so far, i have figured out the problem with the interrupt problem, but i cannot seem to acknowledge the interrupt after i have received it. The problem apparently is that the MR0 doesn't seem to completely clear the 32nd bit always seem to be set. my code looks like this:
L4_LoadMR(0, 0); L4_Send(root); //so i can actually see what value is sent out in the ipc
since we know there is no type or untyped words i simply check the label and i obtain this number :
decimal: 32768 binary: 1000000000000000
why is this so and how do i completely zero MR0?
