About this tag
The thermal interrupts tag on WindowsForum.com covers discussions about how operating systems, particularly Linux, handle thermal events from Intel processors. Recent content highlights the Directed Package-Level Thermal Interrupts feature in Linux 7.3, which directs package-wide thermal interrupts to a single CPU instead of waking all cores. This change aims to improve power efficiency, reduce contention, and minimize disruption to idle cores on Intel systems, including laptops and high-core-count desktops or servers. The tag is relevant for users interested in thermal management, kernel behavior, and performance optimization on Intel hardware.

    Linux 7.3 Directs Intel Thermal Interrupts to One CPU

    Intel’s planned Directed Package-Level Thermal Interrupts support for Linux 7.3 is a small kernel change with unusually broad implications for power efficiency, responsiveness, and multicore scalability on compatible Intel systems. Rather than waking every online CPU in a physical processor...
