The PPC 405 CPU is a system-on-a-chip, so all 405 machines are very similar,
except for some external periphery. However, the periphery of the ``taihu``
machine is hardly emulated at all (e.g. neither the LCD nor the USB part had
been implemented), so there is not much value added by this board. Use the
``ref405ep`` machine instead.

sPAPR hypervisor calls
----------------------
When used with the ``pseries`` machine type, ``qemu-system-ppc64`` implements
a set of hypervisor calls (a.k.a. hcalls) defined in the `Linux on Power
Architecture Reference document (LoPAR)
<https://cdn.openpowerfoundation.org/wp-content/uploads/2020/07/LoPAR-20200812.pdf>`_.
This document is a subset of the Power Architecture Platform Reference (PAPR+)
specification (IBM internal only), which is what PowerVM, the IBM proprietary
hypervisor, adheres to.
The subset in LoPAR is selected based on the requirements of Linux as a guest.
In addition to those calls, we have added our own private hypervisor
calls which are mostly used as a private interface between the firmware
running in the guest and QEMU.
All those hypercalls start at hcall number 0xf000 which correspond
to an implementation specific range in PAPR.
H_RTAS (0xf000)
^^^^^^^^^^^^^^^
RTAS stands for Run-Time Abstraction Sercies and is a set of runtime services
generally provided by the firmware inside the guest to the operating system. It
predates the existence of hypervisors (it was originally an extension to Open
Firmware) and is still used by PAPR and LoPAR to provide various services that
are not performance sensitive.
We currently implement the RTAS services in QEMU itself. The actual RTAS
"firmware" blob in the guest is a small stub of a few instructions which
calls our private H_RTAS hypervisor call to pass the RTAS calls to QEMU.
Arguments:
``r3``: ``H_RTAS (0xf000)``
``r4``: Guest physical address of RTAS parameter block.
Returns:
``H_SUCCESS``: Successfully called the RTAS function (RTAS result will have
been stored in the parameter block).
``H_PARAMETER``: Unknown token.
H_LOGICAL_MEMOP (0xf001)
^^^^^^^^^^^^^^^^^^^^^^^^
When the guest runs in "real mode" (in powerpc terminology this means with MMU
disabled, i.e. guest effective address equals to guest physical address), it
only has access to a subset of memory and no I/Os.
PAPR and LoPAR provides a set of hypervisor calls to perform cacheable or
non-cacheable accesses to any guest physical addresses that the
guest can use in order to access IO devices while in real mode.
This is typically used by the firmware running in the guest.
However, doing a hypercall for each access is extremely inefficient
(even more so when running KVM) when accessing the frame buffer. In
that case, things like scrolling become unusably slow.
This hypercall allows the guest to request a "memory op" to be applied
to memory. The supported memory ops at this point are to copy a range
of memory (supports overlap of source and destination) and XOR which
is used by our SLOF firmware to invert the screen.
Arguments:
``r3 ``: ``H_LOGICAL_MEMOP (0xf001)``
``r4``: Guest physical address of destination.
``r5``: Guest physical address of source.
``r6``: Individual element size, defined by the binary logarithm of the
desired size. Supported values are:
``0`` = 1 byte
``1`` = 2 bytes
``2`` = 4 bytes
``3`` = 8 bytes
``r7``: Number of elements.
``r8``: Operation. Supported values are:
``0``: copy
``1``: xor
Returns:
``H_SUCCESS``: Success.
``H_PARAMETER``: Invalid argument.

Current acceleration status
---------------------------
KVM acceleration in Linux Power hosts is provided by the kvm-hv and
kvm-pr modules. kvm-hv is adherent to PAPR and it's not compliant with
powernv. kvm-pr in theory could be used as a valid accel option but
this isn't supported by kvm-pr at this moment.
To spare users from dealing with not so informative errors when attempting
to use accel=kvm, the powernv machine will throw an error informing that
KVM is not supported. This can be revisited in the future if kvm-pr (or
any other KVM alternative) is usable as KVM accel for this machine.

