- Method resolution order:
- SysfsPowerMonitor
- telemetry.internal.platform.power_monitor.PowerMonitor
- __builtin__.object
Methods defined here:
- CanMonitorPower(*args, **kwargs)
- GetCpuFreq(self)
- Retrieve CPU frequency times from the device.
Returns:
Dictionary containing frequency times for each CPU.
- GetCpuState(self)
- Retrieve CPU c-state residency times from the device.
Returns:
Dictionary containing c-state residency times for each CPU.
- StartMonitoringPower(self, _browser)
- StopMonitoringPower(self)
- __init__(self, linux_based_platform_backend, standalone=False)
- Constructor.
Args:
linux_based_platform_backend: A LinuxBasedPlatformBackend object.
standalone: If it is not wrapping another monitor, set to True.
Attributes:
_cpus: A list of the CPUs on the target device.
_end_time: The time the test stopped monitoring power.
_final_cstate: The c-state residency times after the test.
_final_freq: The CPU frequency times after the test.
_initial_cstate: The c-state residency times before the test.
_initial_freq: The CPU frequency times before the test.
_platform: A LinuxBasedPlatformBackend object associated with the
target platform.
_start_time: The time the test started monitoring power.
Static methods defined here:
- CombineResults(cpu_stats, power_stats)
- Add frequency and c-state residency data to the power data.
Args:
cpu_stats: Dictionary containing CPU statistics.
power_stats: Dictionary containing power statistics.
Returns:
Dictionary in the format returned by StopMonitoringPower.
- ComputeCpuStats(initial, final)
- Parse the CPU c-state and frequency values saved during monitoring.
Args:
initial: The parsed dictionary of initial statistics to be converted
into percentages.
final: The parsed dictionary of final statistics to be converted
into percentages.
Returns:
Dictionary containing percentages for each CPU as well as an average
across all CPUs.
- ParseFreqSample(sample)
- Parse a single frequency sample.
Args:
sample: The single sample of frequency data to be parsed.
Returns:
A dictionary associating a frequency with a time.
Methods inherited from telemetry.internal.platform.power_monitor.PowerMonitor:
- CanMeasurePerApplicationPower(self)
- Returns True if the power monitor can measure power for the target
application in isolation. False if power measurement is for full system
energy consumption.
Data descriptors inherited from telemetry.internal.platform.power_monitor.PowerMonitor:
- __dict__
- dictionary for instance variables (if defined)
- __weakref__
- list of weak references to the object (if defined)
