修改測試apk讀出的CPU主頻

修改系統在sys下面的頻率顯示，在/drivers/cpufreq/cpufreq.c

/**

 * cpufreq_per_cpu_attr_read() / show_##file_name() -

 * print out cpufreq information

 *

 * Write out information from cpufreq_driver->policy[cpu]; object must be

 * "unsigned int".

 */

#define show_one(file_name, object) \

static ssize_t show_##file_name \

(struct cpufreq_policy *policy, char *buf) \

{ \

return sprintf(buf, "%u\n", policy->object); \

}

#define show_change(file_name, object) \

static ssize_t show_##file_name \

(unsigned int val, char *buf) \

{ \

return sprintf(buf, "%u\n", 1200000); \

}

show_one(cpuinfo_min_freq, cpuinfo.min_freq);

//show_one(cpuinfo_max_freq, cpuinfo.max_freq);

show_change(cpuinfo_max_freq, cpuinfo.max_freq);  //change by azad  for change the freq

show_one(cpuinfo_transition_latency, cpuinfo.transition_latency);

show_one(scaling_min_freq, min);

show_one(scaling_max_freq, max);

//show_one(scaling_cur_freq, cur);

show_change(scaling_cur_freq, cur);

cpuinfo.max_freq  系統的最大頻率

scaling_cur_freq     系統當前的頻率

修改這兩個頻率的的接口，不從系統中讀取，直接寫死
