[Qemu-devel] [RFC v4 0/8] QEMU: Support KVM on ARM

[Peter Maydell]

Round 4 of the QEMU patches to support KVM for
ARM on Cortex-A15 hardware. It's intended for use with
the kernel tree at
 git://github.com/virtualopensystems/linux-kvm-arm.git kvm-arm-v14-vgic-timers

Still RFC pending the kernel patches actually being accepted
upstream...

Changes v3 to v4:
 * minor updates to match kernel ABI changes (ID field in
   kvm_device_address is now 64 bits, core register offsets now
   changed due to use of pt_regs struct)
 * squashed the two 'update kernel headers' patches, since the
   plan is for vgic support to go upstream at the same time as
   the baseline kernel patchset
 * added a new patch 8 which adds ARM to the list of Linux archs
   which prefer 2MB alignment so they can use transparent hugepages

Changes v2 to v3:
 * applied various minor tweaks suggested during review of v2
 * rebased on master, resynced with kernel headers for v13
 * new patch 6 which uses a MemoryListener to track where the
   VGIC memory regions are mapped, so we can tell the kernel
   where they live in the memory map (via new ioctl
   KVM_SET_DEVICE_ADDRESS)
