consistent or non-consistent memory as it sees fit. By using this API,
you are guaranteeing to the platform that you have all the correct and
necessary sync points for this memory in the driver.
+
+DMA_ATTR_NO_KERNEL_MAPPING
+--------------------------
+
+DMA_ATTR_NO_KERNEL_MAPPING lets the platform to avoid creating a kernel
+virtual mapping for the allocated buffer. On some architectures creating
+such mapping is non-trivial task and consumes very limited resources
+(like kernel virtual address space or dma consistent address space).
+Buffers allocated with this attribute can be only passed to user space
+by calling dma_mmap_attrs(). By using this API, you are guaranteeing
+that you won't dereference the pointer returned by dma_alloc_attr(). You
+can threat it as a cookie that must be passed to dma_mmap_attrs() and
+dma_free_attrs(). Make sure that both of these also get this attribute
+set on each call.
+
+Since it is optional for platforms to implement
+DMA_ATTR_NO_KERNEL_MAPPING, those that do not will simply ignore the
+attribute and exhibit default behavior.
+
+DMA_ATTR_SKIP_CPU_SYNC
+----------------------
+
+By default dma_map_{single,page,sg} functions family transfer a given
+buffer from CPU domain to device domain. Some advanced use cases might
+require sharing a buffer between more than one device. This requires
+having a mapping created separately for each device and is usually
+performed by calling dma_map_{single,page,sg} function more than once
+for the given buffer with device pointer to each device taking part in
+the buffer sharing. The first call transfers a buffer from 'CPU' domain
+to 'device' domain, what synchronizes CPU caches for the given region
+(usually it means that the cache has been flushed or invalidated
+depending on the dma direction). However, next calls to
+dma_map_{single,page,sg}() for other devices will perform exactly the
+same sychronization operation on the CPU cache. CPU cache sychronization
+might be a time consuming operation, especially if the buffers are
+large, so it is highly recommended to avoid it if possible.
+DMA_ATTR_SKIP_CPU_SYNC allows platform code to skip synchronization of
+the CPU cache for the given buffer assuming that it has been already
+transferred to 'device' domain. This attribute can be also used for
+dma_unmap_{single,page,sg} functions family to force buffer to stay in
+device domain after releasing a mapping for it. Use this attribute with
+care!

+HugeTLB Controller
+-------------------
+
+The HugeTLB controller allows to limit the HugeTLB usage per control group and
+enforces the controller limit during page fault. Since HugeTLB doesn't
+support page reclaim, enforcing the limit at page fault time implies that,
+the application will get SIGBUS signal if it tries to access HugeTLB pages
+beyond its limit. This requires the application to know beforehand how much
+HugeTLB pages it would require for its use.
+
+HugeTLB controller can be created by first mounting the cgroup filesystem.
+
+# mount -t cgroup -o hugetlb none /sys/fs/cgroup
+
+With the above step, the initial or the parent HugeTLB group becomes
+visible at /sys/fs/cgroup. At bootup, this group includes all the tasks in
+the system. /sys/fs/cgroup/tasks lists the tasks in this cgroup.
+
+New groups can be created under the parent group /sys/fs/cgroup.
+
+# cd /sys/fs/cgroup
+# mkdir g1
+# echo $$ > g1/tasks
+
+The above steps create a new group g1 and move the current shell
+process (bash) into it.

