While the Linux kernel itself may not be often viewed as a bottleneck to typical high performance computing (HPC) workloads, optimizing the Linux kernel with Profile Guided Optimizations (PGO) can prove worthwhile for those seeking maximum performance potential. A presentation this past weekend at FOSDEM 2025 is highlighting around a 3% performance gain for HPC software compiled with PGO enabled...

The Ubuntu Mainline Kernel PPA for years has been a great feature for Ubuntu users to be able to easily fetch and run the newest upstream kernel whether it's the latest stable kernel version, one of the weekly release candidates, or even the very leading-edge daily Git kernel builds. Sadly for months now this service has been out of order...

Initially merged back for the Linux 6.13 kernel was EXECMEM_ROX support for module text on x86_64 systems. With this caching of large ROX pages it can help with lowering TLB instruction pressure and enhancing performance. But this EXECMEM_ROX support that was contributed by a Microsoft engineer ended up being reverted in the final days of Linux 6.13. The revert came due to bugs and not having any Linux x86 maintainers signing off on the code. This code has been getting into shape for trying again with the mainline kernel...
