panic.h

Crash handling header.

Define a panic.h::core_panic() function that allows to stop/reboot the system when an unrecoverable problem has occurred.

enum core_panic_t

PANIC_GENERAL_ERROR

PANIC_SOFT_REBOOT

PANIC_HARD_REBOOT

PANIC_ASSERT_FAIL

PANIC_SSP

stack smashing protector failure

PANIC_UNDEFINED

kernel_defines.h::NORETURN void core_panic(panic.h::core_panic_t crash_code, const char * message)

Handle an unrecoverable error by halting or rebooting the system.

A numeric code indicating the failure reason can be given as the crash_code parameter.

Detailing the failure is possible using the message parameter. This function should serve a similar purpose as the panic() function of Unix/Linux kernels.

If the DEVELHELP macro is defined, the system will be halted; the system will be rebooted otherwise.

Parameters

crash_code:a unique code for identifying the crash reason message:a human readable reason for the crash

Return values

• this function never returns

void panic_arch(void)

architecture dependent handling of a panic case

This function gives the CPU the possibility to execute architecture dependent code in case of a severe error.
