C Specification

To record an execution graph dispatch, call:

// Provided by VK_AMDX_shader_enqueue
void vkCmdDispatchGraphAMDX(
    VkCommandBuffer                             commandBuffer,
    VkDeviceAddress                             scratch,
    const VkDispatchGraphCountInfoAMDX*         pCountInfo);

Parameters

  • commandBuffer is the command buffer into which the command will be recorded.

  • scratch is a pointer to the scratch memory to be used.

  • pCountInfo is a host pointer to a VkDispatchGraphCountInfoAMDX structure defining the nodes which will be initially executed.

Description

When this command is executed, the nodes specified in pCountInfo are executed. Nodes executed as part of this command are not implicitly synchronized in any way against each other once they are dispatched.

For this command, all device/host pointers in substructures are treated as host pointers and read only during host execution of this command. Once this command returns, no reference to the original pointers is retained.

Execution of this command may modify any memory locations in the range [scratch,scratch + size), where size is the value returned in VkExecutionGraphPipelineScratchSizeAMDX::size by VkExecutionGraphPipelineScratchSizeAMDX for the currently bound execution graph pipeline Accesses to this memory range are performed in the VK_PIPELINE_STAGE_2_COMPUTE_SHADER_BIT pipeline stage with the VK_ACCESS_2_SHADER_STORAGE_READ_BIT and VK_ACCESS_2_SHADER_STORAGE_WRITE_BIT access flags.
