5023 | * Rx theory of operation |
5024 | * | |
5025 | * The host allocates 32 DMA target addresses and passes the host address | |
b095c381 | 5026 | * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is |
43f66a6c JK |
5027 | * 0 to 31 |
5028 | * | |
5029 | * Rx Queue Indexes | |
5030 | * The host/firmware share two index registers for managing the Rx buffers. | |
5031 | * | |
bf79451e JG |
5032 | * The READ index maps to the first position that the firmware may be writing |
5033 | * to -- the driver can read up to (but not including) this position and get | |
5034 | * good data. | |
43f66a6c JK |
5035 | * The READ index is managed by the firmware once the card is enabled. |
5036 | * | |
5037 | * The WRITE index maps to the last position the driver has read from -- the | |
5038 | * position preceding WRITE is the last slot the firmware can place a packet. | |
5039 | * | |
5040 | * The queue is empty (no good data) if WRITE = READ - 1, and is full if | |
bf79451e | 5041 | * WRITE = READ. |
43f66a6c | 5042 | * |
bf79451e | 5043 | * During initialization the host sets up the READ queue position to the first |
43f66a6c JK |
5044 | * INDEX position, and WRITE to the last (READ - 1 wrapped) |
5045 | * | |
5046 | * When the firmware places a packet in a buffer it will advance the READ index | |
5047 | * and fire the RX interrupt. The driver can then query the READ index and | |
5048 | * process as many packets as possible, moving the WRITE index forward as it | |
5049 | * resets the Rx queue buffers with new memory. | |
bf79451e | 5050 | * |
43f66a6c | 5051 | * The management in the driver is as follows: |
bf79451e | 5052 | * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When |
43f66a6c | 5053 | * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled |
bf79451e | 5054 | * to replensish the ipw->rxq->rx_free. |
43f66a6c JK |
5055 | * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the |
5056 | * ipw->rxq is replenished and the READ INDEX is updated (updating the | |
5057 | * 'processed' and 'read' driver indexes as well) | |
5058 | * + A received packet is processed and handed to the kernel network stack, | |
5059 | * detached from the ipw->rxq. The driver 'processed' index is updated. | |
5060 | * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free | |
bf79451e JG |
5061 | * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ |
5062 | * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there | |
43f66a6c JK |
5063 | * were enough free buffers and RX_STALLED is set it is cleared. |
5064 | * | |
