Linux Hardware Reviews & Performance Benchmarks, Open-Source News

While there is the Linuxulator as a kernel-level solution on FreeBSD for running unmodified Linux binaries that can even work for gaming on FreeBSD, running BSD applications on Linux isn't talked about as much. But developers have found that for those wanting to run BSD applications in Linux environments, the urunc lightweight container runtime can work out rather well for efficiently handling BSD apps on Linux.

A few months ago at SIGGRAPH was a demo of Blender with NVIDIA Deep Learning Super Sampling (DLSS) integration. The pull request is now open for landing NVIDIA DLSS support into Blender for better quality upscaling/denoising and performance but concerns persist over the licensing due to NVIDIA DLSS binaries.

Merged four years ago to the Linux kernel networking subsystem's Shared Memory Communications (SMC) code was TCP Upper Layer Protocol (ULP) support for allowing applications to replace TCP with the SMC protocol in-place as a transparent replacement. Except for the next kernel cycle it's set to be reverted after realizing it's "fundamentally broken."

OpenIndiana as the open-source project built atop Illumos that is continuing to maintain and advance the former OpenSolaris code is working on a big ambitions of modernizing the Image Packaging System (IPS) package management solution. As part of that they are working to move from a C and Python codebase over to Rust.

Announced back in October was NTFS Plus as a new Linux driver for NTFS based on the former NTFS kernel driver prior to Paragon Software contributing the NTFS3 driver code.

2 February 12:19 PM EST - RISC-V - RISC-V Insecurities

While many open-source enthusiasts like to flaunt RISC-V as not having the security challenges as x86_64 CPUs have seen over the past several years with various speculative execution / side-channel attacks and arguing for the benefits of an open-source ISA in stronger security, in practice it's not so clear-cut. Security researchers at Germany's CISPA Helmholtz Center for Information Security have found current RISC-V CPU implementations coming up short for their actual security.

Early, experimental code for implementing 1GB PUD-level THPs in the Linux kernel are showing positive benchmark results but other upstream stakeholders were surprised by this patch series appearing and it looking like it could be a while until if/when the patches are mainlined for helping to reduce transaction lookaside buffer (TLB) pressure without resorting to Hugetlbfs.

Sylvestre Ledru who serves as the lead developer of the uutils project for the Rust Coreutils implementation presented at FOSDEM 2026 this weekend on this initiative.