+Specifying PWM information for devices
+======================================
+
+1) PWM user nodes
+-----------------
+
+PWM users should specify a list of PWM devices that they want to use
+with a property containing a 'pwm-list':
+
+ pwm-list ::= <single-pwm> [pwm-list]
+ single-pwm ::= <pwm-phandle> <pwm-specifier>
+ pwm-phandle : phandle to PWM controller node
+ pwm-specifier : array of #pwm-cells specifying the given PWM
+ (controller specific)
+
+PWM properties should be named "pwms". The exact meaning of each pwms
+property must be documented in the device tree binding for each device.
+An optional property "pwm-names" may contain a list of strings to label
+each of the PWM devices listed in the "pwms" property. If no "pwm-names"
+property is given, the name of the user node will be used as fallback.
+
+Drivers for devices that use more than a single PWM device can use the
+"pwm-names" property to map the name of the PWM device requested by the
+pwm_get() call to an index into the list given by the "pwms" property.
+
+The following example could be used to describe a PWM-based backlight
+device:
+
+ pwm: pwm {
+ #pwm-cells = <2>;
+ };
+
+ [...]
+
+ bl: backlight {
+ pwms = <&pwm 0 5000000>;
+ pwm-names = "backlight";
+ };
+
+pwm-specifier typically encodes the chip-relative PWM number and the PWM
+period in nanoseconds. Note that in the example above, specifying the
+"pwm-names" is redundant because the name "backlight" would be used as
+fallback anyway.
+
+2) PWM controller nodes
+-----------------------
+
+PWM controller nodes must specify the number of cells used for the
+specifier using the '#pwm-cells' property.
+
+An example PWM controller might look like this:
+
+ pwm: pwm@7000a000 {
+ compatible = "nvidia,tegra20-pwm";
+ reg = <0x7000a000 0x100>;
+ #pwm-cells = <2>;
+ };
--- /dev/null
+* Universal Asynchronous Receiver/Transmitter (UART)
+
+- compatible: "cavium,octeon-3860-uart"
+
+ Compatibility with all cn3XXX, cn5XXX and cn6XXX SOCs.
+
+- reg: The base address of the UART register bank.
+
+- interrupts: A single interrupt specifier.
+
+- current-speed: Optional, the current bit rate in bits per second.
+
+Example:
+ uart1: serial@1180000000c00 {
+ compatible = "cavium,octeon-3860-uart","ns16550";
+ reg = <0x11800 0x00000c00 0x0 0x400>;
+ current-speed = <115200>;
+ interrupts = <0 35>;
+ };
--- /dev/null
+pwm-backlight bindings
+
+Required properties:
+ - compatible: "pwm-backlight"
+ - pwms: OF device-tree PWM specification (see PWM binding[0])
+ - brightness-levels: Array of distinct brightness levels. Typically these
+ are in the range from 0 to 255, but any range starting at 0 will do.
+ The actual brightness level (PWM duty cycle) will be interpolated
+ from these values. 0 means a 0% duty cycle (darkest/off), while the
+ last value in the array represents a 100% duty cycle (brightest).
+ - default-brightness-level: the default brightness level (index into the
+ array defined by the "brightness-levels" property)
+
+Optional properties:
+ - pwm-names: a list of names for the PWM devices specified in the
+ "pwms" property (see PWM binding[0])
+
+[0]: Documentation/devicetree/bindings/pwm/pwm.txt
+
+Example:
+
+ backlight {
+ compatible = "pwm-backlight";
+ pwms = <&pwm 0 5000000>;
+
+ brightness-levels = <0 4 8 16 32 64 128 255>;
+ default-brightness-level = <6>;

# Utilities
In 'mcX' directories are EDAC control and attribute files for
-this 'X' instance of the memory controllers:
-
-
-Counter reset control file:
-
- 'reset_counters'
-
- This write-only control file will zero all the statistical counters
- for UE and CE errors. Zeroing the counters will also reset the timer
- indicating how long since the last counter zero. This is useful
- for computing errors/time. Since the counters are always reset at
- driver initialization time, no module/kernel parameter is available.
-
- RUN TIME: echo "anything" >/sys/devices/system/edac/mc/mc0/counter_reset
-
- This resets the counters on memory controller 0
-
-
-Seconds since last counter reset control file:
-
- 'seconds_since_reset'
-
- This attribute file displays how many seconds have elapsed since the
- last counter reset. This can be used with the error counters to
- measure error rates.
-
-
-
-Memory Controller name attribute file:
-
- 'mc_name'
-
- This attribute file displays the type of memory controller
- that is being utilized.
-
-
-Total memory managed by this memory controller attribute file:
-
- 'size_mb'
-
- This attribute file displays, in count of megabytes, of memory
- that this instance of memory controller manages.
-
-
-Total Uncorrectable Errors count attribute file:
-
- 'ue_count'
-
- This attribute file displays the total count of uncorrectable
- errors that have occurred on this memory controller. If panic_on_ue
- is set this counter will not have a chance to increment,
- since EDAC will panic the system.
-
-
-Total UE count that had no information attribute fileY:
-
- 'ue_noinfo_count'
-
- This attribute file displays the number of UEs that have occurred
- with no information as to which DIMM slot is having errors.
-
-
-Total Correctable Errors count attribute file:
-
- 'ce_count'
-
- This attribute file displays the total count of correctable
- errors that have occurred on this memory controller. This
- count is very important to examine. CEs provide early
- indications that a DIMM is beginning to fail. This count
- field should be monitored for non-zero values and report
- such information to the system administrator.
-
-
-Total Correctable Errors count attribute file:
-
- 'ce_noinfo_count'
-
- This attribute file displays the number of CEs that
- have occurred wherewith no information as to which DIMM slot
- is having errors. Memory is handicapped, but operational,
- yet no information is available to indicate which slot
- the failing memory is in. This count field should be also
- be monitored for non-zero values.
-
-Device Symlink:
-
- 'device'
-
- Symlink to the memory controller device.
-
-Sdram memory scrubbing rate:
-
- 'sdram_scrub_rate'
-
- Read/Write attribute file that controls memory scrubbing. The scrubbing
- rate is set by writing a minimum bandwidth in bytes/sec to the attribute
- file. The rate will be translated to an internal value that gives at
- least the specified rate.
-
- Reading the file will return the actual scrubbing rate employed.
-
- If configuration fails or memory scrubbing is not implemented, accessing
- that attribute will fail.

