ppc/pnv: add XSCOM infrastructure
On a real POWER8 system, the Pervasive Interconnect Bus (PIB) serves
as a backbone to connect different units of the system. The host
firmware connects to the PIB through a bridge unit, the
Alter-Display-Unit (ADU), which gives him access to all the chiplets
on the PCB network (Pervasive Connect Bus), the PIB acting as the root
of this network.
XSCOM (serial communication) is the interface to the sideband bus
provided by the POWER8 pervasive unit to read and write to chiplets
resources. This is needed by the host firmware, OPAL and to a lesser
extent, Linux. This is among others how the PCI Host bridges get
configured at boot or how the LPC bus is accessed.
To represent the ADU of a real system, we introduce a specific
AddressSpace to dispatch XSCOM accesses to the targeted chiplets. The
translation of an XSCOM address into a PCB register address is
slightly different between the P9 and the P8. This is handled before
the dispatch using a 8byte alignment for all.
To customize the device tree, a QOM InterfaceClass, PnvXScomInterface,
is provided with a populate() handler. The chip populates the device
tree by simply looping on its children. Therefore, each model needing
custom nodes should not forget to declare itself as a child at
instantiation time.

ppc/pnv: add XSCOM infrastructure
On a real POWER8 system, the Pervasive Interconnect Bus (PIB) serves
as a backbone to connect different units of the system. The host
firmware connects to the PIB through a bridge unit, the
Alter-Display-Unit (ADU), which gives him access to all the chiplets
on the PCB network (Pervasive Connect Bus), the PIB acting as the root
of this network.
XSCOM (serial communication) is the interface to the sideband bus
provided by the POWER8 pervasive unit to read and write to chiplets
resources. This is needed by the host firmware, OPAL and to a lesser
extent, Linux. This is among others how the PCI Host bridges get
configured at boot or how the LPC bus is accessed.
To represent the ADU of a real system, we introduce a specific
AddressSpace to dispatch XSCOM accesses to the targeted chiplets. The
translation of an XSCOM address into a PCB register address is
slightly different between the P9 and the P8. This is handled before
the dispatch using a 8byte alignment for all.
To customize the device tree, a QOM InterfaceClass, PnvXScomInterface,
is provided with a populate() handler. The chip populates the device
tree by simply looping on its children. Therefore, each model needing
custom nodes should not forget to declare itself as a child at
instantiation time.

ppc/pnv: restrict BMC object to the BMC simulator
Today, when a PowerNV guest runs, it uses the sensor definitions of
the BMC simulator to populate the device tree. But an external IPMI
BMC could also be used and, in that case, it is not (yet) possible to
retrieve the sensor list. Generating the OEM SEL event for shutdown or
reboot also does not make sense as it should be generated on the BMC
side.
This change allows a guest to use an 'ipmi-bmc-extern' backend to the
'isa-ipmi-bt' device and a 'chardev' for transport such as :
-chardev socket,id=ipmi0,host=localhost,port=9002,reconnect=10 \
-device ipmi-bmc-extern,id=bmc0,chardev=ipmi0 \
-device isa-ipmi-bt,bmc=bmc0,irq=10
and connect to a BMC simulator, the OpenIPMI ipmi_sim simulator for
instance.

hw/ppc/pnv: Use object_initialize_child for correct reference counting
As explained in commit aff39be0ed97:
Both functions, object_initialize() and object_property_add_child()
increase the reference counter of the new object, so one of the
references has to be dropped afterwards to get the reference
counting right. Otherwise the child object will not be properly
cleaned up when the parent gets destroyed.
Thus let's use now object_initialize_child() instead to get the
reference counting here right.
This patch was generated using the following Coccinelle script
(with a bit of manual fix-up for overly long lines):
@use_object_initialize_child@
expression parent_obj;
expression child_ptr;
expression child_name;
expression child_type;
expression child_size;
expression errp;
@@
(
- object_initialize(child_ptr, child_size, child_type);
+ object_initialize_child(parent_obj, child_name, child_ptr, child_size,
+ child_type, &error_abort, NULL);
... when != parent_obj
- object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), NULL);
...
?- object_unref(OBJECT(child_ptr));
|
- object_initialize(child_ptr, child_size, child_type);
+ object_initialize_child(parent_obj, child_name, child_ptr, child_size,
+ child_type, errp, NULL);
... when != parent_obj
- object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), errp);
...
?- object_unref(OBJECT(child_ptr));
)
While the object_initialize() function doesn't take an
'Error *errp' argument, the object_initialize_child() does.
Since this code is used when a machine is created (and is not
yet running), we deliberately choose to use the &error_abort
argument instead of ignoring errors if an object creation failed.
