## C Specification

The VkPerformanceQuerySubmitInfoKHR structure is defined as:

// Provided by VK_KHR_performance_query
typedef struct VkPerformanceQuerySubmitInfoKHR {
VkStructureType    sType;
const void*        pNext;
uint32_t           counterPassIndex;
} VkPerformanceQuerySubmitInfoKHR;

## Members

• sType is the type of this structure.

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

• counterPassIndex specifies which counter pass index is active.

## Description

If the VkSubmitInfo::pNext chain does not include this structure, the batch defaults to use counter pass index 0.

Valid Usage
• VUID-VkPerformanceQuerySubmitInfoKHR-counterPassIndex-03221
counterPassIndex must be less than the number of counter passes required by any queries within the batch. The required number of counter passes for a performance query is obtained by calling vkGetPhysicalDeviceQueueFamilyPerformanceQueryPassesKHR

Valid Usage (Implicit)
• VUID-VkPerformanceQuerySubmitInfoKHR-sType-sType
sType must be VK_STRUCTURE_TYPE_PERFORMANCE_QUERY_SUBMIT_INFO_KHR
