GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
||||
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Library General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, write to the author
|
||||
to ask for permission. For software which is copyrighted by the Free
|
||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||
make exceptions for this. Our decision will be guided by the two goals
|
||||
of preserving the free status of all derivatives of our free software and
|
||||
of promoting the sharing and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||
REPAIR OR CORRECTION.
|
||||
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||
POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This program is free software; you can redistribute it and/or modify
|
||||
it under the terms of the GNU General Public License as published by
|
||||
the Free Software Foundation; either version 2 of the License, or
|
||||
(at your option) any later version.
|
||||
|
||||
This program is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||||
GNU General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU General Public License
|
||||
along with this program; if not, write to the Free Software
|
||||
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||||
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program is interactive, make it output a short notice like this
|
||||
when it starts in an interactive mode:
|
||||
|
||||
Gnomovision version 69, Copyright (C) year name of author
|
||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, the commands you use may
|
||||
be called something other than `show w' and `show c'; they could even be
|
||||
mouse-clicks or menu items--whatever suits your program.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

|
||||
This General Public License does not permit incorporating your program into
|
||||
proprietary programs. If your program is a subroutine library, you may
|
||||
consider it more useful to permit linking proprietary applications with the
|
||||
library. If this is what you want to do, use the GNU Library General
|
||||
Public License instead of this License.

===============================================================================
|
||||
1: Minimal requirements:
|
||||
=======================================
|
||||
|
||||
===================
|
||||
1.1: kernel
|
||||
=========
|
||||
|
||||
- The minimal required kernel version is 2.6.22-rc1
|
||||
|
||||
- It is important that the installed kernel sources match
|
||||
the running kernel. Unless you are crosscompiling and you
|
||||
know what you are doing.
|
||||
|
||||
- Depending on what rt2x00 components will be built,
|
||||
some kernel configuration options are mandatory.
|
||||
It does however not matter if these options are compiled
|
||||
into the kernel or compiled as module.
|
||||
|
||||
Kernel config option Required for component
|
||||
------------------------------------------------------------------
|
||||
# CONFIG_NET_RADIO all
|
||||
# CONFIG_MAC80211 all
|
||||
# CONFIG_WLAN_80211 all
|
||||
# CONFIG_PCI rt2400pci, rt2500pci, rt61pci
|
||||
# CONFIG_USB rt2500usb, rt73usb
|
||||
# CONFIG_HOTPLUG rt61pci, rt73usb
|
||||
# CONFIG_FW_LOADER rt61pci, rt73usb
|
||||
# CONFIG_CRC_ITU_T rt61pci, rt73usb
|
||||
# CONFIG_DEBUG_FS rt2x00 (optional, only for debug)
|
||||
# CONFIG_RFKILL rt2400pci, rt2500pci, rt61pci (optional,
|
||||
only for button support)
|
||||
|
||||
===================
|
||||
1.2: GCC
|
||||
=========
|
||||
|
||||
- For building the rt2x00 components the same gcc version is required
|
||||
as was used to build your target kernel.
|
||||
|
||||
===================
|
||||
1.3: make
|
||||
=========
|
||||
|
||||
- The program 'make' needs to be installed on the system. There are no
|
||||
further special requirements for this program.
|
||||
|
||||
===============================================================================
|
||||
2: Hardware
|
||||
=======================================
|
||||
|
||||
===================
|
||||
2.1: Chipsets
|
||||
=========
|
||||
|
||||
Support for each Ralink wireless chipset has been split into separate drivers.
|
||||
|
||||
# rt2400pci
|
||||
- chipset: rt2400
|
||||
- supports: rt2460
|
||||
- bus type: PCI/PCMCIA/miniPCI
|
||||
# rt2500pci
|
||||
- chipset: rt2500
|
||||
- supports: rt2560
|
||||
- bus type: PCI/PCMCIA/miniPCI
|
||||
# rt2500usb
|
||||
- chipset: rt2570
|
||||
- supports: rt2570
|
||||
- bus type: USB
|
||||
# rt61pci
|
||||
- chipset: rt61 (or rt2600)
|
||||
- supports: rt2561, rt2561s, rt2661
|
||||
- bus type: PCI/PCMCIA/miniPCI
|
||||
# rt73usb
|
||||
- chipset: rt73
|
||||
- supports: rt2571(w), rt2573, rt2671
|
||||
- bus type: USB
|
||||
|
||||
===================
|
||||
2.2: RF button
|
||||
=========
|
||||
|
||||
On some occasions the Ralink chipset has been built into a laptop.
