Assignment #$2-$ Keyboard Hit and Process Message Counter

Part a$)$ Modifiy the Minix $2\mathrm{.}0\mathrm{.}4$ kernel so that when a user press F$9$ key kernel prints a

Hello World message. Do not use any other function key!

Hint: Possible files you need to update are dmp$.$c$,$ dmp$\_$kernel.c and proto.h

Part b$)$ Minix uses message passing paradigm to send and receive information among the

processes for IPC purposes. Add code to the MINIX kernel to keep track of the number of messages

sent from process $i$ to process $j.$ Print this matrix in a user$-$friendly format when the F$9$ key is hit.

You need to find the proper C files for implementing the code.

Hints: $/$usr$/$src$/$kernel

proc.c$,$ glo.h$,$ table.c$,$ and other files from part a
