+ * the ACPI v5.0+ specification. The table consists of a list of
+ * registers which may be memory mapped or hardware registers and also may
+ * include some static integer values.
+ *
+ * CPU performance is on an abstract continuous scale as against a discretized
+ * P-state scale which is tied to CPU frequency only. In brief, the basic
+ * operation involves:
+ *
+ * - OS makes a CPU performance request. (Can provide min and max bounds)
+ *
+ * - Platform (such as BMC) is free to optimize request within requested bounds
+ * depending on power/thermal budgets etc.
+ *
+ * - Platform conveys its decision back to OS
+ *
+ * The communication between OS and platform occurs through another medium
+ * called (PCC) Platform Communication Channel. This is a generic mailbox like
+ * mechanism which includes doorbell semantics to indicate register updates.
+ * See drivers/mailbox/pcc.c for details on PCC.
+ *
+ * Finer details about the PCC and CPPC spec are available in the ACPI v5.1 and
+ * above specifications.

- Broadcom 43xx PCMCIA device support.
-
- Support for 16bit PCMCIA devices.
- Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
- devices, but 32bit CardBUS devices. CardBUS devices are supported
- out of the box by b43.
-
- With this config option you can drive b43 cards in
- CompactFlash formfactor in a PCMCIA adaptor.
- CF b43 cards can sometimes be found in handheld PCs.
-
- It's safe to select Y here, even if you don't have a B43 PCMCIA device.
-
- If unsure, say N.

+ depends on MAC80211 && USB
+ ---help---
+ This is an alternative driver for various Realtek RTL8XXX
+ parts written to utilize the Linux mac80211 stack.
+ The driver is known to work with a number of RTL8723AU,
+ RL8188CU, RTL8188RU, RTL8191CU, and RTL8192CU devices
+
+ This driver is under development and has a limited feature
+ set. In particular it does not yet support 40MHz channels
+ and power management. However it should have a smaller
+ memory footprint than the vendor drivers and benetifs
+ from the in kernel mac80211 stack.
+
+ It can coexist with drivers from drivers/staging/rtl8723au,
+ drivers/staging/rtl8192u, and drivers/net/wireless/rtlwifi,
+ but you will need to control which module you wish to load.
+
+ To compile this driver as a module, choose M here: the module will
+ be called r8xxxu. If unsure, say N.
+
+config RTL8XXXU_UNTESTED
+ bool "Include support for untested Realtek 8xxx USB devices (EXPERIMENTAL)"
+ depends on RTL8XXXU
+ ---help---
+ This option enables detection of Realtek 8723/8188/8191/8192 WiFi
+ USB devices which have not been tested directly by the driver
+ author or reported to be working by third parties.
+
+ Please report your results!

+ * @maxdata_list: If the maximum data value is channel-specific, this points
+ * to an array of maximum data values indexed by channel index.
+ * (Initialized by the low-level driver.)
+ * @range_table: If non-NULL, this points to a COMEDI range table for the

+ * handler during post-configuration.)
+ * @do_cmd: If the subdevice supports asynchronous acquisition commands, this
+ * points to a handler to set it up in hardware. (Initialized by the
+ * low-level driver.)
+ * @do_cmdtest: If the subdevice supports asynchronous acquisition commands,
+ * this points to a handler used to check and possibly tweak a prospective
+ * acquisition command without setting it up in hardware. (Initialized by
+ * the low-level driver.)
+ * @poll: If the subdevice supports asynchronous acquisition commands, this
+ * is an optional pointer to a handler for the %COMEDI_POLL ioctl which
+ * instructs the low-level driver to synchronize buffers. (Initialized by
+ * the low-level driver if needed.)
+ * @cancel: If the subdevice supports asynchronous acquisition commands, this
+ * points to a handler used to terminate a running command. (Initialized
+ * by the low-level driver.)
+ * @buf_change: If the subdevice supports asynchronous acquisition commands,
+ * this is an optional pointer to a handler that is called when the data
+ * buffer for handling asynchronous commands is allocated or reallocated.
+ * (Initialized by the low-level driver if needed.)
+ * @munge: If the subdevice supports asynchronous acquisition commands and
+ * uses DMA to transfer data from the hardware to the acquisition buffer,
+ * this points to a function used to "munge" the data values from the
+ * hardware into the format expected by COMEDI. (Initialized by the
+ * low-level driver if needed.)
+ * @async_dma_dir: If the subdevice supports asynchronous acquisition commands
+ * and uses DMA to transfer data from the hardware to the acquisition
+ * buffer, this sets the DMA direction for the buffer. (initialized to

