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
46Theory of Operation
47
48Tx - Commands and Data
49
50Firmware and host share a circular queue of Transmit Buffer Descriptors (TBDs)
51Each TBD contains a pointer to the physical (dma_addr_t) address of data being
52sent to the firmware as well as the length of the data.
53
54The host writes to the TBD queue at the WRITE index. The WRITE index points
55to the _next_ packet to be written and is advanced when after the TBD has been
56filled.
57
58The firmware pulls from the TBD queue at the READ index. The READ index points
59to the currently being read entry, and is advanced once the firmware is
60done with a packet.
61
62When data is sent to the firmware, the first TBD is used to indicate to the
63firmware if a Command or Data is being sent. If it is Command, all of the
64command information is contained within the physical address referred to by the
65TBD. If it is Data, the first TBD indicates the type of data packet, number
66of fragments, etc. The next TBD then referrs to the actual packet location.
67
68The Tx flow cycle is as follows:
69
701) ipw2100_tx() is called by kernel with SKB to transmit
712) Packet is move from the tx_free_list and appended to the transmit pending
72 list (tx_pend_list)
733) work is scheduled to move pending packets into the shared circular queue.
744) 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.
785) the packet is removed from tx_pend_list and placed on the end of the
79 firmware pending list (fw_pend_list)
806) firmware is notified that the WRITE index has
817) Once the firmware has processed the TBD, INTA is triggered.
828) For each Tx interrupt received from the firmware, the READ index is checked
83 to see which TBDs are done being processed.
849) For each TBD that has been processed, the ISR pulls the oldest packet
85 from the fw_pend_list.
8610)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.
8911)The packet structure is placed onto the tx_free_list
90
91The above steps are the same for commands, only the msg_free_list/msg_pend_list
92are used instead of tx_free_list/tx_pend_list
93
94...
95
96Critical Sections / Locking :
97
98There are two locks utilized. The first is the low level lock (priv->low_lock)
99that 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()
19f7f742 109 HEAD modified by ipw2100_tx_send_data()
2c86c275
JK		 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()
19f7f742 117 HEAD modified in ipw2100_tx_send_commands()
2c86c275
JK		 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
130All external entry functions are locked with the priv->action_lock to ensure
131that only one external action is invoked at a time.