+Notifier error injection
+========================
+
+Notifier error injection provides the ability to inject artifical errors to
+specified notifier chain callbacks. It is useful to test the error handling of
+notifier call chain failures which is rarely executed. There are kernel
+modules that can be used to test the following notifiers.
+
+ * CPU notifier
+ * PM notifier
+ * Memory hotplug notifier
+ * powerpc pSeries reconfig notifier
+
+CPU notifier error injection module
+-----------------------------------
+This feature can be used to test the error handling of the CPU notifiers by
+injecting artifical errors to CPU notifier chain callbacks.
+
+If the notifier call chain should be failed with some events notified, write
+the error code to debugfs interface
+/sys/kernel/debug/notifier-error-inject/cpu/actions/<notifier event>/error
+
+Possible CPU notifier events to be failed are:
+
+ * CPU_UP_PREPARE
+ * CPU_UP_PREPARE_FROZEN
+ * CPU_DOWN_PREPARE
+ * CPU_DOWN_PREPARE_FROZEN
+
+Example1: Inject CPU offline error (-1 == -EPERM)
+
+ # cd /sys/kernel/debug/notifier-error-inject/cpu
+ # echo -1 > actions/CPU_DOWN_PREPARE/error
+ # echo 0 > /sys/devices/system/cpu/cpu1/online
+ bash: echo: write error: Operation not permitted
+
+Example2: inject CPU online error (-2 == -ENOENT)
+
+ # echo -2 > actions/CPU_UP_PREPARE/error
+ # echo 1 > /sys/devices/system/cpu/cpu1/online
+ bash: echo: write error: No such file or directory
+
+PM notifier error injection module
+----------------------------------
+This feature is controlled through debugfs interface
+/sys/kernel/debug/notifier-error-inject/pm/actions/<notifier event>/error
+
+Possible PM notifier events to be failed are:
+
+ * PM_HIBERNATION_PREPARE
+ * PM_SUSPEND_PREPARE
+ * PM_RESTORE_PREPARE
+
+Example: Inject PM suspend error (-12 = -ENOMEM)
+
+ # cd /sys/kernel/debug/notifier-error-inject/pm/
+ # echo -12 > actions/PM_SUSPEND_PREPARE/error
+ # echo mem > /sys/power/state
+ bash: echo: write error: Cannot allocate memory
+
+Memory hotplug notifier error injection module
+----------------------------------------------
+This feature is controlled through debugfs interface
+/sys/kernel/debug/notifier-error-inject/memory/actions/<notifier event>/error
+
+Possible memory notifier events to be failed are:
+
+ * MEM_GOING_ONLINE
+ * MEM_GOING_OFFLINE
+
+Example: Inject memory hotplug offline error (-12 == -ENOMEM)
+
+ # cd /sys/kernel/debug/notifier-error-inject/memory
+ # echo -12 > actions/MEM_GOING_OFFLINE/error
+ # echo offline > /sys/devices/system/memory/memoryXXX/state
+ bash: echo: write error: Cannot allocate memory
+
+powerpc pSeries reconfig notifier error injection module
+--------------------------------------------------------
+This feature is controlled through debugfs interface
+/sys/kernel/debug/notifier-error-inject/pSeries-reconfig/actions/<notifier event>/error
+
+Possible pSeries reconfig notifier events to be failed are:
+
+ * PSERIES_RECONFIG_ADD
+ * PSERIES_RECONFIG_REMOVE
+ * PSERIES_DRCONF_MEM_ADD
+ * PSERIES_DRCONF_MEM_REMOVE
+
+For more usage examples
+-----------------------
+There are tools/testing/selftests using the notifier error injection features
+for CPU and memory notifiers.
+
+ * tools/testing/selftests/cpu-hotplug/on-off-test.sh
+ * tools/testing/selftests/memory-hotplug/on-off-test.sh
+
+These scripts first do simple online and offline tests and then do fault
+injection tests if notifier error injection module is available.

+EDT ft5x06 based Polytouch devices
+----------------------------------
+
+The edt-ft5x06 driver is useful for the EDT "Polytouch" family of capacitive
+touch screens. Note that it is *not* suitable for other devices based on the
+focaltec ft5x06 devices, since they contain vendor-specific firmware. In
+particular this driver is not suitable for the Nook tablet.
+
+It has been tested with the following devices:
+ * EP0350M06
+ * EP0430M06
+ * EP0570M06
+ * EP0700M06
+
+The driver allows configuration of the touch screen via a set of sysfs files:
+
+/sys/class/input/eventX/device/device/threshold:
+ allows setting the "click"-threshold in the range from 20 to 80.
+
+/sys/class/input/eventX/device/device/gain:
+ allows setting the sensitivity in the range from 0 to 31. Note that
+ lower values indicate higher sensitivity.
+
+/sys/class/input/eventX/device/device/offset:
+ allows setting the edge compensation in the range from 0 to 31.
+
+/sys/class/input/eventX/device/device/report_rate:
+ allows setting the report rate in the range from 3 to 14.
+
+
+For debugging purposes the driver provides a few files in the debug
+filesystem (if available in the kernel). In /sys/kernel/debug/edt_ft5x06
+you'll find the following files:
+
+num_x, num_y:
+ (readonly) contains the number of sensor fields in X- and
+ Y-direction.
+
+mode:
+ allows switching the sensor between "factory mode" and "operation
+ mode" by writing "1" or "0" to it. In factory mode (1) it is
+ possible to get the raw data from the sensor. Note that in factory
+ mode regular events don't get delivered and the options described
+ above are unavailable.
+
+raw_data:
+ contains num_x * num_y big endian 16 bit values describing the raw
+ values for each sensor field. Note that each read() call on this
+ files triggers a new readout. It is recommended to provide a buffer
+ big enough to contain num_x * num_y * 2 bytes.
+
+Note that reading raw_data gives a I/O error when the device is not in factory
+mode. The same happens when reading/writing to the parameter files when the
+device is not in regular operation mode.

