Arch Linux based CachyOS has released their "July 2024" release that also introduces an AMD Zen 4 optimized repository that caters to current Ryzen 7000/8000 and EPYC 4004/8004/9004 (Zen 4) procssors and upcoming Zen 5 processors.

The Zen 4 optimized repository will automatically be enabled at install-time when encountering AMD Zen 4 and Zen 5 processors. The Zen 4 optimized repository makes use of the " [1]znver4 " compiler target for enabling all of the extra AVX-512 instructions and other CPU instructions on top of the base x86-64-v4 target like RDPID, RDRND, RDSEED, GFNI, and others.

CachyOS has already provided optimized repositories for various x86-64 micro-architecture feature levels while given the popularity of AMD Zen 4 processors from mobile and desktop to server, it's great seeing them provide znver4 tuned binaries now too.

CachyOS with their kernel now also patches in AMD [3]Core Performance Boost support. That AMD P-State driver support for [4]CPB is being upstreamed in Linux 6.11 while for now it's being carried by the CachyOS kernel as extra patches.

Some other recent CachyOS updates include adding a GUI to manage the sched-ext scheduler within their Kernel Manager, user-space kernel same-page merging has been dropped, updated Calamares installer, and preparing to rollout the Linux 6.10 kernel.
