 * This event is sent when the stack receives an incoming request to an address

 *
 * The payload data for requests carrying data (write and lock requests)

 *
 * Unlike &fw_cdev_event_request, @tcode of lock requests is one of the

 *
 * @card may differ from &fw_cdev_get_info.card because requests are received

 * therefore differ from the corresponding fields of the last
 * &fw_cdev_event_bus_reset.
 *
 * @destination_node_id may also differ from the current node ID because of a
 * non-local bus ID part or in case of a broadcast write request.  Note, a
 * client must call an %FW_CDEV_IOC_SEND_RESPONSE ioctl even in case of a
 * broadcast write request; the kernel will then release the kernel-side pending
 * request but will not actually send a response packet.
 *
 * In case of a write request to FCP_REQUEST or FCP_RESPONSE, the kernel already
 * sent a write response immediately after the request was received; in this
 * case the client must still call an %FW_CDEV_IOC_SEND_RESPONSE ioctl to
 * release the kernel-side pending request, though another response won't be
 * sent.
 *
 * If the client subsequently needs to initiate requests to the sender node of
 * an &fw_cdev_event_request2, it needs to use a device file with matching

 * @cycle:	Cycle counter of the last completed packet
 * @header_length: Total length of following headers, in bytes
 * @header:	Stripped headers, if any
 *
 * This event is sent when the controller has completed an &fw_cdev_iso_packet
 * with the %FW_CDEV_ISO_INTERRUPT bit set, when explicitly requested with
 * %FW_CDEV_IOC_FLUSH_ISO, or when there have been so many completed packets
 * without the interrupt bit set that the kernel's internal buffer for @header
 * is about to overflow.  (In the last case, ABI versions < 5 drop header data
 * up to the next interrupt packet.)
 *
 * Isochronous transmit events (context type %FW_CDEV_ISO_CONTEXT_TRANSMIT):
 *
 * In version 3 and some implementations of version 2 of the ABI, &header_length
 * is a multiple of 4 and &header contains timestamps of all packets up until
 * the interrupt packet.  The format of the timestamps is as described below for
 * isochronous reception.  In version 1 of the ABI, &header_length was 0.
 *
 * Isochronous receive events (context type %FW_CDEV_ISO_CONTEXT_RECEIVE):
 *
 * The headers stripped of all packets up until and including the interrupt
 * packet are returned in the @header field.  The amount of header data per
 * packet is as specified at iso context creation by
 * &fw_cdev_create_iso_context.header_size.
 *
 * Hence, _interrupt.header_length / _context.header_size is the number of
 * packets received in this interrupt event.  The client can now iterate
 * through the mmap()'ed DMA buffer according to this number of packets and
 * to the buffer sizes as the client specified in &fw_cdev_queue_iso.
 *
 * Since version 2 of this ABI, the portion for each packet in _interrupt.header
 * consists of the 1394 isochronous packet header, followed by a timestamp
 * quadlet if &fw_cdev_create_iso_context.header_size > 4, followed by quadlets
 * from the packet payload if &fw_cdev_create_iso_context.header_size > 8.
 *
 * Format of 1394 iso packet header:  16 bits data_length, 2 bits tag, 6 bits
 * channel, 4 bits tcode, 4 bits sy, in big endian byte order.
 * data_length is the actual received size of the packet without the four
 * 1394 iso packet header bytes.
 *
 * Format of timestamp:  16 bits invalid, 3 bits cycleSeconds, 13 bits
 * cycleCount, in big endian byte order.
 *
 * In version 1 of the ABI, no timestamp quadlet was inserted; instead, payload
 * data followed directly after the 1394 is header if header_size > 4.
 * Behaviour of ver. 1 of this ABI is no longer available since ABI ver. 2.

 * The buffer is continuously filled with the following data, per packet:
 *  - the 1394 iso packet header as described at &fw_cdev_event_iso_interrupt,
 *    but in little endian byte order,
 *  - packet payload (as many bytes as specified in the data_length field of

 *  - 0...3 padding bytes as needed to align the following trailer quadlet,
 *  - trailer quadlet, containing the reception timestamp as described at

 *
 * Hence the per-packet size is data_length (rounded up to a multiple of 4) + 8.

/**
 * struct fw_cdev_allocate_iso_resource - (De)allocate a channel or bandwidth
 * @closure:	Passed back to userspace in corresponding iso resource events

 * @bandwidth:	Isochronous bandwidth units to be (de)allocated
 * @handle:	Handle to the allocation, written by the kernel (only valid in
 *		case of %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE ioctls)
 *
 * The %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE ioctl initiates allocation of an
 * isochronous channel and/or of isochronous bandwidth at the isochronous
 * resource manager (IRM).  Only one of the channels specified in @channels is
 * allocated.  An %FW_CDEV_EVENT_ISO_RESOURCE_ALLOCATED is sent after
 * communication with the IRM, indicating success or failure in the event data.
 * The kernel will automatically reallocate the resources after bus resets.
 * Should a reallocation fail, an %FW_CDEV_EVENT_ISO_RESOURCE_DEALLOCATED event
 * will be sent.  The kernel will also automatically deallocate the resources
 * when the file descriptor is closed.
 *
 * The %FW_CDEV_IOC_DEALLOCATE_ISO_RESOURCE ioctl can be used to initiate
 * deallocation of resources which were allocated as described above.
 * An %FW_CDEV_EVENT_ISO_RESOURCE_DEALLOCATED event concludes this operation.
 *
 * The %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE_ONCE ioctl is a variant of allocation
 * without automatic re- or deallocation.
 * An %FW_CDEV_EVENT_ISO_RESOURCE_ALLOCATED event concludes this operation,
 * indicating success or failure in its data.
 *
 * The %FW_CDEV_IOC_DEALLOCATE_ISO_RESOURCE_ONCE ioctl works like
 * %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE_ONCE except that resources are freed
 * instead of allocated.
 * An %FW_CDEV_EVENT_ISO_RESOURCE_DEALLOCATED event concludes this operation.
 *
 * To summarize, %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE allocates iso resources
 * for the lifetime of the fd or @handle.
 * In contrast, %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE_ONCE allocates iso resources
 * for the duration of a bus generation.
 *
 * @channels is a host-endian bitfield with the least significant bit
 * representing channel 0 and the most significant bit representing channel 63:
 * 1ULL << c for each channel c that is a candidate for (de)allocation.
 *
 * @bandwidth is expressed in bandwidth allocation units, i.e. the time to send
 * one quadlet of data (payload or header data) at speed S1600.
