7f9fe3f02d spapr_cpu_core: migrate VPA related state
QEMU implements the "Shared Processor LPAR" (SPLPAR) option, which allows
the hypervisor to time-slice a physical processor into multiple virtual
processor. The intent is to allow more guests to run, and to optimize
processor utilization.

The guest OS can cede idle VCPUs, so that their processing capacity may
be used by other VCPUs, with the H_CEDE hcall. The guest OS can also
optimize spinlocks, by confering the time-slice of a spinning VCPU to the
spinlock holder if it's currently notrunning, with the H_CONFER hcall.

Both hcalls depend on a "Virtual Processor Area" (VPA) to be registered
by the guest OS, generally during early boot. Other per-VCPU areas can
be registered: the "SLB Shadow Buffer" which allows a more efficient
dispatching of VCPUs, and the "Dispatch Trace Log Buffer" (DTL) which
is used to compute time stolen by the hypervisor. Both DTL and SLB Shadow
areas depend on the VPA to be registered.

The VPA/SLB Shadow/DTL are state that QEMU should migrate, but this doesn't
happen, for no apparent reason other than it was just never coded. This
causes the features listed above to stop working after migration, and it
breaks the logic of the H_REGISTER_VPA hcall in the destination.

The VPA is set at the guest request, ie, we don't have to migrate
it before the guest has actually set it. This patch hence adds an
"spapr_cpu/vpa" subsection to the recently introduced per-CPU machine
data migration stream.

Since DTL and SLB Shadow are optional and both depend on VPA, they get
their own subsections "spapr_cpu/vpa/slb_shadow" and "spapr_cpu/vpa/dtl"
hanging from the "spapr_cpu/vpa" subsection.

Note that this won't break migration to older QEMUs. Is is already handled
by only registering the vmstate handler for per-CPU data with newer machine
types.

b94020268e spapr_cpu_core: migrate per-CPU data
A per-CPU machine data pointer was recently added to PowerPCCPU. The
motivation is to to hide platform specific details from the core CPU
code. This per-CPU data can hold state which is relevant to the guest
though, eg, Virtual Processor Areas, and we should migrate this state.

This patch adds the plumbing so that we can migrate the per-CPU data
for PAPR guests. We only do this for newer machine types for the sake
of backward compatibility. No state is migrated for the moment: the
vmstate_spapr_cpu_state structure will be populated by subsequent
patches.

04026890f2 ppc/pnv: introduce a new isa_create() operation to the chip model
This moves the details of the ISA bus creation under the LPC model but
more important, the new PnvChip operation will let us choose the chip
class to use when we introduce the different chip classes for Power9
and Power8. It hides away the processor chip controllers from the
machine.

b55a06df4f ps2: check PS2Queue wptr pointer in post_load routine
In commit 802cbcb730, most issues have been fixed when qemu guest
migration. But the queue size still need to check whether is equal to
PS2_QUEUE_SIZE. If yes, the wptr should set as 0. Or, wptr would larger
than PS2_QUEUE_SIZE and never come back when ps2_queue_noirq is called.
This could lead to OOB access, add check to avoid it.

995b30179b hw/display: add ramfb, a simple boot framebuffer living in guest ram
The boot framebuffer is expected to be configured by the firmware, so it
uses fw_cfg as interface.  Initialization goes as follows:

  (1) Check whenever etc/ramfb is present.
  (2) Allocate framebuffer from RAM.
  (3) Fill struct RAMFBCfg, write it to etc/ramfb.

Done.  You can write stuff to the framebuffer now, and it should appear
automagically on the screen.

Note that this isn't very efficient because it does a full display
update on each refresh.  No dirty tracking.  Dirty tracking would have
to be active for the whole ram slot, so that wouldn't be very efficient
either.  For a boot display which is active for a short time only this
isn't a big deal.  As permanent guest display something better should be
used (if possible).

This is the ramfb core code.  Some windup is needed for display devices
which want have a ramfb boot display.

Right now the IPL device always starts from address 0x10000 (the usual
Linux entry point). To run other guests (e.g. test programs) it is
useful to use the IPL PSW from address 0. We can use the Linux magic
at 0x10008 to decide.

9a51c9ee6c vfio-ccw: add force unlimited prefetch property
There is at least one guest (OS) such that although it does not rely on
the guarantees provided by ORB 1 word 9 bit (aka unlimited prefetch, aka
P bit) not being set, it fails to tell this to the machine.

Usually this ain't a big deal, as the original purpose of the P bit is to
allow for performance optimizations. vfio-ccw however can not provide the
guarantees required if the bit is not set.

It is not possible to implement support for the P bit not set without
transitioning to lower level protocols for vfio-ccw.  So let's give the
user the opportunity to force setting the P bit, if the user knows this
is safe.  For self modifying channel programs forcing the P bit is not
safe.  If the P bit is forced for a self modifying channel program things
are expected to break in strange ways.

