Red Hat engineers have been developing Nova as a new, Rust-written open-source NVIDIA kernel graphics driver as the eventual successor to the Nouveau kernel driver and is designed around NVIDIA's GPU System Processor (GSP) thus making the driver relevant for RTX 20 / Turing GPUs and newer. Today they posted a request for comments (RFC) patch series of the Nova driver and Rust DRM abstractions.

Intel previously indicated that Lunar Lake processors would launch by the end of 2024 and leading to anticipation of a Q4 launch... Intel today announced that Lunar Lake will actually launch in Q3.

The x86 platform driver updates have been merged for the ongoing Linux 6.10 merge window. The platform-drivers-x86 changes continue to primarily revolve around x86 Intel/AMD laptops but also some other desktop/platform drivers. Now in Linux 6.10 there is also a new "ARM64" sub-section of the platform drivers.

The Fedora Engineering and Steering Committee (FESCo) has approved of the newest Fedora desktop ISO spin: Fedora Miracle.

Last week I wrote about Intel aiming to remove Xeon Phi support in GCC 15 with the products being end-of-life and deprecated in GCC 14. While some openly wondered whether the open-source community would allow it given the Xeon Phi accelerators were available to buy just a few years ago and at some very low prices going back years so some potentially finding use still out of them especially during this AI boom (and still readily available to buy used for around ~$50 USD), today the Intel Xeon Phi support was indeed removed.

It was just earlier this month that AMD Linux kernel graphics driver patches appeared for introducing a new ISP hardware block for Image Signal Processing with new AMD APUs. Already the AMDGPU ISP firmware has appeared in linux-firmware.git indicating that this "ISP" block may be coming in hardware quite soon if not already quietly found within some products.

It's not often having anything to write about on the Oracle Cluster File-System v2 (OCFS2), but with Linux 6.10 it's seeing a rather significant performance optimization.

As a small information heads up, the Linux 6.10 kernel will print the number of populated memory slots at boot time to the kernel log as a little helper.

Released over a year ago was Golang 1.20 with support for Profile Guided Optimizations (PGO) and has since been improved with Go 1.21 for 2~7% faster Go binaries thanks to this optimization approach also found with other compilers. The engineers at Cloudflare have put out a blog post this week praising Go's PGO support and the CPU savings they are seeing as a result.

While EROFS is seeing Zstd support and Bcachefs is seeing performance optimizations with the in-development Linux 6.10 kernel, over on the mature EXT4 file-system side the changes are mostly small. There are some minor changes, more folio conversion work, and also adding support for the FS_IOC_GETFSSYSFSPATH ioctl that has been seeing some standardization and adoption by the common Linux file-systems.

A Linux patch has been posted for delivering a quirk so that the Bigscreen Beyond VR Headset can properly behave under Linux and in turn also jives with the likes of SteamVR.

Following last year's release of PipeWire 1.0 for managing audio and video streams on the Linux desktop and proving itself a capable replacement to PulseAudio and JACK, among other uses, PipeWire 1.2 is nearing release. Out today is the first release candidate of the upcoming PipeWire 1.2.

Coming as a surprise, longtime Linux developer Oded Gabbay announced he's left Intel / Habana Labs and is therefore stepping down from the maintainer role of the Linux kernel drivers for the Intel Xe DRM driver and more notably the Habana Labs accelerator driver that he's maintained from the start.

The open-source Mesa driver developers employed by Valve for working on the Linux graphics stack have begun preparing the RADV Vulkan driver and the ACO compiler back-end for the upcoming "GFX12" graphics IP for next-generation RDNA4.

Intel's Image Processing Unit (IPU) IP has been a cause for concern in recent years as the lack of proper upstream open-source driver support has led Linux users running into troubles making use of MIPI camera sensors on modern laptops. Finally with Linux 6.10 the Intel IPU6 driver is being upstreamed into the media subsystem.

While most of you have not thought about or used Firewire (IEEE-1394) in years, there still are some legacy digital video cameras and some professional audio devices relying on the interface. Last year saw a new Firewire maintainer step-up for the Linux kernel after the code had fallen dormant. The plans by that new maintainer, Takashi Sakamoto, are to maintain Linux's Firewire support through 2029. He's continuing to do a good job with the upcoming Linux 6.10 kernel bringing the latest batch of Firewire enhancements.

Besides Linus Torvalds examining various elements of code he's merging and build testing it on his AMD Ryzen Threadripper workstation and now also testing more on ARM64 with Ampere Altra, he does these days still believe in "dogfooding" and is in fact running the leading-edge Linux kernel code even during the merge window.

The Mesa 24.1 stable release is nearing while out today is the fourth weekly release candidate. While the Intel and AMD Radeon graphics driver changes typically dominate new Mesa releases, Mesa 24.1-rc4 is headlined by a big change for the NVK open-source NVIDIA Vulkan driver.

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.
