Auto Processor Jitter Control mode
Auto Processor Jitter Control mode
When Processor Jitter Control is configured to run in auto mode, HPE server firmware disables the impact of power management and
dynamically adjusts the processor during runtime to eliminate frequency shift induced jitter. The result of running in auto-tuned mode
is that the processor will eventually run at the highest frequency that can be achieved where the processor stops making frequency
changes to stay within its thermal, power, and core usage constraints. Auto-tuned mode lowers the frequency upon detection of
frequency changes caused by the following sources:
C-state transitions
AVX induced transitions
Turbo transitions (due to power, thermal, and core usage)
Thermal throttling
Jitter control equally affects all cores on all processors.
