.. _OPAL_PCI_SET_XIVE_PE:
OPAL_PCI_SET_XIVE_PE
====================
.. code-block:: c
#define OPAL_PCI_SET_XIVE_PE 37
int64_t opal_pci_set_xive_pe(uint64_t phb_id, uint64_t pe_number, uint32_t xive_num);
**WARNING:** following documentation is from old sources, and is possibly
not representative of OPALv3 as implemented by skiboot. This should be
used as a starting point for full documentation.
The host calls this function to bind a PE to an XIVE. Only that PE may then
signal an MSI that selects this XIVE.
``phb_id``
is the value from the PHB node ibm,opal-phbid property.
``pe_number``
is the index of a PE, from 0 to ibm,opal-num-pes minus 1.
``xive_number``
is the index, from 0 to ibm,opal,ibm-num-msis minus (num_lsis+1)
This call maps the XIVR indexed by xive_num to the PE specified by
pe_number. For ibm,opal-ioda HW, the pe_number must match the pe_number
set in the MVE.
Return value:
.. code-block:: c
if (!phb)
return OPAL_PARAMETER;
if (!phb->ops->set_xive_pe)
return OPAL_UNSUPPORTED;
