Function Documentation

panic_stack_trace()

void panic_stack_trace

(

const interrupt_frame_t *

frame

)

Print a stack trace from a interrupt frame.

Will NOT panic the kernel, just print the stack trace.

Parameters

frame

Pointer to the interrupt frame.

Definition at line 261 of file panic.c.

Here is the caller graph for this function:

panic()

NORETURN void panic	(	const interrupt_frame_t *	frame,
		const char *	format,
			...
	)

Panic the kernel, printing a message and halting.

If QEMU_EXIT_ON_PANIC is defined and we are running in QEMU, will exit QEMU instead of halting.

Parameters

frame	Pointer to the interrupt frame, can be NULL.
format	The format string for the panic message.
...	Additional arguments for the format string.
