Warp Pipe: Library for Simulation-Driven Development of PCIe Devices...
summary
Warp Pipe is an Apache-licensed C library that models PCIe as a packetized network at instruction‑level speed while preserving DLLP and TLP behavior, using Unix sockets to connect QEMU, Renode or native Linux/Zephyr nodes. It includes DLLP and TLP packetization, a Wireshark dissector for live packet inspection, Twister test integration to run multi-process host+device tests, example flows for DMA and a memory-mode BAR device, performance tuning with ~85% test coverage, and adapters for swapping simulated and real endpoints.
