public class VkPhysicalDeviceSubgroupSizeControlFeaturesEXT
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure describing the subgroup size control features that can be supported by an implementation.
Description

If the VkPhysicalDeviceSubgroupSizeControlFeaturesEXT structure is included in the pNext chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether the feature is supported. VkPhysicalDeviceSubgroupSizeControlFeaturesEXT can also be included in the pNext chain of VkDeviceCreateInfo to enable the feature.

Note

The VkPhysicalDeviceSubgroupSizeControlFeaturesEXT structure was added in version 2 of the VK_EXT_subgroup_size_control extension. Version 1 implementations of this extension will not fill out the features structure but applications may assume that both subgroupSizeControl and computeFullSubgroups are supported if the extension is supported. (See also the Feature Requirements section.) Applications are advised to add a VkPhysicalDeviceSubgroupSizeControlFeaturesEXT structure to the pNext chain of VkDeviceCreateInfo to enable the features regardless of the version of the extension supported by the implementation. If the implementation only supports version 1, it will safely ignore the VkPhysicalDeviceSubgroupSizeControlFeaturesEXT structure.

Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_PHYSICAL_DEVICE_SUBGROUP_SIZE_CONTROL_FEATURES_EXT
Member documentation
- subgroupSizeControl – indicates whether the implementation supports controlling shader subgroup sizes via the PIPELINE_SHADER_STAGE_CREATE_ALLOW_VARYING_SUBGROUP_SIZE_BIT_EXT flag and the VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT structure.
- computeFullSubgroups – indicates whether the implementation supports requiring full subgroups in compute shaders via the PIPELINE_SHADER_STAGE_CREATE_REQUIRE_FULL_SUBGROUPS_BIT_EXT flag.

     VkStructureType sType;
