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 OPAL_PCI_POLL. An OS can call OPAL_PCI_POLL earlier, but it is unlikely any progress will have been made.

Returns

OPAL_PARAMETER
Invalid id, reset_scope, or assert_state.
OPAL_UNSUPPORTED
Operation is unsupported on id.
value > 0
How many ms to wait for the state machine to crank. Call OPAL_PCI_POLL to crank the state machine further.
