teletext adapters)
It currently supports the following devices:
- * Philips adapter
- * home brew teletext adapter
- * Velleman K8000 adapter
- * ELV adapter
- * Analog Devices evaluation boards (ADM1025, ADM1030, ADM1031, ADM1032)
+ * (type=0) Philips adapter
+ * (type=1) home brew teletext adapter
+ * (type=2) Velleman K8000 adapter
+ * (type=3) ELV adapter
+ * (type=4) Analog Devices ADM1032 evaluation board
+ * (type=5) Analog Devices evaluation boards: ADM1025, ADM1030, ADM1031
+ * (type=6) Barco LPT->DVI (K5800236) adapter
These devices use different pinout configurations, so you have to tell
the driver what you have, using the type module parameter. There is no
way to autodetect the devices. Support for different pinout configurations
can be easily added when needed.
+Earlier kernels defaulted to type=0 (Philips). But now, if the type
+parameter is missing, the driver will simply fail to initialize.

+Except for the oldest chips (VT82C596A/B, VT82C686A and most probably
+VT8231), this driver supports I2C block transactions. Such transactions
+are mainly useful to read from and write to EEPROMs.

+-----------------------------------------------
+
+Important Notice FOR ALL USERS OR DISTRIBUTORS!!!!
+
+Intel wireless LAN adapters are engineered, manufactured, tested, and
+quality checked to ensure that they meet all necessary local and
+governmental regulatory agency requirements for the regions that they
+are designated and/or marked to ship into. Since wireless LANs are
+generally unlicensed devices that share spectrum with radars,
+satellites, and other licensed and unlicensed devices, it is sometimes
+necessary to dynamically detect, avoid, and limit usage to avoid
+interference with these devices. In many instances Intel is required to
+provide test data to prove regional and local compliance to regional and
+governmental regulations before certification or approval to use the
+product is granted. Intel's wireless LAN's EEPROM, firmware, and
+software driver are designed to carefully control parameters that affect
+radio operation and to ensure electromagnetic compliance (EMC). These
+parameters include, without limitation, RF power, spectrum usage,
+channel scanning, and human exposure.
+
+For these reasons Intel cannot permit any manipulation by third parties
+of the software provided in binary format with the wireless WLAN
+adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
+patches, utilities, or code with the Intel wireless LAN adapters that
+have been manipulated by an unauthorized party (i.e., patches,
+utilities, or code (including open source code modifications) which have
+not been validated by Intel), (i) you will be solely responsible for
+ensuring the regulatory compliance of the products, (ii) Intel will bear
+no liability, under any theory of liability for any issues associated
+with the modified products, including without limitation, claims under
+the warranty and/or issues arising from regulatory non-compliance, and
+(iii) Intel will not provide or be required to assist in providing
+support to any third parties for such modified products.
+
+Note: Many regulatory agencies consider Wireless LAN adapters to be
+modules, and accordingly, condition system-level regulatory approval
+upon receipt and review of test data documenting that the antennas and
+system configuration do not cause the EMC and radio operation to be
+non-compliant.
+
+The drivers available for download from SourceForge are provided as a
+part of a development project. Conformance to local regulatory
+requirements is the responsibility of the individual developer. As
+such, if you are interested in deploying or shipping a driver as part of
+solution intended to be used for purposes other than development, please
+obtain a tested driver from Intel Customer Support at:
+
+http://support.intel.com/support/notebook/sb/CS-006408.htm
+
+
+1. 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.
+
+

+
+Enabled (but not supported) features:
- Monitor/RFMon mode
-- transmit power control
-- long/short preamble support
-- power states support (ACPI)
+- WPA/WPA2
-TODO
------------- ----- ----- ---- --- -- -
-- Fix bugs... The biggies:
- C3 corruption
- Fragmentation
+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.
-Command Line Parameters
------------- ----- ----- ---- --- -- -
+3. 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
modprobe ipw2100 [<option>=<VAL1><,VAL2>...]
-For example, to set the interface name for driver, entering:
-
- modprobe ipw2100 if_name=wlan%d
+For example, to disable the radio on driver loading, enter:
-results in the ipw2100 driver defaulting to the wlan prefix, with the system
-assigning a unique number in place of %d. The default interface name is eth%d.
+ modprobe ipw2100 disable=1
The ipw2100 driver supports the following module parameters:
Name Value Example:
debug 0x0-0xffffffff debug=1024
-if_name string if_name=wlan%d
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 */
-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"
+4. 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.
-To determine if you have such a switch, you can check the contents of:
- /sys/bus/pci/drivers/ipw2100/*/rf_kill
+----- 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.
-A value of:
+----- Device Level ------
+For the device level files look in
- Radio is {en,dis}abled by RF switch
+ /sys/bus/pci/drivers/ipw2100/{PCI-ID}/
-means that you have an RF switch and the radio is in the state
-described.
+For example:
+ /sys/bus/pci/drivers/ipw2100/0000:02:01.0
-A value of:
+For the device level files, see /sys/bus/pci/drivers/ipw2100:
- Your hardware does not have an RF switch
+ 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
-is self explanatory. In this case you should not need to worry about
-enabling the radio.
+ 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
-Dynamic Firmware
------------- ----- ----- ---- --- -- -
+5. 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.
+
+
+6. 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.
See INSTALL for instructions on installing the firmware.
-Power Management
------------- ----- ----- ---- --- -- -
+7. 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:
level if `iwconfig eth1 power on` is invoked.

