.. _OPAL_GET_COMPLETION_TOKEN_STATUS:
OPAL_GET_COMPLETION_TOKEN_STATUS
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In the before time, long-long ago, there existed something called OPAL before
the incarnation we know today. Presumably, this long forgotten incarnation
had a call called this.
This call has never been implemented, and never will be.
.. _OPAL_PCI_SHPC:
OPAL_PCI_SHPC
^^^^^^^^^^^^^
A remnant of a long forgotten incarnation of OPAL. Never implemented, never
will be.
.. _OPAL_PCI_SET_PHB_TABLE_MEMORY:
OPAL_PCI_SET_PHB_TABLE_MEMORY
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
A remnant of an old API design. Never implemented, never used. Only ever
returned :ref:`OPAL_UNSUPPORTED`, now the call is not implemented at all.
.. _OPAL_PCI_GET_XIVE_REISSUE:
OPAL_PCI_GET_XIVE_REISSUE
^^^^^^^^^^^^^^^^^^^^^^^^^
A remnant of something prior to OPALv3. Never implemented in skiboot and never
used by anyone. Returend :ref:`OPAL_UNSUPPORTED` until :ref:`skiboot-6.4`, where
it was removed.
.. _OPAL_PCI_SET_XIVE_REISSUE:
OPAL_PCI_SET_XIVE_REISSUE
^^^^^^^^^^^^^^^^^^^^^^^^^
A remnant of something prior to OPALv3. Never implemented in skiboot and never
used by anyone. Returend :ref:`OPAL_UNSUPPORTED` until :ref:`skiboot-6.4`, where
it was removed.
.. _OPAL_PCI_FENCE_PHB:
OPAL_PCI_FENCE_PHB
^^^^^^^^^^^^^^^^^^
Never implemented.
.. _OPAL_PCI_MASK_PE_ERROR:
OPAL_PCI_MASK_PE_ERROR
^^^^^^^^^^^^^^^^^^^^^^
Never implemented.
.. _OPAL_SET_SLOT_LED_STATUS:
OPAL_SET_SLOT_LED_STATUS
^^^^^^^^^^^^^^^^^^^^^^^^
Never implemented.
.. _OPAL_SET_SYSTEM_ATTENTION_LED:
OPAL_SET_SYSTEM_ATTENTION_LED
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Never implemented.
.. _OPAL_RESERVED1:
OPAL_RESERVED1
^^^^^^^^^^^^^^
Reserved for future use, but never used.
.. _OPAL_RESERVED2:
OPAL_RESERVED2
^^^^^^^^^^^^^^
Reserved for future use, but never used.
.. _OPAL_ELOG_SEND:
OPAL_ELOG_SEND
^^^^^^^^^^^^^^
Brielfy present prior to the first public release of OPAL. Never used in any
public kernel tree. If this functionality were to ever be implemented, it'd
appear as :ref:`OPAL_ELOG_WRITE` rather than this call.
.. _OPAL_PCI_GET_PHB_DIAG_DATA:
OPAL_PCI_GET_PHB_DIAG_DATA
==========================
This call was introduced and functionally removed (all backends for it were)
before the first public opal release. It has not been used since Linux 3.11-rc1.
Considering the state of EEH in such old kernels and firmware, removing the
remnants of this call is considered safe. If for some bizarre reason such an
old kernel is run on :ref:`skiboot-6.4` or later, an :ref:`OPAL_PARAMETER` error
will be returned instead of :ref:`OPAL_UNSUPPORTED`.
It is replaced by :ref:`OPAL_PCI_GET_PHB_DIAG_DATA2` instead.
.. _OPAL_GET_XIVE_SOURCE:
OPAL_GET_XIVE_SOURCE
^^^^^^^^^^^^^^^^^^^^
While this call was technically implemented by skiboot, no code has ever called
it, and it was only ever implemented for the p7ioc-phb back-end (i.e. POWER7).
Since this call was unused in Linux, and that POWER7 with OPAL was only ever
available internally, it was determined that it was safe to remove this call as
of :ref:`skiboot-6.4`.
