27 Initial driver on which this is based was developed by Janusz Gorycki,
28 Maciej Urbaniak, and Maciej Sosnowski.
30 Promiscuous mode support added by Jacek Wysoczynski and Maciej Urbaniak.
34 Tx - Commands and Data
36 Firmware and host share a circular queue of Transmit Buffer Descriptors (TBDs)
37 Each TBD contains a pointer to the physical (dma_addr_t) address of data being
38 sent to the firmware as well as the length of the data.
40 The host writes to the TBD queue at the WRITE index. The WRITE index points
41 to the _next_ packet to be written and is advanced when after the TBD has been
44 The firmware pulls from the TBD queue at the READ index. The READ index points
45 to the currently being read entry, and is advanced once the firmware is
48 When data is sent to the firmware, the first TBD is used to indicate to the
49 firmware if a Command or Data is being sent. If it is Command, all of the
50 command information is contained within the physical address referred to by the
51 TBD. If it is Data, the first TBD indicates the type of data packet, number
52 of fragments, etc. The next TBD then refers to the actual packet location.
54 The Tx flow cycle is as follows:
56 1) ipw2100_tx() is called by kernel with SKB to transmit
57 2) Packet is move from the tx_free_list and appended to the transmit pending
59 3) work is scheduled to move pending packets into the shared circular queue.
60 4) 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
64 5) the packet is removed from tx_pend_list and placed on the end of the
65 firmware pending list (fw_pend_list)
66 6) firmware is notified that the WRITE index has
67 7) Once the firmware has processed the TBD, INTA is triggered.
68 8) For each Tx interrupt received from the firmware, the READ index is checked
69 to see which TBDs are done being processed.
70 9) For each TBD that has been processed, the ISR pulls the oldest packet
71 from the fw_pend_list.
72 10)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
75 11)The packet structure is placed onto the tx_free_list
77 The above steps are the same for commands, only the msg_free_list/msg_pend_list
78 are used instead of tx_free_list/tx_pend_list
82 Critical Sections / Locking :
84 There are two locks utilized. The first is the low level lock (priv->low_lock)
85 that protects the following:
87 - Access to the Tx/Rx queue lists via priv->low_lock. The lists are as follows:
89 tx_free_list : Holds pre-allocated Tx buffers.
90 TAIL modified in __ipw2100_tx_process()
91 HEAD modified in ipw2100_tx()
93 tx_pend_list : Holds used Tx buffers waiting to go into the TBD ring
94 TAIL modified ipw2100_tx()
95 HEAD modified by ipw2100_tx_send_data()
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()
101 msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring
102 TAIL modified in ipw2100_hw_send_command()
103 HEAD modified in ipw2100_tx_send_commands()
105 The flow of data on the TX side is as follows:
107 MSG_FREE_LIST + COMMAND => MSG_PEND_LIST => TBD => MSG_FREE_LIST
108 TX_FREE_LIST + DATA => TX_PEND_LIST => TBD => TX_FREE_LIST
110 The methods that work on the TBD ring are protected via priv->low_lock.
112 - The internal data state of the device itself
113 - Access to the firmware read/write indexes for the BD queues
116 All external entry functions are locked with the priv->action_lock to ensure
117 that only one external action is invoked at a time.