+Pulse Width Modulation (PWM) interface
+
+This provides an overview about the Linux PWM interface
+
+PWMs are commonly used for controlling LEDs, fans or vibrators in
+cell phones. PWMs with a fixed purpose have no need implementing
+the Linux PWM API (although they could). However, PWMs are often
+found as discrete devices on SoCs which have no fixed purpose. It's
+up to the board designer to connect them to LEDs or fans. To provide
+this kind of flexibility the generic PWM API exists.
+
+Identifying PWMs
+----------------
+
+Users of the legacy PWM API use unique IDs to refer to PWM devices.
+
+Instead of referring to a PWM device via its unique ID, board setup code
+should instead register a static mapping that can be used to match PWM
+consumers to providers, as given in the following example:
+
+ static struct pwm_lookup board_pwm_lookup[] = {
+ PWM_LOOKUP("tegra-pwm", 0, "pwm-backlight", NULL),
+ };
+
+ static void __init board_init(void)
+ {
+ ...
+ pwm_add_table(board_pwm_lookup, ARRAY_SIZE(board_pwm_lookup));
+ ...
+ }
+
+Using PWMs
+----------
+
+Legacy users can request a PWM device using pwm_request() and free it
+after usage with pwm_free().
+
+New users should use the pwm_get() function and pass to it the consumer
+device or a consumer name. pwm_put() is used to free the PWM device.
+
+After being requested a PWM has to be configured using:
+
+int pwm_config(struct pwm_device *pwm, int duty_ns, int period_ns);
+
+To start/stop toggling the PWM output use pwm_enable()/pwm_disable().
+
+Implementing a PWM driver
+-------------------------
+
+Currently there are two ways to implement pwm drivers. Traditionally
+there only has been the barebone API meaning that each driver has
+to implement the pwm_*() functions itself. This means that it's impossible
+to have multiple PWM drivers in the system. For this reason it's mandatory
+for new drivers to use the generic PWM framework.
+
+A new PWM controller/chip can be added using pwmchip_add() and removed
+again with pwmchip_remove(). pwmchip_add() takes a filled in struct
+pwm_chip as argument which provides a description of the PWM chip, the
+number of PWM devices provider by the chip and the chip-specific
+implementation of the supported PWM operations to the framework.
+
+Locking
+-------
+
+The PWM core list manipulations are protected by a mutex, so pwm_request()
+and pwm_free() may not be called from an atomic context. Currently the
+PWM core does not enforce any locking to pwm_enable(), pwm_disable() and
+pwm_config(), so the calling context is currently driver specific. This
+is an issue derived from the former barebone API and should be fixed soon.
+
+Helpers
+-------
+
+Currently a PWM can only be configured with period_ns and duty_ns. For several
+use cases freq_hz and duty_percent might be better. Instead of calculating
+this in your driver please consider adding appropriate helpers to the framework.

