## Name

vkCmdSetPerformanceStreamMarkerINTEL - Markers

Loading… please wait.

## C Specification

When monitoring the behavior of an application within the dataset generated by the entire set of applications running on the system, it is useful to identify draw calls within a potentially huge amount of performance data. To do so, application can generate stream markers that will be used to trace back a particular draw call with a particular performance data item.

    // Provided by VK_INTEL_performance_query
    VkResult vkCmdSetPerformanceStreamMarkerINTEL(
        VkCommandBuffer                             commandBuffer,
        const VkPerformanceStreamMarkerInfoINTEL*   pMarkerInfo);

## Parameters

- `commandBuffer` is a VkCommandBuffer into which a stream marker is added.

- `pMarkerInfo` is a pointer to a VkPerformanceStreamMarkerInfoINTEL structure describing the marker to insert.

## Description

Valid Usage (Implicit)

- VUID-vkCmdSetPerformanceStreamMarkerINTEL-commandBuffer-parameter
  `commandBuffer` must be a valid VkCommandBuffer handle

- VUID-vkCmdSetPerformanceStreamMarkerINTEL-pMarkerInfo-parameter
  `pMarkerInfo` must be a valid pointer to a valid VkPerformanceStreamMarkerInfoINTEL structure

- VUID-vkCmdSetPerformanceStreamMarkerINTEL-commandBuffer-recording
  `commandBuffer` must be in the recording state

- VUID-vkCmdSetPerformanceStreamMarkerINTEL-commandBuffer-cmdpool
  The `VkCommandPool` that `commandBuffer` was allocated from must support graphics, compute, or transfer operations

- VUID-vkCmdSetPerformanceStreamMarkerINTEL-videocoding
  This command must only be called outside of a video coding scope

Host Synchronization

- Host access to `commandBuffer` must be externally synchronized

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