Description

This extension allows a shader to contain floating-point atomic operations on buffer, workgroup, and image memory. It also advertises the SPIR-V AtomicFloat32AddEXT and AtomicFloat64AddEXT capabilities that allows atomic addition on floating-points numbers. The supported operations include OpAtomicFAddEXT, OpAtomicExchange, OpAtomicLoad and OpAtomicStore.

New Structures

Extending PhysicalDeviceFeatures2, DeviceCreateInfo:
- PhysicalDeviceShaderAtomicFloatFeaturesEXT

New Enum Constants

EXT_SHADER_ATOMIC_FLOAT_EXTENSION_NAME

New SPIR-V Capabilities

AtomicFloat32AddEXT

AtomicFloat64AddEXT

VkPhysicalDeviceShaderAtomicFloatFeaturesEXT - Structure describing features supported by VK_EXT_shader_atomic_float

Members

This structure describes the following features:

Description

If the PhysicalDeviceShaderAtomicFloatFeaturesEXT structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDeviceShaderAtomicFloatFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.
