VkPhysicalDeviceTileShadingPropertiesQCOM

Structure describing properties supported by VK_QCOM_tile_shading

The VkPhysicalDeviceTileShadingPropertiesQCOM structure is defined as:

typedef struct VkPhysicalDeviceTileShadingPropertiesQCOM {
    VkStructureType sType;
    void* pNext;
    uint32_t maxApronSize;
    VkBool32 preferNonCoherent;
    VkExtent2D tileGranularity;
    VkExtent2D maxTileShadingRate;
} VkPhysicalDeviceTileShadingPropertiesQCOM;
  • sType is a VkStructureType value identifying this structure
  • pNext is NULL or a pointer to a structure extending this structure.
  • maxApronSize is the maximum value supported which can be specified for VkRenderPassTileShadingCreateInfoQCOM::apronSize or width and height.
  • 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.
  • 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.
  • 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.
