[Qemu-devel] [PATCH 0/5] Extensible VCPU state IOCTL

[Jan Kiszka]

This series adds support for the upcoming new KVM IOCTL to get/set VPCU
states as a set up substates. See [1] for more details on this KVM
extension.

While I did not fully convert the corresponding qemu-kvm part (it is
expected to morph into upstream soon), QEMU should receive a complete
conversion. So this series first fixes, cleans up, and refactors some
KVM code, and then adds KVM_GET/SET_VCPU_STATE as an alternative to the
classic multi-IOCTL state getting and setting. I did this full
conversion with all its #ifdefs in order to be able to drop legacy
support at some (still distant) point in the future.

Along with the conversion a few fragile migration, save/restore and
reset cases are fixed. We now have access to all missing exception,
interrupt, and NMI states KVM kept private so far. See [2] for details.
