-# Opgaver til operativ systemer
-
-Ligenu er det ikke delt op i mapper. 
-
-## Kør mini kernel modul
-
-Compile med make.
-Husk at peg makefile på din kernel modul mappe.
-Denne er testet på ubuntu server 19.04.
-
-```
-make
-```
-
-Nu burde der være kommet et jmod.ko som kan loades med.
-
-```
-sudo insmod jmod.ko
-```
-
-Hvis du får permission denied kan du få flere information ved at checke `dmesg` loggen.
-
-Nu kan du hente major number ind fra dmesg. Led efter `COOL_MODULE:`.
-Dette nummer bruger du til at assign den en node
-
-```
-sudo mknod /dev/cooldev c MAJOR 0
-```
-
-Dette vil map kernel-modul/driver til cooldev i /dev/ mappen.
-Husk at skriv til MAJOR nummer fra `dmesg` i stedet for MAJOR.
-
-Hvis man læser man pagen kan man se at det bliver lavet som en character unbuffered file. 
-MINOR nummeret er 0 da vores driver alligevel ikke bruger det til noget.
