New Rust-Based BUS1 In-Kernel IPC In Development For The Linux Kernel

Phoronix - Wed, 04/01/2026 - 03:47
After KDBUS failed to make it into the mainline Linux kernel more than one decade ago as an in-kernel version of D-Bus, BUS1 was proposed as a clean sheet design for in-kernel, capability-based inter-process communication (IPC). BUS1 didn't gain enough traction to make it to the mainline kernel and then many of the same developers devised Dbus-Broker as a more performant D-Bus user-space implementation. Well, as a big surprise now, a new version of BUS1 is being worked on for the Linux kernel...

Meta Optimizing /proc/interrupts Reading As It's Too Costly At Scale: 29% Speedup

Phoronix - Tue, 03/31/2026 - 21:03
One of the latest Linux kernel optimizations being worked on by Meta's large kernel engineering team is making reading of /proc/interrupts less costly. Due to monitoring of their servers frequently reading /proc/interrupts, it's actually become a noticeable cost over time with their massive fleet of systems...
