Your main routine shall generate a random page trace of length n, where the page numbers have values ranging from 0 to ? − 1. Develop a subroutine within your program that implements the FIFO page replacement algorithm (as a separate function within your program). The function shall accept a page trace and a parameter f for the number of frames allocated. Your main routine shall then apply the random page trace to the subroutine implementing the page replacement algorithm, multiple times (using only one trace, randomly generated), passing a parameter f (number of page frames used) that ranges from 4 to k. Your main routine shall then record the number of page faults for each run (i.e. for each f).Run your program using a page…PROVIDE THE SOURCE CODE FOR LINUX C WITH OUTPUT Write a program to implement page replacement technique.

The kernel maintains a list of messages. To limit memory usage, we impose a limit of 4KB = 4*1024 bytes for each message and also impose a limit of the total number of messages stored in the kernel, which is 1000. Your device driver should perform the following operations: * When the module is loaded, the device is created. An empty list of messages is created as well. * Removing the module deallocates all messages, removes the list of messages and removes the device. * Reading from the device returns one message, and removes this message from the kernel list. If the list of messages is empty, the reader returns -EAGAIN. * Writing to the device stores the message in kernel space and adds it to the list if the message is below the maximum size, and the limit of the number of all messages stored in the kernel wouldn't be surpassed with this message. If the message is too big, -EINVAL is…
