Linux's V4L2 VP9 Codec Kernel Code Rewritten In Rust For Better Memory Safety

Wed, 02/28/2024 - 09:12
Daniel Almeida with Collabora has posted a rewritten of the VP9 codec library code within the Linux kernel's Video 4 Linux 2 (V4L2) subsystem. In using Rust rather than the existing C code, this should yield better memory safety and better fend off potential issues within the existing code...

64K Kernel Page Size Performance Benefits For HPC Shown With NVIDIA's GH200 Grace CPU

Wed, 02/28/2024 - 01:00
By default the AArch64 kernel on Ubuntu and other Linux distributions tend to default to a standard 4K page size but for newer AArch64 hardware especially in the server/HPC space, there can be great benefits to using a 64K page size. As it's been a while since I last ran any 64-bit ARM 4K vs. 64K kernel page size benchmarks, while having remote access to the NVIDIA GH200 I ran a fresh comparison for looking at the performance advantages to switching over to a 64K page size kernel. These new 64K kernel numbers are shown alongside the recent AMD EPYC and Intel Xeon CPU reference benchmark results for a look at how the 4K vs. 64K page size affects the overall computing landscape.

Intel HFI Driver Can "Save Tons Of CPU Cycles" By Only Enabling Itself When Needed

Tue, 02/27/2024 - 19:42
The Linux kernel has supported the Intel Hardware Feedback Interface "HFI" via the "intel_hfi" driver since 2022 for bettering supporting Core hybrid processors. The Intel HFI can be used for communicating performance and energy efficiency capabilities of individual CPU cores of the system. In turn the Linux kernel can leverage Intel HFI details for better task placement among the available CPU cores/threads. With a new patch series, the Intel HFI driver can "save tons of CPU cycles" by only enabling it when needed...

Ubuntu Blog Talks Up Rust Schedulers, Potential For Micro-Kernel Design Future

Tue, 02/27/2024 - 09:27
Ubuntu/Canonical has for a while now promoted the prospects of Rust programming within the Linux kernel and one of their kernel engineers, Andrea Righi, wrote a Rust-written Linux scheduler with promising results that leverages eBPF for dynamically loading it at run-time. While Ubuntu isn't yet committing to using it as part of their distribution, appearing on the Ubuntu blog today was more praise for the work and even talking about the potential for a "micro-kernel design" in the future via leveraging Rust and eBPF...
