pintos-env

pintos-env provides pintos build/test environment with docker image, including QEMU 2.5.0, GCC 7.5.0, Ubuntu 16.04, for students who want or need to run pintos on their local machine. Building and testing pintos on local machine will save you from repeated uploading source code and long compile/run time.

This docker image is based on Ubuntu 16.04 Xenial, includes QEMU 2.5.0 and GCC 7.5.0, which are minimal requirement for pintos to run.

Requirement

All you need is Docker. That's what this project is for. Once you uninstall Docker, nothing will left on your machine.

Usage

For macOS/Linux

  1. Open Terminal.app
  2. Go to your pintos project directory that directly includes threads directory.
  3. ./run.sh
  4. Now you have linux shell with pintos build/debug dependencies.

For Windows

  1. Open terminal such as PowerShell or git bash
  2. Go to your pintos project directory that directly includes threads directory.
  3. docker run -it --rm -v "$(cd)":/root/pintos lego3410/pintos
  4. Now you have linux shell with pintos build/debug dependencies.

Note: Not tested enough on windows. Please create issue if there is any trouble.

No Guarantee

Even though this image imitates most of actual build environment, tests may pass but it does not guarantee that it will be on server. Before final submission, be sure to test it on server more than once.

Issue Reporting

Whenever any relevant trouble occurs, or any improvement idea comes into your mind, feel free to report issue.

Simple irrelevant Tip

You may use -j option within make to enable parallel compiling.

Use make -j, or make -j8 for 8 parallel compiler threads. You can get more than 4X faster compile time.

$ time make
...
real  0m43.633s
user  0m5.072s
sys   0m5.580s
$ time make -j
...
real  0m10.401s
user  0m8.927s
sys   0m12.912s

Project 3 VM Build, Tested on Mac Pro 2013, 3.5 GHz 6-Core "Ivy Bridge-EP" Intel Xeon (E5-1650 v2) with 12 MB L3 cache, 16 GB DDR3 ECC at 1866 MHz

Same option can be applied to make check. However, running too many qemus may harm performance and cause memory shortage, therefore use -j6~-j12 is appropriate.

Future improvements

  1. Alpine linux image less than 100MB
  2. Bochs
  3. GCC 7.4.0. There is no reported trouble with GCC 7.5.0 yet, but standard compiler is GCC 7.4.0.
