Could you add the expected units of voltage/current in 2.4 metrics structure? Is it mV/mA or mV/A?
Thanks,
Lijo

Subject: [PATCH] drm/amd/pm: Vangogh: Add new gpu_metrics_v2_4 to acquire gpu_metrics
To acquire the voltage and current info from gpu_metrics interface, but gpu_metrics_v2_3 doesn't contain them, and to be backward compatible, add new gpu_metrics_v2_4 structure.
