I'll follow up in that patch.

Hi, There are two patch series combined in this one because I have rebased my patch series (patches 8 to 13) on top of Vitaly's "Hyper-V invariant TSC control feature" (patches 1 to 7). https://lore.kernel.org/kvm/87o7szouyr.fsf@ovpn-194-185.brq.redhat.com/ Vitaly's series had some small merge conflicts on the KVM queue branch I have fixed them in this series, no code changes. My patches (8 to 13) add Hyper-V extended hypercall support and selftests. v4: - Changed vm_vaddr_t to vm_paddr_t in hyperv_extended_hypercalls. - Changed ASSERT_EXIT_REASON to TEST_ASSERT_KVM_EXIT_REASON v3: https://lore.kernel.org/lkml/20221205191430.2455108-1-vipinsh@google.com/ - Rebased on top of Vitaly's "Hyper-V invariant TSC control feature" series. - Removed enabling KVM_CAP_HYPERV_ENFORCE_CPUID in hyperv_extended_hypercalls test. v2: https://lore.kernel.org/lkml/20221121234026.3037083-1-vipinsh@google.com/ - Intorduced ASSERT_EXIT_REASON macro and replaced all occurences of TEST_ASSERT for vcpu exit reason. - Skip hyperv_extended_hypercalls test if extended hypercalls are not supported by the kernel. - Rebased with latest KVM queue. - Addressed all of the comments in patch 6 of v1. v1: https://lore.kernel.org/lkml/20221105045704.2315186-1-vipinsh@google.com/ RFC: https://lore.kernel.org/lkml/20221021185916.1494314-1-vipinsh@google.com/ Vipin Sharma (6): KVM: x86: hyper-v: Use common code for hypercall userspace exit KVM: x86: hyper-v: Add extended hypercall support in Hyper-v KVM: selftests: Test Hyper-V extended hypercall enablement KVM: selftests: Replace hardcoded Linux OS id with HYPERV_LINUX_OS_ID KVM: selftests: Make vCPU exit reason test assertion common.
