VkPhysicalDeviceGraphicsPipelineLibraryPropertiesEXT

The VkPhysicalDeviceGraphicsPipelineLibraryPropertiesEXT structure is defined as:

typedef struct VkPhysicalDeviceGraphicsPipelineLibraryPropertiesEXT {
    VkStructureType sType;
    void* pNext;
    VkBool32 graphicsPipelineLibraryFastLinking;
    VkBool32 graphicsPipelineLibraryIndependentInterpolationDecoration;
} VkPhysicalDeviceGraphicsPipelineLibraryPropertiesEXT;

• graphicsPipelineLibraryFastLinking indicates whether fast linking of graphics pipelines is supported. If it is VK_TRUE, creating a graphics pipeline entirely from pipeline libraries without VK_PIPELINE_CREATE_LINK_TIME_OPTIMIZATION_BIT_EXT is comparable in cost to recording a command in a command buffer.
• graphicsPipelineLibraryIndependentInterpolationDecoration indicates whether NoPerspective and Flat interpolation decorations in the last vertex processing stage and the fragment shader are required to match when using graphics pipeline libraries. If it is VK_TRUE, the interpolation decorations do not need to match. If it is VK_FALSE, these decorations must either be present in both stages or neither stage in order for a given interface variable to match.

If the VkPhysicalDeviceGraphicsPipelineLibraryPropertiesEXT structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.
