3417 *
3418 * Theory of operation
3419 *
3420 * A queue is a circular buffers with 'Read' and 'Write' pointers.
3421 * 2 empty entries always kept in the buffer to protect from overflow.
3422 *
3423 * For Tx queue, there are low mark and high mark limits. If, after queuing
Jeff Garzikbf794512005-07-31 13:07:26 -04003424 * the packet for Tx, free space become < low mark, Tx queue stopped. When
3425 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
James Ketrenos43f66a62005-03-25 12:31:53 -06003426 * Tx queue resumed.
3427 *
3428 * The IPW operates with six queues, one receive queue in the device's
3429 * sram, one transmit queue for sending commands to the device firmware,
Jeff Garzikbf794512005-07-31 13:07:26 -04003430 * and four transmit queues for data.
James Ketrenos43f66a62005-03-25 12:31:53 -06003431 *
Jeff Garzikbf794512005-07-31 13:07:26 -04003432 * The four transmit queues allow for performing quality of service (qos)
James Ketrenos43f66a62005-03-25 12:31:53 -06003433 * transmissions as per the 802.11 protocol. Currently Linux does not
Jeff Garzikbf794512005-07-31 13:07:26 -04003434 * provide a mechanism to the user for utilizing prioritized queues, so
James Ketrenos43f66a62005-03-25 12:31:53 -06003435 * we only utilize the first data transmit queue (queue1).

4752 *
4753 * The host allocates 32 DMA target addresses and passes the host address
James Ketrenosb095c382005-08-24 22:04:42 -05004754 * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is

4756 *
4757 * Rx Queue Indexes
4758 * The host/firmware share two index registers for managing the Rx buffers.
4759 *
Jeff Garzikbf794512005-07-31 13:07:26 -04004760 * The READ index maps to the first position that the firmware may be writing
4761 * to -- the driver can read up to (but not including) this position and get
4762 * good data.
James Ketrenos43f66a62005-03-25 12:31:53 -06004763 * The READ index is managed by the firmware once the card is enabled.
4764 *
4765 * The WRITE index maps to the last position the driver has read from -- the
4766 * position preceding WRITE is the last slot the firmware can place a packet.
4767 *
4768 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
Jeff Garzikbf794512005-07-31 13:07:26 -04004769 * WRITE = READ.
James Ketrenos43f66a62005-03-25 12:31:53 -06004770 *
Jeff Garzikbf794512005-07-31 13:07:26 -04004771 * During initialization the host sets up the READ queue position to the first
James Ketrenos43f66a62005-03-25 12:31:53 -06004772 * INDEX position, and WRITE to the last (READ - 1 wrapped)
4773 *
4774 * When the firmware places a packet in a buffer it will advance the READ index
4775 * and fire the RX interrupt. The driver can then query the READ index and
4776 * process as many packets as possible, moving the WRITE index forward as it
4777 * resets the Rx queue buffers with new memory.

James Ketrenos43f66a62005-03-25 12:31:53 -06004783 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
4784 * ipw->rxq is replenished and the READ INDEX is updated (updating the
4785 * 'processed' and 'read' driver indexes as well)
4786 * + A received packet is processed and handed to the kernel network stack,
4787 * detached from the ipw->rxq. The driver 'processed' index is updated.
4788 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
Jeff Garzikbf794512005-07-31 13:07:26 -04004789 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
