Description

This extension allows the use of the SPV_KHR_maximal_reconvergence SPIR-V extension in shader modules. SPV_KHR_maximal_reconvergence provides stronger guarantees that diverged subgroups will reconverge. These guarantees should match shader author intuition about divergence and reconvergence of invocations based on the structure of the code in the HLL.

Developers should utilize this extension if they require stronger guarantees about reconvergence than either the core spec or SPV_KHR_subgroup_uniform_control_flow. This extension will define the rules that govern how invocations diverge and reconverge in a way that should match developer intuition. It allows robust programs to be written relying on subgroup operations and other tangled instructions.

VkPhysicalDeviceShaderMaximalReconvergenceFeaturesKHR - Structure describing support for shader maximal reconvergence 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. If the application wishes to use a Device with any features described by PhysicalDevicePrivateDataFeaturesEXT, 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.
