Ok, de acord, observ asta din debugging. Dar, desi protectia e buna, da in
continuare SIGSEGV de acces:
[sig_handler(), vmsim.c:104] Page 1
with fault code 2 vs SEGV_ACCERR=2
when protection is 0 vs PROT_READ=1
[lru_in_ram(), vmsim.c:73] Mapping page 1 with prot 1 vs PROT_READ=1
[lru_in_ram(), vmsim.c:84] Page 1 mapped to frame 0
[sig_handler(), vmsim.c:104] Page 1
with fault code 2 vs SEGV_ACCERR=2
when protection is 1 vs PROT_READ=1
[sig_handler(), vmsim.c:104] Page 1
with fault code 2 vs SEGV_ACCERR=2
when protection is 2 vs PROT_READ=1
Adica, desi pagina e mapata in RAM cu protectia PROT_READ (testul 21 e cel care
se agata), primesc in continuare fault de acces si fiind in RAM, inca un fault
de acces inseamna mprotect(PROT_WRITE); de aici incolo ramane intr-o bucla
infinita. De ce?
Multumesc, Andreea
