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

[Yu, Qiang]

Hi guys,

As previously talked in:
https://lists.freedesktop.org/archives/mesa-dev/2017-April/152055.html

amdgpu-pro driver has interest to adopt the DRI interface to be compatable
with the mesa libgbm. But using MESA_LOADER_DRIVER_OVERRIDE
is not a good way to config OS GFX stack globally, so I'd like to introduce
a /etc/driconf.d/xxx.conf config file to select/overwrite the dri driver like this:
<kernel drm driver name>:<dri driver name>

i.e amdgpu-pro case /etc/driconf.d/amdgpu.conf
amdgpu:amdgpu

Any feedback on this?

Thanks,
Qiang
