KVM: selftests: Print expected and actual exit reason in KVM exit reason assert

2023-03-14T14:20:09+00:00

Print what KVM exit reason a test was expecting and what it actually got int TEST_ASSERT_KVM_EXIT_REASON(). Signed-off-by: Vipin Sharma Message-Id: <20230204014547.583711-3-vipinsh@google.com> Signed-off-by: Paolo Bonzini

KVM: selftests: Make vCPU exit reason test assertion common

2023-03-14T14:20:09+00:00

Make TEST_ASSERT_KVM_EXIT_REASON() macro and replace all exit reason test assert statements with it. No functional changes intended. Signed-off-by: Vipin Sharma Reviewed-by: David Matlack Message-Id: <20230204014547.583711-2-vipinsh@google.com> Signed-off-by: Paolo Bonzini

KVM: selftests: Add helpers to make Xen-style VMCALL/VMMCALL hypercalls

2023-03-14T14:20:08+00:00

Add wrappers to do hypercalls using VMCALL/VMMCALL and Xen's register ABI (as opposed to full Xen-style hypercalls through a hypervisor provided page). Using the common helpers dedups a pile of code, and uses the native hypercall instruction when running on AMD.

Merge tag 'kvm-x86-selftests-6.3' of https://github.com/kvm-x86/linux into HEAD

2023-02-15T13:34:32+00:00

KVM selftests changes for 6.3: - Cache the CPU vendor (AMD vs. Intel) and use the info to emit the correct hypercall instruction instead of relying on KVM to patch in VMMCALL - A variety of one-off cleanups and fixes

KVM: selftests: Test Hyper-V extended hypercall enablement

2023-02-01T21:46:24+00:00

Test Hyper-V extended hypercall, HV_EXT_CALL_QUERY_CAPABILITIES (0x8001), access denied and invalid parameter cases. Access is denied if CPUID.0x40000003.EBX BIT(20) is not set. Invalid parameter if call has fast bit set. Signed-off-by: Vipin Sharma Link: https://lore.kernel.org/r/20221212183720.4062037-11-vipinsh@google.com Signed-off-by: Sean Christopherson

KVM: selftests: x86: Cache host CPU vendor (AMD vs. Intel)

2023-01-24T18:06:32+00:00

Cache the host CPU vendor for userspace and share it with guest code. All the current callers of this_cpu* actually care about host cpu so they are updated to check host_cpu_is*.

KVM: selftests: x86: Use "this_cpu" prefix for cpu vendor queries

2023-01-24T18:06:31+00:00

Replace is_intel/amd_cpu helpers with this_cpu_* helpers to better convey the intent of querying vendor of the current cpu.

KVM: selftests: Fix a typo in the vcpu_msrs_set assert

The assert incorrectly identifies the ioctl being called. Switch it from KVM_GET_MSRS to KVM_SET_MSRS.

KVM: selftests: Test Hyper-V invariant TSC control

2022-12-29T20:33:33+00:00

Add a test for the newly introduced Hyper-V invariant TSC control feature: - HV_X64_MSR_TSC_INVARIANT_CONTROL is not available without HV_ACCESS_TSC_INVARIANT CPUID bit set and available with it. - BIT(0) of HV_X64_MSR_TSC_INVARIANT_CONTROL controls the filtering of architectural invariant TSC (CPUID.80000007H:EDX[8]) bit.

KVM: selftests: Convert hyperv_features test to using KVM_X86_CPU_FEATURE()

2022-12-29T20:33:31+00:00

hyperv_features test needs to set certain CPUID bits in Hyper-V feature leaves but instead of open coding this, common KVM_X86_CPU_FEATURE() infrastructure can be used.
