Seems the mesa driconf infrastructure is just what I need:
https://dri.freedesktop.org/wiki/ConfigurationInfrastructure/
So I can reference the loader_get_dri_config_device_id implementation
for adding loader driver override functionality in /etc/drirc:
<driconf>
<device driver="loader">
<option name="amdgpu" value="amdgpu" />
</device>
</driconf>
Thoughts?
Thanks,
Qiang

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