Cannot launch on Radeon VII

[viggy96]

I get the following error when trying to launch the programme:

Reading clock states and limits.
Traceback (most recent call last):
  File "run.py", line 23, in <module>
    wattman.main()
  File "/home/vignesh/Downloads/WattmanGTK/WattmanGTK/wattman.py", line 151, in main

I have the same problem.
I'm running Ubuntu 18.04.1 with driver version 18.50.

Same here with rx580, ubuntu 18.04.1 amdgpu-pro 18.50

Same with Radeon VII on Xubuntu 18.04, 4.20.13 Kernel, and Padoka Unstable PPA

[2m]

Same here with 5.0.0 kernel. Can we help you somehow to implement this? Here is the contents of pp_od_clk_voltage of Radeon VII:

Same issue here! Sabayon Linux kernel 5.0.15

Same here.

Here's a quick and dirty patch that makes it work for radeon vii. It most likely breaks with other cards, I guess the format was changed.

Edit:
For future reference in case someone wants to write a proper patch, the contents of my pp_od_clk_voltage looks like this:

2:       1801Mhz       1113mV

edit: @kbeckmann, your patch work for me (app starts, but i didn't investigate much further)

It's also broken for me
