[Mesa-dev] [PATCH] egl/dri2: disambiguate driver name (v2)

[Kai Wasserbäch]

So far the Mesa-internal EGL driver "dri2" returned "DRI2" as its driver
name. This causes confusion, because there is an X11 protocol extension
by the same name. To make matters worse, the protocol extension also has
a newer version called "DRI3", which then can lead a user to the
assumption that DRI3 is not used on the current system, even when it
should. While in truth the "DRI2" shown in the EGL version string refers
to an internal interface in Mesa, that has nothing to do with the X11
protocol extension at all.

This change attempts to make it clearer that the "dri2" name of the Mesa
EGL driver has nothing to do with the X11 protocol extension by
prepending "Mesa-" to the driver name shown in the brackets of the EGL
version string.

See the thread beginning at
<https://lists.freedesktop.org/archives/amd-gfx/2017-October/014544.html>
for the exchange that sparked this patch.

v2:
 - Fix commit message. (Michel Dänzer)
 - Don't capitalise "Mesa" in the driver name. (Eric Engestrom)
