virtio: refresh vring region cache after updating a virtqueue size (2023-03-07 19:51:07 -0500)
----------------------------------------------------------------
virtio,pc,pci: features, fixes
Several features that landed at the last possible moment:
Passthrough HDM decoder emulation
Refactor cryptodev
RAS error emulation and injection
acpi-index support on non-hotpluggable slots
Dynamically switch to vhost shadow virtqueues at vdpa net migration
Plus a couple of bugfixes that look important to have in the release.

Introduce QCryptodevBackendType in cryptodev.json, also apply this to
related codes. Then we can drop 'enum CryptoDevBackendOptionsType'.
Note that `CRYPTODEV_BACKEND_TYPE_NONE` is *NOT* used by anywhere, so
drop it(no 'none' enum in QCryptodevBackendType).

We have already used qapi to generate crypto device types, this allows
to convert type to a string 'model', so the 'model' field is not
needed.
And the 'name' field is not used by any backend driver, drop it.

From: zhenwei pi <pizhenwei@bytedance.com>
Introduce cryptodev alg type in cryptodev.json, then apply this to
related codes, and drop 'enum CryptoDevBackendAlgType'.
There are two options:
1, { 'enum': 'QCryptodevBackendAlgType',
'prefix': 'CRYPTODEV_BACKEND_ALG',
'data': ['sym', 'asym']}
Then we can keep 'CRYPTODEV_BACKEND_ALG_SYM' and avoid lots of
changes.
2, changes in this patch(with prefix 'QCRYPTODEV_BACKEND_ALG').
To avoid breaking the rule of QAPI, use 2 here.

Introduce cryptodev service type in cryptodev.json, then apply this
to related codes. Now we can remove VIRTIO_CRYPTO_SERVICE_xxx
dependence from QEMU cryptodev.

Rather than exposing akcipher service/RSA algorithm to virtio crypto
device unconditionally, detect akcipher capability from akcipher
crypto framework. This avoids unsuccessful requests.

Move queue_index, CryptoDevCompletionFunc and opaque into struct
CryptoDevBackendOpInfo, then cryptodev_backend_crypto_operation()
needs an argument CryptoDevBackendOpInfo *op_info only. And remove
VirtIOCryptoReq from cryptodev. It's also possible to hide
VirtIOCryptoReq into virtio-crypto.c in the next step. (In theory,
VirtIOCryptoReq is a private structure used by virtio-crypto only)

Account OPS/BPS for crypto device, this will be used for 'query-stats'
QEMU monitor command and QoS in the next step.
Note that a crypto device may support symmetric mode, asymmetric mode,
both symmetric and asymmetric mode. So we use two structure to
describe the statistics of a crypto device.

From: zhenwei pi <pizhenwei@bytedance.com>
Add 'throttle-bps' and 'throttle-ops' limitation to set QoS. The
two arguments work with both QEMU command line and QMP command.
Example of QEMU command line:
-object cryptodev-backend-builtin,id=cryptodev1,throttle-bps=1600,\
throttle-ops=100
Example of QMP command:
virsh qemu-monitor-command buster --hmp qom-set /objects/cryptodev1 \
throttle-ops 100
or cancel limitation:
virsh qemu-monitor-command buster --hmp qom-set /objects/cryptodev1 \
throttle-ops 0

From: zhenwei pi <pizhenwei@bytedance.com>
Now we can use "query-stats" QMP command to query statistics of
crypto devices. (Originally this was designed to show statistics
by '{"execute": "query-cryptodev"}'. Daniel Berrangé suggested that
querying configuration info by "query-cryptodev", and querying
runtime performance info by "query-stats". This makes sense!)
Example:
~# virsh qemu-monitor-command vm '{"execute": "query-stats", \
"arguments": {"target": "cryptodev"} }' | jq
{
"return": [
{
"provider": "cryptodev",
"stats": [
{
"name": "asym-verify-bytes",
"value": 7680
},
...
{
"name": "asym-decrypt-ops",
"value": 32
},
{
"name": "asym-encrypt-ops",
"value": 48
}
],
"qom-path": "/objects/cryptodev0" # support asym only
},
{
"provider": "cryptodev",
"stats": [
{
"name": "asym-verify-bytes",
"value": 0
},
...
{
"name": "sym-decrypt-bytes",
"value": 5376
},
...
],
"qom-path": "/objects/cryptodev1" # support asym/sym
}
],
"id": "libvirt-422"

