Android 如何修复未知字段'；暂停'；编译smartass调控器时在初始值设定项中指定？

我一直在试图弄清楚为什么当我试图编译我的android内核时，smarts governor会出现以下错误：

drivers/cpufreq/cpufreq_smartass2.c:844:2: error: unknown field 'suspend' specified in initializer
      .suspend = smartass_early_suspend,
      ^
    drivers/cpufreq/cpufreq_smartass2.c:844:13: warning: excess elements in struct initializer
    error, forbidden warning: cpufreq_smartass2.c:844
    make[2]: *** [drivers/cpufreq/cpufreq_smartass2.o] Error 1
    make[1]: *** [drivers/cpufreq] Error 2
    make: *** [drivers] Error 2
    make: *** Waiting for unfinished jobs....

我检查了给出错误的行，这是一个初始化的变量，它是一个结构数据结构的成员。代码如下：

static struct early_suspend smartass_power_suspend = {
        .suspend = smartass_early_suspend,
        .resume = smartass_late_resume,
    #ifdef CONFIG_MACH_HERO
        .level = EARLY_SUSPEND_LEVEL_DISABLE_FB + 1,
    #endif
    };

以下是完整代码：

static void smartass_suspend(int cpu, int suspend)
{
    struct smartass_info_s *this_smartass = &per_cpu(smartass_info, smp_processor_id());
    struct cpufreq_policy *policy = this_smartass->cur_policy;
    unsigned int new_freq;

    if (!this_smartass->enable)
        return;

    smartass_update_min_max(this_smartass,policy,suspend);
    if (!suspend) { // resume at max speed:
        new_freq = validate_freq(policy,sleep_wakeup_freq);

        dprintk(SMARTASS_DEBUG_JUMPS,"SmartassS: awaking at %d\n",new_freq);
        __cpufreq_driver_target(policy, new_freq,
                    CPUFREQ_RELATION_L);
    } else {
        // to avoid wakeup issues with quick sleep/wakeup don't change actual frequency when entering sleep
        // to allow some time to settle down. Instead we just reset our statistics (and reset the timer).
        // Eventually, the timer will adjust the frequency if necessary.

        this_smartass->freq_change_time_in_idle =
            get_cpu_idle_time_us(cpu,&this_smartass->freq_change_time);

        dprintk(SMARTASS_DEBUG_JUMPS,"SmartassS: suspending at %d\n",policy->cur);
    }

    reset_timer(smp_processor_id(),this_smartass);
}

static void smartass_early_suspend(struct early_suspend *handler) {
    int i;
    if (suspended || sleep_ideal_freq==0) // disable behavior for sleep_ideal_freq==0
        return;
    suspended = 1;
    for_each_online_cpu(i)
        smartass_suspend(i,1);
}

static void smartass_late_resume(struct early_suspend *handler) {
    int i;
    if (!suspended) // already not suspended so nothing to do
        return;
    suspended = 0;
    for_each_online_cpu(i)
        smartass_suspend(i,0);
}

static struct early_suspend smartass_power_suspend = {
    .suspend = smartass_early_suspend,
    .resume = smartass_late_resume,
#ifdef CONFIG_MACH_HERO
    .level = EARLY_SUSPEND_LEVEL_DISABLE_FB + 1,
#endif
};

代码在语法上似乎是正确的，我遇到了这个问题。有人能帮忙吗？

多亏了@Tsyvarev，我解决了“初始化器中指定的未知字段‘suspend’的问题”

在尝试添加其他调控器并尝试编译之后，我收到我添加的新调控器的此错误消息

drivers/built-in.o: In function cpufreq_smartass_init':
/home/nick/android/LGD722LKernel/drivers/cpufreq/cpufreq_smartass2.c:898: undefined reference to `register_early_suspend'

我已经检查了函数寄存器_eary _suspend，它的调用方式和参数传递给函数的方式看起来是正确的。我想它可能是来自makefile，但这只是我的观点。如果有人对这个问题有任何其他想法，请分享我在内核开发方面没有太多经验，你的想法/建议会对我很有帮助。

你能展示一下

struct early\u suspend

的定义吗？错误消息说此结构没有名为

suspend

的成员。找到它：

CONFIG\u HAS\u EARLYSUSPEND

的值是多少？我四处查看了一下，它没有用值初始化。它被设置为#define，即defined（CONFIG_HAS_EARLYSUSPEND）它被定义了吗？你确定吗？它看起来像一个内核配置选项，是否在配置中设置？将

\ifndef CONFIG\u HAS#EARLYSUSPEND#error“oops”#endif

和每个

一起添加到该文件的某个新行中，然后再次编译。我使用配置的初始化搜索函数查看我的git\u HAS#EARLYSUSPEND没有看到类似的内容。
