public class VkPhysicalDeviceSubgroupSizeControlPropertiesEXT
extends Struct
implements NativeResource
```
Structure describing the control subgroup size properties of an implementation.
Description

If the VkPhysicalDeviceSubgroupSizeControlPropertiesEXT structure is included in the pNext chain of VkPhysicalDeviceProperties2, it is filled with the implementation-dependent limits.

Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_PHYSICAL_DEVICE_SUBGROUP_SIZE_CONTROL_PROPERTIES_EXT
Member documentation
- sType – the type of this structure.
- pNext – NULL or a pointer to an extension-specific structure.
- minSubgroupSize – the minimum subgroup size supported by this device. minSubgroupSize is at least one if any of the physical device’s queues support QUEUE_GRAPHICS_BIT or QUEUE_COMPUTE_BIT. minSubgroupSize is less than or equal to maxSubgroupSize. minSubgroupSize is less than or equal to subgroupSize.
- maxSubgroupSize – the maximum subgroup size supported by this device. maxSubgroupSize is at least one if any of the physical device’s queues support QUEUE_GRAPHICS_BIT or QUEUE_COMPUTE_BIT. maxSubgroupSize is greater than or equal to minSubgroupSize. maxSubgroupSize is greater than or equal to subgroupSize.
- maxComputeWorkgroupSubgroups – the maximum number of subgroups supported by the implementation within a workgroup.
- requiredSubgroupSizeStages – a bitfield of what shader stages support having a required subgroup size specified.
