Phoronix: Linux 5.8 Supporting Intel TPAUSE Power-Optimized Delays, TSC Fix When Overclocking
TPAUSE is the new Intel instruction for supporting lightweight power/performance optimized and improved power/performance states for sleeping until the timestamp counter (TSC) has reached a desired value. This new instruction with Intel's Tremont architecture will now be used by Linux 5.8+ on supported CPUs for an optimized power state while waiting on a delay event...
