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.

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...

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...

As shown already the Lenovo ThinkPad P14s Gen 4 with AMD Ryzen 7 PRO 7840U works out well on Linux and is very speedy as shown with that prior benchmarking on Linux 6.3, but for those moving to Linux 6.5 or newer the performance and power efficiency is even better. Like for those moving to the newly-released Ubuntu 23.10 with Linux 6.5, there are some nice performance gains to find with this laptop -- similar to the experience seen with various AMD Ryzen desktops on the new kernel.
