  5. You Need Virtual Machines

  6. How to Use ?

  7. It’s Your Job

  8. Virtual Machines Hypervisor

  9. Virtual Machines on Host OS

  10. Examples of VM • Oracle VM VirtualBox • VMWare Player • QEMU (Quick EMUlator)

  11. How to Build Drivers

  12. Commands to Download Tools • On Ubuntu12.04 • sudo apt-get update • sudo apt-get install make • sudo apt-get install build-essential • sudo apt-get install vim • sudo apt-get install linux-headers-$(uname -r)

  13. Makefile obj-m = hello.o KVERSION = $(shell uname -r) all: make -C /lib/modules/$(KVERSION)/build M=$(PWD) modules clean: make -C /lib/modules/$(KVERSION)/build M=$(PWD) clean

  14. hello.c #include <linux/init.h> #include <linux/module.h> #include <linux/sched.h> MODULE_LICENSE("Dual BSD/GPL"); static int hello_init(void) { return 0; } static void hello_exit(void) { printk(KERN_ALERT "Goodbye, cruel world\n"); } module_init(hello_init); module_exit(hello_exit);

  15. Compile and Use It • make • sudo insmod hello.ko • sudo modprobe hello.ko try to also load other modules for undefined symbols • sudo rmmod hello • dmesg

  16. Requirements • Install a virtual machine on your computer • Install Linux and Windows 7 (or Windows XP) on the virtual machine • Implement a device driver • Print “Hi, I am Student-ID” to the kernel buffer when inserting the module • Print “Bye!” to the kernel buffer when removing the module • Hint: you can use the command dmesg to read the buffer

  17. Report • The steps for your implementation • The problem you met and how you solved it • The bonus you have done • The reference of this project • The report is limited within 4 pages

  18. Grading • Implementation • The VM: 20% • The OS: 20% (10% for each) • The driver: 20% • Report • 40% (the baseline is 30%) • Bonus • Recompile the Linux kernel on the VM: 10% • Implement a system call on the Linux kernel: 10%

  19. Submission • Project deadline: at 15:00 on 2014/01/17 NO DELAY! • Send your report and the compiled device driver (module) to TA:蔡宗佑 fatguy2991@gmail.com • The title of the email: OS Project of Student-ID • The title of the report: OS_Name_Student-ID • The title of the driver: Driver_Student-ID.ko • Point deduction for wrong format: 10% DEMO might be requested
