Description

This extension supports new VkPhysicalDeviceDataGraphProcessingEngineTypeARM, and VkPhysicalDeviceDataGraphOperationTypeARM types for data graph pipelines added in VK_ARM_data_graph.

A new pipeline cache type is also added to seamlessly import ML models such as ONNX through QNN workflow, and run them on the device or an external compute engine.
