Last week I provided some benchmarks looking at the IBM POWER9 mitigation for the L1 data cache needing to be flushed upon entering the kernel and on user accesses due to a recently disclosed vulnerability. POWER9 allows speculatively operating on validated data in the L1 cache, but when it comes to incompletely validated data paired with other side channels it could lead to local users potentially obtaining improper access to data in the L1 data cache. When benchmarking the impact on a POWER9 4c/16t CPU the overall impact was fairly modest while since then I fired up some benchmarks as well on a large POWER9 server with 44 cores / 176 threads to see the performance impact of this default Linux kernel change.

While we are still waiting to see what AMD might do for returning to open-source AGESA or better supporting Coreboot and the like, they are making some inroads with open-source firmware support -- beyond the context of Chromebooks where they continue to engage due to Google's engineering requirements. AMD is working to "align with the industry direction of open-source firmware stacks" with their initial focus being on open-source OpenBMC firmware support for their server platforms...

It was just in September that the C++20 standards draft was approved as a major update to the programming language over C++17. While compilers like GCC and LLVM Clang are still completing all of the changes for C++20 support, Clang is already moving ahead and has added support for the "-std=c++2b" option as it begins the endeavor of staging changes likely for C++23...

The BUS1 kernel code for providing an in-kernel, capability-based IPC mechanism hasn't seen much (or any?) activity in well over a year but at least the Dbus-Broker project continues ahead. Dbus-Broker continues ahead as this D-Bus compatible implementation focused on correctness while being optimized for performance...
