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...

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.

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.

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...
