When the VM is stopped, the VM state handler stabilizes the XIVE IC
and marks the EQ pages dirty. These are then transferred to destination
before the transfer of the device vmstates starts.
The SpaprXive interrupt controller model captures the XIVE internal
tables, EAT and ENDT and the XiveTCTX model does the same for the
thread interrupt context registers.
At restart, the SpaprXive 'post_load' method restores all the XIVE
states. It is called by the sPAPR machine 'post_load' method, when all
XIVE states have been transferred and loaded.
Finally, the source states are restored in the VM change state handler
when the machine reaches the running state.

This handler is in charge of stabilizing the flow of event notifications
in the XIVE controller before migrating a guest. This is a requirement
before transferring the guest EQ pages to a destination.
When the VM is stopped, the handler sets the source PQs to PENDING to
stop the flow of events and to possibly catch a triggered interrupt
occuring while the VM is stopped. Their previous state is saved. The
XIVE controller is then synced through KVM to flush any in-flight
event notification and to stabilize the EQs. At this stage, the EQ
pages are marked dirty to make sure the EQ pages are transferred if a
migration sequence is in progress.
The previous configuration of the sources is restored when the VM
resumes, after a migration or a stop. If an interrupt was queued while
the VM was stopped, the handler simply generates the missing trigger.

This extends the KVM XIVE device backend with 'synchronize_state'
methods used to retrieve the state from KVM. The HW state of the
sources, the KVM device and the thread interrupt contexts are
collected for the monitor usage and also migration.
These get operations rely on their KVM counterpart in the host kernel
which acts as a proxy for OPAL, the host firmware. The set operations
will be added for migration support later.

XIVE hcalls are all redirected to QEMU as none are on a fast path.
When necessary, QEMU invokes KVM through specific ioctls to perform
host operations. QEMU should have done the necessary checks before
calling KVM and, in case of failure, H_HARDWARE is simply returned.
H_INT_ESB is a special case that could have been handled under KVM
but the impact on performance was low when under QEMU. Here are some
figures :

This introduces a set of helpers when KVM is in use, which create the
KVM XIVE device, initialize the interrupt sources at a KVM level and
connect the interrupt presenters to the vCPU.
They also handle the initialization of the TIMA and the source ESB
memory regions of the controller. These have a different type under
KVM. They are 'ram device' memory mappings, similarly to VFIO, exposed
to the guest and the associated VMAs on the host are populated
dynamically with the appropriate pages using a fault handler.

When we added support for NVLink2 passthrough devices, we changed the

However, because of the delay between when the patch was posted and when
it was merged, we ended up with that compatibility hook applying for
machine versions 3.1 and earlier whereas it should apply for 4.0 and
earlier (since the patch was applied early in the 4.1 tree).

The processor stop status and control register (PSSCR) is used to
control the power saving facilities of the thread. The exit criterion
bit (EC) is used to specify whether the thread should be woken by any
interrupt (EC == 0) or only an interrupt enabled in the LPCR to wake the
thread (EC == 1).
The rtas facilities start-cpu and self-stop are used to transition a
vcpu between the stopped and running states. When a vcpu is stopped it
may only be started again by the start-cpu rtas call.
Currently a vcpu in the stopped state will start again whenever an
interrupt comes along due to PSSCR_EC being cleared, and while this is
architecturally correct for a hardware thread, a vcpu is expected to
only be woken by calling start-cpu. This means when performing a reboot
on a tcg machine that the secondary threads will restart while the
primary is still in slof, this is unsupported and causes call traces

If a machine is started with ic-mode=xive but the guest only knows
about XICS, eg. an RHEL 7.6 guest, the kernel panics. This is
expected but a bit unfortunate since the crash doesn't provide
much information for the end user to guess what's happening.
Detect that during CAS and exit QEMU with a proper error message
instead, like it is already done for the MMU.
Even if this is less likely to happen, the opposite case of a guest
that only knows about XIVE would certainly fail all the same if the
machine is started with ic-mode=xics.
Also, the only valid values a guest can pass in byte 23 of OV5 during
CAS are 0b00 (XIVE legacy mode) and 0b01 (XIVE exploitation mode). Any
other value is a bug, at least with the current spec. Again, it does
not seem right to let the guest go on without a precise idea of the
interrupt mode it asked for.
Handle these cases as well.

The high order bits of the address of the OS event queue is stored in
bits [4-31] of word2 of the XIVE END internal structures and the low
order bits in word3. This structure is using Big Endian ordering and
computing the value requires some simple arithmetic which happens to
be wrong. The mask removing bits [0-3] of word2 is applied to the
wrong value and the resulting address is bogus when above 64GB.
Guests with more than 64GB of RAM will allocate pages for the OS event
queues which will reside above the 64GB limit. In this case, the XIVE
device model will wake up the CPUs in case of a notification, such as
IPIs, but the update of the event queue will be written at the wrong
place in memory. The result is uncertain as the guest memory is
trashed and IPI are not delivered.

This tag contains a handful of patches that I'd like to target for 4.1:
* An emulation for SiFive's GPIO device.
* A fix to disallow sfence.vma from userspace.
* Additional decodetree cleanups that should have no functional impact.
* C extension emulation fidelity fixes that were noticed as part of that
cleanup process.
* A new "spike" target, along with the deprecation of a handful of old
targets and CPUs.
* Some initial infastructure related to the hypervisor extension.
* An emulation fidelity fix that prevents prevents arbitrary bits in the
SIP CSR from being set.
* A small performance improvement that avoids excessive TLB flushing
when the ASID does not change.
This time I've used a new testing workflow: I've tested on both 32-bit
and 64-bit builds of OpenEmbedded, via the default OpenSBI-based boot
flow.

This attempts to clean-up the output to better match the output of the
rest of the QEMU check system when called with -makecheck. This includes:
- formatting as " TEST iotest-FMT: nnn"
- only dumping config on failure (when -makecheck enabled)
The non-make check output has been cleaned up as well:
- line re-displayed (\r) at the end
- fancy colours for pass/fail/skip
- timestamps always printed (option removed)

Currently, all tests are in the "auto" group. This is a little bit pointless.
OTOH, we need a group for the tests that we can automatically run during
"make check" each time, too. Tests in this new group are supposed to run
with every possible QEMU configuration, for example they must run with every
QEMU binary (also non-x86), without failing when an optional features is
missing (but reporting "skip" is ok), and be able to run on all kind of host
filesystems and users (i.e. also as "nobody" or "root").
So let's use the "auto" group for this class of tests now. The initial
list has been determined by running the iotests with non-x86 QEMU targets
and with our CI pipelines on Gitlab, Cirrus-CI and Travis (i.e. including
macOS and FreeBSD).

This provides the bootstrap and low level helper functions for an

the emulation. semihosting's parameter passing is a little funky so we
end up using the stack and pointing to that as the parameter block.

We can certainly support some common tests for system emulation that
