While the mainline Linux kernel has begun seeing initial support for various Snapdragon X1 Elite laptops, various feature limitations are outstanding before these Qualcomm-powered laptops really become usable for daily use. For instance, just a few days ago the audio firmware was finally upstreamed to make setting up X1 Elite laptops easier. Another important feature as an example is CPUFreq driver support for CPU frequency scaling to ensure optimal performance and power efficiency.

Ubuntu's Great Mainline Kernel PPA Hasn't Been Working Since Mid-September
Ubuntu's Great Mainline Kernel PPA Hasn't Been Working Since Mid-September
1 November 11:54 AM EDT - Ubuntu - Sad Face - 33 Comments

One of the very convenient features for Ubuntu Linux users who want to run the very newest upstream kernel releases or simply test a new kernel build for verifying bug fixes or functionality has been the Ubuntu Mainline Kernel PPA. It's been around for years, backed by Canonical, and very convenient for fetching pre-built AArch64 / ARM / POWER / RISC-V / x86_64 kernel binaries as Debian packages... With options of stable/test kernel versions as well as daily packages. Sadly, it's been broken once again and has been in that manner since mid-September.

Intel software engineers have been very busy recently with upstreaming various elements of support into the Linux kernel, open-source compilers and more for the next-generation Xeon Diamond Rapids processors. Following the recent GCC prep patches for Diamond Rapids to work on the ISA additions around AMX-AVX512, AMX-FP8, AMX-FP32, and others, a new patch was posted today for actually exposing the "-march=diamondrapids" compiler target and in turn confirming all of the new ISA capabilities.

AMD EPYC 9655 Benchmarks Show The Terrific Generational Gains With 5th Gen EPYC
31 October 12:26 PM EDT - Processors - 14 Comments

With the AMD EPYC 9005 "Turin" series launch earlier this month there was launch-day benchmark review results for the EPYC 9575F, EPYC 9755, and EPYC 9965 processors in looking at that frequency optimized SKU, the new flagship 128-core Turin "classic" core model, and the new flagship 192-core Turin "dense" core SKU, respectively. That's interesting for looking at the new 5th Gen AMD EPYC top-end wares but in comparing to 4th Gen EPYC also means higher core counts at the top-end. In being curious about the core-for-core advantages of 5th Gen EPYC, I managed to get my hands on the AMD EPYC 9655 processors for seeing how that model compares to the prior AMD EPYC 9654 "Genoa" flagship model. Here's a look today at how the AMD EPYC 9655 1P/2P 96-core processor compares to the prior EPYC 9654 flagship.

AMD "Cleaner Shader" Coming For GFX11.0.3 GPUs To Help Ensure User/App Isolation
30 October 08:27 PM EDT - Radeon - AMD Cleaner Shader - 11 Comments

A new patch posted today for the AMDGPU Linux kernel graphics driver is introducing a "cleaner shader" explicitly for GFX11.0.3 GPUs like the Radeon 780M integrated graphics to help ensure that there is sufficient data isolation between different workloads running on the GPUs. The motivation isn't clear if there is some GFX11.0.3 security vulnerability, some AMD Linux customer particularly concerned about security on said GPUs, or some other motivation for focusing this latest cleaner shader work on GFX11.0.3 hardware.
