解析天启rk3288源码 /kernel/drivers/char/virtd

virtd为编译后产生的中间文件,可使用ELF格式逆向


1、ELF文件内容解析
readelf: 可解析ELF文件的所有内容;
strings: 查看ELF文件中的字符串;
file   : 查看ELF文件的信息;
nm     : 查看ELF文件中的符号信息;
ldd    : 查看ELF文件所依赖的库文件;

2、objdump
用于对ELF文件进行反汇编;
objdump -d  ;反汇编部分可执行的二进制代码;
objdump -D  ;反汇编全部的可执行的二进制代码;
objdump -S  ;尽量把可执行的二进制代码反汇编成源码;

3、hexdump
以十六进制格式查看ELF格式的二进制可执行文件的内容;
hexdump -C elf_file_name

 

readelf -a virtd

发现一段字符串是 ret %d
跟日志打印吻合,ret 1024,为了查找这个原始打印也废了很大劲

我们可以根据里边的函数名称,去找kernel中哪些文件使用过这些函数,并去git还原老版本,估计关联很多。

未解决。。。。。。。。

待续

 

 

先暴力恢复老版本,等以后有空了再适配

git reset --hard f5535b6cbc2264aacf9927a95490ae10b00c4fb7
重新编译烧录就可以正常启动android

 

但还是有几点疑惑:

1. 为什么其他型号的rk3288烧录最新系统会卡在内核驱动初始化,天启自己的rk3288w 1650批次的没问题,但是其他rk3288w 1652 等以后生产的都不行

2. 为什么出问题系统都会卡在这里drm_misc_init,kernel/drivers/char/virtd这个文件到底是为了优化什么功能的,为什么天启不提供源文件,国内都是这样的开源?
