Progress of WrapDrive
summary
WrapDrive implements DMA mapping for accelerators in multiple processes and runs SVM without page fault on D06 board using new VFIO and IOMMU APIs based on Jean‑Philippe Brucker ARM RFC v3. Tests use the ZIP SoC accelerator and show measurable throughput gains versus single‑process access; synchronous and asynchronous modes, one‑ and three‑process runs, and page‑table handling are exercised. Next milestone is supporting device‑triggered SVM page faults with a high‑performance implementation.
