according to Eduardo Habkost's commit fd3b02c889 all PCIEs now implement
INTERFACE_PCIE_DEVICE so we don't need is_express field anymore.
Devices that implements only INTERFACE_PCIE_DEVICE (is_express == 1)
or
devices that implements only INTERFACE_CONVENTIONAL_PCI_DEVICE (is_express == 0)
where not affected by the change.
The only devices that were affected are those that are hybrid and also
had (is_express == 1) - therefor only:
- hw/vfio/pci.c
- hw/usb/hcd-xhci.c
- hw/xen/xen_pt.c
For those 3 I made sure that QEMU_PCI_CAP_EXPRESS is on in instance_init()

The bus pointer in PCIDevice is basically redundant with QOM information.
It's always initialized to the qdev_get_parent_bus(), the only difference
is the type.
Therefore this patch eliminates the field, instead creating a pci_get_bus()
helper to do the type mangling to derive it conveniently from the QOM
Device object underneath.

vfio_populate_device())

The existing XHCI code reads the Event Ring Segment Table Base Address

This adds a check for ERSTBA in addition to the existing check for

When done processing a endpoint ring we must update the dequeue pointer
in the endpoint context in guest memory. This is needed to make sure
the guest has a correct view of things and also to make live migration
work properly, because xhci post_load restores alot of the state from
xhci data structures in guest memory.
Add xhci_set_ep_state() call to do that.
The recursive calls stopped by commit
ddb603ab6c had the (unintentional) side
effect to hiding this bug. xhci_set_ep_state() was called before
processing, to set the state to running, which updated the dequeue
pointer too.

The nec/renesas driver problems have finally been debugged and root
caused, see commit "7da76e1 xhci: fix event queue IRQ handling".
It's pretty clear now that
(a) The whole "driver can't handle ring full" story is most likely
wrong.
(b) The ER_FULL_HACK workaround based on the false assumtion doesn't
much. It avoids the driver crashing (without commit 7da76e1), but
it doesn't make usb work.
(c) With 7da76e1 applied it doesn't trigger any more.

The qemu xhci emulation doesn't handle the ERDP_EHB flag correctly.
When the host adapter queues a new event the ERDP_EHB flag is set. The
flag is cleared (via w1c) by the guest when it updates the ERDP (event
ring dequeue pointer) register to notify the host adapter which events
it has fetched.
An IRQ must be raised in case the ERDP_EHB flag flips from clear to set.
If the flag is set already (which implies there are events queued up
which are not yet processed by the guest) xhci must *not* raise a IRQ.
Qemu got that wrong and raised an IRQ on every event, thereby generating
spurious interrupts in case we've queued events faster than the guest
processed them. This patch fixes that.
With that change in place we also have to check ERDP updates, to see
whenever the guest has fetched all queued events. In case there are
still pending events set ERDP_EHB and raise an IRQ again, to make sure
the events don't linger unseen forever.
The linux kernel driver and the microsoft windows driver (shipped with
win8+) can deal with the spurious interrupts without problems. The
renesas windows driver (v2.1.39) which can be used on older windows
versions is quite upset though. It does spurious ERDP updates now and
then (not every time, seems we must hit a race window for this to
happen), which in turn makes the qemu xhci emulation think the event
ring is full. Things go south from here ...
tl;dr: This is the "fix xhci on win7" patch.

The vmstate_pci_device and vmstate_pcie_devices differ
just in the size of one buffer; combine the two using a _TEST

I think this is safe as long as everywhere which currently
uses either of these two uses the right type.
One thing that concerns me is that some places use pci_device_load/save
which does some irq mangling, but others just use the VMSTATE_PCI_DEVICE
macro - how are they getting the same irq mangling?

xhci has a fixed number of 24 (TD_QUEUE) XHCITransfer structs per
endpoint, which turns out to be a problem for usb3 devices with 32 (or
more) bulk streams. xhci re-checks the trb rings on every finished
transfer to make sure it'll pick up any pending work. But that scheme
breaks in case the first transfer of a ring can't be started because we
ran out of XHCITransfer structs already.
So remove static XHCITransfer array from XHCIEPContext. Use a linked
list instead, and allocate/free XHCITransfer as needed. Add helper
functions to allocate & initialize and to cleanup & release
XHCITransfer structs. That also simplifies trb management, we never
have to realloc XHCITransfer->trbs because we don't reuse XHCITransfer
structs any more.
New dynamic limit for in-flight xhci transfers per endpoint is
number-of-streams + 16.

This patch is a rough fix to a memory corruption we are observing when
running VMs with xhci USB controller and OVMF firmware.
Specifically, on the following call chain
xhci_reset
xhci_disable_slot
xhci_disable_ep
xhci_set_ep_state
QEMU overwrites guest memory using stale guest addresses.
This doesn't happen when the guest (firmware) driver sets up xhci for
the first time as there are no slots configured yet. However when the
firmware hands over the control to the OS some slots and endpoints are
already set up with their context in the guest RAM. Now the OS' driver
resets the controller again and xhci_set_ep_state then reads and writes
that memory which is now owned by the OS.
As a quick fix, skip calling xhci_set_ep_state in xhci_disable_ep if the
device context base address array pointer is zero (indicating we're in
the HC reset and no DMA is possible).
