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);
