What is page fault? Its types.One of the critical parts of code in the Linux kernel. It has a major influence on memory subsystem’s performance. A process has a page table, also called as map that contains page table entries that points to the assigned memory to the process and communicates to the CPU, the memory locations which are valid for accessing a process. Each process is assigned to a memory chunk named as pages. A page table that is does not map memory area access, will result in generation of page fault by CPU.
