This is inspired from the work done by Oleksandr for the Disk device [1]. Great work! The first two patches can be applied right away, but the last two need Oleksandr's series [1] to be applied first. I have reviewed patches #3/4 and #4/4 (libxl_arm.c changes).FYI, I have recently pushed V8 of my series [1], which changes the code in libxl_arm.c a bit. This is developed as part of Linaro's Project Stratos, where we are working towards Hypervisor agnostic Rust based backend [2]. I must accept that I am a beginner to Xen and developed this patchset based on support for existing devices like Disk or Keyboard. There may be bits which I missed or the one I added which aren't really required.
