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.

|
* Revision 2, 2017-05-19 (Tobias Hector)
|
|
- Removed extended memory bind functions to VK_KHR_bind_memory2, added
|
|
dependency on that extension, and device-group-specific structs for
|
|
those functions.
