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.

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...

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...

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...

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...

The big pull request was sent out today of the numerous Direct Rendering Manager (DRM) updates for the in-development Linux 6.15 kernel.

Set to be merged for the Linux 6.15 kernel is the very initial NOVA driver core code that will be incrementally built up over time in succeeding kernel versions. For Linux 6.15, this open-source NVIDIA kernel driver isn't of any use for end-users as it's just the very preliminary pieces to begin crafting the foundation for the driver that is leveraging the NVIDIA GSP found with Turing and newer hardware. In preparation for future kernel cycles, the NOVA skeleton driver pieces were posted for review yesterday to begin fleshing out more of the driver's design...
