Hi Roman, Sorry for the late reply. In my series of patches I partially reuse Phillip Tennen's work that you have mentioned https://mail.gnu.org/archive/html/qemu-devel/2021-02/msg05874.html. The main idea and provided feature is the same, so please select the series on your choice. I just can say that I'm ready to update/improve my patches asap, make them ready to be merged. Can't say anything about Phillip, is he ready too or not.
