ASTC Texture Compression License Turns Out To Be Restrictive Outside Of Khronos APIs
The lossy ASTC texture compression algorithm has been widely adopted in recent years with it being official extensions to both OpenGL and OpenGL ES. While it may not be as messy as the S3TC patent situation of the past, it turns out Arm's license on Adaptive Scalable Texture Compression actually is quite restrictive outside of the context of Khronos' APIs.

RADV Vulkan Driver Picks Up Several GFX10/Navi Fixes, Including To Address Random Hangs
If you are a user of AMD Radeon RX 5700 "Navi" graphics and don't mind riding Mesa Git, the latest 19.3-devel code as of yesterday has several more GFX10 fixes/improvements.
Perhaps most notable is this possible fix with random hangs no longer happening on Navi GPUs. But Valve's Samuel Pitoiset isn't too sure if the code in question fixed the issue, just that random hangs no longer happen now with RADV on these newest Radeon graphics cards.

AMDGPU Submits LRU Bulk Moves Support As A Linux 5.4 "Fix" For Better Performance
While initially queued as a work-in-progress feature for Linux 5.5, AMD has now submitted a batch of "fixes" to the current Linux 5.4 cycle that include enabling of the LRU bulk moves performance-boosting functionality.
Just last week that revert / enabling of LRU bulk moves for AMDGPU was queued in the 5.5 "WIP" branch while on Wednesday it was mailed in as part of the "fixes" targeting the current Linux 5.4 cycle now past its merge window. LRU bulk moves can yield some measurable performance wins for multiple types of workloads but was disabled previously over bugs that were corrected back in Linux 5.0 but then seemingly lost track of with the feature only coming up for re-enabling as of this summer.

Igalia Is Working On "mediump" Support For Mesa To Help With OpenGL ES Performance
Igalia is working on supporting OpenGL ES' GLSL marking of variables as "mediump" when the precision involving those variables can be lowered to half-float 16-bit registers. That in turn can help with performance when honoring that precision marking, which to date Mesa has ignored.
It turns out Igalia has been working on that Mediump support for Mesa's OpenGL ES with a focus on the Freedreno Gallium3D driver. Interestingly, it's under contract for Google -- they sure are ramping up their work on this open-source Qualcomm Adreno driver. Besides employing developers like Freedreno founder Rob Clark and former Broadcom VC4/V3D developer Eric Anholt, they are also contracting Igalia as part of the Freedreno effort.

Samsung, Red Hat to Work on Linux Drivers for Future Tech
The 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.
