[PATCH v3 0/8] Use TAP in some more x86 KVM selftests

by Thomas Huth

Basic idea of this series is now to use the kselftest_harness.h framework to get TAP output in the tests, so that it is easier for the user to see what is going on, and e.g. to be able to detect whether a certain test is part of the test binary or not (which is useful when tests get extended in the course of time). Since most tests also need a vcpu, we introduce our own macros to define such tests, so we don't have to repeat this code all over the place. v3: - Add patch from Sean to allow setting vCPU's entry points seperately - Let each test define the entry point via KVM_ONE_VCPU_TEST(), don't do it globally from KVM_ONE_VCPU_TEST_SUITE() v2: - Dropped the "Rename the ASSERT_EQ macro" patch (already merged) - Split the fixes in the sync_regs_test into separate patches (see the first two patches) - Introduce the KVM_ONE_VCPU_TEST_SUITE() macro as suggested by Sean (see third patch) and use it in the following patches - Add a new patch to convert vmx_pmu_caps_test.c, too Sean Christopherson (1): KVM: selftests: Move setting a vCPU's entry point to a dedicated API Thomas Huth (7): KVM: selftests: x86: sync_regs_test: Use vcpu_run() where appropriate KVM: selftests: x86: sync_regs_test: Get regs structure before modifying it KVM: selftests: Add a macro to define a test with one vcpu KVM: selftests: x86: Use TAP interface in the sync_regs test KVM: selftests: x86: Use TAP interface in the fix_hypercall test KVM: selftests: x86: Use TAP interface in the vmx_pmu_caps test KVM: selftests: x86: Use TAP interface in the userspace_msr_exit test .../selftests/kvm/include/kvm_test_harness.h | 36 ++++++ .../selftests/kvm/include/kvm_util_base.h | 11 +- .../selftests/kvm/lib/aarch64/processor.c | 23 +++- .../selftests/kvm/lib/riscv/processor.c | 9 +- .../selftests/kvm/lib/s390x/processor.c | 13 +- .../selftests/kvm/lib/x86_64/processor.c | 13 +- .../selftests/kvm/x86_64/fix_hypercall_test.c | 27 ++-- .../selftests/kvm/x86_64/sync_regs_test.c | 121 +++++++++++++----- .../kvm/x86_64/userspace_msr_exit_test.c | 52 ++------ .../selftests/kvm/x86_64/vmx_pmu_caps_test.c | 50 ++------ 10 files changed, 215 insertions(+), 140 deletions(-) create mode 100644 tools/testing/selftests/kvm/include/kvm_test_harness.h -- 2.43.0

[PATCH net-next] selftests: vxlan_mdb: Avoid duplicate test names

Rename some test cases to avoid overlapping test names which is problematic for the kernel test robot. No changes in the test's logic.