pSeries family boards (``pseries``)
===================================
The Power machine para-virtualized environment described by the `Linux on Power
Architecture Reference document (LoPAR)
<https://openpowerfoundation.org/wp-content/uploads/2020/07/LoPAR-20200812.pdf>`_
is called pSeries. This environment is also known as sPAPR, System p guests, or
simply Power Linux guests (although it is capable of running other operating
systems, such as AIX).
Even though pSeries is designed to behave as a guest environment, it is also
capable of acting as a hypervisor OS, providing, on that role, nested
virtualization capabilities.
Supported devices
-----------------
* Multi processor support for many Power processors generations: POWER7,
POWER7+, POWER8, POWER8NVL, POWER9, and Power10. Support for POWER5+ exists,
but its state is unknown.
* Interrupt Controller, XICS (POWER8) and XIVE (POWER9 and Power10)
* vPHB PCIe Host bridge.
* vscsi and vnet devices, compatible with the same devices available on a
PowerVM hypervisor with VIOS managing LPARs.
* Virtio based devices.
* PCIe device pass through.
Missing devices
---------------
* SPICE support.
Firmware
--------
`SLOF <https://github.com/aik/SLOF>`_ (Slimline Open Firmware) is an
implementation of the `IEEE 1275-1994, Standard for Boot (Initialization
Configuration) Firmware: Core Requirements and Practices
<https://standards.ieee.org/standard/1275-1994.html>`_.
QEMU includes a prebuilt image of SLOF which is updated when a more recent
version is required.
Build directions
----------------
.. code-block:: bash
./configure --target-list=ppc64-softmmu && make
Running instructions
--------------------
Someone can select the pSeries machine type by running QEMU with the following
options:
.. code-block:: bash
qemu-system-ppc64 -M pseries <other QEMU arguments>
sPAPR devices
-------------
The sPAPR specification defines a set of para-virtualized devices, which are
also supported by the pSeries machine in QEMU and can be instantiated with the
``-device`` option:
* ``spapr-vlan`` : a virtual network interface.
* ``spapr-vscsi`` : a virtual SCSI disk interface.
* ``spapr-rng`` : a pseudo-device for passing random number generator data to the
guest (see the `H_RANDOM hypercall feature
<https://wiki.qemu.org/Features/HRandomHypercall>`_ for details).
* ``spapr-vty``: a virtual teletype.
* ``spapr-pci-host-bridge``: a PCI host bridge.
* ``tpm-spapr``: a Trusted Platform Module (TPM).
* ``spapr-tpm-proxy``: a TPM proxy.
These are compatible with the devices historically available for use when
running the IBM PowerVM hypervisor with LPARs.
However, since these devices have originally been specified with another
hypervisor and non-Linux guests in mind, you should use the virtio counterparts
(virtio-net, virtio-blk/scsi and virtio-rng for instance) if possible instead,
since they will most probably give you better performance with Linux guests in a
QEMU environment.
The pSeries machine in QEMU is always instantiated with the following devices:
* A NVRAM device (``spapr-nvram``).
* A virtual teletype (``spapr-vty``).
* A PCI host bridge (``spapr-pci-host-bridge``).
Hence, it is not needed to add them manually, unless you use the ``-nodefaults``
command line option in QEMU.
In the case of the default ``spapr-nvram`` device, if someone wants to make the
contents of the NVRAM device persistent, they will need to specify a PFLASH
device when starting QEMU, i.e. either use
``-drive if=pflash,file=<filename>,format=raw`` to set the default PFLASH
device, or specify one with an ID
(``-drive if=none,file=<filename>,format=raw,id=pfid``) and pass that ID to the
NVRAM device with ``-global spapr-nvram.drive=pfid``.
sPAPR specification
^^^^^^^^^^^^^^^^^^^
The main source of documentation on the sPAPR standard is the `Linux on Power
Architecture Reference document (LoPAR)
<https://openpowerfoundation.org/wp-content/uploads/2020/07/LoPAR-20200812.pdf>`_.
