    loader: Add an environment variable to override driver name choice.
    
    My vc4 simulator has been implemented so far by having an entrypoint
    claiming to be i965, which was a bit gross.  The simulator would be a lot
    less special if we entered through the vc4 entrypoint like normal, so add
    a loader environment variable to allow the i965 fd to probe as vc4.

Created attachment 129378 [details] [review]
always include unistd.h

The attached patch might fix this.

Out of curiosity, what kind of configuration are you building for?

Second that. Vinson can you get some info about your platforms + configure permutations somewhere in a single place. Having the build log(s) would be amazing ;-)
Comment 3 Vinson Lee 2017-02-09 21:59:21 UTC 
Applied attachment 129378 [details] [review]. The build still fails.
