Intel Finds Great Performance With PostgreSQL's AVX-512 Support

13 novembre 2025 à 02:44
Back in April PostgreSQL added AVX-512 support for CRC32 computations. At the time the gains for CRC32 computations with this popular open-source database server were reported to be 50% to 3x faster for x86_64 CPUs able to leverage AVX-512. That AVX-512 support is found with PostgreSQL 18.0 that released in September and now Intel is praising this addition to PostgreSQL for which their developers also had a part in along with AWS and others...

Valve's Open-Source Radeon Linux Driver "Love Song For Gamers With Old GPUs"

12 novembre 2025 à 16:13
As covered recently on Phoronix there has been several exciting improvements for aging AMD Radeon GCN 1.0 and GCN 1.1 era graphics cards for the open-source AMD Linux graphics driver stack. This work has been led by Timur Kristóf of Valve's Linux Open-Source Graphics Driver Group with an ultimate goal of shifting the GCN 1.0/1.1 open-source Linux driver hardware support from the aging "Radeon" kernel graphics driver over to the "AMDGPU" kernel driver already used by default for all AMD GPUs/accelerators from GCN 1.2 and newer...

sudo-rs Affected By Multiple Security Vulnerabilities - Impacting Ubuntu 25.10

11 novembre 2025 à 23:32
The Ubuntu 25.10 transition to using some Rust system utilities continues proving quite rocky. Beyond some early performance issues with Rust Coreutils, breakage for some executables, and broken unattended upgrades due to a Rust Coreutils bug, it's also sudo-rs now causing Ubuntu developers some headaches. There are two moderate security issues affecting sudo-rs, the Rust version of sudo being used by Ubuntu 25.10...

Linux Proposal Aims To Overcome Kernel Limitation Affecting Various Gaming Peripherals

11 novembre 2025 à 18:39
The Linux kernel's Human Interface Devices (HID) subsystem has an existing architectural limitation that there is just up to one battery per HID device. But with modern devices -- especially among various gaming peripherals -- there can be more than one battery when considering earbuds with a battery for each earbud, multi-device wireless receivers, etc. A proposal was raised today to address this limitation...

Intel Core Ultra 7 255H Linux CPU Performance

11 novembre 2025 à 16:40
Lenovo recently sent over their new ThinkPad P1 Gen 8 laptop for review under Linux. My Linux review on that ThinkPad P1 Gen 8 laptop will be coming up in the near future along with some other benchmarks from that premium mobile workstation. But with this being the first time I've had an Intel Core Ultra 7 255H "Arrow Lake H" device at Phoronix, here are some standalone benchmarks looking at the CPU performance of that 16-core mobile processor compared to various other Intel and AMD SoCs in different laptops while running Ubuntu Linux.
