In today's article I am looking at the performance and power efficiency impact of AMD EPYC 9005 series processors with AMD's BIOS tuning recommendations for Java workloads on Linux.

It's not too often that "fixes" to the Kernel-based Virtual Machine (KVM) are noteworthy but today is an interesting exception with among the KVM fixes sent in today ahead of the Linux 6.13-rc3 tagging is for beginning to deal with a "hilarious/revolting" performance regression affecting recent generations of Intel processors. This performance regression won't be fully worked around until Linux 6.14 but at least there is an interim step in place once the code is merged later today...

Earlier this month as part of patches for cleaning up x86 32-bit kernel code for x86_64 systems, there was a patch to drop support for 32-bit x86 KVM host support. That patch has now been split off into its own patch series with also now raising the prospects of ending 32-bit KVM host support across all CPU architectures rather than being just an x86-only change...

With the in-development Linux 6.13 kernel one of the biggest features for those using new AMD EPYC 9005 "Turin" processors is using the AMD P-State driver by default for servers/motherboards with ACPI CPPC support enabled. But even for platforms without that where ACPI CPUFreq remains the default, the Linux 6.13 kernel is still showing some nice incremental uplift at large on these new AMD server processors. Here are some Linux 6.11 vs. 6.12 vs. 6.13 Git kernel benchmarks using an AMD EPYC 9575F 64-core server.

Going back to April 2024, SiFive announced the HiFive Premier P550 as an interesting RISC-V developer board to succeed their HiFive Unleashed that was a nice little RISC-V board.
