It looks like there are two (or more) problems here:
1. Something wrong with MIPS (we'll look into this ASAP, probably on Monday)
2. ARM FS + Ruby
I'd like to discuss the latter for a moment.
Here's the backtrace:
Traceback (most recent call last):

AttributeError: object 'RubySequencer' has no attribute 'cpu_side_ports'
(C++ object is not yet constructed, so wrapped C++ methods are
unavailable.)
The problem here is that we made an assumption in "base_config.py" that the
interface to a Ruby sequencer and a xbar is the same. I don't think this
makes sense. The xbar has CPU-side and memory-side ports. A Ruby sequencer
should only have an incoming port. (Currently, after the terminology
change, the name is "response_ports" which is probably not the right name.)
So, I have a couple of questions:
1. What is the "right" names for the ports on the sequencer? Right now, we
have 5!! ports on each sequencer. This doesn't seem necessary.
response_ports = VectorResponsePort("CPU response port") (was "slave")
request_ports = VectorRequestPort("CPU request port") (was "master")
pio_request_port = RequestPort("Ruby pio request port") (was
"pio_master_port")
mem_request_port = RequestPort("Ruby mem request port") (was
"mem_master_port")
pio_response_port = ResponsePort("Ruby pio response port") (was
"pio_slave_port")
To be honest, I would consider myself a ruby expert, but both the old names
and the new names are inscrutable to me. If anyone has any suggestions, I'm
happy to hear them.
2. Do we really want the Ruby sequencer to have the same interface as the
XBar? If so, we should create a base class so they can both implement that
interface. The current code in BaseCPU.py has used python's duck-typing too
heavily, and this is really biting us right now.
If anyone has ideas on how to improve the "connectPort" interface on the
CPU, please let me know. I think that it's probably better to do this *in
the cache model* as the CPU is the one with the consistent interface
(icache_port and dcache_port are defined in BaseCPU.py). I'm open to
suggestions.
Finally, I'll try to find the time myself to look into the problem with
Ruby, but I can't promise anything will be done quickly. I imagine the long
test failures are going to bug us until at least early next week.
Cheers,
Jason
