Description Timo Aaltonen 2015-12-03 07:42:21 UTC

Hi

A Dell machine can't drive a HDMI output after plugging it in for the second time. I'll let others summarize the status and what makes this hw special.

Comment 1 Gary Wang 2015-12-03 11:35:48 UTC

The HDMI port is designed by Thunderbolt interface with following conditions,

Port-B is for HDMI in Alpine Ridge (Integrated DisplayPort with HDMI/DVI Compatible in VBIOS's VBT).
Port-C is for Type-C in Alpine Ridge (Integrated DisplayPort with HDMI/DVI Compatible in VBIOS's VBT).
Port-D is disabled.

If "Integrated HDMI/DVI" is used for Port-B, this issue went away.

Comment 2 Jim Bride 2015-12-09 22:17:34 UTC

Does anyone have a dmesg capture from the failure that we can be looking at while we wait on receiving hardware?

Comment 3 Timo Aaltonen 2015-12-10 07:57:14 UTC

Sorry, this was due to an older hw revision with old Alpine Ridge. Newer platform with AR B1 doesn't hit the bug.

Comment 4 Timo Aaltonen 2015-12-11 07:41:51 UTC

turns out another config does in fact still suffer from this even with -nightly, so reopening

dmesg dump drm-intel-next-2015-12-04-1+

Here's a dmesg dump from a machine running latest -next plus a test patch by Gary to increase hdmi live status check delay.

Comment 6 Jim Bride 2015-12-11 21:55:21 UTC

I saw a patch from Gary come over the intel-gfx mailing list.  I assume that this patch didn't resolve the issue?

Comment 7 Timo Aaltonen 2015-12-13 07:48:39 UTC

Right, it's the same patch and didn't fix this one.

Comment 8 Gary Wang 2015-12-14 07:19:33 UTC

Wait for Canonical's shipping with customer device C6 sku (with high fail-rate, but low fail-rate in C5 sku w/ 12/9 nightly build) to analyze it.

Comment 9 cprigent 2015-12-15 17:30:34 UTC

Bug scrub:
Decrease importance. It does not block developer work.

no fail for HDMI unplug/re-plugin for 50 test cycles continuity

Hi Timo,
I still cannot reproduce it with drm-intel-nightly 12/15 on C6 sku with HP LP2475w HDMI monitor. 

0/50 fail-rate.

I will try again by several rebooting.

Comment 11 Gary Wang 2015-12-16 09:11:55 UTC

After reboot, it suffered 100% failed when hot-plugin HDMI cable, will provide log soon.

Comment 13 Jim Bride 2015-12-16 18:39:56 UTC

A few things to note from the logs:

Dec 16 04:52:26 u-Precision-5510 kernel: [    1.342758] [drm:intel_csr_ucode_init] Loading i915/skl_dmc_ver1.bin

You'll probably want to look into this and make sure you have the proper DMC firmware available on the system.

Does this platform have an on-board Nvidia GPU?

Dec 16 04:52:26 u-Precision-5510 kernel: [   20.478421] [drm:i915_hotplug_work_func] Connector HDMI-A-1 (pin 5) received hotplug event.
Dec 16 04:52:26 u-Precision-5510 kernel: [   20.478422] [drm:intel_hdmi_detect] [CONNECTOR:44:HDMI-A-1]

We're definitely at least seeing some hot plug activity on the proper HDMI port.

Dec 16 04:52:35 u-Precision-5510 kernel: [   28.865318] [drm:intel_disable_pipe] disabling pipe B

Dec 16 04:52:35 u-Precision-5510 kernel: [   28.867357] [drm:intel_disable_shared_dpll] disabling DPLL 1

...and yet here we are tearing down the pipe that was associated with our HDMI connector.  Eventually we seem to be able to detect the HDMI monitor again, but we have a few other attempts beforehand.  I suspect this (the few failures) is innocuous, but I'm not super familiar with the HDMI code path so I will look into it.  

I have a few questions:

* Has this issue been reproduced more than one time?  Is there a deterministic recipe to reproduce the issue?
* If the issue is reproducible readily, can you reproduce the issue if the Nvidia module is *not* loaded?  I think it's notable that things seemed to go south for us shortly after the Nvidia module was loaded.
* If readily reproducible, can it be reproduced with different monitors?

Comment 14 Timo Aaltonen 2015-12-16 19:08:23 UTC

Yes, it's a hybrid machine, but it should be running in "power saving" mode so not using the dGPU.

My understanding is that it happens every time with this config. Don't know if it has been verified withou nvidia, or with other monitors.

failed log for this issue on 12/17

Hi Jim, I used the latest Gfx SKL firmware for verifying it, the issue was reproduced, please refer the log.

skldmcver123.tar.bz2
sklgucver43.tar.bz2

It could reproduce it by several system rebooting. I only reproduce it with HP LP2475w monitor, and cannot reproduce it with SONY 4k HDMI TV.

I will try to verify it again in xinit mode.

Hi Timo, 
Do you know how to disable nVidia module for test only?

Comment 16 Gary Wang 2015-12-17 08:32:34 UTC

For Jim,
With my HP LP2475w monitor, its fail-rate is about 2/10.

Comment 17 Timo Aaltonen 2015-12-17 15:25:56 UTC

disabling nvidia should be as simple as blacklisting the module in /etc/modprobe.d/...

Comment 18 Jim Bride 2016-01-08 18:48:04 UTC

Any word on whether this reproduces without the Nvidia module loaded?  Were the HDMI patches that Gary submitted sufficient to address this issue?

lack enable-connector and setcrtc for HDMI monitor

Hi Jim,
This issue could be reproduced in 1/17 drm-intel-nightly. In text mode with modeset=1, it appears no fail-rate until now by unplug/re-plug HDMI cable. 

So many probe connector operations in kernel log. It's really strange for me.

When suffering this issue in X-server environment, it seems no obvious error but lack enabling connector and setcrtc for HDMI. please refer following log for do looping in probing HDMI (please refer video in 7z file.)

Lack get resource drm ioctl from usespace

Hi Jim,
This is another fail log about live connection but get edid failed. It seems cannot get edid anymore even unplug/re-plug.

Comment 22 Gary Wang 2016-01-14 04:47:46 UTC

Hi Jim, I forget to summery symptoms for your reference.

For comment #19~#21,
Much HDMI probing operating for each unplug/re-plug then caused HDMI disconnected with symptoms like HDMI’s status being live but read edid failed or edid reading successfully but lacking of initial display from user-space.

Thanks for your help!

Hi Timo,
Because much patch for SKL were merged in upstream i915 and its fail-rate is major decreased. Could you please help to let Canonocal'QA team verify again on the latest drm-intel-nightly? Thanks!

Comment 24 Jani Nikula 2016-06-17 16:51:16 UTC

Timo, uh, this is getting a bit old, still an issue?

Comment 25 Timo Aaltonen 2016-06-19 15:12:51 UTC

I think this was a combination of a vbios and i915 not working together, later bios version allowed bisecting a fix to backport.. fixed in 4.4 and up (237ed86c693d8a)
