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).

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.
