3588 *
3589 * Theory of operation
3590 *
3591 * A queue is a circular buffers with 'Read' and 'Write' pointers.
3592 * 2 empty entries always kept in the buffer to protect from overflow.
3593 *
3594 * For Tx queue, there are low mark and high mark limits. If, after queuing
Jeff Garzikbf794512005-07-31 13:07:26 -04003595 * the packet for Tx, free space become < low mark, Tx queue stopped. When
3596 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
James Ketrenos43f66a62005-03-25 12:31:53 -06003597 * Tx queue resumed.
3598 *
3599 * The IPW operates with six queues, one receive queue in the device's
3600 * sram, one transmit queue for sending commands to the device firmware,
Jeff Garzikbf794512005-07-31 13:07:26 -04003601 * and four transmit queues for data.
James Ketrenos43f66a62005-03-25 12:31:53 -06003602 *
Jeff Garzikbf794512005-07-31 13:07:26 -04003603 * The four transmit queues allow for performing quality of service (qos)
James Ketrenos43f66a62005-03-25 12:31:53 -06003604 * transmissions as per the 802.11 protocol. Currently Linux does not
Jeff Garzikbf794512005-07-31 13:07:26 -04003605 * provide a mechanism to the user for utilizing prioritized queues, so
James Ketrenos43f66a62005-03-25 12:31:53 -06003606 * we only utilize the first data transmit queue (queue1).

5019 *
5020 * Rx Queue Indexes
5021 * The host/firmware share two index registers for managing the Rx buffers.
5022 *
Jeff Garzikbf794512005-07-31 13:07:26 -04005023 * The READ index maps to the first position that the firmware may be writing
5024 * to -- the driver can read up to (but not including) this position and get
5025 * good data.
James Ketrenos43f66a62005-03-25 12:31:53 -06005026 * The READ index is managed by the firmware once the card is enabled.
5027 *
5028 * The WRITE index maps to the last position the driver has read from -- the
5029 * position preceding WRITE is the last slot the firmware can place a packet.
5030 *
5031 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
Jeff Garzikbf794512005-07-31 13:07:26 -04005032 * WRITE = READ.
James Ketrenos43f66a62005-03-25 12:31:53 -06005033 *
Jeff Garzikbf794512005-07-31 13:07:26 -04005034 * During initialization the host sets up the READ queue position to the first
James Ketrenos43f66a62005-03-25 12:31:53 -06005035 * INDEX position, and WRITE to the last (READ - 1 wrapped)
5036 *
5037 * When the firmware places a packet in a buffer it will advance the READ index
5038 * and fire the RX interrupt. The driver can then query the READ index and
5039 * process as many packets as possible, moving the WRITE index forward as it
5040 * resets the Rx queue buffers with new memory.

James Ketrenos43f66a62005-03-25 12:31:53 -06005046 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
5047 * ipw->rxq is replenished and the READ INDEX is updated (updating the
5048 * 'processed' and 'read' driver indexes as well)
5049 * + A received packet is processed and handed to the kernel network stack,
5050 * detached from the ipw->rxq. The driver 'processed' index is updated.
5051 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
Jeff Garzikbf794512005-07-31 13:07:26 -04005052 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
