Export NvSciSync from Vulkan SC
In the Vulkan SC Specification, VK_NV_external_sci_sync2 defines a feature to export an
NvSciSyncObj
. In Vulkan SC terminology, “export” indicates the
Vulkan SC driver allocates and manages the NvSciSyncObj
instead of
application. To keep the interfaces symmetrical with other NVIDIA DRIVE® OS
UMDs, this feature is always disabled. Applications can use the
vkGetPhysicalDeviceFeatures2
API by passing a
VkPhysicalDeviceExternalSciSync2FeaturesNV
struct to query the enablement
of this feature.
