C Specification

The VkBindIndexBufferIndirectCommandNV structure specifies the input data for the VK_INDIRECT_COMMANDS_TOKEN_TYPE_INDEX_BUFFER_NV token.

// Provided by VK_NV_device_generated_commands
typedef struct VkBindIndexBufferIndirectCommandNV {
    VkDeviceAddress    bufferAddress;
    uint32_t           size;
    VkIndexType        indexType;
} VkBindIndexBufferIndirectCommandNV;

Members

  • bufferAddress specifies a physical address of the VkBuffer used as index buffer.

  • size is the byte size range which is available for this operation from the provided address.

  • indexType is a VkIndexType value specifying how indices are treated. Instead of the Vulkan enum values, a custom uint32_t value can be mapped to an VkIndexType by specifying the VkIndirectCommandsLayoutTokenNV::pIndexTypes and VkIndirectCommandsLayoutTokenNV::pIndexTypeValues arrays.

Description

Valid Usage
  • VUID-VkBindIndexBufferIndirectCommandNV-None-02946
    The buffer’s usage flag from which the address was acquired must have the VK_BUFFER_USAGE_INDEX_BUFFER_BIT bit set

  • VUID-VkBindIndexBufferIndirectCommandNV-bufferAddress-02947
    The bufferAddress must be aligned to the indexType used

  • VUID-VkBindIndexBufferIndirectCommandNV-None-02948
    Each element of the buffer from which the address was acquired and that is non-sparse must be bound completely and contiguously to a single VkDeviceMemory object

Valid Usage (Implicit)
  • VUID-VkBindIndexBufferIndirectCommandNV-indexType-parameter
    indexType must be a valid VkIndexType value
