All,
I'm trying to find an entry point of hard disk I/O in PTLSIM source tree.
Even though I haven't looked at the entire source codes fully, I found that
the following parts are visited when I do a file I/O.
(in $MARSS/ptlsim/core/ooocore.cpp)
....
case COMMIT_RESULT_EXCEPTION: {
if (logable(3) && thread->current_basic_block &&
thread->current_basic_block->rip) {
ptl_logfile << " [vcpu ", thread->ctx.cpu_index, "] in exception
handling at rip ", thread->current_basic_block->rip, endl, flush;
}
exiting = !thread->handle_exception();
break;
}
....
Then, my question is whether all accesses to hard disk go through the above
code segments.
If not, can any one explain about the entry points for hooking hard disk
accesses?
Thanks.
