When CYC packets are not available, it is still possible to count cycles using TSC/TMA/MTC timestamps. As the timestamp increments in TSC ticks, convert to CPU cycles using the current core-to-bus ratio. Do not accumulate cycles when control flow packet generation is not enabled, nor when time has been "lost", typically due to mwait, which is indicated by a TSC/TMA packet that is not part of PSB+.
