Hello Michael and Gerd,
As discussed, this series attempts to clean up PCIe devices fiddling with
individual PCI VMStateFields. It is based on my qom-devices queue, containing
changes to PCIe devices.
v2 has been changed to use VMStateField::field_exists instead of subsections
and unifies PCI and PCIe. Making MSI-X such a conditional field affects PCI, too,
now and therefore requires incompatible changes to VMXNET3 PCI NIC.
This has been successfully tested with a selection of PCI and PCIe devices
on -machine pc (-machine q35 is unfortunately unmigratable due to ich9-ahci)
and shows identically sized state files (for "exec:cat > pc-pci.state") and
no immediate crashes. Not 1.6 material.
A QOM follow-up RFC will be sent out shortly.
Regards,
Andreas
v1 -> v2:
* Prepended patches to drop VMSTATE_{PCI,PCIE}_DEVICE() arguments.
* Added patch to introduce VMSTATE_BUFFER_UNSAFE_INFO_TEST() macro.
* Unified PCI and PCIe VMStateDescriptions (mst).
* Instead of moving & turning into subsection, make AER log conditional field.
* Instead of subsection, make MSI-X a conditional field.

Use it conditional on msix_present() and drop msix_{save,load}() calls
following pci_device_{save,load}().
This reorders the msix_save() and msix_unuse_all_vectors() calls for
virtio-pci, but they seem independent of each other.

No, that's a bug. msix_unuse_all_vectors clears pending state
if any, it will lose state if called before load.

We discussed and discarded something very similar.
This only works correctly if you put it in a struct which has the pci
device at offset 0, and there's no either runtime or compile-time check
to verify it's the correct type.
So please find some other way to do this.
Or go back to give fields sane names instead
of "parent_obj".

This discards compiler check that macro is used
appropriately and does not add a runtime check.
We discussed and discarded this approach in
the previous round of patches you sent.
Yes "parent_obj" in code is ugly, but
this is not a good solution.

Anthony requested that I don't mix different types for the offsets in
VMSTATE_*() macros.

As Anthony already said, QOM depends on the offset being 0, casts will
fail otherwise. So there are runtime checks.

I did post an RFC, but that is significantly more invasive, since it
affects not only PCI and needs a lot of review before we can move
forward with it.

Exactly. The solution is *not* not to put any types there.

I don't see any runtime casts in vmstate.
That's exactly the issue. This is a bad API.
vmstate isn't limited to QOM objects, if you make
a macro without arguments it should either make
sense in any vmstate, make compilation fail
if misused, or at least quickly make migration fail
if misused.
Not corrupt random memory.
