The usefulness of this configurarion is extremely doubtful, but let's fix it anyway (until we decide that we'll always support a VGIC).

KVM: arm-vgic: Set base addr through device API 2013-12-21T18:01:22+00:00 Christoffer Dall christoffer.dall@linaro.org 2013-09-23T21:55:56+00:00 ce01e4e8874d410738f4b4733b26642d6611a331 Support setting the distributor and cpu interface base addresses in the VM physical address space through the KVM_{SET,GET}_DEVICE_ATTR API in addition to the ARM specific API. This has the added benefit of being able to share more code in user space and do things in a uniform manner. Also deprecate the older API at the same time, but backwards compatibility will be maintained.

ARM: KVM: move GIC/timer code to a common location 2013-05-19T12:13:08+00:00 Marc Zyngier marc.zyngier@arm.com 2013-05-14T13:31:01+00:00 7275acdfe29ba03ad2f6e150386900c4e2d43fb1 As KVM/arm64 is looming on the horizon, it makes sense to move some of the common code to a single location in order to reduce duplication. The code could live anywhere. Actually, most of KVM is already built with a bunch of ugly ../../.. hacks in the various Makefiles, so we're not exactly talking about style here. But maybe it is time to start moving into a less ugly direction. The include files must be in a "public" location, as they are accessed from non-KVM files (arch/arm/kernel/asm-offsets.c). For this purpose, introduce two new locations: - virt/kvm/arm/ : x86 and ia64 already share the ioapic code in virt/kvm, so this could be seen as a (very ugly) precedent. - include/kvm/ : there is already an include/xen, and while the intent is slightly different, this seems as good a location as any Eventually, we should probably have independant Makefiles at every levels (just like everywhere else in the kernel), but this is just the first step.
