Linux 6.6 is set to be released as stable this weekend unless Linus Torvalds has reservations and decides to extend the cycle by one week. In any case there are some last minute fixes heading in to fix-up nine different Lenovo laptops with AMD Ryzen SoCs to make the hardware more usable under Linux...

Back in August Google Cloud announced the C3D instances powered by AMD EPYC 9004 "Genoa" processors while only last week was C3D promoted to general availability. Curious about the performance of C3D after being impressed by AMD EPYC Genoa bare-metal server performance at Phoronix as well as what I've seen with Genoa in the cloud at Microsoft Azure and Amazon EC2 / AWS, here are some benchmarks of the new C3D up against other GCE instances.

The Ubuntu 24.04 codename has been revealed as "Noble Numbat" while kicking off this next development cycle that is all the more exciting due to being the next long-term support (LTS) release...

Earlier this month Framework 13 began shipping out their AMD Ryzen powered modular laptop. Unfortunately though the launch-day testing of the Framework laptop under Linux was hampered by a BIOS issue. It's taken longer, but this week a new BIOS is now available for testing that resolves the AMD Linux graphics issue. Here's how to go about easily flashing the system BIOS with Fwupd and LVFS to get up and running well on Linux...

With the newly-started Mesa 24.0 development cycle a very exciting feature landed today... The ACO compiler integration for the RadeonSI Gallium3D driver has appeared to effectively wrap up for optionally making use of this Valve-developed shader compiler as an alternative to the AMDGPU LLVM shader back-end...

Tucked away within the October 2023 monthly status updates for the Linux Mint project is word they have begun working on their Wayland support...

Given the recent launch of the Intel Arc Graphics A580 for under $200, I've been working on a fresh round of Intel / AMD Radeon / NVIDIA GeForce Linux gaming/graphics and compute benchmark results. Next week that fresh arsenal of Linux graphics benchmarks on the very latest drivers will be published but for today is a look at the most surprising aspect: the OpenCL-focused GPU compute benchmarks.

The Servo open-source web browser engine continues progressing as a community project under the leadership of Linux Foundation Europe. Over the course of October more features were implemented and additional fixes merged...

Fedora 39 failed to make its "early" release target date, it didn't meet its otherwise targeted release date one week later, and is now facing another possible setback still. These release delays have been due to outstanding blocker bugs all related to the Raspberry Pi...

With the new AMD Ryzen 7 PRO 7840U Zen 4 mobile processor powering the likes of the Lenovo ThinkPad P14s Gen 4, I was curious about the performance impact of employing full disk encryption. Here are some benchmarks looking at the performance cost to enabling full disk encryption versus not utilizing any disk encryption while running Fedora Workstation on the new ThinkPad P14s Gen 4 AMD laptop.

Building off the recent release of OSPRay 3.0 with initial GPU acceleration support, OSPRay Studio has now been updated against this new version. As a reminder, OSPRay Studio is Intel's open-source interactive visualization and ray-tracing application...

There were many interesting talks last week at XDC 2023 in Spain around Rusticl, the open-source NVIDIA Vulkan driver, the Raspberry Pi graphics driver, RADV ray-tracing, AMD color management and HDR with the Steam Deck / Gamescope, and others. One of the other talks many Phoronix readers are likely to be interested in is around the state of the Wine Wayland driver...

Red Hat engineers continue working on Stratis Storage as a modern Linux storage solution that leverages the Rust programming language and built atop the proven XFS file-system and LVM. Stratis continues to strive for ZFS and Btrfs like functionality although its use in the wild still seems rather limited...

The X.Org Server and XWayland saw new point releases today as a result of three more security vulnerabilities being disclosed...

Most Linux desktop users/gamers/enthusiasts are relying on XWayland for X11 client compatibility atop Wayland compositors in the "rootless" mode. With the XWayland rootless mode, X11 applications and games can integrate nicely within a Wayland desktop environment with just the individual client window presented. However, for those interested, the XWayland "rootful" mode has become more capable this year for those wanting to render an entire X11 environment within the Wayland compositor as a window...

Since AMD's acquisition of Xilinx and working to broaden the portfolio of offerings for the data center, more AMD-Xilinx drivers have been working their way toward the mainline Linux kernel. There's been upstreaming efforts such as the Versal EDAC driver, generating DeviceTree nodes for PCI devices, Versal watchdog driver, QDMA driver, CDX bus support, and more. The latest driver working its way toward the mainline kernel from AMD is the AXI 1-wire driver...

The VKMS driver as a virtual kernel mode-setting solution as a software-only implementation of KMS for use with primarily headless Linux systems continues tacking on more features. Maira Canal and Melissa Wen presented last week at XDC 2023 on the VKMS driver that continues proving very useful for headless platforms as well as for testing purposes...

As yet another open-source Radeon Linux graphics driver change ahead of the upcoming Mesa 23.3 code branching and feature freeze is Vulkan VK_KHR_cooperative_matrix support with the RADV driver for RDNA3 hardware and newer using the GPU's Wavefront Mixed-precision Multiply Accumulate (WMMA) functionality...

As we approach the end of 2023, sadly, the real-time kernel "PREEMPT_RT" support still hasn't been mainlined... The main blocker pending is still the ongoing work around non-blocking consoles / threaded console handling to then allow the few dozen remaining out-of-tree RT kernel patches to be merged. The good news is that when the PREEMPT_RT support is ready for mainline, it looks like the RISC-V architecture support will also be real-time friendly too...

AMD's RadeonSI Gallium3D driver has been around for a decade since the Radeon HD 7000 "Southern Islands" graphics card days while finally the OpenGL renderer string is being changed to reflect "RadeonSI" as the name of the driver in use...

Ahead of the official planned announcement for Tuesday, the Mozilla Firefox 119.0 release binaries have been published for this monthly feature update...

While the recently released Ubuntu 23.10 is bringing some performance improvements to Intel Xeon Max / Sapphire Rapids, Ubuntu Linux still isn't delivering the best possible out-of-the-box server performance. For that Intel continues to show the importance of software optimizations with the likes of their in-house Clear Linux platform as well as the likes of CentOS Stream having more sensible defaults. Here is a look at the Intel Xeon Max 9480 performance across Ubuntu 22.04 LTS, Ubuntu 23.10, CentOS Stream 9, Fedora Server 39, and Clear Linux 40130.

While most hardware vendors are relying on LLVM when it comes to offloading compute work to GPUs, AI accelerators, FPGAs, and similar heterogeneous compute environments, right now each vendor is basically creating their own LLVM offloading run-time among a lot of other duplicated -- and often downstream only -- code. The new "llvm/offload" project hopes to lead to better collaboration in this area...

Following an FCV optimization for the latest Intel graphics hardware, ASTC LDR emulation, some still-pending Vulkan sparse support for ANV atop the existing i915 driver, and other recent Intel open-source "ANV" Vulkan driver optimizations, another optimization was just merged into Mesa 23.3...

The Etnaviv Gallium3D driver within Mesa has long been focused on reverse engineering and supporting Vivante graphics IP found in various SoCs.
