[gem5-users] booting dual operating systems in Gem5

[Thawra Kadeed]

Hello everyone,

I was looking for the possibility of booting dual operating systems
(e.g. Linux and real-time OS) in Gem5. I have not seen any
documentation/support to that.

Is anyone aware of Gem5 capabilities to support such a case?


Thanks in advance.
Best regards,
Thawra

Hi, I don't know the answer, but you likely have to explain the following:

How would the OSes communicate? Two separate systems over a network?
Or will the share the same memory? If share memory, do you want 2 OS
via hypervisor or something else?

Hello Ciro,

thanks a lot for your reply.

The OSes are supposed to use a shared memory to communicate with each
other. Moreover, in the platform, we use a network on chip to connect
cores with each other, not a normal bus.

So do you have an idea about Gem5 support to run the OSes under these
circumstances?

Thanks in advance.
