AMD appears to be working on a new patch 'CPU Temperature Driver' patch for Zen 4 & most likely, Mendocino APUs, to completely ready it in the main Linux kernel upon launch.

Several open-source updates for graphics card technology have appeared, but very little work has appeared for the company's current and upcoming processor structure. One recently updated issue was temperature monitoring for the CPU regarding the company's "k10temp" driver. So few updates have appeared in the past for CPUs due to initializing enough mandatory updates and code to access the full features of the processor and then fixing or patching issues as they arise promptly. And the changes are usually seen by members of the open-source community.