|
||||
If that is the case, there usually is a hardware button that controls the
|
||||
radio of the wireless interface.
|
||||
If you have such a hardware device, make sure you enable hardware button
|
||||
support for your device in the configuration before building the rt2x00
|
||||
components.
|
||||
Note: This feature requires the enabling of the rfkill driver in the kernel.
|
||||
|
||||
===============================================================================
|
||||
3: Module building & Installation
|
||||
=======================================
|
||||
|
||||
===================
|
||||
3.1: Introduction
|
||||
=========
|
||||
|
||||
The following steps in this chapter concerning module building and
|
||||
installation need to be performed for each kernel. This means that
|
||||
after each kernel upgrade the modules need to be rebuild and
|
||||
reinstalled in order to make them work with the new kernel.
|
||||
|
||||
===================
|
||||
3.2: Configure
|
||||
=========
|
||||
|
||||
Before starting to build the rt2x00 components it is recommended to look into
|
||||
the 'config' file first. In this file you can configure which components of
|
||||
rt2x00 should be built. And even more importantly, you can configure with
|
||||
what options the components will be built.
|
||||
To build all the rt2x00 drivers (with debug capabilities enabled) no changes
|
||||
in the configuration file are required. For most users this would be
|
||||
sufficient to start working with rt2x00.
|
||||
|
||||
===================
|
||||
3.3: Build
|
||||
=========
|
||||
|
||||
To build all rt2x00 components which were enabled in the configuration file
|
||||
simply run (root privileges not required):
|
||||
|
||||
# $ make
|
||||
|
||||
All modules (.ko files) will be created in the current directory.
|
||||
|
||||
===================
|
||||
3.4: Installation
|
||||
=========
|
||||
|
||||
All rt2x00 modules can be installed by doing (with root privileges):
|
||||
|
||||
# $ make install
|
||||
|
||||
With this command all rt2x00 modules (including rfkill and d80211) will be
|
||||
created in a newly created folder named 'rt2x00' inside the kernel modules
|
||||
directory (usually '/lib/modules/$(uname -r)/').
|
||||
|
||||
|
||||
==============================================================================
|
||||
4: Firmware
|
||||
=======================================
|
||||
|
||||
===================
|
||||
4.1: Firmware files
|
||||
=========
|
||||
|
||||
rt61pci and rt73usb require firmware to be available while loading the module.
|
||||
The following firmware files are available for each driver:
|
||||
|
||||
# rt61pci
|
||||
- rt2561.bin
|
||||
- rt2561s.bin
|
||||
- rt2661.bin
|
||||
|
||||
# rt73usb
|
||||
- rt73.bin
|
||||
|
||||
===================
|
||||
4.2: Firmware installation
|
||||
=========
|
||||
|
||||
The latest firmware files are available in a separate .zip archive and can be
|
||||
downloaded from the support page on the Ralink website at
|
||||
http://www.ralinktech.com.
|
||||
Note that by a high level of logic, Ralink has named their firmware for rt73
|
||||
chipsets "rt71W" with a comment that it is for the rt2571W and rt2671 devices.
|
||||
For rt61pci 3 seperate firmware files are available, which one is used depends
|
||||
on which RT chip is on the device. Usually it is best to install all files.
|
||||
To install the firmware the firmware files need to be manually copied to the
|
||||
systems firmware folder (usually '/lib/firmware/') the exact folder depends
|
||||
on the distribution. When in doubt consult the distributions documentation.
|
||||
|
||||
===================
|
||||
4.3: Firmware requirements
|
||||
=========
|
||||
|
||||
To load firmware when the module is loaded the hotplug daemon should be
|
||||
running. Make sure you either enable hotplugging manually before loading the
|
||||
module, or make sure hotplugging is enabled during the system boot process.
