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().

Just like on other architectures, we should stop the clock while the guest
is not running. This is already properly done for TCG. Right now, doing an
offline migration (stop, migrate, cont) can easily trigger stalls in the
guest.
Even doing a
(hmp) stop
... wait 2 minutes ...
(hmp) cont
will already trigger stalls.
So whenever the guest stops, backup the KVM TOD. When continuing to run
the guest, restore the KVM TOD.
One special case is starting a simple VM: Reading the TOD from KVM to
stop it right away until the guest is actually started means that the
time of any simple VM will already differ to the host time. We can
simply leave the TOD running and the guest won't be able to recognize
it.
For migration, we actually want to keep the TOD stopped until really
starting the guest. To be able to catch most errors, we should however
try to set the TOD in addition to simply storing it. So we can still
catch basic migration problems.
If anything goes wrong while backing up/restoring the TOD, we have to
ignore it (but print a warning). This is then basically a fallback to
old behavior (TOD remains running).
I tested this very basically with an initrd:
1. Start a simple VM. Observed that the TOD is kept running. Old
behavior.
2. Ordinary live migration. Observed that the TOD is temporarily
stopped on the destination when setting the new value and
correctly started when finally starting the guest.
3. Offline live migration. (stop, migrate, cont). Observed that the
TOD will be stopped on the source with the "stop" command. On the
destination, the TOD is temporarily stopped when setting the new
value and correctly started when finally starting the guest via
"cont".
4. Simple stop/cont correctly stops/starts the TOD. (multiple stops
or conts in a row have no effect, so works as expected)
In the future, we might want to send the guest a special kind of time sync
interrupt under some conditions, so it can synchronize its tod to the
host tod. This is interesting for migration scenarios but also when we
get time sync interrupts ourselves. This however will most probably have
to be handled in KVM (e.g. when the tods differ too much) and is not
desired e.g. when debugging the guest (single stepping should not
result in permanent time syncs). I consider something like that an add-on
on top of this basic "don't break the guest" handling.

The 'q35' machine type implements an Intel Series 3 chipset,
of which there are several variants:
https://www.intel.com/Assets/PDF/datasheet/316966.pdf
The key difference between the 82P35 MCH ('p35', PCI device ID 0x29c0)
and 82Q35 GMCH ('q35', PCI device ID 0x29b0) variants is that the latter
has an integrated graphics adapter. QEMU does not implement integrated
graphics, so uses the PCI ID for the 82P35 chipset, despite calling the
machine type 'q35'. Thus we rename the PCI device ID constant to reflect
reality, to avoid confusing future developers. The new name more closely
matches what pci.ids reports it to be:
$ grep P35 /usr/share/hwdata/pci.ids | grep 29
29c0 82G33/G31/P35/P31 Express DRAM Controller
29c1 82G33/G31/P35/P31 Express PCI Express Root Port
29c4 82G33/G31/P35/P31 Express MEI Controller
29c5 82G33/G31/P35/P31 Express MEI Controller
29c6 82G33/G31/P35/P31 Express PT IDER Controller
29c7 82G33/G31/P35/P31 Express Serial KT Controller
$ grep Q35 /usr/share/hwdata/pci.ids | grep 29
29b0 82Q35 Express DRAM Controller
29b1 82Q35 Express PCI Express Root Port
29b2 82Q35 Express Integrated Graphics Controller
29b3 82Q35 Express Integrated Graphics Controller
29b4 82Q35 Express MEI Controller
29b5 82Q35 Express MEI Controller
29b6 82Q35 Express PT IDER Controller
29b7 82Q35 Express Serial KT Controller
Arguably the QEMU machine type should be named 'p35'. At this point in
time, however, it is not worth the churn for management applications &
documentation to worry about renaming it.

PKU is supported in Skylake Server (Only Server) and later, and
on Intel(R) Xeon(R) Processor Scalable Family. So PKU is supposed
to be in Skylake-Server CPU model. And PKU's CPUID has been
exposed to QEMU. But PKU can't be find in Skylake-Server CPU
model in the code. So this patch will fix this issue in
Skylake-Server CPU model.

With all required memory device class functions in place, we can factor
out pre_plug handling of memory devices. Take proper care of errors. We
still have to carry along legacy_align required for pc compatibility
handling.
We will factor out tracing of the address separately in a follow-up
patch.

To be able to factor out address assignment of memory devices, we will
have to read (get_addr()) and write (set_addr()) the address.
We can't use properties for this purpose, as properties are device
specific. E.g. while the address property for a DIMM is called "addr", it
might be called differently (e.g. "memaddr") for other devices.
Especially virtio based memory devices cannot use "addr" as that is already
reserved and used for the address on the bus (for the proxy device).
Also, it might be possible to have memory devices without address
properties (e.g. internal DIMM-like thingies).
In contrast to get_addr(), we expect that set_addr() can fail.
Keep it simple for now for pc-dimm and simply set the static property, that
will fail once realized.

There are no remaining users of get_region_size() except
memory_device_get_region_size() itself. We can make
memory_device_get_region_size() work directly on get_memory_region()
instead and drop get_region_size().
In addition, we can now use memory_device_get_region_size() in pc-dimm
code to implement get_plugged_size()"

The memory region is necessary for plugging/unplugging a memory device.
The region size (via get_region_size()) is no longer sufficient, as
besides the alignment, also the region itself is required in order to
add it to the device memory region of the machine via
- memory_region_add_subregion
- memory_region_del_subregion
So, to factor out plugging/unplugging of memory devices from pc-dimm
code, we have to factor out access to the memory region first.

We will factor out get_memory_region() from pc-dimm to memory device code
soon. Once that is done, get_region_size() can be implemented
generically and essentially be replaced by
memory_device_get_region_size (and work only on get_memory_region()).
We have some users of get_memory_region() (spapr and pc-dimm code) that are
only interested in the size. So let's rework them to use
memory_device_get_region_size() first, then we can factor out
get_memory_region() and eventually remove get_region_size() without
touching the same code multiple times.

Document the functions. Don't document get_region_size(), as we will be
dropping/replacing that one soon.
Use same documentation style as in include/exec/memory.h, but don't
document the parameters, as they are self-explanatory.

Let's properly forward the errors, so errors from get_region_size() /
get_plugged_size() can be handled.
Users right now call both functions after the device has been realized,
which is will never fail, so it is fine to continue using error_abort.
While at it, remove a leftover error check (suggested by Igor).

The previous commit changed vfio's warning messages from
vfio warning: DEV-NAME: Could not frobnicate
to
warning: vfio DEV-NAME: Could not frobnicate
To match this change, change error messages from
vfio error: DEV-NAME: On fire
to
vfio DEV-NAME: On fire
Note the loss of "error". If we think marking error messages that way
is a good idea, we should mark *all* error messages, i.e. make
error_report() print it.
