4914 | * Rx theory of operation |
4915 | * | |
4916 | * The host allocates 32 DMA target addresses and passes the host address | |
b095c381 | 4917 | * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is |
43f66a6c JK |
4918 | * 0 to 31 |
4919 | * | |
4920 | * Rx Queue Indexes | |
4921 | * The host/firmware share two index registers for managing the Rx buffers. | |
4922 | * | |
bf79451e JG |
4923 | * The READ index maps to the first position that the firmware may be writing |
4924 | * to -- the driver can read up to (but not including) this position and get | |
4925 | * good data. | |
43f66a6c JK |
4926 | * The READ index is managed by the firmware once the card is enabled. |
4927 | * | |
4928 | * The WRITE index maps to the last position the driver has read from -- the | |
4929 | * position preceding WRITE is the last slot the firmware can place a packet. | |
4930 | * | |
4931 | * The queue is empty (no good data) if WRITE = READ - 1, and is full if | |
bf79451e | 4932 | * WRITE = READ. |
43f66a6c | 4933 | * |
bf79451e | 4934 | * During initialization the host sets up the READ queue position to the first |
43f66a6c JK |
4935 | * INDEX position, and WRITE to the last (READ - 1 wrapped) |
4936 | * | |
4937 | * When the firmware places a packet in a buffer it will advance the READ index | |
4938 | * and fire the RX interrupt. The driver can then query the READ index and | |
4939 | * process as many packets as possible, moving the WRITE index forward as it | |
4940 | * resets the Rx queue buffers with new memory. | |
bf79451e | 4941 | * |
43f66a6c | 4942 | * The management in the driver is as follows: |
bf79451e | 4943 | * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When |
43f66a6c | 4944 | * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled |
bf79451e | 4945 | * to replensish the ipw->rxq->rx_free. |
43f66a6c JK |
4946 | * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the |
4947 | * ipw->rxq is replenished and the READ INDEX is updated (updating the | |
4948 | * 'processed' and 'read' driver indexes as well) | |
4949 | * + A received packet is processed and handed to the kernel network stack, | |
4950 | * detached from the ipw->rxq. The driver 'processed' index is updated. | |
4951 | * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free | |
bf79451e JG |
4952 | * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ |
4953 | * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there | |
43f66a6c JK |
4954 | * were enough free buffers and RX_STALLED is set it is cleared. |
4955 | * | |
4956 | * | |
4957 | * Driver sequence: | |
4958 | * | |
bf79451e | 4959 | * ipw_rx_queue_alloc() Allocates rx_free |
43f66a6c JK |
4960 | * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls |
4961 | * ipw_rx_queue_restock | |
4962 | * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx | |
4963 | * queue, updates firmware pointers, and updates | |
4964 | * the WRITE index. If insufficient rx_free buffers | |
4965 | * are available, schedules ipw_rx_queue_replenish | |
4966 | * | |
4967 | * -- enable interrupts -- | |
4968 | * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the | |
