selftests: KVM: SVM: Add vmcall test

2020-02-12T19:09:39+00:00

L2 guest calls vmcall and L1 checks the exit status does correspond. Signed-off-by: Eric Auger Reviewed-by: Vitaly Kuznetsov Reviewed-by: Miaohe Lin Tested-by: Wei Huang Signed-off-by: Paolo Bonzini

KVM: VMX: Fix the spelling of CPU_BASED_USE_TSC_OFFSETTING

2020-01-08T17:15:59+00:00

The mis-spelling is found by checkpatch.pl, so fix them. Signed-off-by: Xiaoyao Li Signed-off-by: Paolo Bonzini

kvm: tests: Add test to verify MSR_IA32_XSS

2019-10-22T13:48:15+00:00

Ensure that IA32_XSS appears in KVM_GET_MSR_INDEX_LIST if it can be set to a non-zero value. Reviewed-by: Jim Mattson Signed-off-by: Aaron Lewis Change-Id: Ia2d644f69e2d6d8c27d7e0a7a45c2bf9c42bf5ff Signed-off-by: Paolo Bonzini

selftests: kvm: fix sync_regs_test with newer gccs

2019-10-22T11:31:18+00:00

Commit 204c91eff798a ("KVM: selftests: do not blindly clobber registers in guest asm") was intended to make test more gcc-proof, however, the result is exactly the opposite: on newer gccs (e.g. 8.2.1) the test breaks with ==== Test Assertion Failure ==== x86_64/sync_regs_test.c:168: run->s.regs.regs.rbx == 0xBAD1DEA + 1 pid=14170 tid=14170 - Invalid argument 1 0x00000000004015b3: main at sync_regs_test.c:166 (discriminator 6) 2 0x00007f413fb66412: ?? ??:0 3 0x000000000040191d: _start at ??:? rbx sync regs value incorrect 0x1. Apparently, compile is still free to play games with registers even when they have variables attached. Re-write guest code with 'asm volatile' by embedding ucall there and making sure rbx is preserved.

selftests: kvm: vmx_dirty_log_test: skip the test when VMX is not supported

2019-10-22T11:31:17+00:00

vmx_dirty_log_test fails on AMD and this is no surprise as it is VMX specific. Bail early when nested VMX is unsupported. Signed-off-by: Vitaly Kuznetsov Signed-off-by: Paolo Bonzini

selftests: kvm: consolidate VMX support checks

2019-10-22T11:31:16+00:00

vmx_* tests require VMX and three of them implement the same check. Move it to vmx library. Signed-off-by: Vitaly Kuznetsov Signed-off-by: Paolo Bonzini

selftests: kvm: vmx_set_nested_state_test: don't check for VMX support twice

2019-10-22T11:31:16+00:00

vmx_set_nested_state_test() checks if VMX is supported twice: in the very beginning (and skips the whole test if it's not) and before doing test_vmx_nested_state(). One should be enough. Signed-off-by: Vitaly Kuznetsov Signed-off-by: Paolo Bonzini

selftests: kvm: add test for dirty logging inside nested guests

2019-09-27T11:13:40+00:00

Check that accesses by nested guests are logged according to the L1 physical addresses rather than L2. Most of the patch is really adding EPT support to the testing framework. Signed-off-by: Paolo Bonzini

KVM: selftests: hyperv_cpuid: add check for NoNonArchitecturalCoreSharing bit

2019-09-24T11:37:31+00:00

The bit is supposed to be '1' when SMT is not supported or forcefully disabled and '0' otherwise. Signed-off-by: Vitaly Kuznetsov Signed-off-by: Paolo Bonzini

selftests/kvm: make platform_info_test pass on AMD

2019-08-21T17:08:18+00:00

test_msr_platform_info_disabled() generates EXIT_SHUTDOWN but VMCB state is undefined after that so an attempt to launch this guest again from test_msr_platform_info_enabled() fails. Reorder the tests to make test pass. Signed-off-by: Vitaly Kuznetsov Signed-off-by: Paolo Bonzini
