该驱动是否不支持编译到内核工作
Opened this issue · 4 comments
我用-y的方式把驱动编译到内核里了，dev/里存在rwProcMem37驱动，lsmod里没有
我尝试了OpenProcess发现能正常与驱动通信，但是read和write会失败，我查看了一下源码实现，代码中在读写时并没有用到控制码，而是用的
ssize_t realRead = read(nDriverLink, buf, nSize);
我查看了一下驱动中读写时用到了这个结构体
MY_STATIC const struct my_file_operations rwProcMem_fops =
{
.owner = THIS_MODULE,
.llseek = rwProcMem_llseek,
.read = rwProcMem_read,
.write = rwProcMem_write,
}
貌似驱动读写时需要 THIS_MODULE
是否用这种方式读写只能以-m的方式编译驱动？
补充一下，我的内核版本是5.15
测试完了，未兼容5.15
