In response to a recent and very lengthy thread , Paul E. McKenney provided an interesting summary of the current attempts to patch the Linux kernel for use as a realtime operating system. His paper begins, " common wisdom dictates that realtime operating systems, particularly hard-realtime operating systems, must be designed from ground up; that serious realtime support cannot be simply grafted onto an existing general-purpose operating system. Although this common wisdom was not arrived at lightly, it is often worthwhile to look for important exceptions to this sort of general rule of thumb. " Two such exceptions that he mentions are realtime applications that use a subset of an existing operating system, and the fact that computer performance has increased so dramatically over the past few decades. Paul's paper goes on to acknowledge that there are limits that one can expect when trying to use a general-purpose OS to provide realtime services, then noting: "Nevertheless, it is clear that Linux can support significant realtime requirements, as it is already being used heavily in the realtime arena. But how far should Linux extend its realtime support, and what is the best way to extend Linux in this direction? Can one approach to realtime satisfy all reasonable requirements, or would it be better to support multiple approaches, each with its area of applicability?"
