(39fe2fc96694 "selftests: kvm: make allocation of extra memory take effect") changed the meaning of extra_mem_pages and treated it as slot0 memory size. In fact extra_mem_pages is used for non-slot0 memory size, there is no custom slot0 memory size support. See discuss in https://lkml.org/lkml/2021/6/3/551 for more details. This patchset restores extra_mem_pages's original meaning and adds support for custom slot0 memory with a new parameter slot0_mem_pages. Run below command, all 39 tests passed. # make -C tools/testing/selftests/ TARGETS=kvm run_tests Zhenzhong Duan (3): Revert "selftests: kvm: make allocation of extra memory take effect" Revert "selftests: kvm: fix overlapping addresses in memslot_perf_test" selftests: kvm: Add support for customized slot0 memory size .../testing/selftests/kvm/include/kvm_util.h | 7 +-- .../selftests/kvm/kvm_page_table_test.c | 2 +- tools/testing/selftests/kvm/lib/kvm_util.c | 47 +++++++++++++++---- .../selftests/kvm/lib/perf_test_util.c | 2 +- .../testing/selftests/kvm/memslot_perf_test.c | 2 +- 5 files changed, 45 insertions(+), 15 deletions(-) -- 2.25.1
