Xen unstable (to be in 4.11) has two new dmops, relocate_memory and
pin_memory_cacheattr. Use these to set up the VGA memory, replacing the
previous calls to libxc. This allows the VGA console to work properly
when QEMU is running restricted (-xen-domid-restrict).
Wrapper functions are provided to allow QEMU to work with older versions
of Xen.
Tweak the error handling while making this change:
* Report pin_memory_cacheattr errors.
* Report errors even when DEBUG_HVM is not set. This is useful for
trying to understand why VGA is not working, since otherwise it just
fails silently.
* Fix the return values when an error occurs. The functions now
consistently return -1 and set errno.

Drop individual use of xendevicemodel_restrict and

In icount mode, instructions that access io memory spaces in the middle
of the translation block invoke TB recompilation. After recompilation,
such instructions become last in the TB and are allowed to access io
memory spaces.
When the code includes instruction like i386 'xchg eax, 0xffffd080'
which accesses APIC, QEMU goes into an infinite loop of the recompilation.
This instruction includes two memory accesses - one read and one write.
After the first access, APIC calls cpu_report_tpr_access, which restores
the CPU state to get the current eip. But cpu_restore_state_from_tb
resets the cpu->can_do_io flag which makes the second memory access invalid.
Therefore the second memory access causes a recompilation of the block.
Then these operations repeat again and again.
This patch moves resetting cpu->can_do_io flag from
cpu_restore_state_from_tb to cpu_loop_exit* functions.
It also adds a parameter for cpu_restore_state which controls restoring
icount. There is no need to restore icount when we only query CPU state
without breaking the TB. Restoring it in such cases leads to the
incorrect flow of the virtual time.
In most cases new parameter is true (icount should be recalculated).
But there are two cases in i386 and openrisc when the CPU state is only
queried without the need to break the TB. This patch fixes both of
these cases.

Out-Of-Band is currently only for QMP, and non-MUX chardev backends.

qemu_aio_coroutine_enter() is (indirectly) called recursively when
processing co_queue_wakeup. This can lead to stack exhaustion.
This patch rewrites co_queue_wakeup in an iterative fashion (instead of
recursive) with bounded memory usage to prevent stack exhaustion.
qemu_co_queue_run_restart() is inlined into qemu_aio_coroutine_enter()
and the qemu_coroutine_enter() call is turned into a loop to avoid
recursion.
There is one change that is worth mentioning: Previously, when
coroutine A queued coroutine B, qemu_co_queue_run_restart() entered
coroutine B from coroutine A. If A was terminating then it would still
stay alive until B yielded. After this patch B is entered by A's parent
so that a A can be deleted immediately if it is terminating.
It is safe to make this change since B could never interact with A if it
was terminating anyway.

If the backend could not transmit a packet right away for some reason,
the packet is queued for asynchronous sending. The corresponding vq
element is tracked in the async_tx.elem field of the VirtIONetQueue,
for later freeing when the transmission is complete.
If a reset happens before completion, virtio_net_tx_complete() will push
async_tx.elem back to the guest anyway, and we end up with the inuse flag
of the vq being equal to -1. The next call to virtqueue_pop() is then
likely to fail with "Virtqueue size exceeded".
This can be reproduced easily by starting a guest with an hubport backend
that is not connected to a functional network, eg,
-device virtio-net-pci,netdev=hub0 -netdev hubport,id=hub0,hubid=0
and no other -netdev hubport,hubid=0 on the command line.
The appropriate fix is to ensure that such an asynchronous transmission
cannot survive a device reset. So for all queues, we first try to send
the packet again, and eventually we purge it if the backend still could
not deliver it.

Linux does not detect a break from this IMX serial driver as a magic
sysrq. Nor does it note a break in the port error counts.
The former is because the Linux driver uses the BRCD bit in the USR2
register to trigger the RS-232 break handler in the kernel, which is
where sysrq hooks in. The emulated UART was not setting this status
bit.
The latter is because the Linux driver expects, in addition to the BRK
bit, that the ERR bit is set when a break is read in the FIFO. A break
should also count as a frame error, so add that bit too.

The "control" key is introduced to store this extra flag. "control"

rather than command specific arguments. Let "run-oob" be the first.

