Hello: Is there method to check the registers viaration info before and after one special system call for one thread with the help of JDB. I checked all the options but i can't find one. What i want to know is about the l4_thread_ex_regs system call. We know it could modify the instruction pointer, stack pointer and pager thread or get the current instruction pointer, stack pointer and pager thread. When we modify the instruction pointer to a new one but put the stack pointer the same i want to understand what happens in this thread stack. Thanks. cheng guanghui
