OPAL_TEST
=========
:ref:`OPAL_TEST` is a REQUIRED call for OPAL and conforming implementations MUST
have it.
It is designed to test basic OPAL call functionality.
Token:
.. code-block:: c
#define OPAL_TEST 0
Arguments
---------
::
uint64_t arg
Returns
-------
::
0xfeedf00d
Function
--------
:ref:`OPAL_TEST` MAY print a string to the OPAL log with the value of argument.
For example, the reference implementation (skiboot) implements :ref:`OPAL_TEST` as:
.. code-block:: c
static uint64_t opal_test_func(uint64_t arg)
{
printf("OPAL: Test function called with arg 0x%llx\n", arg);
return 0xfeedf00d;
}