+ * driver if necessary.)
+ * @state: Handy bit-mask indicating the output states for a DIO or digital
+ * output subdevice with no more than 32 channels. (Initialized by the

+ * @class_dev: If the subdevice supports asynchronous acquisition commands,
+ * this points to a sysfs comediX_subdY device where X is the minor device
+ * number of the COMEDI device and Y is the subdevice number. The minor
+ * device number for the sysfs device is allocated dynamically in the
+ * range 48 to 255. This is used to allow the COMEDI device to be opened
+ * with a different default read or write subdevice. (Allocated during
+ * post-configuration if needed.)
+ * @minor: If @class_dev is set, this is its dynamically allocated minor
+ * device number. (Set during post-configuration if necessary.)
+ * @readback: Optional pointer to memory allocated by
+ * comedi_alloc_subdev_readback() used to hold the values written to
+ * analog output channels so they can be read back. The storage is
+ * automatically freed after the low-level driver's "detach" handler is
+ * called for the device. (Initialized by the low-level driver.)
+ *
+ * This is the main control structure for a COMEDI subdevice. If the subdevice
+ * supports asynchronous acquisition commands, additional information is stored
+ * in the &struct comedi_async pointed to by @async.
+ *
+ * Most of the subdevice is initialized by the low-level driver's "attach" or
+ * "auto_attach" handlers but parts of it are initialized by
+ * comedi_alloc_subdevices(), and other parts are initialized during
+ * post-configuration on return from that handler.
+ *
+ * A low-level driver that sets @insn_bits for a digital input, digital output,

-Driver: cb_pcidas
-Description: MeasurementComputing PCI-DAS series
- with the AMCC S5933 PCI controller
-Author: Ivan Martinez <imr@oersted.dtu.dk>,
- Frank Mori Hess <fmhess@users.sourceforge.net>
-Updated: 2003-3-11
-Devices: [Measurement Computing] PCI-DAS1602/16 (cb_pcidas),
- PCI-DAS1602/16jr, PCI-DAS1602/12, PCI-DAS1200, PCI-DAS1200jr,
- PCI-DAS1000, PCI-DAS1001, PCI_DAS1002
-
-Status:
- There are many reports of the driver being used with most of the
- supported cards. Despite no detailed log is maintained, it can
- be said that the driver is quite tested and stable.
-
- The boards may be autocalibrated using the comedi_calibrate
- utility.
-
-Configuration options: not applicable, uses PCI auto config
-
-For commands, the scanned channels must be consecutive
-(i.e. 4-5-6-7, 2-3-4,...), and must all have the same
-range and aref.
-
-AI Triggering:
- For start_src == TRIG_EXT, the A/D EXTERNAL TRIGGER IN (pin 45) is used.
- For 1602 series, the start_arg is interpreted as follows:
- start_arg == 0 => gated trigger (level high)
- start_arg == CR_INVERT => gated trigger (level low)
- start_arg == CR_EDGE => Rising edge
- start_arg == CR_EDGE | CR_INVERT => Falling edge
- For the other boards the trigger will be done on rising edge

- * There exists a potential lock inversion deadlock scenario when using
- * Lustre on top of ZFS. This occurs between one of ZFS's
- * buf_hash_table.ht_lock's, and Lustre's lu_sites_guard lock. Essentially,
- * thread A will take the lu_sites_guard lock and sleep on the ht_lock,
- * while thread B will take the ht_lock and sleep on the lu_sites_guard
- * lock. Obviously neither thread will wake and drop their respective hold
- * on their lock.
+ * lu_cache_shrink_count returns the number of cached objects that are
+ * candidates to be freed by shrink_slab(). A counter, which tracks
+ * the number of items in the site's lru, is maintained in the per cpu
+ * stats of each site. The counter is incremented when an object is added
+ * to a site's lru and decremented when one is removed. The number of
+ * free-able objects is the sum of all per cpu counters for all sites.
*
- * To prevent this from happening we must ensure the lu_sites_guard lock is
- * not taken while down this code path. ZFS reliably does not set the
- * __GFP_FS bit in its code paths, so this can be used to determine if it
- * is safe to take the lu_sites_guard lock.
- *
- * Ideally we should accurately return the remaining number of cached
- * objects without taking the lu_sites_guard lock, but this is not
- * possible in the current implementation.
+ * Using a per cpu counter is a compromise solution to concurrent access:
+ * lu_object_put() can update the counter without locking the site and
+ * lu_cache_shrink_count can sum the counters without locking each
+ * ls_obj_hash bucket.

