x86/hyperv: KVM: Rename "hv_enlightenments" to "hv_vmcb_enlightenments"

2023-04-20T10:35:12+00:00

[ Upstream commit 26b516bb39215cf60aa1fb55d0a6fd73058698fa ] Now that KVM isn't littered with "struct hv_enlightenments" casts, rename the struct to "hv_vmcb_enlightenments" to highlight the fact that the struct is specifically for SVM's VMCB. No functional change intended.

KVM: SVM: Add a proper field for Hyper-V VMCB enlightenments

2023-04-20T10:35:12+00:00

[ Upstream commit 68ae7c7bc56a4504ed5efde7c2f8d6024148a35e ] Add a union to provide hv_enlightenments side-by-side with the sw_reserved bytes that Hyper-V's enlightenments overlay. Casting sw_reserved everywhere is messy, confusing, and unnecessarily unsafe. No functional change intended.

KVM: selftests: Move "struct hv_enlightenments" to x86_64/svm.h

2023-04-20T10:35:12+00:00

[ Upstream commit 381fc63ac0754e05d3921e9d399b89dfdfd2b2e5 ] Move Hyper-V's VMCB "struct hv_enlightenments" to the svm.h header so that the struct can be referenced in "struct vmcb_control_area". Alternatively, a dedicated header for SVM+Hyper-V could be added, a la x86_64/evmcs.h, but it doesn't appear that Hyper-V will end up needing a wholesale replacement for the VMCB. No functional change intended.

KVM: selftests: Fix nx_huge_pages_test on TDP-disabled hosts

2022-09-30T10:39:36+00:00

Map the test's huge page region with 2MiB virtual mappings when TDP is disabled so that KVM can shadow the region with huge pages. This fixes nx_huge_pages_test on hosts where TDP hardware support is disabled. Purposely do not skip this test on TDP-disabled hosts. While we don't care about NX Huge Pages on TDP-disabled hosts from a security perspective, KVM does support it, and so we should test it. For TDP-enabled hosts, continue mapping the region with 4KiB pages to ensure that KVM can map it with huge pages irrespective of the guest mappings.

KVM: selftests: Add helpers to read kvm_{intel,amd} boolean module parameters

2022-09-30T10:39:36+00:00

Add helper functions for reading the value of kvm_intel and kvm_amd boolean module parameters. Use the kvm_intel variant in vm_is_unrestricted_guest() to simplify the check for kvm_intel.unrestricted_guest. No functional change intended.

KVM: selftests: Skip tests that require EPT when it is not available

2022-09-27T11:58:03+00:00

Skip selftests that require EPT support in the VM when it is not available. For example, if running on a machine where kvm_intel.ept=N since KVM does not offer EPT support to guests if EPT is not supported on the host. This commit causes vmx_dirty_log_test to be skipped instead of failing on hosts where kvm_intel.ept=N.
