Cloud Hypervisor as what started out as an Intel open-source project and now lives under the Linux Foundation umbrella as a virtual machine monitor (VMM) for use with Linux KVM and Windows MSHV is out with a new feature release...

Following last week's release of Vulkan 1.3.219 that introduced the VK_EXT_shader_module_identifier extension and Mesa's Radeon Vulkan driver (RADV) adding support for it earlier this week, Intel's open-source Vulkan driver "ANV" has landed support for this new extension to close out the week...

The past few months we have been closely covering the Coreboot port to an MSI retail motherboard for Intel Alder Lake. This port carried out by the 3mdeb consulting firm has been with their downstream "Dasharo" firmware based on Coreboot while as of yesterday the motherboard port has begun landing in upstream Coreboot...

Canonical engineers have been continuing their quest to improve the start-up time for the Snap version of Mozilla Firefox that is used by default on Ubuntu 22.04 LTS. With the latest improvements now pushed to the Firefox Snap, they are seeing around a 50% reduction in start-time for the web browser...

Last year when the Intel Core i9 12900K "Alder Lake" processor launched, Windows 11 was outperforming Linux to much surprise in general but explainable due to some late Linux kernel patches around Intel's hybrid architecture. Back in February I looked at the situation again and Linux started outrunning Windows 11 on the i9-12900K with the latest Linux kernel at the time. But with a few more months having passed and for the Intel Alder Lake hybrid processors to mature under Windows and Linux, how do things stand now? Here are some new benchmarks.

With the upcoming feature-packed Linux 5.20 kernel adding to the growing list of features is Intel SGX2 support looking like it is set to land...

At least some of Lenovo's new AMD Rembrandt powered laptops with Microsoft Pluton security co-processor are set by default to only trust Microsoft's key and not the Microsoft 3rd Party UEFI CA Key that Linux distributions and others use for UEFI Secure Boot support. Thus by default only Microsoft Windows will boot with the default firmware configuration on some new Lenovo laptops...

From the recent setup of the MSI Alder Lake motherboard flashed with Dasharo/Coreboot I had an extra LGA-1700 motherboard around. With some Phoronix readers in the past having inquired about more Alder Lake benchmarks on the low-end, I picked up a Core i3 12100 processor that features four performance cores / eight threads. For those curious about the CPU performance and that of the integrated UHD Graphics 730, here are some Ubuntu Linux performance benchmarks with the i3-12100 and other similar processors.

Mesa 22.2 as the quarterly feature update to this collection of open-source predominantly OpenGL and Vulkan graphics drivers has been pushed back by two weeks. This delay is for allowing more last minute features to land, which will hopefully ensure that Intel Arc Graphics and RDNA3 support is in better shape for this release...

As time goes on more open-source projects are beginning to make better use of AVX-512 support even though it's no longer enabled in the latest Alder Lake processors. After reporting on the big AVX-512 wins for JSON parsing with simdjson, another open-source project finding gains is the Tesseract optical character recognition (OCR) engine...

It turns out he had joined Microsoft and continuing his work on systemd...

In addition to Intel's open-source Linux graphics driver developers being very busy rounding out their DG2/Alchemist enablement patches, beginning to mainline "Ponte Vecchio" work starting with Linux 5.20, and having already done the bit of enablement for Raptor Lake graphics that is predominantly based on existing Alder Lake, they have also started their Meteor Lake bring-up...

The SUSE/openSUSE Adaptable Linux Platform (ALP) that is being viewed as the eventual successor to SUSE Linux Enterprise 15 is likely to require higher system requirements for x86_64 CPUs. Just how much newer the Intel/AMD support requirement will be has yet to be firmly decided but they are looking at a baseline of "x86-64-v3" that would effectively mean requiring Advanced Vector Extensions (AVX)...

Last week's Vulkan 1.3.219 release introduced the VK_EXT_shader_module_identifier that was worked on in part by Valve. This ability for software to query an identifier associated with a Vulkan shader module is seeing quick driver adoption and is preparing for use within VKD3D-Proton as an efficiency improvement...

Given the recent releases of openSUSE Leap 15.4 and AlmaLinux 9.0, here are some fresh Linux server/workstation-oriented benchmarks on a dual Intel Xeon Platinum 8380 "Ice Lake" platform and running the fresh releases of various enterprise Linux choices.

For as popular as the Raspberry Pi 4 has been since its 2019 launch, Fedora hasn't officially supported this Arm single board computer with its Linux distribution. But now thanks to the upstream, open-source graphics acceleration finally coming together for the Raspberry Pi 4, with Fedora 37 they may end up finally providing "official" support for this popular, low-cost developer board...

The past few weeks I have been testing out this Raspberry Pi powered device and indeed it opens the door for using the Raspberry Pi within more harsh and demanding environments.

I'm currently working on a fresh comparison of the Windows vs. Linux performance for Intel's Alder Lake hybrid processors due to a number of readers inquiring how the OS support has evolved. In the process of carrying out those tests I also ran some fresh Windows vs. Linux tests with the AMD Radeon RX 6800 XT for how the OpenGL and Vulkan driver performance stands...
