Please pull selftests fixes/cleanups for 6.7. The big change is adding __printf() annotation to the guest printf/assert helpers, which is waaay better than me playing whack-a-mole when tests fail (I'm still laughing at myself for not realizing what that annotation does). The following changes since commit e9e60c82fe391d04db55a91c733df4a017c28b2f: selftests/kvm: fix compilation on non-x86_64 platforms (2023-11-21 11:58:25 -0500) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-selftests-6.7-rcN for you to fetch changes up to 1b2658e4c709135fe1910423d3216632f641baf9: KVM: selftests: Annotate guest ucall, printf, and assert helpers with __printf() (2023-12-01 08:15:41 -0800) ---------------------------------------------------------------- KVM selftests fixes for 6.7-rcN: - Fix an annoying goof where the NX hugepage test prints out garbage instead of the magic token needed to run the text. - Fix build errors when a header is delete/moved due to a missing flag in the Makefile. - Detect if KVM bugged/killed a selftest's VM and print out a helpful message instead of complaining that a random ioctl() failed. - Annotate the guest printf/assert helpers with __printf(), and fix the various bugs that were lurking due to lack of said annotation. ---------------------------------------------------------------- David Woodhouse (1): KVM: selftests: add -MP to CFLAGS Sean Christopherson (7): KVM: selftests: Drop the single-underscore ioctl() helpers KVM: selftests: Add logic to detect if ioctl() failed because VM was killed KVM: selftests: Remove x86's so called "MMIO warning" test KVM: selftests: Fix MWAIT error message when guest assertion fails KVM: selftests: Fix benign %llx vs. %lx issues in guest asserts KVM: selftests: Fix broken assert messages in Hyper-V features test KVM: selftests: Annotate guest ucall, printf, and assert helpers with __printf() angquan yu (1): KVM: selftests: Actually print out magic token in NX hugepages skip message tools/testing/selftests/kvm/Makefile | 3 +- .../testing/selftests/kvm/include/kvm_util_base.h | 75 ++++++++----- tools/testing/selftests/kvm/include/test_util.h | 2 +- tools/testing/selftests/kvm/include/ucall_common.h | 7 +- tools/testing/selftests/kvm/lib/kvm_util.c | 2 +- .../testing/selftests/kvm/set_memory_region_test.c | 6 +- .../testing/selftests/kvm/x86_64/hyperv_features.c | 10 +- .../selftests/kvm/x86_64/mmio_warning_test.c | 121 --------------------- .../selftests/kvm/x86_64/monitor_mwait_test.c | 6 +- .../selftests/kvm/x86_64/nx_huge_pages_test.c | 2 +- .../kvm/x86_64/private_mem_conversions_test.c | 2 +- .../kvm/x86_64/svm_nested_soft_inject_test.c | 4 +- .../selftests/kvm/x86_64/vmx_pmu_caps_test.c | 2 +- .../testing/selftests/kvm/x86_64/xcr0_cpuid_test.c | 8 +- 14 files changed, 78 insertions(+), 172 deletions(-) delete mode 100644 tools/testing/selftests/kvm/x86_64/mmio_warning_test.c