.. _OPAL_WRITE_OPPANEL:
OPAL_WRITE_OPPANEL
^^^^^^^^^^^^^^^^^^
Never in a released version, use :ref:`OPAL_WRITE_OPPANEL_ASYNC`.
.. _OPAL_OLD_I2C_REQUEST:
OPAL_OLD_I2C_REQUEST
^^^^^^^^^^^^^^^^^^^^
Never used. Only existing briefly in the :ref:`skiboot-4.0` development cycle.
.. _OPAL_REGISTER_OPAL_EXCEPTION_HANDLER:
OPAL_REGISTER_OPAL_EXCEPTION_HANDLER
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: c
#define OPAL_REGISTER_OPAL_EXCEPTION_HANDLER 22
int64_t opal_register_exc_handler(uint64_t opal_exception __unused,
uint64_t handler_address __unused,
uint64_t glue_cache_line __unused);
This call existed for a very short period of time and only ever worked with Big
Endian host operating systems. The idea was that OPAL would handle HMIs and
an OS could (if it chose to) register a handler for them. This call is not
required since the introduction of :ref:`OPAL_HANDLE_HMI` and all machines that
ever shipped without :ref:`OPAL_HANDLE_HMI` have a firmware update that
supports it. For IBM Tuleta machines, this was FW810.20 (released Oct 2014)
that had :ref:`OPAL_HANDLE_HMI` support.
This call was removed in :ref:`skiboot-5.0` and now just
returns :ref:`OPAL_UNSUPPORTED`.
Use of the :ref:`OPAL_HANDLE_HMI` call was introduced in Linux 3.17.
.. _OPAL_PCI_SET_HUB_TCE_MEMORY:
OPAL_PCI_SET_HUB_TCE_MEMORY
^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: c
#define OPAL_PCI_SET_HUB_TCE_MEMORY 11
int64_t opal_pci_set_hub_tce_memory(uint64_t hub_id,
uint64_t tce_mem_addr __unused,
uint64_t tce_mem_size __unused);
This call was only ever relevant for p5ioc based POWER7 systems. These were
never available with OPAL outside of IBM development.
Support for POWER7 systems with p5ioc was dropped in :ref:`skiboot-5.2.0`,
and these systems were only ever used with OPAL inside IBM for development
and bring-up purposes.
Support for p5ioc was removed from the Linux kernel in v4.6-rc1.
.. _OPAL_PCI_SET_PHB_TCE_MEMORY:
OPAL_PCI_SET_PHB_TCE_MEMORY
^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: c
#define OPAL_PCI_SET_PHB_TCE_MEMORY 12
int64_t opal_pci_set_phb_tce_memory(uint64_t phb_id,
uint64_t tce_mem_addr,
uint64_t tce_mem_size);
This call was only ever relevant for p5ioc based POWER7 systems. These were
never available with OPAL outside of IBM development.
Support for POWER7 systems with p5ioc was dropped in :ref:`skiboot-5.2.0`,
and these systems were only ever used with OPAL inside IBM for development
and bring-up purposes.
Support for p5ioc was removed from the Linux kernel in v4.6-rc1.
.. _OPAL_PCI_SET_MVE:
OPAL_PCI_SET_MVE
^^^^^^^^^^^^^^^^
Dead code, as the callback did nothing after the P7IOC code was removed in
skiboot 6.4. Removed in :ref:`skiboot-7.1`.
.. _OPAL_PCI_SET_MVE_ENABLE:
OPAL_PCI_SET_MVE_ENABLE
^^^^^^^^^^^^^^^^^^^^^^^
Dead code, as the callback did nothing after the P7IOC code was removed in
skiboot 6.4. Removed in :ref:`skiboot-7.1`.
Future Calls
------------
.. _OPAL_ELOG_WRITE:
OPAL_ELOG_WRITE
^^^^^^^^^^^^^^^
May be implemented in the future to complement the :ref:`OPAL_ELOG_READ` call.
