DML_FEATURE_DATA_FEATURE_LEVELS structure (directml.h)

Provides detail about the feature levels supported by a DirectML device. See IDMLDevice::CheckFeatureSupport. The feature constant is DML_FEATURE_FEATURE_LEVELS, and the query data type is DML_FEATURE_QUERY_FEATURE_LEVELS.

Syntax

struct DML_FEATURE_DATA_FEATURE_LEVELS {
  DML_FEATURE_LEVEL MaxSupportedFeatureLevel;
};

Members

MaxSupportedFeatureLevel

Type: DML_FEATURE_LEVEL

The highest feature level supplied in the query structure's RequestedFeatureLevels (see DML_FEATURE_DATA_FEATURE_LEVELS) that is supported by this device.

Note

Because this feature query only ever returns one of the values supplied in RequestedFeatureLevels, it's possible that the device supports an even higher feature level than the one returned by this query.

For example, DirectML version 1.4.0 supports a feature level of DML_FEATURE_LEVEL_3_0. If the RequestedFeatureLevels array contained only DML_FEATURE_LEVEL_1_0 and DML_FEATURE_LEVEL_2_0, then this query would return DML_FEATURE_LEVEL_2_0, which is lower than the true feature level (3_0) supported by the device.

Availability

This API was introduced in DirectML version 1.1.0.
