Ok, we recently pushed the latest version of the IPW2100 driver to a
stable version. The last stable version was 1.0.0, which wasn't
compatible with the latest ieee80211 subsystem currently in netdev-2.6.
In addition to fixing to be compatible w/ the ieee80211 stack, 1.1.0
also includes quite a few fixes over what was in 1.0.0.
Anyway, attached is the patch against netdev-2.6 (build tested w/ the
tip of wireless-2.6) that adds ipw2100 1.1.0 to the tree.
Please let me know your comments and feedback.
I wasn't sure where to actually stick the driver's selection it in the
Kconfig menu. Where its at now, it doesn't show up until you enable
'Generic IEEE 80211 subsystem', and then it shows up down under Wireless
Lan entries.
Any opposition to creating a Wireless Drivers under the Generic IEEE
80211 level and putting drivers using that stack into that location?
In terms of the process used for validation on the ipw2100, our plan is
to only push patches out for kernel mainline inclusion that have gone
through internal regression testing.
Kernel API migration changes aren't much of an issue, but any
functionality changes or fixes would need to go into our development
versions on SourceForge first before we would want them pushed into
mainline (assuming we get this into netdev, and then pushed upstream...)
I'll be sending an ipw2200-1.0.0 patch out soon. We also have some
fixes for ieee80211 that have been incorporated into the latest
development snapshots for the ipw2200 project that I'll send a patch out
for.
Thanks,
James

+March 14, 2005
+
+===========================
+Index
+---------------------------
+0. Introduction
+1. Release 1.1.0 Current Features
+2. Command Line Parameters

