KVM selftests fixes for 6.6: - Play nice with %llx when formatting guest printf and assert statements. - Clean up stale test metadata. - Zero-initialize structures in memslot perf test to workaround a suspected "may be used uninitialized" false positives from GCC.

KVM: selftests: Force load all supported XSAVE state in state test

2023-10-12T15:08:59+00:00

Extend x86's state to forcefully load *all* host-supported xfeatures by modifying xstate_bv in the saved state. Stuffing xstate_bv ensures that the selftest is verifying KVM's full ABI regardless of whether or not the guest code is successful in getting various xfeatures out of their INIT state, e.g. see the disaster that is/was MPX.

KVM: selftests: Touch relevant XSAVE state in guest for state test

2023-10-12T15:08:58+00:00

Modify support XSAVE state in the "state test's" guest code so that saving and loading state via KVM_{G,S}ET_XSAVE actually does something useful, i.e. so that xstate_bv in XSAVE state isn't empty. Punt on BNDCSR for now, it's easier to just stuff that xfeature from the host side.

KVM: selftests: Remove obsolete and incorrect test case metadata

2023-10-04T19:53:05+00:00

Delete inaccurate descriptions and obsolete metadata for test cases. It adds zero value, and has a non-zero chance of becoming stale and misleading in the future. No functional changes intended.

KVM: selftests: Add x86 properties for Intel PMU in processor.h

2023-08-17T19:58:49+00:00

Add x86 properties for Intel PMU so that tests don't have to manually retrieve the correct CPUID leaf+register, and so that the resulting code is self-documenting.

KVM: riscv: selftests: Add get-reg-list test

2023-08-09T06:45:27+00:00

get-reg-list test is used to check for KVM registers regressions during VM migration which happens when destination host kernel missing registers that the source host kernel has. The blessed list registers was created by running on v6.5-rc3 Signed-off-by: Haibo Xu Reviewed-by: Andrew Jones Signed-off-by: Anup Patel

KVM: selftests: Add skip_set facility to get_reg_list test

2023-08-09T06:45:22+00:00

Add new skips_set members to vcpu_reg_sublist so as to skip set operation on some registers. Suggested-by: Andrew Jones Signed-off-by: Haibo Xu Reviewed-by: Andrew Jones Signed-off-by: Anup Patel

KVM: arm64: selftests: Move finalize_vcpu back to run_test

2023-08-09T06:45:16+00:00

No functional changes. Just move the finalize_vcpu call back to run_test and do weak function trick to prepare for the opration in riscv. Suggested-by: Andrew Jones Signed-off-by: Haibo Xu Reviewed-by: Andrew Jones Signed-off-by: Anup Patel
