5119 | * The READ index is managed by the firmware once the card is enabled. |
5120 | * | |
5121 | * The WRITE index maps to the last position the driver has read from -- the | |
5122 | * position preceding WRITE is the last slot the firmware can place a packet. | |
5123 | * | |
5124 | * The queue is empty (no good data) if WRITE = READ - 1, and is full if | |
bf79451e | 5125 | * WRITE = READ. |
43f66a6c | 5126 | * |
bf79451e | 5127 | * During initialization the host sets up the READ queue position to the first |
43f66a6c JK |
5128 | * INDEX position, and WRITE to the last (READ - 1 wrapped) |
5129 | * | |
5130 | * When the firmware places a packet in a buffer it will advance the READ index | |
5131 | * and fire the RX interrupt. The driver can then query the READ index and | |
5132 | * process as many packets as possible, moving the WRITE index forward as it | |
5133 | * resets the Rx queue buffers with new memory. | |
bf79451e | 5134 | * |
43f66a6c | 5135 | * The management in the driver is as follows: |
bf79451e | 5136 | * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When |
43f66a6c | 5137 | * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled |
bf79451e | 5138 | * to replensish the ipw->rxq->rx_free. |
43f66a6c JK |
5139 | * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the |
5140 | * ipw->rxq is replenished and the READ INDEX is updated (updating the | |
5141 | * 'processed' and 'read' driver indexes as well) | |
5142 | * + A received packet is processed and handed to the kernel network stack, | |
5143 | * detached from the ipw->rxq. The driver 'processed' index is updated. | |
5144 | * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free | |
bf79451e JG |
5145 | * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ |
5146 | * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there | |
43f66a6c JK |
5147 | * were enough free buffers and RX_STALLED is set it is cleared. |
5148 | * | |
5149 | * | |

5151 | * | |
bf79451e | 5152 | * ipw_rx_queue_alloc() Allocates rx_free |
43f66a6c JK |
5153 | * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls |
5154 | * ipw_rx_queue_restock | |
5155 | * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx | |
