public class VkPhysicalDeviceSubgroupProperties extends org.lwjgl.system.Struct<VkPhysicalDeviceSubgroupProperties> 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.
