    摘要: In an embodiment, a processor includes a plurality of cores. Each core includes a core power unit to detect one or more power management events, and in response to the one or more power management events, initiate a protected power management mode in the core. Software interrupts to the core may be disabled during the protected power management mode. The core is to execute power management code during the protected power management mode. Other embodiments are described and claimed.
