Some thoughts on hardware that is used for real-time workload. Certainly not complete but should cover some of the import topics such as: - Main memory, caches and the possiblie control given by the hardware. - What could happen by putting critical hardware behind USB or VirtIO. - Allowing real-time tasks to consume the CPU entirely without giving the system some time to breath. - Networking with what the kernel provides.

interested in the inner workings of PREEMPT_RT. It explains key concepts and
|
|
the required changes compared to a non-PREEMPT_RT configuration.
