For v7M, writes to the CONTROL register are only permitted for
privileged code. However even if the code is privileged, the
write must not affect the SPSEL bit in the CONTROL register
if the CPU is in Thread mode (as documented in the pseudocode
for the MSR instruction). Implement this, instead of permitting
SPSEL to be written in all cases.
This was causing mbed applications not to run, because the
RTX RTOS they use relies on this behaviour.

When running with KVM enabled, you can choose between emulating the
gic in kernel or user space. If the kernel supports in-kernel virtualization
of the interrupt controller, it will default to that. If not, if will
default to user space emulation.
Unfortunately when running in user mode gic emulation, we miss out on
interrupt events which are only available from kernel space, such as the timer.
This patch leverages the new kernel/user space pending line synchronization for
timer events. It does not handle PMU events yet.

When running KVM on POWER, we allow the user to pass "-cpu POWERx" instead
of "-cpu host". This is achieved by patching the ppc_cpu_aliases[] array
so that "POWERx" points to the CPU class with the same PVR as the host CPU.
This causes CPUs to be instantiated from this CPU class instead of the
TYPE_HOST_POWERPC_CPU class which is used with "-cpu host". These CPUs thus
miss all the KVM specific tuning from kvmppc_host_cpu_class_init().
This currently causes QEMU with "-cpu POWER9" to fail when running KVM on a
POWER9 DD1 host:
qemu-system-ppc64: Register sync failed... If you're using kvm-hv.ko, only
"-cpu host" is possible
kvm_init_vcpu failed: Invalid argument
Let's have the "POWERx" alias to point to TYPE_HOST_POWERPC_CPU directly,
so that "-cpu POWERx" instantiates CPUs from the same class as "-cpu host".

We print a warning if the spapr IOMMU isn't configured to support a page
size matching the host page size backing RAM. When that's the case we need
more complex logic to translate VFIO mappings, which is slower.
But, it's not so slow that it would be at all noticeable against the
general slowness of TCG. So, only warn when using KVM. This removes some
noisy and unhelpful warnings from make check on hosts with page sizes
which typically differ from those on POWER (e.g. Sparc).

In target/ppc/mmu-hash64.c there already exists the function
ppc_hash64_get_phys_page_debug() to get the physical (real) address for
a given effective address in hash mode.
Implement the function ppc_radix64_get_phys_page_debug() to allow a real
address to be obtained for a given effective address in radix mode.
This is used when a debugger is attached to qemu.
Previously we just had a comment saying this is unimplemented which then
fell through to the default case and caused an abort due to
unrecognised mmu model as the default had no case for the V3 mmu, which
was misleading at best.
We reuse ppc_radix64_walk_tree() which is used by the radix fault
handler since the process of walking the radix tree is identical.

The mmu-radix64.c file implements functions to enable the radix mmu
emulation in tcg mode. There is a function ppc_radix64_walk_tree() which
performs the radix tree walk and also implicitly checks the pte
protection.
Move the protection checking of the pte from the ppc_radix64_walk_tree()
function into the caller. This means the ppc_radix64_walk_tree() function
can be used without protection checking which is useful for debugging.
ppc_radix64_walk_tree() no longer needs to take the rwx and prot variables.

AIUI, ->unplug_request in the HotplugHandler is used for "soft"
unplug, where acknowledgement from the guest is required before
completing the unplug, whereas ->unplug is used for "hard" unplug
where qemu unilaterally removes the device, and the guest just has to
cope with its sudden absence. For spapr we (correctly) use
->unplug_request for CPU and memory hot unplug but we use ->unplug for
PCI.
While I think it might be possible to support "hard" PCI unplug within
the PAPR model, that's not how it actually works now. Although it's
called from ->unplug, the PCI unplug path will usually just mark the
device for removal, with completion of the unplug delayed until
userspace responds to the unplug notification. If the guest doesn't
respond as expected, that could delay the unplug completion arbitrarily
long.
To reflect that, change the PCI unplug path to be called from
->unplug_request. We also rename spapr_phb_hot_plug_child() and
spapr_phb_hot_unplug_child() to spapr_pci_plug() and
spapr_pci_unplug_request() to more obviously reflect the callbacks they're
implementing.

spapr_drc_attach() has a 'coldplug' parameter which sets the DRC into
configured state initially, instead of the usual ISOLATED/UNUSABLE state.
It turns out this is unnecessary: although coldplugged devices do need to
be in CONFIGURED state once the guest starts, that will already be
accomplished by the reset code which will move DRCs for already plugged
devices into a coldplug equivalent state.

