Kubernetes v1.32 introduces a new CPU Manager static policy option called strict-cpu-reservation.
This feature is currently in alpha and requires explicit enabling in the cluster.
The strict-cpu-reservation option allows defining explicit CPU sets for system and Kubernetes daemons, reducing impact from uncontrolled interrupts/timers.
Enabling the feature requires configuring CPUManagerPolicyAlphaOptions and setting strict-cpu-reservation to true.
