Ok that makes sense. I didn't think about generic modesetting driver for Xserver.
And that indeed works. This is my xorg.conf:
----------------------->8----------------------
# cat /etc/X11/xorg.conf 
Section "Device"
        Identifier      "Driver0"
        Screen          0
        Driver          "modesetting"
        Option          "kmsdev" "/dev/dri/card1"
EndSection
----------------------->8----------------------

I do see xclock is rendered fine.

Now I guess is getting closer to what I really need :)
In the end I wanted to get 3D rendered by Vivante GPU
to be displayed on UDL. My assumption was very simple - if IMX-DRM+Etnaviv
work fine it should be straight-forward to swap IMX-DRM bitstreamer with UDL
and we're golden.

That might be more a question to Lucas now.
I use xorg.conf as found here:
http://git.arm.linux.org.uk/cgit/xf86-video-armada.git/tree/conf/xorg-sample.conf?h=unstable-devel
That's what it has:
----------------------->8----------------------
Section "Device"
	Identifier	"Driver0"
	Screen		0
	Driver		"armada"

# Support hotplugging displays?
#	Option		"Hotplug"	"TRUE"

# Support hardware cursor if available?
#	Option		"HWCursor"	"TRUE"

# Use GPU acceleration?
#	Option		"UseGPU"	"TRUE"

# Provide Xv interfaces?
#	Option		"XvAccel"	"TRUE"

#	Option		"XvPreferOverlay" "TRUE"

#	Option		"AccelModule"	"etnadrm_gpu"
#	Option		"AccelModule"	"etnaviv_gpu"

# Support DRI2 interfaces?
#	Option		"DRI"		"TRUE"
EndSection
----------------------->8----------------------

Indeed I uncommented all the lines and then it allows to see
for example glmark2-es2 working on Wandboard (that's exactly where
"imx-drm + etnaviv" combo is used).

But if I swap "imx-drm" to "udl" I don't see anything on my screen
(connected via UDL) even though Xserver seems to really start claiming the screen
(so I see it becomes black, effectively overriding whatever was there before) and
glmark benchmark prints results.

Maybe I'm missing some additional glue for UDL in "xf86-video-armada" except the simple one:

Which drm driver uses /dev/dri/card0? I'm seing drmOpen code and
if you don't specify the busID it will fallback for the first
card that matches "armada-drm" or "imx-drm" or "udl".

Xorg.log can help confirm if everything is ok.

I'm wondering if this means that target format for UDL is YUV ...

But anyway, I revisited your first email and noticed that you
said kmscube runs fine. Is this using etnaviv as renderer? And
you also said X is claiming the screen but nothing appears ...
which X client are you using to test this?

Indeed, in case of kmscube etnaviv is a renderer while UDL
outputs the picture on the screen.

Well it might be seen from my full log.
I just start X with "X&" command and then
execute things like "xclock".

So not sure who is a client in that case.

As you've noticed, drmOpen can give you some 'nice' side-effects.
I'd recommend getting a list of devices with drmGetDevice{,s}2 and
applying $heuristics to filter the device you want.

Thats nice :)

Ok, from your logs I was not able to see anything wrong. X server
does not error exit and Prime seems to be working in DRM ...

Lets try one more thing: Enable all debug in DRM (drm.debug=0x3f)
and try to correlate the log with the actions. i.e.

[boot]
[log]
[x start]
[log]
[xclock start]
[log]
[glmark2-es2 start]
[log]

If that does not give any more info then maybe someone with
better understanding of etnaviv, UDL and X can help (maybe cc X
devel list also ...)

Best Regards,
Jose Miguel Abreu

I think I have something like that.

Below are extracts which show at least one difference I was able to find.
And that difference is presence of "[drm:udl_drm_gem_mmap] flags = 0x1"
in case of Xserver only.

From my note above about udl_drm_gem_mmap() being only used in case of Xserver
I barely may conclude anything. Given my lack of knowledge of DRM guts
especially
when it comes to complicated cases with DMA buffer exports/imports I cannot say
immediately if that's just improper implementation of
udl_drm_gem_mmap() or not.
Even though I do see some differences between implementation of file_operations->mmap()
callback in UDL and
say exynos_drm_gem_mmap() or qxl_mmap() it's not clear
why this and that implementation was done.

Well at this point I think its purely a UDL driver problem because if we swap UDL to
imx-drm on Wandboard everything works perfectly fine!

Oh, I've seen this before. This is the same thing that arcpgu
used to do in the mmap callback! Please comment out the call to
update_vm_cache_attr() in the mmap callback and check if it works.

Actually I did it as the first thing when I spotted it in udl_drm_gem_mmap().
But that made no difference at all :(
