# VkPhysicalDeviceSubpassShadingPropertiesHUAWEI(3) Manual Page

## Name

VkPhysicalDeviceSubpassShadingPropertiesHUAWEI - Structure describing subpass shading properties supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceSubpassShadingPropertiesHUAWEI` structure is defined as:

    // Provided by VK_HUAWEI_subpass_shading
    typedef struct VkPhysicalDeviceSubpassShadingPropertiesHUAWEI {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           maxSubpassShadingWorkgroupSizeAspectRatio;
    } VkPhysicalDeviceSubpassShadingPropertiesHUAWEI;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `maxSubpassShadingWorkgroupSizeAspectRatio` indicates the maximum ratio between the width and height of the portion of the subpass shading shader workgroup size. `maxSubpassShadingWorkgroupSizeAspectRatio` must be a power-of-two value, and must be less than or equal to max(`WorkgroupSize.x` / `WorkgroupSize.y`, `WorkgroupSize.y` / `WorkgroupSize.x`).

## Description

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

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceSubpassShadingPropertiesHUAWEI-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SUBPASS_SHADING_PROPERTIES_HUAWEI`
