| 41 | Initial driver on which this is based was developed by Janusz Gorycki, |
| 42 | Maciej Urbaniak, and Maciej Sosnowski. |
| 43 | |
| 44 | Promiscuous mode support added by Jacek Wysoczynski and Maciej Urbaniak. |
| 45 | |
| 46 | Theory of Operation |
| 47 | |
| 48 | Tx - Commands and Data |
| 49 | |
| 50 | Firmware and host share a circular queue of Transmit Buffer Descriptors (TBDs) |
| 51 | Each TBD contains a pointer to the physical (dma_addr_t) address of data being |
| 52 | sent to the firmware as well as the length of the data. |
| 53 | |
| 54 | The host writes to the TBD queue at the WRITE index. The WRITE index points |
| 55 | to the _next_ packet to be written and is advanced when after the TBD has been |
| 56 | filled. |
| 57 | |
| 58 | The firmware pulls from the TBD queue at the READ index. The READ index points |
| 59 | to the currently being read entry, and is advanced once the firmware is |
| 60 | done with a packet. |
| 61 | |
| 62 | When data is sent to the firmware, the first TBD is used to indicate to the |
| 63 | firmware if a Command or Data is being sent. If it is Command, all of the |
| 64 | command information is contained within the physical address referred to by the |
| 65 | TBD. If it is Data, the first TBD indicates the type of data packet, number |
| 66 | of fragments, etc. The next TBD then referrs to the actual packet location. |
| 67 | |
| 68 | The Tx flow cycle is as follows: |
| 69 | |
| 70 | 1) ipw2100_tx() is called by kernel with SKB to transmit |
| 71 | 2) Packet is move from the tx_free_list and appended to the transmit pending |
| 72 | list (tx_pend_list) |
| 73 | 3) work is scheduled to move pending packets into the shared circular queue. |
| 74 | 4) when placing packet in the circular queue, the incoming SKB is DMA mapped |
| 75 | to a physical address. That address is entered into a TBD. Two TBDs are |
| 76 | filled out. The first indicating a data packet, the second referring to the |
| 77 | actual payload data. |
| 78 | 5) the packet is removed from tx_pend_list and placed on the end of the |
| 79 | firmware pending list (fw_pend_list) |
| 80 | 6) firmware is notified that the WRITE index has |
| 81 | 7) Once the firmware has processed the TBD, INTA is triggered. |
| 82 | 8) For each Tx interrupt received from the firmware, the READ index is checked |
| 83 | to see which TBDs are done being processed. |
| 84 | 9) For each TBD that has been processed, the ISR pulls the oldest packet |
| 85 | from the fw_pend_list. |
| 86 | 10)The packet structure contained in the fw_pend_list is then used |
| 87 | to unmap the DMA address and to free the SKB originally passed to the driver |
| 88 | from the kernel. |
| 89 | 11)The packet structure is placed onto the tx_free_list |
| 90 | |
| 91 | The above steps are the same for commands, only the msg_free_list/msg_pend_list |
| 92 | are used instead of tx_free_list/tx_pend_list |
| 93 | |
| 94 | ... |
| 95 | |
| 96 | Critical Sections / Locking : |
| 97 | |
| 98 | There are two locks utilized. The first is the low level lock (priv->low_lock) |
| 99 | that protects the following: |
| 100 | |
| 101 | - Access to the Tx/Rx queue lists via priv->low_lock. The lists are as follows: |
| 102 | |
| 103 | tx_free_list : Holds pre-allocated Tx buffers. |
| 104 | TAIL modified in __ipw2100_tx_process() |
| 105 | HEAD modified in ipw2100_tx() |
| 106 | |
| 107 | tx_pend_list : Holds used Tx buffers waiting to go into the TBD ring |
| 108 | TAIL modified ipw2100_tx() |

James Ketrenos | 2c86c27 | 2005-03-23 17:32:29 -0600 | [diff] [blame] | 110 | |
| 111 | msg_free_list : Holds pre-allocated Msg (Command) buffers |
| 112 | TAIL modified in __ipw2100_tx_process() |
| 113 | HEAD modified in ipw2100_hw_send_command() |
| 114 | |
| 115 | msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring |
| 116 | TAIL modified in ipw2100_hw_send_command() |
Jiri Benc | 19f7f74 | 2005-08-25 20:02:10 -0400 | [diff] [blame] | 117 | HEAD modified in ipw2100_tx_send_commands() |
James Ketrenos | 2c86c27 | 2005-03-23 17:32:29 -0600 | [diff] [blame] | 118 | |
| 119 | The flow of data on the TX side is as follows: |
| 120 | |
| 121 | MSG_FREE_LIST + COMMAND => MSG_PEND_LIST => TBD => MSG_FREE_LIST |
| 122 | TX_FREE_LIST + DATA => TX_PEND_LIST => TBD => TX_FREE_LIST |
| 123 | |
| 124 | The methods that work on the TBD ring are protected via priv->low_lock. |
| 125 | |
| 126 | - The internal data state of the device itself |
| 127 | - Access to the firmware read/write indexes for the BD queues |
| 128 | and associated logic |
| 129 | |
| 130 | All external entry functions are locked with the priv->action_lock to ensure |
| 131 | that only one external action is invoked at a time. |

| 2600 | * |
| 2601 | * This routine will determine whether the next packet on |
| 2602 | * the fw_pend_list has been processed by the firmware yet. |
| 2603 | * |
| 2604 | * If not, then it does nothing and returns. |
| 2605 | * |
| 2606 | * If so, then it removes the item from the fw_pend_list, frees |
| 2607 | * any associated storage, and places the item back on the |
| 2608 | * free list of its source (either msg_free_list or tx_free_list) |
| 2609 | * |
| 2610 | * TX Queue works as follows: |
| 2611 | * |
| 2612 | * Read index - points to the next TBD that the firmware will |
| 2613 | * process. The firmware will read the data, and once |
| 2614 | * done processing, it will advance the Read index. |
| 2615 | * |
| 2616 | * Write index - driver fills this entry with an constructed TBD |
| 2617 | * entry. The Write index is not advanced until the |
| 2618 | * packet has been configured. |
| 2619 | * |
| 2620 | * In between the W and R indexes are the TBDs that have NOT been |
| 2621 | * processed. Lagging behind the R index are packets that have |
| 2622 | * been processed but have not been freed by the driver. |
| 2623 | * |
| 2624 | * In order to free old storage, an internal index will be maintained |
| 2625 | * that points to the next packet to be freed. When all used |
| 2626 | * packets have been freed, the oldest index will be the same as the |
| 2627 | * firmware's read index. |
| 2628 | * |
| 2629 | * The OLDEST index is cached in the variable 'priv->tx_queue.oldest' |
| 2630 | * |
| 2631 | * Because the TBD structure can not contain arbitrary data, the |
| 2632 | * driver must keep an internal queue of cached allocations such that |
| 2633 | * it can put that data back into the tx_free_list and msg_free_list |
| 2634 | * for use by future command and data packets. |
