One of the most common Linux hardware questions I've received dozens of times in the past few weeks alone has been over the support for "RX Vega M" Vega-based graphics processors found on select newer Intel Kabylake CPUs. It appears RadeonSI at least should now support these Radeon graphics on Intel CPUs...
Besides the fresh BSD/Linux disk performance tests, some other tests I ran on various BSDs and Linux distributions this week was looking at the performance impact of Intel Meltdown CPU vulnerability mitigation on each of them, namely the performance impact of using kernel page-table isolation...
With the recent release of DragonFlyBSD 5.2 one of the prominent changes is HAMMER2 now being considered stable for most use-cases. I've been running some benchmarks of this file-system compared to alternatives on other operating systems and have some FreeBSD / Linux reference points to share...
With the RADV Mesa Radeon Vulkan driver continuing to be advanced by Valve and other independent developers while AMD continues with open-source code drops of their official AMDVLK Vulkan driver, it's been a friendly open-source Radeon Vulkan driver performance and feature/extension battle since that official AMD Vulkan driver was opened up at the end of last year. With new AMDVLK/XGL/PAL code drops happening about weekly and RADV continuing to receive new feature/performance work every few days, both drivers continue maturing gracefully as shown by our latest performance benchmarks.

Just one week after launching Red Hat Enterprise Linux 7.5, Oracle has released the latest version of their RHEL7-derived Oracle Linux 7. The Oracle Linux 7 Update 5 pulls in the latest *EL7 changes while also offering their "Unbreakable Enterprise Kernel" option...
With last week's release of Feral GameMode as a system tool to optimize Linux gaming performance, which at this point just toggles the CPU frequency scaling driver's governor to the "performance" mode, reignited the CPU governor debate, here are some fresh Linux gaming benchmarks. Tests were done with both the CPUFreq and P-State scaling drivers on Linux 4.16 while testing the various governor options and using both AMD Radeon and NVIDIA GeForce graphics cards.
Of the many great features/changes for Linux 4.17, one of the most exciting to us is the idle power efficiency and performance-per-Watt improvements on some systems thanks to a rework to the kernel's idle loop handling. Rafael Wysocki and Thomas Ilsche as two of the developers working on this big code change presented on their work today for this CPU idle loop ordering problem and its resolution...
Earlier this month Intel ISA documentation pointed to a new CPU micro-architecture codenamed "Tremont", we've seen a few kernel patches also referencing Intel Tremont, and now there is Tremont microarchitecture support for LLVM's Clang compiler...
While back in 2015 there was Azure Cloud Switch as Microsoft's first foray into having their own Linux distribution that handles networking within their Azure data centers, today they have announced their Azure Sphere product for IoT use-cases and it's powered by Linux...
AMD kicked off the start of a new week by doing fresh code drops of the PAL and XGL code-bases used to form the AMDVLK open-source Radeon Vulkan Linux driver...
Texas Instruments is still dealing with Imagination Tech PowerVR SGX GPUs and has now posted an open-source DRI3 WSEGL plug-in for getting this binary blob to work with 3D acceleration under an X.Org Server using Direct Rendering Infrastructure 3...
While the Linux 4.17 merge window officially closed yesterday with the release of Linux 4.17-rc1, FUSE maintainer Miklos Szeredi is now trying to get his changes added...
Phoronix Test Suite 8.0 Milestone 3 is now available for evaluation as the latest step towards the official 8.0-Aremark release due out later this quarter...
Of the many improvements to be found in the in-development Linux 4.17 kernel -- nicely summarized in our Linux 4.17 feature overview -- one of the features I've been anxious the most to begin benchmarking has been the reported power management improvements. Here are my initial power/performance tests of Linux 4.17 that for some systems is seeing a measurable drop in power usage, even in some cases under load while without sacrificing the performance.
Mesa 18.0.1 is being planned for release on Wednesday as the first stable point release / maintenance update for this quarterly installment to Mesa 3D...
While the Linux 4.17 kernel merge window is closing today and is already carrying a lot of interesting changes as covered by our Linux 4.17 feature overview, Thomas Gleixner today sent in a final round of x86 (K)PTI updates for Meltdown mitigation with this upcoming kernel release...
Besides looking at the HAMMER2 performance in DragonFlyBSD 5.2, another prominent change with this new BSD operating system release is the Spectre and Meltdown mitigations being shipped. In this article are some tests looking at the performance cost of DragonFlyBSD 5.2 for mitigating the Meltdown Intel CPU vulnerability...
Linus Torvalds is expected by the end of the day to release Linux 4.17-rc1, thereby marking the end of the two-week merge window that saw a lot of changes and new features land for Linux 4.17. Here is our original feature overview of the changes to be found in this next major release of the Linux kernel, which should premiere as stable by the middle of June.

With this week's release of DragonFlyBSD 5.2 this popular BSD operating system is promoting its own HAMMER2 file-system as stable. As a result, here are a few fresh benchmarks of HAMMER vs. HAMMER2 on DragonFlyBSD 5.2 while more tests are forthcoming.
With the RADV Vulkan driver recently landing improvements to its out-of-order rasterization support, I ran some performance benchmarks of this non-default feature to see if it made much of a deal for today's Vulkan Linux games...
