Hi all, This is the remaining series for the full functional "dynamic node programming using overlay dtbo" feature. The first part [1] has already been merged.
Quoting from the original series, the first part has already made Xen aware of new device tree node which means updating the dt_host with overlay node information, and in this series, the goal is to map IRQ and IOMMU during runtime, where we will do the actual IOMMU and IRQ mapping and unmapping to a running domain. Also, documentation of the "dynamic node programming using overlay dtbo" feature is added. Patch 1 and 2 are fixes of the existing code which is noticed during my local tests, details please see the commit message. Gitlab CI for this series can be found in [2].
