The biggest surprise this week so far with the Linux 6.7 merge window has been the landing of the Bcachefs file-system. Here is an early look at Bcachefs with Linux 6.7 and some preliminary benchmarks.

As with each kernel cycle, the networking subsystem updates for Linux 6.7 are heavy with a wide assortment of core networking infrastructure improvements, (e)BPF features continue to be tacked on, and new wired and wireless network hardware is supported...

The AppArmor Linux security system has picked up a few improvements and new features with the in-development Linux 6.7 kernel...

One of the great open-source achievements for 2023 was DreamWorks Animation open-sourcing their MoonRay renderer as the OpenMoonRay project. Since then DreamWorks along with other open-source stakeholders have continued advancing this open-source renderer and today marks the release of OpenMoonRay 1.4...

Landlock was merged back in 2021 with Linux 5.13 for unprivileged application sandboxing. Landlock is focused on restricting ambient rights and is implemented as a stackable Linux security module (LSM). With Linux 6.7 the Landlock LSM is now moving beyond just file-system access controls to also introduce initial networking support...

While confidential computing is a hot area right now, there's been a limited amount of cross-vendor cooperation with AMD having their own route with Secure Encrypted Virtualization (SEV) and Intel designing the Trusted Domain Extensions (TDX) that is still available in limited form. As one improvement coming with Linux 6.7, "configfs-tsm" has been submitted for pulling as a cross-vendor solution for confidential computing attestation reports...

Following some release delays the past few weeks, it's been decided today that Fedora Linux 39 is now ready to ship next week...

One of the last major blockers before the remaining real-time "PREEMPT_RT" patches can be upstreamed is sorting out threaded / atomic console printing. With the in-development Linux 6.7 kernel, there's been more work upstreamed in that endeavor...

Last week with the AMDVLK 2023.Q4.1 driver, AMD removed support for Polaris and Vega GPUs from this official open-source Vulkan driver. But as mentioned this doesn't impact the Mesa RADV Vulkan driver maintained by Valve, Red Hat, and other open-source developers. In fact, this week another optimization for Vega/GFX9 was merged for Mesa 24.0-devel...

Following Red Hat's decision to limit access to the RHEL source code to their customers, various RHEL-based Linux distributions were caught in a tailspin. CIQ (Rocky Linux), SUSE, and Oracle decided to form the Open Enterprise Linux association (OpenELA) to collaborate around the development of distributions with compatibility against Red Hat Enterprise Linux and ensuring open and free access to EL source code. Today they are announcing initial source available for their EL8 and EL9 packages...

We've been impressed with AMD Zen 4C cores with their initial appearance in Bergamo with the flagship EPYC 9754 and then over the summer with Siena for the likes of the EPYC 8324P(N) plus the EPYC 8354P(N) review soon. Today AMD is confirming what many had anticipated: Zen 4C cores will be coming to new Ryzen laptop SoCs.

OpenRazer as the community-driven, open-source project providing driver support for Razer peripherals on Linux is out with a new feature release...

Since Linux 6.6 we've been seeing work upstreamed for sysctl working to remove its sentinel, the final empty element on each sysctl array. This will cut-down on around 64 bytes of bloat per array, help with kernel build times, and an all-around improvement. With Linux 6.7 more of the sysctl changes are ready and hopefully for the v6.8 kernel cycle next year the effort will be completed...

Eric Engestrom has put out another on-time Mesa release candidate for what's culminating with the Mesa 23.3 release in the coming weeks...

Here is a look back at the most popular open-source and Linux news and featured articles/reviews for the month prior...

All of the power management related updates have been merged for the in-development Linux 6.7 kernel...

Earlier this month Intel introduced the 14th Gen Core "Raptor Lake Refresh" processors led by the flagship Core i9 14900K. Unfortunately my review samples had arrived late but in any event today are the first Linux benchmarks of the new Core i5 14600K and Core i9 14900K processors compared to prior 13th Gen Core processors as well as the AMD Ryzen 7000 series competition. All of these Intel and AMD processors were freshly re-tested on the newly-launched Ubuntu 23.10 with the Linux 6.5 kernel.

Earlier this year Intel published x86-simd-sort as a very speedy sorting library that initially leveraged AVX-512 instructions for 10x to 17x faster sorts. Numpy was one of the first major projects to adopt x86-simd-sort and OpenJDK more recently adopted it. Since the initial release we've seen more features and performance optimizations added. Today marks the release of x86-simd-sort 4.0 and it's delivering even greater performance while also adding an AVX2 code path to help those without AVX-512...

Sent out this morning was the Direct Rendering Manager (DRM) feature pull request of updated graphics/display drivers for the in-development Linux 6.7 kernel. Notable this round is Intel Meteor Lake integrated graphics now being considered stable / enabled out-of-the-box, Intel Lunar Lake graphics support has started to get underway, and AMD continues working on their upcoming hardware platforms...

The GCC 14 compiler has merged support for the Zhaoxin Yongfeng processors via the new -march=yongfeng and -mtune=yongfeng compiler options...

Merged one year ago was the initial Rust code for the Linux kernel back in Linux 6.1. We're now up to the Linux 6.7 development cycle and the enabling of more kernel functionality so it can be used/accessed from Rust code remains ongoing along with continuing to bump the base toolchain requirements and other functionality to make it more practical to write future Linux device drivers within this memory safe programming language...

While the original AMD Navi GPUs featured Next-Gen Geometry (NGG) support, it was borked for some GPUs and initially didn't work out quite as well as planned for vertex and geometry processing. The Mesa Radeon Vulkan driver "RADV" has worked on the NGG code for years and with RDNA3 GPUs it's finally been working out very well from the start and better than their legacy pipeline. All the while the RDNA1/RDNA2 experimental NGG stream-out support has continued to exist but hidden behind a feature/debug flag. That code is now being removed...

GhostBSD 23.10.1 released this weekend as the newest version of this FreeBSD-based desktop-focused operating system that employs the GNOME2-forked MATE desktop by default...

Guenter Roeck today sent out the hardware monitoring "HWMON" subsystem updates for the Linux 6.7 merge window...

Another merge window, another attempt for Bcachefs to be mainlined. This file-system was submitted again today for the now-open Linux 6.7 merge window and it stands better chances this cycle of being upstreamed...

Following the Linux 6.6 release, the GNU FSFLA folks are out with their GNU Linux-libre 6.6 downstream that strips out support for proprietary kernel modules, code considered non-free, and other de-blobbing activities in the name of software freedom...

Linux's FSCRYPT file-system encryption framework allows for native file encryption support on the likes of EXT4, F2FS, and UBIFS. FSCRYPT can make use of inline encryption hardware for accelerating the file-system encryption support and with the Linux 6.7 kernel will work for more scenarios...
