The goal of this assignment to understand the paging subsystem of an operating system. The first component you need to implement is demand paging. Demand paging lazily maps a physical page corresponding to a virtual page during the time of dereferencing. In addition to demand paging, you also need to implement swapping. If the system runs out of physical memory, then the swapping subsystem reuse an already used physical page by saving its contents to secondary storage (e.g., disk).

For this assignment, you need to install qemu.
Run
sudo apt-get install qemu
Please clone the assignment repo from https://github.com/Systems-IIITD/
xv6-paging.git.
Run
make qemu
It will boot the xv6 OS in qemu emulator. You can also redirect the output to
a file using, make qemu > log.txt.
The default process is the shell. Type memtest1 to run memtest1.
Currently ( Ours does not :) ), it panics because the page fault handler is not implemented. After, you have correctly implemented everything, memtest1 and memtest2 should run normally
