Description

This extension splits OpControlBarrier by exposing two new barrier operations with SPV_EXT_split_barrier:

  • OpControlBarrierArriveEXT - notifies that invocation has arrived here

  • OpControlBarrierWaitEXT - waits on all invocations before proceeding execution

In the Vulkan context, this allows apps to synchronize Subgroup execution flow within a Workgroup without requiring all Subgroups to wait at the arrival condition before proceeding to execute independent work. It also permits synchronizing memory access like other control barriers.

VkPhysicalDeviceShaderSplitBarrierFeaturesEXT - Structure describing the shader split barrier features that can be supported by an implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceShaderSplitBarrierFeaturesEXT 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 PhysicalDeviceShaderSplitBarrierFeaturesEXT, 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.
