This KVM selftests was ported from aarch64 arch_timer and tested with Linux v6.6-rc1 on a Qemu riscv64 virt machine. --- Changed since v2: * Rebase to Linux 6.6-rc1 * Add separate patch for kvm/Makefile improvement * Move aarch64 specific macros to aarch64/arch_timer.c * Add -DCONFIG_64BIT to kvm/Makefile CFLAGS to ensure only 64bit registers were available in csr.h * Avoid some #ifdef in kvm/arch_timer.c by setting some aarch64 specific variable to 0 on risc-v Haibo Xu (9): KVM: selftests: Unify the codes for guest exception handling KVM: selftests: Unify the makefile rule for split targets KVM: arm64: selftests: Split arch_timer test code tools: riscv: Add header file csr.h KVM: riscv: selftests: Switch to use macro from csr.h KVM: riscv: selftests: Add exception handling support KVM: riscv: selftests: Add guest helper to get vcpu id KVM: riscv: selftests: Change vcpu_has_ext to a common function KVM: riscv: selftests: Add sstc timer test tools/arch/riscv/include/asm/csr.h | 521 ++++++++++++++++++ tools/testing/selftests/kvm/Makefile | 14 +- .../selftests/kvm/aarch64/arch_timer.c | 291 +--------- .../selftests/kvm/aarch64/debug-exceptions.c | 4 +- .../selftests/kvm/aarch64/page_fault_test.c | 4 +- .../testing/selftests/kvm/aarch64/vgic_irq.c | 4 +- tools/testing/selftests/kvm/arch_timer.c | 250 +++++++++ .../selftests/kvm/include/aarch64/processor.h | 12 +- .../selftests/kvm/include/kvm_util_base.h | 9 + .../selftests/kvm/include/riscv/arch_timer.h | 80 +++ .../selftests/kvm/include/riscv/processor.h | 63 ++- .../testing/selftests/kvm/include/test_util.h | 2 + .../selftests/kvm/include/timer_test.h | 43 ++ .../selftests/kvm/include/x86_64/processor.h | 5 - .../selftests/kvm/lib/aarch64/processor.c | 6 +- .../selftests/kvm/lib/riscv/handlers.S | 101 ++++ .../selftests/kvm/lib/riscv/processor.c | 86 +++ .../selftests/kvm/lib/x86_64/processor.c | 4 +- .../testing/selftests/kvm/riscv/arch_timer.c | 107 ++++ .../selftests/kvm/riscv/get-reg-list.c | 16 +- tools/testing/selftests/kvm/x86_64/amx_test.c | 4 +- .../selftests/kvm/x86_64/fix_hypercall_test.c | 4 +- .../selftests/kvm/x86_64/hyperv_evmcs.c | 4 +- .../selftests/kvm/x86_64/hyperv_features.c | 8 +- .../testing/selftests/kvm/x86_64/hyperv_ipi.c | 6 +- .../selftests/kvm/x86_64/kvm_pv_test.c | 4 +- .../selftests/kvm/x86_64/monitor_mwait_test.c | 4 +- .../kvm/x86_64/pmu_event_filter_test.c | 8 +- .../smaller_maxphyaddr_emulation_test.c | 4 +- .../selftests/kvm/x86_64/svm_int_ctl_test.c | 4 +- .../kvm/x86_64/svm_nested_shutdown_test.c | 4 +- .../kvm/x86_64/svm_nested_soft_inject_test.c | 4 +- .../kvm/x86_64/ucna_injection_test.c | 8 +- .../kvm/x86_64/userspace_msr_exit_test.c | 4 +- .../vmx_exception_with_invalid_guest_state.c | 4 +- .../selftests/kvm/x86_64/vmx_pmu_caps_test.c | 4 +- .../selftests/kvm/x86_64/xapic_ipi_test.c | 4 +- .../selftests/kvm/x86_64/xcr0_cpuid_test.c | 4 +- .../selftests/kvm/x86_64/xen_shinfo_test.c | 4 +- 39 files changed, 1338 insertions(+), 374 deletions(-) create mode 100644 tools/arch/riscv/include/asm/csr.h create mode 100644 tools/testing/selftests/kvm/arch_timer.c create mode 100644 tools/testing/selftests/kvm/include/riscv/arch_timer.h create mode 100644 tools/testing/selftests/kvm/include/timer_test.h create mode 100644 tools/testing/selftests/kvm/lib/riscv/handlers.S create mode 100644 tools/testing/selftests/kvm/riscv/arch_timer.c
