Comment 4 Paulo Zanoni 2014-10-08 18:36:09 UTC 
Hi

This bug report is very confusing since it started as "BYT/BSW have WARNs when booting", but then it also got reports from BDW IGT tests. I really suggest that, on this bug report, we completely ignore IGT and focus on the "we get WARNs when booting BYT/BSW": any IGT problems that don't happen when booting should be considered as another bug.

In addition, I believe the BDW part was fixed by "drm/i915: properly reenable gen8 pipe IRQs". So, can you please retest BYT/BDW/BSW and tell me on which platforms you still see WARNs when booting?

Thanks,
Paulo

Clean boot system, the warning goes away.
Run kms_flip case still has warning. We will report a bug about igt case and close this bug.
Comment 6 lu hua 2014-10-13 06:19:23 UTC 
Test on latest on latest -nightly kernel. Clean boot system and run above kms_flip/kms_cursor_crc cases, they work well on BDW. on BYT, they have bug 73037.
Close it.
Comment 7 lu hua 2014-10-13 06:19:36 UTC 
Verified.Fixed.
Comment 8 Jari Tahvanainen 2016-09-28 13:28:33 UTC