From: Eugenio Pérez <eperezma@redhat.com>
At this moment it is only possible to migrate to a vdpa device running
with x-svq=on. As a protective measure, the rewind of the inflight
descriptors was done at the destination. That way if the source sent a
virtqueue with inuse descriptors they are always discarded.
Since this series allows to migrate also to passthrough devices with no
SVQ, the right thing to do is to rewind at the source so the base of
vrings are correct.
Support for inflight descriptors may be added in the future.

This allows vhost_vdpa to track if it is safe to get the vring base from
the device or not. If it is not, vhost can fall back to fetch idx from
the guest buffer again.
No functional change intended in this patch, later patches will use this
field.

The function vhost.c:vhost_dev_stop fetches the vring base so the vq
state can be migrated to other devices. However, this is unreliable in
vdpa, since we didn't signal the device to suspend the queues, making
the value fetched useless.
Suspend the device if possible before fetching first and subsequent
vring bases.
Moreover, vdpa totally reset and wipes the device at the last device
before fetch its vrings base, making that operation useless in the last
device. This will be fixed in later patches of this series.

The function vhost.c:vhost_dev_stop calls vhost operation
vhost_dev_start(false). In the case of vdpa it totally reset and wipes
the device, making the fetching of the vring base (virtqueue state) totally
useless.
The kernel backend does not use vhost_dev_start vhost op callback, but
vhost-user do. A patch to make vhost_user_dev_start more similar to vdpa
is desirable, but it can be added on top.

This allows net to restart the device backend to configure SVQ on it.
Ideally, these changes should not be net specific and they could be done
in:
* vhost_vdpa_set_features (with VHOST_F_LOG_ALL)
* vhost_vdpa_set_vring_addr (with .enable_log)
* vhost_vdpa_set_log_base.
However, the vdpa net backend is the one with enough knowledge to
configure everything because of some reasons:
* Queues might need to be shadowed or not depending on its kind (control
vs data).
* Queues need to share the same map translations (iova tree).
Also, there are other problems that may have solutions but complicates
the implementation at this stage:
* We're basically duplicating vhost_dev_start and vhost_dev_stop, and
they could go out of sync. If we want to reuse them, we need a way to
skip some function calls to avoid recursiveness (either vhost_ops ->
vhost_set_features, vhost_set_vring_addr, ...).
* We need to traverse all vhost_dev of a given net device twice: one to
stop and get the vq state and another one after the reset to
configure properties like address, fd, etc.
Because of that it is cleaner to restart the whole net backend and
configure again as expected, similar to how vhost-kernel moves between
userspace and passthrough.
If more kinds of devices need dynamic switching to SVQ we can:
* Create a callback struct like VhostOps and move most of the code
there. VhostOps cannot be reused since all vdpa backend share them,
and to personalize just for networking would be too heavy.
* Add a parent struct or link all the vhost_vdpa or vhost_dev structs so
we can traverse them.

Although it does not make a big difference, its more correct and
simplifies the cleanup path in subsequent patches.
Move ram_block_discard_disable(false) call to the top of
vhost_vdpa_cleanup because:
* We cannot use vhost_vdpa_first_dev after dev->opaque = NULL
assignment.
* Improve the stack order in cleanup: since it is the last action taken

From: Eugenio Pérez <eperezma@redhat.com>
A vdpa net device must initialize with SVQ in order to be migratable at
this moment, and initialization code verifies some conditions. If the
device is not initialized with the x-svq parameter, it will not expose
_F_LOG so the vhost subsystem will block VM migration from its
initialization.
Next patches change this, so we need to verify migration conditions
differently.
QEMU only supports a subset of net features in SVQ, and it cannot
migrate state that cannot track or restore in the destination. Add a
migration blocker if the device offers an unsupported feature.

