Hi, new version of the series with corrections. When facility 11 is available inside the S390x architecture, 2 new instructions are available: PTF and STSI with function code 15. Let's check their availability in QEMU/KVM and their coherence with the CPU topology provided to the QEMU -smp parameter and as argument for the test. To run these tests successfully you will Linux 6.0 and the following QEMU patches (or newer): https://lore.kernel.org/all/20221012162107.91734-1-pmorel@xxxxxxxxxxxxx/#r To start the test just do: # ./run_tests.sh topology or # ./s390x-run s390x/topology.elf \ -smp 5,sockets=4,cores=4,maxcpus=16 \ -append "-mnest 2 -sockets 4 -cores 4" Of course the declaration of the number of socket and core must be coherent in -smp and -append arguments. The "mnest" argument represent the expected nesting level it will be 2 until books and drawer are added to the topology.
