a09d2038cc pcie: Fast PCIe root ports for new machines
Change the default speed and width for new machine types to the
fastest and widest currently supported.  This should be compatible to
the PCIe 4.0 spec.  Pre-QEMU-4.0 machine types remain at 2.5GT/s, x1
width.

d26e543891 vfio/pci: Remove PCIe Link Status emulation
Now that the downstream port will virtually negotiate itself to the
link status of the downstream device, we can remove this emulation.
It's not clear that it was every terribly useful anyway.

c2a490e344 pcie: Allow generic PCIe root port to specify link speed and width
Allow users to experimentally specify speed and width values for the
generic PCIe root port.  Defaults remain at 2.5GT/s & x1 for
compatiblity with the intent to only support changing defaults via
machine types for now.

Note for libvirt testing that pcie-root-port controllers are given
default names like "pci.7" which don't play well with using the
"-set device.$name.$prop=$value" options accessible to us via
<qemu:commandline> options.  The solution is to add an <alias> to the
pcie-root-port <controller>, for example:

    <controller type='pci' index='7' model='pcie-root-port'>
      <model name='pcie-root-port'/>
      <target chassis='7' port='0x15'/>
      <alias name='ua-gfx0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x5'/>
    </controller>

The "ua-" here is a mandatory prefix.  We can then use:

  <qemu:commandline>
    <qemu:arg value='-set'/>
    <qemu:arg value='device.ua-gfx0.x-speed=8'/>
    <qemu:arg value='-set'/>
    <qemu:arg value='device.ua-gfx0.x-width=16'/>
  </qemu:commandline>

or, without an alias, set globals such as:

  <qemu:commandline>
    <qemu:arg value='-global'/>
    <qemu:arg value='pcie-root-port.x-speed=8'/>
    <qemu:arg value='-global'/>
    <qemu:arg value='pcie-root-port.x-width=16'/>
  </qemu:commandline>

3d67447fe7 pcie: Fill PCIESlot link fields to support higher speeds and widths
Make use of the PCIESlot speed and width fields to update link
information beyond those configured in pcie_cap_v1_fill().  This is
only called for devices supporting a version 2 capability and
automatically skips any non-PCIESlot devices.  Only devices with
increased link values generate any visible config space differences.

727b48661f pci: Sync PCIe downstream port LNKSTA on read
The PCIe link speed and width between a downstream device and its
upstream port is negotiated on real hardware and susceptible to
dynamic changes due to signal issues and power management.  In the
emulated device case there is no real hardware link, but we still
might wish to have some consistency between endpoint and downstream
port via a virtual negotiation.  There is of course a real link for
assigned devices and this same virtual negotiation allows the
downstream port to match the endpoint, synchronizing on every read
to support underlying physical hardware dynamically adjusting the
link.

This negotiation is intentionally unidirectional for compatibility.
If the endpoint exceeds the capabilities of the downstream port or
there is no endpoint device, the downstream port reports negotiation
to its maximum speed and width, matching the previous case where
negotiation was absent.  De-tuning the endpoint to match a virtual
link doesn't seem to benefit anyone and is a condition we've thus
far reported without functional issues.

Note that PCI_EXP_LNKSTA is already ignored for migration
compatibility via pcie_cap_v1_fill().

e7176cdbe4 hw/pci-bridge: Fix invalid free()
When loadvm'ing a *running* snapshot qemu crashes due to an invalid
free. It's fortunately caught early by glibc heap memory corruption
protection and qemu gets killed with SIGABRT.

Steps to reproduce:

1) Create VM (e.g w/ virsh define)
2) Start the VM and take a snapshot while it's running and having a
   PCI bridge attached
3) Destroy the VM and revert the running snapshot.

This commit fixes the issue.

f6e501a28e virtio: Provide version-specific variants of virtio PCI devices
Many of the current virtio-*-pci device types actually represent
3 different types of devices:
* virtio 1.0 non-transitional devices
* virtio 1.0 transitional devices
* virtio 0.9 ("legacy device" in virtio 1.0 terminology)

That would be just an annoyance if it didn't break our device/bus
compatibility QMP interfaces.  With these multi-purpose device
types, there's no way to tell management software that
transitional devices and legacy devices require a Conventional
PCI bus.

