Description
This extension allows a shader to perform 16-bit floating-point atomic
operations on buffer and workgroup memory as well as floating-point
atomic minimum and maximum operations on buffer, workgroup, and image
memory. It advertises the SPIR-V AtomicFloat16AddEXT
capability which
allows atomic add operations on 16-bit floating-point numbers and the
SPIR-V AtomicFloat16MinMaxEXT
, AtomicFloat32MinMaxEXT
and
AtomicFloat64MinMaxEXT
capabilities which allow atomic minimum and
maximum operations on floating-point numbers. The supported operations
include OpAtomicFAddEXT
, OpAtomicFMinEXT
and OpAtomicFMaxEXT
.

Issues
1) Should this extension add support for 16-bit image atomics?
RESOLVED: No. While Vulkan supports creating storage images with
FORMAT_R16_SFLOAT
and doing load and store
on them, the data in the shader has a 32-bit representation. Vulkan
currently has no facility for even basic reading or writing such images
using 16-bit float values in the shader. Adding such functionality would
be required before 16-bit image atomics would make sense and is outside
the scope of this extension.

VkPhysicalDeviceShaderAtomicFloat2FeaturesEXT - Structure describing features supported by VK_EXT_shader_atomic_float2
Members
This structure describes the following features:
Description
If the PhysicalDeviceShaderAtomicFloat2FeaturesEXT
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. PhysicalDeviceShaderAtomicFloat2FeaturesEXT
can also be
used in the pNext
chain of DeviceCreateInfo
to
selectively enable these features.
