27 Initial driver on which this is based was developed by Janusz Gorycki,
28 Maciej Urbaniak, and Maciej Sosnowski.
29
30 Promiscuous mode support added by Jacek Wysoczynski and Maciej Urbaniak.
31
32Theory of Operation
33
34Tx - Commands and Data
35
36Firmware and host share a circular queue of Transmit Buffer Descriptors (TBDs)
37Each TBD contains a pointer to the physical (dma_addr_t) address of data being
38sent to the firmware as well as the length of the data.
39
40The host writes to the TBD queue at the WRITE index. The WRITE index points
41to the _next_ packet to be written and is advanced when after the TBD has been
42filled.
43
44The firmware pulls from the TBD queue at the READ index. The READ index points
45to the currently being read entry, and is advanced once the firmware is
46done with a packet.
47
48When data is sent to the firmware, the first TBD is used to indicate to the
49firmware if a Command or Data is being sent. If it is Command, all of the
50command information is contained within the physical address referred to by the
51TBD. If it is Data, the first TBD indicates the type of data packet, number
Lucas De Marchi25985ed2011-03-30 22:57:33 -030052of fragments, etc. The next TBD then refers to the actual packet location.
James Ketrenos2c86c272005-03-23 17:32:29 -060053
54The Tx flow cycle is as follows:
55
561) ipw2100_tx() is called by kernel with SKB to transmit
572) Packet is move from the tx_free_list and appended to the transmit pending
58 list (tx_pend_list)
593) work is scheduled to move pending packets into the shared circular queue.
604) when placing packet in the circular queue, the incoming SKB is DMA mapped
61 to a physical address. That address is entered into a TBD. Two TBDs are
62 filled out. The first indicating a data packet, the second referring to the
63 actual payload data.
645) the packet is removed from tx_pend_list and placed on the end of the
65 firmware pending list (fw_pend_list)
666) firmware is notified that the WRITE index has
677) Once the firmware has processed the TBD, INTA is triggered.
688) For each Tx interrupt received from the firmware, the READ index is checked
69 to see which TBDs are done being processed.
709) For each TBD that has been processed, the ISR pulls the oldest packet
71 from the fw_pend_list.
7210)The packet structure contained in the fw_pend_list is then used
73 to unmap the DMA address and to free the SKB originally passed to the driver
74 from the kernel.
7511)The packet structure is placed onto the tx_free_list
76
77The above steps are the same for commands, only the msg_free_list/msg_pend_list
78are used instead of tx_free_list/tx_pend_list
79
80...
81
82Critical Sections / Locking :
83
84There are two locks utilized. The first is the low level lock (priv->low_lock)
85that protects the following:
86
87- Access to the Tx/Rx queue lists via priv->low_lock. The lists are as follows:
88
89 tx_free_list : Holds pre-allocated Tx buffers.
90 TAIL modified in __ipw2100_tx_process()
91 HEAD modified in ipw2100_tx()
92
93 tx_pend_list : Holds used Tx buffers waiting to go into the TBD ring
94 TAIL modified ipw2100_tx()
Jiri Benc19f7f742005-08-25 20:02:10 -040095 HEAD modified by ipw2100_tx_send_data()
James Ketrenos2c86c272005-03-23 17:32:29 -060096
97 msg_free_list : Holds pre-allocated Msg (Command) buffers
98 TAIL modified in __ipw2100_tx_process()
99 HEAD modified in ipw2100_hw_send_command()
100
101 msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring
102 TAIL modified in ipw2100_hw_send_command()
Jiri Benc19f7f742005-08-25 20:02:10 -0400103 HEAD modified in ipw2100_tx_send_commands()
James Ketrenos2c86c272005-03-23 17:32:29 -0600104
105 The flow of data on the TX side is as follows:
106
107 MSG_FREE_LIST + COMMAND => MSG_PEND_LIST => TBD => MSG_FREE_LIST
108 TX_FREE_LIST + DATA => TX_PEND_LIST => TBD => TX_FREE_LIST
109
110 The methods that work on the TBD ring are protected via priv->low_lock.
111
112- The internal data state of the device itself
113- Access to the firmware read/write indexes for the BD queues
114 and associated logic
115
116All external entry functions are locked with the priv->action_lock to ensure
117that only one external action is invoked at a time.
