-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.
-
The representation of the above is reflected in the directory tree
in EDAC's sysfs interface. Starting in directory
/sys/devices/system/edac/mc each memory controller will be represented
-by its own 'mcX' directory, where 'X" is the index of the MC.

-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,

+ * 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

+ * wrap the buffer pointer" cheaper in the assembly code which receives new
+ * buffers, and means that the value which defines the queue size,

+ * used in the packet_queue is already scaled by the size of a packet; here we

+ * @brief An object for specifying the characteristics of NetIO communication
+ * endpoint.
+ *
+ * @ingroup setup
+ *
+ * The @ref netio_input_register() function uses this structure to define
+ * how an application tile will communicate with an IPP.
+ *
+ *
+ * Future updates to NetIO may add new members to this structure,
+ * which can affect the success of the registration operation. Thus,
+ * if dynamically initializing the structure, applications are urged to
+ * zero it out first, for example:
+ *
+ * @code
+ * netio_input_config_t config;
+ * memset(&config, 0, sizeof (config));
+ * config.flags = NETIO_RECV | NETIO_XMIT_CSUM | NETIO_TAG_NONE;
+ * config.num_receive_packets = NETIO_MAX_RECEIVE_PKTS;
+ * config.queue_id = 0;
+ * .
+ * .
+ * .
+ * @endcode
+ *
+ * since that guarantees that any unused structure members, including
+ * members which did not exist when the application was first developed,
+ * will not have unexpected values.
+ *
+ * If statically initializing the structure, we strongly recommend use of
+ * C99-style named initializers, for example:
+ *
+ * @code
+ * netio_input_config_t config = {
+ * .flags = NETIO_RECV | NETIO_XMIT_CSUM | NETIO_TAG_NONE,
+ * .num_receive_packets = NETIO_MAX_RECEIVE_PKTS,
+ * .queue_id = 0,
+ * },
+ * @endcode
+ *
+ * instead of the old-style structure initialization:
+ *
+ * @code
+ * // Bad example! Currently equivalent to the above, but don't do this.
+ * netio_input_config_t config = {
+ * NETIO_RECV | NETIO_XMIT_CSUM | NETIO_TAG_NONE, NETIO_MAX_RECEIVE_PKTS, 0
+ * },
+ * @endcode
+ *
+ * since the C99 style requires no changes to the code if elements of the
+ * config structure are rearranged. (It also makes the initialization much
+ * easier to understand.)
+ *
+ * Except for items which address a particular tile's transmit or receive
+ * characteristics, such as the ::NETIO_RECV flag, applications are advised
+ * to specify the same set of configuration data on all registrations.
+ * This prevents differing results if multiple tiles happen to do their
+ * registration operations in a different order on different invocations of
+ * the application. This is particularly important for things like link
+ * management flags, and buffer size and homing specifications.
+ *
+ * Unless the ::NETIO_FIXED_BUFFER_VA flag is specified in flags, the NetIO
+ * buffer pool is automatically created and mapped into the application's
+ * virtual address space at an address chosen by the operating system,
+ * using the common memory (cmem) facility in the Tilera Multicore
+ * Components library. The cmem facility allows multiple processes to gain
+ * access to shared memory which is mapped into each process at an
+ * identical virtual address. In order for this to work, the processes
+ * must have a common ancestor, which must create the common memory using
+ * tmc_cmem_init().
+ *
+ * In programs using the iLib process creation API, or in programs which use
+ * only one process (which include programs using the pthreads library),
+ * tmc_cmem_init() is called automatically. All other applications
+ * must call it explicitly, before any child processes which might call
+ * netio_input_register() are created.
+ */
+typedef struct
+{
+ /** Registration characteristics.
+
+ This value determines several characteristics of the registration;
+ flags for different types of behavior are ORed together to make the
+ final flag value. Generally applications should specify exactly
+ one flag from each of the following categories:
+
+ - Whether the application will be receiving packets on this queue
+ (::NETIO_RECV or ::NETIO_NO_RECV).
+
+ - Whether the application will be transmitting packets on this queue,
+ and if so, whether it will request egress checksum calculation
+ (::NETIO_XMIT, ::NETIO_XMIT_CSUM, or ::NETIO_NO_XMIT). It is
+ legal to call netio_get_buffer() without one of the XMIT flags,
+ as long as ::NETIO_RECV is specified; in this case, the retrieved
+ buffers must be passed to another tile for transmission.
+
+ - Whether the application expects any vendor-specific tags in
+ its packets' L2 headers (::NETIO_TAG_NONE, ::NETIO_TAG_BRCM,
+ or ::NETIO_TAG_MRVL). This must match the configuration of the
+ target IPP.
+
+ To accommodate applications written to previous versions of the NetIO
+ interface, none of the flags above are currently required; if omitted,
+ NetIO behaves more or less as if ::NETIO_RECV | ::NETIO_XMIT_CSUM |
+ ::NETIO_TAG_NONE were used. However, explicit specification of
+ the relevant flags allows NetIO to do a better job of resource
+ allocation, allows earlier detection of certain configuration errors,
+ and may enable advanced features or higher performance in the future,
+ so their use is strongly recommended.
+
+ Note that specifying ::NETIO_NO_RECV along with ::NETIO_NO_XMIT
+ is a special case, intended primarily for use by programs which
+ retrieve network statistics or do link management operations.
+ When these flags are both specified, the resulting queue may not
+ be used with NetIO routines other than netio_get(), netio_set(),

