Function Documentation

void kinit (  void *  arg  )

Kernel initialization thread. kinit takes care of higher level kernel initialization (i.e. thread creation, userspace initialization etc.). Parameters: arg  Not used. Definition at line 84 of file kinit.c. References config, thread::cpu, config_t::cpu_count, cpu_list(), cpus, thread::flags, interrupts_disable(), kcpulb(), kmp(), NULL, panic, spinlock_lock, spinlock_unlock(), TASK, THREAD, thread_create(), thread_detach(), thread_join, thread_ready(), and X_WIRED. Referenced by main_bsp_separated_stack(). Here is the call graph for this function:

void main_ap (  void   )

Main kernel routine for application CPUs. Executed by application processors, temporary stack is at ctx.sp which was set during BP boot. This function passes control directly to main_ap_separated_stack(). Assuming interrupts_disable()'d. Definition at line 268 of file main.c.

Here is the call graph for this function:

void main_ap_separated_stack (  void   )  [static]

Main kernel routine for application CPUs using new stack. Second part of main_ap(). Definition at line 314 of file main.c. References ap_completion_wq, scheduler(), timeout_init(), waitq_wakeup(), and WAKEUP_FIRST. Referenced by main_ap(). Here is the call graph for this function:

void main_bsp (  void   )

Main kernel routine for bootstrap CPU. Initializes the kernel by bootstrap CPU. This function passes control directly to main_bsp_separated_stack(). Assuming interrupts_disable().
