    Subjectperfctr-2.7.2 released
    Version 2.7.2 of perfctr, the Linux performance
    monitoring counters driver, is now available at the usual

    This version changes the user/kernel interface from ioctl()s
    to syscalls. Requested by Andrew Morton (2.6-mm kernel maintainer).

    This breaks compatibility with perfctr-2.6 user-space code,
    so don't even think about using this except for testing.
    It also only works in the 2.6.6 and 2.6.6-mm2 kernels.

    The new user-space syscall() wrappers only work with certain
    gcc versions and gcc options: x86 without -fPIC and ppc
    with gcc-3.2 work, while x86 with -fPIC, x86_64, and ppc
    with gcc-3.4.0 don't. This will be fixed in the next release.

    Version 2.7.2, 2004-05-14
    - Changes for submission to 2.6.6-mm kernel. Replaced
    ioctl() interface by new syscall (by request, not choice).
    Eliminated module support and backwards compatibility.
    Many other cleanups.
