# vkCmdDebugMarkerBeginEXT(3) Manual Page

## Name

vkCmdDebugMarkerBeginEXT - Open a command buffer marker region

Loading… please wait.

## C Specification

A marker region can be opened by calling:

    // Provided by VK_EXT_debug_marker
    void vkCmdDebugMarkerBeginEXT(
        VkCommandBuffer                             commandBuffer,
        const VkDebugMarkerMarkerInfoEXT*           pMarkerInfo);

## Parameters

- `commandBuffer` is the command buffer into which the command is recorded.

- `pMarkerInfo` is a pointer to a VkDebugMarkerMarkerInfoEXT structure specifying the parameters of the marker region to open.

## Description

Valid Usage

- VUID-vkCmdDebugMarkerBeginEXT-None-10614
  This command must not be recorded when per-tile execution model is enabled

Valid Usage (Implicit)

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

- VUID-vkCmdDebugMarkerBeginEXT-pMarkerInfo-parameter
  `pMarkerInfo` must be a valid pointer to a valid VkDebugMarkerMarkerInfoEXT structure

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

- VUID-vkCmdDebugMarkerBeginEXT-commandBuffer-cmdpool
  The `VkCommandPool` that `commandBuffer` was allocated from must support VK_QUEUE_COMPUTE_BIT, VK_QUEUE_GRAPHICS_BIT, VK_QUEUE_OPTICAL_FLOW_BIT_NV, VK_QUEUE_TRANSFER_BIT, VK_QUEUE_VIDEO_DECODE_BIT_KHR, or VK_QUEUE_VIDEO_ENCODE_BIT_KHR operations

Host Synchronization

- Host access to `commandBuffer` must be externally synchronized

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