| |
| Initial driver on which this is based was developed by Janusz Gorycki, |
| Maciej Urbaniak, and Maciej Sosnowski. |
| |
| Promiscuous mode support added by Jacek Wysoczynski and Maciej Urbaniak. |
| |
| Theory of Operation |
| |
| Tx - Commands and Data |
| |
| Firmware and host share a circular queue of Transmit Buffer Descriptors (TBDs) |
| Each TBD contains a pointer to the physical (dma_addr_t) address of data being |
| sent to the firmware as well as the length of the data. |
| |
| The host writes to the TBD queue at the WRITE index. The WRITE index points |
| to the _next_ packet to be written and is advanced when after the TBD has been |
| filled. |
| |
| The firmware pulls from the TBD queue at the READ index. The READ index points |
| to the currently being read entry, and is advanced once the firmware is |
| done with a packet. |
| |
| When data is sent to the firmware, the first TBD is used to indicate to the |
| firmware if a Command or Data is being sent. If it is Command, all of the |
| command information is contained within the physical address referred to by the |
| TBD. If it is Data, the first TBD indicates the type of data packet, number |
| of fragments, etc. The next TBD then referrs to the actual packet location. |
| |
| The Tx flow cycle is as follows: |
| |
| 1) ipw2100_tx() is called by kernel with SKB to transmit |
| 2) Packet is move from the tx_free_list and appended to the transmit pending |
| list (tx_pend_list) |
| 3) work is scheduled to move pending packets into the shared circular queue. |
| 4) when placing packet in the circular queue, the incoming SKB is DMA mapped |
| to a physical address. That address is entered into a TBD. Two TBDs are |
| filled out. The first indicating a data packet, the second referring to the |
| actual payload data. |
| 5) the packet is removed from tx_pend_list and placed on the end of the |
| firmware pending list (fw_pend_list) |
| 6) firmware is notified that the WRITE index has |
| 7) Once the firmware has processed the TBD, INTA is triggered. |
| 8) For each Tx interrupt received from the firmware, the READ index is checked |
| to see which TBDs are done being processed. |
| 9) For each TBD that has been processed, the ISR pulls the oldest packet |
| from the fw_pend_list. |
| 10)The packet structure contained in the fw_pend_list is then used |
| to unmap the DMA address and to free the SKB originally passed to the driver |
| from the kernel. |
| 11)The packet structure is placed onto the tx_free_list |
| |
| The above steps are the same for commands, only the msg_free_list/msg_pend_list |
| are used instead of tx_free_list/tx_pend_list |
| |
| ... |
| |
| Critical Sections / Locking : |
| |
| There are two locks utilized. The first is the low level lock (priv->low_lock) |
| that protects the following: |
| |
| - Access to the Tx/Rx queue lists via priv->low_lock. The lists are as follows: |
| |
| tx_free_list : Holds pre-allocated Tx buffers. |
| TAIL modified in __ipw2100_tx_process() |
| HEAD modified in ipw2100_tx() |
| |
| tx_pend_list : Holds used Tx buffers waiting to go into the TBD ring |
| TAIL modified ipw2100_tx() |
| HEAD modified by ipw2100_tx_send_data() |
| |
| msg_free_list : Holds pre-allocated Msg (Command) buffers |
| TAIL modified in __ipw2100_tx_process() |
| HEAD modified in ipw2100_hw_send_command() |
| |
| msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring |
| TAIL modified in ipw2100_hw_send_command() |
| HEAD modified in ipw2100_tx_send_commands() |
| |
| The flow of data on the TX side is as follows: |
| |
| MSG_FREE_LIST + COMMAND => MSG_PEND_LIST => TBD => MSG_FREE_LIST |
| TX_FREE_LIST + DATA => TX_PEND_LIST => TBD => TX_FREE_LIST |
| |
| The methods that work on the TBD ring are protected via priv->low_lock. |
| |
| - The internal data state of the device itself |
| - Access to the firmware read/write indexes for the BD queues |
| and associated logic |
| |
| All external entry functions are locked with the priv->action_lock to ensure |
| that only one external action is invoked at a time. |