Next patches enable devices to be migrated even if vdpa netdev has not
been started with x-svq. However, not all devices are migratable, so we
need to block migration if we detect that.
Block migration if we detect the device expose a feature SVQ does not
know how to work with.

Since some actions move to the start function instead of init, the
device features may not be the parent vdpa device's, but the one
returned by vhost backend. If transition to SVQ is supported, the vhost
backend will return _F_LOG_ALL to signal the device is migratable.
Add VHOST_F_LOG_ALL. HW dirty page tracking can be added on top of this
change if the device supports it in the future.

which broke acpi tables test and rebuild due to skipping some tests
even thought none of devices tests depend on weren't disabled.
As result it leads to some expected tables not being updated,
merge conflicts and tests failure.

test bridge AML generator with ACPI PCI hotplug disabled
(i.e. with native hotplug enabled/disabled per bridge/root port)
PS:
while at make sure that devices on pci-bridge are starting
from addr=1.0 as slot 0 is not available there and test
passes only because of a bug in ACPI hotplug that will be
fixed by follow up patch

expected changes:
Basically adds devices present on root bus in form:
Device (SXX)
{
Name (_ADR, 0xYYYYYYYY) // _ADR: Address
}
On top of that For q35.noacpihp, all ACPI PCI hotplug
AML is removed and _OSC get native hotplug enabled:
CreateDWordField (Arg3, 0x04, CDW2)
CreateDWordField (Arg3, 0x08, CDW3)
Local0 = CDW3 /* \_SB_.PCI0._OSC.CDW3 */
- Local0 &= 0x1E
+ Local0 &= 0x1F
If ((Arg1 != One))
{
CDW1 |= 0x08

Following corner case wasn't covered:
-device pcie-root-port,id=NO_HOTPLUG,hotplug=off
-device pcie-root-port,bus=NO_HOTPLUG
when intermediate root-port has explicitly disabled hotplug,
all hierarchy below it is not described anymore (used to be
described in 7.2)
So as result we see only NO_HOTPLUG root-port described
+ Device (S50)
+ {
+ Name (_ADR, 0x000A0000) // _ADR: Address
+ }
and no children nor notification chain for them are being composed.
Follow up patches will fix missing leaf root-port descriptor
and notification chain that should accompany it.

following change is expected:

I practice [1] hasn't broke anything since on hardware side we unset
hotplug_handler on such intermediate port => hotplug behind it has
not been properly wired and as result not worked.

(I practice [1] hasn't broke anything since on hardware side we unset
hotplug_handler on such intermediate port => hotplug behind it has
never worked)
When deciding if bridge should be described, the original
condition was
cold_plugged_bridge && pcihp_bridge_en
which was replaced [1] by
bridge has ACPI_PCIHP_PROP_BSEL
the later however is not the same thing as the original
and flips to false if intermediate bridge has hotplug
turned off (root-port with 'hotplug=off' option).
Since we already in build_pci_bridge_aml(), the question
if it's bridge is answered. Use DeviceState::hotplugged
to make decision if bridge should describe its slots.
What's left out is pcihp_bridge_en, which tells us if
ACPI bridge hotplug is enabled.
With hotplug and non hotplug part now being mostly
separated, omitting this check will only lead to
colplugged bridges describe occupied slots in case
when ACPI bridge hotplug is disabled.
Which makes behavior consistent with occupied slots
on hostbridge.
Ex (pc/DSDT.hpbrroot diff):
...
Device (S20)
{
Name (_ADR, 0x00040000) // _ADR: Address
+ Device (S08)
+ {
+ Name (_ADR, 0x00010000) // _ADR: Address
+ }
+
+ Device (S10)
+ {
+ Name (_ADR, 0x00020000) // _ADR: Address
+ }
}
...
PS:
testing shows that above doesn't affect adversely guest OS
behavior: i.e. if ACPI bridge hotplug is enabled it's
expected behaviour, and with ACPI bridge hotplug is disabled
(a.k. native hotplug), it doesn't break slot enumeration
nor native hotplug. (tested with RHEL9.0 and WS2022).

