This removes the TARGET_S390X and CONFIG_KVM conditions from the CPU commands that are conceptually specific to s390x. Top level stubs are provided to cope with non-s390x targets, or builds without KVM. The removal of CONFIG_KVM is justified by the fact there is no conceptual difference between running 'qemu-system-s390x -accel tcg' on a build with and without KVM built-in, so apps only using TCG can't rely on the CONFIG_KVM in the schema.

|

#
|
|
# Emitted when the guest asks to change the polarization.
|
|
#
|
|
# The guest can tell the host (via the PTF instruction) whether the

# CPUs should be provisioned using horizontal or vertical
|
|
# polarization.

|
|
# On horizontal polarization the host is expected to provision all

|
#
|
|
# On vertical polarization the host can provision each vCPU
|
|
# differently. The guest will get information on the details of the
|
|
# provisioning the next time it uses the STSI(15) instruction.
