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 VkPhysicalDeviceProperties2, it is filled with the implementation-dependent limits.

Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_PHYSICAL_DEVICE_SUBGROUP_PROPERTIES
Member documentation
- sType – the type of this structure.
- pNext – NULL or a pointer to an extension-specific structure.
- subgroupSize – the default number of invocations in each subgroup. subgroupSize is at least 1 if any of the physical device’s queues support QUEUE_GRAPHICS_BIT or QUEUE_COMPUTE_BIT. subgroupSize is a power-of-two.
- supportedStages – a bitfield of VkShaderStageFlagBits describing the shader stages that subgroup operations are supported in. supportedStages will have the SHADER_STAGE_COMPUTE_BIT bit set if any of the physical device’s queues support QUEUE_COMPUTE_BIT.
- supportedOperations – a bitmask of VkSubgroupFeatureFlagBits specifying the sets of subgroup operations supported on this device. supportedOperations will have the SUBGROUP_FEATURE_BASIC_BIT bit set if any of the physical device’s queues support QUEUE_GRAPHICS_BIT or QUEUE_COMPUTE_BIT.
- quadOperationsInAllStages – a boolean specifying whether quad subgroup operations are available in all stages, or are restricted to fragment and compute stages.
