Hello,
I am trying to setup an asymmetric multiprocessor using two different types
of Alpha cores, one O3 and the other TimingSimple. I modified the fs.py
configure script by simply appending one more core to the cpu list of the
test_sys as follows:
test_sys.cpu = [TestCPUClass(cpu_id=i) for i in xrange(np - 1)]
test_sys.cpu.append(DerivO3CPU(cpu_id=np - 1))
This doesn't work however and gives me the following error:
command line: ./build/ALPHA_FS/m5.opt configs/myconfigs/fs.py -n 3 --caches
-t
Global frequency set at 1000000000000 ticks per second
Error in unproxying param 'system' of (orphan)
Traceback (most recent call last):

(self.path(), self._pdesc.ptype_str, base.path())
AttributeError: Can't resolve proxy 'any' of type 'System' from '(orphan)'
When I do it this way it works fine and boots the kernel:
test_sys.cpu = [TestCPUClass(cpu_id=0), TestCPUClass(cpu_id=1),
DerivO3CPU(cpu_id=2)]
The problem is I want this to be configurable. Is there a way to do this
without hard coding the cpu list? Or should I take a different approach
altogether?
-Tony
