Linux gets real (-time)

Anonymous Reader writes “According to an article at LinuxDevices.com, Metrowerks Senior Software Engineer and veteran real-time programmer Bernhard Kuhn has created a Linux kernel patch that enables hard, real-time performance in the Linux kernel by adding priorities to interrupts and spinlocks. Kuhn believes his approach to be more “natural” and akin to traditional real-time operating systems (RTOSs) than the dual-kernel approach taken by real-time Linux projects such as RTAI and RTLinux, and he is hopeful that his patch might one day win enough interest and support to become part of the official Linux kernel tree.”
