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 PhysicalDeviceShaderSubgroupUniformControlFlowFeaturesKHR
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. PhysicalDeviceShaderSubgroupUniformControlFlowFeaturesKHR
can also be used in the pNext chain of
DeviceCreateInfo to selectively enable these
features.
