int64_t opal_pci_reset(uint64_t id, uint8_t reset_scope, uint8_t assert_state);
Kick off the requested PCI reset operation. This starts a state machine off to
perform the requested operation. This call will return how many milliseconds to
wait before calling back into :ref:`OPAL_PCI_POLL`. An OS can
call :ref:`OPAL_PCI_POLL` earlier, but it is unlikely any progress will have
been made.
Returns
-------
:ref:`OPAL_PARAMETER`
Invalid ``id``, ``reset_scope``, or ``assert_state``.
:ref:`OPAL_UNSUPPORTED`
Operation is unsupported on ``id``.
value > 0
How many ms to wait for the state machine to crank.
Call :ref:`OPAL_PCI_POLL` to crank the state machine further.