+VFIO - "Virtual Function I/O"[1]
+-------------------------------------------------------------------------------
+Many modern system now provide DMA and interrupt remapping facilities
+to help ensure I/O devices behave within the boundaries they've been
+allotted. This includes x86 hardware with AMD-Vi and Intel VT-d,
+POWER systems with Partitionable Endpoints (PEs) and embedded PowerPC
+systems such as Freescale PAMU. The VFIO driver is an IOMMU/device
+agnostic framework for exposing direct device access to userspace, in
+a secure, IOMMU protected environment. In other words, this allows
+safe[2], non-privileged, userspace drivers.
+
+Why do we want that? Virtual machines often make use of direct device
+access ("device assignment") when configured for the highest possible
+I/O performance. From a device and host perspective, this simply
+turns the VM into a userspace driver, with the benefits of
+significantly reduced latency, higher bandwidth, and direct use of
+bare-metal device drivers[3].
+
+Some applications, particularly in the high performance computing
+field, also benefit from low-overhead, direct device access from
+userspace. Examples include network adapters (often non-TCP/IP based)
+and compute accelerators. Prior to VFIO, these drivers had to either
+go through the full development cycle to become proper upstream
+driver, be maintained out of tree, or make use of the UIO framework,
+which has no notion of IOMMU protection, limited interrupt support,
+and requires root privileges to access things like PCI configuration
+space.
+
+The VFIO driver framework intends to unify these, replacing both the
+KVM PCI specific device assignment code as well as provide a more
+secure, more featureful userspace driver environment than UIO.
+
+Groups, Devices, and IOMMUs
+-------------------------------------------------------------------------------
+
+Devices are the main target of any I/O driver. Devices typically
+create a programming interface made up of I/O access, interrupts,
+and DMA. Without going into the details of each of these, DMA is
+by far the most critical aspect for maintaining a secure environment
+as allowing a device read-write access to system memory imposes the
+greatest risk to the overall system integrity.
+
+To help mitigate this risk, many modern IOMMUs now incorporate
+isolation properties into what was, in many cases, an interface only
+meant for translation (ie. solving the addressing problems of devices
+with limited address spaces). With this, devices can now be isolated
+from each other and from arbitrary memory access, thus allowing
+things like secure direct assignment of devices into virtual machines.
+
+This isolation is not always at the granularity of a single device
+though. Even when an IOMMU is capable of this, properties of devices,
+interconnects, and IOMMU topologies can each reduce this isolation.
+For instance, an individual device may be part of a larger multi-
+function enclosure. While the IOMMU may be able to distinguish
+between devices within the enclosure, the enclosure may not require
+transactions between devices to reach the IOMMU. Examples of this
+could be anything from a multi-function PCI device with backdoors
+between functions to a non-PCI-ACS (Access Control Services) capable
+bridge allowing redirection without reaching the IOMMU. Topology
+can also play a factor in terms of hiding devices. A PCIe-to-PCI
+bridge masks the devices behind it, making transaction appear as if
+from the bridge itself. Obviously IOMMU design plays a major factor
+as well.
+
+Therefore, while for the most part an IOMMU may have device level
+granularity, any system is susceptible to reduced granularity. The
+IOMMU API therefore supports a notion of IOMMU groups. A group is
+a set of devices which is isolatable from all other devices in the
+system. Groups are therefore the unit of ownership used by VFIO.
+
+While the group is the minimum granularity that must be used to
+ensure secure user access, it's not necessarily the preferred
+granularity. In IOMMUs which make use of page tables, it may be
+possible to share a set of page tables between different groups,
+reducing the overhead both to the platform (reduced TLB thrashing,
+reduced duplicate page tables), and to the user (programming only
+a single set of translations). For this reason, VFIO makes use of
+a container class, which may hold one or more groups. A container
+is created by simply opening the /dev/vfio/vfio character device.
+
+On its own, the container provides little functionality, with all
+but a couple version and extension query interfaces locked away.
+The user needs to add a group into the container for the next level
+of functionality. To do this, the user first needs to identify the
+group associated with the desired device. This can be done using
+the sysfs links described in the example below. By unbinding the
+device from the host driver and binding it to a VFIO driver, a new
+VFIO group will appear for the group as /dev/vfio/$GROUP, where
+$GROUP is the IOMMU group number of which the device is a member.
+If the IOMMU group contains multiple devices, each will need to
+be bound to a VFIO driver before operations on the VFIO group
+are allowed (it's also sufficient to only unbind the device from
+host drivers if a VFIO driver is unavailable; this will make the
+group available, but not that particular device). TBD - interface
+for disabling driver probing/locking a device.
+
+Once the group is ready, it may be added to the container by opening
+the VFIO group character device (/dev/vfio/$GROUP) and using the
+VFIO_GROUP_SET_CONTAINER ioctl, passing the file descriptor of the
+previously opened container file. If desired and if the IOMMU driver
+supports sharing the IOMMU context between groups, multiple groups may
+be set to the same container. If a group fails to set to a container
+with existing groups, a new empty container will need to be used
+instead.
+
+With a group (or groups) attached to a container, the remaining
+ioctls become available, enabling access to the VFIO IOMMU interfaces.
+Additionally, it now becomes possible to get file descriptors for each
+device within a group using an ioctl on the VFIO group file descriptor.
+
+The VFIO device API includes ioctls for describing the device, the I/O
+regions and their read/write/mmap offsets on the device descriptor, as
+well as mechanisms for describing and registering interrupt
+notifications.
+
+VFIO Usage Example
+-------------------------------------------------------------------------------
+
+Assume user wants to access PCI device 0000:06:0d.0
+
+$ readlink /sys/bus/pci/devices/0000:06:0d.0/iommu_group
+../../../../kernel/iommu_groups/26
+
+This device is therefore in IOMMU group 26. This device is on the
+pci bus, therefore the user will make use of vfio-pci to manage the
+group:
+
+# modprobe vfio-pci
+
+Binding this device to the vfio-pci driver creates the VFIO group
+character devices for this group:
+
+$ lspci -n -s 0000:06:0d.0
+06:0d.0 0401: 1102:0002 (rev 08)
+# echo 0000:06:0d.0 > /sys/bus/pci/devices/0000:06:0d.0/driver/unbind
+# echo 1102 0002 > /sys/bus/pci/drivers/vfio/new_id
+
+Now we need to look at what other devices are in the group to free
+it for use by VFIO:
+
+$ ls -l /sys/bus/pci/devices/0000:06:0d.0/iommu_group/devices
+total 0
+lrwxrwxrwx. 1 root root 0 Apr 23 16:13 0000:00:1e.0 ->
+ ../../../../devices/pci0000:00/0000:00:1e.0
+lrwxrwxrwx. 1 root root 0 Apr 23 16:13 0000:06:0d.0 ->
+ ../../../../devices/pci0000:00/0000:00:1e.0/0000:06:0d.0
+lrwxrwxrwx. 1 root root 0 Apr 23 16:13 0000:06:0d.1 ->
+ ../../../../devices/pci0000:00/0000:00:1e.0/0000:06:0d.1
+
+This device is behind a PCIe-to-PCI bridge[4], therefore we also
+need to add device 0000:06:0d.1 to the group following the same
+procedure as above. Device 0000:00:1e.0 is a bridge that does
+not currently have a host driver, therefore it's not required to
+bind this device to the vfio-pci driver (vfio-pci does not currently
+support PCI bridges).
+
+The final step is to provide the user with access to the group if
+unprivileged operation is desired (note that /dev/vfio/vfio provides
+no capabilities on its own and is therefore expected to be set to