+ This array specifies the relative amount of buffering to place

+ proportional to the amount of buffer space to allocate on that
+ node.
+
+ If memory striping is enabled in the Hypervisor, then there is
+ only one logical NUMA node (node 0). In that case, NetIO will by
+ default ignore the suggested buffer node weights, and buffers
+ will be striped across the physical memory controllers. See
+ UG209 System Programmer's Guide for a description of the
+ hypervisor option that controls memory striping.
+
+ If memory striping is disabled, then there are up to four NUMA
+ nodes, corresponding to the four DDRAM controllers in the TILE
+ processor architecture. See UG100 Tile Processor Architecture
+ Overview for a diagram showing the location of each of the DDRAM
+ controllers relative to the tile array.
+
+ For instance, if memory striping is disabled, the following

+
+ @code
+ netio_input_config_t config = {
+ .
+ .
+ .
+ .total_buffer_size = 4 * 16 * 1024 * 1024;

+ },
+ @endcode
+
+ would result in 32 MB of buffers being placed on controller 0, and
+ 32 MB on controller 2. (Since buffers are allocated in units of
+ 16 MB, some sets of weights will not be able to be matched exactly.)
+
+ For the weights to be effective, @ref total_buffer_size must be
+ nonzero. If @ref total_buffer_size is zero, causing the default
+ 32 MB of buffer space to be used, then any specified weights will
+ be ignored, and buffers will positioned as they were in previous
+ versions of NetIO:
+
+ - For xgbe/0 and gbe/0, 16 MB of buffers will be placed on controller 1,
+ and the other 16 MB will be placed on controller 2.
+
+ - For xgbe/1 and gbe/1, 16 MB of buffers will be placed on controller 2,
+ and the other 16 MB will be placed on controller 3.
+
+ If @ref total_buffer_size is nonzero, but all weights are zero,
+ then all buffer space will be allocated on Linux NUMA node zero.
+
+ By default, the specified buffer placement is treated as a hint;
+ if sufficient free memory is not available on the specified
+ controllers, the buffers will be allocated elsewhere. However,
+ if the ::NETIO_STRICT_HOMING flag is specified in @ref flags, then a
+ failure to allocate buffer space exactly as requested will cause the
+ registration operation to fail with an error of ::NETIO_CANNOT_HOME.

- 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.

+ * Then, "ifconfig DEVICE up" calls "tile_net_open()", which analyzes
+ * the network cpus, then uses "tile_net_open_aux()" to initialize
+ * LIPP/LEPP, and then uses "tile_net_open_inner()" to register all
+ * the tiles, provide buffers to LIPP, allow ingress to start, and
+ * turn on hypervisor interrupt handling (and NAPI) on all tiles.
+ *
+ * If registration fails due to the link being down, then "retry_work"
+ * is used to keep calling "tile_net_open_inner()" until it succeeds.
+ *
+ * If "ifconfig DEVICE down" is called, it uses "tile_net_stop()" to
+ * stop egress, drain the LIPP buffers, unregister all the tiles, stop
+ * LIPP/LEPP, and wipe the LEPP queue.
+ *
+ * We start out with the ingress interrupt enabled on each CPU. When
+ * this interrupt fires, we disable it, and call "napi_schedule()".
+ * This will cause "tile_net_poll()" to be called, which will pull
+ * packets from the netio queue, filtering them out, or passing them
+ * to "netif_receive_skb()". If our budget is exhausted, we will
+ * return, knowing we will be called again later. Otherwise, we
+ * reenable the ingress interrupt, and call "napi_complete()".
+ *
+ *
+ * NOTE: The use of "native_driver" ensures that EPP exists, and that
+ * "epp_sendv" is legal, and that "LIPP" is being used.
+ *
+ * NOTE: Failing to free completions for an arbitrarily long time
+ * (which is defined to be illegal) does in fact cause bizarre
+ * problems. The "egress_timer" helps prevent this from happening.
