Hi I see it's you again ;) Your code is buggy. I am really sorry if I am missing something. The problem I had mentioned earlier was different. This problem is might be a narrowed version of earlier problem. The code is actually onlye 10 lines. 1. For the first case in which I put kernel thread in infinite loop on a multiprocessor machine the code is module_init() { int i,j,k; while (1); return 0; } 2. For second case it is extern unsigned int jiffies; module_init() { int i,j,k; unsigned int current=jiffies; while (jiffies - current < 10000) printk(" ###############"); return 0; } Please let me know what is the bug in this code. |