The multi-purpose device types would also prevent us from telling
management software what's the PCI vendor/device ID for them,
because their PCI IDs change at runtime depending on the bus
where they were plugged.

This patch adds separate device types for each of those virtio
device flavors:

- virtio-*-pci: the existing multi-purpose device types
  - Configurable using `disable-legacy` and `disable-modern`
    properties
  - Legacy driver support is automatically enabled/disabled
    depending on the bus where it is plugged
  - Supports Conventional PCI and PCI Express buses
    (but Conventional PCI is incompatible with
    disable-legacy=off)
  - Changes PCI vendor/device IDs at runtime
- virtio-*-pci-transitional: virtio-1.0 device supporting legacy drivers
  - Supports Conventional PCI buses only, because
    it has a PIO BAR
- virtio-*-pci-non-transitional: modern-only
  - Supports both Conventional PCI and PCI Express buses

The existing TYPE_* macros for these types will point to an
abstract base type, so existing casts in the code will keep
working for all variants.

A simple test script (tests/acceptance/virtio_version.py) is
included, to check if the new device types are equivalent to
using the `disable-legacy` and `disable-modern` options.

After analyzing the log information, it seems that qemu doesn't
change the Link Status from active to inactive after hot-unplug.
This results in the abnormal log after the linux kernel commit
d331710ea78fea merged.

Furthermore, If I hotplug the same virtio-blk disk after hot-unplug,
the virtio-blk would turn on and then back off.

So this patch set the Link Status inactive after hot-unplug and
active after hot-plug.

fb06411210 qmp hmp: Make system_wakeup check wake-up support and run state
The qmp/hmp command 'system_wakeup' is simply a direct call to
'qemu_system_wakeup_request' from vl.c. This function verifies if
runstate is SUSPENDED and if the wake up reason is valid before
proceeding. However, no error or warning is thrown if any of those
pre-requirements isn't met. There is no way for the caller to
differentiate between a successful wakeup or an error state caused
when trying to wake up a guest that wasn't suspended.

This means that system_wakeup is silently failing, which can be
considered a bug. Adding error handling isn't an API break in this
case - applications that didn't check the result will remain broken,
the ones that check it will have a chance to deal with it.

Adding to that, the commit before previous created a new QMP API called
query-current-machine, with a new flag called wakeup-suspend-support,
that indicates if the guest has the capability of waking up from suspended
state. Although such guest will never reach SUSPENDED state and erroring
it out in this scenario would suffice, it is more informative for the user
to differentiate between a failure because the guest isn't suspended versus
a failure because the guest does not have support for wake up at all.

All this considered, this patch changes qmp_system_wakeup to check if
the guest is capable of waking up from suspend, and if it is suspended.
After this patch, this is the output of system_wakeup in a guest that
does not have wake-up from suspend support (ppc64):

(qemu) system_wakeup
wake-up from suspend is not supported by this guest
(qemu)

And this is the output of system_wakeup in a x86 guest that has the
support but isn't suspended:

(qemu) system_wakeup
Unable to wake up: guest is not in suspended state
(qemu)

'guest-suspend-hybrid' to mention that both commands relies now
on the proper support for wake up from suspend, retrieved by the
'wakeup-suspend-support' attribute of the 'query-current-machine'
QMP command.

46ea94ca9c qmp: query-current-machine with wakeup-suspend-support
When issuing the qmp/hmp 'system_wakeup' command, what happens in a
nutshell is:

- qmp_system_wakeup_request set runstate to RUNNING, sets a wakeup_reason
and notify the event
- in the main_loop, all vcpus are paused, a system reset is issued, all
subscribers of wakeup_notifiers receives a notification, vcpus are then
resumed and the wake up QAPI event is fired

Note that this procedure alone doesn't ensure that the guest will awake
from SUSPENDED state - the subscribers of the wake up event must take
action to resume the guest, otherwise the guest will simply reboot. At
this moment, only the ACPI machines via acpi_pm1_cnt_init and xen_hvm_init
have wake-up from suspend support.

However, only the presence of 'system_wakeup' is required for QGA to
support 'guest-suspend-ram' and 'guest-suspend-hybrid' at this moment.
This means that the user/management will expect to suspend the guest using
one of those suspend commands and then resume execution using system_wakeup,
regardless of the support offered in system_wakeup in the first place.

