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 refers 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. |

* __ipw2100_tx_process |
|
* |
|
* This routine will determine whether the next packet on |
|
* the fw_pend_list has been processed by the firmware yet. |
|
* |
|
* If not, then it does nothing and returns. |
|
* |
|
* If so, then it removes the item from the fw_pend_list, frees |
|
* any associated storage, and places the item back on the |
|
* free list of its source (either msg_free_list or tx_free_list) |
|
* |
|
* TX Queue works as follows: |
|
* |
|
* Read index - points to the next TBD that the firmware will |
|
* process. The firmware will read the data, and once |
|
* done processing, it will advance the Read index. |
|
* |
|
* Write index - driver fills this entry with an constructed TBD |
|
* entry. The Write index is not advanced until the |
|
* packet has been configured. |
|
* |
|
* In between the W and R indexes are the TBDs that have NOT been |
|
* processed. Lagging behind the R index are packets that have |
|
* been processed but have not been freed by the driver. |
|
* |
|
* In order to free old storage, an internal index will be maintained |
|
* that points to the next packet to be freed. When all used |
|
* packets have been freed, the oldest index will be the same as the |
|
* firmware's read index. |
|
* |
|
* The OLDEST index is cached in the variable 'priv->tx_queue.oldest' |
|
* |
|
* Because the TBD structure can not contain arbitrary data, the |
|
* driver must keep an internal queue of cached allocations such that |
|
* it can put that data back into the tx_free_list and msg_free_list |
|
* for use by future command and data packets. |
