From: Luc MICHEL <luc.michel@greensocs.com> This patch series add support for the virtualization extensions in the ARM GICv2 interrupt controller. The first two commits do some refactoring to prepare for the implementation. Commits 3 and 4 are the actual implementation. The last commit updates the ZynqMP implementation to support virtualization. The current state allows to boot Xen (tested with 4.8 and 4.10) with Linux Dom0 guest properly. I also tested in SMP. It does not work directly because Xen expects to find CPU IDs in the GIC ITARGETSR0 register. This behavior is not documented in the GICv2 specification, and is not implemented in QEMU. By hacking this register, I was able to get the whole thing to boot in SMP properly. This hack is not part of those patches though. I also tested migration, it works fine AFAIK. I had to add the HYP and SEC timers in the ARM CPU VMState though (Xen uses the HYP one) (not part of those patches). I want to thanks the Xilinx's QEMU team who sponsored this work for their collaboration.
