## C Specification

The `VkPhysicalDeviceTileShadingFeaturesQCOM` structure is defined as:

    // Provided by VK_QCOM_tile_shading
    typedef struct VkPhysicalDeviceTileShadingFeaturesQCOM {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           tileShading;
        VkBool32           tileShadingFragmentStage;
        VkBool32           tileShadingColorAttachments;
        VkBool32           tileShadingDepthAttachments;
        VkBool32           tileShadingStencilAttachments;
        VkBool32           tileShadingInputAttachments;
        VkBool32           tileShadingSampledAttachments;
        VkBool32           tileShadingPerTileDraw;
        VkBool32           tileShadingPerTileDispatch;
        VkBool32           tileShadingDispatchTile;
        VkBool32           tileShadingApron;
        VkBool32           tileShadingAnisotropicApron;
        VkBool32           tileShadingAtomicOps;
        VkBool32           tileShadingImageProcessing;
    } VkPhysicalDeviceTileShadingFeaturesQCOM;

## Members

This structure describes the following features:

- `tileShading` indicates that the implementation supports tile shading render pass instances.

- `tileShadingFragmentStage` indicates that the implementation supports tile shading in the fragment stage.

- `tileShadingColorAttachments` indicates that the implementation supports access to color attachments in a tile shader.

- `tileShadingDepthAttachments` indicates that the implementation supports access to depth aspect of depth stencil attachments.

- `tileShadingStencilAttachments` indicates that the implementation supports access to stencil aspect of depth stencil attachments.

- `tileShadingInputAttachments` indicates that the implementation supports access to input attachments.

- `tileShadingSampledAttachments` indicates that the implementation supports access to sampling of tile attachments.

- `tileShadingPerTileDraw` indicates that the implementation supports the recording of vkCmdDraw* commands when per-tile execution model is enabled.

- `tileShadingPerTileDispatch` indicates that the implementation supports the recording of `vkCmdDispatch`* commands within those regions of a command buffer where the per-tile execution model is enabled.

- `tileShadingDispatchTile` indicates that the implementation supports the recording of vkCmdDispatchTileQCOM commands.

- `tileShadingApron` indicates that the implementation supports VkRenderPassTileShadingCreateInfoQCOM::`apronSize` value other than (0,0). See Tiling Aprons for more information.

- `tileShadingAnisotropicApron` indicates that the implementation supports VkRenderPassTileShadingCreateInfoQCOM::`apronSize` set to a value where `apronSize`::`width` differs from `apronSize`::`height`.

- `tileShadingAtomicOps` indicates that the implementation supports atomic operations on tile attachment variables.

- `tileShadingImageProcessing` indicates that the implementation supports image processing operations with tile attachments.

## Description

If the `VkPhysicalDeviceTileShadingFeaturesQCOM` structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by `VkPhysicalDeviceTileShadingFeaturesQCOM`, it must add an instance of the structure, with the desired feature members set to `VK_TRUE`, to the `pNext` chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceTileShadingFeaturesQCOM-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_TILE_SHADING_FEATURES_QCOM`
