Linux multicore resource allocation and control

摘要

It is a widely held misconception that in order to fully make use of the performance available with multicore processors, virtualization in the form of a hyper-visor must be used, along with a combination of Linux and either an RTOS or a simple runtime environment. Fueling this misconception is the notion that Linux is incapable of meeting the requirements by itself, because it is some combination of too big, too slow, or not real time. Often, it is RTOS vendors who perpetuate this virtualization misconception.
