From 3ee2b9db5a5c9977c6bd726d0e5d12f5ac07d5cf Mon Sep 17 00:00:00 2001 From: Tianjie Xu Date: Mon, 27 Mar 2017 14:12:26 -0700 Subject: Log temperature during OTA update Log the maximum temperature as well as the start/end temperature of an update to last_install. Check the temperature at the end of each block_image_update(verify). To get the maximum temp, we iterate through /sys/class/thermal/thermal_zone*/temp and find the maximum value present. Bug: 32518487 Test: temperature logs in last_install Change-Id: Iaf22a9fbc5b18611bbc5320ffea995417872e514 --- otautil/ThermalUtil.h | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 otautil/ThermalUtil.h (limited to 'otautil/ThermalUtil.h') diff --git a/otautil/ThermalUtil.h b/otautil/ThermalUtil.h new file mode 100644 index 000000000..43ab55940 --- /dev/null +++ b/otautil/ThermalUtil.h @@ -0,0 +1,24 @@ +/* + * Copyright (C) 2017 The Android Open Source Project + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ + +#ifndef OTAUTIL_THERMALUTIL_H +#define OTAUTIL_THERMALUTIL_H + +// We can find the temperature reported by all sensors in /sys/class/thermal/thermal_zone*/temp. +// Their values are in millidegree Celsius; and we will log the maximum one. +int GetMaxValueFromThermalZone(); + +#endif // OTAUTIL_THERMALUTIL_H -- cgit v1.2.3
