Trap to the operating system, operating system decides the trap a page fault, and check that the page reference is Invalid reference or Just not in memory f. Wait for the device seek and/or latency time g. Find a free frame, if there is a free frame, use it; h. While waiting, allocate the CPU to some other user i. Receive an interrupt from the disk I/O subsystem (I/O completed) j. Save the registers and process state for the other user k. Save the user registers and process state for the page fault process, l. Restore the user registers, process state, and new page table, and then resume the interrupted instruction m. Issue a read from the disk to a free frame. n. Wait for the CPU to be allocated to this process again o. Determine that the interrupt was from the disk p. Begin the transfer of the page to a free frame q. If there is no free frame, use a page replacement algorithm to select a victim frame Please write the correct execution order. (15 points)
