I think the simplest change would be to say API changes SHOULD have
driver-agnostic testcases, with the RFC 2119 meaning of SHOULD:

   SHOULD   This word, or the adjective "RECOMMENDED", mean that there
   may exist valid reasons in particular circumstances to ignore a
   particular item, but the full implications must be understood and
   carefully weighed before choosing a different course.

I.e. s/need/should/. I think it also catches the spirit of the
discussion here; seems like everyone agrees having tests is a good goal.

You'll have to allow for reviewer/maintainer/community discretion no
matter what. Judging by the discussion, CRC based tests don't currently
meet the driver-agnostic requirement. Playing devil's advocate, you
could argue any new APIs couldn't be tested with CRC either, even if it
were the most reasonable approach for i915.


BR,
Jani.
