Zink GL-On-Vulkan Driver Approaching OpenGL 3.1 Support
Zink is the generic OpenGL over Vulkan driver that has been in development as part of Mesa's Gallium3D code. It was just earlier this month that Zink achieved OpenGL 3.0 support and now it looks like OpenGL 3.1 will soon be flipped on.
Thanks to relying upon Gallium3D, Zink has already much of OpenGL 3.1 support in place for a while but has been blocked by NV_primitive_restart and ARB_uniform_buffer_object. These remaining extensions should be wrapped up soon.

Opengl 3.1
Not really, but I didn’t get around to blogging on Friday because I was working until pretty late on something that’s Kind Of A Big Deal.
Not really, but it’s probably more interesting than my posts about unhandled ALUs.

AMD Publishes AMDGPU UVD Firmware For Southern Islands
Recently AMD posted UVD video decode support for GCN 1.0 with the AMDGPU driver, one of the long holdouts for letting the AMDGPU DRM driver approach feature parity with the longstanding Radeon DRM driver that is the default for GCN 1.0/1.1 era GPUs. That AMDGPU UVD GCN 1.0 decode support is going into the Linux 5.9 kernel later this summer after years ago Radeon driver developers largely dismissed the efforts of porting the UVD decode capability for these original GCN graphics cards over to AMDGPU.
One of the reasons that this wasn't possible previously was AMD hadn't published the necessary firmware binaries for GCN 1.0 UVD that were compatible with the AMDGPU driver and just for the older Radeon DRM driver. But hitting linux-firmware.git today are those firmware files.

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. |