Let's also avoid warning multiple about P bit not set in the ORB in case
P bit is not told to be forced, and designate the affected vfio-ccw
device.

844afc54ae spapr: fix xics_system_init() error path
Commit 3d85885a1b tried to fix error handling, but it actually
went into the wrong direction by dropping the local Error *.

In the default KVM case, the rationale is to try the in-kernel XICS first,
and if not possible, to fallback to userland XICS. Passing errp everywhere
makes this fallback impossible if errp is &error_fatal (which happens to
be the case). And anyway, if the caller would pass a regular &local_err,
things would be worse: we could possibly pass an already set *errp to
error_setg() and crash, or return an error even in case of success.

So we definitely need a local Error * and only propagate it when we're
done with the fallback logic. This is what this patch does.

The instance_init function of devices should always succeed to be able

{"return": {}}

This should not happen. Fix this problem by moving the affected code from

7388efafc2 target/ppc, spapr: Move VPA information to machine_data
CPUPPCState currently contains a number of fields containing the state of
the VPA.  The VPA is a PAPR specific concept covering several guest/host
shared memory areas used to communicate some information with the
hypervisor.

As a PAPR concept this is really machine specific information, although it
is per-cpu, so it doesn't really belong in the core CPU state structure.

There's also other information that's per-cpu, but platform/machine
specific.  So create a (void *)machine_data in PowerPCCPU which can be
used by the machine to locate per-cpu data.  Intialization, lifetime and
cleanup of machine_data is entirely up to the machine type.

9986ddec4c spapr_cpu_core: add missing rollback on realization path
The spapr_realize_vcpu() function doesn't rollback in case of error.
This isn't a problem with coldplugged CPUs because the machine won't
start and QEMU will exit. Hotplug is a different story though: the
CPU thread is started under object_property_set_bool() and it assumes
it can access the CPU object.

If icp_create() fails, we return an error without unregistering the
reset handler for this CPU, and we let the underlying QEMU thread for
this CPU alive. Since spapr_cpu_core_realize() doesn't care to unrealize
already realized CPUs either, but happily frees all of them anyway, the
CPU thread crashes instantly:

(qemu) device_add host-spapr-cpu-core,core-id=1,id=gku

27607c1cdc spapr_cpu_core: fix potential leak in spapr_cpu_core_realize()
Commit 94ad93bd97 (QEMU 2.12) switched to instantiate CPUs separately
but it missed to adapt the error path accordingly. If something fails in
the CPU creation loop, then the CPU object that was just created is leaked.

The error paths in this function are a bit obfuscated, and adding
yet another label to free this CPU object makes it worse. We should
move the block of the loop to a separate function, with a proper
rollback path, but this is a bigger cleanup.

For now, let's just fix the bug by adding the missing calls to
object_unref(). This will allow easier backport to older QEMU
versions.

Add support for multiple IOMMU indexes to the IOMMU notifier APIs.
When initializing a notifier with iommu_notifier_init(), the caller
must pass the IOMMU index that it is interested in. When a change
happens, the IOMMU implementation must pass
memory_region_notify_iommu() the IOMMU index that has changed and
that notifiers must be called for.

IOMMUs which support only a single index don't need to change.
Callers which only really support working with IOMMUs with a single
index can use the result of passing MEMTXATTRS_UNSPECIFIED to
memory_region_iommu_attrs_to_index().

acd9575e59 aspeed_scu: Implement RNG register
The ASPEED SoCs contain a single register that returns random data when
read. This models that register so that guests can use it.

The random number data register has a corresponding control register,
however it returns data regardless of the state of the enabled bit, so
the model follows this behaviour.

When the qcrypto call fails we exit as the guest uses the random number
device to feed it's entropy pool, which is used for cryptographic
purposes.

f81804a52b hw/core/or-irq: Support more than 16 inputs to an OR gate
For the IoTKit MPC support, we need to wire together the
interrupt outputs of 17 MPCs; this exceeds the current
value of MAX_OR_LINES. Increase MAX_OR_LINES to 32 (which
should be enough for anyone).

The tricky part is retaining the migration compatibility for
existing OR gates; we add a subsection which is only used
for larger OR gates, and define it such that we can freely
increase MAX_OR_LINES in future (or even move to a dynamically
allocated levels[] array without an upper size limit) without
breaking compatibility.

95f875654a arm: Don't crash if user tries to use a Cortex-M CPU without an NVIC
The Cortex-M CPU and its NVIC are two intimately intertwined parts of
the same hardware; it is not possible to use one without the other.
Unfortunately a lot of our board models don't do any sanity checking
on the CPU type the user asks for, so a command line like
    qemu-system-arm -M versatilepb -cpu cortex-m3
will create an M3 without an NVIC, and coredump immediately.
In the other direction, trying a non-M-profile CPU in an M-profile
board won't blow up, but doesn't do anything useful either:
    qemu-system-arm -M lm3s6965evb -cpu arm926

Add some checking in the NVIC and CPU realize functions that the
user isn't trying to use an NVIC without an M-profile CPU or
an M-profile CPU without an NVIC, so we can produce a helpful
error message rather than a core dump.

