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.

A New Kernel Patch Is Being Discussed That's Needed For Newer Windows Games On Wine

Newer Windows games/applications are making use of system call instructions from the application code without resorting to the WinAPI and that is breaking Wine emulation support. A Linux kernel patch is now being worked on for addressing this issue in the form of system call isolation based on memory areas while having a smaller performance hit than alternatives.
