int64_t opal_pci_eeh_freeze_status(uint64_t phb_id, uint64_t pe_number,
uint8_t *freeze_state,
uint16_t *pci_error_type,
uint64_t *phb_status);
.. note:: The ``phb_status`` parameter is deprecated as
of :ref:`skiboot-6.3-rc1`. Linux only ever passed in NULL,
and this was safe. Supplying a pointer was previously *unsafe*.
Always pass NULL.
Returns
-------
:ref:`OPAL_PARAMETER`
Invalid address or PHB.
:ref:`OPAL_UNSUPPORTED`
PHB does not support this operation.
:ref:`OPAL_HARDWARE`
Hardware prohibited getting status, OPAL maybe marked it as broken.
:ref:`OPAL_SUCCESS`
Retreived status.
