It's not entirely clear which of the various possible QEMU aarch64 setups you're interested in. Summary: (1) using QEMU on aarch64 hosts to emulate other CPU architectures (eg x86, MIPS): this went into QEMU about six months ago and was in the last release of QEMU (1.7) (2) using QEMU on aarch64 hosts as the userspace component of a VM using KVM kernel support to run an aarch64 guest: this should work with current QEMU, though some functionality (for instance, migration) is not yet implemented (3) using QEMU to emulate individual Linux AArch64 binaries, running on any host (typically x86): this works in current upstream master, but some instructions (parts of SIMD) are not yet implemented. I hope we'll get the SIMD coverage completed within the next few weeks, in time to put it into QEMU 2.0. (4) using QEMU to emulate an entire AArch64 system that can boot a guest kernel, typically running on an x86 host: we're working on this right now; we have work-in-progress code which will boot a kernel and are working on cleaning it up to upstream quality. I expect we'll have this done within a month or two, but it won't make it into the QEMU 2.0 release (slightly too late). I'm guessing you're interested in (2) or maybe (1). For (2), kvm...@lists.cs.columbia.edu is a good list to follow to monitor what's currently going on. thanks -- PMM
