VkPhysicalDeviceShaderBfloat16FeaturesKHR - Structure describing bfloat16 features that can be supported by the implementation

Members

This structure describes the following features:

Description

If the PhysicalDeviceShaderBfloat16FeaturesKHR structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a Device with any features described by PhysicalDeviceShaderBfloat16FeaturesKHR, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.
