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 | ||
46 | Theory of Operation | |
47 | ||
48 | Tx - Commands and Data | |
49 | ||
50 | Firmware and host share a circular queue of Transmit Buffer Descriptors (TBDs) | |
51 | Each TBD contains a pointer to the physical (dma_addr_t) address of data being | |
52 | sent to the firmware as well as the length of the data. | |
53 | ||
54 | The host writes to the TBD queue at the WRITE index. The WRITE index points | |
55 | to the _next_ packet to be written and is advanced when after the TBD has been | |
56 | filled. | |
57 | ||
58 | The firmware pulls from the TBD queue at the READ index. The READ index points | |
59 | to the currently being read entry, and is advanced once the firmware is | |
60 | done with a packet. | |
61 | ||
62 | When data is sent to the firmware, the first TBD is used to indicate to the | |
63 | firmware if a Command or Data is being sent. If it is Command, all of the | |
64 | command information is contained within the physical address referred to by the | |
65 | TBD. If it is Data, the first TBD indicates the type of data packet, number | |
66 | of fragments, etc. The next TBD then referrs to the actual packet location. | |
67 | ||
68 | The Tx flow cycle is as follows: | |
69 | ||
70 | 1) ipw2100_tx() is called by kernel with SKB to transmit | |
71 | 2) Packet is move from the tx_free_list and appended to the transmit pending | |
72 | list (tx_pend_list) | |
73 | 3) work is scheduled to move pending packets into the shared circular queue. | |
74 | 4) 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. | |
78 | 5) the packet is removed from tx_pend_list and placed on the end of the | |
79 | firmware pending list (fw_pend_list) | |
80 | 6) firmware is notified that the WRITE index has | |
81 | 7) Once the firmware has processed the TBD, INTA is triggered. | |
82 | 8) For each Tx interrupt received from the firmware, the READ index is checked | |
83 | to see which TBDs are done being processed. | |
84 | 9) For each TBD that has been processed, the ISR pulls the oldest packet | |
85 | from the fw_pend_list. | |
86 | 10)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. | |
89 | 11)The packet structure is placed onto the tx_free_list | |
90 | ||
91 | The above steps are the same for commands, only the msg_free_list/msg_pend_list | |
92 | are used instead of tx_free_list/tx_pend_list | |
93 | ||
94 | ... | |
95 | ||
96 | Critical Sections / Locking : | |
97 | ||
98 | There are two locks utilized. The first is the low level lock (priv->low_lock) | |
99 | that 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 | ||
130 | All external entry functions are locked with the priv->action_lock to ensure | |
131 | that only one external action is invoked at a time. | |
