C Specification

The VkPhysicalDeviceShaderAtomicFloatFeaturesEXT structure is defined as:

// Provided by VK_EXT_shader_atomic_float
typedef struct VkPhysicalDeviceShaderAtomicFloatFeaturesEXT {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           shaderBufferFloat32Atomics;
    VkBool32           shaderBufferFloat32AtomicAdd;
    VkBool32           shaderBufferFloat64Atomics;
    VkBool32           shaderBufferFloat64AtomicAdd;
    VkBool32           shaderSharedFloat32Atomics;
    VkBool32           shaderSharedFloat32AtomicAdd;
    VkBool32           shaderSharedFloat64Atomics;
    VkBool32           shaderSharedFloat64AtomicAdd;
    VkBool32           shaderImageFloat32Atomics;
    VkBool32           shaderImageFloat32AtomicAdd;
    VkBool32           sparseImageFloat32Atomics;
    VkBool32           sparseImageFloat32AtomicAdd;
} VkPhysicalDeviceShaderAtomicFloatFeaturesEXT;

Members

This structure describes the following features:

Description

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • shaderBufferFloat32Atomics indicates whether shaders can perform 32-bit floating-point load, store and exchange atomic operations on storage buffers.

  • shaderBufferFloat32AtomicAdd indicates whether shaders can perform 32-bit floating-point add atomic operations on storage buffers.

  • shaderBufferFloat64Atomics indicates whether shaders can perform 64-bit floating-point load, store and exchange atomic operations on storage buffers.

  • shaderBufferFloat64AtomicAdd indicates whether shaders can perform 64-bit floating-point add atomic operations on storage buffers.

  • shaderSharedFloat32Atomics indicates whether shaders can perform 32-bit floating-point load, store and exchange atomic operations on shared memory.

  • shaderSharedFloat32AtomicAdd indicates whether shaders can perform 32-bit floating-point add atomic operations on shared memory.

  • shaderSharedFloat64Atomics indicates whether shaders can perform 64-bit floating-point load, store and exchange atomic operations on shared memory.

  • shaderSharedFloat64AtomicAdd indicates whether shaders can perform 64-bit floating-point add atomic operations on shared memory.

  • shaderImageFloat32Atomics indicates whether shaders can perform 32-bit floating-point load, store and exchange atomic image operations.

  • shaderImageFloat32AtomicAdd indicates whether shaders can perform 32-bit floating-point add atomic image operations.

  • sparseImageFloat32Atomics indicates whether 32-bit floating-point load, store and exchange atomic operations can be used on sparse images.

  • sparseImageFloat32AtomicAdd indicates whether 32-bit floating-point add atomic operations can be used on sparse images.

If the VkPhysicalDeviceShaderAtomicFloatFeaturesEXT 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. VkPhysicalDeviceShaderAtomicFloatFeaturesEXT can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

  • VUID-VkPhysicalDeviceShaderAtomicFloatFeaturesEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_ATOMIC_FLOAT_FEATURES_EXT