The "oob" idea is proposed by Markus Armbruster in following thread:
https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg02057.html
This new "allow-oob" boolean will be exposed by "query-qmp-schema" as
well for command entries, so that QMP clients can know which commands
can be used in out-of-band calls. For example the command "migrate"
originally looks like:
{"name": "migrate", "ret-type": "17", "meta-type": "command",
"arg-type": "86"}
And it'll be changed into:
{"name": "migrate", "ret-type": "17", "allow-oob": false,
"meta-type": "command", "arg-type": "86"}
This patch only provides the QMP interface level changes. It does not

The macro uses lower-case letters because:
1. There does not seem to be a hard rule on whether qemu macros have to
be upper-cased,
2. The current situation in qapi/qmp is inconsistent (compare e.g.
QINCREF() vs. qdict_put()),
3. qobject_to() will evaluate its @obj parameter only once, thus it is
generally not important to the caller whether it is a macro or not,
4. I prefer it aesthetically.
The macro parameter order is chosen with typename first for

for legibility (read it as "qobject to" type "applied to" obj).

#define FSL_IMX6_ENET_MAC_IRQ 119
According to https://www.nxp.com/docs/en/reference-manual/IMX6DQRM.pdf,
page 225, in Table 3-1. ARM Cortex A9 domain interrupt summary,
interrupts are as follows.
150 ENET MAC 0 IRQ
151 ENET MAC 0 1588 Timer interrupt
where
150 - 32 == 118
151 - 32 == 119
In other words, the vector definitions in the fsl-imx6.h file are reversed.
Fixing the interrupts alone causes problems with older Linux kernels:
The Ethernet interface will fail to probe with Linux v4.9 and earlier.
Linux v4.1 and earlier will crash due to a bug in Ethernet driver probe
error handling. This is a Linux kernel problem, not a qemu problem:
the Linux kernel only worked by accident since it requested both interrupts.
For backward compatibility, generate the Ethernet interrupt on both interrupt
lines. This was shown to work from all Linux kernel releases starting with
v3.16.

With all targets defining CPU_RESOLVING_TYPE, refactor
cpu_parse_cpu_model(type, cpu_model) to parse_cpu_model(cpu_model)
so that callers won't have to know internal resolving cpu
type. Place it in exec.c so it could be called from both
target independed vl.c and *-user/main.c.
That allows us to stop abusing cpu type from
MachineClass::default_cpu_type
as resolver class in vl.c which were confusing part of
cpu_parse_cpu_model().
Also with new parse_cpu_model(), the last users of cpu_init()
in null-machine.c and bsd/linux-user targets could be switched
to cpu_create() API and cpu_init() API will be removed by
follow up patch.
With no longer users left remove MachineState::cpu_model field,
new code should use MachineState::cpu_type instead and
leave cpu_model parsing to generic code in vl.c.

When doing drive mirror to a low speed shared storage, if there was heavy
BLK IO write workload in VM after the 'ready' event, drive mirror block job
can't be canceled immediately, it would keep running until the heavy BLK IO
workload stopped in the VM.
Libvirt depends on the current block-job-cancel semantics, which is that
when used without a flag after the 'ready' event, the command blocks
until data is in sync. However, these semantics are awkward in other
situations, for example, people may use drive mirror for realtime
backups while still wanting to use block live migration. Libvirt cannot
start a block live migration while another drive mirror is in progress,
but the user would rather abandon the backup attempt as broken and
proceed with the live migration than be stuck waiting for the current
drive mirror backup to finish.
The drive-mirror command already includes a 'force' flag, which libvirt
does not use, although it documented the flag as only being useful to
quit a job which is paused. However, since quitting a paused job has
the same effect as abandoning a backup in a non-paused job (namely, the
destination file is not in sync, and the command completes immediately),
we can just improve the documentation to make the force flag obviously
useful.

Instead of automatically transitioning from PENDING to CONCLUDED, gate
the .prepare() and .commit() phases behind an explicit acknowledgement
provided by the QMP monitor if auto_finalize = false has been requested.
This allows us to perform graph changes in prepare and/or commit so that
graph changes do not occur autonomously without knowledge of the
controlling management layer.
Transactions that have reached the "PENDING" state together can all be
moved to invoke their finalization methods by issuing block_job_finalize
to any one job in the transaction.
Jobs in a transaction with mixed job->auto_finalize settings will all
remain stuck in the "PENDING" state, as if the entire transaction was
specified with auto_finalize = false. Jobs that specified
auto_finalize = true, however, will still not emit the PENDING event.

