--- Comment #6 from wendy.wang at intel.com ---
We do have igt test to cover PC6.
Run the latest version of igt pm_rc6_residency case, the result is PASS.
IGT-Version: 1.6-gd71add5 (x86_64) (Linux:
3.15.0-rc3_drm-intel-nightly_f79ba7_20140519+ x86_64)

Test pc6 using turbostat tool, still did not see Baytrail enter PC6.
Kernel:Linux x-byt06 3.15.0-rc3_drm-intel-nightly_f79ba7_20140519+ #2774 SMP
