transmeta decided years before intel and amd that a constant rate tsc (unaffected by P-state) was the only sane choice. on transmeta cpus the tsc increments at the maximum cpu frequency no matter what the P-state (and no matter what longrun is doing behind the kernel's back). mind you, many people thought this was a crazy choice at the time... -dean - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
