NVIDIA sets RVA23, ACPI, PCIe coherency and peer-to-peer PCIe as its requirements for CUDA on RISC-V, and points at a SiFive demo
- Sources: primary, discussion
- Summary: At Hot Chips 2026 NVIDIA set out its host requirements for running CUDA on a RISC-V CPU: the RVA23 profile, ACPI, PCIe cache coherency and peer-to-peer PCIe. NVIDIA pointed at a SiFive-based demonstration as the current reference.
- Why it matters: The requirement list rules out effectively all existing RISC-V hardware, so CUDA on RISC-V arrives on server platforms rather than on the boards developers already own.
