vkCmdSetEvent(3)

C Specification

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

// Provided by VK_VERSION_1_0
void vkCmdSetEvent(
    VkCommandBuffer                             commandBuffer,
    VkEvent                                     event,
    VkPipelineStageFlags                        stageMask);

Parameters

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.

Description

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

If the geometryShader feature is not enabled, stageMask must not contain VK_PIPELINE_STAGE_GEOMETRY_SHADER_BIT

VUID-vkCmdSetEvent-stageMask-06457
Any pipeline stage included in stageMask must be supported by the capabilities of the queue family specified by the queueFamilyIndex member of the VkCommandPoolCreateInfo structure that was used to create the VkCommandPool that commandBuffer was allocated from, as specified in the table of supported pipeline stages

stageMask must not include VK_PIPELINE_STAGE_HOST_BIT
VUID-vkCmdSetEvent-commandBuffer-01152

VUID-vkCmdSetEvent-commandBuffer-cmdpool
The VkCommandPool that commandBuffer was allocated from must support VK_QUEUE_COMPUTE_BIT, or VK_QUEUE_GRAPHICS_BIT operations
VUID-vkCmdSetEvent-renderpass
This command must only be called outside of a render pass instance
VUID-vkCmdSetEvent-commonparent
Both of commandBuffer, and event must have been created, allocated, or retrieved from the same VkDevice

Host Synchronization

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