Modern processors have several power saving modes called C-states . They reflect the capability of an idle processor to turn off unused components in order to ...
A package C-state request is determined by the lowest numerical processor IA core C-state amongst all processor IA cores. A package C-state is automatically resolved by the processor depending on the processor IA core idle power states and the status of t
It is a global setting of all CPU cores depending on the value you write the allowed states are different. It is practical to use when no CPU pinning is used.
2018年5月31日 — C-states are states when the CPU has reduced or turned off selected functions. Different processors support different numbers of C-states in ...
Processor power states include are designated C0, C1, C2, C3, …Cn. The C0 power state is an active power state where the CPU executes instructions. The C1 ...
C-State C-State residencies are collected from hardware and/or the operating system (OS). For systems that collect OS C-State residencies, CPU C-states are core power states requested by the Operating System Directed Power Management (OSPM) infrastructure
