Structures
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 structurepNext
isNULL
or a pointer to a structure extending this structure.-
maxApronSize
is the maximum value supported which can be specified for VkRenderPassTileShadingCreateInfoQCOM::apronSize
orwidth
andheight
. -
preferNonCoherent
indicates that the implementation prefers tile attachments declared in shaders with theNonCoherentTileAttachmentReadQCOM
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 ofTileShadingRateQCOM
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.
