[gem5-users] Problem with I/O mapping in SE mode

[Lorenzo Zuolo]

Hi,

I'm trying to instantiate a fake_isa in my gem5 platform. The idea is to
understand how its works and than modify the device to fit my requirements.
>From my understanding it is necessary to first instantiate the module on
the main python script like this:

system.IsaFake = IsaFake()
system.IsaFake.pio_addr="0xAAAA0000"
system.IsaFake.pio_size= '100'
system.IsaFake.pio = system.membus.master

then, to avoid to get blocked by the mmu it is necessary to map the
addresses of the I/O device I've connected to the bus like this:

binary = '/home/lore/configure/bin/configure'
process = LiveProcess()
process.cmd = [binary]
system.cpu.workload = process
system.cpu.createThreads()
root = Root(full_system = False, system = system)
m5.instantiate()


*root.system.cpu.workload.map(0xAAAA0000,0xAAAA0000,256)*
however when I try to execute the script this error is shown:




*root.system.cpu.workload.map(0xAAAA0000,0xAAAA0000,256)AttributeError:
'SimObjectVector' object has no attribute 'map'*
Where am I wrong?

Thanks

Lorenzo
