Detailed Description

Stop the system on an unrecoverable error.

The kernel logs the error with the address of the code that raised it, then hands over to pbl_fatal_error_handler(), which the platform implements.

switch (state) {
  case STATE_IDLE:
    break;
  case STATE_BUSY:
    pbl_panic("busy since %u", s_busy_since);
  default:
    pbl_panic();
}

Macro Definition Documentation

#define pbl_panic ( ... ) PBL_PANIC_SELECT(__VA_OPT__(MESSAGE))(__VA_ARGS__)

Stop the system.

Without arguments only the address of the caller is logged, the cheapest form, and the call is an expression.

Parameters

...	Optional printf-style message, a string literal, and its arguments.

void pbl_fatal_error_handler ( uintptr_t lr )

Handle a fatal error.

Implemented by the platform; the kernel calls it once the error is logged. It must not return, e.g. it saves a core dump and reboots.

Parameters

lr	Address of the code that raised the error.
