vramEnergyCounter and totalCardEnergyCounter are broken on Arc B580 and always return 0 #138
Description
vramEnergyCounter and totalCardEnergyCounter are broken on Arc B580 and always return 0. Only gpuEnergyCounter works but this gives only GPU chip power draw.
Code sample I use:
ctl_power_telemetry_t power_telemetry = { 0 };
power_telemetry.Size = sizeof(ctl_power_telemetry_t);
double current_power_limit_milliwatts = 0.0;
ctl_pci_properties_t pci_properties = { 0 };
pci_properties.Size = sizeof(ctl_pci_properties_t);
ctl_pci_state_t pci_state = { 0 };
pci_state.Size = sizeof(ctl_pci_state_t);
ctlPowerTelemetryGet(igcl_devices[i], &power_telemetry);
ctlOverclockPowerLimitGet(igcl_devices[i], ¤t_power_limit_milliwatts);
ctlPciGetProperties(igcl_devices[i], &pci_properties);
ctlPciGetState(igcl_devices[i], &pci_state);
gpus[i].temperature = to_uint(power_telemetry.gpuCurrentTemperature.value.datadouble);
gpus[i].fan = to_uint(power_telemetry.fanSpeed[0].value.datadouble);
gpus[i].clock_core = to_uint(power_telemetry.gpuCurrentClockFrequency.value.datadouble);
gpus[i].clock_memory = to_uint(power_telemetry.vramCurrentClockFrequency.value.datadouble);
gpus[i].clock_memory_max = max(gpus[i].clock_memory_max, gpus[i].clock_memory);
const double igcl_current_energy = fmax(power_telemetry.gpuEnergyCounter.value.datadouble+power_telemetry.vramEnergyCounter.value.datadouble, power_telemetry.totalCardEnergyCounter.value.datadouble);
const double igcl_current_energy_timestamp = power_telemetry.timeStamp.value.datadouble;
gpus[i].power_used = to_uint((igcl_current_energy-igcl_last_energy[i])/(igcl_current_energy_timestamp-igcl_last_energy_timestamp[i]));
gpus[i].power_max = to_uint(current_power_limit_milliwatts*0.001);
gpus[i].power = 100u*gpus[i].power_used/max(gpus[i].power_max, 1u);
gpus[i].pcie_bandwidth_max = (uint)(pci_properties.maxSpeed.maxBandwidth/1000000ull);
gpus[i].pcie_bandwidth_used = (uint)(pci_state.speed.maxBandwidth/1000000ull);
gpus[i].pcie_bandwidth_usage = to_uint(100.0f*(float)pci_state.speed.maxBandwidth/(float)pci_properties.maxSpeed.maxBandwidth);
igcl_last_energy[i] = igcl_current_energy;
igcl_last_energy_timestamp[i] = igcl_current_energy_timestamp;
