Source/WebCore:
The WebGL context used by WebXR needs to be using the same GPU
as the headset it is talking to. However, the API allows for the
creation of the WebGL context before initializing the WebXR
session.
For now, assume this will trigger the high-performance GPU
on any dual-GPU system. i.e. when the WebGL is created, look
for the "webXRCompatible" creation attribute and force
the high-power GPU if available.
Test: webxr/high-performance.html
* html/canvas/WebGLRenderingContextBase.h: Export the method to retrieve attributes.
* platform/graphics/GraphicsContextGLAttributes.h: Add a flag for forcing the
high performance gpu.
* platform/graphics/cocoa/GraphicsContextGLOpenGLCocoa.mm:
(WebCore::InitializeEGLDisplay):
(WebCore::GraphicsContextGLOpenGL::GraphicsContextGLOpenGL):
* testing/Internals.cpp: New internals method to check what GPU was requested.
(WebCore::Internals::requestedGPU):
* testing/Internals.h:
* testing/Internals.idl:
LayoutTests:
* webxr/high-performance-expected.txt: Added.
* webxr/high-performance.html: Added.
