Security Researchers Find Current RISC-V CPU Implementations Coming Up Short

2 février 2026 à 18:19
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...

Loongson 3B6000 Benchmarks: How China's LoongArch CPU Compares To AMD Zen 5, Intel Arrow Lake & Raspberry Pi 5

2 février 2026 à 15:48
Recently I finally got my hands on a LoongArch processor, the ISA developed by China's Loongson Technology as an evolution from their earlier use of the MIPS64 ISA and inspired by RISC-V and other modern ISAs. The Loongson-3B6000 features 12 cores / 24 threads with dual channel DDR4 ECC memory support. Here is a look at how that latest-generation LoongArch desktop processor compares to the current generation AMD Zen 5 and Intel Arrow Lake desktop processors under Linux. Plus also tossing in the Raspberry Pi 5 (Raspberry Pi 500+) for an ARM reference point.

Experimental Linux Code For 1GB PUD-Level THPs Shows 34% Faster Memory Access Times

2 février 2026 à 14:51
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...

Rust Coreutils Continues Working Toward 100% GNU Compatibility, Proving Trolls Wrong

2 février 2026 à 12:32
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. Ledru has spoken at FOSDEM in prior years on Rust Coreutils and this year's talk focused primarily on Ubuntu 25.10's adoption of it in place of GNU Coreutils...

Linux 6.19-rc8 Released Ahead Of Linux 6.19 Stable Next Week

1 février 2026 à 23:39
While typically the stable Linux kernel would come after the -rc7 release a week prior, for Linux 6.19 the release is being dragged out by an extra week not due to any scary bugs but rather due to the holiday downtime at the end of the year. As such Linux 6.19-rc8 is out today with the stable v6.19 release expected next Sunday...

GNU Hurd Is "Almost There" With x86_64, SMP & ~75% Of Debian Packages Building

1 février 2026 à 16:47
Samuel Thibault offered up a status update on the current state of GNU/Hurd from a presentation in Brussels at FOSDEM 2026. Thibault has previously shared updates on GNU Hurd from the annual FOSDEM event while this year's was a bit more optimistic thanks to recent driver progress and more software now successfully building for Hurd...

cTGP Graphics Power Setting Coming For Uniwill / TUXEDO Laptops With Linux 7.0

1 février 2026 à 12:22
Upstreamed for the Linux 6.19 kernel is the Uniwill laptop platform driver for exposing more features/settings for laptops made by this Taiwanese OEM/ODM, including the laptops from TUXEDO Computers. Coming for the next kernel cycle is further extending the Uniwill platform driver for now having support for adjusting the custom total graphics power "cTGP" for those laptops with a dedicated GPU...

Linux 7.0 Aims To Replace More Caching Code With Sheaves For "Hopefully" Improved Performance

1 février 2026 à 02:08
Introduced to the mainline Linux kernel last year was "sheaves" as an opt-in per-CPU array-based caching layer. Sheaves was merged back in Linux 6.18 and while it started as an opt-in caching layer, the plan is to replace more CPU slabs / caches with sheaves. Queued up for slated introduction in the upcoming Linux 7.0 cycle is replacing more of those caches with sheaves...

Linuxulator-Steam-Utils To Enjoy Steam Play Gaming On FreeBSD & Other Options

31 janvier 2026 à 18:36
Presented today at FOSDEM in Brussels was the state of gaming on FreeBSD by Thibault Payet. Besides various open-source games able to be compiled natively for FreeBSD, this BSD can get in on the Steam Play gaming scene thanks to the "linuxulator-steam-utils" project as a set of workarounds for the Steam Linux client on FreeBSD 14 and newer. Linuxulator-steam-utils builds off FreeBSD's Linuxulator support for running Linux binaries to enjoy the likes of Steam and even Steam Play (Proton) Windows games running on this translation layer for Linux and in turn running on FreeBSD...
