VkPhysicalDeviceTileShadingPropertiesQCOM

The VkPhysicalDeviceTileShadingPropertiesQCOM structure is defined as:

typedef struct VkPhysicalDeviceTileShadingPropertiesQCOM {
    VkStructureType sType;
    void* pNext;
    uint32_t maxApronSize;
    VkBool32 preferNonCoherent;
    VkExtent2D tileGranularity;
    VkExtent2D maxTileShadingRate;
} VkPhysicalDeviceTileShadingPropertiesQCOM;

pub struct PhysicalDeviceTileShadingPropertiesQCOM {
    s_type: vk::StructureType,
    p_next: *mut c_void,
    max_apron_size: u32,
    prefer_non_coherent: vk::Bool32,
    tile_granularity: vk::Extent2D,
    max_tile_shading_rate: vk::Extent2D,
}

• sType is a VkStructureType value identifying this structure
• pNext is NULL or a pointer to a structure extending this structure.
• LIMITS MAXAPRONSIZE
  maxApronSize is the maximum value supported which can be specified for VkRenderPassTileShadingCreateInfoQCOM::apronSize or width and height.
• LIMITS PREFERNONCOHERENT
  preferNonCoherent indicates that the implementation prefers tile attachments declared in shaders with the NonCoherentTileAttachmentReadQCOM decoration. Use of the decoration may offer performance or power advantages.
• LIMITS TILEGRANULARITY
  tileGranularity provides a guarantee on the granularity of each tile. Each tile will have dimensions that are a multiple of this granularity in width and height.
• LIMITS MAXTILESHADINGRATE
  maxTileShadingRate is the maximum value of TileShadingRateQCOM and must be a power of 2.

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