13 A driver for the Intel PRO/Wireless 2100 Network
14 Connection 802.11b wireless network adapter.
15
16 See <file:Documentation/networking/README.ipw2100> for information on
17 the capabilities currently enabled in this driver and for tips
18 for debugging issues and problems.
19
20 In order to use this driver, you will need a firmware image for it.
21 You can obtain the firmware from
22 <http://ipw2100.sf.net/>. Once you have the firmware image, you
23 will need to place it in /lib/firmware.
24
25 You will also very likely need the Wireless Tools in order to
26 configure your card:
27
28 <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
29
30 It is recommended that you compile this driver as a module (M)
31 rather than built-in (Y). This driver requires firmware at device
32 initialization time, and when built-in this typically happens
33 before the filesystem is accessible (hence firmware will be
34 unavailable and initialization will fail). If you do choose to build
35 this driver into your kernel image, you can avoid this problem by
36 including the firmware and a firmware loader in an initramfs.
37
38config IPW2100_MONITOR
39 bool "Enable promiscuous mode"
40 depends on IPW2100
41 ---help---
42 Enables promiscuous/monitor mode support for the ipw2100 driver.
43 With this feature compiled into the driver, you can switch to
44 promiscuous mode via the Wireless Tool's Monitor mode. While in this
45 mode, no packets can be sent.
46
47config IPW2100_DEBUG
48 bool "Enable full debugging output in IPW2100 module."
49 depends on IPW2100
50 ---help---
51 This option will enable debug tracing output for the IPW2100.
52
53 This will result in the kernel module being ~60k larger. You can
54 control which debug output is sent to the kernel log by setting the
55 value in
56
57 /sys/bus/pci/drivers/ipw2100/debug_level
58
59 This entry will only exist if this option is enabled.
60
61 If you are not trying to debug or develop the IPW2100 driver, you
62 most likely want to say N here.

101 Enables promiscuous/monitor mode support for the ipw2200 driver.

113 select IPW2200_RADIOTAP
114 ---help---
115 Enables the creation of a second interface prefixed 'rtap'.
116 This second interface will provide every received in radiotap
117 format.
118
119 This is useful for performing wireless network analysis while
120 maintaining an active association.
121
122 Example usage:
123
124 % modprobe ipw2200 rtap_iface=1
125 % ifconfig rtap0 up
126 % tethereal -i rtap0
127
128 If you do not specify 'rtap_iface=1' as a module parameter then
129 the rtap interface will not be created and you will need to turn
130 it on via sysfs:
131
132 % echo 1 > /sys/bus/pci/drivers/ipw2200/*/rtap_iface
133
134config IPW2200_QOS

137
138config IPW2200_DEBUG
139 bool "Enable full debugging output in IPW2200 module."
140 depends on IPW2200
141 ---help---
142 This option will enable low level debug tracing output for IPW2200.
143
144 Note, normal debug code is already compiled in. This low level
145 debug option enables debug on hot paths (e.g Tx, Rx, ISR) and
146 will result in the kernel module being ~70 larger. Most users
147 will typically not need this high verbosity debug information.
148
149 If you are not sure, say N here.

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()
109 HEAD modified by ipw2100_tx_send_data()
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()
117 HEAD modified in ipw2100_tx_send_commands()
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.

3590 *
3591 * A queue is a circular buffers with 'Read' and 'Write' pointers.
3592 * 2 empty entries always kept in the buffer to protect from overflow.
3593 *
3594 * For Tx queue, there are low mark and high mark limits. If, after queuing
3595 * the packet for Tx, free space become < low mark, Tx queue stopped. When
3596 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
3597 * Tx queue resumed.
3598 *
3599 * The IPW operates with six queues, one receive queue in the device's
3600 * sram, one transmit queue for sending commands to the device firmware,
3601 * and four transmit queues for data.
3602 *
3603 * The four transmit queues allow for performing quality of service (qos)
3604 * transmissions as per the 802.11 protocol. Currently Linux does not
3605 * provide a mechanism to the user for utilizing prioritized queues, so
3606 * we only utilize the first data transmit queue (queue1).

5010 * Rx theory of operation
5011 *
5012 * The host allocates 32 DMA target addresses and passes the host address
5013 * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
5014 * 0 to 31
5015 *
5016 * Rx Queue Indexes
5017 * The host/firmware share two index registers for managing the Rx buffers.
5018 *
5019 * The READ index maps to the first position that the firmware may be writing
5020 * to -- the driver can read up to (but not including) this position and get
5021 * good data.
5022 * The READ index is managed by the firmware once the card is enabled.
5023 *
5024 * The WRITE index maps to the last position the driver has read from -- the
5025 * position preceding WRITE is the last slot the firmware can place a packet.
5026 *
5027 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
5028 * WRITE = READ.
5029 *
5030 * During initialization the host sets up the READ queue position to the first
5031 * INDEX position, and WRITE to the last (READ - 1 wrapped)
5032 *
5033 * When the firmware places a packet in a buffer it will advance the READ index
5034 * and fire the RX interrupt. The driver can then query the READ index and
5035 * process as many packets as possible, moving the WRITE index forward as it
5036 * resets the Rx queue buffers with new memory.
5037 *
5038 * The management in the driver is as follows:
5039 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
5040 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
5041 * to replensish the ipw->rxq->rx_free.
5042 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
5043 * ipw->rxq is replenished and the READ INDEX is updated (updating the
5044 * 'processed' and 'read' driver indexes as well)
5045 * + A received packet is processed and handed to the kernel network stack,
5046 * detached from the ipw->rxq. The driver 'processed' index is updated.
5047 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
5048 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
5049 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
5050 * were enough free buffers and RX_STALLED is set it is cleared.
5051 *
5052 *
5053 * Driver sequence:
5054 *
5055 * ipw_rx_queue_alloc() Allocates rx_free
5056 * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
5057 * ipw_rx_queue_restock
5058 * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
5059 * queue, updates firmware pointers, and updates
5060 * the WRITE index. If insufficient rx_free buffers
5061 * are available, schedules ipw_rx_queue_replenish
5062 *
5063 * -- enable interrupts --
5064 * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the
5065 * READ INDEX, detaching the SKB from the pool.
5066 * Moves the packet buffer from queue to rx_used.
5067 * Calls ipw_rx_queue_restock to refill any empty
5068 * slots.
