[Qemu-devel] [PATCH RFC 0/4] vGICv3 support

[Pavel Fedin]

 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.

Pavel Fedin (4):
  Add virt-v3 machine that uses GIC-500
  Set kernel_irqchip_type for other ARM boards which use GIC
  First bits of vGICv3 support:
  Initial implementation of vGICv3.
