For several years now Facebook engineers have been working on BOLT as a way to speed-up Linux/ELF binaries. This "Binary Optimization and Layout Tool" is able to re-arrange executables once profiled to generate even faster performance than what can be achieved by a compiler's LTO and PGO optimizations. One of the latest BOLT efforts has been on optimizing the Linux kernel image...

Earlier this month Intel engineers posted their initial Linux kernel enablement around x86 User Interrupts with this feature premiering with Xeon "Sapphire Rapids" CPUs. As implied by the name, the User Interrupt functionality allows for interrupts to bypass the kernel for more efficient, low-latency, low-utilization interrupts being received by other user-space tasks. Intel talked more about User Interrupts this week at LPC2021...

A few weeks ago I finally received the HiFive Unmatched from SiFive as their flagship RISC-V development board. As a reminder this is their mini-ITX development board that is powered by their U740 SoC and features 16GB of DDR4 system memory, one PCI Express x16 slot that can work with AMD Radeon graphics cards on Linux, and other features. It's been a delight playing with this developer platform and enclosed are some early benchmarks as well showing off the U740 performance as well as how the Linux software support/performance has been evolving.
