There hasn't been much to report on lately for the reverse-engineered Nouveau driver providing open-source NVIDIA GPU driver support on Linux. Several recent Linux kernel series haven't even seen any Nouveau DRM/KMS driver pull requests with changes. For the upcoming Linux 5.20 cycle, a Nouveau set of changes were sent in today to DRM-Next but it's quite tiny...

Back in March when AMD Milan-X rolled out I published a number of EPYC 7773X benchmarks as well as Milan-X benchmarks in the cloud. Since then there have been new Linux kernel improvements and other changes in the ever-advancing open-source world. Plus simply more time to conduct additional tests over the summer. Here is the latest round of my AMD EPYC 7773X 1P and 2P benchmarking compared to the Milan EPYC 7713/7763 SKUs as well as Intel's Xeon Platinum 8380 "Ice Lake" competition.

While AMD's open-source Linux graphics driver stack is wonderful if living on the bleeding-edge with a modern Linux distribution, for those on enterprise Linux distributions that tend to stick to older versions of packages for the support lifetime or where wanting to run a vetted/qualified driver stack, it can be more of a pain. For AMD's packaged Linux driver stack it only supports those select enterprise Linux distributions and can run into pain points trying to run elsewhere or even say running brand new LTS distributions at times can lack support. There are also challenges in installing/running the ROCm compute stack outside of the few officially supported Linux distributions by AMD. Fortunately, they are now hiring Linux build engineer(s) to work on such issues...
The GCC Steering Committee has approved of the GCC Rust front-end providing Rust programming language support by the GNU Compiler Collection. This Rust front-end will likely be merged ahead of the GCC 13 release next year...
With the very popular HP Dev One that is powered by an AMD Ryzen 7 PRO SoC and running Pop!_OS, a number of Phoronix readers inquired about seeing benchmarks of some of the alternative kernel flavors on the device. So here is a look at the stock Linux 5.17 kernel up against the Linux 5.18 and 5.19 (Git) kernels and then Liquorix and XanMod tossed in as alternative flavors running on the Pop!_OS 22.04 installation.

Intel's open-source Compute Runtime for providing OpenCL and oneAPI Level Zero support on their graphics hardware appears to be in roughly good shape now for DG2/Alchemist based on external/independent monitoring of the effort...
The Linux kernel has long honored the "nordrand" kernel parameter to disable kernel use of the Intel RDRAND and RDSEED instructions if not trusting them -- either out of security concerns that they could be compromised by the vendor or running into hardware/firmware issues around RdRand usage. But the Linux kernel is preparing to drop that kernel parameter with users encouraged to use the more generic "random.trust_cpu" parameter...
Leah Rowe has announced the release of Libreboot 20220710, the downstream of Coreboot that takes a firm approach to ensure boot firmware freedom with avoiding proprietary blobs even when it means reduced hardware coverage/support. As such with avoiding the likes of the Intel FSP, the supported list of motherboards is quite limited...

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.
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...
