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. If the application wishes to use a Device with any features described by PhysicalDeviceShaderSubgroupUniformControlFlowFeaturesKHR, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.