-Overview
-
-This document describes the driver set for Unisys Secure Partitioning (s-Par®).
+This document describes the driver set for Unisys Secure Partitioning
+(s-Par(R)).
s-Par is firmware that provides hardware partitioning capabilities for
splitting large-scale Intel x86 servers into multiple isolated
partitions. s-Par provides a set of para-virtualized device drivers to
allow guest partitions on the same server to share devices that would
-normally be unsharable; specifically, PCI network interfaces and host
-bus adapters that do not support shared access via SR-IOV. The shared
-device is owned and managed by a small, single-purpose service
-partition, which communicates with each guest partition sharing that
-device through an area of shared memory called a channel. Additional
-drivers provide support interfaces for communicating with s-Par
-services, logging and diagnostics, and accessing the Linux console
-from the s-Par user interface.
-
-The driver stack consists of a set of support modules, a set of bus
-modules, and a set of device driver modules. The support modules
-handle a number of common functions across each of the other
-drivers. The bus modules provide organization for the device driver
-modules, which provide the shared device functionality.
-
-These drivers are for the Unisys virtual PCI hardware model where the
-hypervisor need not intervene (other than normal interrupt handling)
-in the interactions between the client drivers and the virtual adapter
-firmware in the adapter service partition.
-
-Driver Descriptions
-
-Device Modules
-
-The modules in this section handle shared devices and the virtual
-buses required to support them. These modules use functions in and
-depend on the modules described in the support modules section.
-
-visorchipset
-
-The visorchipset module receives device creation and destruction
-events from the Command service partition of s-Par, as well as
-controlling registration of shared device drivers with the s-Par
-driver core. The events received are used to populate other s-Par
-modules with their assigned shared devices. Visorchipset is required
-for shared device drivers to function properly. Visorchipset also
-stores information for handling dump disk device creation during
-kdump.
-
-In operation, the visorchipset module processes device creation and
-destruction messages sent by s-Par's Command service partition through
-a channel. These messages result in creation (or destruction) of each
-virtual bus and virtual device. Each bus and device is also associated
-with a communication channel, which is used to communicate with one or
-more IO service partitions to perform device IO on behalf of the
-guest.
-
-virthba
-
-The virthba module provides access to a shared SCSI host bus adapter
-and one or more disk devices, by proxying SCSI commands between the
-guest and the service partition that owns the shared SCSI adapter,
-using a channel between the guest and the service partition. The disks
-that appear on the shared bus are defined by the s-Par configuration
-and enforced by the service partition, while the guest driver handles
-sending commands and handling responses. Each disk is shared as a
-whole to a guest. Sharing the bus adapter in this way provides
-resiliency; should the device encounter an error, only the service
+normally be unsharable, specifically:
+
+* visornic - network interface
+* visorhba - scsi disk adapter
+* visorinput - keyboard and mouse
+
+These drivers conform to the standard Linux bus/device model described
+within Documentation/driver-model/, and utilize a driver named visorbus to
+present the virtual busses involved. Drivers in the 'visor*' driver set are
+commonly referred to as "guest drivers" or "client drivers". All drivers
+except visorbus expose a device of a specific usable class to the Linux guest
+environment (e.g., block, network, or input), and are collectively referred
+to as "function drivers".
+
+The back-end for each device is owned and managed by a small,
+single-purpose service partition in the s-Par firmware, which communicates
+with each guest partition sharing that device through an area of shared memory
+called a "channel". In s-Par nomenclature, the back-end is often referred to
+as the "service partition", "IO partition" (for virtual network and scsi disk
+devices), or "console partition" (for virtual keyboard and mouse devices).
+
+Each virtual device requires exactly 1 dedicated channel, which the guest
+driver and back-end use to communicate. The hypervisor need not intervene
+(other than normal interrupt handling) in the interactions that occur across
+this channel.
+
+NOT covered in this document:
+
+* s-Par also supports sharing physical PCI adapters via SR-IOV, but
+ because this requires no specific support in the guest partitions, it will
