C Specification

The number of shader cores used by a queue can be controlled by adding a VkDeviceQueueShaderCoreControlCreateInfoARM structure to the pNext chain of VkDeviceQueueCreateInfo structures.

The VkDeviceQueueShaderCoreControlCreateInfoARM structure is defined as:

// Provided by VK_ARM_scheduling_controls
typedef struct VkDeviceQueueShaderCoreControlCreateInfoARM {
    VkStructureType    sType;
    void*              pNext;
    uint32_t           shaderCoreCount;
} VkDeviceQueueShaderCoreControlCreateInfoARM;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • shaderCoreCount is the number of shader cores this queue uses.

Description

Queues created without specifying VkDeviceQueueShaderCoreControlCreateInfoARM will default to using all the shader cores available.

Valid Usage

  • VUID-VkDeviceQueueShaderCoreControlCreateInfoARM-shaderCoreCount-09399
    shaderCoreCount must be greater than 0 and less than or equal to the total number of shader cores as reported via VkPhysicalDeviceShaderCoreBuiltinsPropertiesARM::shaderCoreCount

Valid Usage (Implicit)

  • VUID-VkDeviceQueueShaderCoreControlCreateInfoARM-sType-sType
    sType must be VK_STRUCTURE_TYPE_DEVICE_QUEUE_SHADER_CORE_CONTROL_CREATE_INFO_ARM