|
||||
|
||||
|
||||
==============================================================================
|
||||
5: Module loading
|
||||
=======================================
|
||||
|
||||
===================
|
||||
5.1: Module load order
|
||||
=========
|
||||
|
||||
When the modules have been properly installed by following the installation
|
||||
instructions from the previous section, the module handlers (i.e. modprobe)
|
||||
will automaticly resolve all module dependencies when loading the device
|
||||
specific driver.
|
||||
|
||||
When loading the modules manually with insmod, you should load them in the
|
||||
following order:
|
||||
|
||||
# eeprom_93cx6.ko (optional, only required for pci devices)
|
||||
# rt2x00lib.ko
|
||||
# rt2x00pci.ko (optional, only required for pci devices)
|
||||
# rt2x00usb.ko (optional, only required for usb devices)
|
||||
# rt2400pci.ko (optional, only required for rt2400 support)
|
||||
# rt2500pci.ko (optional, only required for rt2500 support)
|
||||
# rt2500usb.ko (optional, only required for rt2570 support)
|
||||
# rt61pci.ko (optional, only required for rt61 support)
|
||||
# rt73usb.ko (optional, only required for rt73 support)
|
||||
|
||||
===================
|
||||
5.2: Module load options
|
||||
=========
|
||||
|
||||
None.
|
||||
|
||||
|
||||
==============================================================================
|
||||
6: Interfaces
|
||||
=======================================
|
||||
|
||||
===================
|
||||
6.1: Wireless interfaces
|
||||
=========
|
||||
|
||||
After loading the modules two interfaces will now be visible in ifconfig and
|
||||
iwconfig, namely wmaster0 and wlan0. The first device is the so called master
|
||||
device which is can be used by some userspace tools, but normally can be
|
||||
ignored by the user. The second interface wlan0 is the client interface which
|
||||
the user can configure.
|
||||
With rt2x00 it is possible to run multiple client interfaces with
|
||||
only a single device. 1 client interface can run in adhoc, managed or master
|
||||
mode while a second interface can run in monitor mode at the same time.
|
||||
More client interfaces can be added by issuing the following command
|
||||
(with root privileges):
|
||||
|
||||
# $ echo -n <name> > /sys/class/ieee80211/<dev>/add_iface
|
||||
|
||||
where the variable <name> is the name of the client interface that should be
|
||||
added (i.e. wlan1), and <dev> is the physical device where the new client
|
||||
interface should be attached to (i.e. phy0).
|
||||
|
||||
===================
|
||||
6.2: Input interface
|
||||
=========
|
||||
|
||||
When the rfkill driver is being used a new input device with the name of the
|
||||
device specific module where the button belongs to will have been created.
|
||||
Whenever the user presses the hardware button the rfkill driver will
|
||||
automatically make sure the hardware radio is being disabled or enabled
|
||||
accordingly. When the user has opened the input device the radio will
|
||||
not be automatically controlled, but instead the input device will
|
||||
report all button events (KEY_RFKILL) to userspace where the user
|
||||
could have setup script to do all the work that has to be executed.
|
||||
This means that while the input device is opened, the user is responsible
|
||||
for the correct behaviour.
|
||||
|
||||
|
||||
==============================================================================
|
||||
7: Interface configuration
|
||||
=======================================
|
||||
|
||||
===================
|
||||
7.1: Minimal configuration
|
||||
=========
|
||||
|
||||
- After loading the modules the interface should be configured to start
|
||||
an association or work in monitor mode. The following steps are required
|
||||
for a minimal configuration to associate with a non-encrypted access point.
|
||||
|
||||
- Before bringing the client interface up, the working mode should be set:
|
||||
|
||||
# $ iwconfig wlan0 mode managed
|
||||
|
||||
- Configuration parts like essid and channel can be set before or after the
|
||||
client interface has been brought up.
|
||||
|
||||
- It is usually a good idea to set the essid:
|
||||
|
||||
# $ iwconfig wlan0 essid myessid
|
||||
|
||||
- In some situations the device also requires the channel to be manually set:
|
||||
|
||||
# $ iwconfig wlan0 channel mychannel
|
||||
|
||||
- To bring the client interface up:
|
||||
|
||||
# $ ifconfig wlan0 up
|
||||
|
||||
- After the client interface has been brought up, scanning can be performed
|
||||
to check if the desired AP is being detected.