38d81dafb3 hw/arm/armv7m: Remove unused armv7m_init() function
Remove the now-unused armv7m_init() function. This was a legacy from
before we properly QOMified ARMv7M, and it has some flaws:

 * it combines work that needs to be done by an SoC object (creating
   and initializing the TYPE_ARMV7M object) with work that needs to
   be done by the board model (setting the system up to load the ELF
   file specified with -kernel)
 * TYPE_ARMV7M creation failure is fatal, but an SoC object wants to
   arrange to propagate the failure outward
 * it uses allocate-and-create via qdev_create() whereas the current
   preferred style for SoC objects is to do creation in-place

Board and SoC models can instead do the two jobs this function
was doing themselves, in the right places and with whatever their
preferred style/error handling is.

ppc patch queue 2018-06-12

Here's another batch of ppc patches towards the 3.0 release.  There's
a fair bit here, because I've been working through my mail backlog
after a holiday.  There's not much of a central theme, amongst other
things we have:
    * ppc440 / sam460ex improvements
    * logging and error cleanups
    * 40p (PReP) bugfixes
    * Macintosh fixes and cleanups
    * Add emulation of the new POWER9 store-forwarding barrier
      instruction variant
    * Hotplug cleanups

265b578c58 object: fix OBJ_PROP_LINK_UNREF_ON_RELEASE ambivalence
A link property can be set during creation, with
object_property_add_link() and later with object_property_set_link().

add_link() doesn't add a reference to the target object, while
set_link() does.

Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link,
says whether a reference must be released when the property is destroyed.
This can lead to leaks if the property was later set_link(), as the
added reference is never released.

Instead, rename OBJ_PROP_LINK_UNREF_ON_RELEASE to OBJ_PROP_LINK_STRONG
and use that has an indication on how the link handle reference
management in set_link().

30f79dc13f spapr_pci: Remove unhelpful pagesize warning
By default, the IOMMU model built into the spapr virtual PCI host bridge
supports 4kiB and 64kiB IOMMU page sizes.  However this can be overridden
which may be desirable to allow larger IOMMU page sizes when running a
guest with hugepage backing and passthrough devices.  For that reason a
warning was printed when the device wasn't configured to allow the pagesize
with which guest RAM is backed.

Experience has proven, however, that this message is more confusing than
useful.  Worse it sometimes makes little sense when the host-available page
sizes don't match those available on the guest, which can happen with
a POWER8 guest running on a POWER9 KVM host.

Long term we do want better handling to allow large IOMMU page sizes to be
used, but for now this parameter and warning don't really accomplish it.
So, remove the message, pending a better solution.

d638fd5c96 mos6522: move timer frequency initialisation to mos6522_reset
The 6522 VIA timer frequency cannot be set by altering registers within the
device itself and hence it is a fixed property of the machine.

Move the initialisation of the timer frequency to the mos6522 reset function
and ensure that any subclasses always call the parent reset function so that
it isn't required to store the timer frequency within vmstate_mos6522_timer
itself.

By moving the frequency initialisation to the device reset function then we
find that the realize function for both mos6522 and mos6522_cuda becomes
obsolete and can simply be removed.

2e3e5c7e92 cuda: embed mos6522_cuda device directly rather than using QOM object link
Examining the migration stream it can be seen that the mos6522 device state is
being stored separately rather than as part of the CUDA device which is
incorrect (and likely to cause issues if another mos6522 device is added to
the machine).

Resolve this by embedding the mos6522_cuda device directly within the CUDA
device rather than using a QOM object link to reference the device separately.

Note that we also bump the version in vmstate_cuda to reflect this change: this
isn't particularly important for the moment as the Mac machine migration isn't
100% reliable due to issues migrating the timebase under TCG.

VIO devices have an "irq" property that can be used by the sPAPR IRQ
allocator as an IRQ number hint. But it is not set in QEMU nor in

new static IRQ allocator we want to introduce in sPAPR.

Unfortunately this commit didn't do the same for the 40p machine which broke

875bad3135 40p: remove pci_allow_0_address = true from 40p machine class
The Linux sandalfoot zImage has an initialisation process which resets the
VGA controller by setting all the BAR addresses to zero to access the VGA
ioports at their legacy addresses.

Unfortunately setting the framebuffer BAR to address 0 makes the framebuffer
memory overlap the internal VGA memory causing accesses to fail, and so
prevents the kernel from switching successfully to text mode.

Since OpenHackWare configures the framebuffer BAR address outside of the legacy
VGA internal memory space, remove pci_allow_0_address from the 40p machine class
which causes the BAR reprogramming to zero to fail and so the VGA internal
memory can be accessed correctly again.
