Vortex86 Processor Detection Landing For Linux 5.16

Recently I wrote about Vortex86 processors seeing detection work under Linux for improving the state of these aging x86 32-bit SoCs. That work is now slated to be introduced in the upcoming Linux 5.16 cycle for those running these aging SoCs/processors.

Intel Posts The "Last Part" To Their AMX Bring-Up For Linux

While for many years we have been accustomed to seeing Intel land their new hardware feature enablement work in the Linux kernel and related components well ahead of products shipping, occasionally there are lapses due to various internal and external timings. The launch of Sapphire Rapids is quickly approaching and one of the major additions is Advanced Matrix Extensions with its Linux support still being in the works.

An Early Look At The GCC 12 Compiler Performance On AMD Zen 3

GCC 12 isn't seeing its stable release until around March~April as usual, but with feature development slowly wrapping up as approaching the next stage of development next month to focus on fixes, recently I wrapped up some preliminary benchmarks for how GCC 12.0 is currently performing against GCC 11.2 on an AMD Ryzen 9 5950X (Zen 3) system.

AMD EPYC 7003 "Milan" Performance On Ubuntu Linux Six Months After Launch

It's been a half-year already since AMD introduced the EPYC 7003 "Milan" processors that continue performing well and gaining marketshare. While the recently released Ubuntu 21.10 is not a long-term support (LTS) release, for those wondering what this latest Linux distribution means for EPYC 7003 series performance, here is a look at its performance across many benchmarks against that of Ubuntu 21.04 that was released right after the Milan launch and then Ubuntu 20.04 as the current LTS stable series.

Intel Makes ControlFlag Open-Source For Helping To Detect Bugs In Code

Last year Intel announced ControlFlag as a machine learning tool for helping to uncover bugs within code. ControlFlag promised impressive results after being trained on more than one billion lines of code and at the end of 2020 was already being used internally on Intel's code-bases from firmware to software applications. We hadn't heard anything more about ControlFlag this year... Until today. Intel has now made ControlFlag open-source for helping to autonomously detect more programming bugs.

Radeon RX 6600 Linux Performance Rising Even Higher With Newest Open-Source Driver

Just one week ago was the public launch of the Radeon RX 6600 as the newest offering in the RDNA2 GPU line-up. While in our Radeon RX 6600 Linux review the performance was good on AMD's well regarded open-source driver stack and standing ground against the likes of the GeForce RTX 3060 with NVIDIA's proprietary Linux driver, it turns out the RX 6600 Linux performance can be even better already. Here are benchmarks of the Radeon RX 6600 on Linux across six different driver configurations.

Google Cloud Tau VM Instances Deliver Better Performance, Price-Performance Than Graviton2 M6g

Announced earlier this year for Google Cloud was a new family of virtual machines called Tau VMs. The initial T2D instances are powered by AMD EPYC 7003 "Milan" processors to deliver leading performance and are also positioned to deliver great value in going up against the likes of Amazon's Graviton2 instances. Tau VM instances are now available as a preview and Google has provided us with gratis access to the new instance types for benchmarking.

Google Developing "SiliFuzz" For Fuzzing CPUs To Uncover Electrical Defects

With OSS-Fuzz for continuous fuzzing of open-source projects and along with working on the various sanitizers for compilers, Google has been doing a lot for proactively uncovering software defects in key open-source projects. Now though a group of their engineers have been working on SiliFuzz for software aiming to discover new CPU defects.