+
+VFIO bus driver API
+-------------------------------------------------------------------------------
+
+VFIO bus drivers, such as vfio-pci make use of only a few interfaces
+into VFIO core. When devices are bound and unbound to the driver,
+the driver should call vfio_add_group_dev() and vfio_del_group_dev()
+respectively:
+
+extern int vfio_add_group_dev(struct iommu_group *iommu_group,
+ struct device *dev,
+ const struct vfio_device_ops *ops,
+ void *device_data);
+
+extern void *vfio_del_group_dev(struct device *dev);
+
+vfio_add_group_dev() indicates to the core to begin tracking the
+specified iommu_group and register the specified dev as owned by
+a VFIO bus driver. The driver provides an ops structure for callbacks
+similar to a file operations structure:
+
+struct vfio_device_ops {
+ int (*open)(void *device_data);
+ void (*release)(void *device_data);
+ ssize_t (*read)(void *device_data, char __user *buf,
+ size_t count, loff_t *ppos);
+ ssize_t (*write)(void *device_data, const char __user *buf,
+ size_t size, loff_t *ppos);
+ long (*ioctl)(void *device_data, unsigned int cmd,
+ unsigned long arg);
+ int (*mmap)(void *device_data, struct vm_area_struct *vma);
+};
+
+Each function is passed the device_data that was originally registered
+in the vfio_add_group_dev() call above. This allows the bus driver
+an easy place to store its opaque, private data. The open/release
+callbacks are issued when a new file descriptor is created for a
+device (via VFIO_GROUP_GET_DEVICE_FD). The ioctl interface provides
+a direct pass through for VFIO_DEVICE_* ioctls. The read/write/mmap
+interfaces implement the device region access defined by the device's
+own VFIO_DEVICE_GET_REGION_INFO ioctl.
+
+-------------------------------------------------------------------------------
+
+[1] VFIO was originally an acronym for "Virtual Function I/O" in its
+initial implementation by Tom Lyon while as Cisco. We've since
+outgrown the acronym, but it's catchy.
+
+[2] "safe" also depends upon a device being "well behaved". It's
+possible for multi-function devices to have backdoors between
+functions and even for single function devices to have alternative
+access to things like PCI config space through MMIO registers. To
+guard against the former we can include additional precautions in the
+IOMMU driver to group multi-function PCI devices together
+(iommu=group_mf). The latter we can't prevent, but the IOMMU should
+still provide isolation. For PCI, SR-IOV Virtual Functions are the
+best indicator of "well behaved", as these are designed for
+virtualization usage models.
+
+[3] As always there are trade-offs to virtual machine device
+assignment that are beyond the scope of VFIO. It's expected that
+future IOMMU technologies will reduce some, but maybe not all, of
+these trade-offs.
+
+[4] In this case the device is below a PCI bridge, so transactions
+from either function of the device are indistinguishable to the iommu:

unlocked_ioctl file operation is called this lock will be taken by the
core and released afterwards. See the next section for more details.
+- queue: a pointer to the struct vb2_queue associated with this device node.
+ If queue is non-NULL, and queue->lock is non-NULL, then queue->lock is
+ used for the queuing ioctls (VIDIOC_REQBUFS, CREATE_BUFS, QBUF, DQBUF,
+ QUERYBUF, PREPARE_BUF, STREAMON and STREAMOFF) instead of the lock above.
+ That way the vb2 queuing framework does not have to wait for other ioctls.
+ This queue pointer is also used by the vb2 helper functions to check for
+ queuing ownership (i.e. is the filehandle calling it allowed to do the
+ operation).
+
- prio: keeps track of the priorities. Used to implement VIDIOC_G/S_PRIORITY.
If left to NULL, then it will use the struct v4l2_prio_state in v4l2_device.
If you want to have a separate priority state per (group of) device node(s),
A reference to the entity will be automatically acquired/released when the
video device is opened/closed.
-v4l2_file_operations and locking
---------------------------------
-
-You can set a pointer to a mutex_lock in struct video_device. Usually this
-will be either a top-level mutex or a mutex per device node. By default this
-lock will be used for unlocked_ioctl, but you can disable locking for
-selected ioctls by calling:
-
- void v4l2_disable_ioctl_locking(struct video_device *vdev, unsigned int cmd);
-
-E.g.: v4l2_disable_ioctl_locking(vdev, VIDIOC_DQBUF);
+ioctls and locking
+------------------
-You have to call this before you register the video_device.
+The V4L core provides optional locking services. The main service is the
+lock field in struct video_device, which is a pointer to a mutex. If you set
+this pointer, then that will be used by unlocked_ioctl to serialize all ioctls.
-Particularly with USB drivers where certain commands such as setting controls
-can take a long time you may want to do your own locking for the buffer queuing
-ioctls.
+If you are using the videobuf2 framework, then there is a second lock that you
+can set: video_device->queue->lock. If set, then this lock will be used instead
+of video_device->lock to serialize all queuing ioctls (see the previous section
+for the full list of those ioctls).
-If you want still finer-grained locking then you have to set mutex_lock to NULL
-and do you own locking completely.
+The advantage of using a different lock for the queuing ioctls is that for some
+drivers (particularly USB drivers) certain commands such as setting controls
+can take a long time, so you want to use a separate lock for the buffer queuing
+ioctls. That way your VIDIOC_DQBUF doesn't stall because the driver is busy
+changing the e.g. exposure of the webcam.
-It is up to the driver developer to decide which method to use. However, if
-your driver has high-latency operations (for example, changing the exposure
-of a USB webcam might take a long time), then you might be better off with
-doing your own locking if you want to allow the user to do other things with
-the device while waiting for the high-latency command to finish.
+Of course, you can always do all the locking yourself by leaving both lock
+pointers at NULL.
-If a lock is specified then all ioctl commands will be serialized on that
-lock. If you use videobuf then you must pass the same lock to the videobuf
-queue initialize function: if videobuf has to wait for a frame to arrive, then
-it will temporarily unlock the lock and relock it afterwards. If your driver
-also waits in the code, then you should do the same to allow other processes
-to access the device node while the first process is waiting for something.
+If you use the old videobuf then you must pass the video_device lock to the
+videobuf queue initialize function: if videobuf has to wait for a frame to
+arrive, then it will temporarily unlock the lock and relock it afterwards. If
+your driver also waits in the code, then you should do the same to allow other
+processes to access the device node while the first process is waiting for
+something.
In the case of videobuf2 you will need to implement the wait_prepare and
-wait_finish callbacks to unlock/lock if applicable. In particular, if you use
-the lock in struct video_device then you must unlock/lock this mutex in
-wait_prepare and wait_finish.
-
-The implementation of a hotplug disconnect should also take the lock before
-calling v4l2_device_disconnect.
+wait_finish callbacks to unlock/lock if applicable. If you use the queue->lock
+pointer, then you can use the helper functions vb2_ops_wait_prepare/finish.
+
+The implementation of a hotplug disconnect should also take the lock from
+video_device before calling v4l2_device_disconnect. If you are also using
+video_device->queue->lock, then you have to first lock video_device->queue->lock
+followed by video_device->lock. That way you can be sure no ioctl is running
+when you call v4l2_device_disconnect.

- * Spec
- *
- * memcpy copies len bytes from src to dst and sets v0 to dst.
- * It assumes that
- * - src and dst don't overlap
- * - src is readable
- * - dst is writable
- * memcpy uses the standard calling convention
- *
- * __copy_user copies up to len bytes from src to dst and sets a2 (len) to
- * the number of uncopied bytes due to an exception caused by a read or write.
- * __copy_user assumes that src and dst don't overlap, and that the call is
- * implementing one of the following:
- * copy_to_user
- * - src is readable (no exceptions when reading src)
- * copy_from_user
- * - dst is writable (no exceptions when writing dst)
- * __copy_user uses a non-standard calling convention; see
- * include/asm-mips/uaccess.h
- *
- * When an exception happens on a load, the handler must
- # ensure that all of the destination buffer is overwritten to prevent
- * leaking information to user mode programs.
- */
-
-/*
- * Implementation
- */
-
-/*
- * The exception handler for loads requires that:
- * 1- AT contain the address of the byte just past the end of the source
- * of the copy,
- * 2- src_entry <= src < AT, and
- * 3- (dst - src) == (dst_entry - src_entry),
- * The _entry suffix denotes values when __copy_user was called.
- *
- * (1) is set up up by uaccess.h and maintained by not writing AT in copy_user
- * (2) is met by incrementing src by the number of bytes copied
- * (3) is met by not doing loads between a pair of increments of dst and src
- *
- * The exception handlers for stores adjust len (if necessary) and return.
- * These handlers do not need to overwrite any data.
- *
- * For __rmemcpy and memmove an exception is always a kernel bug, therefore
- * they're not protected.

