文摘 Android MediaTek 2020-10-5 阅读:326

[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]

 1. Command - CPU
       CPU相关debug指令
       adb root

       Fix L & LL cores max frequency:
       adb shell "echo 0 0 > /proc/ppm/policy/ut_fix_freq_idx"

       Fix cluster0 cores max frequency, some chip's L core is cluster0, some chip's L core is cluster1.
       adb shell "echo -1 0 > /proc/ppm/policy/ut_fix_freq_idx"

       Fix cluster1 cores max frequency
       adb shell "echo 0 -1 > /proc/ppm/policy/ut_fix_freq_idx"

       Get L & LL cores frequency
       adb shell "cat /proc/cpufreq/MT_CPU_DVFS_L/cpufreq_freq"
       adb shell "cat /proc/cpufreq/MT_CPU_DVFS_LL/cpufreq_freq"

       Get L & LL cores opp table
       adb shell "cat /proc/cpufreq/MT_CPU_DVFS_L/cpufreq_oppidx"
       adb shell "cat /proc/cpufreq/MT_CPU_DVFS_LL/cpufreq_oppidx"

       Check current eas status
       adb shell "cat /sys/devices/system/cpu/eas/info"

       关闭cluster0 cores
       adb shell "echo 0 4 > /proc/ppm/policy/ut_fix_core_num"

       More CPU Commands can refer to FAQ21818.

 2. Command - GPU
       GPU相关debug指令
       adb root

       Get frequency table
       adb shell "cat /proc/gpufreq/gpufreq_opp_dump"

       Fix frequency, the frequency sbould in gpufreq_opp_dump
       adb shell "echo *000 > /proc/gpufreq/gpufreq_opp_freq"

       Check current frequency:
       adb shell "cat /proc/gpufreq/gpufreq_var_dump"

       定GPU天花板OPP档位
       adb shell "echo 1 > /d/ged/hal/custom_upbound_gpu_freq"

 3. Command - DRAM
       VCORE相关debug指令
       adb root

       Force VCORE DVFS
       adb shell "echo 0 > /sys/devices/platform/10012000.dvfsrc/helio-dvfsrc/dvfsrc_force_vcore_dvfs_opp" //0档表示最高频率

       Check VCORE current status
       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"

       Get OPP table
       adb shell "cat /sys/devices/platform/10012000.dvfsrc/helio-dvfsrc/dvfsrc_opp_table"

       Check if VCORE DVFS is enabled
       adb shell "cat /sys/devices/platform/10012000.dvfsrc/helio-dvfsrc/dvfsrc_enable"

 4. Command - FPSGO
       FPSGO开关指令
       adb root

       Check FPSGO enabled
       adb shell "cat /sys/kernel/debug/fpsgo/common/fpsgo_enable"

       Disable FPSGO
       adb shell "echo 0 > /sys/kernel/debug/fpsgo/common/force_onoff"

       Enable FPSGO
       adb shell "echo 1 > /sys/kernel/debug/fpsgo/common/force_onoff"

       Check target fps
       adb shell "cat /sys/kernel/debug/fpsgo/fstb/fpsgo_status"

 5. Command - Thermal
       Thermal开关指令
       adb root

       Disable thermal
       adb shell "thermal_manager /vendor/etc/.tp/.ht120.mtc"

       Enable thermal policy
       adb shell "thermal_manager vendor/etc/.tp/thermal.conf"

       查看当前thermal policy
       adb shell "cat /data/vendor/.tp/.settings"
       android O之前的版本,使用的节点是/data/.tp/.settings
       adb shell "cat /data/.tp/.settings"

       查看当前thermal policy下的threshold
       adb shell "cat /proc/driver/thermal/clctm"

       Some thermal test of old android version can refer to FAQ15144

 6. Display相关指令
       检查解析度 & Buffer slots资讯
       adb shell "dumpsys SurfaceFlinger" > sf1.log

       change window size command
       adb shell "wm size 720x1560"

       Reset window size command
       adb shell wm size reset
