C Specification

The VkIndirectCommandsIndexBufferTokenEXT structure specifies the layout token info for the VK_INDIRECT_COMMANDS_TOKEN_TYPE_INDEX_BUFFER_EXT token.

// Provided by VK_EXT_device_generated_commands
typedef struct VkIndirectCommandsIndexBufferTokenEXT {
    VkIndirectCommandsInputModeFlagBitsEXT    mode;
} VkIndirectCommandsIndexBufferTokenEXT;

Members

  • mode specifies the mode to use with this token.

Description

This allows for easy layering of Vulkan atop other APIs. When VK_INDIRECT_COMMANDS_INPUT_MODE_DXGI_INDEX_BUFFER_EXT is specified, the indirect buffer can contain a D3D12_INDEX_BUFFER_VIEW instead of VkBindIndexBufferIndirectCommandEXT as D3D’s DXGI format value is mapped to the VkIndexType. It works as both structs are otherwise binary compatible.

Valid Usage
  • VUID-VkIndirectCommandsIndexBufferTokenEXT-mode-11135
    mode must be non-zero

  • VUID-VkIndirectCommandsIndexBufferTokenEXT-mode-11136
    mode must be one of the bits supported in VkPhysicalDeviceDeviceGeneratedCommandsPropertiesEXT::supportedIndirectCommandsInputModes

Valid Usage (Implicit)
