C Specification

To end an indexed query after the set of desired draw or dispatch commands is recorded, call:

void vkCmdEndQueryIndexedEXT(
    VkCommandBuffer                             commandBuffer,
    VkQueryPool                                 queryPool,
    uint32_t                                    query,
    uint32_t                                    index);

Parameters

  • commandBuffer is the command buffer into which this command will be recorded.

  • queryPool is the query pool that is managing the results of the query.

  • query is the query index within the query pool where the result is stored.

  • index is the query type specific index.

Description

The vkCmdEndQueryIndexedEXT command operates the same as the vkCmdEndQuery command, except that it also accepts a query type specific index parameter.

Valid Usage
  • All queries used by the command must be active

  • query must be less than the number of queries in queryPool

  • commandBuffer must not be a protected command buffer

  • If vkCmdEndQueryIndexedEXT is called within a render pass instance, the sum of query and the number of bits set in the current subpass’s view mask must be less than or equal to the number of queries in queryPool

  • If the queryType used to create queryPool was VK_QUERY_TYPE_TRANSFORM_FEEDBACK_STREAM_EXT the index parameter must be less than VkPhysicalDeviceTransformFeedbackPropertiesEXT::maxTransformFeedbackStreams

  • If the queryType used to create queryPool was not VK_QUERY_TYPE_TRANSFORM_FEEDBACK_STREAM_EXT the index must be zero

  • If the queryType used to create queryPool was VK_QUERY_TYPE_TRANSFORM_FEEDBACK_STREAM_EXT index must equal the index used to begin the query

Valid Usage (Implicit)
  • commandBuffer must be a valid VkCommandBuffer handle

  • queryPool must be a valid VkQueryPool handle

  • commandBuffer must be in the recording state

  • The VkCommandPool that commandBuffer was allocated from must support graphics, or compute operations

  • Both of commandBuffer, and queryPool must have been created, allocated, or retrieved from the same VkDevice

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

  • Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
