C Specification

The shader instrumentation metrics block header is defined as:

// Provided by VK_ARM_shader_instrumentation
typedef struct VkShaderInstrumentationMetricDataHeaderARM {
    uint32_t              resultIndex;
    uint32_t              resultSubIndex;
    VkShaderStageFlags    stages;
    uint32_t              basicBlockIndex;
} VkShaderInstrumentationMetricDataHeaderARM;

Members

  • resultIndex is the result index of the metric block, as captured when the command was recorded.

  • resultSubIndex is a secondary index with the result index, explained further below.

  • stages is a bitfield of VkShaderStageFlagBits describing the shader stages that the metric block is for.

  • basicBlockIndex is the index of the basic block within the shader that the metric block is for.

Description

Valid Usage (Implicit)

  • VUID-VkShaderInstrumentationMetricDataHeaderARM-stages-parameter
    stages must be a valid combination of VkShaderStageFlagBits values

  • VUID-VkShaderInstrumentationMetricDataHeaderARM-stages-requiredbitmask
    stages must not be 0
