-no_force_psb This is a driver option and is not in the IA32_RTIT_CTL MSR.
- It stops the driver resetting the byte count to zero whenever
- enabling the trace (for example on context switches) which in
- turn results in no PSB being forced. However some processors
- will produce a PSB anyway.
- In any case, there is still a PSB when the trace is enabled for
- the first time.
- no_force_psb can be used to slightly decrease the trace size but
- may make it harder for the decoder to recover from errors.
- no_force_psb is not selected by default.
