[DESCRIPTION]
      大家在分析performance问题时，经常需要boost CPU/GPU/DRAM、关闭FPSGO/Thermal、对比Display资讯，本FAQ提供常用的debug命令以供参考。

[SOLUTION]

2.        adb shell "echo 0 0 > /proc/ppm/policy/ut_fix_freq_idx"
   
3. 
   
4.        Fix cluster0 cores max frequency, some chip's L core is cluster0, some chip's L core is cluster1.
   
5.        adb shell "echo -1 0 > /proc/ppm/policy/ut_fix_freq_idx"
   
6. 
   
7.        Fix cluster1 cores max frequency
   
8.        adb shell "echo 0 -1 > /proc/ppm/policy/ut_fix_freq_idx"
   
9. 
   
10.        Get L & LL cores frequency
    
11.        adb shell "cat /proc/cpufreq/MT_CPU_DVFS_L/cpufreq_freq"
    
12.        adb shell "cat /proc/cpufreq/MT_CPU_DVFS_LL/cpufreq_freq"
    
13. 
    
14.        Get L & LL cores opp table
    
15.        adb shell "cat /proc/cpufreq/MT_CPU_DVFS_L/cpufreq_oppidx"
    
16.        adb shell "cat /proc/cpufreq/MT_CPU_DVFS_LL/cpufreq_oppidx"
    
17. 
    
18.        Check current eas status
    
19.        adb shell "cat /sys/devices/system/cpu/eas/info"
    
20. 
    
21.        关闭cluster0 cores
    
22.        adb shell "echo 0 4 > /proc/ppm/policy/ut_fix_core_num"
    
23. 
    
24.        More CPU Commands can refer to FAQ21818.

2. Command - GPU
       GPU相关debug指令
       adb root

1.        Get frequency table
   
2.        adb shell "cat /proc/gpufreq/gpufreq_opp_dump"
   
3. 
   
4.        Fix frequency, the frequency sbould in gpufreq_opp_dump
   
5.        adb shell "echo ***000 > /proc/gpufreq/gpufreq_opp_freq"
   
6. 
   
7.        Check current frequency:
   
8.        adb shell "cat /proc/gpufreq/gpufreq_var_dump"
   
9. 
   
10.        定GPU天花板OPP档位
    
11.        adb shell "echo 1 > /d/ged/hal/custom_upbound_gpu_freq"

3. Command - DRAM
       VCORE相关debug指令
       adb root

1.        Force VCORE DVFS
   
2.        adb shell "echo 0 > /sys/devices/platform/10012000.dvfsrc/helio-dvfsrc/dvfsrc_force_vcore_dvfs_opp" //0档表示最高频率
   
3. 
   
4.        Check VCORE current status
   
5.        adb shell "while true; do (sleep 1; cat /sys/devices/platform/10012000.dvfsrc/helio-dvfsrc/dvfsrc_dump | grep -e uv -e khz -e REQ -e DVFSRC_SW_REQ ; echo ===========================); done"
   

复制代码

1.        Get OPP table
   
2.        adb shell "cat /sys/devices/platform/10012000.dvfsrc/helio-dvfsrc/dvfsrc_opp_table"
   
3. 
   
4.        Check if VCORE DVFS is enabled
   
5.        adb shell "cat /sys/devices/platform/10012000.dvfsrc/helio-dvfsrc/dvfsrc_enable"