However, documentation specific to QEMU's implementation of the specification
can also be found in QEMU documentation:
.. toctree::
:maxdepth: 1
../../specs/ppc-spapr-hcalls.rst
../../specs/ppc-spapr-numa.rst
../../specs/ppc-spapr-xive.rst
Other documentation available in QEMU docs directory:
* Hot plug (``/docs/specs/ppc-spapr-hotplug.txt``).
* Hypervisor calls needed by the Ultravisor
(``/docs/specs/ppc-spapr-uv-hcalls.txt``).
Switching between the KVM-PR and KVM-HV kernel module
-----------------------------------------------------
Currently, there are two implementations of KVM on Power, ``kvm_hv.ko`` and
``kvm_pr.ko``.
If a host supports both KVM modes, and both KVM kernel modules are loaded, it is
possible to switch between the two modes with the ``kvm-type`` parameter:
* Use ``qemu-system-ppc64 -M pseries,accel=kvm,kvm-type=PR`` to use the
``kvm_pr.ko`` kernel module.
* Use ``qemu-system-ppc64 -M pseries,accel=kvm,kvm-type=HV`` to use ``kvm_hv.ko``
instead.
KVM-PR
^^^^^^
KVM-PR uses the so-called **PR**\ oblem state of the PPC CPUs to run the guests,
i.e. the virtual machine is run in user mode and all privileged instructions
trap and have to be emulated by the host. That means you can run KVM-PR inside
a pSeries guest (or a PowerVM LPAR for that matter), and that is where it has
originated, as historically (prior to POWER7) it was not possible to run Linux
on hypervisor mode on a Power processor (this function was restricted to
PowerVM, the IBM proprietary hypervisor).
Because all privileged instructions are trapped, guests that use a lot of
privileged instructions run quite slow with KVM-PR. On the other hand, because
of that, this kernel module can run on pretty much every PPC hardware, and is
able to emulate a lot of guests CPUs. This module can even be used to run other
PowerPC guests like an emulated PowerMac.
As KVM-PR can be run inside a pSeries guest, it can also provide nested
virtualization capabilities (i.e. running a guest from within a guest).
It is important to notice that, as KVM-HV provides a much better execution
performance, maintenance work has been much more focused on it in the past
years. Maintenance for KVM-PR has been minimal.
In order to run KVM-PR guests with POWER9 processors, someone will need to start
QEMU with ``kernel_irqchip=off`` command line option.
KVM-HV
^^^^^^
KVM-HV uses the hypervisor mode of more recent Power processors, that allow
access to the bare metal hardware directly. Although POWER7 had this capability,
it was only starting with POWER8 that this was officially supported by IBM.
Originally, KVM-HV was only available when running on a PowerNV platform (a.k.a.
Power bare metal). Although it runs on a PowerNV platform, it can only be used
to start pSeries guests. As the pSeries guest doesn't have access to the
hypervisor mode of the Power CPU, it wasn't possible to run KVM-HV on a guest.
This limitation has been lifted, and now it is possible to run KVM-HV inside
pSeries guests as well, making nested virtualization possible with KVM-HV.
As KVM-HV has access to privileged instructions, guests that use a lot of these
can run much faster than with KVM-PR. On the other hand, the guest CPU has to be
of the same type as the host CPU this way, e.g. it is not possible to specify an
embedded PPC CPU for the guest with KVM-HV. However, there is at least the
possibility to run the guest in a backward-compatibility mode of the previous
CPUs generations, e.g. you can run a POWER7 guest on a POWER8 host by using
``-cpu POWER8,compat=power7`` as parameter to QEMU.
Modules support
---------------
As noticed in the sections above, each module can run in a different
environment. The following table shows with which environment each module can
run. As long as you are in a supported environment, you can run KVM-PR or KVM-HV
nested. Combinations not shown in the table are not available.