commit [1] added ability to disable ACPI PCI hotplug
on hostbridge but forgot to take into account that it
should disable all ACPI hotplug machinery in case both
hostbridge and bridge hotplug are disabled.
Commit [2] tried to fix that, however it forgot to
remove hotplug_handler override which hands hotplug
control over to piix4 hotplug controller
(uninitialized after [2]).
As result at the time bridge is plugged in, its default
(SHPC) hotplug handler is replaced by piix4 one in
acpi_pcihp_device_plug_cb()
...
if (!s->legacy_piix &&
...
qbus_set_hotplug_handler(BUS(sec), OBJECT(hotplug_dev));
which is acting on uninitialized s->legacy_piix value
(0 by default) that was supposed to be initialized by
acpi_pcihp_init(), that is no longer called due to
following condition being false:
piix4_acpi_system_hot_add_init()
if (s->use_acpi_hotplug_bridge || s->use_acpi_root_pci_hotplug) {
and the bridge ends up with piix4 as hotplug handler
instead of shpc one.
Followup hotplug on that bridge as result yields
piix4 specific error:
Error: Unsupported bus. Bus doesn't have property 'acpi-pcihp-bsel' set
1) 3d7e78aa777 (Introduce a new flag for i440fx to disable PCI hotplug on the root bus)
2) df4008c9c59 (piix4: don't reserve hw resources when hotplug is off globally)

Currently the property may flip its state
during VM bring up or just doesn't work as
the name implies.
In particular with PCIE root port that has
'hotplug={on|off}' property, and when it's
turned off, one would expect
'hotpluggable' == false
for any devices attached to it.
Which is not the case since qbus_is_hotpluggable()
used by the property just checks for presence
of any hotplug_handler set on bus.
The problem is that name BusState::hotplug_handler
from its inception is misnomer, as it handles
not only hotplug but also in many cases coldplug
as well (i.e. generic wiring interface), and
it's fine to have hotplug_handler set on bus
while it doesn't support hotplug (ex. pcie-slot
with hotplug=off).
Another case of root port flipping 'hotpluggable'
state when ACPI PCI hotplug is enabled in this
case root port with 'hotplug=off' starts as
hotpluggable and then later on, pcihp
hotplug_handler clears hotplug_handler
explicitly after checking root port's 'hotplug'
property.
So root-port hotpluggablity check sort of works
if pcihp is enabled but is broken if pcihp is
disabled.
One way to deal with the issue is to ask
hotplug_handler if bus it controls is hotpluggable
or not. To do that add is_hotpluggable_bus()
hook to HotplugHandler interface and use it in
'hotpluggable' property + teach pcie-slot to
actually look into 'hotplug' property state
before deciding if bus is hotpluggable.

it will be reused by follow up patches that will implement
static _DSM for non-hotpluggable devices.
no functional AML change, only context one, where 'cap' (Local1)

From: Igor Mammedov <imammedo@redhat.com>
it's a helper method for acpi-index support on PCI buses
that do no support or have disabled ACPI PCI hotplug
or for non-hotpluggble endpoint devices.
(like non-hotpluggble NICs, integrated endpoints and
later for machines that do not support ACPI PCI hotplug)
no functional change, commit adds only EDSM method in DSDT
without any users. (the follow up patches will use it)

Inject static _DSM (EDSM) if non-hotpluggable device has
acpi-index configured on it.
It lets use acpi-index non-hotpluggable devices / devices
attached to non-hotpluggable bus.

the only chenge is addition of _DSM- > EDSM method
on non-hotpluggable devices with configured acpi-index.
Something like:
+ Method (_DSM, 4, Serialized) // _DSM: Device-Specific Method
+ {
+ Local0 = Package (0x01)
+ {
+ 0x65
+ }
+ Return (EDSM (Arg0, Arg1, Arg2, Arg3, Local0))

From: Igor Mammedov <imammedo@redhat.com>
describing all present devices on functions other than
0 was complicated when non hotplug and hotplug code
was intermixed. So QEMU has been excluding non zero
functions since they are not supported by hotplug code,
then a condition to whitelist coldplugged bridges was
added and later whitelisting of devices that advertise
presence of their own AML description.
With non hotplug and hotplug code separated, it is
possible to relax rules and allow describing all
non-hotpluggble functions and hence simplify
conditions whether PCI device should be enumerated by
generic (non-hotplug) code.
Price of that simplification is an extra few Device()
descriptors in DSDT exposing built-in chipset functions,
which has no functional effect on guest side.
Apart from that, the enumeration of non zero functions,
allows to attach more NICs with acpi-index enabled
directly on hostbridge (if hotplug is not required).

