Function Documentation

error_to_string()

const char * error_to_string

(

long

code

)

Converts a numeric error code into a human-readable string.

This function maps internal kernel error constants (e.g., ERROR_CODE_NOT_EL1) to descriptive string literals. It is primarily used by the panic handler to provide diagnostic feedback over UART when a fatal error occurs.

Parameters

code	The numeric error code triggered by the kernel or bootloader.

Returns

A pointer to a constant null-terminated string representing the error. Returns "UNKNOWN" if the code is not recognized.

Note

This function is designed to be safe for use during early boot or panic states; it does not allocate memory and relies solely on strings stored in the .rodata section.
