[Qemu-devel] [PATCH 0/7] target-arm: Support AArch64 KVM

[Peter Maydell <peter.maydell@linaro.org>]

This patchset adds support for basic AArch64 KVM VM control.  It sits
on top of the mach-virt + cpu-host patchset I sent out last week. 
The core of these patches is the work done by Mian M. Hamayun; I've
just taken that, refactored it a bit to sit on top of the
mach-virt+cpu-host patchset instead af defining an 'a57' cpu, and
made some minor bugfixes as part of the code review I did in the
process.

(Mian: my apologies for not looking at your last patch series sooner. 
This actually ended up in my generating extra work for myself since
if I'd been a bit quicker about that we could have dealt with more of
this in code review rather than my fixing things up. I'll try to do
better next time around.)

This patch series supports:
 * 64 bit KVM VM control
 * SMP and UP
 * PSCI boot of secondary CPUs
It doesn't support:
 * migration
 * reset (partly because there's no way to reset a mach-virt system yet)
 * anything except "-cpu host"
 * debugging the VM via qemu gdbstub
 * running 32 bit VMs on a 64 bit system
   [Mian's patchset includes support for that but I have left it out
   for the moment because it needs more thought about UI and so on]

You can find this patchset plus the mach-virt/cpu-host one at
