The recent addition of support for testing with the x86 specific quirk KVM_X86_QUIRK_SLOT_ZAP_ALL disabled in the generic memslot tests broke the build of the KVM selftests for all other architectures: In file included from include/kvm_util.h:8, from include/memstress.h:13, from memslot_modification_stress_test.c:21: memslot_modification_stress_test.c: In function ‘main’: memslot_modification_stress_test.c:176:38: error: ‘KVM_X86_QUIRK_SLOT_ZAP_ALL’ undeclared (first use in this function) 176 | KVM_X86_QUIRK_SLOT_ZAP_ALL); | ^~~~~~~~~~~~~~~~~~~~~~~~~~ Add __x86_64__ guard defines to avoid building the relevant code on other architectures. Fixes: 61de4c34b51c ("KVM: selftests: Test memslot move in memslot_perf_test with quirk disabled") Fixes: 218f6415004a ("KVM: selftests: Allow slot modification stress test with quirk disabled") Reported-by: Aishwarya TCV <aishwarya.tcv@xxxxxxx> Signed-off-by: Mark Brown <broonie@xxxxxxxxxx> --- This is obviously disruptive for testing of KVM changes on non-x86 architectures. --- tools/testing/selftests/kvm/memslot_modification_stress_test.c | 2 ++ tools/testing/selftests/kvm/memslot_perf_test.c | 6 ++++++ 2 files changed, 8 insertions(+) diff --git a/tools/testing/selftests/kvm/memslot_modification_stress_test.c b/tools/testing/selftests/kvm/memslot_modification_stress_test.c index e3343f0df9e1..c81a84990eab 100644 --- a/tools/testing/selftests/kvm/memslot_modification_stress_test.c +++ b/tools/testing/selftests/kvm/memslot_modification_stress_test.c @@ -169,12 +169,14 @@ int main(int argc, char *argv[]) case 'i': p.nr_iterations = atoi_positive("Number of iterations", optarg); break; +#ifdef __x86_64__ case 'q': p.disable_slot_zap_quirk = true; TEST_REQUIRE(kvm_check_cap(KVM_CAP_DISABLE_QUIRKS2) & KVM_X86_QUIRK_SLOT_ZAP_ALL); break; +#endif case 'h': default: help(argv[0]); diff --git a/tools/testing/selftests/kvm/memslot_perf_test.c b/tools/testing/selftests/kvm/memslot_perf_test.c index 893366982f77..989ffe0d047f 100644 --- a/tools/testing/selftests/kvm/memslot_perf_test.c +++ b/tools/testing/selftests/kvm/memslot_perf_test.c @@ -113,7 +113,9 @@ static_assert(ATOMIC_BOOL_LOCK_FREE == 2, "atomic bool is not lockless"); static sem_t vcpu_ready; static bool map_unmap_verify; +#ifdef __x86_64__ static bool disable_slot_zap_quirk; +#endif static bool verbose; #define pr_info_v(...) \ @@ -579,8 +581,10 @@ static bool test_memslot_move_prepare(struct vm_data *data, uint32_t guest_page_size = data->vm->page_size; uint64_t movesrcgpa, movetestgpa; +#ifdef __x86_64__ if (disable_slot_zap_quirk) vm_enable_cap(data->vm, KVM_CAP_DISABLE_QUIRKS2, KVM_X86_QUIRK_SLOT_ZAP_ALL); +#endif movesrcgpa = vm_slot2gpa(data, data->nslots - 1); @@ -971,11 +975,13 @@ static bool parse_args(int argc, char *argv[], case 'd': map_unmap_verify = true; break; +#ifdef __x86_64__ case 'q': disable_slot_zap_quirk = true; TEST_REQUIRE(kvm_check_cap(KVM_CAP_DISABLE_QUIRKS2) & KVM_X86_QUIRK_SLOT_ZAP_ALL); break; +#endif case 's': targs->nslots = atoi_paranoid(optarg); if (targs->nslots <= 1 && targs->nslots != -1) { --- base-commit: 9852d85ec9d492ebef56dc5f229416c925758edc change-id: 20240930-kvm-build-breakage-a542f46d78f9 Best regards, -- Mark Brown <broonie@xxxxxxxxxx>
