--- Comment #1 from Jason Ekstrand <jason at jlekstrand.net> ---
Yes, the hardware trig functions have some very minor precision problems that
the dEQP tests are sensitive enough to pick up on.  It's fixed on Kaby Lake. 
For older hardware, we have a workaround for this but it's off by default. You
just have to set the INTEL_PRECISE_TRIG environment variable to "true" and they
should pass.
