What: /sys/bus/rbd/
Date: November 2010
Contact: Yehuda Sadeh <yehuda@hq.newdream.net>,
Sage Weil <sage@newdream.net>
Description:
Being used for adding and removing rbd block devices.
Usage: <mon ip addr> <options> <pool name> <rbd image name> [snap name]
$ echo "192.168.0.1 name=admin rbd foo" > /sys/bus/rbd/add
The snapshot name can be "-" or omitted to map the image read/write. A <dev-id>
will be assigned for any registered block device. If snapshot is used, it will
be mapped read-only.
Removal of a device:
$ echo <dev-id> > /sys/bus/rbd/remove
Entries under /sys/bus/rbd/devices/<dev-id>/
--------------------------------------------
client_id
The ceph unique client id that was assigned for this specific session.
major
The block device major number.
name
The name of the rbd image.
pool
The pool where this rbd image resides. The pool-name pair is unique
per rados system.
size
The size (in bytes) of the mapped block device.
refresh
Writing to this file will reread the image header data and set
all relevant datastructures accordingly.
current_snap
The current snapshot for which the device is mapped.
create_snap
Create a snapshot:
$ echo <snap-name> > /sys/bus/rbd/devices/<dev-id>/snap_create
rollback_snap
Rolls back data to the specified snapshot. This goes over the entire
list of rados blocks and sends a rollback command to each.
$ echo <snap-name> > /sys/bus/rbd/devices/<dev-id>/snap_rollback
snap_*
A directory per each snapshot
Entries under /sys/bus/rbd/devices/<dev-id>/snap_<snap-name>
-------------------------------------------------------------
id
The rados internal snapshot id assigned for this snapshot
size
The size of the image when this snapshot was taken.

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.

Clock framework on SuperH architecture
The framework on SH extends existing API by the function clk_set_rate_ex,
which prototype is as follows:
clk_set_rate_ex (struct clk *clk, unsigned long rate, int algo_id)
The algo_id parameter is used to specify algorithm used to recalculate clocks,
adjanced to clock, specified as first argument. It is assumed that algo_id==0
means no changes to adjanced clock
Internally, the clk_set_rate_ex forwards request to clk->ops->set_rate method,
if it is present in ops structure. The method should set the clock rate and adjust
all needed clocks according to the passed algo_id.
Exact values for algo_id are machine-dependent. For the sh7722, the following
values are defined:
NO_CHANGE = 0,
IUS_N1_N1, /* I:U = N:1, U:Sh = N:1 */
IUS_322, /* I:U:Sh = 3:2:2 */
IUS_522, /* I:U:Sh = 5:2:2 */
IUS_N11, /* I:U:Sh = N:1:1 */
SB_N1, /* Sh:B = N:1 */
SB3_N1, /* Sh:B3 = N:1 */
SB3_32, /* Sh:B3 = 3:2 */
SB3_43, /* Sh:B3 = 4:3 */
SB3_54, /* Sh:B3 = 5:4 */
BP_N1, /* B:P = N:1 */
IP_N1 /* I:P = N:1 */
Each of these constants means relation between clocks that can be set via the FRQCR
register

* slots are invalid (do not contain a packet).

/** A queue of buffers.
*
* This structure partially defines a queue of empty buffers which have been
* obtained via requests to the IPP. (The elements of the queue are packet
* handles, which are transformed into a full netio_pkt_t when the buffer is
* retrieved.) The queue as a whole is written to by an interrupt handler and
* read by non-interrupt code; this data structure is what's touched by the
* interrupt handler. The other parts of the queue state, the read offset and
* requested write offset, are kept in user space, not in hypervisor space, so
* they are in a separate data structure.
*
* The read offset (__buffer_read in the user part of the queue structure)
* points to the next buffer to be read. When the read offset is equal to the
* write offset, the queue is empty; therefore the queue must contain one more
* slot than the required maximum queue size.
*
* The requested write offset (__buffer_requested_write in the user part of
* the queue structure) points to the slot which will hold the next buffer we
* request from the IPP, once we get around to sending such a request. When
* the requested write offset is equal to the write offset, no requests for
* new buffers are outstanding; when the requested write offset is one greater
* than the read offset, no more requests may be sent.
*
* Note that, unlike the packet_queue, the buffer_queue places incoming
* buffers at decreasing addresses. This makes the check for "is it time to
* wrap the buffer pointer" cheaper in the assembly code which receives new
* buffers, and means that the value which defines the queue size,
* __last_buffer, is different than in the packet queue. Also, the offset
* used in the packet_queue is already scaled by the size of a packet; here we
* use unscaled slot indices for the offsets. (These differences are
* historical, and in the future it's possible that the packet_queue will look
* more like this queue.)
*
* @code
* Here's an example of all 4 state variables and what they mean. Remember:
* all pointers move right to left.
*
* V V V I I R R V V V
* 0 1 2 3 4 5 6 7 8 9

* | | | __last_buffer
* | | __buffer_write

* __buffer_read
* @endcode
*
* This queue has 10 slots, and thus can hold 9 buffers (_last_buffer = 9).
* The read pointer is at 2, and the write pointer is at 6; thus, there are
* valid, unread buffers in slots 2, 1, 0, 9, 8, and 7. The requested write
* pointer is at 4; thus, requests have been made to the IPP for buffers which
* will be placed in slots 6 and 5 when they arrive. Finally, the remaining
* slots are invalid (do not contain a buffer).
