篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Qcom rampdump解析工具使用相关的知识,希望对你有一定的参考价值。
使用如下命令获取qcom工具:
[email protected]:~/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:

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