|
||||
|
||||
# $ iwlist wlan0 scan
|
||||
|
||||
- To start an association attempt, the AP address should be set:
|
||||
|
||||
# $ iwconfig wlan0 ap mybssid
|
||||
|
||||
===================
|
||||
7.2: Configuration tools
|
||||
=========
|
||||
|
||||
To configure the interface several tools are possible, the most basic tools
|
||||
are the wireless-tools that provide the iwconfig, iwpriv and iwlist commands.
|
||||
For WPA connections the wireless-tools are not sufficient, to configure the
|
||||
interface for WPA wireless network wpa_supplicant is required.
|
||||
For master mode functionality it is possible to only use the wireless-tools,
|
||||
but it is recommended to use hostapd instead. This tool offers the best
|
||||
functionality.
|
||||
For all configuration tools (wireless-tools, wpa_supplicant and hostapd) are
|
||||
manuals and howto's present in the manpages or on the internet. It is adviced
|
||||
to have at least read the manpages before using the tools for a better
|
||||
understanding on configuring the interface.
|
||||

||||
8: Distribution specific notes
|
||||
=======================================
|
||||
|
||||
===================
|
||||
8.1: Debian & derivatives
|
||||
=========
|
||||
|
||||
In some instances installing the rt2x00 drivers on debian will result
|
||||
in the problem that the files are being copied into the wrong folder,
|
||||
which results in the fact that the driver cannot be loaded.
|
||||
Installing the drivers should be done manually in this case,
|
||||
please refer to the distributions documentation regarding the proper
|
||||
location of the kernel modules.
|
||||
|
||||
===================
|
||||
8.2: Fedora
|
||||
=========
|
||||
|
||||
Although rt2x00 contains many backward compatibility fixes to ensure
|
||||
that all rt2x00 components will be able to compile and run on all
|
||||
systems that meet the minimal requirements, this does not work in all
|
||||
situations when the Fedora kernels are being used.
|
||||
The problem lies in the fact that Fedora (like most other distributions)
|
||||
heavily patch their kernel for better stability and more features.
|
||||
Unlike the other distributions however, Fedora does not pay attention to
|
||||
compatibility for external kernel drivers. This means that compiling rt2x00
|
||||
while using a Fedora kernel will result in compile errors regarding unknown
|
||||
fields in structures or problems with function arguments.
|
||||
For rt2x00 it is impossible to make all checks to support all Fedora kernel
|
||||
releases. This means that when rt2x00 compilation is failing while using a
|
||||
Fedora kernel we cannot give support for the compilation steps.
|
||||
We recommend the user to complain to the Fedora developers when this problem
|
||||
occurs.
|
||||
If the user has managed to compile rt2x00 for a Fedora kernel we will
|
||||
give support for possible problems while working with rt2x00. So the only
|
||||
part we do not support is the building of rt2x00.
|
||||
Please note that when you have edited the rt2x00 code to make it compile,
|
||||
it is advised to state those changes in bugreports while reporting other
|
||||
problems with rt2x00.
|
||||
|
||||
===================
|
||||
8.3: Gentoo
|
||||
=========
|
||||
|
||||
rt2x00 can also be found in portage, both the beta releases and the cvs tree.
|
||||
Because rt2x00 is still experimental these ebuild are still masked, this means
|
||||
that before you can emerge them they first have to be unmasked.
|
||||
Gentoo provides various instructions on how this can be done on their website.
|
||||
|
||||
===================
|
||||
8.4: Mandriva
|
||||
=========
|
||||
|
||||
In some instances installing the rt2x00 drivers on Mandriva will result
|
||||
in the problem that the files are being copied into the wrong folder,
|
||||
which results in the fact that the driver cannot be loaded.
|
||||
Installing the drivers should be done manually in this case,
|
||||
please refer to the distributions documentation regarding the proper
|
||||
location of the kernel modules.