For jobs utilizing the new manual workflow, we intend to prohibit
them from modifying the block graph until the management layer provides
an explicit ACK via block-job-finalize to move the process forward.
To distinguish this runstate from "ready" or "waiting," we add a new
"pending" event and status.
For now, the transition from PENDING to CONCLUDED/ABORTING is automatic,
but a future commit will add the explicit block-job-finalize step.
Transitions:
Waiting -> Pending: Normal transition.
Pending -> Concluded: Normal transition.
Pending -> Aborting: Late transactional failures and cancellations.
Removed Transitions:
Waiting -> Concluded: Jobs must go to PENDING first.
Verbs:
Cancel: Can be applied to a pending job.

Some jobs upon finalization may need to perform some work that can
still fail. If these jobs are part of a transaction, it's important
that these callbacks fail the entire transaction.
We allow for a new callback in addition to commit/abort/clean that
allows us the opportunity to have fairly late-breaking failures
in the transactional process.
The expected flow is:
- All jobs in a transaction converge to the PENDING state,
added in a forthcoming commit.
- Upon being finalized, either automatically or explicitly
by the user, jobs prepare to complete.
- If any job fails preparation, all jobs call .abort.
- Otherwise, they succeed and call .commit.

For jobs that have reached their CONCLUDED state, prior to having their
last reference put down (meaning jobs that have completed successfully,
unsuccessfully, or have been canceled), allow the user to dismiss the
job's lingering status report via block-job-dismiss.
This gives management APIs the chance to conclusively determine if a job
failed or succeeded, even if the event broadcast was missed.
Note: block_job_do_dismiss and block_job_decommission happen to do
exactly the same thing, but they're called from different semantic
contexts, so both aliases are kept to improve readability.
Note 2: Don't worry about the 0x04 flag definition for AUTO_DISMISS, she
has a friend coming in a future patch to fill the hole where 0x02 is.

Which commands ("verbs") are appropriate for jobs in which state is
also somewhat burdensome to keep track of.
As of this commit, it looks rather useless, but begins to look more
interesting the more states we add to the STM table.
A recurring theme is that no verb will apply to an 'undefined' job.
Further, it's not presently possible to restrict the "pause" or "resume"
verbs any more than they are in this commit because of the asynchronous
nature of how jobs enter the PAUSED state; justifications for some
seemingly erroneous applications are given below.
=====
Verbs
=====
Cancel: Any state except undefined.
Pause: Any state except undefined;
'created': Requests that the job pauses as it starts.
'running': Normal usage. (PAUSED)
'paused': The job may be paused for internal reasons,
but the user may wish to force an indefinite
user-pause, so this is allowed.
'ready': Normal usage. (STANDBY)
'standby': Same logic as above.
Resume: Any state except undefined;
'created': Will lift a user's pause-on-start request.
'running': Will lift a pause request before it takes effect.
'paused': Normal usage.
'ready': Will lift a pause request before it takes effect.
'standby': Normal usage.
Set-speed: Any state except undefined, though ready may not be meaningful.
Complete: Only a 'ready' job may accept a complete request.
=======
Changes
=======
(1)
To facilitate "nice" error checking, all five major block-job verb
interfaces in blockjob.c now support an errp parameter:
- block_job_user_cancel is added as a new interface.
- block_job_user_pause gains an errp paramter
- block_job_user_resume gains an errp parameter
- block_job_set_speed already had an errp parameter.
- block_job_complete already had an errp parameter.
(2)
block-job-pause and block-job-resume will no longer no-op when trying
to pause an already paused job, or trying to resume a job that isn't
paused. These functions will now report that they did not perform the
action requested because it was not possible.
iotests have been adjusted to address this new behavior.
(3)
block-job-complete doesn't worry about checking !block_job_started,
because the permission table guards against this.
(4)
test-bdrv-drain's job implementation needs to announce that it is
'ready' now, in order to be completed.

