C Specification

The VkPhysicalDevicePerformanceCountersByRegionPropertiesARM structure is defined as:

// Provided by VK_ARM_performance_counters_by_region
typedef struct VkPhysicalDevicePerformanceCountersByRegionPropertiesARM {
    VkStructureType    sType;
    void*              pNext;
    uint32_t           maxPerRegionPerformanceCounters;
    VkExtent2D         performanceCounterRegionSize;
    uint32_t           rowStrideAlignment;
    uint32_t           regionAlignment;
    VkBool32           identityTransformOrder;
} VkPhysicalDevicePerformanceCountersByRegionPropertiesARM;

Members

The members of the VkPhysicalDevicePerformanceCountersByRegionPropertiesARM structure describe the following:

Description

  • maxPerRegionPerformanceCounters is the maximum number of performance counters that can be captured per region.

  • performanceCounterRegionSize is the width and height of each region for which performance counters can be captured.

  • rowStrideAlignment indicates the minimum row alignment for by region counters.

  • regionAlignment indicates the alignment between each region’s counter values.

  • identityTransformOrder is a boolean value indicating whether per region counters are output in framebuffer-space order.

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