Brief outline

(From the slides)

Welcome to the discipline Operating System II

Objective: To exercise the concepts studies in Operating Systems I (theoretical).

• to understand how theory applies in practice
• to gain familiarity with the implementation of OSs
• to know the state of the art in related technology

Approach

• Hands-on approach
• Work with real-world situations

Plan

• Basic conceptual background (refresh)
• Development enviroment (the real thing)
• Warm-up
• development of a shell for linux (get used to syscalls)
• linux kernel hacking, make new syscall (see examples)

• Main project: make an OS from the scratch (for i366 PC arch.)

Material

• Computer language: C
• Platform: gnu/linux
• Tools: gcc, libc, make, svn, qmu (emulator), PC hardware

Bibliograpny

• GNU website: www.gnu.org (manuals)
• OSDEV: wiki.osdev.org
• Intel Architecture Software Development, System Programming
• kernel newbies: kernelnewbies.org
• Google: www;google.com

• best place to learn: /usr/src

Program

• Tools: 1 class
• Shell project: 2 classes (deliverable 2 weeks later)
• Linux hacking: 2 classes (deliverable 2 weeks later)
• SO Project: the rest of the semester (deliverable, in the workshop)

Workshop

• By the end of the semester we will make an workshop
• Every team will present its OS project
• We will have an evaluation board composed by experts from the industry
• Other students can attend to the workshop

Evaluation

• The final score will be computed from the projects evaluation
• We will have a final examination for validation
• Who scores at least 5.0 in the test, will have the project scores
• Who doesn't score at least 5.0, will have the test score
• The idea is
• if you really work in the projects, the test will be a piece of cake
• if you "hitchhike" on the others' work... kkkkkk... sorry... ;-)

How to calculate the final score

#include <stdio.h>
#include <stdlib.h>
int main (void)
{
  float nota_shell, nota_so, nota_prova;      /* entre 0 e 10 */
  float nota_linux;                           /* entre 0 e 1  */
  float media_final;                          /* entre 0 e 10 */
  scanf (“%f %f %f”, &nota_shell, &nota_linux, &nota_so);
  if ( (nota_prova >=5))                                           /* Normal */
     media_final = nota_so*0.6 + nota_shell*0.3 + nota_linux + nota_prova/10;
  else                                                             /* Chii...*/
     media_final = nota_prova;
  if ( (nota_final >=2) && (nota_final <3) && (nota_linux >= 0.5)) /* Canja */
     nota_final = 3
  return  nota_final >=3 ? EXIT_SUCCESS : EXIT_FAILURE;
}                                          /* cat choramingos > /dev/null*/

Tip: if you can't understand the code above, get a good C-book and learn asap!
