PCIem: A Linux Framework for Virtual PCIe Device Emulation and Driver Development
By
71bw
A baker's-dozen of insight crammed into one ring.
Summary
PCIem is a Linux kernel framework that enables userspace-defined virtual PCIe device emulation, allowing developers to create synthetic PCIe cards that appear as legitimate PCI devices to the host operating system. The framework facilitates PCIe device driver development and testing without requiring actual hardware, providing a virtual environment for driver development. It's compared with libfvio-user as a different solution for different needs in the PCIe device emulation space.
Key quotes
· 3 pulledPCIem is a framework that creates virtual PCIe devices in the Linux kernel by leveraging a few novel techniques to populate synthetic cards as legitimate PCI devices to the host OS.
To brief what PCIem is: a framework for (Albeit not limited to) developing and testing PCIe device drivers without requiring actual hardware on the host.
PCIem and libfvio-user are two different solutions for different needs, there may be confusion when comparing both so
