3421 | * A queue is a circular buffers with 'Read' and 'Write' pointers. | |
3422 | * 2 empty entries always kept in the buffer to protect from overflow. | |
3423 | * | |
3424 | * For Tx queue, there are low mark and high mark limits. If, after queuing | |
bf79451e JG |
3425 | * the packet for Tx, free space become < low mark, Tx queue stopped. When |
3426 | * reclaiming packets (on 'tx done IRQ), if free space become > high mark, | |
43f66a6c JK |
3427 | * Tx queue resumed. |
3428 | * | |
3429 | * The IPW operates with six queues, one receive queue in the device's | |
3430 | * sram, one transmit queue for sending commands to the device firmware, | |
bf79451e | 3431 | * and four transmit queues for data. |
43f66a6c | 3432 | * |
bf79451e | 3433 | * The four transmit queues allow for performing quality of service (qos) |
43f66a6c | 3434 | * transmissions as per the 802.11 protocol. Currently Linux does not |
bf79451e | 3435 | * provide a mechanism to the user for utilizing prioritized queues, so |

4765 | * Rx theory of operation |
4766 | * | |
4767 | * The host allocates 32 DMA target addresses and passes the host address | |
b095c381 | 4768 | * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is |
43f66a6c JK |
4769 | * 0 to 31 |
4770 | * | |
4771 | * Rx Queue Indexes | |
4772 | * The host/firmware share two index registers for managing the Rx buffers. | |
4773 | * | |
bf79451e JG |
4774 | * The READ index maps to the first position that the firmware may be writing |
4775 | * to -- the driver can read up to (but not including) this position and get | |
4776 | * good data. | |
43f66a6c JK |
4777 | * The READ index is managed by the firmware once the card is enabled. |
4778 | * | |
4779 | * The WRITE index maps to the last position the driver has read from -- the | |
4780 | * position preceding WRITE is the last slot the firmware can place a packet. | |
4781 | * | |
4782 | * The queue is empty (no good data) if WRITE = READ - 1, and is full if | |
bf79451e | 4783 | * WRITE = READ. |
43f66a6c | 4784 | * |
bf79451e | 4785 | * During initialization the host sets up the READ queue position to the first |
43f66a6c JK |
4786 | * INDEX position, and WRITE to the last (READ - 1 wrapped) |
4787 | * | |
4788 | * When the firmware places a packet in a buffer it will advance the READ index | |
4789 | * and fire the RX interrupt. The driver can then query the READ index and | |
4790 | * process as many packets as possible, moving the WRITE index forward as it | |
4791 | * resets the Rx queue buffers with new memory. | |
bf79451e | 4792 | * |
43f66a6c | 4793 | * The management in the driver is as follows: |
bf79451e | 4794 | * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When |
43f66a6c | 4795 | * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled |
bf79451e | 4796 | * to replensish the ipw->rxq->rx_free. |
43f66a6c JK |
4797 | * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the |
4798 | * ipw->rxq is replenished and the READ INDEX is updated (updating the | |
4799 | * 'processed' and 'read' driver indexes as well) | |
4800 | * + A received packet is processed and handed to the kernel network stack, | |
4801 | * detached from the ipw->rxq. The driver 'processed' index is updated. | |
4802 | * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free | |
bf79451e JG |
4803 | * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ |
4804 | * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there | |
43f66a6c JK |
4805 | * were enough free buffers and RX_STALLED is set it is cleared. |
4806 | * | |
