To: qemu-devel; +Cc: Bharata B Rao, qemu-ppc, david
If KVM_CAP_RPT_INVALIDATE KVM capability is enabled, then
- indicate the availability of H_RPT_INVALIDATE hcall to the guest via
ibm,hypertas-functions property.
- Enable the hcall
Both the above are done only if the new sPAPR machine capability
cap-rpt-invalidate is set.
