Members
The members of the VkPhysicalDeviceDescriptorIndexingFeaturesEXT
structure describe the following features:
Description
-
shaderInputAttachmentArrayDynamicIndexing
indicates whether arrays of input attachments can be indexed by dynamically uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type ofVK_DESCRIPTOR_TYPE_INPUT_ATTACHMENT
must be indexed only by constant integral expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare theInputAttachmentArrayDynamicIndexingEXT
capability. -
shaderUniformTexelBufferArrayDynamicIndexing
indicates whether arrays of uniform texel buffers can be indexed by dynamically uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type ofVK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER
must be indexed only by constant integral expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare theUniformTexelBufferArrayDynamicIndexingEXT
capability. -
shaderStorageTexelBufferArrayDynamicIndexing
indicates whether arrays of storage texel buffers can be indexed by dynamically uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type ofVK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER
must be indexed only by constant integral expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare theStorageTexelBufferArrayDynamicIndexingEXT
capability. -
shaderUniformBufferArrayNonUniformIndexing
indicates whether arrays of uniform buffers can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type ofVK_DESCRIPTOR_TYPE_UNIFORM_BUFFER
orVK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC
must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare theUniformBufferArrayNonUniformIndexingEXT
capability. -
shaderSampledImageArrayNonUniformIndexing
indicates whether arrays of samplers or sampled images can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type ofVK_DESCRIPTOR_TYPE_SAMPLER
,VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER
, orVK_DESCRIPTOR_TYPE_SAMPLED_IMAGE
must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare theSampledImageArrayNonUniformIndexingEXT
capability. -
shaderStorageBufferArrayNonUniformIndexing
indicates whether arrays of storage buffers can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type ofVK_DESCRIPTOR_TYPE_STORAGE_BUFFER
orVK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC
must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare theStorageBufferArrayNonUniformIndexingEXT
capability. -
shaderStorageImageArrayNonUniformIndexing
indicates whether arrays of storage images can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type ofVK_DESCRIPTOR_TYPE_STORAGE_IMAGE
must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare theStorageImageArrayNonUniformIndexingEXT
capability. -
shaderInputAttachmentArrayNonUniformIndexing
indicates whether arrays of input attachments can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type ofVK_DESCRIPTOR_TYPE_INPUT_ATTACHMENT
must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare theInputAttachmentArrayNonUniformIndexingEXT
capability. -
shaderUniformTexelBufferArrayNonUniformIndexing
indicates whether arrays of uniform texel buffers can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type ofVK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER
must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare theUniformTexelBufferArrayNonUniformIndexingEXT
capability. -
shaderStorageTexelBufferArrayNonUniformIndexing
indicates whether arrays of storage texel buffers can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type ofVK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER
must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare theStorageTexelBufferArrayNonUniformIndexingEXT
capability. -
descriptorBindingUniformBufferUpdateAfterBind
indicates whether the implementation supports updating uniform buffer descriptors after a set is bound. If this feature is not enabled,VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT_EXT
must not be used withVK_DESCRIPTOR_TYPE_UNIFORM_BUFFER
. -
descriptorBindingSampledImageUpdateAfterBind
indicates whether the implementation supports updating sampled image descriptors after a set is bound. If this feature is not enabled,VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT_EXT
must not be used withVK_DESCRIPTOR_TYPE_SAMPLER
,VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER
, orVK_DESCRIPTOR_TYPE_SAMPLED_IMAGE
. -
descriptorBindingStorageImageUpdateAfterBind
indicates whether the implementation supports updating storage image descriptors after a set is bound. If this feature is not enabled,VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT_EXT
must not be used withVK_DESCRIPTOR_TYPE_STORAGE_IMAGE
. -
descriptorBindingStorageBufferUpdateAfterBind
indicates whether the implementation supports updating storage buffer descriptors after a set is bound. If this feature is not enabled,VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT_EXT
must not be used withVK_DESCRIPTOR_TYPE_STORAGE_BUFFER
. -
descriptorBindingUniformTexelBufferUpdateAfterBind
indicates whether the implementation supports updating uniform texel buffer descriptors after a set is bound. If this feature is not enabled,VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT_EXT
must not be used withVK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER
. -
descriptorBindingStorageTexelBufferUpdateAfterBind
indicates whether the implementation supports updating storage texel buffer descriptors after a set is bound. If this feature is not enabled,VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT_EXT
must not be used withVK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER
. -
descriptorBindingUpdateUnusedWhilePending
indicates whether the implementation supports updating descriptors while the set is in use. If this feature is not enabled,VK_DESCRIPTOR_BINDING_UPDATE_UNUSED_WHILE_PENDING_BIT_EXT
must not be used. -
descriptorBindingPartiallyBound
indicates whether the implementation supports statically using a descriptor set binding in which some descriptors are not valid. If this feature is not enabled,VK_DESCRIPTOR_BINDING_PARTIALLY_BOUND_BIT_EXT
must not be used. -
descriptorBindingVariableDescriptorCount
indicates whether the implementation supports descriptor sets with a variable-sized last binding. If this feature is not enabled,VK_DESCRIPTOR_BINDING_VARIABLE_DESCRIPTOR_COUNT_BIT_EXT

runtimeDescriptorArray
indicates whether the implementation supports the SPIR-VRuntimeDescriptorArrayEXT
capability. If this feature is not enabled, descriptors must not be declared in runtime arrays.
If the VkPhysicalDeviceDescriptorIndexingFeaturesEXT
structure is
included in the pNext
chain of VkPhysicalDeviceFeatures2, it is
filled with values indicating whether each feature is supported.
VkPhysicalDeviceDescriptorIndexingFeaturesEXT
can also be used in the
pNext
chain of VkDeviceCreateInfo to enable features.
