Hi!
I'm trying to create a MyMemory class that is a subclass of the
SimpleMemory class in order to have a new kind of memory with additional
features. Unfortunately, I'm having some troubles, I hope someone can
help me. This is basically what I've done:
1) I've added a my_mem.hh in src/mem that declares the class as
follows:
#include "mem/simple_mem.hh"
class MyMemory : public SimpleMemory
{
public:
MyMemory(const MyMemoryParams *p);
virtual ~MyMemory() {}
int extension;
}
2) I've added the corresponding my_mem.cc in src/mem that contains the
following:
#include "mem/my_mem.hh"
MyMemory::MyMemory(cont MyMemoryParams *p) : SimpleMemory(p) {
extension = 1; }
MyMemory* MyMemoryParams::create() { return new MyMemory(this); }
3) I've added a MyMemory.py in src/mem that contains the following:
from m5.params import *
from SimpleMemory import *
class MyMemory(SimpleMemory):
type = 'MyMemory'
cxx_header = "mem/my_mem.hh"
port = SlavePort("Slave ports")
latency = Param.Latency('30ns', "Request to response latency")
latency_var = Param.Latency('0ns', "Request to response latency
variance")
bandwidth = Param.MemoryBandwidth('12.8GB/s',"Combined read and
write bandwidth")
4) I've added the following lines in src/mem/SConscript:
SimObject('MyMemory.py')
Source('my_mem.cc')
5) I've tried to use it modifying the configs/examples/se.py, changing
the following:
- physmem = SimpleMemory(range=AddrRange("512MB"))
+ physmem = MyMemory(range=AddrRange("512MB"))
The problem I'm having is that, when I compile, I get an error saying
that MyMemoryParams does not exist:
build/X86/mem/my_mem.hh:66:23: error: 'MyMemoryParams' does not name
a type.
Can anybody help me on trying to figure out what is happening? I'm
basically trying to mimic the way the SimpleMemory class is declared to
declare the MyMemory class, am I doing something wrong? I've been unable
to find anything related to the declaration of the SimpleMemoryParams, I
guess it's the python system that generates it by itself, but fore some
reason it's not doing it for the MyMemoryParams...
Any kind help is appreciated.
Thanks in advance,
Lluc
