    linux RT patch


    Hi Everyone

    I've played a little bit with Linux 2 years ago (not too much) so I know some of the terms but I'm still a newbie...
    2 years ago I've worked with a kernel version which supported the RT patch and I heard that there was some process of merging the RT patch into the kernel.

    So I have few questions regarding the RT patch:
    1) Does the RT patch still exist or it has all merged into the kernel?
    2) Is there a site that publishes the RT patch and some information about it (change log etc.)?
    3) Where can I find which kernel version supports the RT patch?

    Thanks a lot
    Tal

    The answers to your questions are as under

    1) Linux Kernel itself is not a Real Time Operating System.
    2) Inorder to port real time capabilities, patches exist. One common patch is Xenomai patch. The details of this can be obtained at Xenomai.
    3) You can see the documentation of the patch. It will provide the information of the linux kernel version it supports.
