When does page fault occur?

A page fault occurs when a program accesses a memory page that is not currently in physical memory (RAM). This triggers the operating system to fetch the required page from secondary memory (disk) into RAM, allowing the program to continue execution.


What Actions are taken by operating system when page fault occurs?

the OS handles it by writing a page fault interrupt handler. The first thing the page fault handler will need to do is to determine the address of the page fault; you can find out this address by calling the Get_Page_Fault_Address() function (prototype in . Also, the errorCode field of theInterrupt_State data structure passed to the page fault interrupt handler contains information about the faulting access. This information is defined in the faultcode_t data type defined in. Once the fault address and fault code have been obtained, the page fault handler will need to determine an appropriate action to take

What is a page fault?

A page fault is an alert, such as an interrupt or exception, which indicates that a page of memory was accessed without being loaded.


How are page faults handled?

When a page fault occurs, the hardware cannot do anything else with the instruction that caused the page fault and thus it must transfer control to an operating system routine (this is the page fault handler). The page fault handler must then decide how to handle the page fault. It can do one of two things:- It can decide the virtual address is just simply not valid. In this case, Windows will report this error back by indicating an exception has occurred (typically STATUS_ACCESS_VIOLATION)- It can decide the virtual address is valid. In this case, Windows will find an available physical page, place the correct data in that page, update the virtual-to-physical page translation mechanism and then tell the hardware to retry the operation. When the hardware retries the operation it will find the page translation and continue operations as if nothing had actually happened.
