public final class EXTQueueFamilyForeign extends java.lang.Object
This extension defines a special queue family,QUEUE_FAMILY_FOREIGN_EXT
, which can be used to transfer ownership of resources backed by external memory to foreign, external queues. This is similar toQUEUE_FAMILY_EXTERNAL_KHR
, defined inVK_KHR_external_memory
. The key differences between the two are:- The queues represented by
QUEUE_FAMILY_EXTERNAL_KHR
must share the same physical device and the same driver version as the currentVkInstance
.QUEUE_FAMILY_FOREIGN_EXT
has no such restrictions. It can represent devices and drivers from other vendors, and can even represent non-Vulkan-capable devices. - All resources backed by external memory support
QUEUE_FAMILY_EXTERNAL_KHR
. Support forQUEUE_FAMILY_FOREIGN_EXT
is more restrictive. - Applications should expect transitions to/from
QUEUE_FAMILY_FOREIGN_EXT
to be more expensive than transitions to/fromQUEUE_FAMILY_EXTERNAL_KHR
.
