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 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.
