Hi all,

as the list of yet user-unaccessible x86 states is a bit volatile ATM,
this is an attempt to collect the precise requirements for additional
state fields. Once everyone feels the list is complete, we can decide
how to partition it into one ore more substates for the new
KVM_GET/SET_VCPU_STATE interface.

What I read so far (or tried to patch already):

- nmi_masked
- nmi_pending
- nmi_injected
- kvm_queued_exception (whole struct content)
- KVM_REQ_TRIPLE_FAULT (from vcpu.requests)

Unclear points (for me) from the last discussion:

- sipi_vector
- MCE (covered via kvm_queued_exception, or does it require more?)

Please extend or correct the list as required.

Jan
