Greg Kroah-Hartman on Sunday submitted all of the "char/misc" patches for the Linux 6.15 merge window for this random catch-all area of the kernel with small drivers and other random/obscure hardware support.

Cloud Hypervisor began as an open-source Intel software project more than a half-decade ago with an emphasis on security and cloud deployments while leveraging the Rust programming language. With time its scope has broadened a lot as has its industry adoption. With time it added ARM64 support and recruited AMD, Ampere Computing, Microsoft, and others as its supporters while being folded into the Linux Foundation. The latest expansion for the project is introducing experimental RISC-V 64-bit support.

Last week PostgreSQL merged support for IO_uring that can provide for "considerably faster" performance of this popular open-source database server. Over the weekend some additional improvements were merged to the asynchronous I/O "AIO" code to PostgreSQL, including introducing a new batch mode that can also provide a performance win.

The in-development Linux 6.15 kernel is continuing to enhance its support for MIPI's SoundWire specification for small audio peripherals with this two-pin, low-complexity audio interface.

All of the Rust programming language infrastructure updates for the Linux 6.15 kernel have now been submitted. In addition to a lot of technical Rust improvements for the Linux kernel, this cycle also marks the first time Rust Linux maintainer Miguel Ojeda has taken a pull request directly from another contributor as they prepare to work out sub-trees for the Rust ecosystem.

The Arch Linux powered CachyOS is out with its March 2025 update that delivers a number of new features for this OS that is popular with open-source enthusiasts and power users for its out-of-the-box performance optimizations and extensive tuning.

Google's Ozone Wayland support continues to improve for benefiting the Chrome/Chromium web browser. The newest addition merged this past week is support for the xdg-session-management protocol.

The watchdog subsystem changes have been submitted for the Linux 6.15 merge window that is now at the mid-way point.

IO_uring continues maturing while being one of the greatest innovations within the Linux kernel in the past number of years. With Linux 6.15, IO_uring is getting even more interesting with introducing network zero-copy receive support. With this new code a 200G link could be saturated off a single CPU core in a recent demonstration.

The first quarter of 2025 is already drawing to a close... It seemed like Q1'2025 flew by but when looking back at all the Mesa 3D graphics driver activity, there was a heck of a lot accomplished in this area of the open-source landscape. Open-source Vulkan drivers continued advancing feverishly, Mesa code continues to be adapted to new platforms from Windows to Haiku OS, and all the big vendors continue being involved in open-source GPU drivers in one form or another.

While the upstream MIPS architecture is at a dead-end due to RISC-V, the Linux kernel code for the MIPS CPU architecture continues to improve for all the existing MIPS-based platforms out there. With Linux 6.15 there is new work for enhancing the Mobileye EyeQ6 SoC support.

Shotcut 25.03 is now available for this open-source and cross-platform video editor built atop the MLT Multimedia Framework.

With the first quarter quickly drawing to a close, here's a look back at the most popular Intel Linux news of the quarter. There's been excitement with the Battlemage discrete graphics cards with their open-source driver, early work on Xe3 graphics, AVX10.2 dropping the optional 512-bit features to make it mandatory now (thankfully!), and a lot of exciting upstream Linux kernel improvements.

Samsung used to sell web cameras for their smart TVs for use with living room video chatting with the likes of Skype. Samsung no longer supports Skype on their TVs (goodbye Skype!) or these devices but if you happen to have one laying around or buy one used for cheap, it's now possible to use these Samsung TV cameras as a standard web camera under Linux.

All of the PCI subsystem feature updates have now been merged for the Linux 6.15 kernel cycle. This includes some new drivers from AMD and Intel-Altera as well as various other PCI changes.

Earlier this month brought the Theora 1.2 beta release coming 16 years after Theora's libtheora 1.0 release for this video codec designed by Xiph.Org for use with Ogg audio. Theora is derived from the now rather ancient VP3 video codec, but for those continuing to enjoy content in Theora format, today brings the version 1.2 library.

Within This Week in Plasma, KDE developer Nate Graham notes the great excitement in KDE bug fixing this week/ KDE developers have lowered their HI/VHI priority bug counts down to "their lowest numbers ever numbers" in addition to working on new Plasma 6.4 features over the past few days.

The Debian release team announced that the Debian 13 "Trixie" transition and toolchain freeze began on-schedule this month.

The big set of open-source graphics driver updates for Linux 6.15 have been merged but Linux creator Linus Torvalds isn't particularly happy with the pull request. In particular, he's unhappy with some new "hdrtest" testing code being built as part of full kernel builds and the "turds" it leaves behind and this code "needs to die" at least from the perspective of non-DRM driver developers.

While fresh off the GNOME 48 release, GNOME desktop developers aren't slowing down and there's been some interesting activity to report this week.
