三、power supply子系统简介 1. psy子系统中power_supply_class对应着系统中供电设备类，是一个抽象化的集合，对应着/sys/class/power_supply/目录，供电设备都在该目录之下，比如battery设备就对应该目录下一个子目录 struct power_supply表示一个psy供电设备，比如电池、AC、USB，一般可通过devm_power_supply_register函数注册成一个psy设备，在注册设备之前需要定义好该设备的 __power_supply_register负责注册一个psy设备： ? 在sysfs中有个power_supply_uevent，该函数在psy class初始化时注册为设备节点的dev_uevent，在每一个psy目录下都有一个uevent节点，读取该节点即调用power_supply_uevent

psy子系统中power_supply_class对应着系统中供电设备类，是一个抽象化的集合，对应着/sys/class/power_supply/目录，供电设备都在该目录之下，比如battery设备就对应该目录下一个子目录 相关结构体 psy相关的定义在/include/linux/power_supply.h。 struct power_supply表示一个psy供电设备，比如电池、AC、USB，一般可通过devm_power_supply_register函数注册成一个psy设备，在注册设备之前需要定义好该设备的 __power_supply_register负责注册一个psy设备： 在sysfs中有个power_supply_uevent，该函数在psy class初始化时注册为设备节点的dev_uevent 调用流程 psy子系统主要调度的逻辑都在power_supply_changed_work中。
本文将从设计思路、软件架构、API说明以及怎么编写power supply driver四个角度，介绍power supply class。 3.2 核心数据结构 1）struct power_supply struct power_supply为power supply class的核心数据结构，用于抽象PSY设备。 /POWER_SUPPLY_TYPE_USB_DCP /POWER_SUPPLY_TYPE_USB_CDP/POWER_SUPPLY_TYPE_USB_ACA，USB类型的供电，不同点在于充电电流的限制 (struct power_supply *psy); 其中power_supply_register和power_supply_register_no_ws的区别是：power_supply_register 2）PSY状态改变时通知power supply core的API 1: extern void power_supply_changed(struct power_supply *psy);
对外部提供对应接口） 其中，vm_bus的power_supply一般为struct power_supply *bms_psy; 而linear-charger则是struct power_supply usb_psy; （当然这只是一个命名方式而已了） power_supply具体参考这篇博客： Linux power supply class(1)_软件架构及API汇整【转】 struct power_supply (power_supply_class, NULL, psy,__power_supply_changed_work);对power_supply_class下的每个设备都进行匹配 --> __power_supply_changed_work , POWER_SUPPLY_PROP_CURRENT_NOW, POWER_SUPPLY_PROP_CURRENT_AVG, POWER_SUPPLY_PROP_POWER_NOW POWER_SUPPLY_PROP_MODEL_NAME, POWER_SUPPLY_PROP_MANUFACTURER, POWER_SUPPLY_PROP_SERIAL_NUMBER
首先驱动需要先获取到2个power supply kernel\msm-3.18\drivers\usb\phy\phy-msm-usb.c motg- usb_psy.name = "usb"; motg msm_otg_register_power_supply(pdev, motg)) psy = &motg- usb_psy; kernel\msm-3.18\drivers\power\bq2570x \bq2570x_charger.c usb_psy = power_supply_get_by_name("usb"); static int bq2570x_psy_register(struct 的power supply上报USB类型(CDP,DCP,USB) power_supply_set_supply_type(bq- usb_psy, POWER_SUPPLY_TYPE_USB); ret = power_supply_set_online(bq- usb_psy, true); power_supply_changed(bq- usb_psy); 充电动画的启动逻辑：POWER_SUPPLY_TYPE_BATTERY
区域划分 ---- Supply set：从1801 开始引入supply set 的概念，supply set 很像C++ 里的"类"，它将所有相关的supply nets "封装"起来，一个supply 且其值为空字符串，如 {} , 那只有-supply 指定的supply set 才可以为本power domain 所用； 如果用-available_supply 指定了某个具体的 supply set, 则该power domain 除了可以用由-supply 指定的supply set 也可以用由该option 指定的supply set. ? 的supply, 输出power supply 对应于load 的supply。 supply set level power state 的定义需要注意几点： -supply_expr 中只能包含该supply set 对应的net.
我们将为 列出一些用户 与用户登录 使用给定的代码创建以下文件 conftest.py-有一个fixture，可以为所有测试方法提供基本网址 导入pytest @ pytest.fixture def supply_url ): url = supply_url + "/users/50" resp = requests.get(url) assert resp.status_code == 404, resp.text import pytest import requests import json def test_login_valid(supply_url): url = supply_url + "/login ): url = supply_url + "/login/" data = {'email':'test@test.com'} resp = requests.post(url, data ): url = supply_url + "/login/" data = {} resp = requests.post(url, data=data) j = json.loads
power子系统主要由如下文件组成： power_supply.h (include\linux) power_supply_core.c (drivers\power) power_supply_sysfs.c power_supply { const char *name;//对应于/sys/class/power_supply/XXX 文件夹 enum power_supply_type )(struct power_supply *psy, enum power_supply_property psp, const union enum power_supply_property psp); //外部电源变化时所作的工作 void (*external_power_changed)(struct power_supply (struct power_supply *psy); power_supply_register函数 int power_supply_register(struct device *parent,

三、驱动 Android电源管理底层用的是Linux power_supply框架，内核提供给电池驱动的接口是结构体power_supply结构体。 struct power_supply { const char *name; enum power_supply_type type; enum power_supply_property *psy, enum power_supply_property psp, union power_supply_propval *val); int (*set_property)( struct power_supply *psy, enum power_supply_property psp, const union power_supply_propval *val (*external_power_changed)(struct power_supply *psy); void (*set_charged)(struct power_supply *psy)
原文题目：AI's Potential to Manage the Supply Chain 原文：Artificial intelligence has made noticeable changes Perhaps AI's most notable potential, however, is its role in the supply chain industry.AI has changed the supply chain process from reactive to proactive, which creates a larger change in how data-driven The first is automating repetitive tasks and processes across supply chain functions. That positions AI to be a vital tool.AI has tremendous potential to impact the global supply chain.
它有2个参数：Supply（单个数字）和Demands（一组数字，通常是一个Range对象）。 为了简单起见，Supply必须是单个数字>=0.0，并且Demands必须是单列垂直单元格区域或者数字数组。 VBA代码 下面是该函数的VBA代码： Option Base 1 Function MaxMinFair(Supply AsVariant, Demands As Variant) As Variant '数组函数,用于公平分配供给需求 'Supply必须是>=0.0的标量数字 'Demands必须是标量数字或者单个列区域或数据数组 Dim nUnsat As Long ) Then Supply = Supply.Value2 'Supply必须是一个>=0的标量数 If IsArray(Supply) Then GoTo FuncFail If Supply
