IT & infrastructure

Operational fixes and low-level plumbing dominated. Microsoft resolved two Windows 11 update regressions, and Cloudflare shared a detailed debugging write-up. Optical and data center hardware stories pointed to constraints on bandwidth and land.

• [$] Collaborating with out-of-tree tracers3

  At Linux Plumbers 2026, Mathieu Desnoyers discussed barriers to merging the LTTng tracer with mainline kernel tracing efforts.

  Feed excerpt

  LTTng creator Mathieu Desnoyers seems a bit trapped in something of a catch-22. At the 2026 Linux Plumbers Conference (LPC), he led a discussion on the problem he is having in trying to collaborate with other tracing projects (e.g. ftrace, perf) in the kernel. The feedback he has gotten, both over the years and more recently, does not show a path that would allow him to contribute the 21-year-old GPLv2-licensed LTTng tracing framework, or, incrementally, features from it, to the mainline kernel.

• Huawei Proposes Enabling CPU Boost By Default For ACPI CPPC Linux Driver2

  Huawei has proposed enabling CPU boost mode by default in the generic ACPI CPPC Linux cpufreq driver used on ARM64 servers.

  Feed excerpt

  For those using the generic ACPI Collaborative Processor Performance Control (CPPC) CPUFreq driver such as on a number of ARM64 Linux server platforms, if the CPUs support a "boost" mode it's disabled by default. But a patch from Huawei is now looking to enable CPU boost mode by default on Linux...
