This CL adds two new extensions:
* EGL_ANGLE_ggp_stream_descriptor:
Introduces a new attribute to CreateWindowSurface. Allows the app
to pass in a stream descriptor to VkCreateSurfaceKHR.
Mirrors VK_GGP_stream_descriptor_surface.
* EGL_ANGLE_swap_with_frame_token:
Introduces a new function 'eglSwapBuffersWithFrameTokenANGLE'. This
allows the app to pass a GGP frame token down to vkQueuePresentKHR.
Mirrors VK_GGP_frame_token.

EGL Extension #??
|
|
|
|
Dependencies
|
|
|
|
This extension is written against the wording of the EGL 1.5
|
|
Specification.
|
|
|
|
Overview
|
|
|
|
This extension allows an application that uses a Google Games
|
|
Platform surface to associate a Google Games Platform frame token
|
|
with an eglSwapBuffers operation.
|
|
|
|
It is based on the Vulkan extension VK_GGP_frame_token.
|
|
|
|
New Types
|
|
|
|
This is a 64-bit unsigned type that represents a GGP frame token.
|
|
|
|
typedef khronos_uint64_t EGLFrameTokenANGLE;
|
|
|
|
New Procedures and Functions
|
|
|
|
EGLBoolean eglSwapBuffersWithFrameTokenANGLE(
|
|
EGLDisplay dpy,
|
|
EGLSurface surface,
|
|
EGLFrameTokenANGLE frametoken);
|
|
|
|
New Tokens
|
|
|
|
None
|
|
|
|
Additions to the EGL 1.5 Specification
|
|
|
|
Add the following to section 3.10.1 "Posting to a Window":
|
|
|
|
A Google Games Platform frame token can be specified when posting a color
|
|
buffer to a window by calling
|
|
|
|
EGLBoolean eglSwapBuffersWithFrameTokenANGLE(
|
|
EGLDisplay dpy,
|
|
EGLSurface surface,
|
|
EGLFrameTokenANGLE frametoken);
|
|
|
|
The behaviour of eglSwapBuffersWithFrameTokenANGLE is identical to that
|
|
of eglSwapBuffers except that the behaviour is undefined when <frametoken>
|
|
is not a valid GgpFrameToken.
|
|
|
|
Issues
|
|
|
|
None yet.
