38 | /* | ||
39 | * Rx theory of operation | ||
40 | * | ||
41 | * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs), | ||
42 | * each of which point to Receive Buffers to be filled by the NIC. These get | ||
43 | * used not only for Rx frames, but for any command response or notification | ||
44 | * from the NIC. The driver and NIC manage the Rx buffers by means | ||
45 | * of indexes into the circular buffer. | ||
46 | * | ||
47 | * Rx Queue Indexes | ||
48 | * The host/firmware share two index registers for managing the Rx buffers. | ||
49 | * | ||
50 | * The READ index maps to the first position that the firmware may be writing | ||
51 | * to -- the driver can read up to (but not including) this position and get | ||
52 | * good data. | ||
53 | * The READ index is managed by the firmware once the card is enabled. | ||
54 | * | ||
55 | * The WRITE index maps to the last position the driver has read from -- the | ||
56 | * position preceding WRITE is the last slot the firmware can place a packet. | ||
57 | * | ||
58 | * The queue is empty (no good data) if WRITE = READ - 1, and is full if | ||
59 | * WRITE = READ. | ||
60 | * | ||
61 | * During initialization, the host sets up the READ queue position to the first | ||
62 | * INDEX position, and WRITE to the last (READ - 1 wrapped) | ||
63 | * | ||
64 | * When the firmware places a packet in a buffer, it will advance the READ index | ||
65 | * and fire the RX interrupt. The driver can then query the READ index and | ||
66 | * process as many packets as possible, moving the WRITE index forward as it | ||
67 | * resets the Rx queue buffers with new memory. | ||
68 | * | ||
69 | * The management in the driver is as follows: | ||
70 | * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free. When | ||
71 | * iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled | ||
72 | * to replenish the iwl->rxq->rx_free. | ||
73 | * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the | ||
74 | * iwl->rxq is replenished and the READ INDEX is updated (updating the | ||
75 | * 'processed' and 'read' driver indexes as well) | ||
76 | * + A received packet is processed and handed to the kernel network stack, | ||
77 | * detached from the iwl->rxq. The driver 'processed' index is updated. | ||
78 | * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free | ||
79 | * list. If there are no allocated buffers in iwl->rxq->rx_free, the READ | ||
80 | * INDEX is not incremented and iwl->status(RX_STALLED) is set. If there | ||
81 | * were enough free buffers and RX_STALLED is set it is cleared. | ||
82 | * | ||
83 | * | ||
84 | * Driver sequence: | ||
85 | * | ||
86 | * iwl_rx_queue_alloc() Allocates rx_free | ||
87 | * iwl_rx_replenish() Replenishes rx_free list from rx_used, and calls | ||
88 | * iwl_rx_queue_restock | ||
89 | * iwl_rx_queue_restock() Moves available buffers from rx_free into Rx | ||
90 | * queue, updates firmware pointers, and updates | ||
91 | * the WRITE index. If insufficient rx_free buffers | ||
92 | * are available, schedules iwl_rx_replenish | ||
93 | * | ||
94 | * -- enable interrupts -- | ||
95 | * ISR - iwl_rx() Detach iwl_rx_mem_buffers from pool up to the | ||
96 | * READ INDEX, detaching the SKB from the pool. | ||
97 | * Moves the packet buffer from queue to rx_used. | ||
98 | * Calls iwl_rx_queue_restock to refill any empty | ||
99 | * slots. | ||

3283 | /* | ||
3284 | * Rx theory of operation | ||
3285 | * | ||
3286 | * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs), | ||
3287 | * each of which point to Receive Buffers to be filled by 4965. These get | ||
3288 | * used not only for Rx frames, but for any command response or notification | ||
3289 | * from the 4965. The driver and 4965 manage the Rx buffers by means | ||
3290 | * of indexes into the circular buffer. | ||
3291 | * | ||
3292 | * Rx Queue Indexes | ||
3293 | * The host/firmware share two index registers for managing the Rx buffers. | ||
3294 | * | ||
3295 | * The READ index maps to the first position that the firmware may be writing | ||
3296 | * to -- the driver can read up to (but not including) this position and get | ||
3297 | * good data. | ||
3298 | * The READ index is managed by the firmware once the card is enabled. | ||
3299 | * | ||
3300 | * The WRITE index maps to the last position the driver has read from -- the | ||
3301 | * position preceding WRITE is the last slot the firmware can place a packet. | ||
3302 | * | ||
3303 | * The queue is empty (no good data) if WRITE = READ - 1, and is full if | ||
3304 | * WRITE = READ. | ||
3305 | * | ||
3306 | * During initialization, the host sets up the READ queue position to the first | ||
3307 | * INDEX position, and WRITE to the last (READ - 1 wrapped) | ||
3308 | * | ||
3309 | * When the firmware places a packet in a buffer, it will advance the READ index | ||
3310 | * and fire the RX interrupt. The driver can then query the READ index and | ||
3311 | * process as many packets as possible, moving the WRITE index forward as it | ||
3312 | * resets the Rx queue buffers with new memory. | ||
3313 | * | ||
3314 | * The management in the driver is as follows: | ||
3315 | * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free. When | ||
3316 | * iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled | ||
3317 | * to replenish the iwl->rxq->rx_free. | ||
3318 | * + In iwl4965_rx_replenish (scheduled) if 'processed' != 'read' then the | ||
3319 | * iwl->rxq is replenished and the READ INDEX is updated (updating the | ||
3320 | * 'processed' and 'read' driver indexes as well) | ||
3321 | * + A received packet is processed and handed to the kernel network stack, | ||
3322 | * detached from the iwl->rxq. The driver 'processed' index is updated. | ||
3323 | * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free | ||
3324 | * list. If there are no allocated buffers in iwl->rxq->rx_free, the READ | ||
3325 | * INDEX is not incremented and iwl->status(RX_STALLED) is set. If there | ||
3326 | * were enough free buffers and RX_STALLED is set it is cleared. | ||

3332 | * iwl4965_rx_replenish() Replenishes rx_free list from rx_used, and calls | ||
3333 | * iwl4965_rx_queue_restock | ||
3334 | * iwl4965_rx_queue_restock() Moves available buffers from rx_free into Rx | ||
