Btrfs has long provided a built-in integrity checker tool into the file-system driver. However, slated for Linux 6.6 is deprecating of this integrity checker...

Ahead of the Linux 6.5-rc2 release tomorrow there was a set of x86/x86_64 kernel changes merged overnight to deal with some weaknesses in the kernel's Control Flow Integrity (kCFI) / FineIBT (Indirect Branch Tracking) code...

With all the news in recent weeks following Red Hat's decision to limit access to RHEL sources that in turn lead to changes for AlmaLinux, finding new ways to obtain sources at Rocky Linux, interesting statements from Oracle, and even SUSE forking RHEL. The public RHEL sources now will basically be the upstream CentOS Stream code for which future Red Hat Enterprise Linux versions are ultimately based. The CentOS Project issued a new statement on Friday...

Earlier this month brought the release of systemd 254-rc1 with a new soft-reboot mechanism, officially deprecating System V scripts, a new systemd-battery-check process that runs at boot to check any system battery level status, and various other changes. On Friday systemd 254-rc2 was released with a few more changes...

The uutils project continues advancing as a modern, drop-in replacement to the GNU Coreutils utilities that is written in the Rust programming language...

Imagination Technologies today published their fourth iteration of their in-development PowerVR DRM kernel graphics driver targeting their Rogue architecture and future graphics IP. This open-source kernel driver ultimately will go along with their PowerVR Vulkan driver they continue developing within the Mesa code-base...

While IO_uring has been one of the most interesting kernel innovations of recent years and can allow for great speed-ups to async I/O, there have been some security concerns and with the Linux 6.6 kernel it will be easier for Linux administrators to disable it system-wide if so desired...

AMD Linux engineers are working on extending the Direct Rendering Manager (DRM) subsystem used by their GPUs/accelerators to allow up to 128 DRM devices per system...

System76 developers working on their Rust-written COSMIC desktop have recently been improving a number of areas of this open-source desktop...

The GTK toolkit and GLib support for Apple's macOS may be taking a back-seat to other platforms moving forward and would fall into a "best effort" category...

Yesterday Intel engineers sent out early compiler patches for Lunar Lake and Arrow Lake with adding the new instructions of AVX-VNNI-INT16, SM3, SHA512, and SM4. Today that new instruction support was complemented by a new patch out of Intel for actually adding the new Lunar Lake, Arrow Lake, and Arrow Lake S targets to GCC...

Consulting firm 9elements sent out a set of patches this week to the peci-cputemp and dimmtemp drivers for supporting Intel Sapphire Rapids platforms, including for the up to eight socket configuration capable this generation...

Mesa's Rusticl OpenGL implementation written in Rust it turns out can already run the Tinygrad open-source software with its OpenCL back-end for running the LLaMA model...

With Red Hat now restricting access to the RHEL source repositories, AlmaLinux and other downstreams that have long provided "community" rebuilds of Red Hat Enterprise Linux with 1:1 compatibility to upstream RHEL have been left sorting out what to do...

Similar to what I have shown with the Ryzen 9 7950X AVX-512 desktop performance and AMD EPYC 9004 series AVX-512 server performance, the new Ryzen 7040 series mobile processors are exhibiting great AVX-512 performance for laptops. In today's article is a look at the performance impact when toggling AVX-512 capabilities for a Ryzen 7 7840U "Phoenix" SoC compared to toggling AVX-512 with prior Intel Tiger Lake and Ice Lake laptops that offer AVX-512.

Intel's Linux software engineers understand the annual GCC compiler release cadence well and acknowledge the importance of having tuned compiler support available at launch. Intel for years has tended to get their new CPU support and new ISA features upstreamed into GCC as well as LLVM/Clang well ahead of product launch so that by the time their new consumer and server CPUs are shipping, there tends to be support within compilers just not at their stable versions but already found in the likes of Ubuntu. With that said, today Intel engineers posted initial compiler patches for Lunar Lake and Arrow Lake processors...

While less than one week has passed since the Linux 6.5 merge window ended and 6.5-rc1 being issued, there is already the first set of drm-misc-next changes submitted to DRM-Next of early open-source graphics/display driver changes geared for Linux 6.6 later this year...

Mesa 23.2 feature development is now over with the code having been branched and the first release candidate tagged for what will be this quarter's stable release series...

Intel this morning released their open-source Compute Runtime 23.22.26516.18 as their newest monthly update to this open-source compute stack used on Linux for OpenCL and oneAPI Level Zero usage...

Last week we began seeing AMD engineers post Linux patches for "Family 26" (1Ah) CPU enablement that is more than likely for Zen 5 processors. This week the AMD "1Ah" work has carried forward with new patches having been merged into the Linux 6.5 kernel...
