QEMU¶

Warp Pipe repository tracks a fork of QEMU that includes a hw/pci/warp_pipe.c device, an interface towards warp-pipe, loosely based on the hw/misc/edu.c educational PCI device.

The QEMU plugin for warp-pipe allows to create a PCIe device using QEMU command-line interface, like:

qemu-system-x86_64 -device warp-pipe,connect=127.0.0.1:2115

The above will launch a QEMU system emulation process with an extra PCIe device attached, backed by a remote Warp Pipe server.

Building QEMU¶

If you installed warp-pipe to a non-standard location, you need to set the PKG_CONFIG_PATH variable:

export PKG_CONFIG_PATH=path/to/install-dir/lib/pkgconfig

The following snippet will allow you to build warp-pipe QEMU fork:

# ensure submodules are updated
git submodule update --init --recursive
mkdir qemu/build
cd qemu/build
../configure --enable-warp-pipe --target-list=x86_64-softmmu
make -j$(nproc)
export QEMU_BIN_PATH=`pwd`
cd -
