I thought HarmonyOS used the Linux kernel for larger devices, and LiteOS was more for smaller IoT, wearables, etc?

- cbsmith 3y agoThey call it "multikernel", but it's really more the standard "microkernel hosting kernels" model. On small devices, they don't include the Linux support, but it supports a Linux Kernel Abstraction Layer that in turn hosts a modified ASOP. You can find similar examples of this all across the real-time OS space. Other examples include QNX and the NT Kernel, which traditionally hosted the Windows "personality".
