With Linux 6.11 support for the Lenovo Yoga Slim7x and ASUS Vivobook S15 are upstreamed for some of the first Qualcomm Snapdragon X1 Elite powered laptops. But for follow-on kernel cycles you can expect yet more Snapdragon X1 Elite/Plus powered laptop support to appear with new DeviceTree additions. On Friday, Linaro engineer Konrad Dybcio sent out the patches for enabling the X1 Elite powered Lenovo ThinkPad T14s Gen 6 laptop...

With Linux 6.11 over on the Arm-focused SoC side there were three new SoCs and 59 new machines/boards added for Arm and RISC-V. The MIPS pull request was submitted overnight for this next kernel version and there is just two new SoCs being introduced...

KDE developer Nate Graham is out with a summer time update that highlights the interesting improvements made to the KDE desktop and related apps over the past two weeks...

Eric Engestrom is once again serving as the Mesa release manager and today took to forking the Mesa 24.2 codebase followed by issuing the first release candidate...

Back in January AMD quietly posted an XDNA Linux kernel driver for enabling the Ryzen AI NPUs. The driver has been maintained within that GitHub repository since but without any clear effort for getting this accelerator driver reviewed and merged into the upstream Linux kernel. Today that first step is finally being taken with the Ryzen AI XDNA Linux kernel driver patches posted to the Linux kernel mailing list and dri-devel to begin facilitating the upstream review process for getting this AI accelerator driver in the mainline kernel...

Red Hat developer Karol Herbst continues improving the support for Rusticl, the Rust-based modern OpenCL implementation for Mesa's Gallium3D drivers...

All of the SoC and platform updates slated for the Linux 6.11 kernel have been merged including new SoCs and adding DeviceTree files for a number of new systems, including some of the first Qualcomm Snapdragon X1 powered laptops...

NVIDIA's EGL-Wayland library continues to be maintained as an EGLStream-based Wayland external platform library for client-side Wayland support to EGL atop EGLDevice/EGLStream...

Linux sound subsystem maintainer Takashi Iwai has sent out all of the sound driver patches for the in-development Linux 6.11 kernel...

Vulkan 1.3.291 was published this morning and with this specification update comes one prominent new extension: VK_AMD_anti_lag...

The SLAB pull request landed in Linux 6.11 Git on Thursday with kmem_buckets-based hardening of kernel memory allocations...

The Freedreno Gallium3D driver that started out a decade ago providing reverse-engineered, open-source 3D driver support for Qualcomm Adreno hardware has now enabled support for the X1-85 GPU that is found within the Snapdragon X1 Elite and Snapdragon X1 Plus laptop SoCs...

The Fedora change proposal was approved this week by their engineering and steering committee to support AMD SEV-SNP virtualization host support to allow easily launching confidential computing virtual machines (VMs) with Fedora 41...

Last week I published some initial benchmarks of the Amazon/AWS Graviton4 processors now available within the EC2 cloud using the new "R8g" instances. That initial comparison was a 64 vCPU comparison of Graviton4 against AMD EPYC and Intel Xeon 64 vCPU AWS instances. In today's article is a look at the 96-core Graviton4 bare metal performance using the "r8g.metal-24xl" AWS instance type. The Graviton4 r8g.metal-24xl performance was then compared in today's article against various bare metal AMD EPYC, Ampere Altra Max, and Intel Xeon processors in the lab at Phoronix.

It looks like the AMD RDNA4 "GFX12" graphics driver support is in good shape: AMD is now enabling the driver support for the next-generation graphics "out of the box" with the latest pending patches...

The Intel-initiated Sound Open Firmware project for open-source audio DSP firmware and related tooling is out with a new v2.10 release. SOF continues to be backed not only by Intel but also Google, AMD, Realtek, NXK, Mediatek, and other organizations...

Toward the end of 2022 a GCC AArch64 compiler change was quietly made by Arm that allows "-march=native" to be handled on 64-bit ARM by treating it as the equivalent "-mcpu=native" option. The change happened to fly under my radar at that time and didn't draw much attention at large while now it's finally being officially documented in hopes of similar behavior being adopted by other compilers for AArch64...

With the maturity of the EXT4 file-system it's not too often seeing any huge feature additions for this commonly used Linux file-system but there's still the occasional wild performance optimization to uncover... With Linux 6.11 the EXT4 file-system can see upwards of a 20% performance boost in some scenarios...
