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

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

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.

Presenters of each thread. These are used to accept, return, forward

This area is modeled with a per-chip container memory region holding

its ICP registers using a memory subregion indexed by its PIR number
in the overall region.

Today, all the ICPs are created before the CPUs, stored in an array
under the sPAPR machine and linked to the CPU when the core threads
are realized. This modeling brings some complexity when a lookup in
the array is required and it can be simplified by allocating the ICPs
when the CPUs are.
This is the purpose of this proposal which introduces a new 'icp_type'
field under the machine and creates the ICP objects of the right type
(KVM or not) before the PowerPCCPU object are.
This change allows more cleanups : the removal of the icps array under
the sPAPR machine and the removal of the xics_get_cpu_index_by_dt_id()
helper.

Today, the ICPState array of the sPAPR machine is indexed with
'cpu_index' of the CPUState. This numbering of CPUs is internal to
QEMU and the guest only knows about what is exposed in the device
tree, that is the 'cpu_dt_id'. This is why sPAPR uses the helper
xics_get_cpu_index_by_dt_id() to do the mapping in a couple of places.
To provide a more generic XICS layer, we need to abstract the IRQ
'server' number and remove any assumption made on its nature. It
should not be used as a 'cpu_index' for lookups like xics_cpu_setup()
and xics_cpu_destroy() do.
To reach that goal, we choose to introduce a generic 'intc' backlink
under PowerPCCPU, and let the machine core init routine do the
ICPState lookup. The resulting object is passed on to xics_cpu_setup()
which does the store under PowerPCCPU. The IRQ 'server' number in XICS
is now generic. sPAPR uses 'cpu_dt_id' and PowerNV will use 'PIR'
number.
This also has the benefit of simplifying the sPAPR hcall routines
which do not need to do any ICPState lookups anymore.

For a little while around 4.9, Linux kernels that saw the radix bit in
ibm,pa-features would attempt to set up the MMU as if they were a
hypervisor, even if they were a guest, which would cause them to
crash.
Work around this by detecting pre-ISA 3.0 guests by their lack of that
bit in option vector 1, and then removing the radix bit from
ibm,pa-features. Note: This now requires regeneration of that node
after CAS negotiation.

Add the new node, /chosen/ibm,arch-vec-5-platform-support to the
device tree. This allows the guest to determine which modes are
supported by the hypervisor.
Update the option vector processing in h_client_architecture_support()
to handle the new MMU bits. This allows guests to request hash or
radix mode and QEMU to create the guest's HPT at this time if it is
necessary but hasn't yet been done. QEMU will terminate the guest if
it requests an unavailable mode, as required by the architecture.
Extend the ibm,pa-features node with the new ISA 3.0 values
and set the radix bit if KVM supports radix mode. This probably won't
be used directly by guests to determine the availability of radix mode
(that is indicated by the new node added above) but the architecture
requires that it be set when the hardware supports it.
If QEMU is using KVM, and KVM is capable of running in radix mode,
guests can be run in real-mode without allocating a HPT (because KVM
will use a minimal RPT). So in this case, we avoid creating the HPT
at reset time and later (during CAS) create it if it is necessary.
ISA 3.0 guests will now begin to call h_register_process_table(),
which has been added previously.

Introduce check function for setting read_only flags. Will return < 0 on
error, with appropriate Error value set. Does not alter any flags.

A few block drivers will set the BDS read_only flag from their
.bdrv_open() function. This means the bs->read_only flag could
be set after we enable copy_on_read, as the BDRV_O_COPY_ON_READ
flag check occurs prior to the call to bdrv->bdrv_open().
This adds an error return to bdrv_set_read_only(), and an error will be
return if we try to set the BDS to read_only while copy_on_read is
enabled.
This patch also changes the behavior of vvfat. Before, vvfat could
override the drive 'readonly' flag with its own, internal 'rw' flag.
For instance, this -drive parameter would result in a writable image:
"-drive format=vvfat,dir=/tmp/vvfat,rw,if=virtio,readonly=on"
This is not correct. Now, attempting to use the above -drive parameter
will result in an error (i.e., 'rw' is incompatible with 'readonly=on').

We have a helper wrapper for checking for the BDS read_only flag,
add a helper wrapper to set the read_only flag as well.

This patch adds support for getting and using a local copy of the dirty
bitmap.
memory_region_snapshot_and_clear_dirty() will create a snapshot of the
dirty bitmap for the specified range, clear the dirty bitmap and return
the copy. The returned bitmap can be a bit larger than requested, the
range is expanded so the code can copy unsigned longs from the bitmap
and avoid atomic bit update operations.
memory_region_snapshot_get_dirty() will return the dirty status of
pages, pretty much like memory_region_get_dirty(), but using the copy
returned by memory_region_copy_and_clear_dirty().

The FTGMAC100 device is an Ethernet controller with DMA function that
can be found on Aspeed SoCs (which include NCSI).
It is fully compliant with IEEE 802.3 specification for 10/100 Mbps
Ethernet and IEEE 802.3z specification for 1000 Mbps Ethernet and
includes Reduced Media Independent Interface (RMII) and Reduced
Gigabit Media Independent Interface (RGMII) interfaces. It adopts an
AHB bus interface and integrates a link list DMA engine with direct
M-Bus accesses for transmitting and receiving packets. It has
independent TX/RX fifos, supports half and full duplex (1000 Mbps mode
only supports full duplex), flow control for full duplex and
backpressure for half duplex.
The FTGMAC100 also implements IP, TCP, UDP checksum offloads and
supports IEEE 802.1Q VLAN tag insertion and removal. It offers
high-priority transmit queue for QoS and CoS applications
This model is backed with a RealTek 8211E PHY which is the chip found
on the AST2500 EVB. It is complete enough to satisfy two different
Linux drivers and a U-Boot driver. Not supported features are :
- IEEE 802.1Q VLAN
- High Priority Transmit Queue
- Wake-On-LAN functions
The code is based on the Coldfire Fast Ethernet Controller model.

Commit f0f272baf3a7 "xen: use libxendevice model to restrict operations"
added a command-line option (-xen-domid-restrict) to limit operations
using the libxendevicemodel API to a specified domid. The commit also
noted that the restriction would be extended to cover operations issued
via other xen libraries by subsequent patches.
My recent Xen patch [1] added a call to the xenforeignmemory API to allow
it to be restricted. This patch now makes use of that new call when the
-xen-domid-restrict option is passed.
