# VkPhysicalDeviceShaderCoreBuiltinsPropertiesARM(3) Manual Page

## Name

VkPhysicalDeviceShaderCoreBuiltinsPropertiesARM - Structure describing shader core builtins properties supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceShaderCoreBuiltinsPropertiesARM` structure is defined as:

    // Provided by VK_ARM_shader_core_builtins
    typedef struct VkPhysicalDeviceShaderCoreBuiltinsPropertiesARM {
        VkStructureType    sType;
        void*              pNext;
        uint64_t           shaderCoreMask;
        uint32_t           shaderCoreCount;
        uint32_t           shaderWarpsPerCore;
    } VkPhysicalDeviceShaderCoreBuiltinsPropertiesARM;

## Members

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

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

- `shaderCoreMask` is a bitfield where each bit set represents the presence of a shader core whose ID is the bit position. The highest ID for any shader core on the device is the position of the most significant bit set.

- `shaderCoreCount` is the number of shader cores on the device.

- `shaderWarpsPerCore` is the maximum number of simultaneously executing warps on a shader core.

## Description

If the `VkPhysicalDeviceShaderCoreBuiltinsPropertiesARM` 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-VkPhysicalDeviceShaderCoreBuiltinsPropertiesARM-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_CORE_BUILTINS_PROPERTIES_ARM`
