VkPhysicalDeviceCoherentMemoryFeaturesAMD(3)

Name

VkPhysicalDeviceCoherentMemoryFeaturesAMD - Structure describing whether device coherent memory can be supported by an implementation

C Specification

The VkPhysicalDeviceCoherentMemoryFeaturesAMD structure is defined as:

// Provided by VK_AMD_device_coherent_memory
typedef struct VkPhysicalDeviceCoherentMemoryFeaturesAMD {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           deviceCoherentMemory;
} VkPhysicalDeviceCoherentMemoryFeaturesAMD;

Members

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.

  • deviceCoherentMemory indicates that the implementation supports device coherent memory.

Description

If the VkPhysicalDeviceCoherentMemoryFeaturesAMD 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 VkPhysicalDeviceCoherentMemoryFeaturesAMD, 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-VkPhysicalDeviceCoherentMemoryFeaturesAMD-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_COHERENT_MEMORY_FEATURES_AMD