+ * void add_interrupt_randomness(int irq, int irq_flags);
* void add_disk_randomness(struct gendisk *disk);
*
+ * add_device_randomness() is for adding data to the random pool that
+ * is likely to differ between two devices (or possibly even per boot).
+ * This would be things like MAC addresses or serial numbers, or the
+ * read-out of the RTC. This does *not* add any actual entropy to the
+ * pool, but it initializes the pool to different values for devices
+ * that might otherwise be identical and have very little entropy
+ * available to them (particularly common in the embedded world).
+ *
* add_input_randomness() uses the input layer interrupt timing, as well as
* the event type information from the hardware.
*
- * add_interrupt_randomness() uses the inter-interrupt timing as random
- * inputs to the entropy pool. Note that not all interrupts are good
- * sources of randomness! For example, the timer interrupts is not a
- * good choice, because the periodicity of the interrupts is too
- * regular, and hence predictable to an attacker. Network Interface
- * Controller interrupts are a better measure, since the timing of the
- * NIC interrupts are more unpredictable.
+ * add_interrupt_randomness() uses the interrupt timing as random
+ * inputs to the entropy pool. Using the cycle counters and the irq source
+ * as inputs, it feeds the randomness roughly once a second.
*
* add_disk_randomness() uses what amounts to the seek time of block
* layer request events, on a per-disk_devt basis, as input to the

+ * reclaim). This is usually implemented by blocking new transactions for
+ * filesystems that have them and need this additional guard. After all

+ * flags = (DATA_NONE|ACTION_UNMASK), index = 0, start = 0, count = 1.
+ *
+ * DATA_BOOL allows sparse support for the same on arrays of interrupts.

+ * flags = (DATA_EVENTFD|ACTION_TRIGGER), index = 0, start = 0, count = 3,

+ * Once a signaling mechanism is set, DATA_BOOL or DATA_NONE can be used
+ * with ACTION_TRIGGER to perform kernel level interrupt loopback testing
+ * from userspace (ie. simulate hardware triggering).
+ *
+ * Setting of an event triggering mechanism to userspace for ACTION_TRIGGER
+ * enables the interrupt index for the device. Individual subindex interrupts
+ * can be disabled using the -1 value for DATA_EVENTFD or the index can be

+ * Floating proportions with flexible aging period
+ *
+ * Copyright (C) 2011, SUSE, Jan Kara <jack@suse.cz>
+ *
+ * The goal of this code is: Given different types of event, measure proportion
+ * of each type of event over time. The proportions are measured with
+ * exponentially decaying history to give smooth transitions. A formula
+ * expressing proportion of event of type 'j' is:
+ *
+ * p_{j} = (\Sum_{i>=0} x_{i,j}/2^{i+1})/(\Sum_{i>=0} x_i/2^{i+1})
+ *
+ * Where x_{i,j} is j's number of events in i-th last time period and x_i is
+ * total number of events in i-th last time period.
+ *
+ * Note that p_{j}'s are normalised, i.e.
+ *
+ * \Sum_{j} p_{j} = 1,
+ *
+ * This formula can be straightforwardly computed by maintaing denominator
+ * (let's call it 'd') and for each event type its numerator (let's call it
+ * 'n_j'). When an event of type 'j' happens, we simply need to do:
+ * n_j++; d++;
+ *
+ * When a new period is declared, we could do:
+ * d /= 2
+ * for each j
+ * n_j /= 2
+ *
+ * To avoid iteration over all event types, we instead shift numerator of event
+ * j lazily when someone asks for a proportion of event j or when event j
+ * occurs. This can bit trivially implemented by remembering last period in
+ * which something happened with proportion of type j.

+ tristate "IPv6: GRE tunnel"
+ select IPV6_TUNNEL
+ ---help---
+ Tunneling means encapsulating data of one protocol type within
+ another protocol and sending it over a channel that understands the
+ encapsulating protocol. This particular tunneling driver implements
+ GRE (Generic Routing Encapsulation) and at this time allows
+ encapsulating of IPv4 or IPv6 over existing IPv6 infrastructure.
+ This driver is useful if the other endpoint is a Cisco router: Cisco
+ likes GRE much better than the other Linux tunneling driver ("IP
+ tunneling" above). In addition, GRE allows multicast redistribution
+ through the tunnel.
+
+ Saying M here will produce a module called ip6_gre. If unsure, say N.
