Members
This structure describes the following features:
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure.
Description
-
shaderBufferFloat32Atomicsindicates whether shaders can perform 32-bit floating-point load, store and exchange atomic operations on storage buffers. -
shaderBufferFloat32AtomicAddindicates whether shaders can perform 32-bit floating-point add atomic operations on storage buffers. -
shaderBufferFloat64Atomicsindicates whether shaders can perform 64-bit floating-point load, store and exchange atomic operations on storage buffers. -
shaderBufferFloat64AtomicAddindicates whether shaders can perform 64-bit floating-point add atomic operations on storage buffers. -
shaderSharedFloat32Atomicsindicates whether shaders can perform 32-bit floating-point load, store and exchange atomic operations on shared and payload memory. -
shaderSharedFloat32AtomicAddindicates whether shaders can perform 32-bit floating-point add atomic operations on shared and payload memory. -
shaderSharedFloat64Atomicsindicates whether shaders can perform 64-bit floating-point load, store and exchange atomic operations on shared and payload memory. -
shaderSharedFloat64AtomicAddindicates whether shaders can perform 64-bit floating-point add atomic operations on shared and payload memory. -
shaderImageFloat32Atomicsindicates whether shaders can perform 32-bit floating-point load, store and exchange atomic image operations. -
shaderImageFloat32AtomicAddindicates whether shaders can perform 32-bit floating-point add atomic image operations. -
sparseImageFloat32Atomicsindicates whether 32-bit floating-point load, store and exchange atomic operations can be used on sparse images. -
sparseImageFloat32AtomicAddindicates 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.
