Asymmetric multi processing in layerscape LS1088

nithindas — Mon, 20 Jul 2020 18:26:17 GMT

I am trying to figure out a way that I can run two independent Linux operating systems on the Layerscape LS1088A processor without using a hypervisor( Type 1). I see a whitepaper discussion of the same which is tried out in Intel (Twin-Linux). Is it possible to do the same in Layerscape LS1088?

Setting up all resource assignment, isolation and protection modules on
Layerscape SoCs would result in an OS-level complexity code. On the other
hand, leaving these SoC resources intact and relying purely on the collaborative
multiprocessing model is not feasible due to lack of protection against
programming errors. For the reasons mentioned above, no ready recommendations
are available for running multiple OS'es on LS processors without a hypervisor.
Our recommendation in this regard is, use virtualization. LSDK-supported
virtualization techniques are described in the online documentation.

Thank you for your reply. Yes I am currently using the kvm qemu and part of the issue is that it is a kernel hosted hypervisor. I tried to get a type 1 hypervisor and unfortunately the costs are very exorbitantly high. I thought it would be good if we have a way to run independent linux OS on different cores.
