VkPhysicalDeviceInvocationMaskFeaturesHUAWEI

The VkPhysicalDeviceInvocationMaskFeaturesHUAWEI structure is defined as:

typedef struct VkPhysicalDeviceInvocationMaskFeaturesHUAWEI {
    VkStructureType sType;
    void* pNext;
    VkBool32 invocationMask;
} VkPhysicalDeviceInvocationMaskFeaturesHUAWEI;

This structure describes the following feature:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• invocationMask indicates that the implementation supports the use of an invocation mask image to optimize the ray dispatch.

If the VkPhysicalDeviceInvocationMaskFeaturesHUAWEI 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 VkPhysicalDeviceInvocationMaskFeaturesHUAWEI, 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.
