For basic testing Ben's qemu branch should work for you. https://gitlab.com/bwidawsk/qemu/-/commits/cxl-2.0v4/ Note there are some big questions over the approach used for integrating this with the PCI subsystem (auxiliary bus vs library) which I'm not sure we've reached a conclusion on yet. One minor thing on the wish list is lspci support to at least identify the presence of a DOE. I have patches for that and will send out fairly soon once I've cleared a backlog of other stuff. My main focus right now is on resolving some of the opens around the QEMU support for CXL emul in general, but I haven't touched the DOE stuff beyond rebasing. *fingers crossed* I should have an updated qemu tree out sometime in next week or so. Thanks, Jonathan
