Linux 7.0 Apple Silicon Device Tree Updates Have All The Bits For USB Type-C Ports

21. Leden 2026 - 15:18
Ahead of the Linux 6.20~7.0 cycle kicking off next month, the Apple Silicon Device Tree updates have been sent out for queuing ahead of that next merge window. Notable this round are the Device Tree additions for rounding out the USB 2.0/3.x support with the USB-C ports...

Adjusting One Line Of Linux Code Yields 5x Wakeup Latency Reduction For Modern Xeon CPUs

21. Leden 2026 - 12:27
A new patch posted to the Linux kernel mailing list aims to address the high wake-up latency experienced on modern Intel Xeon server platforms. With Sapphire Rapids and newer, "excessive" wakeup latencies with the Linux menu governor and NOHZ_FULL configuration can negatively impair Xeon CPUs for latency-sensitive workloads but a 16 line patch aims to better improve the situation. That is, changing one line of actual code and the rest being code comments...

New Linux Patch Improved NVMe Performance +15% With CPU Cluster-Aware Handling

20. Leden 2026 - 23:51
Intel Linux engineers have been working on enhancing the NVMe storage performance with today's high core count processors. Due to situations where multiple CPUs could end up sharing the same NVMe IRQ(s), performance penalties can arise if the IRQ affinity and the CPU's cluster do not align. There is a pending patch to address this situation. A 15% performance improvement was reported with the pending patch...
