Hi Andrea,
Thank you for your reply!
I added the Object to SimObject but the system run with fatal:
gem5-dev/configs/common/CacheConfig.py:48: SyntaxWarning: import * only allowed
at module level
def config_cache(options, system):
Global frequency set at 1000000000000 ticks per second
info: kernel located at: /opt/M5_system_ALPHA_small/binaries/vmlinux
Listening for system connection on port 3456
fatal: system.ruby.l2_cntrl5.myclass without default or user set value
I wanna add an machine to L2 level. The src modification with protocol change
has been
done without compiling error.
For python script I added such file
src/mem/ruby/system/myclass.py:
from m5.params import *
from m5.SimObject import SimObject
class myclass(SimObject):
type = 'myclass'
cxx_class = 'myclass'
cxx_header = "mem/ruby/system/myclass.hh"
param1 = Param.Int(20, "param1 default value 20");
Also with modified of configs/ruby/MESI_Two_Level.py since this is the protocol
I am using now:
I add:
class myclass(myclass):
param1 = 20
in the L2 part:
for i in xrange(options.num_l2caches):
...
#
# First create the Ruby objects associated with this cpu
#
l2_cache = L2Cache(size = options.l2_size,
assoc = options.l2_assoc,
start_index_bit = l2_index_start)
l2_cntrl = L2Cache_Controller(version = i,
L2cache = l2_cache,
transitions_per_cycle=options.ports,
ruby_system = ruby_system)
myclass_cntrl = myclass() #try to initiate param1
exec("ruby_system.l2_cntrl%d = l2_cntrl" % i)
...(rest of the code)
I get confused and I don't know how to pass value to param1 from python script
to Ruby now.

Hi Wei,
Is your object a subclass of SimObject? If not, regStats will never be
called (or you have to get the parent/owning object to call it explicitly).
