[gem5-users] fatal: Number of ISAs (0) assigned to the CPU does not equal number of threads (1)

[Jimmy Situ]

Hi, All


I try to run FS mode with gem5, but I get an fatal like this
fatal: Number of ISAs (0) assigned to the CPU does not equal number of threads (1)


An answer of this issue from google search is to call createThreads() method. I try this call but it doesn't work for my case


My configure file (run.py and system.py) is here
https://github.com/jimmysitu/gem5-bench/blob/master/configs/run.py
https://github.com/jimmysitu/gem5-bench/blob/master/configs/system.py


I almost follow the ones on powerjg/gem5
https://github.com/powerjg/gem5/tree/features/simplefs/configs/myconfigs


Do I miss anything else?
Thanks.

Hi, All


I think I found the root cause of this issue, I define a timing cpu model in the createCPU(), and missing the createThreads() call
My code is below:
def createCPU(self):
self.cpu = [AtomicSimpleCPU(cpu_id = i, switched_out = False)
for i in range(self._opts.cpus)]
self.mem_mode = 'atomic'
for cpu in self.cpu:
cpu.createThreads()



self.timingCpu = [DerivO3CPU(cpu_id = i, switched_out = True)
for i in range(self._opts.cpus)]
for cpu in self.timingCpu:
cpu.createThreads()


I still not quite under the usage of createThreads(), can any one help explain this?
Thanks.

Hi Jimmy,

Oops. I thought I sent this yesterday... sorry :). It looks like you
figured it out in the meantime.

That branch is a little old. You also need to call createThreads() on the
timingCpus. See
https://github.com/darchr/gem5/blob/feature/simplefs/configs/myconfigs/system/system.py#L140

createThreads() does some boilerplate setting up of the threads for the
CPUs, like setting the ISA. This could be done in the runscripts, but it
would be code that was duplicated in each instance. I think this could have
a better API, and I wish I had time to work on it!

Cheers,
Jason

Hi, Joson


Thanks for your explanation and help.
I am now run into another cache hierarchy problem with gem5. I may raise a mail with different title talk about it.


Thanks.
