Android各种部件温度获取逻辑探究

Preface

事件的来源是做一个性能监测工具获取GPU，电池温度数据时反了snapdragon的pluginGPU-GGPM的so，这个so对应会获取GPU General的GPU theramal也就是GP温度数据。snapdragon会把获取温度的文件名通过logcat打出来，如下:

sub_94FE0(v69, 1LL, "GGPMProvider", "GGPM_DP: Reading GPU Temperature from '/sys/class/kgsl/kgsl-3d0/temp'");

可以在snapdrgon连接上手机后从logcat日志出看出这一句:

grus:/ $ logcat | grep Temperature
11-23 11:01:53.264 17088 17088 I SDP     : SDPCore.Metric: Metric 'GPU Temperature' activated for all processes
11-23 11:10:12.597 23936 23936 I SDP     : GGPMProvider: GGPM_DP: Reading GPU Temperature from '/sys/devices/virtual/thermal/thermal_zone29/temp'

也就是说snapdrgon是从/sys/devices/virtual/thermal/thermal_zone29/temp这个文件中拿出的GPU温度数据。

在这之前，我获取CPU温度数据的逻辑也是从一些文件中读取数据，比如:


            "/sys/class/thermal/thermal_zone7/temp",
            "/sys/devices/virtual/thermal/thermal_zone7/temp",
//            "/sys/kernel/debug/tegra_thermal/temp_tj",
//            "/sys/devices/platform/s5p-tmu/curr_temp",
//            "/sys/devices/virtual/thermal/thermal_zone1/temp",//常用
//            "/sys/devices/system/cpu/cpufreq/cput_attributes/cur_temp",
//            "/sys/devices/virtual/hwmon/hwmon2/temp1_input",
//            "/sys/devices/platform/coretemp.0/temp2_input",
//            "/sys/devices/virtual/thermal/thermal_zone0/temp",
//            "/sys/devices/system/cpu/cpu0/cpufreq/cpu_temp",
//            "/sys/devices/platform/omap/omap_temp_sensor.0/temperature",
//            "/sys/class/thermal/thermal_zone1/temp",
//            "/sys/devices/platform/s5p-tmu/temperature",
//            "/sys/devices/w1 bus master/w1_master_attempts",
//            "/sys/class/thermal/thermal_zone0/temp"

​

 
            "/sys/devices/virtual/thermal/thermal_zone0/temp",
            "/sys/class/thermal/thermal_zone0/temp",
            "/sys/kernel/debug/tegra_thermal/temp_tj",
            "/sys/devices/platform/s5p-tmu/curr_temp",
            "/sys/devices/virtual/thermal/thermal_zone1/temp",
            "/sys/devices/system/cpu/cpufreq/cput_attributes/cur_temp",
            "/sys/devices/virtual/hwmon/hwmon2/temp1_input",
            "/sys/devices/platform/coretemp.0/temp2_input",
            "/sys/devices/platform/omap/omap_temp_sensor.0/temperature",
            "/sys/class/thermal/thermal_zone1/temp",
            "/sys/devices/platform/s5p-tmu/temperature",
            "/sys/devices/w1 bus master/w1_master_attempts",
            "/sys/devices/system/cpu/cpu0/cpufreq/cpu_temp",
            "/sys/devices/system/cpu/cpu0/cpufreq/FakeShmoo_cpu_temp",
            "/sys/class/i2c-adapter/i2c-4/4-004c/temperature",
            "/sys/devices/platform/tegra-i2c.3/i2c-4/4-004c/temperature",
            "/sys/devices/platform/tegra_tmon/temp1_input",
            "/sys/class/hwmon/hwmon0/device/temp1_input",
            "/sys/devices/virtual/thermal/thermal_zone1/temp",
            "/sys/class/thermal/thermal_zone3/temp",
            "/sys/class/thermal/thermal_zone4/temp",
            "/sys/class/hwmon/hwmonX/temp1_input",
            "/sys/devices/platform/s5p-tmu/curr_temp"

可以看到，获取CPU温度中主要使用了/sys/devices/virtual/thermal/thermal_zone7/temp。现在的问题是，这些thermal_zone到底有什么作用? 如何使用分辨不同的thermal_zone的作用?

