How to find which task is running on a particular core at a given intstance
I am using Kernel 188.8.131.52
I have to find on which core a particular task is running on .
I am ready to modify the kernel to do printk or some logging .
I guess there used to be 2 fields called 'processor' and 'last_processor' in task_struct in older kernels which probably had this information .
So what do I do to find out on which core a particular task is running on ?
Are there any utilities that are simple-to-use and can display the tasks that are running on each of the cores , including the cpu core info ? top , mpstat etc do not tell you on which cpu core a task is running on .

Almost positive this is impossible and that both cores simultaneously share tasks. Almost ten years of linux and I've never seen this type of softwareBodhi 1.3 & Bodhi 1.4 using E17
