Gerd Hoffmann 0d33415a4e pcie: fast unplug when slot power is off
In case the slot is powered off (and the power indicator turned off too)
we can unplug right away, without round-trip to the guest.

Also clear pending attention button press, there is nothing to care
about any more.

Gerd Hoffmann d5daff7d31 pcie: implement slot power control for pcie root ports
With this patch hot-plugged pci devices will only be visible to the
guest if the guests hotplug driver has enabled slot power.

This should fix the hot-plug race which one can hit when hot-plugging
a pci device at boot, while the guest is in the middle of the pci bus
scan.

Gerd Hoffmann 23786d1344 pci: implement power state
This allows to power off pci devices.  In "off" state the devices will
not be visible.  No pci config space access, no pci bar access, no dma.

Default state is "on", so this patch (alone) should not change behavior.

Use case:  Allows hotplug controllers implement slot power.  Hotplug
controllers doing so should set the inital power state for devices in
the ->plug callback.

Eugenio Pérez 0351152b6f vdpa: Replace qemu_open_old by qemu_open at
There is no reason to keep using the old one, since we neither use the
variadics arguments nor open it with O_DIRECT.

Also, net_client_init1, the caller of net_init_vhost_vdpa, wants all
net_client_init_fun to use Error API, so it's a good step in that
direction.

Jason Wang d152cdd6f6 virtio: use virtio accessor to access packed event
We used to access packed descriptor event and off_wrap via
address_space_{write|read}_cached(). When we hit the cache, memcpy()
is used which is not atomic which may lead a wrong value to be read or
wrote.

This patch fixes this by switching to use
virito_{stw|lduw}_phys_cached() to make sure the access is atomic.

Julia Suvorova 211afe5c69 hw/i386/acpi-build: Deny control on PCIe Native Hot-plug in _OSC
There are two ways to enable ACPI PCI Hot-plug:

        * Disable the Hot-plug Capable bit on PCIe slots.

This was the first approach which led to regression [1-2], as
I/O space for a port is allocated only when it is hot-pluggable,
which is determined by HPC bit.

        * Leave the HPC bit on and disable PCIe Native Hot-plug in _OSC
          method.

This removes the (future) ability of hot-plugging switches with PCIe
Native hotplug since ACPI PCI Hot-plug only works with cold-plugged
bridges. If the user wants to explicitely use this feature, they can
disable ACPI PCI Hot-plug with:
        --global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off

Change the bit in _OSC method so that the OS selects ACPI PCI Hot-plug
instead of PCIe Native.

Julia Suvorova c318bef762 hw/acpi/ich9: Add compat prop to keep HPC bit set for 6.1 machine type
To solve issues [1-2] the Hot Plug Capable bit in PCIe Slots will be
turned on, while the switch to ACPI Hot-plug will be done in the
DSDT table.

Introducing 'x-keep-native-hpc' property disables the HPC bit only
in 6.1 and as a result keeps the forced 'reserve-io' on
pcie-root-ports in 6.1 too.

Igor Mammedov 2aa1842d6d pcie: rename 'native-hotplug' to 'x-native-hotplug'
Mark property as experimental/internal adding 'x-' prefix.

Property was introduced in 6.1 and it should have provided
ability to turn on native PCIE hotplug on port even when
ACPI PCI hotplug is in use is user explicitly sets property
on CLI. However that never worked since slot is wired to
ACPI hotplug controller.
Another non-intended usecase: disable native hotplug on slot
when APCI based hotplug is disabled, which works but slot has
'hotplug' property for this taks.

It should be relatively safe to rename it to experimental
as no users should exist for it and given that the property
is broken we don't really want to leave it around for much
longer lest users start using it.

Eugenio Pérez 14c81b2191 vhost: Fix last vq queue index of devices with no cvq
The -1 assumes that cvq device model is accounted in data_queue_pairs,
if cvq does not exists, but it's actually the opposite: Devices with
!cvq are ok but devices with cvq does not add the last queue to
data_queue_pairs.

This is not a problem to vhost-net, but it is to vhost-vdpa:
* Devices with cvq gets initialized at last data vq device model, not
at cvq one.
* Devices with !cvq never gets initialized, since last_index is the
first queue of the last device model.

Because of that, the right change in last_index is to actually add the
cvq, not to remove the missing one.

This is not a problem to vhost-net, but it is to vhost-vdpa, which
device model trust to reach the last index to finish starting the
device.

Also, as the previous commit, rename it to index_end.

Tested with vp_vdpa with host's vhost=on and vhost=off, with ctrl_vq=on
and ctrl_vq=off.

Laurent Vivier 4a778dac9e tests/qtest/virtio-net: fix hotplug test case
virtio-net-test has an hotplug testcase that is never executed.

This is because the testcase is attached to virtio-pci interface
rather than to virtio-net-pci.

if we don't reset the auto-converge counter,
it will continue to run with COLO running,
and eventually the system will hang due to the
CPU throttle reaching DEFAULT_MIGRATE_MAX_CPU_THROTTLE.

Richard Henderson f10e7b9f6f ppc patch queue for 2021-11-09
Here's the latest set of ppc related patches for qemu-6.2, which I
 hope will squeeze in just barely before the hard freeze.
 
 This set includes a change to MAINTAINERS moving maintainership of ppc
 from myself and Greg Kurz to Cédric le Goater and Daniel Henrique
 Barboza.  So, I expect this to be my last pull request as ppc
 maintainer.  It's been great, but it's time I moved onto other things.
 
 Apart from that, this patchset is mostly a lot of updates to TCG
 implementations of ISA 3.1 (POWER10) instructions from the El Dorado
 team.  There are also a handful of other fixes.

Nicholas Piggin 71e6fae3a9 spapr_numa.c: FORM2 table handle nodes with no distance info
A configuration that specifies multiple nodes without distance info
results in the non-local points in the FORM2 matrix having a distance of
0. This causes Linux to complain "Invalid distance value range" because
a node distance is smaller than the local distance.

Fix this by building a simple local / remote fallback for points where
distance information is missing.

David Gibson 14fe3222e5 target/ppc, hw/ppc: Change maintainers
As our day jobs and interests have moved onto other things, Greg and I have
been struggling to keep on top of maintainership of target/ppc and
associated pieces like the pseries and powernv machine types, with their
platform specific devices.

We've therefore discussed and plan to transfer maintainership to Cédric Le
Goater (primary) and Daniel Henrique Barboza (backup).  Cédric and Daniel
have been actively contributing to the area for some time, and they're
supported in this by their current employer, IBM, who has an obvious
interest in the platform.

Greg and I do plan to stay around in some capacity for at least the next
6 months, providing reviews and advice to assist the new maintainers into
the role.
