VkPhysicalDeviceShaderAtomicFloatFeaturesEXT

The VkPhysicalDeviceShaderAtomicFloatFeaturesEXT structure is defined as:

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;

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.
• 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 and payload memory.
• shaderSharedFloat32AtomicAdd indicates whether shaders can perform 32-bit floating-point add atomic operations on shared and payload memory.
• shaderSharedFloat64Atomics indicates whether shaders can perform 64-bit floating-point load, store and exchange atomic operations on shared and payload memory.
• shaderSharedFloat64AtomicAdd indicates whether shaders can perform 64-bit floating-point add atomic operations on shared and payload 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. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceShaderAtomicFloatFeaturesEXT, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.
