Hi, I'm trying to understand the MMU operations & am wondering where is the kernel code where the kernel interfaces with the this piece of hardware? Can some one help me in understanding that what all are the responsibilities of the kernel, and what is it the hardware takes care of automatically? E.g. who fills, flushes & refills the TLB entries? What all initializations need to be performed by kernel (And where is the code?)
