- __builtin__.object
Methods defined here:
- CanMonitorPower(*args, **kwargs)
- StartMonitoringPower(self, browser)
- StopMonitoringPower(self)
- __init__(self, platform_backend)
- Constructor.
Args:
platform_backend: A LinuxBasedPlatformBackend object.
Attributes:
_initial_power: The result of 'dump_power_status' before the test.
_start_time: The epoch time at which the test starts executing.
Static methods defined here:
- IsOnBatteryPower(status, board)
- Determines if the devices is being charged.
Args:
status: The parsed result of 'dump_power_status'
board: The name of the board running the test.
Returns:
True if the device is on battery power; False otherwise.
- ParsePower(initial_stats, final_stats, length_h)
- Parse output of 'dump_power_status'
Args:
initial_stats: The output of 'dump_power_status' before the test.
final_stats: The output of 'dump_power_status' after the test.
length_h: The length of the test in hours.
Returns:
Dictionary in the format returned by StopMonitoringPower().
- ParsePowerStatus(sample)
- Parses 'dump_power_status' command output.
Args:
sample: The output of 'dump_power_status'
Returns:
Dictionary containing all fields from 'dump_power_status'
- SplitSample(sample)
- Splits a power and time sample into the two separate values.
Args:
sample: The result of calling 'dump_power_status; date +%s' on the
device.
Returns:
A tuple of power sample and epoch time of the sample.
Methods inherited from telemetry.internal.platform.power_monitor.sysfs_power_monitor.SysfsPowerMonitor:
- 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.
Static methods inherited from telemetry.internal.platform.power_monitor.sysfs_power_monitor.SysfsPowerMonitor:
- 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)
