Linux Lands Fix For Potentially Bogus Number Of Intel Hybrid CPU HT Siblings
Linux Lands Fix For Potentially Bogus Number Of Intel Hybrid CPU HT Siblings
10 Hours Ago - Intel - Fixed For Linux 6.4-rc4 - 1 Comment

A few days ago I wrote about a Linux kernel patch being prepared for fixing Intel hybrid CPU SMP/HT topology reporting due to the way the Linux kernel was currently counting the number of Hyper Threading siblings for each core. Fortunately, that fix which is apparently becomes more pressing for upcoming Meteor Lake processors, has now been picked up in time for today's Linux 6.4-rc4 release and is set for back-porting to stable kernel series.

Linux Preps Hybrid SMP Fix To Avoid Upcoming Laptops Appearing As 11 Socket Monsters
Linux Preps Hybrid SMP Fix To Avoid Upcoming Laptops Appearing As 11 Socket Monsters
26 May 08:17 AM EDT - Linux Kernel - Hybrid SMP Topology Fix - 7 Comments

A fix is on its way to the mainline Linux 6.4 kernel and also marked for back-porting to existing stable kernel series to fix x86 topology reporting for Intel Hybrid systems. The topology bug within the kernel becomes more pronounced for Meteor Lake laptops where currently internal Intel test laptops can report the systems having 11 CPU sockets rather than the proper number of cores all contained within one CPU socket.

Big Throughput Boost & Lower Latency With New Patch For Linux Checksum Function
Big Throughput Boost & Lower Latency With New Patch For Linux Checksum Function
26 May 06:21 AM EDT - Linux Kernel - csum_partial - 12 Comments

Queued up ahead of the Linux 6.5 cycle kicking off in about one month is a new Linux x86 optimization patch for further tuning csum_partial, the function used within the kernel for calculating 32-bit checksums on blocks of data. Much lower latency and higher throughput can be observed with the newly-optimized csum_partial on the latest Intel/AMD processors.

Intel Engineers Revise Key Locker Implementation For Linux
Intel Engineers Revise Key Locker Implementation For Linux
25 May 08:03 AM EDT - Intel - Intel Key Locker v7 - 4 Comments

Going back to 2020 has been work by Intel's open-source engineers on implementing Key Locker support for Linux. Intel Key Locker allows for encrypting/decrypting data with an AES key without having access to the raw/actual key. AES keys are converted into handles with Intel Key Locker that can then be used for carrying out encryption/decryption on that system until revoked or system state changes. Intel engineers on Wednesday posted their seventh iteration of the patches for supporting Key Locker on Linux.

Intel's Open Image Denoise 2.0 Brings SYCL For Xe GPUs, NVIDIA CUDA, AMD HIP
24 May 06:47 PM EDT - Intel - Open Image Denoise 2.0 - 5 Comments

Among Intel's dozens of terrific open-source components -- including the many components making up their oneAPI software suite -- is Open Image Denoise. Open Image Denoise for years has been a terrific, high-performance denoising library for ray-tracing use The software has long been CPU-based while being highly performant thanks to leveraging modern instruction set extensions. Today though Open Image Denoise 2.0 is released and brings GPU acceleration across Intel, AMD, and NVIDIA graphics processors.

Fedora's RPM Fusion Adds Experimental Intel IPU6 Web Camera Support
24 May 12:00 PM EDT - Intel - Fedora IPU6 Camera Support - 10 Comments

The Intel IPU6 web camera tech found in Alder Lake laptops and newer has unfortunately no upstream Linux driver yet and has resulted in kernel developers avoiding these laptops where web camera support is needed. Intel maintains an out-of-tree IPU6 Linux driver while they have been making progress toward ultimately getting it upstreamed. To ease the situation for Fedora Linux users, an experimental IPU6 software stack has now been added to the RPM Fusion repository.

AMD Radeon RX 7600 Linux Performance
24 May 09:00 AM EDT - Graphics Cards - 54 Comments

For those that have been interested in the Radeon RX 7900 series for the great open-source driver support on Linux but have been wanting a cheaper graphics card and perhaps are a 1080p gamer, today's launch of the Radeon RX 7600 will surely be of interest to you. The Radeon RX 7600 is a nice lower-end graphics card for 1080p gamers and has upstream open-source Linux support already -- including the ability to run out-of-the-box already on Ubuntu 23.04 and other newer distributions. Here is my Linux performance review of the AMD Radeon RX 7600.

AMD CPU "k10temp" Linux Driver Updated To Report Negative Temperatures
23 May 05:15 PM EDT - AMD - AMD k10temp Negative Temps - 22 Comments

The AMD k10temp Linux driver is used for CPU temperature reporting with all modern AMD Ryzen/EPYC processors plus going back all the way to many earlier FX / Athlon / Sempron / Opteron / Phenom CPUs starting with the Family 10h line-up. While this driver has been in the Linux kernel for years, it's carried a limitation until now that it can't handle reporting negative temperatures. That is changing thanks to new patches from AMD.

Fedora Developers Discuss An Idea For Using U-Boot On x86 BIOS Systems
23 May 08:30 AM EDT - Fedora - Fedora + U-Boot + x86 BIOS Platforms - 15 Comments

Last year Fedora and Red Hat developers began discussing the idea of dropping legacy BIOS support and to then only focus on UEFI platforms. There was a plan to deprecate BIOS support in Fedora 37 but ultimately it didn't go through due to some cloud providers still booting VMs in BIOS mode and some systems having broken UEFI implementations. An idea has now been raised over the possibility of using U-Boot on x86 BIOS systems to provide a UEFI-like experience from the Fedora perspective.
