Intel's IGC 1.0.4241 Graphics Compiler Adds DG1 Platform Support
Significant with this new version of the IGC compiler is the DG1 platform is supported, their first graphics card. IGC already supported Gen12/Xe while now the initial bits are in place for the forthcoming DG1 discrete graphics card. For weeks now we've been seeing Intel's many open-source developers posting new DG1 enablement patches from the Linux kernel through their Mesa stack to the media encode/decode driver and now working its way into DG1 for their compute stack. Obviously you also need to be running on the future Linux 5.9 kernel and more for getting this DG1 support all aligned but at least the IGC side work is now in place.

Wayland's Weston 9.0 Aims For Release In Early September
With Weston 8.0 having shipped in January, Wayland developers are beginning to prepare for the next feature release of this reference Wayland compositor.
Simon Ser has once again stepped up to take over Weston release management duties. He is planning to tag the Weston 9.0 Alpha at the end of June, a Weston 9.0 Beta in mid-August, and a first release candidate at the end of April. If all goes well he hopes to ship Weston 9.0 on 3 September but could be delayed by some days if additional release candidates are warranted.

LLVMpipe Gallium3D Driver Now Exposes OpenGL 4.0
The LLVMpipe Gallium3D driver that provides a software/CPU-based OpenGL implementation for running on systems as a fallback path when no GPU / hardware OpenGL driver is available, a vendor-neutral path for debug purposes, and similar use-cases, now has OpenGL 4.0 support.

NVIDIA Video Codec SDK 10 Brings Few Changes For This Proprietary Library
NVIDIA has quietly released Video Codec SDK 10 as the newest version of their proprietary video encode/decode implementation designed for their GPUs.
[...]
NVIDIA has already contributed to FFMpeg support for using the new NVENC presets, multi-pass encode modes, and low-delay key frame scaling for this video library as part of the Video Codec SDK 10 support. A follow-up commit added additional H.264 levels now supported.

RadeonSI Switches To Make Greater Wave64 Use On Navi
While RDNA/Navi brought Wave32 support, the open-source RadeonSI Gallium3D driver for Linux has decided to switch to make greater use now of Wave64 for more shaders.
[...]
The change to use Wave64 for more shader stages was merged this week for Mesa 20.2. The commit does add the new "nggctess" perf flag for always using NGG culling for tessellation, complementing the existing nggc (for always using NGG culling) and nonggc for disabling NGG culling.

Mike Blumenkrantz: Binding Locations
So let’s get down to pixels. The UBO indexing is now fixed-ish, which means moving onto the next step: setting up bindings for the UBOs.
A binding in this context is the numeric id assigned to a UBO for the purposes of accessing it from a shader, which also corresponds to the uniform block index. In mesa, this is the struct nir_variable::data.binding member of a UBO. A load_ubo instruction will take this value as its first parameter, which means there’s a need to ensure that everything matches up just right.

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. |
