Hi,
I'm looking at a specific IOCTL SET_CONTEXT_MANAGER of binder driver
initiated by service manager.
int binder_become_context_manager(struct binder_state *bs)
{
return ioctl(bs->fd, BINDER_SET_CONTEXT_MGR, 0);
}
control flows from the ioctl call to the following function.
static long binder_ioctl(struct file *filp, unsigned int cmd, unsigned
long arg)
{
}
ioctl basically invokes the system call __ioctl. But i'm not able to
find the implemenation of __ioctl. I want to have a look at the
generation of software interrupt and values stored in registers. Can
someone point at the relevant code?
