Preemptible Kernel Patch Accepted

Posted by michael on from the a-little-Love-for-everyone dept.

An Anonymous Coward writes: "The preemptible Linux kernel patch that was originally introduced by MontaVista Software and more recently championed by Robert Love has been merged by Linus Torvalds into the main linux development-kernel tree, beginning version v2.5.4-pre6. This adds a far greater degree of real-time responsiveness to the standard Linux kernel, by reducing interrupt latencies while kernel functions are executing. The story at LinuxDevices.com includes comments by Robert Love, and there is also a recent interview with Robert Love about the preemptable kernel here and a whitepaper about the technology by MontaVista here."

    The tradeoff is that porn on Linux will be downloaded 1% slower.

    Just so we're sure. Is that "free as in beer" or "free as in free speech"?

    Wow. Welcome to 1973. What's it like back there, caveman? Are you "grooving" to those "funky" "disco beats"?

    Yes. It all sucks. As has been said in the past though, there is a certain range of problems for which *nix sucks twice as fast and ten times more reliably than Windows.

    Quake 3 has never been smoother on my machine. 2.4.18-pre7 with Robert Love's Pre-emptible Kernel patch and Ingo's O(1) patch.

    Sounds awesome. Quick question: does Ingo's patch make all of userland O(1), or just the kernel? I'm curious.
