DRR參考配置OK之後，首先需要的是對DDR進行壓力測試保證DDR的穩定性，否則DDR出問題之後，很容易引起奇奇怪怪的問題，很難分析問題原因

memtester說明：

memtester主要用於測試內存穩定性
官網：http://pyropus.ca/software/memtester/
版本：memtester-4.3.0.tar.gz（目前最新版本-2018.10.21）
官方已經預編譯了大部分Linux系統的二進制文件，可以直接使用，現在我們將它移植到Android系統中。
 

移植

首先我們看看Makefile文件它在Linux系統是怎麼編譯的，這裏移植memtester-4.3.0.tar.gz壓縮包裏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`

從上面的Makefile可以知道，要編譯memtester需要編譯memtester.c和tests.c以及相關的頭文件，所以我們可以寫出下面的Android.mk文件。

​LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := memtester.c tests.c
LOCAL_C_INCLUDES := $(LOCAL_PATH)
LOCAL_MODULE := memtester
include $(BUILD_EXECUTABLE)

memtester-4.3.0.tar.gz解壓到system/core/目錄下，並命名爲memtester目錄，並把Android.mk放到同一目錄。文件如下顯示。

~/project$ tar -zxvf memtester-4.3.0.tar.gz -C AndroidO_8827LGO_20181207/system/core/
~/project$ cd AndroidO_8827LGO_20181207/system/core/memtester
~/project/AndroidO_8827LGO_20181207/system/core/memtester$tree
.
├── Android.mk
├── BUGS
├── CHANGELOG
├── conf-cc
├── conf-ld
├── COPYING

├── find-systype.sh

├── memtester.h
├── README
├── README.tests
├── sizes.h
├── tests.c
├── tests.h
├── trycpp.c
├── types.h
└── warn-auto.sh

先編譯成模塊進行測試：

~/project/AndroidO_8827LGO_20181207/system/core/memtester$ mm -j8
........
5 warnings generated.
[100% 6/6] Install: out/target/product/petrel-p1/system/bin/memtester
make: Leaving directory '/home/lemon/Develop/OrangePi_Lite2/android'


#### make completed successfully ####

然後就可以通過

adb push memtester /system/bin/
adb shell "chmod 777 /system/bin/memtester"
adb shell memtester 

最後添加到device.mk中，系統全編譯時打包到系統，所以還需要在device.mk裏面進行定義

PRODUCT_PACKAGES += memtester

測試

使用方法：Usage: memtester [-p physaddrbase [-d device]] [B|K|M|G] [loops]，比如memtester 5M 1，對應測試1次5M內存

PS C:\Users\zhaojr\Documents\adb> ./adb root
adbd is already running as root
PS C:\Users\zhaojr\Documents\adb> ./adb remount
remount succeeded
PS C:\Users\zhaojr\Documents\adb> ./adb shell

查看系統空閒內存，還有251M

演示：memtester 5M 1，這裏只是演示，測試1次5M內存，實際項目中這兩個參數應儘可能大，才能覆蓋整塊內存，才能達到壓力測試的結果，測試時失敗有相應的log，我這裏比較難復現就不貼了。

8227LGO_demo:/ # memtester 5M 1

APK預置到代碼裏面給個系統權限：

Android.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_CERTIFICATE := platform
LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_SDK_VERSION := current
LOCAL_PACKAGE_NAME := ddr
include $(BUILD_PACKAGE)
# Use the following include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))

配置文件配置手機UID權限：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.memtester_ckt"
    android:versionCode="1"
    android:versionName="1.0"
android:sharedUserId="android.uid.system">

    <uses-sdk
        android:minSdkVersion="14"
        android:targetSdkVersion="21" />
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"

            </intent-filter>
        </activity>
    </application>
</manifest>

把文件用android代碼預置到手機system/bin下面，也就給手機配置了腳本環境：

CSH_DDR_PATH := packages/apps/ddr/assets
PRODUCT_COPY_FILES := $(CSH_DDR_PATH)/memtester:system/bin/memtester $(PRODUCT_COPY_FILES)

運行這個腳本：

sh memory.sh -c <number> -l <number> -m <memory>

-c:運行幾個memtester

-l:運行幾次

-m:測試多大的內存，直接填測試總數即可，程序會自動分配個平均值給每個memtester，這樣省去我們自己的計算，也不用多開幾個終端了，單位MB，例如我有一個四核CPU，32G 內存的機器，就可以這樣運行：

sh memory.sh -c 4 -l 1 -m 3100

大家可以看這個腳本中還可以限定時間，例如我想運行24個小時

sh memory.sh -t 24h -c 4 -m 3100
