C Specification

The VkPipelineExecutablePropertiesKHR structure is defined as:

// Provided by VK_KHR_pipeline_executable_properties
typedef struct VkPipelineExecutablePropertiesKHR {
    VkStructureType       sType;
    void*                 pNext;
    VkShaderStageFlags    stages;
    char                  name[VK_MAX_DESCRIPTION_SIZE];
    char                  description[VK_MAX_DESCRIPTION_SIZE];
    uint32_t              subgroupSize;
} VkPipelineExecutablePropertiesKHR;

Members

  • sType is the type of this structure.

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

  • stages is a bitmask of VkShaderStageFlagBits indicating which shader stages (if any) were principally used as inputs to compile this pipeline executable.

  • name is an array of VK_MAX_DESCRIPTION_SIZE char containing a null-terminated UTF-8 string which is a short human readable name for this executable.

  • description is an array of VK_MAX_DESCRIPTION_SIZE char containing a null-terminated UTF-8 string which is a human readable description for this executable.

  • subgroupSize is the subgroup size with which this executable is dispatched.

Description

The stages field may be zero or it may contain one or more bits describing the stages principally used to compile this pipeline. Not all implementations have a 1:1 mapping between shader stages and pipeline executables and some implementations may reduce a given shader stage to fixed function hardware programming such that no executable is available. No guarantees are provided about the mapping between shader stages and pipeline executables and stages should be considered a best effort hint. Because the application cannot rely on the stages field to provide an exact description, name and description provide a human readable name and description which more accurately describes the given pipeline executable.

Valid Usage (Implicit)

  • sType must be VK_STRUCTURE_TYPE_PIPELINE_EXECUTABLE_PROPERTIES_KHR

  • pNext must be NULL
