VkPipelineExecutablePropertiesKHR

The VkPipelineExecutablePropertiesKHR structure is defined as:

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;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• stages is a bitmask of zero or more 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 pipeline 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 pipeline executable.
• subgroupSize is the subgroup size with which this pipeline executable is dispatched.

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 pipeline 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.
