-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
- | `-- 1 -> ../../../root/pci0/00:1f.0/usb_bus/00:1f.2-1:0/
- `-- evdev
- `-- 1 -> ../../../root/pci0/00:1f.0/usb_bus/00:1f.2-1:0/
-
-
-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.
