Pintos

Pintos is a simple operating system framework for the 80x86 architecture. This is our semester project for CS 333 at Alexandria University. We are assigned certain tasks to improve the implementation of Pintos.

Quickstart

Install Bochs

Download the source code of Bochs 2.2.6 or Bochs 2.6.2

Use either of the two build scripts src/misc/bochs-2.2.6-build.sh and src/misc/bochs-2.6.2-build.sh depending on your downloaded version of Bochs to patch, build, and install it

usage: env SRCDIR=<srcdir> PINTOSDIR=<srcdir> DSTDIR=<dstdir> sh src/misc/bochs-2.6.2-build.sh
  where <srcdir> contains bochs-2.6.2.tar.gz
    and <pintosdir> is the root of the pintos source tree
    and <dstdir> is the installation prefix (e.g. /usr/local)

Run Pintos

Setup the environment variables by sourcing SETUP_ENV.sh from the root of the repository:
```
$ source SETUP_ENV.sh
Updating PATH...
Updating GDBMACROS...
```
Build the source code of the project you are working on (e.g.: threads, userprog, vm, filesys):
```
src/threads $ make
```

Run Pintos in a simulator using pintos, for example:

src/threads $ pintos -h

Output:
