--- Comment #4 from Eero Tamminen <eero.t.tamminen at intel.com> ---
If you have a working Apitrace trace, ezBench could be used to automatically
bisect which Mesa commits cause changes in rendering i.e. regresses it.

ezBench is here:
  https://cgit.freedesktop.org/ezbench

You need to set up "user_parameters.sh" file so that ezBench can build Mesa &
run it with Apitrace, and have a folder with the apitrace trace file used for
render validation + a file which tells which frame in the trace is used for
comparison.

README tells how to setup & use ezBench.  I will add some documentation on how
to do the Apitrace validation (to the example parameter file).
