The Intel engineers enabling next-generation Arrow Lake processors for Linux have largely been just adding new device IDs and other mostly minor changes over current Meteor Lake processors. It was that way too for Arrow Lake's integrated graphics with largely re-using existing Meteor Lake graphics support, but now it's come to light that select Arrow Lake SKUs will feature updated graphics IP...

Following Linus Torvalds' release of the Linux 6.7 kernel last night, the FSFLA folks have released GNU Linux-libre 6.7-gnu as their downstream that strips out non-free microcode/firmware blob support and removes other bits that are not deemed in the interest of free software...

As anticipated Linus Torvalds went ahead and just released the Linux 6.7 kernel as the first new version of 2024...

In recent days there have been leaks about an MSI "CLAW" gaming handheld device set to be announced this coming week at CES in Las Vegas. Making this gaming handheld device interesting is that unlike the Valve Steam Deck and ASUS ROG Ally or Legion Go, it's expected to be the first handheld featuring an Intel Meteor Lake SoC. In particular, the recently launched Intel Core Ultra 7 155H. For those curious about what the performance is likely to roughly be in comparison to the AMD Ryzen Z1 Extreme, here are some benchmarks looking at the performance of these competing SoCs.

Linux 6.7 should be released later today as the first stable kernel of 2024. In turn the Linux 6.8 merge window will then open tomorrow and run for the next two weeks.

One of the limitations of Google Chrome's Wayland support has been the Video Acceleration API (VA-API) not being supported for GPU-based video acceleration as it's directly targeted the libva-x11 library. But with code merged on Friday to Chromium, libva-drm is now used to allow for working VA-API acceleration on X11 or Wayland...

For the GNOME desktop among the technologies that will hopefully mature into good shape this year are high dynamic range (HDR) display support as well as variable refresh rate (VRR). When it comes to the VRR support there's been more Mutter progress made in this effort...

Given the pace of hardware support and improvements these days, it's rather sad Linux Mint 21.3 continues to default to the Linux 5.15 LTS kernel that is the non-HWE default of Ubuntu 22.04 LTS for which the operating system is based. But at least Linux Mint 21.3 EDGE ISOs are being rolled out to make Linux 6.2 easily available for those with newer hardware support requirements...

While years ago it was hard envisioning Microsoft contributing significantly to the Linux kernel or Mesa 3D graphics driver stack, maintaining its own in-house Linux distribution, or publishing so much open-source software, these days it's par for the course thanks to Windows Subsystem for Linux (WSL), Linux dominating Azure instances, etc. Over the course of 2023, Microsoft continued investing in various Linux/open-source efforts that benefit their cause...