Manuscript

为了解决上述的问题，有了下面的探究。

不同的厂家和设备之间可能存在着明显的兼容性问题，因此此处表明本次测试环境是XIAO MI9 SE, MIUI 12.0.3, Android 10。

深究thermal_zone

比如gpu-virt-max-step的thermal_zone，这个概念其实在安卓内核源码中: qti_virtual_sensor.c:

​
static const struct virtual_sensor_data qti_virtual_sensors[] = {
    {
        .virt_zone_name = "gpu-virt-max-step",
        .num_sensors = 2,
        .sensor_names = {"gpu0-usr",
                "gpu1-usr"},
        .logic = VIRT_MAXIMUM,
    },
    ....
};

在这个结构中，virt_zone_name也就是thermal_zone的type，而sensor_names决定了数据的来源，在这里也就是数据来源是名为gpu0-usr和gpu1-usr的两个温度传感器。

具体有多少个传感器，分别有什么作用，取决于SOC厂商，不过SOC厂商会将这些信息写入到安卓源码中。

高通SOC传感器

在安卓源码中，platform/hardware/qcom/ 下面列出了高通一些soc的硬件信息。

比如thermal_target.c就列出了在android13下sdm845处理器的一些传感器信息。

  • qcom android9: android.googlesource.com/platform/ha…
  • qcom android10: android.googlesource.com/platform/ha…
  • qcom android11: android.googlesource.com/platform/ha…
  • qcom android12: android.googlesource.com/platform/ha…

// TODO: pm660l_tz 和 battery的逻辑不是很清楚, 不过pm代表的是power management, 也就是Power Control IC。

联发科SOC传感器

在android源码中，关于早期联发科的一些温度传感器和monitor的信息在: mtk_thermal_monitor.c文件中。

static int mtk_thermal_get_tz_idx(char *type)
{
    if (0 == strncmp(type, "mtktscpu", 8))  // CPU thermal
        return MTK_THERMAL_SENSOR_CPU;
    else if (0 == strncmp(type, "mtktsabb", 8))
        return MTK_THERMAL_SENSOR_ABB;
    else if (0 == strncmp(type, "mtktspmic", 9))
        return MTK_THERMAL_SENSOR_PMIC;
    else if (0 == strncmp(type, "mtktsbattery2", 13))
        return MTK_THERMAL_SENSOR_BATTERY2;
    else if (0 == strncmp(type, "mtktsbattery", 12))
        return MTK_THERMAL_SENSOR_BATTERY;  // battery
    else if (0 == strncmp(type, "mtktspa", 7))
        return MTK_THERMAL_SENSOR_MD1;
    else if (0 == strncmp(type, "mtktstdpa", 9))

}

海思麒麟SOC

只有远古时期的一份配置文件大概写了部分的传感器作用: android.googlesource.com/device/huaw…

...
[SS-CPU1]
#algo_type ss
sampling 10
sensor cpu1
device cluster0
set_point 85000
set_point_clr 55000
time_constant 0
    
[SS-CPU0]
#algo_type ss
sampling 10
sensor cpu0
device cluster0
set_point 85000
set_point_clr 55000
time_constant 0
...

例如cluster0被用于代表CPU的温度，gpu代表GPU的温度，Battery用于电池温度。

总结

获取GPU, CPU以及battery等温度数据可以通过读取对应thermal_zone文件下的temp文件来获得，但是需要注意，由于不同手机厂商的方案不同，这些文件的type以及文件权限并不一定相同。目前看到的情况如下:

小米手机:

可以正常读取 /sys/class/thermal/ 路径下的文件夹和文件。
​
例如小米9 SE:
grus:/ $ cat /sys/class/thermal/thermal_zone44/type
battery
​
grus:/ $ cat /sys/class/thermal/thermal_zone29/type
gpu-virt-max-step
​

华为手机:

/sys/class/thermal/ 路径下的文件夹和文件权限不够;
可以通过读取 /sys/devices/virtual/thermal/ 路径下的文件夹和文件获取数据。
​
例如华为p30:
HWELE:/ $ cat /sys/devices/virtual/thermal/thermal_zone3/type
Battery
​
HWELE:/ $ cat /sys/devices/virtual/thermal/thermal_zone9/type
gpu
​

IQOO手机:

可以正常读取 /sys/class/thermal/ 路径下的文件夹和文件。
​
例如IQOO Z3:
PD2073:/ $ cat /sys/class/thermal/thermal_zone90/type
battery
​
PD2073:/ $ cat /sys/class/thermal/thermal_zone45/type
gpuss-max-step
​

OPPO手机:

可以正常读取 /sys/class/thermal/ 路径下的文件夹和文件。
​
例如OPPO Reno:
OP46B1:/ $ cat /sys/class/thermal/thermal_zone44/type
battery
​
OP46B1:/ $ cat /sys/class/thermal/thermal_zone33/type
gpu-virt-max-step
​

当然，也可以通过dumpsys来拿取温度信息例如:

fuxi:/ $ dumpsys battery
Current Battery Service state:
  AC powered: false
  USB powered: true
  Wireless powered: false
  Dock powered: false
  Max charging current: 500000
  Max charging voltage: 5000000
  Charge counter: 3918

  health: 2
  present: true

  scale: 100
