    SubjectAMD X2 unsynced TSC fix?
    From
    Date
    Someone recently pointed out to me that a Windows "CPU driver update"
    supplied by AMD fixes the unsynced TSC problem on dual core AMD64
    systems.

    http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_871_13118,00.html

    "The AMD Dual-Core Optimizer can help improve some PC gaming video
    performance by compensating for those applications that bypass the
    Windows API for timing by directly using the RDTSC (Read Time Stamp
    Counter) instruction. Applications that rely on RDTSC do not benefit
    from the logic in the operating system to properly account for the
    affect of power management mechanisms on the rate at which a processor
    core's Time Stamp Counter (TSC) is incremented. The AMD Dual-Core
    Optimizer helps to correct the resulting video performance effects or
    other incorrect timing effects that these applications may experience on
    dual-core processor systems, by periodically adjusting the core
    time-stamp-counters, so that they are synchronized."

    What are the chances of Linux getting a similar fix?
