查找使用了rdcycle汇编指令的软件包 #837

Closed laokz closed 2 months ago

laokz commented 3 months ago

由于opensbi和内核升级，2403上用户空间执行rdcycle指令将导致非法指令错误。调查2403上的6000余包中有哪些还使用了该指令。一般思路提示：

wzssyqa commented 3 months ago

给个思路，下载所有的二进制包，解开，搜索其中的.a/.so 以及其他elf文件。 反汇编，grep rdcycle。

这种能解决大部分问题，还有一部分类似JIT的情况，需要另外想办法。

大佬就是大佬 牛！ 这些问题怎么解决看来还得琢磨琢磨，有的不是源码嵌入了这个指令，，
