Here's a respind of my first pull request for qemu-2.10, consisting of
assorted patches which have accumulated while qemu-2.9 stabilized.
Highlights are:
* Rework / cleanup of the XICS interrupt controller
* Substantial improvement to the 'powernv' machine type
- Includes an MMIO XICS version
* POWER9 support improvements
- POWER9 guests with KVM
- Partial support for POWER9 guests with TCG
* IOMMU and VFIO improvements
* Assorted minor changes
There are several IPMI patches here that aren't usually in my area of
maintenance, but there isn't a regular maintainer and these patches
are for the benefit of the powernv machine type.
This pull request supersedes my 2017-04-26 pull request. This new set
fixes a bug in one of the aforementioned IPMI patches which caused
clang sanitizer failures (and may have crashed on some libc / host
versions).

This patch exposes a new IPMI routine to query a sdr entry from the
sdr table maintained by the IPMI BMC simulator. The API is very

the same way to query one or all sdrs.
A typical use would be to loop on the sdrs to build nodes of a device

The OCC is an on-chip microcontroller based on a ppc405 core used
for various power management tasks. It comes with a pile of additional
hardware sitting on the PIB (aka XSCOM bus). At this point we don't
emulate it (nor plan to do so). However there is one facility which
is provided by the surrounding hardware that we do need, which is the
interrupt generation facility. OPAL uses it to send itself interrupts
under some circumstances and there are other uses around the corner.
So this implement just enough to support this.

The Processor Service Interface (PSI) Controller is one of the engines
of the "Bridge" unit which connects the different interfaces to the
Power Processor.
This adds just enough of the PSI bridge to handle various on-chip and
the one external interrupt. The rest of PSI has to do with the link to
the IBM FSP service processor which we don't plan to emulate (not used
on OpenPower machines).
The ics_get() and ics_resend() handlers of the XICSFabric interface of
the PowerNV machine are now defined to handle the Interrupt Control
Source of PSI. The InterruptStatsProvider interface is also modified
to dump the new ICS.

This provides to a PowerNV chip (POWER8) access to the Interrupt
Management area, which contains the registers of the Interrupt Control
Presenters of each thread. These are used to accept, return, forward
interrupts in the system.
This area is modeled with a per-chip container memory region holding
all the ICP registers. Each thread of a chip is then associated with
its ICP registers using a memory subregion indexed by its PIR number
in the overall region.
The device tree is populated accordingly.
