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.

|
|
* 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.

|
|

|
* 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
