When running nvtop on kernel version 6.6.0-rc3 the power usage no longer shows up.

GPU: AMD Radeon RX 550 nvtop version: 3.0.2

If you are wondering why the clocks are so low: i'm running with a tuned AMD PowerPlay/PowerTune profile optimized for power efficiency.

nvtop gets AMD GPU power consumption with _amdgpu_query_sensor_info(gpu_info->amdgpu_device, AMDGPU_INFO_SENSOR_GPU_AVG_POWER, sizeof(out32), &out32). https://github.com/Syllo/nvtop/blob/master/src/extract_gpuinfo_amdgpu.c#L727-L732

The AMDGPU driver now uses AMDGPU_PP_SENSOR_GPU_AVG_POWER internally due to recent changes.
This causes some AMD GPUs that do not support AMDGPU_PP_SENSOR_GPU_AVG_POWER to return an error for AMDGPU_INFO_SENSOR_GPU_AVG_POWER. https://gitlab.freedesktop.org/agd5f/linux/-/commit/47f1724db4fe0085b33cafd68bb8b7267678bb95

I will report it to drm/amd .

@Umio-Yasuno Tested. Apologies for taking so long, forgot all about it.

Patches have been merged in 6.7.2, this issue is now resolved for me. Tested on a AMD Radeon Polaris RX 580.
