Comment 1 Chris Wilson 2015-08-13 18:23:48 UTC
chv_set_memory_dvfs: *ERROR* timed out waiting for Punit DDR DVFS request
Comment 2 samuel.vonstachelski 2015-08-21 22:55:23 UTC
I got a very similar error:

[drm: valleyview_update_wm [i915_bpol]] *ERROR* timed out waiting for Punit DDR DVFS request

uname -a
Linux 3.19.0-26-generic #28-Ubuntu SMP x86_64

Happens also on Debian Testing.
System: Intel NUC5CPYH
CPU: Celeron N3050
GPU: Intel HD Graphics (Device ID: 22B1)

We have the same error on the exact same machine. Did you find any solutions yet? Did you experience any fatal crashes caused by this bug?

Thanks
Comment 4 Ville Syrjala 2015-08-25 12:02:52 UTC
Sounds like the Punit is unhappy. You should check for a BIOS update first.

Hmm. And the one comment with a kernel version listed is using some Ubuntu frankenkernel. Can anyone reproduce the problems with upstream 4.1 (first one to have official CHV support) or drm-intel-nightly?
Comment 5 Chris Wilson 2015-08-25 12:15:32 UTC
Mine was on -nightly on the braswell nuc.
Comment 6 Chris Wilson 2015-08-25 12:16:04 UTC
It is also apparent on every kernel since circa 4.0 that I have successfully booted on that machine.

Does it still happen with current nightly? The way we did it with 4.1 was to just keep disabling dvfs every time, but with the current code we shouldn't ask the Punit to do anything if the current state is already correct, so that might make the Punit happier.
Comment 8 lhaond 2015-09-06 10:49:28 UTC
Hello,

Got the same issue, so i've tried the nightly ( http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/2015-09-03-unstable/ ) on a Debian Unstable : Linux 4.2.0-994-generic #201509030156 SMP Thu Sep 3 01:58:34 UTC 2015 x86_64 GNU/Linux

Running on asrock N3150-ITX BIOS 1.20 (last bios version available) :

Hello,

Got the same issue, so i've tried the nightly ( http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/2015-09-03-unstable/ ) on a Debian Unstable : Linux 4.2.0-994-generic #201509030156 SMP Thu Sep 3 01:58:34 UTC 2015 x86_64 GNU/Linux

Running on asrock N3150-ITX BIOS 1.20 (last bios version available) :

Does your kernel have the fix listed above?

I.e. are you running v4.3 or later?
Comment 15 Peio Azkarate 2016-02-10 16:52:54 UTC
I've similar error on dmesg.  
Also, the screen gets black for a few seconds sporadically. 

HW information:
Asrock N3150B-ITX (N3150 processor)

SW information:
Fails on Ubuntu 14.04/15.04/15.10

How can I update my drm/i915 driver with the Jani Nikula patch ?

GPU crash dump

Hi guys

I have the same issue here, plus I got a GPU Hang. Hopefully I saved the dump so I'm more than happy to share It with you guys.

This system is quite unstable here. First because of a kernel bug I have to set the status to C1 on this machine, if not the system will hang after few minutes

https://bugzilla.kernel.org/show_bug.cgi?id=109051

now the gpu is misbehaving showing corrupted graphics and spontaneous failures like these reported in this bug.

I hope that the info that I'm attaching could help you.

GPU crash dump

since yesterday I did some changes to the system to discard reporting an error that It is already fixed.

First of all I updated the system with the latest bios from Asrock (released just few days ago) 1.70

http://www.asrock.com/nettop/Intel/Beebox%20Series/?Model=N3000-NUC&cat=Download&os=BIOS

Second, I updated all the X.org packages to the latest version using the latest versions available:

xf86-video-intel-2.99.917-162.1.x86_64
libdrm_intel1-2.4.67-189.1.x86_64
intel-gpu-tools-1.14-54.1.x86_64
ucode-intel-20150121-3.3.x86_64
vaapi-intel-driver-1.6.2-37.3.x86_64

repo URL

http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_Leap_42.1/

With this new setup It is harder to reproduce, but after 2 hours of intensive use I got It reproduced.

Attached file contains dump + system information.

GPU hang dump + system information after flashing bios to 1.70 + updating all the X.org related files to the latest version available
Comment 21 Ville Syrjala 2016-04-12 18:08:59 UTC
Please don't mix up different issues in one bug. A new bug should be filed for the GPU hangs.

Marking this as fixed again.
Comment 22 Marcos Truchado 2016-04-12 19:11:39 UTC
Sorry, I got distracted because I got the cpu hang right after the issue that we are discussing here, hence I thought that It was somehow related. Thanks for confirming that It is not related, I will reorganize this bug and open a new one for the cpu hang.
