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.

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…

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. Maíra 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…

While Meteor Lake isn’t shipping until December, Intel’s open-source Linux engineers for months have already been working on 15th Gen Arrow Lake (as well as Lunar Lake, among their other processor lines) for getting the driver support in order. The latest early hardware enablement to talk about is the initial Arrow Lake S support coming to their video acceleration drivers…
