Name

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

C Specification

The VkPhysicalDeviceDeviceGeneratedCommandsPropertiesEXT structure is defined as:

// Provided by VK_EXT_device_generated_commands
typedef struct VkPhysicalDeviceDeviceGeneratedCommandsPropertiesEXT {
    VkStructureType                        sType;
    void*                                  pNext;
    uint32_t                               maxIndirectPipelineCount;
    uint32_t                               maxIndirectShaderObjectCount;
    uint32_t                               maxIndirectSequenceCount;
    uint32_t                               maxIndirectCommandsTokenCount;
    uint32_t                               maxIndirectCommandsTokenOffset;
    uint32_t                               maxIndirectCommandsIndirectStride;
    VkIndirectCommandsInputModeFlagsEXT    supportedIndirectCommandsInputModes;
    VkShaderStageFlags                     supportedIndirectCommandsShaderStages;
    VkShaderStageFlags                     supportedIndirectCommandsShaderStagesPipelineBinding;
    VkShaderStageFlags                     supportedIndirectCommandsShaderStagesShaderBinding;
    VkBool32                               deviceGeneratedCommandsTransformFeedback;
    VkBool32                               deviceGeneratedCommandsMultiDrawIndirectCount;
} VkPhysicalDeviceDeviceGeneratedCommandsPropertiesEXT;

Members

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
maxIndirectPipelineCount is the maximum number of pipelines passed to vkCreateIndirectExecutionSetEXT.
maxIndirectShaderObjectCount is the maximum number of shader objects passed to vkCreateIndirectExecutionSetEXT. If this value is zero, binding shader objects indirectly is not supported.
maxIndirectSequenceCount is the maximum number of sequences in VkGeneratedCommandsInfoEXT and in VkGeneratedCommandsMemoryRequirementsInfoEXT.
maxIndirectCommandsTokenCount is the maximum number of tokens in VkIndirectCommandsLayoutCreateInfoEXT.
maxIndirectCommandsTokenOffset is the maximum offset in VkIndirectCommandsLayoutTokenEXT.
maxIndirectCommandsIndirectStride is the maximum stream stride in VkIndirectCommandsLayoutCreateInfoEXT.
supportedIndirectCommandsInputModes indicates the supported input modes.
supportedIndirectCommandsShaderStages indicates the stages which can be used to generate indirect commands. Implementations are required to support, at minimum: VK_SHADER_STAGE_VERTEX_BIT, VK_SHADER_STAGE_FRAGMENT_BIT, VK_SHADER_STAGE_COMPUTE_BIT.
supportedIndirectCommandsShaderStagesPipelineBinding indicates the stages which can be used within indirect execution sets for indirectly binding shader stages using pipelines.
supportedIndirectCommandsShaderStagesShaderBinding indicates the stages which can be used within indirect execution sets for indirectly binding shader stages using shader objects.
deviceGeneratedCommandsTransformFeedback indicates whether the implementation supports interactions with VK_EXT_transform_feedback for pipelines not created with VK_PIPELINE_CREATE_2_INDIRECT_BINDABLE_BIT_EXT.
deviceGeneratedCommandsMultiDrawIndirectCount indicates whether the implementation supports COUNT variants of multi-draw indirect tokens.

Description

If the VkPhysicalDeviceDeviceGeneratedCommandsPropertiesEXT 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-VkPhysicalDeviceDeviceGeneratedCommandsPropertiesEXT-sType-sType
sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DEVICE_GENERATED_COMMANDS_PROPERTIES_EXT
