Description
This extension allows the use of the
SPV_KHR_subgroup_uniform_control_flow
SPIR-V extension in shader
modules. SPV_KHR_subgroup_uniform_control_flow
provides stronger
guarantees that diverged subgroups will reconverge.
Developers should utilize this extension if they use subgroup operations to reduce the work performed by a uniform subgroup. This extension will guarantee that uniform subgroup will reconverge in the same manner as invocation groups (see “Uniform Control Flow” in the Khronos SPIR-V Specification).

data PhysicalDeviceShaderSubgroupUniformControlFlowFeaturesKHR Source #
VkPhysicalDeviceShaderSubgroupUniformControlFlowFeaturesKHR - Structure describing support for shader subgroup uniform control flow by an implementation
Members
This structure describes the following feature:
Description
If the
PhysicalDevicePrivateDataFeaturesEXT
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.
PhysicalDevicePrivateDataFeaturesEXT
can also be used in the pNext
chain of
DeviceCreateInfo
to selectively enable these
features.
