OpenChrome Still Aspiring For Open-Source VIA Graphics, But Not Going Mainline This Year
At the X.Org Developers Conference earlier this month Kevin Brace provided an update on the state of the OpenChrome project that he continues to single handedly push forward.
While it has been over a decade since VIA x86 graphics were remotely common, Brace continues working on the OpenChrome DRM driver as a learning instrument and a passion for old hardware -- he also has contributed maintenance patches to SiS, S3 Graphics, and other DDX drivers left unmaintained.

Google Plumbing The Linux Support For Privacy Screens On Intel Laptops
A number of recent laptops have begun appearing that offer support for built-in privacy screens with the press of a button. These privacy screens reduce much of the visible light when viewed at angles to try to block out the screen contents from anyone that may be sitting besides the user. Linux has finally begun seeing this support prepared.

Google's SwiftShader Is Becoming Conformant & Performant For Vulkan On CPUs
SwiftShader had traditionally been about OpenGL and Direct3D over CPUs as a fallback while in recent years Google has been focused on making it viable for Vulkan. Recently SwiftShader reached Vulkan 1.1 conformance, but besides being conformant to the standard it's also showing it has some CPU performance potential.
With Kazan (formerly known as Vulkan-CPU) not advancing too quickly, SwiftShader thanks to Google's resources is becoming quite competent for Vulkan atop CPUs. Google developer Nicolas Capens talked about SwiftShader in the context of Vulkan at this month's X.Org Developer's Conference in Montreal.

Intel 8K Display Support Should Be Working With Linux 5.4
On top of the many Linux 5.4 features we have been talking about so far, it turns out with this kernel update due out in November that 8K display support for Intel (Gen11 Icelake and newer) should be in order.
8K displays are quite rare with the likes of the Dell UltraSharp 32 8K monitor retailing for $3899 USD. These current class of 8K displays require dual DisplayPort connections to drive due to current bandwidth limitations.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
