Qcom rampdump解析工具使用

使用如下命令获取qcom工具：

ljj@ljj-ThinkCentre-M83:~/git/qcom_tools/ramdump$ git clone git://codeaurora.org/quic/la/platform/vendor/qcom-opensource/tools
正克隆到 'tools'...

处理 delta 中: 100% (5365/5365), 完成.
检查连接... 完成。

　　

将如下内容保存成shell脚本至/home/ljj/shared/tools/ 路径下，加入环境变量（~/.bashrc中，加入一行：export PATH=/home/ljj/shared/tools/:$PATH）。（其中force-hardware sdm845，可以根据平台不同修改命令）。

中间文件的路径是在code源码路径下（这个是64位的，32位的现在还有平台用么？）：

gdb：prebuilts/gdb/linux-x86/bin

nm：prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin

objdump：prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin

# ramdump-parser.sh
 
#! /bin/bash
echo ""
echo "Start ramdump parser.."

echo ""
exit 0

　　

另外，针对sdm845平台的解析脚本，一定要创建一个local_settings.py，在ramparse.py同一级目录下。因为脚本中会import，避免报错（这个里面其实可以随便写，因为它也是为了提供gdb等工具的路径变量的）

gdb64_path = "gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin/aarch64-linux-android-gdb"
nm64_path = "gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin/aarch64-linux-android-nm"
objdump64_path = "gcc/linux-x86/aarch64/aarch64-linux-android4.9/bin/aarch64-linux-android-objdump"

'''
gdb_path - absolute path to the gdb tool for the ramdumps
nm_path - absolute path to the gdb tool for the ramdumps
gdb64_path - absolute path to the 64-bit gdb tool for the ramdumps
nm64_path - absolute path to the 64-bit nm tool for the ramdumps
'''

　

将vmlinux放到 ramdump文件夹内，然后在ramdump文件的目录下执行命令：

ljj@ljj-ThinkCentre-M83:~/shared/#504/ramdump$ ramdunmp-parser.sh 

Start ramdump parser..
cd /home/ljj/git/qcom_tools/ramdump/tools-2/tools/linux-ramdump-parser-v2

python ramparse.py -v /home/ljj/shared/#504/ramdump/vmlinux -g /media/ljj/2T/IME/prebuilts/gdb/linux-x86/bin/gdb  -n /home/ljj/tools/gnu-tools/aarch64-linux-android-4.9/bin/aarch64-linux-android-nm  -j /home/ljj/tools/gnu-tools/aarch64-linux-android-4.9/bin/aarch64-linux-android-objdump -a /home/ljj/shared/#504/ramdump/ -o /home/ljj/shared/#504/ramdump/out -x

out: /home/ljj/shared/#504/ramdump/out

可以在目录下找到out文件夹，其中就是解析出来的文件。

然后接下来才是最痛苦的，泡杯茶，吃颗糖，慢慢看吧~ XD
