Hi Linus,
I Was Almost Tempted To Capitalise Every Word, but then I decided I
couldn't read it myself!
There are some conflicts with your tree in MAINTAINERS, i915 and amdgpu,
they are all fairly trivial, I've pushed a drm-next-merged branch if you
want to check anything out.
I've also got one pull request for the sti driver outstanding. It relied
on a commit in Greg's tree and I didn't find out in time, that commit is
in your tree now so I might send that along once this is merged.
I also had the accidental misfortune to have access to a Skylake on my
desk for a few days, and I've had to encourage Intel to try harder, which
seems to be happening now.
Here is the main drm-next pull request for 4.4.
Highlights:
New driver:
vc4 driver for the Rasberry Pi VPU.
(From Eric Anholt at Broadcom.)
Core:
Atomic fbdev support
Atomic helpers for runtime pm

[...]
This patch seems to introduce a regression for i915 in Linus'
v4.4-rc4-60-g9a0f76f, relative to v4.3 (and 4.3.1), on a sandy-bridge
(Intel DH67CL) system with a single HDMI connected monitor (Medion MD20094)
attached. Immediately after the modeswitch, the monitor switches off and
stays off. Nothing catches my eyes in dmesg or Xorg.0.log, but bisecting
the issue points me at:
237ed86c693d8a8e4db476976aeb30df4deac74b is the first bad commit

drm/i915: Check live status before reading edid
The Bspec is very clear that Live status must be checked about before
trying to read EDID over DDC channel. This patch makes sure that HDMI
EDID is read only when live status is up.
The live status doesn't seem to perform very consistent across various
platforms when tested with different monitors. The reason behind that is
some monitors are late to provide right voltage to set live_status up.
So, after getting the interrupt, for a small duration, live status reg
fluctuates, and then settles down showing the correct staus.
This is explained here in, in a rough way:
HPD line ________________
|\ T1 = Monitor Hotplug causing IRQ
| \______________________________________
| |
| |
| | T2 = Live status is stable
| | _____________________________________
| | /|
Live status _____________|_|/ |
| | |
| | |
| | |
T0 T1 T2
(Between T1 and T2 Live status fluctuates or can be even low, depending on
the monitor)
After several experiments, we have concluded that a max delay
of 30ms is enough to allow the live status to settle down with
most of the monitors. This total delay of 30ms has been split into
a resolution of 3 retries of 10ms each, for the better cases.
This delay is kept at 30ms, keeping in consideration that, HDCP compliance
expect the HPD handler to respond a plug out in 100ms, by disabling port.
v2: Adding checks for VLV/CHV as well. Reusing old ibx and g4x functions
to check digital port status. Adding a separate function to get bxt live
status (Daniel)
v3: Using intel_encoder->hpd_pin to check the live status (Siva)
Moving the live status read to intel_hdmi_probe and passing parameter
to read/not to read the edid. (me)
v4:
* Added live status check for all platforms using
intel_digital_port_connected.
* Rebased on top of Jani's DP cleanup series
* Some monitors take time in setting the live status. So retry for few
times if this is a connect HPD
v5: Removed extra "drm/i915" from commit message. Adding Shashank's sob
which was missed.
v6: Drop the (!detect_edid && !live_status check) check because for DDI
ports which are enumerated as hdmi as well as DP, we don't have a
mechanism to differentiate between DP and hdmi inside the encoder's
hot_plug. This leads to call to the hdmi's hot_plug hook for DP as well
as hdmi which leads to issues during unplug because of the above check.
v7: Make intel_digital_port_connected global in this patch, some
reformatting of while loop, adding a print when live status is not
up. (Rodrigo)
v8: Rebase it on nightly which involved skipping the hot_plug hook for now
and letting the live_status check happen in detect until the hpd handling
part is finalized (Daniel)

Unfortunately reverting only this patch on top of v4.4-rc4-60-g9a0f76f
doesn't appear to be quite straight forward. What is the best approach
to debug this further?
The very same kernel works fine on two ivy-bridge systems (different
monitors, one connected via HDMI, one via DVI) and an Atom N270 based
system (Intel D945GSEJT, monitor connected via DVI).

A few things to test:
- How does that screen fare on a working machine? Would tell us if the
issue is with the sink or the source.
- Please boot up with drm.debug=0xe on a working and broken kernel, grab
dmesg for both.
- Extending the timeout magic might be worth a shot like in the below
patch. Crank up retry if it doesn't help.

This is strange, after connecting a different monitor (Fujitsu-Siemens
Scaleoview D19-1) as a second screen via DVI, both monitors came up fine
and even after removing it (and reverting everything to the status quo
ante), this HDMI connected Medion MD20094 monitor continues to work on
the previously broken sandy-bridge DH67CL mainboard.
Despite this problem being 100% reproducable and bisectable before,
including multiple power cycles and replacing the HDMI cable, I have not
been able to reproduce the issue again.

It is working fine on a Baytrail-D (ASRock Q1900DC-ITX) and an ivy-bridge
(Gigabyte GA-H77M-D3H r1.1) system - and now on the previously affected
sandy-bridge system (Intel DH67CL) as well.

dmesg-v4.4-rc4-113-g0bd0f1e-working.gz is attached, unfortunately I'm no
longer able to reproduce the previous failure (tested with easy of the
bisection steps, identical kernel binaries as before, and v4.4-rc5 as
well), so I can't provide a broken trace.

I can only imagine that it was right beyond the brink of the timeout
before and something had a lasting, but probably subtile, effect on the
timing after temporarily connecting the second screen; it is working now.

Thanks a lot and sorry for your trouble, I'll report back if anything
changes - or if I can reproduce the problem again.

Ah no worries, this happens fairly often ;-) Could be the cable had a bad
day or something like that. Also someone from intel noticed that the delay
isn't quite working like it should (we don't do the full 3x10ms delay),
patch for that should go to upstream hopefuly soon.
Anyway, thanks for reporting.
Cheers, Daniel
