Dear gem5 team, I am trying to understand and modify gem5 memory system. However, I am not familiar with swig and confused about gem5 memory system.
First, does the fs.py of X86 linux system use *PhysicalMemory* as wrapper of *TestMemClass*? When I try to find how gem5 allocate memory for simulated system, I only find *mmap()* function in *PhysicalMemory::createBackingStore*. As far as I see, all memory will be inited in *createBackingStore?* Second, the *memories* of *test_sys* in fs.py contain: *physmem* and *memories. *As I understand, *memories **, *instead of *physmem,* is used for *physmem *variable in *sim/system.cc**. *In fs.py, how is *physmem *used if there is no corresponding code in c++ to *physmem*? Third, if I want to add two memory controller to *test_sys*, should I change the code *self.physmem = MemClass(range = AddrRange(mdesc.mem()))* to *self.physmem = PhysicalMemory(self.name <http://self.name>, self.memories)* ? Thank you for your reply first~ -- Best regards！ ------------------------------------------------------------------- Wayne Zhang Department of Computer Science, HKU E-mail:[email protected] <[email protected]> _______________________________________________ gem5-dev mailing list [email protected] http://m5sim.org/mailman/listinfo/gem5-dev
