Intel C1 Demotion Knob Proposed For The Linux Kernel To Help Newer Xeon CPUs
A patch has been proposed for the Linux kernel to add a C1 demotion knob via /sys/devices/system/cpu/cpuidle/c1_demotion for more control over lower power state handling for recent Xeon Scalable processors
A patch has been proposed for the Linux kernel to add a C1 demotion knob via/sys/devices/system/cpu/cpuidle/c1_demotion for more control over lower power state handling for recent Xeon Scalable processors. This C1 demotion knob can help with the performance of some workloads for Intel Xeon servers but at the cost of increased power consumption. Will be interesting to benchmark this C1 demotion patch when ready for quantifying the performance and power impact.About The AuthorMichael Larabel is the principal author of Phoronix.com and founded the site in 2004 with a focus on enriching the Linux hardware experience.
