Hi all, This series adds I3C bus support to QEMU and adds more functionality to the Aspeed I3C controller.
This implementation is a basic implementation that introduces IBIs (including hot-join), CCCs, and SDR data transfer. As-is, it doesnt support multi-controller buses or HDR transfers. First we add the I3C bus and controller model. With that added we gradually extend the functionality of the Aspeed I3C controller so it can do transfers. With that added, we add 2 targets. The first target is a mock I3C target. It's intended to be a very simple target just to verify that I3C is working on the guest. Internally, we've used it on Linux to verify that i3C devices can be probed and can send/receive data and send IBIs. The second target is a remote target. The intention of this is to be able to communicate to a target that exists outside of QEMU. Lastly we add hotplugging support. The hotplugging doesn't do anything too complicated, it just adds the device attempting to hotplug to the bus. It is the device's responsibility to hot-join and go through the DAA process to participate on the bus. Thanks!
