VkPhysicalDevicePerformanceCountersByRegionPropertiesARM

The VkPhysicalDevicePerformanceCountersByRegionPropertiesARM structure is defined as:

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

pub struct PhysicalDevicePerformanceCountersByRegionPropertiesARM {
    s_type: vk::StructureType,
    p_next: *mut c_void,
    max_per_region_performance_counters: u32,
    performance_counter_region_size: vk::Extent2D,
    row_stride_alignment: u32,
    region_alignment: u32,
    identity_transform_order: vk::Bool32,
}

The members of the VkPhysicalDevicePerformanceCountersByRegionPropertiesARM structure describe the following:

• 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.
