Hello,
The PowerNV and sPAPR machine use qdev_get_machine() and
get_system_memory() in some places. This is not a good modeling
pratice and it should be avoided. This series replaces the uses of
these routines with a set of QOM properties and aliases.
Thanks,
C.
Changes since v1:
- fixed a missing assert(chip->system_memory)
- introduced a XivePresenter link under XiveTCTX
Cédric Le Goater (5):
ppc/pnv: Modify the powerdown notifier to get the PowerNV machine
ppc/pnv: Introduce a "system-memory" property
ppc/pnv: Introduce a "xics" property alias under the PSI model
ppc/pnv: Introduce a "xics" property under the POWER8 chip
xive: Add a "presenter" link property to the TCTX object
Greg Kurz (8):
spapr/xive: Use device_class_set_parent_realize()
pnv/xive: Use device_class_set_parent_realize()
spapr, pnv, xive: Add a "xive-fabric" link to the XIVE router
xive: Use the XIVE fabric link under the XIVE router
ppc/pnv: Add an "nr-threads" property to the base chip class
ppc/pnv: Add a "pnor" const link property to the BMC internal
simulator
spapr/xive: Deduce the SpaprXive pointer from XiveTCTX::xptr
pnv/xive: Deduce the PnvXive pointer from XiveTCTX::xptr

POWER8 is the only chip using the XICS interface. Add a "xics" link
and a XICSFabric attribute under this chip to remove the use of
qdev_get_machine()

In order to get rid of qdev_get_machine(), first add a pointer to the
XIVE fabric under the XIVE router and make it configurable through a
QOM link property.
Configure it in the spapr and pnv machine. In the case of pnv, the XIVE
routers are under the chip, so this is done with a QOM alias property of
the POWER9 pnv chip.

From: Greg Kurz <groug@kaod.org>
Now that the spapr and pnv machines do set the "xive-fabric" link, the
use of the XIVE fabric pointer becomes mandatory. This is checked with
an assert() in a new realize hook. Since the XIVE router is realized at
machine init for the all the machine's life time, no risk to abort an
already running guest (ie. not a hotplug path).
This gets rid of a qdev_get_machine() call.

Set it at chip creation and forward it to the cores. This allows to drop

And use it instead of reaching out to the machine. This allows to get rid
of a call to qdev_get_machine() and to reduce the scope of another one so
that it is only used within the argument list of error_append_hint(). This
is an acceptable tradeoff compared to all it would require to know about
the maximum number of CPUs here without calling qdev_get_machine().
