| EGL client extension |
| |
| Dependencies |
| |
| Requires EGL_ANGLE_platform_angle_vulkan. |
| |
| Overview |
| |
| This extension enables choosing the SwiftShader Vulkan implementation |
| when it is available. |
| |
| New Types |
| |
| None |
| |
| New Procedures and Functions |
| |
| None |
| |
| New Tokens |
| |
| Accepted as values for the EGL_PLATFORM_ANGLE_TYPE_ANGLE attribute: |
| |
| EGL_PLATFORM_ANGLE_DEVICE_TYPE_SWIFTSHADER_ANGLE 0x3487 |
| |
| Additions to the EGL Specification |
| |
| None. |
| |
| New Behavior |
| |
| When calling eglGetPlatformDisplay: |
| |
| To request a SwiftShader-backed Vulkan implementation with ANGLE, the value |
| of EGL_PLATFORM_ANGLE_TYPE_ANGLE should be EGL_PLATFORM_ANGLE_TYPE_VULKAN_ANGLE |
| and the value of EGL_PLATFORM_ANGLE_DEVICE_TYPE_ANGLE should be |
| EGL_PLATFORM_ANGLE_DEVICE_TYPE_SWIFTSHADER_ANGLE. |
| |
| If EGL_PLATFORM_ANGLE_DEVICE_TYPE_ANGLE is |
| EGL_PLATFORM_ANGLE_DEVICE_TYPE_SWIFTSHADER_ANGLE and |
| EGL_PLATFORM_ANGLE_TYPE_ANGLE is not |
| EGL_PLATFORM_ANGLE_TYPE_VULKAN_ANGLE then an EGL_BAD_ATTRIBUTE |
| error is generated and EGL_NO_DISPLAY is returned. |
| |
| Issues |
