Overview

ThreadSanitizer introduced the concept of software fibers as more fine-grained execution units. — Mapping High-Level Concurrency from OpenMP and MPI to ThreadSanitizer Fibers (2023)

We propose an optimization, Targeted VFIO Mapping, which leverages the insight that mapping only the bounce buffers to the IOMMU—rather than the entire guest memory—is sufficient to support functional and secure device passthrough, while greatly reducing start-up latency. — Optimizing Launch Latency for Confidential VMs with Device Passthrough in the Linux KVM Hypervisor (2026)
