蓝天笔记本风扇调速

蓝天笔记本调速工具,支持 CPU/GPU

修改自下列项目

• https://github.com/davidrohr/clevo-indicator
• https://github.com/SkyLandTW/clevo-indicator

做了以下修改

• 已解锁 GUI 手工调速下限为 40%
• 汉化了说明,挖掘了更多参数

构建/Build

# For Ubuntu/Debian
sudo apt install libappindicator3-dev libgtk-3-dev
git clone https://github.com/gzzchh/clevo-indicator
cd clevo-indicator
make install

# For CentOS/Fedora
sudo dnf install \
libappindicator-gtk3-devel \
libappindicator-gtk3 \
libappindicator \
libappindicator-devel
git clone https://github.com/gzzchh/clevo-indicator
cd clevo-indicator
make install

用法/Usage

clevo-indicator set [fan-duty-percentage(int)] 设定 CPU 风扇百分比
clevo-indicator setg [fan-duty-percentage(int)] 设定 GPU 风扇百分比
clevo-indicator help 打印帮助
clevo-indicator dump 获取温度
clevo-indicator dumpall 获取温度(原始数据)
clevo-indicator auto 自动设定风扇速度并退出(适合定时脚本)
clevo-indicator indicator 显示调速 GUI

fan-duty-percentage 是一个 int
指定风扇百分比

笔记/Note

简单来说调用 EC 接口需要 root 权限
但是一般 Linux 桌面都是给普通用户的
所以你需要 setuid

操作方法如下

sudo chown root clevo-indicator
sudo chmod u+s  clevo-indicator

本程序与任何通过低级调用访问 EC 的程序冲突,可能会发生未知的行为
本程序也没有对 EC 访问做保护

The executable has setuid flag on, but must be run by the current desktop user, because only the desktop user is allowed to display a desktop indicator in Ubuntu, while a non-root user is not allowed to control Clevo EC by low-level IO ports. The setuid=root creates a special situation in which this program can fork itself and run under two users (one for desktop/indicator and the other for EC control), so you could see two processes in ps, and killing either one of them would immediately terminate the other.

Be careful not to use any other program accessing the EC by low-level IO syscalls (inb/outb) at the same time - I don't know what might happen, since every EC actions require multiple commands to be issued in correct sequence and there is no kernel-level protection to ensure each action must be completed before other actions can be performed... The program also attempts to prevent abortion while issuing commands by catching all termination signals except SIGKILL - don't kill the indicator by "kill -9" unless absolutely necessary.

修改/Hack

如果想要给 GUI 菜单添加更多的选项,可以去 clevo-indicator.c 第 138 行左右
找到一个数组,然后 Just Copy

static menuitems[] = {
    {"Set FAN to AUTO", G_CALLBACK(ui_command_set_fan), 0, AUTO, NULL},
    {"", NULL, 0L, NA, NULL},
    {"Set FAN to  40%", G_CALLBACK(ui_command_set_fan), 40, MANUAL, NULL},
    {"Set FAN to  50%", G_CALLBACK(ui_command_set_fan), 50, MANUAL, NULL},
    {"Set FAN to  60%", G_CALLBACK(ui_command_set_fan), 60, MANUAL, NULL},
    {"Set FAN to  70%", G_CALLBACK(ui_command_set_fan), 70, MANUAL, NULL},
    {"Set FAN to  80%", G_CALLBACK(ui_command_set_fan), 80, MANUAL, NULL},
    {"Set FAN to  90%", G_CALLBACK(ui_command_set_fan), 90, MANUAL, NULL},
    {"Set FAN to 100%", G_CALLBACK(ui_command_set_fan), 100, MANUAL, NULL},
    {"", NULL, 0L, NA, NULL},
    {"Quit", G_CALLBACK(ui_command_quit), 0L, NA, NULL}};

关于百分比计算规则,目前是放在 clevo-indicator.c 第 884 行左右,如下

static int ec_auto_duty_adjust(void)
{
    int temp = MAX(share_info->cpu_temp, share_info->gpu_temp);
    int duty = share_info->fan_duty;
    //
    if (temp >= 80 && duty < 100)
        return 100;
    // 篇幅关系 省略大部分
    //
    return 0;
}
