Members

This structure describes the following features:

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
constantAlphaColorBlendFactors indicates whether this implementation supports constant alpha https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#framebuffer-blendfactors used as source or destination color https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#framebuffer-blending.
events indicates whether this implementation supports synchronization using https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#synchronization-events.
imageViewFormatReinterpretation indicates whether this implementation supports a VkImageView being created with a texel format containing a different number of components, or a different number of bits in each component, than the texel format of the underlying VkImage.
imageViewFormatSwizzle indicates whether this implementation supports remapping format components using VkImageViewCreateInfo::components.
imageView2DOn3DImage indicates whether this implementation supports a VkImage being created with the VK_IMAGE_CREATE_2D_ARRAY_COMPATIBLE_BIT flag set, permitting a 2D or 2D array image view to be created on a 3D VkImage.
multisampleArrayImage indicates whether this implementation supports a VkImage being created as a 2D array with multiple samples per texel.
mutableComparisonSamplers indicates whether this implementation allows descriptors with comparison samplers to be updated.
pointPolygons indicates whether this implementation supports https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#primsrast using a point https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#primsrast-polygonmode.
samplerMipLodBias indicates whether this implementation supports setting a mipmap LOD bias value when creating a sampler.
separateStencilMaskRef indicates whether this implementation supports separate front and back https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#fragops-stencil reference values.
shaderSampleRateInterpolationFunctions indicates whether this implementation supports fragment shaders which use the InterpolationFunction capability and the extended instructions InterpolateAtCentroid, InterpolateAtOffset, and InterpolateAtSample from the GLSL.std.450 extended instruction set. This member is only meaningful if the sampleRateShading feature is supported.
tessellationIsolines indicates whether this implementation supports isoline output from the https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#tessellation stage of a graphics pipeline. This member is only meaningful if tessellationShader are supported.
tessellationPointMode indicates whether this implementation supports point output from the https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#tessellation stage of a graphics pipeline. This member is only meaningful if tessellationShader are supported.
triangleFans indicates whether this implementation supports https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#drawing-triangle-fans primitive topology.
vertexAttributeAccessBeyondStride indicates whether this implementation supports accessing a vertex input attribute beyond the stride of the corresponding vertex input binding.

Description

If the VkPhysicalDevicePortabilitySubsetFeaturesKHR structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. VkPhysicalDevicePortabilitySubsetFeaturesKHR can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

VUID-VkPhysicalDevicePortabilitySubsetFeaturesKHR-sType-sType
sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PORTABILITY_SUBSET_FEATURES_KHR