From: Igor Mammedov <imammedo@redhat.com>
acpi-index is now working with non-hotpluggable buses
(pci/q35 machine hostbridge), it can be used even if
ACPI PCI hotplug is disabled and as result acpi-index
uniqueness check will be omitted (since the check is
done by ACPI PCI hotplug handler, which isn't wired
when ACPI PCI hotplug is disabled).
Move check and related code to generic PCIDevice so it
would be independent of ACPI PCI hotplug.

From: Igor Mammedov <imammedo@redhat.com>
previous commit ("pci: fix 'hotplugglable' property behavior") fixed
pcie root port's 'hotpluggable' property to behave consistently.
So we don't need a BSEL crutch anymore to see of device is not
hotpluggable, drop it from 'generic' PCI slots description handling.
BSEL is still used to decide if hotplug part should be called
but that will be moved out of generic code to hotplug one by
followup patches.

From: Igor Mammedov <imammedo@redhat.com>
Generic PCI enumeration code doesn't really need access to
BSEL value, it is only used as means to decide if hotplug
enumerator should be called.
Use stateless object_property_find() to do that, and move
the rest of BSEL handling into build_append_pcihp_slots()
where it belongs.
This cleans up generic code a bit from hotplug stuff
and follow up patch will remove remaining call to
build_append_pcihp_slots() from generic code, making
it possible to use without ACPI PCI hotplug dependencies.

From: Igor Mammedov <imammedo@redhat.com>
Provide pcihp specific callback to check if bus is hotpluggable
and consolidate its scattered hotplug criteria there.
While at it clean up no longer needed
qbus_set_hotplug_handler(BUS(bus), NULL)
workarounds since callback makes qbus_is_hotpluggable() return
correct answer even if hotplug_handler is set on bus.
PS:
see ("pci: fix 'hotplugglable' property behavior") for details
why callback was introduced.

This register in AER should be both writeable and should
have a default value with a couple of the errors masked
including the Uncorrectable Internal Error used by CXL for
it's error reporting.

PCIe r6.0 Figure 6-3 "Pseudo Logic Diagram for Selected Error Message Control
and Status Bits" includes a right hand branch under "All PCI Express devices"
that allows for messages to be generated or sent onwards without SERR#
being set as long as the appropriate per error class bit in the PCIe
Device Control Register is set.
Implement that branch thus enabling routing of ERR_COR, ERR_NONFATAL
and ERR_FATAL under OSes that set these bits appropriately (e.g. Linux)

As these are about to be modified, fix the endian handle for
this set of registers rather than making it worse.
Note that CXL is currently only supported in QEMU on
x86 (arm64 patches out of tree) so we aren't going to yet hit
an problems with big endian. However it is good to avoid making
things worse for that support in the future.

CXL uses PCI AER Internal errors to signal to the host that an error has
occurred. The host can then read more detailed status from the CXL RAS
capability.
For uncorrectable errors: support multiple injection in one operation
as this is needed to reliably test multiple header logging support in an
OS. The equivalent feature doesn't exist for correctable errors, so only
one error need be injected at a time.
Note:
- Header content needs to be manually specified in a fashion that
matches the specification for what can be in the header for each
error type.
Injection via QMP:

These two helpers enable host bridges to operate differently depending on
the number of downstream ports, in particular if there is only a single
port.
Useful for CXL where HDM address decoders are allowed to be implicit in
the host bridge if there is only a single root port.

The CXL r3.0 specification allows for there to be no HDM decoders on CXL
Host Bridges if they have only a single root port. Instead, all accesses
directed to the host bridge (as specified in CXL Fixed Memory Windows)
are assumed to be routed to the single root port.
Linux currently assumes this implementation choice. So to simplify testing,
make QEMU emulation also default to no HDM decoders under these particular
circumstances, but provide a hdm_for_passthrough boolean option to have
HDM decoders as previously.
Technically this is breaking backwards compatibility, but given the only
known software stack used with the QEMU emulation is the Linux kernel
and this configuration did not work before this change, there are
unlikely to be any complaints that it now works. The option is retained
to allow testing of software that does allow for these HDM decoders to exist,
once someone writes it.