|
||||
|
||||

|
||||
9: Problems & Troubleshooting
|
||||
=======================================
|
||||
|
||||
===================
|
||||
9.1: Debug information
|
||||
=========
|
||||
|
||||
When reporting problems make sure the driver has been compiled with debug
|
||||
enabled.
|
||||
If you have done so, the debug output can be found in the output
|
||||
of 'dmesg' and also in /var/log/messages and /var/log/syslog.
|
||||
|
||||
===================
|
||||
9.2: Debugfs
|
||||
=========
|
||||
|
||||
rt2x00 provides several debugfs entries which can be used to help
|
||||
provide more information about the interface.
|
||||
To see the rt2x00 debugfs entries, debugfs should first be mounted,
|
||||
to do this you should issue the following command:
|
||||
|
||||
# $ mount -t debugfs none /debug
|
||||
|
||||
Where /debug is the directy on which the debugfs entries should appear,
|
||||
make sure this directory exists when mounting debugfs.
|
||||
With the debugfs folder, the rt2x00 folder with the rt2x00 debugfs entries
|
||||
will be created. Within the rt2x00 folder, each physical device will be
|
||||
represented by a folder named after the interface which belongs to this
|
||||
device. Within the folder the following files can be found:
|
||||
|
||||
# register
|
||||
- This file contains the register contents of the interface.
|
||||
# eeprom
|
||||
- This file contains the eeprom contents of the interface.
|
||||
|
||||
===================
|
||||
9.3: Bug reporting
|
||||
=========
|
||||
|
||||
When reporting a bug or problem with the rt2x00 module,
|
||||
make sure you report the following information:
|
||||
# How to reproduce
|
||||
# RT2x00 debug output, usually found in /var/log/messages
|
||||
# Module version
|
||||
# Wireless card chipset, model and manufacturer
|
||||
# Kernel version (i.e. 2.6.17)
|
||||
# Hardware architecture (i.e. x86, AMD64, Sparc)
|
||||
# rt2x00 code changes done by the user
|
||||
# Anything else you may think will help us resolve the issue
|
||||
|
||||
|
||||
==============================================================================
|
||||
10: Problems & Workarounds
|
||||
=======================================
|
||||
|
||||
===================
|
||||
10.1: udev interface naming
|
||||
=========
|
||||
|
||||
In some cases when loading the rt2x00 drivers the interface names are
|
||||
different from the names used in this README. This is usually caused by the
|
||||
udev handler who has set some rules regarding the interface. These rules
|
||||
are usually set up by the distribution and have been created especially for
|
||||
for the legacy driver and their strange behavior.
|
||||
To change the rules udev applies to your interface you should edit the udev
|
||||
rules stored in /etc/udev/rules.d/ (exact location might be different
|
||||
depending on distribution).
|
||||
When editing this file, search for the line that contains something like this:
|
||||
|
||||
# ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*",
|
||||
# SYSFS{address}=="<mac address>", NAME="<interface>"
|
||||
(line has been wrapped due to max line length limit)
|
||||
|
||||
Where <mac address> is the hardware address of your wireless networkcard,
|
||||
and <interface> is the interface name the interface takes as soon as the
|
||||
rt2x00 modules are loaded.
|
||||
This line should be changed to look like:
|
||||
|
||||
# ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*",
|
||||
# SYSFS{address}=="<mac address>", SYSFS{type}=="801",
|
||||
# NAME="wmaster0"
|
||||
# ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*",
|
||||
# SYSFS{address}=="<mac address>", NAME="wlan0"
|
||||
(the 2 lines have been wrapped due to max line length limit)
|
||||
|
||||
Where <mac address> is the hardware address of your wireless networkcard,
|
||||
and thus should be the same as on the original line.
|
||||
|
||||
===================
|
||||
10.2: BUG - ifdown & ifup radio failure
|
||||
=========
|
||||
|
||||
It is a known issue (and BUG) that the driver will fail to correctly resume
|
||||
its radio operations after the interface has been brought down and up again.
|
||||
It is still unknown what the cause for this issue could be, besides the fact
|
||||
that for some reason the device's registers have been incorrectly initialized.
|
||||
This issue also has impact on the device status after a suspend/resume
|
||||
operation. There is no known workaround for this yet.
|
||||
