Vitaly Kuznetsov 3bf0fcd754 KVM: selftests: Speed up set_memory_region_test ... After commit 4fc096a99e ("KVM: Raise the maximum number of user memslots") set_memory_region_test may take too long, reports are that the default timeout value we have (120s) may not be enough even on a physical host. Speed things up a bit by throwing away vm_userspace_mem_region_add() usage from test_add_max_memory_regions(), we don't really need to do the majority of the stuff it does for the sake of this test. On my AMD EPYC 7401P, # time ./set_memory_region_test pre-patch: Testing KVM_RUN with zero added memory regions Allowed number of memory slots: 32764 Adding slots 0..32763, each memory region with 2048K size Testing MOVE of in-use region, 10 loops Testing DELETE of in-use region, 10 loops real 0m44.917s user 0m7.416s sys 0m34.601s post-patch: Testing KVM_RUN with zero added memory regions Allowed number of memory slots: 32764 Adding slots 0..32763, each memory region with 2048K size Testing MOVE of in-use region, 10 loops Testing DELETE of in-use region, 10 loops real 0m20.714s user 0m0.109s sys 0m18.359s Reported-by: kernel test robot <oliver.sang@intel.com> Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Message-Id: <20210426130121.758229-1-vkuznets@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>		2021-04-26 12:21:27 -04:00