During protocol negotiation, when we the QEMU
stub does not support a backend with F_CONFIG,
it throws a warning and supresses the
VHOST_USER_PROTOCOL_F_CONFIG bit.
However, the warning uses warn_reportf_err macro
and passes an unitialized errp pointer. However,
the macro tries to edit the 'msg' member of the
unitialized Error and segfaults.
Instead, just use warn_report, which prints a
warning message directly to the output.

From: Carlos López <clopez@suse.de>
In virtqueue_{split,packed}_get_avail_bytes() descriptors are read
in a loop via MemoryRegionCache regions and calls to
vring_{split,packed}_desc_read() - these take a region cache and the
index of the descriptor to be read.
For direct descriptors we use a cache provided by the caller, whose
size matches that of the virtqueue vring. We limit the number of
descriptors we can read by the size of that vring:
max = vq->vring.num;
...
MemoryRegionCache *desc_cache = &caches->desc;
For indirect descriptors, we initialize a new cache and limit the
number of descriptors by the size of the intermediate descriptor:
len = address_space_cache_init(&indirect_desc_cache,
vdev->dma_as,
desc.addr, desc.len, false);
desc_cache = &indirect_desc_cache;
...
max = desc.len / sizeof(VRingDesc);
However, the first initialization of `max` is done outside the loop
where we process guest descriptors, while the second one is done
inside. This means that a sequence of an indirect descriptor followed
by a direct one will leave a stale value in `max`. If the second
descriptor's `next` field is smaller than the stale value, but
greater than the size of the virtqueue ring (and thus the cached
region), a failed assertion will be triggered in
address_space_read_cached() down the call chain.
Fix this by initializing `max` inside the loop in both functions.

When a virtqueue size is changed by the guest via
virtio_queue_set_num(), its region cache is not automatically updated.
If the size was increased, this could lead to accessing the cache out
of bounds. For example, in vring_get_used_event():
static inline uint16_t vring_get_used_event(VirtQueue *vq)
{
return vring_avail_ring(vq, vq->vring.num);
}
static inline uint16_t vring_avail_ring(VirtQueue *vq, int i)
{
VRingMemoryRegionCaches *caches = vring_get_region_caches(vq);
hwaddr pa = offsetof(VRingAvail, ring[i]);
if (!caches) {
return 0;
}
return virtio_lduw_phys_cached(vq->vdev, &caches->avail, pa);
}
vq->vring.num will be greater than caches->avail.len, which will
trigger a failed assertion down the call path of
virtio_lduw_phys_cached().
Fix this by calling virtio_queue_update_rings() after
virtio_queue_set_num() if we are not already calling
virtio_queue_set_rings().

Philippe, is tests/data/acpi/DSDT.nosmm in your tree for some reason?
Because it's not in mine:
$ git log -- tests/data/acpi/DSDT.nosmm
It's a side effect of how our tests work ATM that a presence of
a corrupted file in the source directory will confuse the test
and make it fail, and git reset will not be enough since some
of these can be untracked - you need git clean.

Tests pass after removing all of them. I forgot to check their
timestamp before removing, so I don't know how/when they appeared

Hi; in issue https://gitlab.com/qemu-project/qemu/-/issues/1586
it's been pointed out that this commit causes an assertion
failure during 'make check' if you configure with
--enable-qom-cast-debug. You can repro by doing that and running:
qemu-system-i386 -display none -machine q35,cxl=on -device pxb-cxl,bus=pcie.0
Here's a backtrace:
Thread 1 "qemu-system-i38" received signal SIGABRT, Aborted.

The problem is here:

This function is called from pxb_cxl_dev_realize(),
which is the realize function for TYPE_PXB_CXL_DEVICE.
That type's parent is TYPE_PCI_DEVICE.

