vkCmdPipelineBarrier2

To record a pipeline barrier, call:

void vkCmdPipelineBarrier2KHR(
    VkCommandBuffer                   commandBuffer,
    const VkDependencyInfo*                             pDependencyInfo);

commandBuffer is the command buffer into which the command is recorded.
pDependencyInfo is a pointer to a VkDependencyInfo structure defining the scopes of this operation.

When vkCmdPipelineBarrier2 is submitted to a queue, it defines memory dependencies between commands that were submitted to the same queue before it, and those submitted to the same queue after it.

The first synchronization scope and access scope of each memory dependency defined by pDependencyInfo are applied to operations that occurred earlier in submission order.

The second synchronization scope and access scope of each memory dependency defined by pDependencyInfo are applied to operations that occurred later in submission order.

If vkCmdPipelineBarrier2 is recorded within a render pass instance, the synchronization scopes are limited to a subset of operations within the same subpass or render pass instance.