We're about to add several new states, and booleans are becoming
unwieldly and difficult to reason about. It would help to have a
more explicit bookkeeping of the state of blockjobs. To this end,
add a new "status" field and add our existing states in a redundant
manner alongside the bools they are replacing:
UNDEFINED: Placeholder, default state. Not currently visible to QMP
unless changes occur in the future to allow creating jobs
without starting them via QMP.
CREATED: replaces !!job->co && paused && !busy
RUNNING: replaces effectively (!paused && busy)
PAUSED: Nearly redundant with info->paused, which shows pause_count.
This reports the actual status of the job, which almost always
matches the paused request status. It differs in that it is
strictly only true when the job has actually gone dormant.
READY: replaces job->ready.
STANDBY: Paused, but job->ready is true.
New state additions in coming commits will not be quite so redundant:
WAITING: Waiting on transaction. This job has finished all the work
it can until the transaction converges, fails, or is canceled.
PENDING: Pending authorization from user. This job has finished all the
work it can until the job or transaction is finalized via
block_job_finalize. This implies the transaction has converged
and left the WAITING phase.
ABORTING: Job has encountered an error condition and is in the process
of aborting.
CONCLUDED: Job has ceased all operations and has a return code available
for query and may be dismissed via block_job_dismiss.
NULL: Job has been dismissed and (should) be destroyed. Should never
be visible to QMP.
Some of these states appear somewhat superfluous, but it helps define the
expected flow of a job; so some of the states wind up being synchronous
empty transitions. Importantly, jobs can be in only one of these states
at any given time, which helps code and external users alike reason about
the current condition of a job unambiguously.

model all independent jobs as single job transactions.
It's one less case we have to worry about when we add more states to the
transition machine. This way, we can just treat all job lifetimes exactly
the same. This helps tighten assertions of the STM graph and removes some
conditionals that would have been needed in the coming commits adding a
more explicit job lifetime management API.

The global hack for creating SCSI devices has recently been removed,
but this apparently broke SCSI devices on some boards that were not
ready for this change yet. For the 40p machine you now get:
$ ppc64-softmmu/qemu-system-ppc64 -M 40p -cdrom x.iso
qemu-system-ppc64: -cdrom x.iso: machine type does not support if=scsi,bus=0,unit=2
Fix it by providing a lsi53c810_create() function that takes care
of calling scsi_bus_legacy_handle_cmdline() after creating the
corresponding SCSI controller.

there is no point to read fields here but not actually
checking them so drop it and read only header + dsdt/facs
addresses since it's needed later to fetch that tables.
With this cleanup we can get rid of AcpiFadtDescriptorRev3/
ACPI_FADT_COMMON_DEF which have no users left.

move FADT data initialization out of fadt_setup() into dedicated
init_fadt_data() that will set common for pc/q35 values in
AcpiFadtData structure and acpi_get_pm_info() will complement
it with pc/q35 specific values initialization.
That will allow to get rid of fadt_setup() and generalize
build_fadt() so it could be easily extended for rev5 and
reused by ARM target.
While at it also move facs/dsdt/xdsdt offsets from build_fadt()
arg list into AcpiFadtData, as they belong to the same dataset.

Although linkspeed and duplex can be set in a linux guest via 'ethtool -s',
this requires custom ethtool commands for virtio-net by default.
Introduce a new feature flag, VIRTIO_NET_F_SPEED_DUPLEX, which allows
the hypervisor to export a linkspeed and duplex setting. The user can
subsequently overwrite it later if desired via: 'ethtool -s'.
Linkspeed and duplex settings can be set as:
'-device virtio-net,speed=10000,duplex=full'
where speed is [0...INT_MAX], and duplex is ["half"|"full"].

Postcopy migration of dirty bitmaps. Only named dirty bitmaps are migrated.
If destination qemu is already containing a dirty bitmap with the same name
as a migrated bitmap (for the same node), then, if their granularities are
the same the migration will be done, otherwise the error will be generated.
If destination qemu doesn't contain such bitmap it will be created.

At the moment we unconditionally avoid mapping MSIX data of a BAR and
emulate MSIX table in QEMU. However it is 1) not always necessary as
a platform may provide a paravirt interface for MSIX configuration;
2) can affect the speed of MMIO access by emulating them in QEMU when
frequently accessed registers share same system page with MSIX data,
this is particularly a problem for systems with the page size bigger
than 4KB.
A new capability - VFIO_REGION_INFO_CAP_MSIX_MAPPABLE - has been added
to the kernel [1] which tells the userspace that mapping of the MSIX data
is possible now. This makes use of it so from now on QEMU tries mapping
the entire BAR as a whole and emulate MSIX on top of that.

This patch allows to unbind devices from QemuConsoles, using the new
graphic_console_close() function. The QemuConsole will show a static
display then, saying the device was unplugged. When re-plugging a
display later on the QemuConsole will be reused.
Eventually we will allocate and release QemuConsoles dynamically at some
point in the future, that'll need more infrastructure though to notify
user interfaces (gtk, sdl, spice, ...) about QemuConsoles coming and
going.
