VkQueryPoolCreateInfo(3)

C Specification

The VkQueryPoolCreateInfo structure is defined as:

// Provided by VK_VERSION_1_0
typedef struct VkQueryPoolCreateInfo {
    VkStructureType                  sType;
    const void*                      pNext;
    VkQueryPoolCreateFlags           flags;
    VkQueryType                      queryType;
    uint32_t                         queryCount;
    VkQueryPipelineStatisticFlags    pipelineStatistics;
} VkQueryPoolCreateInfo;

Members

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
flags is a bitmask of VkQueryPoolCreateFlagBits
queryType is a VkQueryType value specifying the type of queries managed by the pool.
queryCount is the number of queries managed by the pool.
pipelineStatistics is a bitmask of VkQueryPipelineStatisticFlagBits specifying which counters will be returned in queries on the new pool, as described below in https://registry.khronos.org/vulkansc/specs/1.0-extensions/html/vkspec.html#queries-pipestats. pipelineStatistics is ignored if queryType is not VK_QUERY_TYPE_PIPELINE_STATISTICS.

Description

Valid Usage

VUID-VkQueryPoolCreateInfo-queryType-00791
If the pipelineStatisticsQuery feature is not enabled, queryType must not be VK_QUERY_TYPE_PIPELINE_STATISTICS
VUID-VkQueryPoolCreateInfo-queryType-00792
If queryType is VK_QUERY_TYPE_PIPELINE_STATISTICS, pipelineStatistics must be a valid combination of VkQueryPipelineStatisticFlagBits values

If queryType is VK_QUERY_TYPE_PIPELINE_STATISTICS, pipelineStatistics must not be zero
VUID-VkQueryPoolCreateInfo-queryType-03222
If queryType is VK_QUERY_TYPE_PERFORMANCE_QUERY_KHR, the pNext chain must include a VkQueryPoolPerformanceCreateInfoKHR structure
VUID-VkQueryPoolCreateInfo-queryCount-02763
queryCount must be greater than 0
VUID-VkQueryPoolCreateInfo-queryType-05046
If queryType is VK_QUERY_TYPE_OCCLUSION then queryCount must be less than or equal to the maximum of all VkDeviceObjectReservationCreateInfo::maxOcclusionQueriesPerPool values specified when device was created
VUID-VkQueryPoolCreateInfo-queryType-05047
If queryType is VK_QUERY_TYPE_PIPELINE_STATISTICS then queryCount must be less than or equal to the maximum of all VkDeviceObjectReservationCreateInfo::maxPipelineStatisticsQueriesPerPool values specified when device was created
VUID-VkQueryPoolCreateInfo-queryType-05048
If queryType is VK_QUERY_TYPE_TIMESTAMP then queryCount must be less than or equal to the maximum of all VkDeviceObjectReservationCreateInfo::maxTimestampQueriesPerPool values specified when device was created
VUID-VkQueryPoolCreateInfo-queryType-05049
If queryType is VK_QUERY_TYPE_PERFORMANCE_QUERY_KHR then queryCount must be less than or equal to the maximum of all VkPerformanceQueryReservationInfoKHR::maxPerformanceQueriesPerPool values specified when device was created

Valid Usage (Implicit)

VUID-VkQueryPoolCreateInfo-sType-sType
sType must be VK_STRUCTURE_TYPE_QUERY_POOL_CREATE_INFO
VUID-VkQueryPoolCreateInfo-pNext-pNext
pNext must be NULL or a pointer to a valid instance of VkQueryPoolPerformanceCreateInfoKHR
