Debug layers seem to be a universal thing among functional back-ends. D3D, OpenGL and Vulkan all need some kind of controls for debugging, so it seems to make sense to make this control part of the base extension. Default the extension to EGL_DONT_CARE, which allows the back-end to have a lot of flexibility in terms of implementation. Also enable the extension in the D3D11 and OpenGL back-ends, and set the extension to enabled for angle_end2end_tests. Remove EGLVulkanEXTTest since it no longer tests anything not tested in the base ANGLETest class.

Overview
|
|
|
|
This extension enables selection of Vulkan display types.

|
|
New Tokens
|
|
|
|
Accepted as values for the EGL_PLATFORM_ANGLE_TYPE_ANGLE attribute:
|
|
|
|
EGL_PLATFORM_ANGLE_TYPE_VULKAN_ANGLE 0x3450
|
|
|
|
Additions to the EGL Specification
|
|

|
None.
|
|
|
|
New Behavior
|
|
|
|
To request a display that is backed by a Vulkan driver, the value of
|
|
EGL_PLATFORM_ANGLE_TYPE_ANGLE should be
|
|
EGL_PLATFORM_ANGLE_TYPE_VULKAN_ANGLE.
|
|
|
|
If EGL_PLATFORM_ANGLE_MAX_VERSION_MAJOR_ANGLE and
|
|
EGL_PLATFORM_ANGLE_MAX_VERSION_MINOR_ANGLE are not specified, the
|
|
implementation will decide which version of Vulkan to instantiate. If they
|
|
are specified, it will choose a version that is lower or equal to the
|
|
specified major and minor versions. The only current values accepted for
|
|
major and minor version are 1 for major and 0 for minor.
|
|
|
|
Issues
|
|
|
|
1) Should ANGLE always instantiate the highest available version of Vulkan?
|
|
|
|
RESOLVED: It's possible that in a future implementation of Vulkan there
|
|
may be driver issues present only on some version of Vulkan, and there's
|
|
no explicit guarantee higher versions will be more stable. Hence, we should
|
|
give ANGLE some flexiblity in this regard and leave this unspecified.
