Python Device.get_device_id Examples

Example #1

def get_wbt_lat(device: Device):
    wbt_lat_config_path = os.path.join(get_sysfs_path(device.get_device_id()),
                                       "queue/wbt_lat_usec")

    return int(
        TestRun.executor.run_expect_success(
            f"cat {wbt_lat_config_path}").stdout)

Example #2

def set_wbt_lat(device: Device, value: int):
    if value < 0:
        raise ValueError("Write back latency can't be negative number")

    wbt_lat_config_path = os.path.join(get_sysfs_path(device.get_device_id()),
                                       "queue/wbt_lat_usec")

    return TestRun.executor.run_expect_success(
        f"echo {value} > {wbt_lat_config_path}")