+4. Radio Kill Switch
+5. Dynamic Firmware
+6. Power Management

+
+===========================
+0. Introduction
+------------ ----- ----- ---- --- -- -
+
+This document provides a brief overview of the features supported by the
+IPW2100 driver project. The main project website, where the latest
+development version of the driver can be found, is:
+
+ http://ipw2100.sourceforge.net
+
+There you can find the not only the latest releases, but also information about
+potential fixes and patches, as well as links to the development mailing list
+for the driver project.
+
+
+===========================
+1. Release 1.1.0 Current Supported Features
+---------------------------
+- Managed (BSS) and Ad-Hoc (IBSS)
+- WEP (shared key and open)
+- Wireless Tools support
+- 802.1x (tested with XSupplicant 1.0.1)
+
+Enabled (but not supported) features:
+- Monitor/RFMon mode
+- WPA/WPA2
+
+The distinction between officially supported and enabled is a reflection
+on the amount of validation and interoperability testing that has been
+performed on a given feature.
+
+
+===========================
+2. Command Line Parameters
+---------------------------
+
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax:
+
+ modprobe ipw2100 [<option>=<VAL1><,VAL2>...]
+
+For example, to disable the radio on driver loading, enter:
+
+ modprobe ipw2100 disable=1
+
+The ipw2100 driver supports the following module parameters:
+
+Name Value Example:
+debug 0x0-0xffffffff debug=1024
+mode 0,1,2 mode=1 /* AdHoc */
+channel int channel=3 /* Only valid in AdHoc or Monitor */
+associate boolean associate=0 /* Do NOT auto associate */
+disable boolean disable=1 /* Do not power the HW */
+
+
+===========================
+3. Sysfs Helper Files
+---------------------------
+
+There are several ways to control the behavior of the driver. Many of the
+general capabilities are exposed through the Wireless Tools (iwconfig). There
+are a few capabilities that are exposed through entries in the Linux Sysfs.
+
+
+----- Driver Level ------
+For the driver level files, look in /sys/bus/pci/drivers/ipw2100/
+
+ debug_level
+
+ This controls the same global as the 'debug' module parameter. For
+ information on the various debugging levels available, run the 'dvals'
+ script found in the driver source directory.
+
+ NOTE: 'debug_level' is only enabled if CONFIG_IPW2100_DEBUG is turn
+ on.
+
+----- Device Level ------
+For the device level files look in
+
+ /sys/bus/pci/drivers/ipw2100/{PCI-ID}/
+
+For example:
+ /sys/bus/pci/drivers/ipw2100/0000:02:01.0
+
+For the device level files, see /sys/bus/pci/drivers/ipw2100:
+
+ rf_kill
+ read -
+ 0 = RF kill not enabled (radio on)
+ 1 = SW based RF kill active (radio off)
+ 2 = HW based RF kill active (radio off)
+ 3 = Both HW and SW RF kill active (radio off)
+ write -
+ 0 = If SW based RF kill active, turn the radio back on
+ 1 = If radio is on, activate SW based RF kill
+
+ NOTE: If you enable the SW based RF kill and then toggle the HW
+ based RF kill from ON -> OFF -> ON, the radio will NOT come back on
+
+
+===========================
+4. Radio Kill Switch
+---------------------------
+Most laptops provide the ability for the user to physically disable the radio.
+Some vendors have implemented this as a physical switch that requires no
+software to turn the radio off and on. On other laptops, however, the switch
+is controlled through a button being pressed and a software driver then making
+calls to turn the radio off and on. This is referred to as a "software based
+RF kill switch"
+
+See the Sysfs helper file 'rf_kill' for determining the state of the RF switch
+on your system.
+
+
+===========================
+5. Dynamic Firmware
+---------------------------
+As the firmware is licensed under a restricted use license, it can not be
+included within the kernel sources. To enable the IPW2100 you will need a
+firmware image to load into the wireless NIC's processors.
+
+You can obtain these images from <http://ipw2100.sf.net/firmware.php>.
+
+See INSTALL for instructions on installing the firmware.
+
+
+===========================
+6. Power Management
+---------------------------
+The IPW2100 supports the configuration of the Power Save Protocol
+through a private wireless extension interface. The IPW2100 supports
+the following different modes:
+
+ off No power management. Radio is always on.
+ on Automatic power management
+ 1-5 Different levels of power management. The higher the
+ number the greater the power savings, but with an impact to
+ packet latencies.
+
+Power management works by powering down the radio after a certain
+interval of time has passed where no packets are passed through the
+radio. Once powered down, the radio remains in that state for a given
+period of time. For higher power savings, the interval between last
+packet processed to sleep is shorter and the sleep period is longer.
+
+When the radio is asleep, the access point sending data to the station
+must buffer packets at the AP until the station wakes up and requests
+any buffered packets. If you have an AP that does not correctly support
+the PSP protocol you may experience packet loss or very poor performance
+while power management is enabled. If this is the case, you will need
+to try and find a firmware update for your AP, or disable power
+management (via `iwconfig eth1 power off`)
+
+To configure the power level on the IPW2100 you use a combination of
+iwconfig and iwpriv. iwconfig is used to turn power management on, off,
+and set it to auto.
+
+ iwconfig eth1 power off Disables radio power down
+ iwconfig eth1 power on Enables radio power management to
+ last set level (defaults to AUTO)
+ iwpriv eth1 set_power 0 Sets power level to AUTO and enables
+ power management if not previously
+ enabled.
+ iwpriv eth1 set_power 1-5 Set the power level as specified,
+ enabling power management if not
+ previously enabled.
+
+You can view the current power level setting via:
+
+ iwpriv eth1 get_power
+
+It will return the current period or timeout that is configured as a string
+in the form of xxxx/yyyy (z) where xxxx is the timeout interval (amount of
+time after packet processing), yyyy is the period to sleep (amount of time to
+wait before powering the radio and querying the access point for buffered
+packets), and z is the 'power level'. If power management is turned off the
+xxxx/yyyy will be replaced with 'off' -- the level reported will be the active
+level if `iwconfig eth1 power on` is invoked.

+
+ See <file:Documentation/networking/README.ipw2100> for information on
+ the capabilities currently enabled in this driver and for tips

+
+ In order to use this driver, you will need a firmware image for it.
+ You can obtain the firmware from
+ <http://ipw2100.sf.net/>. Once you have the firmware image, you
+ will need to place it in /etc/firmware.
+
+ You will also very likely need the Wireless Tools in order to

+
+ <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
+
+ If you want to compile the driver as a module ( = code which can be

