Hi,
I am trying to map local APIC on an intel system (physical address 0xfee00000) in a user level program using mmap but my mmap is failing saying "Bad file descriptor". I am not sure if this problem is related to apic or mmap. I am running the program as root. Please help me figure this out.
could you post the code? anyway, check "man mmap" in "errors" section....the hint could be found there..... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
