VkPhysicalDeviceShaderTileImagePropertiesEXT

The VkPhysicalDeviceShaderTileImagePropertiesEXT structure is defined as:

typedef struct VkPhysicalDeviceShaderTileImagePropertiesEXT {
    VkStructureType sType;
    void* pNext;
    VkBool32 shaderTileImageCoherentReadAccelerated;
    VkBool32 shaderTileImageReadSampleFromPixelRateInvocation;
    VkBool32 shaderTileImageReadFromHelperInvocation;
} VkPhysicalDeviceShaderTileImagePropertiesEXT;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• shaderTileImageCoherentReadAccelerated is a boolean that will be VK_TRUE if coherent reads of tile image data is accelerated.
• shaderTileImageReadSampleFromPixelRateInvocation is a boolean that will be VK_TRUE if reading from samples from a pixel rate fragment invocation is supported when VkPipelineMultisampleStateCreateInfo::rasterizationSamples > 1.
• shaderTileImageReadFromHelperInvocation is a boolean that will be VK_TRUE if reads of tile image data from helper fragment invocations result in valid values.

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

These are properties of the tile image information of a physical device.
