f0175135e7 hw/intc/arm_gicv3_its: Factor out "find ITE given devid, eventid"
The operation of finding an interrupt table entry given a (DeviceID,
EventID) pair is necessary in multiple different ITS commands.  The
process requires first using the DeviceID as an index into the device
table to find the DTE, and then useng the EventID as an index into
the interrupt table specified by that DTE to find the ITE.  We also
need to handle all the possible error cases: indexes out of range,
table memory not readable, table entries not valid.

Factor this out into a separate lookup_ite() function which we
can then call from the places where we were previously open-coding
this sequence. We'll also need this for some of the new GICv4.0
commands.

93f4fdcd4d hw/intc/arm_gicv3_its: Distinguish success and error cases of CMD_CONTINUE
In the ItsCmdResult enum, we currently distinguish only CMD_STALL
(failure, stall processing of the command queue) and CMD_CONTINUE
(keep processing the queue), and we use the latter both for "there
was a parameter error, go on to the next command" and "the command
succeeded, go on to the next command".  Sometimes we would like to
distinguish those two cases, so add CMD_CONTINUE_OK to the enum to
represent the success situation, and use it in the relevant places.

0cdf7a5dc8 hw/intc/arm_gicv3_its: Implement VMAPP
Implement the GICv4 VMAPP command, which writes an entry to the vPE
table.

For GICv4.1 this command has extra fields in the command packet
and additional behaviour. We define the 4.1-only fields with the
FIELD macro, but only implement the GICv4.0 version of the command.

9de53de60c hw/intc/arm_gicv3_its: Implement VMAPI and VMAPTI
Implement the GICv4 VMAPI and VMAPTI commands. These write
an interrupt translation table entry that maps (DeviceID,EventID)
to (vPEID,vINTID,doorbell). The only difference between VMAPI
and VMAPTI is that VMAPI assumes vINTID == EventID rather than
both being specified in the command packet.

(This code won't be reachable until we allow the GIC version to be
set to 4.  Support for reading this new virtual-interrupt DTE and
handling it correctly will be implemented in a later commit.)

50d84584d3 hw/intc/arm_gicv3_its: Implement GITS_BASER2 for GICv4
The GICv4 defines a new in-guest-memory table for the ITS: this is
the vPE table.  Implement the new GITS_BASER2 register which the
guest uses to tell the ITS where the vPE table is located, including
the decode of the register fields into the TableDesc structure which
we do for the GITS_BASER<n> when the guest enables the ITS.

We guard provision of the new register with the its_feature_virtual()
function, which does a check of the GITS_TYPER.Virtual bit which
indicates presence of ITS support for virtual LPIs.  Since this bit
is currently always zero, GICv4-specific features will not be
accessible to the guest yet.

9acd2d3373 target/arm/cpu.c: ignore VIRQ and VFIQ if no EL2
In a GICv3, it is impossible for the GIC to deliver a VIRQ or VFIQ to
the CPU unless the CPU has EL2, because VIRQ and VFIQ are only
configurable via EL2-only system registers.  Moreover, in our
implementation we were only calculating and updating the state of the
VIRQ and VFIQ lines in gicv3_cpuif_virt_irq_fiq_update() when those
EL2 system registers changed.  We were therefore able to assert in
arm_cpu_set_irq() that we didn't see a VIRQ or VFIQ line update if
EL2 wasn't present.

This assumption no longer holds with GICv4:
 * even if the CPU does not have EL2 the guest is able to cause the
   GIC to deliver a virtual LPI by programming the ITS (which is a
   silly thing for it to do, but possible)
 * because we now need to recalculate the state of the VIRQ and VFIQ
   lines in more cases than just "some EL2 GIC sysreg was written",
   we will see calls to arm_cpu_set_irq() for "VIRQ is 0, VFIQ is 0"
   even if the guest is not using the virtual LPI parts of the ITS

Remove the assertions, and instead simply ignore the state of the
VIRQ and VFIQ lines if the CPU does not have EL2.

50a3a309e1 hw/intc/arm_gicv3: Report correct PIDR0 values for ID registers
We use the common function gicv3_idreg() to supply the CoreSight ID
register values for the GICv3 for the copies of these ID registers in
the distributor, redistributor and ITS register frames.  This isn't
quite correct, because while most of the register values are the
same, the PIDR0 value should vary to indicate which of these three
frames it is.  (You can see this and also the correct values of these
PIDR0 registers by looking at the GIC-600 or GIC-700 TRMs, for
example.)

Make gicv3_idreg() take an extra argument for the PIDR0 value.

671927a116 hw/intc/arm_gicv3: Insist that redist region capacity matches CPU count
Boards using the GICv3 need to configure it with both the total
number of CPUs and also the sizes of all the memory regions which
contain redistributors (one redistributor per CPU).  At the moment
the GICv3 checks that the number of CPUs specified is not too many to
fit in the defined redistributor regions, but in fact the code
assumes that the two match exactly.  For instance when we set the
GICR_TYPER.Last bit on the final redistributor in each region, we
assume that we don't need to consider the possibility of a region
being only half full of redistributors or even completely empty.  We
also assume in gicv3_redist_read() and gicv3_redist_write() that we
can calculate the CPU index from the offset within the MemoryRegion
and that this will always be in range.

