You may recall that earlier this year X.Org/FreeDesktop.org may have to cut CI services for developers over the cloud expenses associated with that continuous integration service for the likes of Mesa, the X.Org Server, and other components. CI usage was leading to a lot of bandwidth consumption so much so that the X.Org Foundation is facing potential ~70k USD cloud costs this year largely from their continuous integration setup...

The "V3DV" Vulkan driver being developed by Igalia under contract with the Raspberry Pi Foundation has offered a status update on this official driver for the Raspberry Pi 4...

Back in March I benchmarked the Linux Kernel Runtime Guard (LKRG) as a means of achieving additional security safeguards for a ~5% performance hit. With LKRG 0.8 having been released a few days ago, here is a fresh look at the LKRG performance compared to the stock kernel on Ubuntu 20.04 LTS.

There is finally a new release out of The Dark Mod, the original total conversion mod for Doom 3 that transformed into its own standalone game powered by the open-source id Tech 4 engine. This remains the lone flagship example of the open-source id Tech 4 game engine in action by the community (besides the DHEWM3 / RBDOOM-3-BFG engine work) with ioDoom3 having never taken off like ioquake3...

Last month you may recall that the free software purists maintaining the GNU Linux-Libre kernel dropped the Intel "iGPU Leak" security fix for Ivybridge / Haswell as they considered the compiled shaders/kernels responsible for clearing those residual contexts to be binary blobs. A resolution is now pending for upstream...
