config ADIS16255
tristate "Analog Devices ADIS16250/16255"
depends on SPI && SYSFS
---help---
If you say yes here you get support for the Analog Devices
ADIS16250/16255 Low Power Gyroscope. The driver exposes
orientation and gyroscope value, as well as sample rate
to the sysfs.
This driver can also be built as a module. If so, the module
will be called adis16255.

BATMAN-ADV
----------
Batman advanced is a new approach to wireless networking which
does no longer operate on the IP basis. Unlike the batman daemon,
which exchanges information using UDP packets and sets routing
tables, batman-advanced operates on ISO/OSI Layer 2 only and uses
and routes (or better: bridges) Ethernet Frames. It emulates a
virtual network switch of all nodes participating. Therefore all
nodes appear to be link local, thus all higher operating proto-
cols won't be affected by any changes within the network. You can
run almost any protocol above batman advanced, prominent examples
are: IPv4, IPv6, DHCP, IPX.
Batman advanced was implemented as a Linux kernel driver to re-
duce the overhead to a minimum. It does not depend on any (other)
network driver, and can be used on wifi as well as ethernet lan,
vpn, etc ... (anything with ethernet-style layer 2).
CONFIGURATION
-------------
Load the batman-adv module into your kernel:
# insmod batman-adv.ko
The module is now waiting for activation. You must add some in-
terfaces on which batman can operate. After loading the module
batman advanced will scan your systems interfaces to search for
compatible interfaces. Once found, it will create subfolders in
the /sys directories of each supported interface, e.g.
# ls /sys/class/net/eth0/batman_adv/
# iface_status mesh_iface
If an interface does not have the "batman_adv" subfolder it prob-
ably is not supported. Not supported interfaces are: loopback,
non-ethernet and batman's own interfaces.
Note: After the module was loaded it will continuously watch for
new interfaces to verify the compatibility. There is no need to
reload the module if you plug your USB wifi adapter into your ma-
chine after batman advanced was initially loaded.
To activate a given interface simply write "bat0" into its
"mesh_iface" file inside the batman_adv subfolder:
# echo bat0 > /sys/class/net/eth0/batman_adv/mesh_iface
Repeat this step for all interfaces you wish to add. Now batman
starts using/broadcasting on this/these interface(s).
By reading the "iface_status" file you can check its status:
# cat /sys/class/net/eth0/batman_adv/iface_status
# active
To deactivate an interface you have to write "none" into its
"mesh_iface" file:
# echo none > /sys/class/net/eth0/batman_adv/mesh_iface
All mesh wide settings can be found in batman's own interface
folder:
# ls /sys/class/net/bat0/mesh/
# aggregated_ogms bonding orig_interval vis_mode
There is a special folder for debugging informations:
# ls /sys/kernel/debug/batman_adv/bat0/
# originators socket transtable_global transtable_local
# vis_data
Some of the files contain all sort of status information regard-
ing the mesh network. For example, you can view the table of
originators (mesh participants) with:
# cat /sys/kernel/debug/batman_adv/bat0/originators
Other files allow to change batman's behaviour to better fit your
requirements. For instance, you can check the current originator
interval (value in milliseconds which determines how often batman
sends its broadcast packets):
# cat /sys/class/net/bat0/mesh/orig_interval
# 1000
and also change its value:
# echo 3000 > /sys/class/net/bat0/mesh/orig_interval
In very mobile scenarios, you might want to adjust the originator
interval to a lower value. This will make the mesh more respon-
sive to topology changes, but will also increase the overhead.
USAGE
-----
To make use of your newly created mesh, batman advanced provides
a new interface "bat0" which you should use from this point on.
All interfaces added to batman advanced are not relevant any
longer because batman handles them for you. Basically, one "hands
over" the data by using the batman interface and batman will make
sure it reaches its destination.
The "bat0" interface can be used like any other regular inter-
face. It needs an IP address which can be either statically con-
figured or dynamically (by using DHCP or similar services):
# NodeA: ifconfig bat0 192.168.0.1
# NodeB: ifconfig bat0 192.168.0.2
# NodeB: ping 192.168.0.1
Note: In order to avoid problems remove all IP addresses previ-
ously assigned to interfaces now used by batman advanced, e.g.
# ifconfig eth0 0.0.0.0
VISUALIZATION
-------------
If you want topology visualization, at least one mesh node must
be configured as VIS-server:
# echo "server" > /sys/class/net/bat0/mesh/vis_mode
Each node is either configured as "server" or as "client" (de-
fault: "client"). Clients send their topology data to the server
next to them, and server synchronize with other servers. If there
is no server configured (default) within the mesh, no topology
information will be transmitted. With these "synchronizing
servers", there can be 1 or more vis servers sharing the same (or
at least very similar) data.
When configured as server, you can get a topology snapshot of
your mesh:
# cat /sys/kernel/debug/batman_adv/bat0/vis_data
This raw output is intended to be easily parsable and convertable
with other tools. Have a look at the batctl README if you want a
vis output in dot or json format for instance and how those out-
puts could then be visualised in an image.
The raw format consists of comma separated values per entry where
each entry is giving information about a certain source inter-
face. Each entry can/has to have the following values:
-> "mac" - mac address of an originator's source interface
(each line begins with it)
-> "TQ mac value" - src mac's link quality towards mac address
of a neighbor originator's interface which
is being used for routing
-> "HNA mac" - HNA announced by source mac
-> "PRIMARY" - this is a primary interface
-> "SEC mac" - secondary mac address of source
(requires preceding PRIMARY)
The TQ value has a range from 4 to 255 with 255 being the best.
The HNA entries are showing which hosts are connected to the mesh
via bat0 or being bridged into the mesh network. The PRIMARY/SEC
values are only applied on primary interfaces
LOGGING/DEBUGGING
-----------------
All error messages, warnings and information messages are sent to
the kernel log. Depending on your operating system distribution
this can be read in one of a number of ways. Try using the com-
mands: dmesg, logread, or looking in the files /var/log/kern.log
or /var/log/syslog. All batman-adv messages are prefixed with
"batman-adv:" So to see just these messages try
# dmesg | grep batman-adv
When investigating problems with your mesh network it is some-
times necessary to see more detail debug messages. This must be
enabled when compiling the batman-adv module. When building bat-
man-adv as part of kernel, use "make menuconfig" and enable the
option "B.A.T.M.A.N. debugging".
Those additional debug messages can be accessed using a special
file in debugfs
# cat /sys/kernel/debug/batman_adv/bat0/log
The additional debug output is by default disabled. It can be en-
abled during run time. Following log_levels are defined:
0 - All debug output disabled
1 - Enable messages related to routing / flooding / broadcasting
2 - Enable route or hna added / changed / deleted
3 - Enable all messages
The debug output can be changed at runtime using the file
/sys/class/net/bat0/mesh/log_level. e.g.
# echo 2 > /sys/class/net/bat0/mesh/log_level
will enable debug messages for when routes or HNAs change.
BATCTL
------
As batman advanced operates on layer 2 all hosts participating in
the virtual switch are completely transparent for all protocols
above layer 2. Therefore the common diagnosis tools do not work
as expected. To overcome these problems batctl was created. At
the moment the batctl contains ping, traceroute, tcpdump and
interfaces to the kernel module settings.
For more information, please see the manpage (man batctl).
batctl is available on http://www.open-mesh.org/

