[Mesa-dev] [RFC] add a config file for dri loader to choose a different dri driver

[Yu, Qiang]

So you mean like the xorg way (priority low -> high):
/usr/share/drirc.d/xxx.conf /etc/drirc.d/xxx.conf /etc/drirc ~/.drirc

OK, I'll add this for the ease of driver config.

Regards,
Qiang

If you're going to go down this route, please also teach Mesa to look
for drirc (or drirc.d) under /usr/share first, then /etc. /etc really
is for per-machine configuration, Mesa and driver defaults properly
belong in /usr/share.
