US 11,232,535 B2 · Systems and methods for using EGL with an OpenGL API and a Vulkan graphics driver

Abstract

A method for using an EGL driver to create a renderable surface for an OpenGL API is provided. The EGL driver and the OpenGL API can be used with a Vulkan graphics driver, a memory, at least one processor, and a module stored in the memory including computer instruction code that is executable by the at least on processor. The method includes creating an EGL display structure; initializing the EGL display structure by querying the Vulkan driver for attributes of a physical display; choosing an EGL configuring matching the provided attributes; and creating the EGL surface. A non-transitory computer readable medium having an EGL driver with computer instruction code that is executable by a processor to create a renderable surface for an OpenGL API is also provided.

A method for using an EGL driver to create a renderable surface for an OpenGL API, the EGL driver and the OpenGL API for use with a Vulkan graphics driver, a memory, at least one processor, and a module stored in the memory including computer instruction code that is executable by the at least one processor, the method comprising:

creating an EGL display structure in response to an eglGetDisplay call from an EGL application;
initializing the EGL display structure in response to an egllnitialize call from the EGL application, by:
calling the Vulkan graphics driver to create a Vulkan surface;
and
querying the Vulkan driver for attributes of the Vulkan surface and a physical display associated with the Vulkan surface;
in response to an eglChooseConfig call from the EGL application, choosing an EGL configuration matching the attributes;
and
creating the EGL surface in response to an eglCreateWindowSurface call from the EGL application.
