One of the capabilities of newer Intel Xeon Scalable processors is support for Trust Domain Extensions (TDX) as a way of providing for confidential virtual machines. Intel TDX allows for "isolation, confidentiality, and integrity at the VM level" which is good from the security perspective but the dependence on signed binaries is causing mixed feelings within the Fedora camp at the broader open-source community...

While Linux 6.10 is poised to merge the initial NTSYNC driver for a Windows NT Synchronization Primitive driver that can help with faster Windows gaming performance under Wine/Proton (Steam Play), the driver isn't complete. The initial patches have been in Greg Kroah-Hartman's char-misc-next branch for several weeks to expose the NTSYNC character device, it isn't the entire patch series. Greg has now marked the driver as "broken" for Linux 6.10...

Back in February I wrote about AMD having quietly funded the effort for a drop-in CUDA implementation for AMD GPUs built atop the ROCm library. This was an incarnation of ZLUDA that originally began as a CUDA implementation for Intel GPUs using oneAPI Level Zero. While AMD discontinued funding ZLUDA development earlier this year, this CUDA implementation for AMD GPUs is continuing to see some new code activity...

Systemd 256-rc2 is out this evening with a few more features and other fixes collected over the past several weeks...

Linux kernel and Git creator Linus Torvalds is known for his current use of an AMD Ryzen Threadripper workstation as his main system after years of using Intel hardware. The past few years he's also been doing more ARM64 testing now that he has an Apple MacBook using Apple Silicon that serves as a nice travel device and for routinely compiling new ARM64 Linux kernel builds. More recently, his ARM64 Linux testing has increased now that he has a more powerful AArch64 system to complement his collection of routine gear...

The Framework Laptops are some great systems with their upgradeable/modular design, friendly Linux support, both Intel and AMD options, the latest models making use of an open-source embedded controller, and nice build quality. The Framework Laptops have proven very popular with Linux/open-source enthusiasts but one of the recurring critiques has been the lack of Coreboot firmware support for these laptops as an alternative (or outright replacement) to the proprietary BIOS/firmware. As a promising avenue for the future, there is experimental work being done on getting Coreboot up and running with the Framework 13 laptop powered by the AMD Ryzen 7040 series...

Scaleway by way of their Scaleway Labs group recently launched the Elastic Metal RV1 (EM-RV1) as the world's first RISC-V servers available in the cloud. These RISC-V cloud servers are built around the T-Head 1520 SoC and are an interesting way to explore the RISC-V architecture and/or otherwise make use of RISC-V for CI/CD deployments or other testing purposes. In this article are some benchmarks showing the RISC-V EM-RV1 performance against Intel and AMD x86_64 Linux.

Back in late 2023 were Rust abstractions for the Linux kernel's Virtual File-System (VFS) code. Those patches by Microsoft engineer Wedson Almeida Filho have now seen a second iteration posted... In addition to various improvements to the Rust VFS bindings, the new patches bring a work-in-progress EXT2 Rust file-system driver...

Debian's APT packaging tool is working its way toward the big APT 3.0 release.

There's another Rust upgrade coming for the Linux 6.10 kernel to bump the Rust version baseline required for building the Rust in-tree kernel components. This raising of the baseline will continue until a suitable minimum version is achieved where official Rust compiler "just works" well with the Rust'ed kernel bits. The Rust upgrade in Linux 6.10 also does away with its in-tree "alloc" fork for big code savings and simplifying maintenance...

The various ARM SoC/platform pull requests were already merged today by Linus Torvalds for the in-development Linux 6.10 kernel...

The work written about one month ago on Phoronix for much faster AES-XTS on modern Intel/AMD CPUs for speeding up disk and file encryption by as much as 155% with AMD Zen 4 CPUs has been submitted for Linux 6.10! As expected, this work providing new AES-XTS implementations for modern x86_64 processors is going into Linux 6.10 as part of the crypto subsystem updates...

While the Raspberry Pi 5 debuted last September already, sadly the mainline Linux kernel still lacks support for booting this popular single board computer... The support on Raspberry Pi OS and other downstream distributions/kernels is good, but the mainline kernel support for the Raspberry Pi SBCs remains a sore spot for this popular ARM single board computer. SUSE engineers have been working on implementing minimal boot support for the Raspberry Pi 5 that will hopefully make it to the mainline kernel...

Barring any last minute reservations by Linus Torvalds, Linux 6.9 stable should release later today. In turn the Linux 6.10 merge window will then open for the next two weeks and already some early pull requests have been submitted for this next kernel version. Here is a look at some of what to expect with the Linux 6.10 kernel...

The recent AMD P-State Linux driver patches for heterogeneous core CPU topology, Fast CPPC, and Core Performance Boost haven't made it to the Linux power management's "-next" branch ahead of the imminent Linux 6.10 cycle. Thus it looks like those features won't be ready to make it for v6.10 unless by chance being deemed ready in the coming days and then sent in as part of a secondary set of merge window changes. However, some other AMD P-State fixes/improvements are queued up...

With the new Intel "Xe" Direct Rendering Manager kernel driver that's been in development one of the touted benefits of the clean sheet driver design is that it would enable using Intel discrete GPUs on non-x86 CPU architectures. The long-used "i915" DRM kernel graphics driver has many x86'isms in the code-base built up over the many years of Intel integrated graphics that were only ever found within their x86/x86_64 processors. But now in the era of Intel discrete graphics, there's been issues in trying to run Intel Arc Graphics on say ARM, POWER9, and RISC-V, among others. The experimental Intel Xe driver was recently successfully demonstrated in running on ARM using an Ampere Altra workstation...

Following all of the GFX12 code and related IP landing within the AMDGPU Linux kernel driver as well as the LLVM AMDGPU shader compiler back-end and other code in enabling the next-generation of AMD Radeon graphics, the RadeonSI OpenGL driver support for RDNA4 (GFX12) was merged this Sunday into Mesa...

Linux I/O expert and subsystem maintainer Jens Axboe has submitted all of the IO_uring feature updates ahead of the imminent Linux 6.10 merge window...

The Linux 6.9 kernel should debut as stable later today unless Linus Torvalds has second thoughts and decides to delay it by issuing a v6.9-rc8 kernel instead that would then push out the official release by an extra week. In any event, as a last-minute "x86/urgent" pull request is another Zen 5 PCI ID being added...

The ReactOS project has posted their latest newsletter that outlines progress made during the past two months.

While we are all waiting for the NVIDIA R555 series Linux driver beta that is expected to debut as soon as next week based on prior information with Wayland improvements (explicit sync) and more, with the NVIDIA R560 series Linux driver successor is a very interesting change: NVIDIA is planning on defaulting to using their open-source GPU kernel driver by default for GeForce RTX 2000 "Turing" GPUs and newer...

AMD last week sent out a set of patches to enhance the open-source FFmpeg multimedia library with integration around the AMD Advanced Media Framework (AMF). The AMF SDK allows for "optimal" access to AMD GPUs for multimedia processing but this patch series questioned the need in an era of Vulkan Video APIs beginning to see adoption...

Linux 6.10 is introducing support for Trusted Platform Module (TPM2) encryption and integrity protections to prevent active/passive interposers from compromising them. This follows a recent security demonstration of TPM key recovery from Microsoft Windows BitLocker being demonstrated. TPM sniffing attacks have also been demonstrated against Linux systems too, thus the additional protections be made with Linux 6.10 to better secure TPM2 modules...
