| Description | Given an emerging trend towards OS-capable heterogeneous-ISA multi-core processors, we address the problem of how to redesign classic symmetric multi-processing (SMP) oper-ating systems (OS) to exploit this hardware. We propose an OS design that consists of multiple kernels, each one compiled for, and run on, a specific ISA of the heteroge-neous platform. These kernels collaboratively maintain a distributed OS state, share hardware resources and transfer their workload. Following these design principles, we iden-tify a set of features that should be implemented in SMP OSs to realize our OS design. We deploy these features in Linux to produce a homoge-neous prototype of our OS design. We evaluate this proto-type by partitioning a multi-processor machine to run multi-ple kernels. We compare against traditional Linux to demon-strate that our redesign does not hinder performance. |
