  • rtems/score/cpu.h, rtems/score/types.h: Refactoring of priority handling, to isolate the bitmap implementation of priorities in the supercore so that priority management is a little more modular. This change is in anticipation of scheduler implementations that can select how they manage tracking priority levels / finding the highest priority ready task. Note that most of the changes here are simple renaming, to clarify the use of the bitmap-based priority management.

100        * cpu.c, cpu_asm.S, rtems/score/cpu.h: Context switch now works well
101        enough to run ticker to completion with the simulator clock idle
102        task. But if you comment out the printk's in _CPU_Context_Initialize,
103        it hangs. This remains to be investigated.

201        parameter to indicate that the port uses the Simple Vectored
202        Interrupt model or the Programmable Interrupt Controller Model. The
203        PIC model is implemented primarily in the BSP and it is responsible
204        for all memory allocation.
