This 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 capabilies, 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.

data PhysicalDevicePortabilitySubsetFeaturesKHR Source #
VkPhysicalDevicePortabilitySubsetFeaturesKHR - Structure describing the features that may not be supported by an implementation of the Vulkan 1.0 Portability Subset
Members
The members of the PhysicalDevicePortabilitySubsetFeaturesKHR
structure describe the following features:
Description
If the PhysicalDevicePortabilitySubsetFeaturesKHR
structure is
included in the pNext
chain of
PhysicalDeviceFeatures2
,
it is filled with values indicating whether the features are supported.
PhysicalDevicePortabilitySubsetFeaturesKHR
can also be used in the
pNext
chain of DeviceCreateInfo
to enable the
features.
