This extension provides functionality to use a logical device that consists
|
|
of multiple physical devices, as created with the
|
|
+VK_KHX_device_group_creation+ extension.
|
|
A device group can allocate memory across the subdevices, bind memory from
|
|
one subdevice to a resource on another subdevice, record command buffers
|
|
where some work executes on an arbitrary subset of the subdevices, and
|
|
potentially present a swapchain image from one or more subdevices.
