Hi, I would like to write a kernel module that will induce the softlockup and hardlockup on the cpu core(s). Below is my logic and was wondering if some one can help me verify and guide me creating a thread and other stuff for implementing the logic.
softlockup: on given cpu number. 1. disable kernel preemption 2. keep looping for 21 seconds (as per kernel Documentation it takes 20 seconds to detect and I would like to recover the system once its detected). 3. release the cpu hardlockup on given cpu number. 1. disable interrrupts. 2. keep looping for 11 seconds. 3. enable interrupts and release cpu. Regards, Vipul.
