Creating more memslots than vCPUs is particuarly interesting as it results in a single vCPU's data chunk being spread across multiple memslots, which in turn results in the test changing attributes across multiple memslots in a single KVM_SET_MEMORY_ATTRIBUTES. This also fixes the issues reported by Mike where the test would crash when run with multiple vCPUs and a single memslot. Sean Christopherson (5): KVM: selftests: Rework fallocate() helper to work across multiple memslots KVM: selftests: Handle memslot splits in private mem conversions test KVM: selftests: Let user specify nr of memslots in private mem conversion KVM: selftests: Use dedicated pattern for testing that mem is shared by default KVM: selftests: Verify default pattern was written in private mem conversion tools/testing/selftests/kvm/lib/kvm_util.c | 34 ++++---- .../kvm/x86_64/private_mem_conversions_test.c | 87 +++++++++++-------- 2 files changed, 69 insertions(+), 52 deletions(-) base-commit: 911b515af3ec5f53992b9cc162cf7d3893c2fbe2 -- 2.42.0.758.gaed0368e0e-goog
