    gallium: move driinfo XML to pipe_loader
    
    We will switch to the pipe_loader loading the configuration options,
    so that they can be passed to the driver independently of the state
    tracker.
    
    Put the description into its own file so that it can be merged easily
    with driver-specific options in future commits.

Comment 1 Nicolai Hähnle 2017-11-15 13:41:48 UTC

I cannot reproduce this on Mesa master by running:

$ GALLIUM_DRIVER=softpipe LIBGL_ALWAYS_SOFTWARE=true ./bin/fdo10370 -auto

What am I missing?

Comment 2 Mark Janes 2017-11-21 23:33:19 UTC

Removing from the tracker, since it couldn't be easily reproduced.