+ not be discussed in this document. Shared SR-IOV devices should be used
+ wherever possible for highest performance.
+
+* Because the s-Par back-end provides a standard EFI framebuffer to each
+ guest, the already-existing efifb Linux driver is used to provide guest
+ video access. Thus, the only s-Par-unique support that is necessary to
+ provide a guest graphics console are for keyboard and mouse (via visorinput).
+
+
+2. Driver Descriptions
+----------------------
+
+2.1. visorbus
+-------------
+
+2.1.1. Overview
+---------------
+
+The visorbus driver handles the virtual busses on which all of the virtual
+devices reside. It provides a registration function named
+visorbus_register_visor_driver() that is called by each of the function
+drivers at initialization time, which the function driver uses to tell
+visorbus about the device classes (via specifying a list of device type
+GUIDs) it wants to handle. For use by function drivers, visorbus provides
+implementation for struct visor_driver and struct visor_device, as well
+as utility functions for communicating with the back-end.
+
+visorbus is associated with ACPI id "PNP0A07" in modules.alias, so if built
+as a module it will typically be loaded automatically via standard udev or
+systemd (God help us) configurations.
+
+visorbus can similarly force auto-loading of function drivers for virtual
+devices it discovers, as it includes a MODALIAS environment variable of this
+form in the hotplug uevent environment when each virtual device is
+discovered:
+
+ visorbus:<device type GUID>
+
+visorbus notifies each function driver when a device of its registered class
+arrives and departs, by calling the function driver's probe() and remove()
+methods.
+
+The actual struct device objects that correspond to each virtual bus and
+each virtual device are created and owned by visorbus. These device objects
+are created in response to messages from the s-Par back-end received on a
+special control channel called the "controlvm channel" (each guest partition
+has access to exactly 1 controlvm channel), and have a lifetime that is
+independent of the function drivers that control them.
+
+2.1.2. "struct visor device" Function Driver Interfaces
+-------------------------------------------------------
+
+The interface between visorbus and its function drivers is defined in
+visorbus.h, and described below.
+
+When a visor function driver loads, it calls visorbus_register_visor_driver()
+to register itself with visorbus. The significant information passed in this
+exchange is as follows:
+
+* the GUID(s) of the channel type(s) that are handled by this driver, as
+ well as a "friendly name" identifying each (this will be published under
+ /sys/devices/visorbus<x>/dev<y>)
+
+* the addresses of callback functions to be called whenever a virtual
+ device/channel with the appropriate channel-type GUID(s) appears or
+ disappears
+
+* the address of a "channel_interrupt" function, which will be automatically
+ called at specific intervals to enable the driver to poll the device
+ channel for activity
+
+The following functions implemented within each function driver will be
+called automatically by the visorbus driver at appropriate times:
+
+* The probe() function notifies about the creation of each new virtual
+ device/channel instance.
+
+* The remove() function notifies about the destruction of a virtual
+ device/channel instance.
+
+* The channel_interrupt() function is called at frequent intervals to
+ give the function driver an opportunity to poll the virtual device channel
+ for requests. Information is passed to this function to enable the
+ function driver to use the visorchannel_signalinsert() and
+ visorchannel_signalremove() functions to respond to and initiate activity
+ over the channel. (Note that since it is the visorbus driver that
+ determines when this is called, it is very easy to switch to
+ interrupt-driven mechanisms when available for particular virtual device
+ types.)
+
+* The pause() function is called should it ever be necessary to direct the
+ function driver to temporarily stop accessing the device channel. An
+ example of when this is needed is when the service partition implementing
+ the back-end of the virtual device needs to be recovered. After a
+ successful return of pause(), the function driver must not access the
+ device channel until a subsequent resume() occurs.
+
+* The resume() function is the "book-end" to pause(), and is described above.
+
+If/when a function driver creates a Linux device (that needs to be accessed
+from usermode), it calls visorbus_registerdevnode(), passing the major and
+minor number of the device. (Of course not all function drivers will need
+to do this.) This simply creates the appropriate "devmajorminor" sysfs entry
