RFC patch on top of 34d59508 (drm/nouveau: fix TTM_PL_TT memtype on pre-nv50)

Commit 0a0afd28 (drm/nv50-/disp: move DP link training to core and
train from supervisor) removed a call to 'nouveau_dp_dpms' at the
bottom of nv50_display.c.

Without this call, 'xset dpms force {on,off}' does not have any effect
on my DP-attached monitor.

The attached proof-of-concept patch re-adds the call, as well as a partial
version of nouveau_dp_dpms which causes 'force off' to work again.

It is not clear to me how to trigger link training in the supervisor,
so nouveau_dp_dpms skips that step when handling DRM_MODE_DPMS_ON.
The result is that 'force on' does not cause the monitor to wake up,
and the connection is effectively dead.

Could somebody familiar with the driver could comment on the next
steps to undertake to restore the full {on,off} functionality?

[WIP,BROKEN] drm/nv50: Hack FORCE_DP_TRAIN method for DPMS  power-on

Hi Ben,

Excellent!  (FYI: I, for one, don't need any backports.)

In the meantime, I tried to kludge my way into getting the monitor to
wake up with another horrible hack (attached), but did not succeed
before running out of time.  Any idea?

I understand that both patches suffer from the race condition you were
trying to avoid in the first place, but an always on/off monitor is a
bit of a handicap :)

Alternatively/in addition, I would welcome hints on how to make Nouveau
survive power-cycling the monitor (e.g. by running a command over SSH to
reset the display).  The current behaviour is:

             [On, displaying]
                    =E2=86=93           Turn off
                  [Off]
                    =E2=86=93           Turn on
                [Booting]
                    =E2=8B=AE
      [OSD: No input; shutting down]
                    =E2=8B=AE
                [Standby]

Of course, feel free to suggest proper fixes, docs to read, and/or
patches to test.

Cheers, -D

A little feedback from my side.

I tried this yesterday with the 3.15.0-rc6 Kernel, but this misbehaviour
regarding the none working power management is still the same with my 
NVIDIA Corporation GT200GL [Quadro FX 4800] (rev a1) with NV50 Chipset(NVA0).

So it would be great to get this functionality asap ;-)

Forget to mention,

my monitor is connected via DVI and I have the same problem.
Is the rework you mentioned also valid for the DVI output, so is it worth fo me
to giv it a trial?

Nevertheless thanks for your work and best regards, Andy.

Hi Ilia, Ben,

I gave a shot at drm-next as of the following commit:

I have been running that kernel for a large part of a work day, and, so
far, it has worked pretty well.

Many thanks!

Below are a couple remaining issues, none of which are blocking in my
case (GeForce 9400/DP/Dell U2711), but which may be worth investigating
if they also happen with other hardware combinations:

 1. The display does not wake up from (timed-out or forced) sleep on
    keypress or mouse move as it used to.  Activating the OSD menu wakes
    up the panel; Nouveau seems to pick that up as a hint to get going;

 2. The panel's backlight flickers very noticeably after a soft power
    cycle.  It also flickers, but less noticeably, after a hard unplug/
    re-plug.  Force-switching to an unconnected input source and back
    makes it stable again.

Let me know if there's any way I can assist you further.  In the
meantime, thanks again=E2=80=94it seems I'm not stuck with 3.8 anymore!

Cheers, -D

dmesg from garbled display

The interesting thing here is that I waited for the dpms timeout, and the
screen flashed and came back on more or less immediately, but clean.  It's as
if something decided that the DPMS-off transition was "activity" and turned the
screen back on, properly this time.  I don't think that's a driver issue
though.

Not sure if/why it's causing a garbled display, but I did spot one bug from the
log that's causing link retraining when it's not needed:

I hope this is just the monitor being really confused as a result of whatever
went wrong before it.  If it's not, your monitor is doing the wrong thing and
it's going to cause it to immediately resume from a power off (we can work
around the problem if it's necessary).  But, in your log, your monitor is
saying "help! i lost the link! retrain me!" in response to DP_SET_POWER_D3,
which it is *explicitly* (according to the DP spec, and, well, common sense)
not supposed to do.

The monitor off/on thing is weird.  When I was trying to get 3.14 to work
(before discovering this bug report), I tried the nvidia binary driver and got
the same flash off/on thing.  However, dpms-off was working in 3.6.3, which I
unfortunately don't have lying around any more.  It seems strange that the

something to work around the monitor's response.  (Also, the monitor-off
screensaver works when I am in OS/X.)

I can get a log to verify if you like, later today.  If there's anything I can
get from 3.6 to see if it's doing something different, let me know;  I'm sure I
can find and build a 3.6 sometime in the next day or two if necessary.

If it's the same situation as Nouveau, then the binary driver probably ignored
the HPD_IRQ pulse from the monitor.  We need to care about it now (well, we
were *supposed* to already, but anyway) for MST support particularly.  I'm
pretty sure I can work around the issue in the driver if we need to, so that's

Don't know if this will help any, but 3.6.3 was the last kernel in which I was
able to a) run nouveau successfully and b) have the full monitor-off timeout
stuff work.

I don't pretend that I tried every in-between version, but in general between
3.7 and 3.11 I was never able to find the right magic words to get any kind of
operational display, or perhaps things were broken.  3.11 onwards works but
then we have the DP DPMS issue which is the original point of this bug report.

7fac4933 (matching your patch above).

The remaining issues mentioned in comment #8 appear to be fixed in my
configuration, too.  Thanks!  I think this ticket can be closed.
