[vega] No outputs definitely connected, trying again...

[tourette]

Hello.
At last I succeeded on installing amdgpu. Kernel [Michael's one with DC code] seems to load module almost fine.
There is only one strange message in the log:

[drm] Cannot find any crtc or sizes

But the driver seems to be loaded successfully:

[drm] Initialized amdgpu 3.20.0 20150101 for 0000:03:00.0 on minor 1

However, there is black screen after loading: somewhy, X does not see my display:

[ 26.131] (II) AMDGPU(0): Output DisplayPort-0 disconnected
[ 26.131] (II) AMDGPU(0): Output DisplayPort-1 disconnected
[ 26.131] (II) AMDGPU(0): Output DisplayPort-2 disconnected
[ 26.131] (II) AMDGPU(0): Output HDMI-A-1 disconnected
[ 26.131] (WW) AMDGPU(0): Unable to find connected outputs - setting 1024x768 initial framebuffer

(In fact, monitor is connected to HDMI-A-1).

My system is ubuntu 17.04 with packages from Padoka ppa and Michael's kernel.
The amdgpu.dc=1 is set.


Any Ideas what I missed?

I had some issues with HDMI, would help maybe to see your full X log. Make sure your firmware is installed correctly.

Did that, still got black screen.
New X log: https://pastebin.com/WWbHqYGK

Btw, why you think amdgpu should not work with integrated driver enabled?

Also, monitor connected to the graphic card through dvi->HDMI-A-1 cable.
Maybe that matters?

what do you mean by dvi->HMDI-A-1 cable? Does the monitor light up when connected directly rather than using some sort of adapter?

I mean cable like this one: https://items.s2.citilink.ru/51606_v01_b.jpg

Not sure if I understood the question correctly. How can I plug the monitor "directly"? I need a cable anyway.
I cannot use hdmi-hdmi cable, because the monitor has only vga and dvi sockets.

With my cable it works well on windows and linux in VESA mode (with nomodeset enabled).
When i trying to use amdgpu, the screen is black (however, there is no "no signal" message).

Kernel 4.12.13+ from m-bab

[tourette]

Interesting.

AOC 28" 4K monitor

Well, I got Envision P2273wL, but I doubt that it matters.

Could you give the exact link? I don't know what m-bab is...

It's some guys who compile kernels for the community.
I run an older kernel just cause it works decent and was the first functional for me.

https://github.com/M-Bab/linux-kernel-amdgpu-binaries

[tourette]

Tried that kernel... same negative result.
(there is no 4.12.13+ version, so i tried 4.13.6+).


Also, I just found that I forgot to say one thing: my graphic card is not Vega Frontier Edition.
It is Sapphire vega. So maybe I need different firmware?

Also, another strange message in X log:

[ 20.797] (--) AMDGPU(0): Chipset: "Unknown AMD Radeon GPU" (ChipID = 0x687f)

And another question:
How can I build the dc kernel myself? (I can try to debug the driver ).

As far as I understand,

• I need a stock 4/15 kernel from kernel.org (which right now is called 4.14-rc5),
• Also I need ubuntu kernel patches (where can I get them)
• and some amd patches

Am I right?
