Last week the AMD Inception vulnerability was made public as a speculative side channel attack affecting Zen processors and different mitigation options based on the CPU generation. There wasn’t too much communication around the performance implications of mitigating Inception while over the past week I have begun benchmarking the software and microcode updates on Ryzen and EPYC processors.

While Linux 6.1 added the initial Rust infrastructure as an alternative programming language for writing new kernel modules, so far as of Linux 6.5 much of the upstreaming effort has been around adding new abstractions and supporting additional subsystems for making the Rust capabilities in the kernel more complete. The latest patch series is working on adding Rust abstractions for networking sockets and other fundamental networking bits…
