Most of the Mesa Radeon Vulkan "RADV" driver development has been done by the likes of Valve, Google, and Red Hat engineers with it being an "unofficial" driver while AMD supports AMDVLK as their official open-source Vulkan driver as well as supporting their closed-source AMDGPU-PRO Vulkan driver too that shares common code with their Windows Vulkan driver. It was pleasant to see AMD this week though submitting new feature code to RADV.

Google engineer Ilya Tocar has introduced the notion of "light" AVX support within the LLVM compiler infrastructure for utilizing some benefits of Advanced Vector Extensions (AVX) but trying to avoid the power/frequency impact that AVX-512 use has on older generations of Intel processors.

Hitting the linux-firmware.git tree this morning were new AMDGPU firmware files for IP blocks found on upcoming hardware. It's likely these new firmware files are for the forthcoming Ryzen 7040 series mobile processors with RDNA3 graphics.

Among the numerous exciting aspects of Intel's next-generation Meteor Lake client processors is the introduction of the Versatile Processing Unit (VPU) inference accelerator for Computer Vision (CV) and Deep Learning (DL) workloads.
