2335 * The IPW device contains a Microwire compatible EEPROM that stores

2338 * device driver has sent the HostComplete command to the firmware) the
2339 * device driver has read access to the EEPROM by way of indirect addressing
2340 * through a couple of memory mapped registers.
2341 *
2342 * The following is a simplified implementation for pulling data out of the
2343 * the eeprom, along with some helper functions to find information in

3395 * Theory of operation
3396 *
3397 * A queue is a circular buffers with 'Read' and 'Write' pointers.
3398 * 2 empty entries always kept in the buffer to protect from overflow.
3399 *
3400 * For Tx queue, there are low mark and high mark limits. If, after queuing
Jeff Garzikbf794512005-07-31 13:07:26 -04003401 * the packet for Tx, free space become < low mark, Tx queue stopped. When
3402 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
James Ketrenos43f66a62005-03-25 12:31:53 -06003403 * Tx queue resumed.
3404 *
3405 * The IPW operates with six queues, one receive queue in the device's
3406 * sram, one transmit queue for sending commands to the device firmware,
Jeff Garzikbf794512005-07-31 13:07:26 -04003407 * and four transmit queues for data.
James Ketrenos43f66a62005-03-25 12:31:53 -06003408 *
Jeff Garzikbf794512005-07-31 13:07:26 -04003409 * The four transmit queues allow for performing quality of service (qos)
James Ketrenos43f66a62005-03-25 12:31:53 -06003410 * transmissions as per the 802.11 protocol. Currently Linux does not
Jeff Garzikbf794512005-07-31 13:07:26 -04003411 * provide a mechanism to the user for utilizing prioritized queues, so
James Ketrenos43f66a62005-03-25 12:31:53 -06003412 * we only utilize the first data transmit queue (queue1).

4741 *
4742 * The host allocates 32 DMA target addresses and passes the host address
James Ketrenosb095c382005-08-24 22:04:42 -05004743 * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
James Ketrenos43f66a62005-03-25 12:31:53 -06004744 * 0 to 31
4745 *
4746 * Rx Queue Indexes
4747 * The host/firmware share two index registers for managing the Rx buffers.
4748 *
Jeff Garzikbf794512005-07-31 13:07:26 -04004749 * The READ index maps to the first position that the firmware may be writing
4750 * to -- the driver can read up to (but not including) this position and get
4751 * good data.
James Ketrenos43f66a62005-03-25 12:31:53 -06004752 * The READ index is managed by the firmware once the card is enabled.
4753 *
4754 * The WRITE index maps to the last position the driver has read from -- the
4755 * position preceding WRITE is the last slot the firmware can place a packet.
4756 *
4757 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
Jeff Garzikbf794512005-07-31 13:07:26 -04004758 * WRITE = READ.
James Ketrenos43f66a62005-03-25 12:31:53 -06004759 *
Jeff Garzikbf794512005-07-31 13:07:26 -04004760 * During initialization the host sets up the READ queue position to the first
James Ketrenos43f66a62005-03-25 12:31:53 -06004761 * INDEX position, and WRITE to the last (READ - 1 wrapped)
4762 *
4763 * When the firmware places a packet in a buffer it will advance the READ index
4764 * and fire the RX interrupt. The driver can then query the READ index and
4765 * process as many packets as possible, moving the WRITE index forward as it
4766 * resets the Rx queue buffers with new memory.

James Ketrenos43f66a62005-03-25 12:31:53 -06004772 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
4773 * ipw->rxq is replenished and the READ INDEX is updated (updating the
4774 * 'processed' and 'read' driver indexes as well)
4775 * + A received packet is processed and handed to the kernel network stack,
4776 * detached from the ipw->rxq. The driver 'processed' index is updated.
4777 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
Jeff Garzikbf794512005-07-31 13:07:26 -04004778 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
4779 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
James Ketrenos43f66a62005-03-25 12:31:53 -06004780 * were enough free buffers and RX_STALLED is set it is cleared.
