public class VkPhysicalDeviceSubgroupProperties
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure describing subgroup support for an implementation.
Description

If the VkPhysicalDeviceSubgroupProperties structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to GetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

If supportedOperations includes SUBGROUP_FEATURE_QUAD_BIT, or shaderSubgroupUniformControlFlow is enabled, subgroupSize must be greater than or equal to 4.

Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_PHYSICAL_DEVICE_SUBGROUP_PROPERTIES
Layout
```
 struct VkPhysicalDeviceSubgroupProperties {
     VkStructureType sType();
     void * pNext();
     uint32_t subgroupSize();
     VkShaderStageFlags supportedStages();
     VkSubgroupFeatureFlags supportedOperations();
     VkBool32 quadOperationsInAllStages();
