## Name

VkDispatchGraphInfoAMDX - Structure specifying node parameters for execution graph dispatch

Loading… please wait.

## C Specification

The `VkDispatchGraphInfoAMDX` structure is defined as:

    // Provided by VK_AMDX_shader_enqueue
    typedef struct VkDispatchGraphInfoAMDX {
        uint32_t                          nodeIndex;
        uint32_t                          payloadCount;
        VkDeviceOrHostAddressConstAMDX    payloads;
        uint64_t                          payloadStride;
    } VkDispatchGraphInfoAMDX;

## Members

- `nodeIndex` is the index of a node in an execution graph to be dispatched.

- `payloadCount` is the number of payloads to dispatch for the specified node.

- `payloads` is a device or host address pointer to a flat array of payloads with size equal to the product of `payloadCount` and `payloadStride`

- `payloadStride` is the byte stride between successive payloads in `payloads`

## Description

Whether `payloads` is consumed as a device or host pointer is defined by the command this structure is used in.

Valid Usage

- VUID-VkDispatchGraphInfoAMDX-payloadCount-09171
  `payloadCount` must be no greater than `maxExecutionGraphShaderPayloadCount`