At the moment, spapr_drc_release() has an ugly switch on the DRC type to
call the right, device-specific release function. This cleans it up by
doing that via a proper QOM method.
It's still arguably an abstraction violation for the DRC code to call into
the specific device code, but one mess at a time.

DRC objects have a regular device reset method. However, it only gets
called in the usual way for PCI DRCs. Because of where CPU and LMB DRCs
are in the QOM tree, their device reset method isn't automatically called.
So, the machine manually registers reset handlers to call device_reset().
This patch removes the device reset method, and instead always explicitly
registers the reset handler from realize(). This means the callers don't
have to worry about the two cases, and we always get proper resets.

The DR-indicator is essentially a "virtual LED" attached to a hotpluggable
device, which the guest can set to various states for the attention of
the operator or management layers.
It's mostly guest managed, except that we once-off set it to
ACTIVE/INACTIVE in the attach/detach path. While that makes certain sense,
there's no indication in PAPR that the hypervisor should do this, and the
drmgr code on the guest side doesn't appear to need it (it will already set
the indicator to ACTIVE on hotplug, and INACTIVE on remove).
So, leave the DR-indicator entirely to the guest; the only thing we need
to do is ensure it's in a sane state on reset.

Properly set the book E exception syndrome register when a floating
point exception occurs.
Currently on a book E processor, the POWERPC_EXCP_FP exception handler
fails to set "env->spr[SPR_BOOKE_ESR] = ESR_FP;" as required by the
book E specification.

since commit 5c4537bd ("spapr: Fix 2.7<->2.8 migration of PCI host bridge"),
some migration fields are forged from the new ones in spapr_pci_pre_save().
It works well, except when the number of MSI devices is 0,
because in this case the function exits immediately.
This fix moves the migration code before the exit code.
The problem can be reproduced with these commands:
source qemu-2.9:
qemu-system-ppc64 -monitor stdio -M pseries-2.6 -nodefaults -S
destination qemu-2.6:
qemu-system-ppc64 -monitor stdio -M pseries-2.6 -nodefaults \
-incoming tcp:0:4444
on the source:
migrate tcp:localhost:4444
Destination fails with the following error:
qemu-system-ppc64: error while loading state for
instance 0x0 of device 'spapr_pci'
qemu-system-ppc64: load of migration failed: Invalid argument

object init earlier, along with the global properties, right after

Intel 82599 VFs report a PCIe capability version of 0, which is
invalid. The earliest version of the PCIe spec used version 1. This
causes Windows to fail startup on the device and it will be disabled
with error code 10. Our choices are either to drop the PCIe cap on
such devices, which has the side effect of likely preventing the guest
from discovering any extended capabilities, or performing a fixup to
update the capability to the earliest valid version. This implements
the latter.

VFIOGroup.device_list is effectively our reference tracking mechanism
such that we can teardown a group when all of the device references
are removed. However, we also use this list from our machine reset
handler for processing resets that affect multiple devices. Generally
device removals are fully processed (exitfn + finalize) when this
reset handler is invoked, however if the removal is triggered via
another reset handler (piix4_reset->acpi_pcihp_reset) then the device
exitfn may run, but not finalize. In this case we hit asserts when
we start trying to access PCI helpers since much of the PCI state of
the device is released. To resolve this, add a pointer to the Object
DeviceState in our common base-device and skip non-realized devices
as we iterate.

Let NBD use the trace mechanisms already present in qemu. Now you can
use the -trace optino of qemu, or the -T/--trace option of qemu-img,
qemu-io, and qemu-nbd, to select nbd traces. For qemu, the QMP commands
trace-event-{get,set}-state can also toggle tracing on the fly.
Example:
qemu-nbd --trace 'nbd_*' <image file> # enables all nbd traces
Recompilation with CFLAGS=-DDEBUG_NBD is no more needed, furthermore,
DEBUG_NBD macro is removed from the code.
