getMemoryHostPointerPropertiesEXT :: Device -> ExternalMemoryHandleTypeFlagBits -> ("hostPointer" ::: Ptr ()) -> IO MemoryHostPointerPropertiesEXT Source #

vkGetMemoryHostPointerPropertiesEXT - Get properties of external memory host pointer

Parameters

  • Device is the logical device that will be importing pHostPointer.
  • handleType is the type of the handle pHostPointer.
  • pHostPointer is the host pointer to import from.
  • pMemoryHostPointerProperties is a pointer to a MemoryHostPointerPropertiesEXT structure in which the host pointer properties are returned.

data ImportMemoryHostPointerInfoEXT Source #

VkImportMemoryHostPointerInfoEXT - import memory from a host pointer

Description

Importing memory from a host pointer shares ownership of the memory between the host and the Vulkan implementation. The application can continue to access the memory through the host pointer but it is the application’s responsibility to synchronize device and non-device access to the underlying memory as defined in Host Access to Device Memory Objects.

Applications can import the same underlying memory into multiple instances of Vulkan and multiple times into a given Vulkan instance. However, implementations may fail to import the same underlying memory multiple times into a given physical device due to platform constraints.

Importing memory from a particular host pointer may not be possible due to additional platform-specific restrictions beyond the scope of this specification in which case the implementation must fail the memory import operation with the error code ERROR_INVALID_EXTERNAL_HANDLE_KHR.

The application must ensure that the imported memory range remains valid and accessible for the lifetime of the imported memory object.

VkPhysicalDeviceExternalMemoryHostPropertiesEXT - Structure describing external memory host pointer limits that can be supported by an implementation

Members

The members of the PhysicalDeviceExternalMemoryHostPropertiesEXT structure describe the following implementation-dependent limits:

Description

If the PhysicalDeviceExternalMemoryHostPropertiesEXT structure is included in the pNext chain of PhysicalDeviceProperties2, it is filled with the implementation-dependent limits.
