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 “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 Core Performance Boost support. That AMD P-State driver support for 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.
