help
|
RT-Socket-CAN is a real-time socket interface for CAN controllers.

config XENO_DRIVERS_CAN_DEBUG
|
depends on XENO_DRIVERS_CAN && PROC_FS
|
bool "Enable debug output"
|
default y
|
help
|
|
This option activates debugging checks and enhanced output for the
|
RT-Socket-CAN driver. It also allows to list the hardware registers
|
of the registered CAN controllers. It is a recommended option for
|
getting started and analysing potential problems. For production
|
purposes, it should be switched off (for the sake of latency).

|
config XENO_DRIVERS_CAN_LOOPBACK
|
depends on XENO_DRIVERS_CAN
|
bool "Enable TX loopback to local sockets"
|
default n
|
help
|
|
This options adds support for TX loopback to local sockets. Normally,
|
messages sent to the CAN bus are not visible to sockets listening to
|
the same local device. When this option is enabled, TX messages are
|
looped back locally when the transmit has been done by default. This
|
behaviour can be deactivated or reactivated with "setsockopt". Enable
|
this option, if you want to have a "net-alike" behaviour.

int "Maximum number of receive filters per device"

help
|

The driver maintains a receive filter list per device for fast access.

config XENO_DRIVERS_CAN_BUS_ERR

depends on XENO_DRIVERS_CAN

bool
|
default n
|
help
|
|
To avoid unnecessary bus error interrupt flooding, this option enables
|
bus error interrupts when an application is calling a receive function
|
on a socket listening on bus errors. After one bus error has occured,
|
the interrupt will be disabled to allow the application time for error
|
processing. This option is automatically selected for CAN controllers
|
supporting bus error interrupts like the SJA1000.
|
|
config XENO_DRIVERS_CAN_CALC_BITTIME_OLD
|
depends on XENO_DRIVERS_CAN
|
bool "Old bit-time calculation algorithm (deprecated)"
|
default n
|
help
|
|
This option allows to enable the old algorithm to calculate the
|
CAN bit-timing parameters for backward compatibility.

tristate "Virtual CAN bus driver"
|
help
|
|
This driver provides two CAN ports that are virtually interconnected.
|
More ports can be enabled with the module parameter "devices".

Say Y here if you want to support for Freescale FlexCAN.
