Bhyve is the BSD hypervisor / virtual machine manager (VMM) developed by FreeBSD that supports a range of operating systems and across CPU vendors. With time Bhyve has also been ported to other BSDs and even Illumos and macOS. The Linux kernel is now in the process of adding guest detection for the Bhyve hypervisor in order to support VMs with 255+ vCPUs...

While the Linux v6.17 merge window only wrapped up earlier this month, Apple Silicon DeviceTree "DT" updates have already begun queuing for the Linux 6.18 merge window that will happen in October...

We still don't have much confirmed information on AMD's GFX1250 that has come to light in recent months due to being developed for their AMDGPU shader compiler back-end within LLVM. AMD GFX1250 surfaced in LLVM activity and the past few months has been seeing more additions made. A notable change committed today for LLVM is that the number of user Scalar General-Purpose Registers (SGPRs) has doubled...

Following the AMD ZenDNN 5.0 release from last year's EPYC Turin launch that brought big performance improvements for CPU-based inferencing with this open-source library compatible with Intel's oneDNN, today marks the availability of ZenDNN 5.1 as the next update...

Git 2.51 is out this Monday as the newest milestone for this widely-used, distributed version control system...

The Framework Desktop is a nifty and powerful mini PC powered by AMD Ryzen AI Max "Strix Halo". It's been a pleasure testing this small yet powerful Linux-friendly system that easily offers much better performance than the Intel Core Ultra 9 and superb energy efficiency. For complementing the data shared earlier this month in our Framework Desktop review, today's article is a deep dive into the power and thermals of the Framework Desktop in a few different configurations.

One of the areas worked on by AMD Linux engineers recently to better optimize the Linux kernel on AMD Ryzen platforms is for lowering the power consumption in S5 state due to some devices not being put into a low power state when the system is powered off. Sent out today was the sixth iteration of these patches...

The Firefox 142.0 release binaries are now available ahead of the official release announcement due out on Tuesday. Firefox 142 isn't bringing many notable changes but one is likely to cause some contention around Firefox Extensions...

Linux 6.17-rc2 is now available to facilitate the latest weekly testing of the Linux 6.17 kernel...

Last week I ran some early Linux 6.17 benchmarks showing some improvements and regressions when testing with AMD Ryzen AI Max "Strix Halo". Since then there have been some performance regression fixes along with addressing other early fallout from this fresh kernel code. Repeating the tests now on the latest Linux 6.17 Git state ahead of today's Linux 6.17-rc2 tagging is showing some nice improvements and fixes from the code churn this week...

One of the new exciting security features with Linux 6.17 is Attack Vector Controls as a means of easier managing CPU security mitigations depending upon the system/server use-case. It drastically simplifies CPU security mitigation management for only activating the mitigations relevant to intended use. With the Linux 6.17-rc2 kernel due out later today, Attack Vector Controls refines its logic around the Speculative Return Stack Overflow (SRSO) mitigation...
