I want to know what kernel idle thread does. Does it just execute "halt" instruction or anything else?

Mostly it is calling a halt instruction but it can also do remote work.

Where is code for the idle thread?

Please look for 'for (;;) idle_op()' in kernel_thread.cpp and app_cpu_thread.cpp. Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/
