|
|
* Theory of operation
|
|
*
|
|
* A queue is a circular buffers with 'Read' and 'Write' pointers.
|
|
* 2 empty entries always kept in the buffer to protect from overflow.
|
|
*
|
|
* For Tx queue, there are low mark and high mark limits. If, after queuing
|
|
* the packet for Tx, free space become < low mark, Tx queue stopped. When
|
|
* reclaiming packets (on 'tx done IRQ), if free space become > high mark,
|
|
* Tx queue resumed.
|
|
*
|
|
* The IPW operates with six queues, one receive queue in the device's
|
|
* sram, one transmit queue for sending commands to the device firmware,
|
|
* and four transmit queues for data.
|
|
*
|
|
* The four transmit queues allow for performing quality of service (qos)
|
|
* transmissions as per the 802.11 protocol. Currently Linux does not
|
|
* provide a mechanism to the user for utilizing prioritized queues, so
|
|
* we only utilize the first data transmit queue (queue1).

/*
|
|
* Rx theory of operation
|
|
*
|
|
* The host allocates 32 DMA target addresses and passes the host address
|
|
* to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
|
|
* 0 to 31
|
|
*
|
|
* Rx Queue Indexes
|
|
* The host/firmware share two index registers for managing the Rx buffers.
|
|
*
|
|
* The READ index maps to the first position that the firmware may be writing
|
|
* to -- the driver can read up to (but not including) this position and get
|
|
* good data.
|
|
* The READ index is managed by the firmware once the card is enabled.
|
|
*
|
|
* The WRITE index maps to the last position the driver has read from -- the
|
|
* position preceding WRITE is the last slot the firmware can place a packet.
|
|
*
|
|
* The queue is empty (no good data) if WRITE = READ - 1, and is full if
|
|
* WRITE = READ.
|
|
*
|
|
* During initialization the host sets up the READ queue position to the first
|
|
* INDEX position, and WRITE to the last (READ - 1 wrapped)
|
|
*
|
|
* When the firmware places a packet in a buffer it will advance the READ index
|
|
* and fire the RX interrupt. The driver can then query the READ index and
|
|
* process as many packets as possible, moving the WRITE index forward as it
|
|
* resets the Rx queue buffers with new memory.
|
|
*
|
|
* The management in the driver is as follows:
|
|
* + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
|
|
* ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
|
|
* to replensish the ipw->rxq->rx_free.
|
|
* + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
|
|
* ipw->rxq is replenished and the READ INDEX is updated (updating the
|
|
* 'processed' and 'read' driver indexes as well)
|
|
* + A received packet is processed and handed to the kernel network stack,
|
|
* detached from the ipw->rxq. The driver 'processed' index is updated.
|
|
* + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
|
|
* list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
|
|
* INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
|
|
* were enough free buffers and RX_STALLED is set it is cleared.
|
|
*
|
|
*
|
|
* Driver sequence:
|
|
*
|
|
* ipw_rx_queue_alloc() Allocates rx_free
|
|
* ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
|
|
* ipw_rx_queue_restock
|
|
* ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
|
|
* queue, updates firmware pointers, and updates
|
|
* the WRITE index. If insufficient rx_free buffers
|
|
* are available, schedules ipw_rx_queue_replenish
|
|
*
|
|
* -- enable interrupts --
|
|
* ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the
|
|
* READ INDEX, detaching the SKB from the pool.
|
|
* Moves the packet buffer from queue to rx_used.
|
|
* Calls ipw_rx_queue_restock to refill any empty
|
|
* slots.
|
|
* ...
|
|
*

|
|
* If there are slots in the RX queue that need to be restocked,
|
|
* and we have free pre-allocated buffers, fill the ranks as much
|
|
* as we can pulling from rx_free.
|
|
*
|
|
* This moves the 'write' index forward to catch up with 'processed', and
