A marker region can be opened by calling:

void vkCmdDebugMarkerBeginEXT(
    VkCommandBuffer commandBuffer,
    const VkDebugMarkerMarkerInfoEXT* pMarkerInfo);

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.

commandBuffer must be a valid VkCommandBuffer handle

pMarkerInfo must be a valid pointer to a valid VkDebugMarkerMarkerInfoEXT structure

commandBuffer must be in the recording state

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