FIASCO_FASTCALL int thread_handle_trap (  Trap_state *  ts  )

The catch-all trap entry point. Called by assembly code when a CPU trap (that's not specially handled, such as system calls) occurs. Just forwards the call to Thread::handle_slow_trap(). Parameters: state  trap state Returns: 0 if trap has been consumed by handler; -1 if trap could not be handled.

FIASCO_FASTCALL int thread_page_fault (  Address  pfa, Mword  error_code, Address  ip, Mword  flags, Return_frame *  regs )

The low-level page fault handler called from entry.S. We're invoked with interrupts turned off. Apart from turning on interrupts in almost all cases (except for kernel page faults in TCB area), just forwards the call to Thread::handle_page_fault(). Parameters: pfa  page-fault virtual address error_code  CPU error code Returns: true if page fault could be resolved, false otherwise

FIASCO_FASTCALL void thread_timer_interrupt (  Address  ip  )

void thread_timer_interrupt_slow (  void   )

Slow version of timer interrupt. Activated on every clock tick. Checks if something related to debugging is to do. After returning from this function, the real timer interrupt handler is called.

void thread_timer_interrupt_stop (  void   )

Extra version of timer interrupt handler which is used when the jdb is active to prevent busy waiting.
