This is my alternative to Ashok's vGICv3 patch (https://lists.gnu.org/archive/html/qemu-devel/2015-05/msg03021.html), which i am currently working on. It addresses vGIC capability verification issue (kvm_irqchip_create() / kvm_arch_irqchip_create()), as well as offers better code structure (v3 code separated from v2). This patchset applies on top of this: https://lists.gnu.org/archive/html/qemu-devel/2015-05/msg00943.html. Note that GIC type selection still relies on machine name (virt-v3 vs virt), and not on machine option. Since libvirt has recently introduced support for extra options, i have absolutely nothing against Ashok's approach. I just did not change this yet because it would affect my testing environment. The aim of this RFC is to focus on vGICv3 implementation and related changes. And yes, i agree that v2 and v3 now have some copypasted code, and this is TBD.
