# UVMTd

System Daemons for stress-testing UVM on OpenBSD. 

## Description

The intention for this project is to provide easy to run

daemons to test the behavior of the UVM system over time 

to catch bugs. There will be daemons both for black-box 

testing(i.e., holding large amounts of memory for varying

times and validating constantly), and for white-box testing

(i.e., using knowledge of UVM to force certain permutations

of the underlying vm_map structure).

## How to build

This project is intended to be run on OpenBSD, with

no other dependencies.

1. `git clone` this directory

2. run `make` in the cloned directory

3. run `./UVMTd` to spawn the two available daemons

## How to use 

At the moment, there is no UI to the program. All

files containing daemons are prefixed with `daemon_`.

The function needed to create them is found in

`spawn.c`. To display all running UVMTd daemons and information

about them, use the `dispd.sh` script, and to kill all daemons,

use the `killd.sh` script.