Fortunately all the board code sets the redistributor region sizes to
exactly match the CPU count, so this isn't a visible bug.  We could
in theory make the GIC code handle non-full redistributor regions, or
have it automatically reduce the provided region sizes to match the
CPU count, but the simplest thing is just to strengthen the error
check and insist that the CPU count and redistributor region size
settings match exactly, since all the board code does that anyway.

552de79bfd migration: Read state once
The 'status' field for the migration is updated normally using
an atomic operation from the migration thread.
Most readers of it aren't that careful, and in most cases it doesn't
matter.

In query_migrate->fill_source_migration_info the 'state'
is read twice; the first time to decide which state fields to fill in,
and then secondly to copy the state to the status field; that can end up
with a status that's inconsistent; e.g. setting up the fields
for 'setup' and then having an 'active' status.  In that case
libvirt gets upset by the lack of ram info.
The symptom is:
   libvirt.libvirtError: internal error: migration was active, but no RAM info was set

Read the state exactly once in fill_source_migration_info.

This is a possible fix for:

08401c0426 migration: Allow migrate-recover to run multiple times
Previously migration didn't have an easy way to cleanup the listening
transport, migrate recovery only allows to execute once.  That's done with a
trick flag in postcopy_recover_triggered.

Now the facility is already there.

Drop postcopy_recover_triggered and instead allows a new migrate-recover to
release the previous listener transport.

a39e933962 migration: Move channel setup out of postcopy_try_recover()
We used to use postcopy_try_recover() to replace migration_incoming_setup() to
setup incoming channels.  That's fine for the old world, but in the new world
there can be more than one channels that need setup.  Better move the channel
setup out of it so that postcopy_try_recover() only handles the last phase of
switching to the recovery phase.

To do that in migration_fd_process_incoming(), move the postcopy_try_recover()
call to be after migration_incoming_setup(), which will setup the channels.
While in migration_ioc_process_incoming(), postpone the recover() routine right
before we'll jump into migration_incoming_process().

A side benefit is we don't need to pass in QEMUFile* to postcopy_try_recover()
anymore.  Remove it.

83174765da migration: Postpone releasing MigrationState.hostname
We used to release it right after migrate_fd_connect().  That's not good
enough when there're more than one socket pair required, because it'll be
needed to establish TLS connection for the rest channels.

One example is multifd, where we copied over the hostname for each channel
but that's actually not needed.

Keeping the hostname until the cleanup phase of migration.

b3caa7b55e tests: introduce ability to provide hooks for migration precopy test
There are alot of different scenarios to test with migration due to the
wide number of parameters and capabilities available. To enable sharing
of the basic precopy test scenario, we need to be able to set arbitrary
parameters and capabilities before the migration is initiated, but don't
want to have all this logic in the common helper function. Solve this
by defining two hooks that can be provided by the test case, one before
migration starts and one after migration finishes.

4b2bbca7a0 migration: fix use of TLS PSK credentials with a UNIX socket
The migration TLS code has a check mandating that a hostname be
available when starting a TLS session. This is expected when using
x509 credentials, but is bogus for PSK and anonymous credentials
as neither involve hostname validation.

The TLS crdentials object gained suitable error reporting in the
case of TLS with x509 credentials, so there is no longer any need
for the migration code to do its own (incorrect) validation.

724eaecec6 target/rx: update PC correctly in wait instruction
`cpu_pc` at this point does not necessary point to the current
instruction (i.e., the wait instruction being translated), so it's
incorrect to calculate the new value of `cpu_pc` based on this. It must
be updated with `ctx->base.pc_next`, which contains the correct address
of the next instruction.

This change fixes the wait instruction skipping the subsequent branch
when used in an idle loop like this:

    0:  wait

47430775ed python/qmp: remove pylint workaround from legacy.py
Pylint upgraded recently (2.13.z) and having a pylint: disable comment
in the middle of an argument field causes it some grief (It appears to
stop parsing when it encounters it, causing some syntax problems). Since
the duplicate line threshold was bumped up in 22305c2a08, we don't
need this workaround anymore. Drop it.

37094b6dd5 python: rename qemu.aqmp to qemu.qmp
Now that we are fully switched over to the new QMP library, move it back
over the old namespace. This is being done primarily so that we may
upload this package simply as "qemu.qmp" without introducing confusion
over whether or not "aqmp" is a new protocol or not.

The trade-off is increased confusion inside the QEMU developer
tree. Sorry!

Note: the 'private' member "_aqmp" in legacy.py also changes to "_qmp";
not out of necessity, but just to remove any traces of the "aqmp"
name.
