This layer is intended to be a central point for realtime related kernel and system development. It also contains utilities, and configuration useful for tuning a realtime system. It should be useful directly on top of oe-core. It should be primarily useful to the following groups: - Anyone working on Linux kernel realtime development (preempt-rt, sched_dealine, posix realtime). - Anyone experimenting with alternative pairing of general purpose OSs and realtime OS divisions. Whether that be AMP, userspace RTOS or realtime hypervisors. - Anyone working on cpu isolation, system partitioning and related userspace applications. - Anyone benchmarking and performance profiling a Linux system.
