AMD 4th Gen EPYC "Genoa" To Enjoy Slightly Better Performance With Linux 6.3
www.phoronix.com
AMD's upcoming 4th Gen EPYC "Genoa" processors are expected to benefit from Automatic IBRS, a new feature in the Linux 6.3 kernel. This feature provides better performance than the current Retpolines implementation for mitigating Spectre V2. The Automatic IBRS support is new to Zen 4 processors and will be enabled by default in Linux 6.3. Benchmarks on the AMD EPYC 9654 server processors show the performance improvement with Automatic IBRS. This feature is similar to Intel's Enhanced IBRS and will be available on both client and server CPUs. The patches for enabling Automatic IBRS have been in the works since November and are now being finalized for the upcoming kernel release.
