[Mesa-dev] [PATCH] EGL/mesa: Initial write up fot MESA_query_driver

[Veluri Mithun]

Hi Everyone,

we can obtain DRM device file from eglQueryDeviceStringEXT fun of
EGL_EXT_device_query extension. But, how to retrieve name, configs from
that?

Can we get the name of the matched driver for a particular display from any
of the EGLDriver->API ?? (EGL API dispatch table)

And looking at x11 implementation of getDrvierConfig, I finally reached
this file
https://gitlab.freedesktop.org/mesa/mesa/blob/master/include/GL/internal/dri_interface.h#L1828
and unable to find the implementation of that getXml function. Can we use
the same function here?

Please let me know what do you think about this.

Thanks,
Veluri.
