-Device Interfaces
-
-Introduction
-~~~~~~~~~~~~
-
-Device interfaces are the logical interfaces of device classes that correlate
-directly to userspace interfaces, like device nodes. 
-   
-Each device class may have multiple interfaces through which you can 
-access the same device. An input device may support the mouse interface, 
-the 'evdev' interface, and the touchscreen interface. A SCSI disk would 
-support the disk interface, the SCSI generic interface, and possibly a raw 
-device interface. 
-
-Device interfaces are registered with the class they belong to. As devices
-are added to the class, they are added to each interface registered with
-the class. The interface is responsible for determining whether the device
-supports the interface or not. 
-
-
-Programming Interface
-~~~~~~~~~~~~~~~~~~~~~
-
-struct device_interface {
-       char                    * name;
-       rwlock_t                lock;
-       u32                     devnum;
-       struct device_class     * devclass;
-
-       struct list_head        node;
-       struct driver_dir_entry dir;
-
-       int (*add_device)(struct device *);
-       int (*add_device)(struct intf_data *);
-};
-
-int interface_register(struct device_interface *);
-void interface_unregister(struct device_interface *);
-
-
-An interface must specify the device class it belongs to. It is added
-to that class's list of interfaces on registration.
-
-
-Interfaces can be added to a device class at any time. Whenever it is
-added, each device in the class is passed to the interface's
-add_device callback. When an interface is removed, each device is
-removed from the interface.
-
-
-Devices
-~~~~~~~
-Once a device is added to a device class, it is added to each
-interface that is registered with the device class. The class
-is expected to place a class-specific data structure in 
-struct device::class_data. The interface can use that (along with
-other fields of struct device) to determine whether or not the driver
-and/or device support that particular interface.
-
-
-Data
-~~~~
-
-struct intf_data {
-       struct list_head        node;
-       struct device_interface * intf;
-       struct device           * dev;
-       u32                     intf_num;
-};
-
-int interface_add_data(struct interface_data *);
-
-The interface is responsible for allocating and initializing a struct 
-intf_data and calling interface_add_data() to add it to the device's list
-of interfaces it belongs to. This list will be iterated over when the device
-is removed from the class (instead of all possible interfaces for a class).
-This structure should probably be embedded in whatever per-device data 
-structure the interface is allocating anyway.
-   
-Devices are enumerated within the interface. This happens in interface_add_data()
-and the enumerated value is stored in the struct intf_data for that device. 
-
-sysfs
-~~~~~
-Each interface is given a directory in the directory of the device
-class it belongs to:
-
-Interfaces get a directory in the class's directory as well:
-
-   class/
-   `-- input
-       |-- devices
-       |-- drivers
-       |-- mouse
-       `-- evdev
-
-When a device is added to the interface, a symlink is created that points 
-to the device's directory in the physical hierarchy:
-
-   class/
-   `-- input
-       |-- devices
-       |   `-- 1 -> ../../../root/pci0/00:1f.0/usb_bus/00:1f.2-1:0/
-       |-- drivers
-       |   `-- usb:usb_mouse -> ../../../bus/drivers/usb_mouse/
-       |-- mouse

-Future Plans
-~~~~~~~~~~~~
-A device interface is correlated directly with a userspace interface
-for a device, specifically a device node. For instance, a SCSI disk
-exposes at least two interfaces to userspace: the standard SCSI disk
-interface and the SCSI generic interface. It might also export a raw
-device interface. 
-
-Many interfaces have a major number associated with them and each
-device gets a minor number. Or, multiple interfaces might share one
-major number, and each will receive a range of minor numbers (like in
-the case of input devices).
-
-These major and minor numbers could be stored in the interface
-structure. Major and minor allocations could happen when the interface
-is registered with the class, or via a helper function.

-   Instructions for use
-   --------------------
+   For usage instructions, please refer to:
 
-   1) Map a Linux block device to an existing rbd image.
-
-      Usage: <mon ip addr> <options> <pool name> <rbd image name> [snap name]
-
-      $ echo "192.168.0.1 name=admin rbd foo" > /sys/class/rbd/add
-
-      The snapshot name can be "-" or omitted to map the image read/write.
-
-   2) List all active blkdev<->object mappings.
-
-      In this example, we have performed step #1 twice, creating two blkdevs,
-      mapped to two separate rados objects in the rados rbd pool
-
-      $ cat /sys/class/rbd/list
-      #id     major   client_name     pool    name    snap    KB
-      0       254     client4143      rbd     foo     -      1024000
-
-      The columns, in order, are:
-      - blkdev unique id
-      - blkdev assigned major
-      - rados client id
-      - rados pool name
-      - rados block device name
-      - mapped snapshot ("-" if none)
-      - device size in KB
-
-
-   3) Create a snapshot.
-
-      Usage: <blkdev id> <snapname>
-
-      $ echo "0 mysnap" > /sys/class/rbd/snap_create
-
-
-   4) Listing a snapshot.
-
-      $ cat /sys/class/rbd/snaps_list
-      #id     snap    KB
-      0       -       1024000 (*)
-      0       foo     1024000
-
-      The columns, in order, are:
-      - blkdev unique id
-      - snapshot name, '-' means none (active read/write version)
-      - size of device at time of snapshot
-      - the (*) indicates this is the active version
-
-   5) Rollback to snapshot.
-
-      Usage: <blkdev id> <snapname>
-
-      $ echo "0 mysnap" > /sys/class/rbd/snap_rollback
-
-
-   6) Mapping an image using snapshot.
-
-      A snapshot mapping is read-only. This is being done by passing
-      snap=<snapname> to the options when adding a device.
-
-      $ echo "192.168.0.1 name=admin,snap=mysnap rbd foo" > /sys/class/rbd/add
-
-
-   7) Remove an active blkdev<->rbd image mapping.
-
-      In this example, we remove the mapping with blkdev unique id 1.
-
-      $ echo 1 > /sys/class/rbd/remove
-
-
-   NOTE:  The actual creation and deletion of rados objects is outside the scope
-   of this driver.
