C Specification
The VkPhysicalDeviceExternalMemorySciBufFeaturesNV
structure is
defined as:
// Provided by VK_NV_external_memory_sci_buf
typedef struct VkPhysicalDeviceExternalMemorySciBufFeaturesNV {
VkStructureType sType;
void* pNext;
VkBool32 sciBufImport;
VkBool32 sciBufExport;
} VkPhysicalDeviceExternalMemorySciBufFeaturesNV;
// Provided by VK_NV_external_memory_sci_buf
typedef VkPhysicalDeviceExternalMemorySciBufFeaturesNV VkPhysicalDeviceExternalSciBufFeaturesNV;
Members
The members of the VkPhysicalDeviceExternalMemorySciBufFeaturesNV
structure describe the following features:
Description
-
sciBufImport
indicates whetherNvSciBufObj
import functionality is supported. IfsciBufImport
is set toVK_TRUE
, VkDeviceMemory supports importingNvSciBufObj
from applications. In this case, the application is responsible for the resource management of theNvSciBufObj
. -
sciBufExport
indicates whetherNvSciBufObj
export functionality is supported. IfsciBufExport
is set toVK_TRUE
, VkDeviceMemory supports exportingNvSciBufObj
created by the driver to applications. In this case, the driver is responsible for the resource management of theNvSciBufObj
.

The Functionality supported for NvSciBuf
features table summarizes the functionality enabled by the
VkPhysicalDeviceExternalMemorySciBufFeaturesNV
structure.
Each entry in the body of the table summarizes the functionality that can
be used when the given features are supported and enabled.
This summarizes Valid Usage statements that are added elsewhere in this
specification.
If the VkPhysicalDeviceExternalMemorySciBufFeaturesNV
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.
VkPhysicalDeviceExternalMemorySciBufFeaturesNV
can also be used in the pNext
chain of
VkDeviceCreateInfo to selectively enable these features.
