Doorbell Interrupt Base Support for Core/Thread Wakeup
This change includes:
- Implementation of a generic KernelWorkItem Class
- Kernel functionality for doorbell send to specific PIRs
- Kernel changes to send core/thread Wakeup doorbells using
doorbell_send() + placing KernelWorkItems on a cpu stack obj
to be executed during doorbell wakeup
- Kernel Interrupt Message handler changes to send wakeup msgs
- Interrupt Resource Provider (INTRRP) Changes to handle
wakeup msgs and monitor for timeouts
- Changes to the IPL flow to invoke proper Core/Thread Wakeup
- A basic outline (commented out) for how IPC messages can be
implemented in the future
