers/acpi/device_pm.c depends on CONFIG_PM and all of the functions defined in there are replaced with static inline stubs if that option is unset. However, CONFIG_PM means, roughly, "runtime PM or suspend/hibernation support" and some of those functions are useful regardless of that. For example, they are used by the ACPI fan driver for controlling fans and acpi_device_set_power() is called during device removal. Moreover, device initialization may depend on setting device power states properly. For these reasons, make the routines manipulating ACPI device power states defined in drivers/acpi/device_pm.c available for CONFIG_PM unset too.

2013-05-12ACPI / processor: Use common hotplug infrastructureRafael J. Wysocki
Split the ACPI processor driver into two parts, one that is non-modular, resides in the ACPI core and handles the enumeration and hotplug of processors and one that implements the rest of the existing processor driver functionality. The non-modular part uses an ACPI scan handler object to enumerate processors on the basis of information provided by the ACPI namespace and to hook up with the common ACPI hotplug infrastructure. It also populates the ACPI handle of each processor device having a corresponding object in the ACPI namespace, which allows the driver proper to bind to those devices, and makes the driver bind to them if it is readily available (i.e. loaded) when the scan handler's .attach() routine is running. There are a few reasons to make this change. First, switching the ACPI processor driver to using the common ACPI hotplug infrastructure reduces code duplication and size considerably, even though a new file is created along with a header comment etc. Second, since the common hotplug code attempts to offline devices before starting the (non-reversible) removal procedure, it will abort (and possibly roll back) hot-remove operations involving processors if cpu_down() returns an error code for one of them instead of continuing them blindly (if /sys/firmware/acpi/hotplug/force_remove is unset). That is a more desirable behavior than what the current code does. Finally, the separation of the scan/hotplug part from the driver proper makes it possible to simplify the driver's .remove() routine, because it doesn't need to worry about the possible cleanup related to processor removal any more (the scan/hotplug part is responsible for that now) and can handle device removal and driver removal symmetricaly (i.e. as appropriate). Some user-visible changes in sysfs are made (for example, the 'sysdev' link from the ACPI device node to the processor device's directory is gone and a 'physical_node' link is present instead and a corresponding 'firmware_node' is present in the processor device's directory, the processor driver is now visible under /sys/bus/cpu/drivers/ and bound to the processor device), but that shouldn't affect the functionality that users care about (frequency scaling, C-states and thermal management).

2013-03-21ACPI / scan: Add special handler for Intel Lynxpoint LPSS devicesRafael J. Wysocki
Devices on the Intel Lynxpoint Low Power Subsystem (LPSS) have some common features that aren't shared with any other platform devices, including the clock and LTR (Latency Tolerance Reporting) registers. It is better to handle those features in common code than to bother device drivers with doing that (I/O functionality-wise the LPSS devices are generally compatible with other devices that don't have those special registers and may be handled by the same drivers). The clock registers of the LPSS devices are now taken care of by the special clk-x86-lpss driver, but the MMIO mappings used for accessing those registers can also be used for accessing the LTR registers on those devices (LTR support for the Lynxpoint LPSS is going to be added by a subsequent patch). Thus it is convenient to add a special ACPI scan handler for the Lynxpoint LPSS devices that will create the MMIO mappings for accessing the clock (and LTR in the future) registers and will register the LPSS devices' clocks, so the clk-x86-lpss driver will only need to take care of the main Lynxpoint LPSS clock. Introduce a special ACPI scan handler for Intel Lynxpoint LPSS devices as described above. This also reduces overhead related to browsing the ACPI namespace in search of the LPSS devices before the registration of their clocks, removes some LPSS-specific (and somewhat ugly) code from acpi_platform.c and shrinks the overall code size slightly.

2013-01-19ACPI: add support for CSRT tableMika Westerberg
Core System Resources Table (CSRT) is a proprietary ACPI table that contains resources for certain devices that are not found in the DSDT table. Typically a shared DMA controller might be found here. This patch adds support for this table. We go through all entries in the table and make platform devices of them. The resources from the table are passed with the platform device. There is one special resource in the table and it is the DMA request line base and number of request lines. This information might be needed by the DMA controller driver as it needs to map the ACPI DMA request line number to the actual request line understood by the hardware. This range is passed as IORESOURCE_DMA resource.

2012-11-15ACPI: Add support for platform bus typeMika Westerberg
With ACPI 5 it is now possible to enumerate traditional SoC peripherals, like serial bus controllers and slave devices behind them. These devices are typically based on IP-blocks used in many existing SoC platforms and platform drivers for them may already be present in the kernel tree. To make driver "porting" more straightforward, add ACPI support to the platform bus type. Instead of writing ACPI "glue" drivers for the existing platform drivers, register the platform bus type with ACPI to create platform device objects for the drivers and bind the corresponding ACPI handles to those platform devices. This should allow us to reuse the existing platform drivers for the devices in question with the minimum amount of modifications. This changeset is based on Mika Westerberg's and Mathias Nyman's work.

The original resource conflict checking in APEI code will check memory/ioport accessed by APEI via general resource management mechanism. But ACPI NVS region is marked as busy already, so that the false resource conflict will prevent APEI ERST/EINJ to work.
