A question about paging

Post by sevobal »

Hey everyone,
I've a little question about Paging. After booting my kernel the physical adresses 0-10 MB are direct mapped to the virtual adresses 0-10 MB. So far there is no problem. If a program now tries to access an address above the 10 MB limit the CPU fires up a page fault exception and my kernel has to handle it. Now I should map the required address for the program, but how can I dected which address was requested by the program. I could guess the CPU is telling me the address when the exception fires up, but where?
I hope you can help me a little.

Greetings
