About Red Hat Enterprise Linux for Real Time Kernel
The Red Hat Enterprise Linux for Real Time Kernel is designed to enable fine-tuning for systems with extremely high determinism requirements. The major increase in the consistency of results can, and should, be achieved by tuning the standard kernel. The real-time kernel enables gaining a small increase on top of increase achieved by tuning the standard kernel.
can-dev module has been enabled for the real-time kernel
can-dev module has been enabled for the real-time kernel, providing the device interface for Controller Area Network (CAN) device drivers. CAN is a vehicle bus specification originally intended to connect the various micro-controllers in automobiles and has since extended to other areas. CAN is also used in industrial and machine controls where a high performance interface is required and other interfaces such as RS-485 are not sufficient.
The functions exported from the
can-dev module are used by CAN device drivers to make the kernel aware of the devices and to allow applications to connect and transfer data.
Enabling CAN in the real-time kernel allows the use of third party CAN drivers and applications to implement CAN-based systems. (BZ#1328607
