Methods inherited from telemetry.internal.platform.linux_based_platform_backend.LinuxBasedPlatformBackend:
- GetClockTicks(*args, **kwargs)
- Returns the number of clock ticks per second.
The proper way is to call os.sysconf('SC_CLK_TCK') but that is not easy to
do on Android/CrOS. In practice, nearly all Linux machines have a USER_HZ
of 100, so just return that.
- GetCpuStats(self, pid)
- GetCpuTimestamp(self)
- GetMemoryStats(self, pid)
- GetSystemCommitCharge(self)
- # Get the commit charge in kB.
- GetSystemTotalPhysicalMemory(*args, **kwargs)
Methods inherited from telemetry.internal.platform.platform_backend.PlatformBackend:
- CanCaptureVideo(self)
- CanLaunchApplication(self, application)
- CanMeasurePerApplicationPower(self)
- CanMonitorNetworkData(self)
- CanMonitorThermalThrottling(self)
- CanTakeScreenshot(self)
- CooperativelyShutdown(self, proc, app_name)
- Cooperatively shut down the given process from subprocess.Popen.
Currently this is only implemented on Windows. See
crbug.com/424024 for background on why it was added.
Args:
proc: a process object returned from subprocess.Popen.
app_name: on Windows, is the prefix of the application's window
class name that should be searched for. This helps ensure
that only the application's windows are closed.
Returns True if it is believed the attempt succeeded.
- DidCreateBrowser(self, browser, browser_backend)
- DidStartBrowser(self, browser, browser_backend)
- FlushDnsCache(self)
- GetArchName(self)
- GetDeviceTypeName(self)
- GetNetworkData(self, browser)
- InitPlatformBackend(self)
- InstallApplication(self, application)
- IsApplicationRunning(self, application)
- IsCooperativeShutdownSupported(self)
- Indicates whether CooperativelyShutdown, below, is supported.
It is not necessary to implement it on all platforms.
- IsDisplayTracingSupported(self)
- LaunchApplication(self, application, parameters=None, elevate_privilege=False)
- PurgeUnpinnedMemory(self)
- ReadMsr(self, msr_number, start=0, length=64)
- Read a CPU model-specific register (MSR).
Which MSRs are available depends on the CPU model.
On systems with multiple CPUs, this function may run on any CPU.
Args:
msr_number: The number of the register to read.
start: The least significant bit to read, zero-indexed.
(Said another way, the number of bits to right-shift the MSR value.)
length: The number of bits to read. MSRs are 64 bits, even on 32-bit CPUs.
- SetFullPerformanceModeEnabled(self, enabled)
- SetPlatform(self, platform)
- StartDisplayTracing(self)
- Start gathering a trace with frame timestamps close to physical
display.
- StartVideoCapture(self, min_bitrate_mbps)
- StopDisplayTracing(self)
- Stop gathering a trace with frame timestamps close to physical display.
Returns a raw tracing events that contains the timestamps of physical
display.
- StopVideoCapture(self)
- TakeScreenshot(self, file_path)
- WillCloseBrowser(self, browser, browser_backend)
