4617 | * Rx theory of operation |
4618 | * | |
4619 | * The host allocates 32 DMA target addresses and passes the host address | |
b095c381 | 4620 | * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is |
43f66a6c JK |
4621 | * 0 to 31 |
4622 | * | |
4623 | * Rx Queue Indexes | |
4624 | * The host/firmware share two index registers for managing the Rx buffers. | |
4625 | * | |
bf79451e JG |
4626 | * The READ index maps to the first position that the firmware may be writing |
4627 | * to -- the driver can read up to (but not including) this position and get | |
4628 | * good data. | |
43f66a6c JK |
4629 | * The READ index is managed by the firmware once the card is enabled. |
4630 | * | |
4631 | * The WRITE index maps to the last position the driver has read from -- the | |
4632 | * position preceding WRITE is the last slot the firmware can place a packet. | |
4633 | * | |
4634 | * The queue is empty (no good data) if WRITE = READ - 1, and is full if | |
bf79451e | 4635 | * WRITE = READ. |
43f66a6c | 4636 | * |
bf79451e | 4637 | * During initialization the host sets up the READ queue position to the first |
43f66a6c JK |
4638 | * INDEX position, and WRITE to the last (READ - 1 wrapped) |
4639 | * | |
4640 | * When the firmware places a packet in a buffer it will advance the READ index | |
4641 | * and fire the RX interrupt. The driver can then query the READ index and | |
4642 | * process as many packets as possible, moving the WRITE index forward as it | |
4643 | * resets the Rx queue buffers with new memory. | |
bf79451e | 4644 | * |
43f66a6c | 4645 | * The management in the driver is as follows: |
bf79451e | 4646 | * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When |
43f66a6c | 4647 | * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled |
bf79451e | 4648 | * to replensish the ipw->rxq->rx_free. |
43f66a6c JK |
4649 | * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the |
4650 | * ipw->rxq is replenished and the READ INDEX is updated (updating the | |
4651 | * 'processed' and 'read' driver indexes as well) | |
4652 | * + A received packet is processed and handed to the kernel network stack, | |
4653 | * detached from the ipw->rxq. The driver 'processed' index is updated. | |
4654 | * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free | |
bf79451e JG |
4655 | * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ |
4656 | * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there | |
43f66a6c JK |
4657 | * were enough free buffers and RX_STALLED is set it is cleared. |
4658 | * | |
4659 | * | |
4660 | * Driver sequence: | |
4661 | * | |
bf79451e | 4662 | * ipw_rx_queue_alloc() Allocates rx_free |
43f66a6c JK |
4663 | * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls |
4664 | * ipw_rx_queue_restock | |
4665 | * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx | |
4666 | * queue, updates firmware pointers, and updates | |
4667 | * the WRITE index. If insufficient rx_free buffers | |
4668 | * are available, schedules ipw_rx_queue_replenish | |
4669 | * | |
4670 | * -- enable interrupts -- | |
4671 | * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the | |
bf79451e | 4672 | * READ INDEX, detaching the SKB from the pool. |
43f66a6c JK |
