Your SOC currently works by fluke because the guest doesn't look at the last 4K of the GICC. If you're happy with it continuing to work by fluke you could make your device tree say it had a 64K GICV region with a 64K-aligned base. To make it work not by fluke but actually correctly requires Marc's patchset, at a minimum. thanks -- PMM -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
