VkPhysicalDeviceShaderSplitBarrierPropertiesEXT(3)

# VkPhysicalDeviceShaderSplitBarrierPropertiesEXT(3) Manual Page

## Name

VkPhysicalDeviceShaderSplitBarrierPropertiesEXT - Structure describing split barrier properties supported by an implementation

## C Specification

The `VkPhysicalDeviceShaderSplitBarrierPropertiesEXT` structure is defined as:

    // Provided by VK_EXT_shader_split_barrier
    typedef struct VkPhysicalDeviceShaderSplitBarrierPropertiesEXT {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           splitBarrierReservedSharedMemory;
    } VkPhysicalDeviceShaderSplitBarrierPropertiesEXT;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `splitBarrierReservedSharedMemory` is the number of bytes of shared memory reserved for the implementation when the module executes `OpControlBarrierArriveEXT` or `OpControlBarrierWaitEXT` instructions

## Description

If the `VkPhysicalDeviceShaderSplitBarrierPropertiesEXT` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceShaderSplitBarrierPropertiesEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SPLIT_BARRIER_PROPERTIES_EXT

Structure Chaining

Extends the structure

  - VkPhysicalDeviceProperties2
