C Specification

The VkIndirectCommandsLayoutTokenNV structure specifies details to the function arguments that need to be known at layout creation time:

// Provided by VK_EXT_descriptor_heap with VK_NV_device_generated_commands
typedef struct VkIndirectCommandsLayoutPushDataTokenNV {
    VkStructureType    sType;
    const void*        pNext;
    uint32_t           pushDataOffset;
    uint32_t           pushDataSize;
} VkIndirectCommandsLayoutPushDataTokenNV;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • pushDataOffset is the offset used for the push data command.

  • pushDataSize is the size used for the push data command.

Description

If this structure is in the pNext chain of VkIndirectCommandsLayoutTokenNV, and VkIndirectCommandsLayoutTokenNV::tokenType is set to VK_INDIRECT_COMMANDS_TOKEN_TYPE_PUSH_DATA_NV, this structure defines a push data command layout token.

If this structure is not provided, it is equivalent to setting pushDataOffset and pushDataSize to 0.

Valid Usage

  • VUID-VkIndirectCommandsLayoutPushDataTokenNV-pushDataOffset-11335
    The sum of pushDataOffset and pushDataSize must be less than maxPushDataSize

  • VUID-VkIndirectCommandsLayoutPushDataTokenNV-pushDataOffset-11420
    pushDataOffset must be a multiple of 4

  • VUID-VkIndirectCommandsLayoutPushDataTokenNV-pushDataSize-11421
    pushDataSize must be a multiple of 4

Valid Usage (Implicit)
