[gem5-users] uncacheable addresses

[Lorenzo Zuolo]

Hi everybody,

I have a very stupid question.
I'm new in gem5 and I would like to understand how to make an address
region uncacheable with ARM architecture in se mode.
Problem is. I would like to have the possibility to access an address
outside the dram range from a c program I'm executing in SE mode.
Example is:
Dram range is [0x0-0xFFFF]
Desired address region is: [0x10000-0xFFFFF]

In the c program I'm running on the core I would like to be able to do
something like this:

int main {
    char *reg=(char*)0x10000 //pointer to non cacheable memory region

    printf("value is %d\n",*reg);
}

Any thought on that?

Thanks in advance
