Hi, Thanks Felix for your quick reply.
Actually we are doing an academic project in which we need to have two cores of Intel Core 2 Duo, running inside the GRUB simultaneously. For that we need to send an IPI from primary core to the secondary core. Can you suggest any pointers to implement this? Has someone done anything similar to this before? Thanks in advance, Swapnil Pimpale.
