145 A driver for the Intel PRO/Wireless 2100 Network
146 Connection 802.11b wireless network adapter.
147
148 See <file:Documentation/networking/README.ipw2100> for information on
149 the capabilities currently enabled in this driver and for tips
150 for debugging issues and problems.
151
152 In order to use this driver, you will need a firmware image for it.
153 You can obtain the firmware from
154 <http://ipw2100.sf.net/>. Once you have the firmware image, you
155 will need to place it in /etc/firmware.
156
157 You will also very likely need the Wireless Tools in order to
158 configure your card:
159
160 <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
161
162 If you want to compile the driver as a module ( = code which can be
163 inserted in and remvoed from the running kernel whenever you want),
164 say M here and read <file:Documentation/modules.txt>. The module
165 will be called ipw2100.ko.

171 Enables promiscuous/monitor mode support for the ipw2100 driver.
172 With this feature compiled into the driver, you can switch to
173 promiscuous mode via the Wireless Tool's Monitor mode. While in this
174 mode, no packets can be sent.

178 depends on IPW2100
179 ---help---
180 This option will enable debug tracing output for the IPW2100.
181
182 This will result in the kernel module being ~60k larger. You can
183 control which debug output is sent to the kernel log by setting the
184 value in
185
186 /sys/bus/pci/drivers/ipw2100/debug_level
187
188 This entry will only exist if this option is enabled.

4 ---help---
5 Shared driver code for IEEE 802.11b wireless cards based on
6 Intersil Prism2/2.5/3 chipset. This driver supports so called
7 Host AP mode that allows the card to act as an IEEE 802.11
8 access point.
9
10 See <http://hostap.epitest.fi/> for more information about the
11 Host AP driver configuration and tools. This site includes
12 information and tools (hostapd and wpa_supplicant) for WPA/WPA2
13 support.
14
15 This option includes the base Host AP driver code that is shared by
16 different hardware models. You will also need to enable support for
17 PLX/PCI/CS version of the driver to actually use the driver.
18
19 The driver can be compiled as a module and it will be called
20 "hostap.ko".

13 *
14 * FIX:
15 * - there is currently no way of associating TX packets to correct wds device
16 * when TX Exc/OK event occurs, so all tx_packets and some
17 * tx_errors/tx_dropped are added to the main netdevice; using sw_support
18 * field in txdesc might be used to fix this (using Alloc event to increment
19 * tx_packets would need some further info in txfid table)
20 *
21 * Buffer Access Path (BAP) usage:
22 * Prism2 cards have two separate BAPs for accessing the card memory. These
23 * should allow concurrent access to two different frames and the driver
24 * previously used BAP0 for sending data and BAP1 for receiving data.
25 * However, there seems to be number of issues with concurrent access and at
26 * least one know hardware bug in using BAP0 and BAP1 concurrently with PCI
27 * Prism2.5. Therefore, the driver now only uses BAP0 for moving data between
28 * host and card memories. BAP0 accesses are protected with local->baplock
29 * (spin_lock_bh) to prevent concurrent use.

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.

2663 *
2664 * The OLDEST index is cached in the variable 'priv->tx_queue.oldest'
2665 *
2666 * Because the TBD structure can not contain arbitrary data, the

2621 * A queue is a circular buffers with 'Read' and 'Write' pointers.
2622 * 2 empty entries always kept in the buffer to protect from overflow.
2623 *
2624 * For Tx queue, there are low mark and high mark limits. If, after queuing
2625 * the packet for Tx, free space become < low mark, Tx queue stopped. When
2626 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
2627 * Tx queue resumed.
2628 *
2629 * The IPW operates with six queues, one receive queue in the device's
2630 * sram, one transmit queue for sending commands to the device firmware,
2631 * and four transmit queues for data.
2632 *
2633 * The four transmit queues allow for performing quality of service (qos)
2634 * transmissions as per the 802.11 protocol. Currently Linux does not
2635 * provide a mechanism to the user for utilizing prioritized queues, so
2636 * we only utilize the first data transmit queue (queue1).

3801 * Rx theory of operation
3802 *
3803 * The host allocates 32 DMA target addresses and passes the host address
3804 * to the firmware at register CX2_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
3805 * 0 to 31
3806 *
3807 * Rx Queue Indexes
3808 * The host/firmware share two index registers for managing the Rx buffers.
3809 *
3810 * The READ index maps to the first position that the firmware may be writing
3811 * to -- the driver can read up to (but not including) this position and get
3812 * good data.
3813 * The READ index is managed by the firmware once the card is enabled.
3814 *
3815 * The WRITE index maps to the last position the driver has read from -- the
3816 * position preceding WRITE is the last slot the firmware can place a packet.
3817 *
3818 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
3819 * WRITE = READ.
3820 *
3821 * During initialization the host sets up the READ queue position to the first
3822 * INDEX position, and WRITE to the last (READ - 1 wrapped)
3823 *
3824 * When the firmware places a packet in a buffer it will advance the READ index
3825 * and fire the RX interrupt. The driver can then query the READ index and
3826 * process as many packets as possible, moving the WRITE index forward as it
3827 * resets the Rx queue buffers with new memory.
3828 *
3829 * The management in the driver is as follows:
3830 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
3831 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
3832 * to replensish the ipw->rxq->rx_free.
3833 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
3834 * ipw->rxq is replenished and the READ INDEX is updated (updating the
3835 * 'processed' and 'read' driver indexes as well)
3836 * + A received packet is processed and handed to the kernel network stack,
3837 * detached from the ipw->rxq. The driver 'processed' index is updated.
3838 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
3839 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
3840 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
3841 * were enough free buffers and RX_STALLED is set it is cleared.
3842 *
3843 *
3844 * Driver sequence:
3845 *
3846 * ipw_rx_queue_alloc() Allocates rx_free
3847 * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
3848 * ipw_rx_queue_restock
3849 * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
3850 * queue, updates firmware pointers, and updates
3851 * the WRITE index. If insufficient rx_free buffers
3852 * are available, schedules ipw_rx_queue_replenish
3853 *
3854 * -- enable interrupts --
3855 * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the
3856 * READ INDEX, detaching the SKB from the pool.
3857 * Moves the packet buffer from queue to rx_used.
3858 * Calls ipw_rx_queue_restock to refill any empty
3859 * slots.
