Libre-RISC-V 3D CPU/GPU Seeks Grants For Ambitious Expansion

The NLNet Foundation is a non-profit supporting privacy, security, and the "open internet". Now the open source Libre RISC-V hybrid CPU/GPU is applying for eight additional grants from the NLNet Foundation, according to this update from the project's Luke Kenneth Casson Leighton (Slashdot reader #517,947):Details on each Grant Application are on the newly-opened RISC-V Community Forum. The general idea is to kick RISC-V into a commercially-viable mass-volume high gear by putting forward funding proposals for NEON/SSE-style Video Acceleration to be upstreamed for use by ffmpeg, vlc, mplayer and gstreamer; hardware-assisted Mesa 3D (a port of the RADV Vulkan Driver to RISC-V), and a hardware-accelerated OpenCL port to RISC-V. This all in a "Hybrid" fashion (a la NEON/SSE) as opposed to the "usual" way that 3D and Video is done, which hugely complicate both software drivers and applications debugging. In addition, the Libre RISC-V SoC itself is applying for grants to do a gcc port supporting its Vectorisation Engine including auto-vectorisation, and, crucially, to do an entirely Libre-licensed ASIC Layout using LIP6.fr coriolis2, working in tandem with Chips4Makers to create a 180nm commercially-viable single-core dual-issue test ASIC. The process takes approximately 2-3 months for approval. Once accepted, anyone may be the direct (tax-deductible) recipient of NLNet donations, for sub-tasks completed. Worth noting: Puri.sm is sponsoring the project, and, given NLNet's Charitable Status, donations from Corporations (or individuals) are 100% tax-deductible.
