VkPhysicalDeviceAntiLagFeaturesAMD

Structure describing whether VK_AMD_anti_lag can be supported by an implementation.

The VkPhysicalDeviceAntiLagFeaturesAMD structure is defined as:

typedef struct VkPhysicalDeviceAntiLagFeaturesAMD {
    VkStructureType sType;
    void* pNext;
    VkBool32 antiLag;
} VkPhysicalDeviceAntiLagFeaturesAMD;

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.
  • antiLag indicates whether the implementation supports AMD Radeon™ Anti-Lag functionality. The antiLag feature only supports a single GPU and must not be enabled if VkDeviceGroupDeviceCreateInfo::physicalDeviceCount is greater than 1.

If the VkPhysicalDeviceAntiLagFeaturesAMD 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 VkPhysicalDeviceAntiLagFeaturesAMD, 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-VkPhysicalDeviceAntiLagFeaturesAMD-sType-sType

sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_ANTI_LAG_FEATURES_AMD