However, here we try to cast the device pointer to PXB_DEV.
That is not permitted because dev is not of type TYPE_PXB_DEVICE
(either directly or as a parent class). So if you have the QOM
debugging enabled then the attempt to cast causes an assertion
failure.

What was the intention here with the type hierarchy?
Should TYPE_PXB_CXL_DEVICE be a subclass of TYPE_PXB_DEVICE,
or should the cxl-related functions not be trying to treat
it as a PXB device ?

Maybe we should simply revert the commit for the time being (once the 8.1
cycle begins), 'til this has properly been solved, so we can enable
qom-debug by default again?

Sorry - I missed this until today. Indeed revert makes sense. I'll chase this down
in the new cycle.

I can't immediately recall why, but PXB_DEV and PXB_CXL_DEV use the
same struct PXBDev so here switching to PXB_CXL_DEV(dev)->hdm_for_passthrough
looks to be the minimum fix.
I'll dig into why / if there is a good reason for why PXB_CXL_DEV doesn't
simply inherit from PXB_DEV then use runtime type checking in the few places it
will matter.

Ah. Looks to be cut and paste from what TYPE_PXB_PCIE_DEV was doing.
We probably never considered if that was a good path to take or not.
Not clear why they can't both just inherit from TYPE_PXB_DEV.
At least superficially it seems to work + is cleaner.
Following only lightly tested... May eat babies etc.

You probably want to send this out as a proper top-level patch:
both humans and automated tooling tend to not notice patches
buried inside other list threads.

This function looks super-dubious, so the fact that it
goes away in this patch is a good sign :-)

The documentation for DECLARE_INSTANCE_CHECKER()
says "Direct usage of this macro should be avoided, and
the complete OBJECT_DECLARE_TYPE() macro is recommended
instead. So we should do that. (That will also mean you don't
need the explicit "typedef"s on your struct declarations,
because OBJECT_DECLARE_TYPE() will define typedefs for you.)

Absolutely. Was a case of lazily throwing it over the wall before running out

I'll fix that up and send out properly. Thanks for the

This breaks the simplest migration from QEMU 8.0->7.2 binaries on all
machine types I think as long as the cap is present, e.g. the default
e1000e provided by the default q35 machine can already hit it with all
default cmdline:
./qemu-system-x86_64 -M pc-q35-7.2 [-incoming XXX]
7.2 binary will have empty wmask for PCI_ERR_UNCOR_MASK, meanwhile I think
it can also see a non-zero value, then the migration will fail at:
vmstate_load 0000:00:02.0/e1000e, e1000e
qemu-7.2: get_pci_config_device: Bad config data: i=0x10a read: 40 device: 0 cmask: ff wmask: 0 w1cmask:0
qemu-7.2: Failed to load PCIDevice:config
qemu-7.2: Failed to load e1000e:parent_obj
qemu-7.2: error while loading state for instance 0x0 of device '0000:00:02.0/e1000e'
qemu-7.2: load of migration failed: Invalid argument
We probably at least want to have the default value to be still zero, and
we'd need to make sure it'll not be modified by the guest, iiuc.
Below oneliner works for me and makes the migration work again:

My bad, I forgot about this 🤦.
So we need a property and tweak it with compat machinery depending on
machine type. Jonathan, can you work on this pls?
Or I can revert for now to relieve the time pressure,
redo the patch at your leasure.

I agree with Michael here, the best option is adding a new property.

Hi; Coverity points out (CID 1508074) that this change
introduces a memory leak:

object_get_canonical_path() already returns allocated memory
that the caller should free with g_free(), so we should not
g_strdup() it (which then leaks that memory).

Would somebody like to send a patch?

Thanks all. Sorry for lack of reply, crazy week at a conference, so I wasn't
successfully keeping up with email and still working through backlog.
Obviously I forgot about migration across versions. Sorry!
The fix Leo posted looks good to me. Given in theory a previously loaded
driver /firmware could have set these all to 0, any driver code should not
be assuming they take the defaults in the PCI spec. Might make a difference
to any testing using errors injected very early (e.g. before drivers load)
but meh, that's a corner case no one has hit previously so I doubt they ever will.
Thanks to all involved.
Jonathan
