1548911 - Fix broken Linux driver vendor detection

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect, P3)

Description

[Andrew Osmond [:aosmond] (he/him)]

There have been some reports of the driver vendor not reporting the correct value. With Wayland, it has been suggested that the following EGL extension can be used to provide the driver information instead of glXGetScreenDriver:

https://www.khronos.org/registry/EGL/extensions/MESA/EGL_MESA_query_driver.txt

Support for this was added in Mesa 19.

Attachment: Bug 1548911 - Add support for EGL_MESA_query_driver to detect Mesa driver.

If Wayland is in use, then glXGetScreenDriver doesn't return the Mesa
driver name. There is a new API, eglGetDisplayDriverName, which was
added in Mesa 19 that works with Wayland.
