Tools: Linux Kernel Framework For Pcie Device Emulation, In Userspace
A Linux framework to enable userspace-defined "Virtual" PCIe card shims to enable in-host PCIe card driver development.
PCIem 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 developing and testing PCIe device drivers without requiring actual hardware.
The card is programmed entirely in QEMU, who does all the userspace initialization and command handling from the real driver running in the host. Can run software-rendered DOOM (Submits finished frames with DMA to the card which QEMU displays) and also simple OpenGL 1.X games (On the screenshots, tyr-glquake and xash3d; thanks to a custom OpenGL state machine implemented entirely in QEMU that software-renders the command lists and updates the internal state accordingly).
