). The thin kernel intercepts interrupts to ensure that the non-real-time kernel cannot preempt the operation of the thin kernel. This allows the thin kernel to provide hard real-time support. Although the thin kernel approach has its advantages (hard real-time support coexists with the standard Linux kernel), there are drawbacks to this approach. Real-time and non-real-time tasks are independent, which makes debugging difficult. Also, non-real-time t

If it is not a multiple of 4, the last few KB will not be available. There's nothing special about swapping partitions. The only difference is that it is used as the original partition, that is, there is no file system, it is best to mark
