What's the relationship between F9 microkernel and BitSec #149

BaikalHu commented 7 years ago

I'm learning f9-kernel on STM32F429I board, and read . F9 and BitSec are the 3th generation microkernel, and BitSec is learnt from uVisor, focus on security. As I read the f9-kernel source code, f9-kernel use MPU in Cortex-M3/4 to do it. I think BitSec also base on MPU. So what's the relationship between f9 and BitSec? what's the differences between them? what's the BitSec's advantage?

From the perspective of microkernel design, F9 microkernel belongs to second generation so does L4Ka. BitSec was constructed with capability model, which is a major feature in 3rd generation microkernel. The source code of BitSec hypervisor is not yet publicly available though.
