Microkernel-based Operating Systems - Exercise 3, WS2018
--------------------------------------------------------

Download L4Re tarball from 1st exercise:
https://os.inf.tu-dresden.de/Studium/KMB/WS2018/Exercise1.tar.bz2

Unpack and build it:
#> cd /where/you/want
#> tar xvf /where/you/put/Exercise1.tar.bz2
#> cd tudos
#> make setup
  ---> choose x86-32
#> make -j8

Download exercise template:
https://os.inf.tu-dresden.de/Studium/KMB/WS2018/Exercise3.tar.bz2

Unpack exercise tarball _next to_ tudos directory:
#> cd ..
#> ls
tudos
#> tar xvf /where/you/put/Exercise3.tar.bz2
#> ls
tudos
ex3
^^^^^ --- tudos and ex3 in same directory

Now build 'faulty' and the (still empty) 'executor' programs:
#> make -C ex3/src

Add a new entry to tudos/src/l4/conf/modules.list:

entry faulty
roottask moe --init=rom/faulty
module l4re
module faulty

Run faulty in QEmu:
#> make -C tudos/obj/l4/x86 qemu E=faulty

You should see an output line saying 'Hello, I am faulty.'.

Modify modules.list so that 'executor' is started instead, with 'faulty' being
passed as an additional module:

entry faulty
roottask moe --init=rom/executor
module l4re
module executor
module faulty

Extend ex3/src/executor/executor.cc into a program loader and pager for
'faulty'. The goal is to run the 'faulty' program in a new task and handle all
page faults until the program successfully prints 'Hello, I am faulty.' again.