At this time, a generic EEH recovery mechanism has been implemented,
so that individual device drivers do not need to be modified to support
EEH recovery. This generic mechanism piggy-backs on the PCI hotplug
-infrastructure, and percolates events up through the hotplug/udev
+infrastructure, and percolates events up through the userspace/udev
infrastructure. Followiing is a detailed description of how this is
accomplished.
EEH must be enabled in the PHB's very early during the boot process,
and if a PCI slot is hot-plugged. The former is performed by
-eeh_init() in arch/ppc64/kernel/eeh.c, and the later by
+eeh_init() in arch/powerpc/platforms/pseries/eeh.c, and the later by
drivers/pci/hotplug/pSeries_pci.c calling in to the eeh.c code.
EEH must be enabled before a PCI scan of the device can proceed.
Current Power5 hardware will not work unless EEH is enabled;
pci_get_device_by_addr() will find the pci device associated
with that address (if any).
-The default include/asm-ppc64/io.h macros readb(), inb(), insb(),
-etc. include a check to see if the the i/o read returned all-0xff's.
+The default include/asm-powerpc/io.h macros readb(), inb(), insb(),
+etc. include a check to see if the i/o read returned all-0xff's.
If so, these make a call to eeh_dn_check_failure(), which in turn
asks the firmware if the all-ff's value is the sign of a true EEH
error. If it is not, processing continues as normal. The grand
all of these occur during boot, when the PCI bus is scanned, where
a large number of 0xff reads are part of the bus scan procedure.
-If a frozen slot is detected, code in arch/ppc64/kernel/eeh.c will
-print a stack trace to syslog (/var/log/messages). This stack trace
-has proven to be very useful to device-driver authors for finding
-out at what point the EEH error was detected, as the error itself
-usually occurs slightly beforehand.

Next, it uses the Linux kernel notifier chain/work queue mechanism to
allow any interested parties to find out about the failure. Device
drivers/pci/hotplug/pSeries_pci.c, called handle_eeh_events().
It saves the device BAR's and then calls rpaphp_unconfig_pci_adapter().
This last call causes the device driver for the card to be stopped,
-which causes hotplug events to go out to user space. This triggers
+which causes uevents to go out to user space. This triggers
user-space scripts that might issue commands such as "ifdown eth0"
for ethernet cards, and so on. This handler then sleeps for 5 seconds,
hoping to give the user-space scripts enough time to complete.

+ * Read/write a 16 bit word from flash address 'addr'.
+ *
+ * When the cpu is in little-endian mode it swizzles the address lines
+ * ('address coherency') so we need to undo the swizzling to ensure commands
+ * and the like end up on the correct flash address.
+ *
+ * To further complicate matters, due to the way the expansion bus controller
+ * handles 32 bit reads, the byte stream ABCD is stored on the flash as:
+ * D15 D0
+ * +---+---+
+ * | A | B | 0
+ * +---+---+
+ * | C | D | 2
+ * +---+---+
+ * This means that on LE systems each 16 bit word must be swapped. Note that

+ * data and other flash commands which are always in D7-D0.

- * If we detect a special mapping then it doesn't have a 'struct page'.
- * We force !pfn_valid() by returning an out-of-range pointer.
- *

- * there is no PFN such that p2m(PFN) == MFN. Otherwise we can get confused if
- * we are foreign-mapping the MFN, and the other domain as m2p(MFN) == PFN.
- * Yikes! Various places must poke in INVALID_P2M_ENTRY for safety.
- *
- * NB2. When deliberately mapping foreign pages into the p2m table, you *must*
- * use FOREIGN_FRAME(). This will cause pte_pfn() to choke on it, as we
- * require. In all the cases we care about, the FOREIGN_FRAME bit is
