SAE J1939 is the vehicle bus recommended practice used for communication and diagnostics among vehicle components. Originating in the car and heavy-duty truck industry in the United States, it is now widely used in other parts of the world. J1939, ISO 11783 and NMEA 2000 all share the same high level protocol. SAE J1939 can be considered the replacement for the older SAE J1708 and SAE J1587 specifications.

tristate "CAN bus subsystem support"
|
|
---help---
|
|
Controller Area Network (CAN) is a slow (up to 1Mbit/s) serial
|
|
communications protocol. Development of the CAN bus started in
|
|
1983 at Robert Bosch GmbH, and the protocol was officially
|
|
released in 1986. The CAN bus was originally mainly for automotive,
|
|
but is now widely used in marine (NMEA2000), industrial, and medical
|
|
applications. More information on the CAN network protocol family
|
|
PF_CAN is contained in <Documentation/networking/can.rst>.
|
|
|
|
If you want CAN support you should say Y here and also to the
|
|
specific driver for your controller(s) below.

|
|
---help---
|
|
The raw CAN protocol option offers access to the CAN bus via
|
|
the BSD socket API. You probably want to use the raw socket in
|
|
most cases where no higher level protocol is being used. The raw
|
|
socket has several filter options e.g. ID masking / error frames.
|
|
To receive/send raw CAN messages, use AF_CAN with protocol CAN_RAW.

tristate "Broadcast Manager CAN Protocol (with content filtering)"

default y
|
|
---help---
|
|
The Broadcast Manager offers content filtering, timeout monitoring,
|
|
sending of RTR frames, and cyclic CAN messages without permanent user
|
|
interaction. The BCM can be 'programmed' via the BSD socket API and
|
|
informs you on demand e.g. only on content updates / timeouts.
|
|
You probably want to use the bcm socket in most cases where cyclic
|
|
CAN messages are used on the bus (e.g. in automotive environments).
|
|
To use the Broadcast Manager, use AF_CAN with protocol CAN_BCM.
|

tristate "CAN Gateway/Router (with netlink configuration)"
|
|
default y
|
|
---help---
|
|
The CAN Gateway/Router is used to route (and modify) CAN frames.
|
|
It is based on the PF_CAN core infrastructure for msg filtering and
|
|
msg sending and can optionally modify routed CAN frames on the fly.
|
|
CAN frames can be routed between CAN network interfaces (one hop).
|
|
They can be modified with AND/OR/XOR/SET operations as configured
|
|
by the netlink configuration interface known e.g. from iptables.
