Power measurement on Metis

Hi ​@Aimar.gnz! 

I think axmonitor might be what you’re looking for. It's Voyager’s system monitoring tool that can show core temperature, utilisation, and on supported hardware, power metrics as well.

There's a tutorial in the SDK docs here: https://github.com/axelera-ai-hub/voyager-sdk/blob/HEAD/docs/tutorials/axmonitor.md

Let me know how you get on!

Hi ​@Spanner , 

The thing is power metrics are only available on 4-Metis PCIe cards, and I only have one, so I was wondering whether there was an alternative way.
I am using a smart plug that gives actual power metrics, but my AIPU is not recognised in the Metis compute board.

Error is:
 The Metis card is visible on PCIe, but during boot the driver reads an invalid firmware header:
      - Invalid hdrv magic 0
      - Fail to get hdrv area

Really stuck with this.

Hello ​@Aimar.gnz ,

Regarding the messages that you see (- Invalid hdrv magic 0 - Fail to get hdrv area):

These messages are not an issue and the driver and Metis card are working as expected. 

We are aware that these messages can be confusing to the user, as they do not mean there are any issues. Therefore, I have raised this internally and we will remove these traces in next releases.

To sum up, do not worry about those messages, everything is working well.

Best,

Victor
