This is extension, along with related platform exentions, allows
|
|
applications to take exclusive control of displays associated with a native
|
|
windowing system.
|
|
This is especially useful for virtual reality applications that wish to hide
|
|
HMDs (head mounted displays) from the native platform's display management
|
|
system, desktop, and/or other applications.

=== Issues
|
|
|
|
1) Should this extension and its related platform-specific extensions
|
|
leverage `<<VK_KHR_display>>`, or provide separate equivalent interfaces.
|
|
|
|
*RESOLVED*: Use `<<VK_KHR_display>>` concepts and objects.
|
|
`<<VK_KHR_display>>` can be used to enumerate all displays on the system,
|
|
including those attached to/in use by a window system or native platform,
|
|
but `<<VK_KHR_display_swapchain>>` will fail to create a swapchain on in-use
|
|
displays.
|
|
This extension and its platform-specific children will allow applications to
|
|
grab in-use displays away from window systems and/or native platforms,
|
|
allowing them to be used with `<<VK_KHR_display_swapchain>>`.
|
|
|
|
2) Are separate calls needed to acquire displays and enable direct mode?
|
|
|
|
*RESOLVED*: No, these operations happen in one combined command.
|
|
Acquiring a display puts it into direct mode.
