Hi, I have question regarding the physical memory allocation for the kernel code and data. During the initialization of the system, the kernel page tables are created and a one to one mapping of the linear addresses starting from (0xC0000000)to the physical addresses(starting at 0x00000000, correct me if I'm wrong)is created. My question is will these pages always be in memory ? Thanks Rithin. -- Kernelnewbies: Help each other learn about the Linux kernel.
