Hi, new version of the kvm-unit-test s390x CPU topology series. 0. what is new in this new spin ------------------------------- - Running the test on LPAR has been getestet on a46lp21 - splitting big functions in small ones - better tests, reset before test - Diverse rephrasing and functions reordering 1. what is done --------------- - First part is checking PTF errors, for KVM and LPAR - Second part is checking PTF polarization change and STSI with the cpu topology including drawers and books. This tests are run for KVM only. To run these tests under KVM successfully you need Linux 6.0 and the QEMU patches you find at: https://lists.gnu.org/archive/html/qemu-devel/2023-02/msg00081.html Note that Fedora-35 already has the CPU Topology backport for Linux. To start the test in KVM just do: # ./run_tests.sh topology or something like: # ./s390x-run s390x/topology.elf \ -smp 5,drawers=3,books=3,sockets=4,cores=4,maxcpus=144 \ -append '-drawers 3 -books 3 -sockets 4 -cores 4' Of course the declaration of the number of socket and core must be coherent in -smp and -append arguments. To start the tests in LPAR you need to define the loader entry. For example, under RedHat: title topology version topology.bin linux /boot/topology.bin initrd /boot/initramfs-topology.bin.img options -drawers 4 -books 4 -sockets 2 -cores 8 id rhel-0-topology.bin grub_users $grub_users grub_arg --unrestricted grub_class kernel Output of the test is done on the SCLP console.
