For years Intel has been developing the Low Power Mode Daemon "LPMD" to help their hybrid laptop and desktop CPUs deliver optimal power efficiency under Linux. Intel LPMD leverages hardware hints and other features for optimizing active idle power of the processor and putting the system into lower power modes where possible. This tool could soon call the Linux kernel source tree its new home.

Since its inception this user-space LPMD daemon has been developed by Intel engineers on GitHub. It's worked out well and back in November celebrated the

The open-source Haiku operating system inspired by BeOS is now seeing multi-core symmetric multi-processing (SMP) support on ARM64 that works at least in a virtualized world. Plus an assortment of other improvements made to this open-source OS over the course of April.

Overnight the Haiku project published their April 2026 status report. Some of the highlights for the past month include:

Haiku in April saw more work on its Bluetooth implementation, MMC/SHDCI device work around powering off when

The open-source Radeon "R300g" driver living within the Mesa codebase for supporting the aging ATI (AMD) Radeon 9500 "R300" through Radeon X1000 "R500" series graphics processors is going through a big code restructuring as part of a big undertaking in 2026... Yes, 24 years after the ATI R300 GPUs first released, thanks to a devoted open-source developer fan,

Quietly sneaking out at the end of last week was Vulkan 1.4.351 as the newest spec update to this high performance graphics and compute API.

Along with last week bringing the OpenCL 3.1 release and Vulkan SC SDK , The Khronos Group rounded out the week with Vulkan 1.4.351. This new Vulkan spec update ushers in six new extensions. New extensions include VK_KHR_opacity_micromap, VK_EXT_shader_split_barrier, VK_AMD

At the beginning of the month was the surprise milestone of AMD posting AMDGPU kernel driver patches for HDMI 2.1 Fixed Rate Link (FRL) support . The HDMI FRL patches have since been updated to also enable HDMI 2.1's Display Stream Compression (DSC) functionality for higher resolutions and higher refresh rates with the open-source AMDGPU driver.

Display Stream Compression with HDMI 2.1+ allows for higher refresh rates and resolutions like 4K@240Hz and 8K@120

GNOME's help viewer, Yelp, last year was impacted by a serious security issue for arbitrary file reads . There's a new vulnerability affecting the GNOME help viewer that led to the Yelp 49.1 release to address a possible Flatpak sandbox escape vector.

Thanks to funding provided by Germany's Sovereign Tech Agency with its Sovereign Tech Resilience program, Codean Labs was performing a security audit of Flatpak and various GNOME projects. In turn a significant Flatpak sandbox escape was discovered, related to last year's

The Intel Graphics Compiler "IGC" 2.34.4 release is out today as this compiler used by the Intel Compute Runtime for Level Zero and OpenCL compute on Intel graphics hardware plus is also used as the graphics shader compiler under Windows.

The IGC 2.34.4 release has more enablement work around the Crescent Island accelerator as well as Xe3P graphics at large. IGC 2.34.4 also adds support for WideMulMad , code scheduling improvements , Panther Lake optimizations, enabling the 2

Introduced in Linux 7.0 was FSERROR as generic I/O error reporting infrastructure . Linux to that point had no standardized mechanism for reporting metadata corruption or file I/O errors to user-space with each file-system doing its own thing. The Flash-Friendly File-System (F2FS) is now the latest Linux file-system preparing for FSERROR usage.

Via the F2FS development "dev" branch is support for reporting F2FS errors to FSERROR. Integrating FSERROR into F2