This patch creates a new API called query-current-machine [1], that holds
a new flag called 'wakeup-suspend-support' that indicates if the guest
supports wake up from suspend via system_wakeup. The machine is considered
to implement wake-up support if a call to a new 'qemu_register_wakeup_support'
is made during its init, as it is now being done inside acpi_pm1_cnt_init
and xen_hvm_init. This allows for any other machine type to declare wake-up
support regardless of ACPI state or wakeup_notifiers subscription, making easier
for newer implementations that might have their own mechanisms in the future.

This is the expected output of query-current-machine when running a x86
guest:

{"execute" : "query-current-machine"}
{"return": {"wakeup-suspend-support": true}}

Running the same x86 guest, but with the --no-acpi option:

{"execute" : "query-current-machine"}
{"return": {"wakeup-suspend-support": false}}

This is the output when running a pseries guest:

{"execute" : "query-current-machine"}
{"return": {"wakeup-suspend-support": false}}

With this extra tool, management can avoid situations where a guest
that does not have proper suspend/wake capabilities ends up in
inconsistent state (e.g.
https://github.com/open-power-host-os/qemu/issues/31).

[1] the decision of creating the query-current-machine API is based
on discussions in the QEMU mailing list where it was decided that
query-target wasn't a proper place to store the wake-up flag, neither
was query-machines because this isn't a static property of the
machine object. This new API can then be used to store other
dynamic machine properties that are scattered around the code
ATM. More info at:
https://lists.gnu.org/archive/html/qemu-devel/2018-05/msg04235.html

9254893882 qmp: Split ShutdownCause host-qmp into quit and system-reset
It is interesting to know whether the shutdown cause was 'quit' or
'reset', especially when using "--no-reboot". In that case, a management
layer can now determine if the guest wanted a reboot or shutdown, and
can act accordingly.

Changes the output of the reason in the iotests from 'host-qmp' to
'host-qmp-quit'. This does not break compatibility because
the field was introduced in the same version.

791a289bad tests/pvpanic: Make the pvpanic test independent of global_qtest
We want to get rid of global_qtest in the long run, thus do not
use the wrappers like inb() and outb() here anymore.

ac16ab753a tests/vmgenid: Make test independent of global_qtest
The biggest part has already been done in the previous patch, we now
only have to replace some few qmp() and readb() calls with the
corresponding qtest_*() functions to get there.

273e3d92cf tests/acpi-utils: Drop dependence on global_qtest
As a general rule, we prefer avoiding implicit global state
because it makes code harder to safely copy and paste without
thinking about the global state.  Adjust the helper code to
use explicit state instead, and update all callers.

bios-tables-test no longer depends on global_qtest, now that it
passes explicit state through the testsuite data; an assert
proves this fact (although we will get rid of it later, once
global_qtest is gone).

24c01ffa9d ivshmem-test: Drop dependence on global_qtest
Managing parallel connections to two different monitors via
the implicit global_qtest makes it hard to copy-and-paste code
to tests that are not aware of the implicit state.  Since we
have already fixed qpci to avoid global_qtest, we can now
simplify by not using global_qtest anywhere in ivshmem-test.

We can assert that the conversion is correct by checking that
global_qtest remains NULL throughout the test (a later patch
that changes global_qtest to not be a public global variable
will drop the assertions).

d786f78252 tests/libqos/pci: Make PCI access functions independent of global_qtest
QPCIBus already tracks QTestState, so use that state instead of an
implicit reliance on global_qtest.

Based on an earlier patch ("libqos: Use explicit QTestState for pci
operations") from Eric Blake.

139108f684 .shippable.yml: disable the win cross tests
The pkg.mxe.cc package repositories have been down for the last two
weeks causing the builds to fail when shippable re-builds the
containers.

This is really just a sticking plaster until we can get our own docker
hub images properly setup so we can avoid having dependencies on
external repos.

d9fe9db943 hardfloat: implement float32/64 comparison
Performance results for fp-bench:

Host: Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz
- before:
cmp-single: 110.98 MFlops
cmp-double: 107.12 MFlops
- after:
cmp-single: 506.28 MFlops
cmp-double: 524.77 MFlops

Note that flattening both eq and eq_signaling versions
would give us extra performance (695v506, 615v524 Mflops
for single/double, respectively) but this would emit two
essentially identical functions for each eq/signaling pair,
which is a waste.

Aggregate performance improvement for the last few patches:
