Context data for an exit caused by an unsupported processor feature.

Note

The WHV_X64_UNSUPPORTED_FEATURE_CONTEXT structure applies to x64 partitions only.

Syntax

//
// Context data for an exit caused by the use of an unsupported processor feature
// (WHvRunVpExitReasonUnsupportedFeature)
//
typedef enum WHV_X64_UNSUPPORTED_FEATURE_CODE
{
    WHvUnsupportedFeatureIntercept     = 1,
    WHvUnsupportedFeatureTaskSwitchTss = 2
} WHV_X64_UNSUPPORTED_FEATURE_CODE;

typedef struct WHV_X64_UNSUPPORTED_FEATURE_CONTEXT
{
    WHV_X64_UNSUPPORTED_FEATURE_CODE FeatureCode;
    UINT32 Reserved;
    UINT64 FeatureParameter;
} WHV_X64_UNSUPPORTED_FEATURE_CONTEXT;

Remarks

An exit for an unsupported feature occurs when the virtual processor accesses a feature of the architecture that is not properly virtualized by the hypervisor.
