## Name

VkSpirvResourceTypeFlagBitsEXT - Bitmask specifying different SPIR-V resource declarations

Loading… please wait.

## C Specification

Bits which can be set in VkDescriptorSetAndBindingMappingEXT::`resourceMask`, are:

    // Provided by VK_EXT_descriptor_heap
    typedef enum VkSpirvResourceTypeFlagBitsEXT {
        VK_SPIRV_RESOURCE_TYPE_ALL_EXT = 0x7FFFFFFF,
        VK_SPIRV_RESOURCE_TYPE_SAMPLER_BIT_EXT = 0x00000001,
        VK_SPIRV_RESOURCE_TYPE_SAMPLED_IMAGE_BIT_EXT = 0x00000002,
        VK_SPIRV_RESOURCE_TYPE_READ_ONLY_IMAGE_BIT_EXT = 0x00000004,
        VK_SPIRV_RESOURCE_TYPE_READ_WRITE_IMAGE_BIT_EXT = 0x00000008,
        VK_SPIRV_RESOURCE_TYPE_COMBINED_SAMPLED_IMAGE_BIT_EXT = 0x00000010,
        VK_SPIRV_RESOURCE_TYPE_UNIFORM_BUFFER_BIT_EXT = 0x00000020,
        VK_SPIRV_RESOURCE_TYPE_READ_ONLY_STORAGE_BUFFER_BIT_EXT = 0x00000040,
        VK_SPIRV_RESOURCE_TYPE_READ_WRITE_STORAGE_BUFFER_BIT_EXT = 0x00000080,
      // Provided by VK_EXT_descriptor_heap with VK_KHR_ray_tracing_pipeline or VK_NV_ray_tracing
        VK_SPIRV_RESOURCE_TYPE_ACCELERATION_STRUCTURE_BIT_EXT = 0x00000100,
      // Provided by VK_EXT_descriptor_heap with VK_ARM_tensors
        VK_SPIRV_RESOURCE_TYPE_TENSOR_BIT_ARM = 0x00000200,
    } VkSpirvResourceTypeFlagBitsEXT;

## Description

- VK_SPIRV_RESOURCE_TYPE_ALL_EXT specifies that all resource declarations are included.

- VK_SPIRV_RESOURCE_TYPE_SAMPLER_BIT_EXT specifies `OpTypeSampler` variables.

- VK_SPIRV_RESOURCE_TYPE_SAMPLED_IMAGE_BIT_EXT specifies `OpTypeImage` variables with a `Sampled` parameter of 1.

- VK_SPIRV_RESOURCE_TYPE_READ_ONLY_IMAGE_BIT_EXT specifies `OpTypeImage` variables with a `Sampled` parameter of 2 and decorated with `NonWritable`.

- VK_SPIRV_RESOURCE_TYPE_READ_WRITE_IMAGE_BIT_EXT specifies `OpTypeImage` variables with a `Sampled` parameter of 2 and not decorated with `NonWritable`.

- VK_SPIRV_RESOURCE_TYPE_COMBINED_SAMPLED_IMAGE_BIT_EXT specifies `OpTypeSampledImage` variables.

- VK_SPIRV_RESOURCE_TYPE_UNIFORM_BUFFER_BIT_EXT specifies `OpTypeStruct` variables in the `Uniform` storage class decorated with `Block`

- VK_SPIRV_RESOURCE_TYPE_READ_ONLY_STORAGE_BUFFER_BIT_EXT specifies `OpTypeStruct` variables either in the `StorageBuffer` storage class decorated with `Block` or in the `Uniform` storage class decorated with `BufferBlock`, and decorated with `NonWritable`

- VK_SPIRV_RESOURCE_TYPE_READ_WRITE_STORAGE_BUFFER_BIT_EXT specifies `OpTypeStruct` variables either in the `StorageBuffer` storage class decorated with `Block` or in the `Uniform` storage class decorated with `BufferBlock`, but not decorated with `NonWritable`

- VK_SPIRV_RESOURCE_TYPE_ACCELERATION_STRUCTURE_BIT_EXT specifies `OpTypeAccelerationStructureKHR` variables

- VK_SPIRV_RESOURCE_TYPE_TENSOR_BIT_ARM specifies `OpTypeTensorARM` variables