+described below, so that a hotplug script can use it to create a device node.
+
+2.1.3. sysfs Advertised Information
+-----------------------------------
+
+Because visorbus is a standard Linux bus driver in the model described in
+Documentation/driver-model/, the hierarchy of s-Par virtual devices is
+published in the sysfs tree beneath /bus/visorbus/, e.g.,
+/sys/bus/visorbus/devices/ might look like:
+
+ vbus1:dev1 -> ../../../devices/visorbus1/vbus1:dev1
+ vbus1:dev2 -> ../../../devices/visorbus1/vbus1:dev2
+ vbus1:dev3 -> ../../../devices/visorbus1/vbus1:dev3
+ vbus2:dev0 -> ../../../devices/visorbus2/vbus2:dev0
+ vbus2:dev1 -> ../../../devices/visorbus2/vbus2:dev1
+ vbus2:dev2 -> ../../../devices/visorbus2/vbus2:dev2
+ visorbus1 -> ../../../devices/visorbus1
+ visorbus2 -> ../../../devices/visorbus2
+
+visor_device notes:
+
+* Each visorbus<n> entry denotes the existence of a struct visor_device
+ denoting virtual bus #<n>. A unique s-Par channel exists for each such
+ virtual bus.
+
+* Virtual bus numbers uniquely identify s-Par back-end service partitions.
+ In this example, bus 1 corresponds to the s-Par console partition
+ (controls keyboard, video, and mouse), whereas bus 2 corresponds to the
+ s-Par IO partition (controls network and disk).
+
+* Each vbus<x>:dev<y> entry denotes the existence of a struct visor_device
+ denoting virtual device #<y> outboard of virtual bus #<x>. A unique s-Par
+ channel exists for each such virtual device.
+
+* If a function driver has loaded and claimed a particular device, the
+ bus/visorbus/devices/vbus<x>:dev<y>/driver symlink will indicate that
+ function driver.
+
+Every active visorbus device will have a sysfs subtree under:
+
+ /sys/devices/visorbus<x>/vbus<x>:dev<y>/
+
+The following files exist under /sys/devices/visorbus<x>/vbus<x>:dev<y>:
+
+ subsystem link to sysfs tree that describes the
+ visorbus bus type; e.g.:
+ ../../../bus/visorbus
+
+ driver link to sysfs tree that describes the
+ function driver controlling this device;
+ e.g.:
+ ../../../bus/visorbus/drivers/visorhba
+ Note that this "driver" link will not exist
+ if the appropriate function driver has not
+ been loaded yet.
+
+ devmajorminor
+
+ <devname> if applicable, each file here identifies (via
+ ... its file contents) the
+ "<major>:<minor>" needed for a device node to
+ enable access from usermode. There is exactly
+ one file here for each different device node
+ that can be accessed (from usermode). Note
+ that this info is provided by a particular
+ function driver, so these will not exist
+ until AFTER the appropriate function driver
+ controlling this device class is loaded.
+
+ channel properties of the device channel (all in
+ ascii text format)
+
+ clientpartition handle identifying the guest (client) side
+ of this channel, e.g. 0x10000000.
+
+ nbytes total size of this channel in bytes
+
+ physaddr the guest physical address for the base of
+ the channel
+
+ typeguid a GUID identifying the channel type, in
+ xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx notation
+
+ typename a "friendly name" for this channel type, e.g.,
+ "keyboard". Note that this name is provided by
+ a particular function driver, so "typename"
+ will return an empty string until AFTER the
+ appropriate function driver controlling this
+ channel type is loaded
+
+ zoneguid a GUID identifying the channel zone, in
+ xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx notation
+
+
+2.2. visorhba
+-------------
+
+The visorhba driver registers with visorbus as the function driver to
+handle virtual scsi disk devices, specified using the
+SPAR_VHBA_CHANNEL_PROTOCOL_UUID type in the visorbus_register_visor_driver()
+call. visorhba uses scsi_add_host() to expose a Linux block device
+(e.g., /sys/block/) in the guest environment for each s-Par virtual device.
+
+visorhba provides access to a shared SCSI host bus adapter and one or more
+disk devices, by proxying SCSI commands between the guest and the service
+partition that owns the shared SCSI adapter, using a channel between the
+guest and the service partition. The disks that appear on the shared bus
+are defined by the s-Par configuration and enforced by the service partition,
+while the guest driver handles sending commands and handling responses. Each
+disk is shared as a whole to a guest. Sharing the bus adapter in this way
+provides resiliency; should the device encounter an error, only the service
partition is rebooted, and the device is reinitialized. This allows
guests to continue running and to recover from the error.

- * As a result, events might not get handled right away; the actual delay
- * could be anywhere up to twice the requested delay. This doesn't
- * matter, because none of the events are especially time-critical. The
