Just booted drm-next on a Skylake laptop that happened to be on my
desk for a few days.
I wasn't impressed. I'm very disappointed. Doesn't anyone have any
pride in the code they write anymore.
Initially the previous sentence had a lot of curse words and was Linus
like in it's stature, but I've been promised by twitter that being
nice will get me better results, so let's make it so.
So could someone from Intel takes some responsibility for testing the
code they send me actually you know works on the hardware it's meant
to, or at least tell me what is going so horribly wrong here.
the lockdep trace at the end doesn't look fun.
Dave.

Skylake wants the DMC firmware blob from linux-firmware or
https://01.org/linuxgraphics/downloads. The conclusion from the traces
below is that either you don't have it, or we fail to load it due to the
deadlock.
In any case, our DMC firmware loading is, uh, less than perfect.
The bright side is that we are aware of this, and there's a couple of
patchsets from Mika/Damien [1] and Animesh/Daniel/Imre [2] to fix
this. (Mika, Imre, any comments on the status of those?)
The bigger question is how do we fix this for drm-next/v4.4. That's 20
patches in total, and we are way past the cutoff. On the other hand,
it's all restricted to Skylake DMC firmware loading, and it is supposed
to fix stuff, not add features.
Your call.
BR,
Jani.

That's from the GuC firmware loader, so won't be fixed by the DMC
patches. Ville mentioned he has a fix for that.

All of Mika's patches [1] have an R-b, except patch 7/7.
[2] has R-b's as well except for patch 1/13. Sunil any update on that?

Yes, no new features, only fixes.

No, I don't. I probably just mentioned that I saw this lockdep spew
already some weeks ago, and complained about it at the time. I think
Daniel tried to ping someone specific about it, but no idea if they
took any notice.

From my perspective outside Intel, since the QA took a dive, I think
the pipeline is far too long now.
We've added delays to the pipeline previously to facilitate QA, but
when QA is removed we haven't shortened the pipeline again.
I'm kind of tempted to ask you guys to throw away everything queued up
in drm-intel-next on the basis that it has probably had 0 actual
testing and start again.
We have a major process failure in place here, and shoving more code
in the backend and hoping it somehow magically fixes itself between
drm-intel-next and merging to Linus's tree is clearly not working for
the past 6 months at least. I'm really unhappy about how shoddy 4.2
is, and 4.3 is clearly not shaping up to have been a winner, 4.4 is
looking even less fun.
So maybe you guys can brainstrom a bit, also when Daniel gets back.
But at the moment I think until QA is fully reestablished, I think not
merging anything to drm-intel-next for a few weeks and taking a break
on new features until some of the features that were merged broken
actually get fixed.
I'm also going to start looking at reverting skylake firmware loading,
it's clearly never been tested with lockdep enabled by anyone who
cared, which to my mind says it should never have been merged in the
first place.
Dave.

It could be that Dave is hitting the warm boot DMC fw loading issue so
you probably need my series [1] as well.

I think this is the right way to go. We have several known failures in
even our basic tests, and when we created that list the intention was to
"drop everything" if one of them failed on any of the past few platforms
(BYT+ on Atom and HSW+ on Core). So far we haven't done that but imo we
should.

It's necessary but not sufficient; see
http://lists.freedesktop.org/archives/intel-gfx/2015-November/079368.html
for fixing GuC itself.
I tested this on top of the three series (Mika's, Imre's, and yours),
but hit some power domain warnings and I never come back from DPMS.
That being said, this is also on top of Maarten's async atomic
pageflip series, so there could be some damage there. I'll try to
track that down separately and give you a more sensible Tested-by.
My other reservation with the DMC firmware series is that it requires
firmware v1.23, which is available from 01.org, but hasn't been
submitted to linux-firmware AFAICT. So that'll break DMC for everyone
who doesn't explicitly grab the firmware ...
Cheers,
Daniel

Hi Daniel
Yes, the GuC is a separate issue from the DMC ones. I'll have a look
at your patch.

It's possible that our changes collide. I'm not up-to-date with the
latest atomic work but can take a look as well tomorrow.
Thanks

Yeah, turns out I'd just subtly broken the power domain handling when
pulling your 'turn DC handling into power well' changes on top of
Maarten's async-atomic work. All seems well with that resolved.

Daniel
