C Specification
To record an execution graph dispatch, call:
// Provided by VK_AMDX_shader_enqueue
void vkCmdDispatchGraphAMDX(
    VkCommandBuffer                             commandBuffer,
    VkDeviceAddress                             scratch,
    VkDeviceSize                                scratchSize,
    const VkDispatchGraphCountInfoAMDX*         pCountInfo);Parameters
- 
commandBufferis the command buffer into which the command will be recorded.
- 
scratchis the address of scratch memory to be used.
- 
scratchSizeis a range in bytes of scratch memory to be used.
- 
pCountInfois 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.
There are no rasterization order guarantees between separately dispatched
graphics nodes, though individual primitives within a single dispatch do
adhere to rasterization order.
Draw calls executed before or after the execution graph also execute
relative to each graphics node with respect to rasterization order.
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 + scratchSize).
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.
This command captures command buffer state for mesh nodes similarly to draw commands.
