android用memtester内存压力测试_W歹匕示申W的博客-CSDN博客
Android内存压力测试工具(memtester移植)_甜牛奶蛋糕的博客-CSDN博客_android 内存压力测试
DRR参考配置OK之后，首先需要的是对DDR进行压力测试保证DDR的稳定性，否则DDR出问题之后，很容易引起奇奇怪怪的问题，很难分析问题原因
memtester说明：
memtester主要用于测试内存稳定性
官网：https://pyropus.ca./software/memtester/old-versions/
版本：memtester-4.3.0.tar.gz（目前最新版本-.10.21）
官方已经预编译了大部分Linux系统的二进制文件，可以直接使用，现在我们将它移植到Android系统中。
移植
首先我们看看Makefile文件它在Linux系统是怎么编译的，这里移植memtester-4.3.0.tar.gz压缩包里的文件不需要任何修改。
memtester: \$(OBJECTS) memtester.c tests.h tests.c tests.h conf-cc Makefile load extra-libs./load memtester tests.o `cat extra-libs`
从上面的Makefile可以知道，要编译memtester需要编译memtester.c和tests.c以及相关的头文件，所以我们可以写出下面的Android.mk文件。
LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_SRC_FILES := memtester.c tests.cLOCAL_C_INCLUDES := $(LOCAL_PATH)LOCAL_MODULE := memtesterinclude $(BUILD_EXECUTABLE)
memtester-4.3.0.tar.gz解压到system/core/目录下，并命名为memtester目录，并把Android.mk放到同一目录。文件如下显示。
~/project$ tar -zxvf memtester-4.3.0.tar.gz -C AndroidO_8827LGO_1207/system/core/~/project$ cd AndroidO_8827LGO_1207/system/core/memtester~/project/AndroidO_8827LGO_1207/system/core/memtester$tree.├── Android.mk├── BUGS├── CHANGELOG├── conf-cc├── conf-ld├── COPYING├── extra-libs.sh├── find-systype.sh├── make-compile.sh├── Makefile├── make-load.sh├── make-makelib.sh├── memtester.8├── memtester.c├── memtester.h├── README├── README.tests├── sizes.h├── tests.c├── tests.h├── trycpp.c├── types.h└── warn-auto.sh
先编译成模块进行测试：
~/project/AndroidO_8827LGO_1207/system/core/memtester$ mm -j8........5 warnings generated.[100% 6/6] Install: out/target/product/petrel-p1/system/bin/memtestermake: Leaving directory '/home/lemon/Develop/OrangePi_Lite2/android'#### make completed successfully ####
然后就可以通过
adb push memtester /system/bin/adb shell "chmod 777 /system/bin/memtester"adb shell memtester
最后添加到device.mk中，系统全编译时打包到系统，所以还需要在device.mk里面进行定义
PRODUCT_PACKAGES += memtester
测试
使用方法：Usage: memtester [-p physaddrbase [-d device]] [B|K|M|G] [loops]，比如memtester 5M 1，对应测试1次5M内存

查看系统空闲内存，还有251M

演示：memtester 5M 1，这里只是演示，测试1次5M内存，实际项目中这两个参数应尽可能大，才能覆盖整块内存，才能达到压力测试的结果，测试时失败有相应的log，我这里比较难复现就不贴了。

APK预置到代码里面给个系统权限：
Android.mkLOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_MODULE_TAGS := optionalLOCAL_CERTIFICATE := platformLOCAL_SRC_FILES := $(call all-java-files-under, src)LOCAL_SDK_VERSION := currentLOCAL_PACKAGE_NAME := ddrinclude $(BUILD_PACKAGE)# Use the following include to make our test apk.include $(call all-makefiles-under,$(LOCAL_PATH))配置文件配置手机UID权限：<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="/apk/res/android"package="com.example.memtester_ckt"android:versionCode="1"android:versionName="1.0"android:sharedUserId="android.uid.system"><uses-sdkandroid:minSdkVersion="14"android:targetSdkVersion="21" /><applicationandroid:allowBackup="true"android:icon="@drawable/ic_launcher"android:label="@string/app_name"android:theme="@style/AppTheme" ><activityandroid:name=".MainActivity"android:label="@string/app_name" ><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity></application></manifest>
把文件用android代码预置到手机system/bin下面，也就给手机配置了脚本环境：
CSH_DDR_PATH := packages/apps/ddr/assetsPRODUCT_COPY_FILES := $(CSH_DDR_PATH)/memtester:system/bin/memtester $(PRODUCT_COPY_FILES)

运行这个脚本：
sh memory.sh -c <number> -l <number> -m <memory>
-c:运行几个memtester
-l:运行几次
-m:测试多大的内存，直接填测试总数即可，程序会自动分配个平均值给每个memtester，这样省去我们自己的计算，也不用多开几个终端了，单位MB，例如我有一个四核CPU，32G 内存的机器，就可以这样运行：
sh memory.sh -c 4 -l 1 -m 3100
大家可以看这个脚本中还可以限定时间，例如我想运行24个小时
sh memory.sh -t 24h -c 4 -m 3100