Contact: Marek Lindner <lindner_marek@yahoo.de>
Description:
Indicates whether the batman protocol messages of the

What: /sys/class/net/<mesh_iface>/mesh/bonding
Date: June 2010

same time (if available).
What: /sys/class/net/<mesh_iface>/mesh/fragmentation

Contact: Andreas Langer <an.langer@gmx.de>
Description:
Indicates whether the data traffic going through the

packet size exceeds the outgoing interface MTU.
What: /sys/class/net/<mesh_iface>/mesh/orig_interval
Date: May 2010
Contact: Marek Lindner <lindner_marek@yahoo.de>
Description:
Defines the interval in milliseconds in which batman
sends its protocol messages.
What: /sys/class/net/<mesh_iface>/mesh/vis_mode
Date: May 2010
Contact: Marek Lindner <lindner_marek@yahoo.de>
Description:
Each batman node only maintains information about its
own local neighborhood, therefore generating graphs
showing the topology of the entire mesh is not easily
feasible without having a central instance to collect
the local topologies from all nodes. This file allows
to activate the collecting (server) mode.

This driver is barely functional in its current state.
BIG:
- existing API is (/dev/tarang) should be replaced
Is it possible to use same API as Intel Wimax stack and
have same user level components.
- Qos and queue model is non-standard and inflexible.
Use existing TC Qos?
TODO:
- support more than one board - eliminate global variables
- remove developer debug BCM_DEBUG() macros
add a limited number of messages through netif_msg()
- fix non-standard kernel style
- sparse warnings
- checkpatch warnings
- remove compatiablity code for older kernels
- remove #ifdef's
- fix bogus device nameing and reference counting (see bcm_notify_event)
- fix use of file I/O to load config
- request firmware
- update to current network device API
- merge some files together
- use request firmware
- fix use of file I/O to load config with better API
- merge some files together?
- cleanup/eliminate debug messages
- integrate with existing Wimax stack?
