The error is for the sumulated memory size. There is a new memory model
for version 2 of the simulator in which the size of physical memory in
syscall emulation must now be specified. The error comes becasuse the
size of the physical memory in the machine you are simulating is not large
enough. The default size is 128 MB if the parameter for the address range
isn't specified. You can increase the size by changing the parameter in
the configuration when the physical memory is instantiated. For example
to create a physical memory with 512MB you would do it as follows:
PhysicalMemory(range=AddrRange("512MB"))
Hope that helps,

I used EioProcess to read EIO traces under M51.1, it was great.
Currently I am migrating my code to M52.0b2(plus M5 2.0b2 encumbered

, however I met error below:

============================================================
When eio file is large( > 400MB) I met the problem, If the eio file is
small(<100MB), it is OK.
The machine I use has 8GB memory and since I can run m51.1 with eio traces,
I think it is not a machine problem.
Can any of you help me out? I am not sure if I config something wrong.
Thanks,
Jiang
