* Name: sim_smp_hook
|
|
*
|
|
* Description:
|
|
* This is a mindless little hook between sim_idle_trampoline() and the
|
|
* real IDLE task logic. This is only needed because we need to access
|
|
* elements of the TCB in the simulation domain but sim_idle_trampoline()
|
|
* lies in the host domain.
|
|
*
|
|
* Input Parameters:
|
|
* None
|
|
*
|
|
* Returned Value:
|
|
* None (should not return)
|
|
*
