QEMU currently exits unexpectedly when trying to introspect the fsl-imx6
and fsl-imx7 devices on systems with many SMP CPUs:
$ echo "{'execute':'qmp_capabilities'}"\
"{'execute':'device-list-properties',"\
" 'arguments':{'typename':'fsl,imx6'}}" \
| arm-softmmu/qemu-system-arm -M virt,accel=qtest -qmp stdio -smp 8
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
"package": "build-all"}, "capabilities": []}}
{"return": {}}
fsl,imx6: Only 4 CPUs are supported (8 requested)
And:
$ echo "{'execute':'qmp_capabilities'}"\
"{'execute':'device-list-properties',"\
" 'arguments':{'typename':'fsl,imx7'}}" \
| arm-softmmu/qemu-system-arm -M raspi2,accel=qtest -qmp stdio

"package": "build-all"}, "capabilities": []}}
{"return": {}}
fsl,imx7: Only 2 CPUs are supported (4 requested)
This happens because these devices are doing an exit() from their
instance_init function - which should never be done since instance_init
can be called at any time for device introspection! Fix it by moving
the deadly check into the realize() function instead.

The instance_init function of a device can be called at any time, even
if the device is not going to be used (i.e. not going to be realized).
So a instance_init function must not do things that could cause QEMU
to exit, like calling qemu_check_nic_model(&nd_table[0], ...) for example.
But this is what the instance_init function of the allwinner-a10 device
is currently doing - and this causes QEMU to quit unexpectedly when
you run the 'device-list-properties' QMP command for example:
$ echo "{'execute':'qmp_capabilities'}"\
"{'execute':'device-list-properties',"\
" 'arguments':{'typename':'allwinner-a10'}}" \
| arm-softmmu/qemu-system-arm -M mps2-an505,accel=qtest -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
"package": "build-all"}, "capabilities": []}}
{"return": {}}
Unsupported NIC model: lan9118
... and QEMU quits after printing the last line (which should not happen
just because of running 'device-list-properties' here).
And with the cubieboard, this even causes QEMU to abort():
$ echo "{'execute':'qmp_capabilities'}"\
"{'execute':'device-list-properties',"\
" 'arguments':{'typename':'allwinner-a10'}}" \
| arm-softmmu/qemu-system-arm -M cubieboard,accel=qtest -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
"package": "build-all"}, "capabilities": []}}
{"return": {}}

The Linux bcm2835_sdhost driver doesn't work on QEMU, because our
model raises spurious data interrupts. Our function
bcm2835_sdhost_fifo_run() will flag an interrupt any time it is
called with s->datacnt == 0, even if the host hasn't actually issued
a data read or write command yet. This means that the driver gets a
spurious data interrupt as soon as it enables IRQs and then does
something else that causes us to call the fifo_run routine, like
writing to SDHCFG, and before it does the write to SDCMD to issue the
read. The driver's IRQ handler then spins forever complaining that
there's no data and the SD controller isn't in a state where there's
going to be any data:
[ 41.040738] sdhost-bcm2835 3f202000.mmc: fsm 1, hsts 00000000
[ 41.042059] sdhost-bcm2835 3f202000.mmc: fsm 1, hsts 00000000
(continues forever).
Move the interrupt flag setting to more plausible places:
* for BUSY, raise this as soon as a BUSYWAIT command has executed
* for DATA, raise this when the FIFO has any space free (for a write)
or any data in it (for a read)
* for BLOCK, raise this when the data count is 0 and we've
actually done some reading or writing
This is pure guesswork since the documentation for this hardware is
not public, but it is sufficient to get the Linux bcm2835_sdhost
driver to work.

QEMU SCSI code makes assumptions about how the PROTECT and BYTCHK
works in the protocol, denying support for PI (Protection
Information) in case the guest OS requests it. However, in SCSI versions 2
and older, there is no PI concept in the protocol.
This means that when dealing with such devices:
- there is no PROTECT bit in byte 5 of the standard INQUIRY response. The
whole byte is marked as "Reserved";
- there is no RDPROTECT in byte 2 of READ. We have 'Logical Unit Number'
in this field instead;
- there is no VRPROTECT in byte 2 of VERIFY. We have 'Logical Unit Number'
in this field instead. This also means that the BYTCHK bit in this case
is not related to PI.
Since QEMU does not consider these changes, a SCSI passthrough using
a SCSI-2 device will not work. It will mistake these fields with
PI information and return Illegal Request SCSI SENSE thinking
that the driver is asking for PI support.
This patch fixes it by adding a new attribute called 'scsi_version'
that is read from the standard INQUIRY response of passthrough
devices. This allows for a version verification before applying
conditions related to PI that doesn't apply for older versions.

IPL over a virtio-scsi device requires special handling not
available in the real architecture. For this purpose the IPL
type 0xFF has been chosen as means of communication between
QEMU and the pc-bios. However, a guest OS could be confused
by seeing an unknown IPL type.
This change sets the IPL parameter type to 0x02 (CCW) to prevent
this. Pre-existing Linux has looked up the IPL parameters only in
the case of FCP IPL. This means that the behavior should stay
the same even if Linux checks for the IPL type unconditionally.

Operating systems may request an IPL from a virtio-scsi device
by specifying an IPL parameter type of CCW. In this case QEMU
won't set up the IPLB correctly. The BIOS will still detect
it's a SCSI device to boot from, but it will now have to search
for the first LUN and attempt to boot from there.
However this may not be the original boot LUN if there's more than
one SCSI disk attached to the HBA.
With this change QEMU will detect that the request is for a
SCSI device and will rebuild the initial IPL parameter info
if it's the SCSI device used for the first boot. In consequence
the BIOS can use the boot LUN from the IPL information block.
In case a different SCSI device has been set, the BIOS will find
and use the first available LUN.

Manually having to use cpu_synchronize_state() is error prone. And as
Christian Borntraeger discovered, e.g. handle_diag() is currently
missing a cpu_synchronize_state(), as decode_basedisp_s() uses a
general purpose register value internally.
So let's do an overall cpu_synchronize_state(), which fixes at least the
one mentioned BUG. We will clean up the superfluous cpu_synchronize_state()
calls later.
We now also call it (although maybe not neded) for
- KVM_EXIT_S390_RESET -> s390_reipl_request()
- KVM_EXIT_DEBUG -> kvm_arch_handle_debug_exit()
- unmanagable/unimplemented intercepts
- ICPT_CPU_STOP -> do_stop_interrupt() -> cpu gets halted
- Scenarios where we inject an operation exception
- handle_stsi()
I don't think any of these are performance critical. Especially as we
have all information directly contained in kvm_run, there are no
additional IOCTLs to issue on modern kernels.
