Here's a follow-up from my RFC series last year:
https://lore.kernel.org/lkml/20221004093131.40392-1-thuth@redhat.com/T/
and from v1 earlier this year:
https://lore.kernel.org/kvm/20230712075910.22480-1-thuth@redhat.com/
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).
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
