# VkPhysicalDeviceDeviceGeneratedCommandsPropertiesNV(3) Manual Page

## Name

VkPhysicalDeviceDeviceGeneratedCommandsPropertiesNV - Structure describing push descriptor limits that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceDeviceGeneratedCommandsPropertiesNV` structure is defined as:

    // Provided by VK_NV_device_generated_commands
    typedef struct VkPhysicalDeviceDeviceGeneratedCommandsPropertiesNV {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           maxGraphicsShaderGroupCount;
        uint32_t           maxIndirectSequenceCount;
        uint32_t           maxIndirectCommandsTokenCount;
        uint32_t           maxIndirectCommandsStreamCount;
        uint32_t           maxIndirectCommandsTokenOffset;
        uint32_t           maxIndirectCommandsStreamStride;
        uint32_t           minSequencesCountBufferOffsetAlignment;
        uint32_t           minSequencesIndexBufferOffsetAlignment;
        uint32_t           minIndirectCommandsBufferOffsetAlignment;
    } VkPhysicalDeviceDeviceGeneratedCommandsPropertiesNV;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `maxGraphicsShaderGroupCount` is the maximum number of shader groups in VkGraphicsPipelineShaderGroupsCreateInfoNV.

- `maxIndirectSequenceCount` is the maximum number of sequences in VkGeneratedCommandsInfoNV and in VkGeneratedCommandsMemoryRequirementsInfoNV.

- `maxIndirectCommandsTokenCount` is the maximum number of tokens in VkIndirectCommandsLayoutCreateInfoNV.

- `maxIndirectCommandsStreamCount` is the maximum number of streams in VkIndirectCommandsLayoutCreateInfoNV.

- `maxIndirectCommandsTokenOffset` is the maximum offset in VkIndirectCommandsLayoutTokenNV.

- `maxIndirectCommandsStreamStride` is the maximum stream stride in VkIndirectCommandsLayoutCreateInfoNV.

- `minSequencesCountBufferOffsetAlignment` is the minimum alignment for memory addresses which can be used in VkGeneratedCommandsInfoNV.

- `minSequencesIndexBufferOffsetAlignment` is the minimum alignment for memory addresses which can be used in VkGeneratedCommandsInfoNV.

- `minIndirectCommandsBufferOffsetAlignment` is the minimum alignment for memory addresses used in VkIndirectCommandsStreamNV, and as preprocess buffer in VkGeneratedCommandsInfoNV.

## Description

If the `VkPhysicalDeviceDeviceGeneratedCommandsPropertiesNV` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceDeviceGeneratedCommandsPropertiesNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DEVICE_GENERATED_COMMANDS_PROPERTIES_NV`
