Nouveau on a Jetson TK1 problems

Nouveau on a Jetson TK1 problems

[ben]

I hope this is a good mailing list for this problem. I have a Jetson TK1 
board and I am trying to get the nouveau drivers running on it without 
success. I am using the following:

Nouveau linux kernel 4.8.0-rc4+
Nouveau DRM git master
xf86-video-nouveau git master
Gnurou xserver  git branch GK20A

My base system is Debian.

When I try to start X I get:  X: drmmode_display.c:783: 
drmmode_crtc_init: Assertion `ret == 0' failed. There is also a kernel 
log message: [drm] Cannot find any crtc or sizes - going 1024x768

lsmod shows:

Re: Nouveau on a Jetson TK1 problems

[C Bergström]

Is there any particular reason you're not using the open source NVIDIA
Tegra drivers?

This is what is being used for the TX1 (Sorry I don't know if it's the
same for the TK1)

That's ... not particularly helpful. Presumably non-upstream and the
fact that it's ancient are turn-offs. Either way, he seems to have a
desire to try to get nouveau going.

I don't think I've seen this before. The odd thing about the TK1 (and
TX1, I believe), is that the GK20A device doesn't have any display
capabilities - those are left up to tegra. Sounds like you're trying
to use the nouveau ddx as the primary, which fails as there are no
CRTC's. I believe Gnurou's xserver hacks rely on you using glamor (and
thus the modesetting xorg ddx). Is that what you're using? Can you
provide an xorg log?

Cheers,

Compared to buggy, not working and pointless?

"ancient" it's like saying everything that RH ships is worthless..

I was hoping not to get trolled and instead to get sincere feedback
from the user about what his needs might be. It may be simple
curiosity or actually something technical. So I'm happy you may be
able to help him on his mission, but attacks (esp stupid ones) aren't
appreciated.

mhh, I thought nouveau _is_ the new thing officially for tegra? Or did I
miss anything?

Well it works like that basically:
modesetting DDX runs on top of the tegra 2d engine and 2d acceleration
is provided by prime offloaded glamor on top of mesa on the 3d engine
driven by nouveau.
Which basically means: remove xf86-video-nouveau

Posting your /var/log/Xorg.0.log would be most helpful at this point,
to understand which DDX is being used. On Tegra, you want to use the
modesetting DDX since the display device is driven by tegradrm and
thus not Nouveau-supported.

If you want any kind of acceleration, you will also need to patch X
for the same reason (see the two top commits at
https://github.com/Gnurou/xserver/commits/gk20a). GLamor can be used
with modesetting for hw acceleration, but this requires plugging the
display and rendering devices using PRIME (which X does not support
out-of-the-box at the moment).

These X patches in turn require the following kernel patch which is
not upstreamed yet:
https://github.com/Gnurou/linux/commit/8b06bf92b8da6bee92c3a2a8eaccd74ed3dd1939

Having to patch around is a bit boring, but once you get things
working X on TK1 is a rather pleasant experience (with or without
acceleration). Please let me know if anything is unclear!

Cheers,
Alex.
