KVM: selftests: Add aarch64 get-reg-list test

2020-11-08T11:02:45Z

Check for KVM_GET_REG_LIST regressions. The blessed list was created by running on v4.15 with the --core-reg-fixup option. The following script was also used in order to annotate system registers with their names when possible. When new system registers are added the names can just be added manually using the same grep. while read reg; do if [[ ! $reg =~ ARM64_SYS_REG ]]; then printf "\t$reg\n" continue fi encoding=$(echo "$reg" | sed "s/ARM64_SYS_REG(//;s/),//") if ! name=$(grep "$encoding" ../../../../arch/arm64/include/asm/sysreg.h); then printf "\t$reg\n" continue fi name=$(echo "$name" | sed "s/.*SYS_//;s/[\t ]*sys_reg($encoding)$//") printf "\t$reg\t/* $name */\n" done < <(aarch64/get-reg-list --core-reg-fixup --list) Signed-off-by: Andrew Jones Message-Id: <20201029201703.102716-3-drjones@redhat.com> Signed-off-by: Paolo Bonzini

selftests: kvm: test enforcement of paravirtual cpuid features

2020-11-08T11:02:16Z

Add a set of tests that ensure the guest cannot access paravirtual msrs and hypercalls that have been disabled in the KVM_CPUID_FEATURES leaf. Expect a #GP in the case of msr accesses and -KVM_ENOSYS from hypercalls.

KVM: selftests: Add KVM_SET_GUEST_DEBUG test

2020-05-07T10:13:42Z

Covers fundamental tests for KVM_SET_GUEST_DEBUG. It is very close to the debug test in kvm-unit-test, but doing it from outside the guest. Signed-off-by: Peter Xu Message-Id: <20200505205000.188252-4-peterx@redhat.com> Signed-off-by: Paolo Bonzini

KVM: selftests: Add GUEST_ASSERT variants to pass values to host

2020-04-15T16:08:43Z

Add variants of GUEST_ASSERT to pass values back to the host, e.g. to help debug/understand a failure when the the cause of the assert isn't necessarily binary. It'd probably be possible to auto-calculate the number of arguments and just have a single GUEST_ASSERT, but there are a limited number of variants and silently eating arguments could lead to subtle code bugs.
