Description

The VK_KHR_portability_subset extension allows a non-conformant Vulkan implementation to be built on top of another non-Vulkan graphics API, and identifies differences between that implementation and a fully-conformant native Vulkan implementation.

This extension provides Vulkan implementations with the ability to mark otherwise-required capabilities as unsupported, or to establish additional properties and limits that the application should adhere to in order to guarantee portable behaviour and operation across platforms, including platforms where Vulkan is not natively supported.

The goal of this specification is to document, and make queryable, capabilities which are required to be supported by a fully-conformant Vulkan 1.0 implementation, but may be optional for an implementation of the Vulkan 1.0 Portability Subset.

The intent is that this extension will be advertised only on implementations of the Vulkan 1.0 Portability Subset, and not on conformant implementations of Vulkan 1.0. Fully-conformant Vulkan implementations provide all the required capabilities, and so will not provide this extension. Therefore, the existence of this extension can be used to determine that an implementation is likely not fully conformant with the Vulkan spec.

If this extension is supported by the Vulkan implementation, the application must enable this extension.

This extension defines several new structures that can be chained to the existing structures used by certain standard Vulkan calls, in order to query for non-conformant portable behavior.

Synopsis

data PhysicalDevicePortabilitySubsetFeaturesKHR Source #

VkPhysicalDevicePortabilitySubsetFeaturesKHR - Structure describing the features that may not be supported by an implementation of the Vulkan 1.0 Portability Subset

Members

This structure describes the following features:

Description

If the PhysicalDevicePortabilitySubsetFeaturesKHR 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. PhysicalDevicePortabilitySubsetFeaturesKHR can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

VkPhysicalDevicePortabilitySubsetPropertiesKHR - Structure describing additional properties supported by a portable implementation

Description

If the PhysicalDevicePortabilitySubsetPropertiesKHR structure is included in the pNext chain of the PhysicalDeviceProperties2 structure passed to getPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.
