Could you please check why rtcwake fails? You can check if S3 is supported at all on your platform by cat /sys/power/state.

I confirm that S3 works on my platform, i'll investigate why rtcwake is fails

> This issue still happen on KBL with the following configuration

BXT was failing due to a configuration error, are you suggesting that KBL fails in exactly the same way?
Comment 5 cprigent 2016-04-01 15:11:56 UTC 
Updated to highest blocker as gem_exec_suspend@basic-s3 and basic-s4 fail on APL.
Comment 6 cprigent 2016-04-07 08:39:18 UTC 
Hi Humberto,
If still reproduced, could you attach the logs of the Basic failures on APL.
Thanks

Comment 8 Chris Wilson 2016-04-07 20:10:09 UTC 
That's the same configuration error assert. We don't think that is a bug in the kernel or test, but in your setup.
Comment 9 cprigent 2016-04-13 17:54:23 UTC 
Checked again. basic-s3 and basic-s4 are no more failing on APL.
Priority and severity decreased. Tested with:

Error "This failure means that something is wrong with the rtcwake tool or how your distro is set up. This is not a i915.ko or i-g-t bug." could come from the date which is probably in the past.
You can retry again after executing:

So, S3 and S4 works fine (BSW-N3050) without issuing batch commands to the GPU. 

The BXT seem to have some FIFO underrun before trying to issue a GPU reset.
Comment 27 Mika Kuoppala 2016-06-13 10:34:56 UTC 
With kbl this test passes, (skipped all s4 ones).
Comment 28 Mika Kuoppala 2016-06-13 13:40:27 UTC 
With our bxt this test passes, (skipped all s4 ones).

Please retest

Comment 31 Chris Wilson 2016-06-14 10:12:01 UTC 
The GPU hangs were after S4. If they are being skipped, that is not a fix.
Comment 32 yann 2016-06-14 11:50:22 UTC 
Christophe do you have any GPU hang on either KBL & APL?

BTW, I am seeing a reference to a GPU Hang on gen8 (on BSW) not on gen9.
Comment 33 Marius Vlad 2016-06-14 12:39:29 UTC 
Yes, that is correct. gen8. Maybe I should file another bug for that?
Comment 34 yann 2016-06-14 12:47:10 UTC 
Yes, fill another bug to track this GPU Hang on BSW
Comment 35 cprigent 2016-06-15 13:58:12 UTC 
No GPU Hang on APL or KBL.
I update title and remove BXT and KBL from i915 platform field.
Comment 36 Humberto Israel Perez Rodriguez 2016-07-04 18:26:24 UTC 
with the following configuration no GPU hang was seen on BSW

from the family "gem_exec_suspend" this tests was skipped

GPU Hang on BSW is tracked by bug 96526.
I just reproduced it on APL. I commented same bug. Let's close bug 94597.
