on YouTube ↗33m

" summary

WarpDrive is a user‑space accelerator framework that bypasses kernel data paths with a kernel component and a user library, targets Hisilicon Kunpeng 920 and is on GitHub, and supports three modes: no IOMMU (physically contiguous DMA), IOMMU, and plans to adopt SVA shared virtual address for unified page tables. It exposes queue management with 1024 queues (one queue per process), supports SR‑IOV style 1 PF + 63 VFs, and shows 100–200x speedup versus CPU in vendor tests.
