Git 2.53 Released With More Optimizations, One Step Closer To Making Rust Mandatory

Phoronix - 16 hours 11 min ago
While we might see Git 3.0 released around the end of 2026, Git 2.53 is out today as the latest feature release and continuing to make changes with an eye toward that big Git 3.0 milestone...

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

Phoronix - 16 hours 29 min ago
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

Phoronix - Mon, 02/02/2026 - 22:48
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

Phoronix - Mon, 02/02/2026 - 21:51
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 translaction lookaside buffer (TLB) pressure without resorting to Hugetlbfs...
