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‘... remote: Counting objects: 7400, done. remote: Compressing objects: 100% (550/550), done. remote: Total 7400 (delta 315), reused 0 (delta 0) 接收对象中: 100% (7400/7400), 1.18 MiB | 0 bytes/s, 完成. 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

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

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
