amdgpu_top fails to start at times

[sobornostea]

Hello,

I sometimes encounter a problem where running amdgpu_top is not possible. When it happens I also can't read the temperature from KDE System Monitor and the performance seems to degrade

Here is the error message I get :

amdgpu_device_initialize: DRM version is 0.0.0 but this driver is only compatible with 3.x.x.
Failed to DeviceHandle::init

        ),
    },

Please attach the results of ls /sys/bus/pci/devices/0000:04:00.0 and cat /sys/bus/pci/devices/0000:04:00.0/pp_dpm_sclk, cat /sys/bus/pci/devices/0000:04:00.0/pp_dpm_mclk .

Thanks.
I don't know why the parsing fails, but this commit should have fixed it.
Umio-Yasuno/libdrm-amdgpu-sys-rs@aa66f78

It might be related to the APU+dGPU system environment.
