C Specification

The VkPhysicalDeviceExternalMemoryRDMAFeaturesNV structure is defined as:

// Provided by VK_NV_external_memory_rdma
typedef struct VkPhysicalDeviceExternalMemoryRDMAFeaturesNV {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           externalMemoryRDMA;
} VkPhysicalDeviceExternalMemoryRDMAFeaturesNV;


This structure describes the following feature:


  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • externalMemoryRDMA indicates whether the implementation has support for the VK_MEMORY_PROPERTY_RDMA_CAPABLE_BIT_NV memory property and the VK_EXTERNAL_MEMORY_HANDLE_TYPE_RDMA_ADDRESS_BIT_NV external memory handle type.

If the VkPhysicalDeviceExternalMemoryRDMAFeaturesNV 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. VkPhysicalDeviceExternalMemoryRDMAFeaturesNV can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceExternalMemoryRDMAFeaturesNV-sType-sType
