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."

    I have been waiting for this for a long time. I was not even sure whether Linus will ever accept it one day. This is a major achievement for Linux and open a lot of new opportunities in Desktop and Real time applications.

    The preemptive kernel if it is as good as it seems can only bring benefits to the linux community.

    Here is a comment by one of the MontaVista people addressing this very issue: http://www.linuxdevices.com/articles/AT5152980814. html

    Thought this might be interesting.

    Lack of eloquence does not denote lack of intelligence, though they often coincide.

    This has been applied to the development (2.5) tree not the stable (2.4) tree.
