Hi - I can't seem to find any information on how to get m5 to load and
run an eio trace in SE mode? Can anyone help me with this?
I have it working (partial script below), but there may be problems
with using EIO files in m5. For some programs I found that the
instruction numbers were getting out of synch. This isn't a problem
if you comment out the following code in eio.cc (at line 444):
if (icnt != (Counter) exo_icnt->as_integer.val) {
ccprintf(cerr, "actual=%d, eio=%d\n", icnt,
(Counter) exo_icnt->as_integer.val);
fatal("%s: EIO trace inconsistency: ICNT mismatch", name());
}
As long as the subsequent checks work out, there is no problem.
Unfortunately, I have a small number of checkpoints for which there is
a register-mismatch. I need to investigate.
Plug this into se.py, replacing the existing options:
parser.add_option("-e", "--eio", default="",
help="The eio trace to run in syscall emulation mode.")
parser.add_option("-c", "--chkpt", default="",
help="The checkpoint to load.")
process = EioProcess(file = options.eio)
if options.chkpt != "":
process.chkpt = options.chkpt
if options.detailed:
#check for SMT workload
eios = options.eio.split(';')
if len(eios) > 1:
process = []
smt_idx = 0
chkpts = []
if options.chkpt != "":
chkpts = options.chkpt.split(';')
for eio in eios:
smt_process = EioProcess()
smt_process.file = eio
if chkpts and chkpts[smt_idx]:
smt_process.chkpt = chkpts[smt_idx]
process += [smt_process, ]
smt_idx += 1
