[PATCH v19 21/21] tests/avocado: s390x cpu topology query-cpu-polarization

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

 



This test verifies that the qmp query query-cpu-polarization
reports correctly the polarization when the guest requests
a polarization change.
