Function Prototype

vkCmdSetEvent

Set an event object to signaled state
primary / secondary
outside
both
graphics / compute / decode / encode
synchronization

To set the state of an event to signaled from a device, call:

void vkCmdSetEvent(
    VkCommandBuffer commandBuffer,
    VkEvent event,
    VkPipelineStageFlags stageMask);
  • commandBuffer is the command buffer into which the command is recorded.
  • event is the event that will be signaled.
  • stageMask specifies the source stage mask used to determine the first synchronization scope.

vkCmdSetEvent behaves identically to vkCmdSetEvent2, except that it does not define an access scope, and must only be used with vkCmdWaitEvents, not vkCmdWaitEvents2.

Valid Usage (Implicit)

VUID-vkCmdSetEvent-event-parameter

Host Synchronization

  • Host access to commandBuffer must be externally synchronized
  • Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized ::
