[PATCH v2 0/2] s390x: KVM: CPU Topology

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



To provide Topology information to the guest through the STSI
instruction, we need to forward STSI with Function Code 15 to
QEMU which will take care to provide the right information to
the guest.

To let the guest use the PTF instruction and ask if a topology
change occured we add a new KVM capability to enable the topology
facility.

  s390x: KVM: accept STSI for CPU topology information
  s390:kvm: Topology expose TOPOLOGY facility