+/*
+
+ Initial driver on which this is based was developed by Janusz Gorycki,
+ Maciej Urbaniak, and Maciej Sosnowski.
+
+ Promiscuous mode support added by Jacek Wysoczynski and Maciej Urbaniak.
+
+Theory of Operation
+
+Tx - Commands and Data
+
+Firmware and host share a circular queue of Transmit Buffer Descriptors (TBDs)
+Each TBD contains a pointer to the physical (dma_addr_t) address of data being
+sent to the firmware as well as the length of the data.
+
+The host writes to the TBD queue at the WRITE index. The WRITE index points
+to the _next_ packet to be written and is advanced when after the TBD has been
+filled.
+
+The firmware pulls from the TBD queue at the READ index. The READ index points
+to the currently being read entry, and is advanced once the firmware is
+done with a packet.
+
+When data is sent to the firmware, the first TBD is used to indicate to the
+firmware if a Command or Data is being sent. If it is Command, all of the
+command information is contained within the physical address referred to by the
+TBD. If it is Data, the first TBD indicates the type of data packet, number
+of fragments, etc. The next TBD then referrs to the actual packet location.
+
+The Tx flow cycle is as follows:
+
+1) ipw2100_tx() is called by kernel with SKB to transmit
+2) Packet is move from the tx_free_list and appended to the transmit pending
+ list (tx_pend_list)
+3) work is scheduled to move pending packets into the shared circular queue.
+4) when placing packet in the circular queue, the incoming SKB is DMA mapped
+ to a physical address. That address is entered into a TBD. Two TBDs are
+ filled out. The first indicating a data packet, the second referring to the
+ actual payload data.
+5) the packet is removed from tx_pend_list and placed on the end of the
+ firmware pending list (fw_pend_list)
+6) firmware is notified that the WRITE index has
+7) Once the firmware has processed the TBD, INTA is triggered.
+8) For each Tx interrupt received from the firmware, the READ index is checked
+ to see which TBDs are done being processed.
+9) For each TBD that has been processed, the ISR pulls the oldest packet
+ from the fw_pend_list.
+10)The packet structure contained in the fw_pend_list is then used
+ to unmap the DMA address and to free the SKB originally passed to the driver
+ from the kernel.
+11)The packet structure is placed onto the tx_free_list
+
+The above steps are the same for commands, only the msg_free_list/msg_pend_list
+are used instead of tx_free_list/tx_pend_list
+
+...
+
+Critical Sections / Locking :
+
+There are two locks utilized. The first is the low level lock (priv->low_lock)
+that protects the following:
+
+- Access to the Tx/Rx queue lists via priv->low_lock. The lists are as follows:
+
+ tx_free_list : Holds pre-allocated Tx buffers.
+ TAIL modified in __ipw2100_tx_process()
+ HEAD modified in ipw2100_tx()
+
+ tx_pend_list : Holds used Tx buffers waiting to go into the TBD ring
+ TAIL modified ipw2100_tx()
+ HEAD modified by X__ipw2100_tx_send_data()
+
+ msg_free_list : Holds pre-allocated Msg (Command) buffers
+ TAIL modified in __ipw2100_tx_process()
+ HEAD modified in ipw2100_hw_send_command()
+
+ msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring
+ TAIL modified in ipw2100_hw_send_command()
+ HEAD modified in X__ipw2100_tx_send_commands()
+
+ The flow of data on the TX side is as follows:
+
+ MSG_FREE_LIST + COMMAND => MSG_PEND_LIST => TBD => MSG_FREE_LIST
+ TX_FREE_LIST + DATA => TX_PEND_LIST => TBD => TX_FREE_LIST
+
+ The methods that work on the TBD ring are protected via priv->low_lock.
+
+- The internal data state of the device itself
+- Access to the firmware read/write indexes for the BD queues
+ and associated logic
+
+All external entry functions are locked with the priv->action_lock to ensure
+that only one external action is invoked at a time.

I personally enable the driver to be selected directly and
then SELECT the 802.11 stack, the same way you SELECT the firmware
loader. The logic is that the user doesn't really care how it's
implemented under the cover (via the 802.11 stack or not), he just
want to make his hardware work. A good example of this logic is the
Aironet driver (PCI versus Pcmcia).
But, those are trivial matter that can be discussed and
resolved long after the driver is in the kernel, so no need to respin
your patch. Anyway, most people use distro kernels that have all
options enabled...
Apart from that, congratulation on the excellent work...
Have fun...
Jean

Good idea; I took that approach for the ipw2200 submission (just sent).

So when will intel release the firmware under a proper license so
driver is actually useable?
