4.9. RTAI-Linux (Part Two)

• Linux is "idle thread" for RTAI

• RTAI tasks are Linux kernel modules (actually below Linux) which never block

• Standard Linux drivers are therefore not real-time (e.g. networking)

• Memory corruption possible because kernel address space is used in real-time tasks

• LXRT (not yet available for PowerPC) allows user space real-time

• Split application in real-time part (kernel module) and rest (user space)
