4.2.5.1
Package C0
The normal operating state for the processor. The processor remains in the normal
state when at least one of its cores is in the C0 or C1 state or when the platform has
not granted permission to the processor to go into a low power state. Individual cores
may be in lower power idle states while the package is in C0.
state when at least one of its cores is in the C0 or C1 state or when the platform has
not granted permission to the processor to go into a low power state. Individual cores
may be in lower power idle states while the package is in C0.
4.2.5.2
Package C1/C1E
No additional power reduction actions are taken in the package C1 state. However, if
the C1E sub-state is enabled, the processor automatically transitions to the lowest
supported core clock frequency, followed by a reduction in voltage. Autonomous power
reduction actions that are based on idle timers can trigger depending on the activity in
the system.
the C1E sub-state is enabled, the processor automatically transitions to the lowest
supported core clock frequency, followed by a reduction in voltage. Autonomous power
reduction actions that are based on idle timers can trigger depending on the activity in
the system.
The package enters the C1 low power state when:
• At least one core is in the C1 state
• The other cores are in a C1 or lower power state
