This reverts commit dc0ae76770.
Disabling the shpc controller has an undesired side effect.
The PCI bridge remains with no attached devices at boot time,
and the guest operating systems do not allocate any resources
for it, leaving the bridge unusable. Note that the behaviour
is dictated by the pci bridge specification.
Revert the commit and leave the shpc controller even if is not
actually used by any architecture. Slot 0 remains unusable at boot time.
Keep shpc off for QEMU 2.9 machines.

cannot_instantiate_with_device_add_yet was introduced by commit
efec3dd631 to replace no_user. It was
supposed to be a temporary measure.
When it was introduced, we had 54
cannot_instantiate_with_device_add_yet=true lines in the code.
Today (3 years later) this number has not shrunk: we now have
57 cannot_instantiate_with_device_add_yet=true lines. I think it
is safe to say it is not a temporary measure, and we won't see
the flag go away soon.
Instead of a long field name that misleads people to believe it
is temporary, replace it a shorter and less misleading field:
user_creatable.

Originally CPU threads were by default assigned in
round-robin fashion. However it was causing issues in
guest since CPU threads from the same socket/core could
be placed on different NUMA nodes.
Commit fb43b73b (pc: fix default VCPU to NUMA node mapping)
fixed it by grouping threads within a socket on the same node
introducing cpu_index_to_socket_id() callback and commit
20bb648d (spapr: Fix default NUMA node allocation for threads)
reused callback to fix similar issues for SPAPR machine
even though socket doesn't make much sense there.
As result QEMU ended up having 3 default distribution rules
used by 3 targets /virt-arm, spapr, pc/.
In effort of moving NUMA mapping for CPUs into possible_cpus,
generalize default mapping in numa.c by making boards decide
on default mapping and let them explicitly tell generic
numa code to which node a CPU thread belongs to by replacing
cpu_index_to_socket_id() with @cpu_index_to_instance_props()
which provides default node_id assigned by board to specified
cpu_index.

When there are more nodes than available memory to put the minimum
allowed memory by node, all the memory is put on the last node.
This is because we put (ram_size / nb_numa_nodes) &
~((1 << mc->numa_mem_align_shift) - 1); on each node, and in this
case the value is 0. This is particularly true with pseries,
as the memory must be aligned to 256MB.
To avoid this problem, this patch uses an error diffusion algorithm [1]
to distribute equally the memory on nodes.
We introduce numa_auto_assign_ram() function in MachineClass
to keep compatibility between machine type versions.
The legacy function is used with pseries-2.9, pc-q35-2.9 and
pc-i440fx-2.9 (and previous), the new one with all others.
Example:
qemu-system-ppc64 -S -nographic -nodefaults -monitor stdio -m 1G -smp 8 \
-numa node -numa node -numa node \
-numa node -numa node -numa node
Before:

node 0 cpus: 0 6
node 0 size: 0 MB
node 1 cpus: 1 7

node 2 cpus: 2

Kernel commit 17d48610ae0f ("KVM: PPC: Book 3S: XICS: Implement ICS
P/Q states") added new bits to the state used by KVM IRQs. Currently,
QEMU does not preserve these bits, so migrating (or otherwise saving
and restoring) the guest state causes the P and Q bits to be cleared.
Clearing the P bit has no effect, because the kernel will set it based
on other data, but the loss of a set Q bit will cause a lost
interrupt.
This patch preserves the P and Q bits, correcting the problem.

Since 2.7 commit (b2a575a Add optionrom compatible with fw_cfg DMA version)
regressed migration during firmware exection time by
abusing fwcfg.dma_enabled property to decide loading
dma version of option rom AND by mistake disabling DMA
for 2.6 and earlier globally instead of only for option rom.
so 2.6 machine type guest is broken when it already runs
firmware in DMA mode but migrated to qemu-2.7(pc-2.6)
at that time;
a) qemu-2.6:pc2.6 (fwcfg.dma=on,firmware=dma,oprom=ioport)
b) qemu-2.7:pc2.6 (fwcfg.dma=off,firmware=ioport,oprom=ioport)
to: a b
from
a OK FAIL
b OK OK
So we currently have broken forward migration from
qemu-2.6 to qemu-2.[789] that however could be fixed
for 2.10 by re-enabling DMA for 2.[56] machine types
and allowing dma capable option rom only since 2.7.
As result qemu should end up with:
c) qemu-2.10:pc2.6 (fwcfg.dma=on,firmware=dma,oprom=ioport)
to: a b c
from
a OK FAIL OK
b OK OK OK
c OK FAIL OK
where forward migration from qemu-2.6 to qemu-2.10 should
work again leaving only qemu-2.[789]:pc-2.6 broken.

Our current ACPI table generation code limits the placement of ACPI
tables to 32-bit addressable memory, in order to be able to emit the
root pointer (RSDP) and root table (RSDT) using table types from the
ACPI 1.0 days.
Since ARM was not supported by ACPI before version 5.0, it makes sense
to lift this restriction. This is not crucial for mach-virt, which is
guaranteed to have some memory available below the 4 GB mark, but it
is a nice to have for QEMU machines that do not have any 32-bit
addressable memory, which is not uncommon for real world 64-bit ARM
systems.
Since we already emit a version of the RSDP root pointer that has a
secondary 64-bit wide address field for the 64-bit root table (XSDT),
all we need to do is replace the RSDT generation with the generation
of an XSDT table, and use a different slot in the FADT table to refer
to the DSDT.

This introduces the input and output handlers for 3270 device, setting
up the data tunnel among guest kernel, qemu and the 3270 client.
After the client connected and TN3270 handshake done, signal the not-ready
to ready status by an unsolicited device-end interrupt, and then the 3270
data stream could be handled correctly between the channel and socket.
Multiple commands generated by "Reset" key on x3270 are not supported now,

This updates the FADT generated for x86/64 machine types from Revision 1 to 3. (Based on ACPI standard 2.0 instead of 1.0) The intention is to expose the reset register information to guest operating systems which require it, specifically OS X/macOS. Revision 1 FADTs do not contain the fields relating to the reset register.
The new layout and contents remains backwards-compatible with operating systems which only support ACPI 1.0, as the existing fields are not modified by this change, as the 64-bit and 32-bit variants are allowed to co-exist according to the ACPI 2.0 standard. No regressions became apparent in tests with a range of Windows (XP-10) and Linux versions.
The BIOS tables test suite's FADT checksum test has also been updated to reflect the new FADT layout and content.

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

Skiboot, the firmware for the PowerNV platform, expects the BMC to
provide some specific IPMI sensors. These sensors are exposed in the
device tree and their values are updated by the firmware at boot time.
Sensors of interest are :
"FW Boot Progress"
"Boot Count"

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

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.
