I've pushed to gitlab.com/jic23/qemu cxl-2024-04-22-draft Its extremely lightly tested so far. To save time, I've temporarily dropped the fm-api DCD initiate dynamic capacity add patch as that needs non trivial updates. I've not yet caught up with some other outstanding series, but I will almost certainly put them on top of DCD. Jonathan > > Jonathan > > > > > ~Gregory > >
