0846e6359c xhci: update port handling
This patch changes the way xhci ports are linked to USBPorts.  The fixed
1:1 relationship between xhci ports and USBPorts is gone.  Now each
USBPort represents a physical plug which has usually two xhci ports
assigned: one usb2 and ond usb3 port.  usb devices show up at one or the
other, depending on whenever they support superspeed or not.

This patch also makes the number of usb2 and usb3 ports runtime
configurable by adding 'p2' and 'p3' properties.  It is allowed to
have different numbers of usb2 and usb3 ports.  Specifying p2=4,p3=2
will give you an xhci adapter which supports all speeds on physical
ports 1+2 and usb2 only on ports 3+4.

d5a15814b4 xhci: drop buffering
This patch splits the xhci_xfer_data function into three.
The xhci_xfer_data function used to do does two things:

  (1) copy transfer data between guest memory and a temporary buffer.
  (2) report transfer results to the guest using events.

Now we three functions to handle this:

  (1) xhci_xfer_map creates a scatter list for the transfer and
      uses that (instead of the temporary buffer) to build a
      USBPacket.
  (2) xhci_xfer_unmap undoes the mapping.
  (3) xhci_xfer_report sends out events.

The patch also fixes reporting of transaction errors which must be
reported unconditinally, not only in case the guest asks for it
using the ISP flag.

331e9406f1 xhci: rip out background transfer code
original xhci code (the one which used libusb directly) used to use
'background transfers' for iso streams.  In upstream qemu the iso
stream buffering is handled by usb-host & usb-redir, so we will
never ever need this.  It has been left in as reference, but is dead
code anyway.  Rip it out.

104981d52b usb-redir: Get rid of local shadow copy of packet headers
The shadow copy only serves as an extra check (besides the packet-id) to
ensure the packet we get back is a reply to the packet we think it is.

This check has never triggered in all the time usb-redir is in use now,
and since the verified data in the returned packet-header is not used
otherwise, removing the check does not open any possibilities for the
usbredirhost to confuse us.

This is a preparation patch for completely getting rid of the async-packet
struct in usb-redir, instead relying on the (new) per ep queues in the

that we also properly cleanup a NAK-ed packet on cancel.

66f092d256 Revert "ehci: don't flush cache on doorbell rings."
This reverts commit 9bc3a3a216, which got
added to fix an issue where the real, underlying cause was not stopping
the ep queue on an error.

Now that the underlying cause is fixed by the "usb: Halt ep queue and
cancel pending packets on a packet error" patch, the "don't flush" fix
is no longer needed.

Not only is it not needed, it causes us to see cancellations (unlinks)
done by the Linux EHCI driver too late, which in combination with the new
usb-core packet-id generation where qtd addresses are used as ids, causes
duplicate ids for in flight packets.

45b339b18c usb: controllers do not need to check for babble themselves
If an (emulated) usb-device tries to write more data to a packet then
its iov len, this will trigger an assert in usb_packet_copy(), and if
a driver somehow circumvents that check and writes more data to the
iov then there is space, we have a much bigger problem then not correctly
reporting babble to the guest.

In practice babble will only happen with (real) redirected devices, and there
both the usb-host os and the qemu usb-device code already check for it.

56038ef623 RTC: Update the RTC clock only when reading it
Calculate guest RTC based on the time of the last update, instead of
using timers.  The formula is

    (base_rtc + guest_time_now - guest_time_last_update + offset)

Base_rtc is the RTC value when the RTC was last updated.
Guest_time_now is the guest time when the access happens.
Guest_time_last_update was the guest time when the RTC was last updated.
Offset is used when divider reset happens or the set bit is toggled.

The timer is kept in order to signal interrupts, but it only needs to
run when either UF or AF is cleared.  When the bits are both set, the
timer does not run.

UIP is now synthesized when reading register A.  If the timer is not set,
or if there is more than one second before it (as is the case at the
end of this series), the leading edge of UIP is computed and the rising
edge occurs 220us later.  If the update timer occurs within one second,
however, the rising edge of the AF and UF bits should coincide withe
the falling edge of UIP.  We do not know exactly when this will happen
because there could be delays in the servicing of the timer.  Hence, in
this case reading register A only computes for the rising edge of UIP,
and latches the bit until the timer is fired and clears it.

c3ebd3ba78 kvm: i386: Add classic PCI device assignment
This adds PCI device assignment for i386 targets using the classic KVM
interfaces. This version is 100% identical to what is being maintained
in qemu-kvm for several years and is supported by libvirt as well. It is
expected to remain relevant for another couple of years until kernels
without full-features and performance-wise equivalent VFIO support are
obsolete.

A refactoring to-do that should be done in-tree is to model MSI and
MSI-X support via the generic PCI layer, similar to what VFIO is already
doing for MSI-X. This should improve the correctness and clean up the
code from duplicate logic.

1de5345927 pcie: drop version_id field for live migration
While testing q35 live migration, I found that the migration would abort with
the following error: "Unknown savevm section type 76".

The error is due to this check failing in 'vmstate_load_state()':

    while(field->name) {
        if ((field->field_exists &&
             field->field_exists(opaque, version_id)) ||
            (!field->field_exists &&
             field->version_id <= version_id)) {

The VMSTATE_PCIE_DEVICE() currently has a 'version_id' set to 2. However,
'version_id' in the above check is 1. And thus we fail to load the pcie device
field. Further the code returns to 'qemu_loadvm_state()' which produces the
error that I saw.

I'm proposing to fix this by simply dropping the 'version_id' field from
VMSTATE_PCIE_DEVICE(). VMSTATE_PCI_DEVICE() defines no such field and further
the vmstate_pcie_device that VMSTATE_PCI_DEVICE() refers to is already
versioned. Thus, any versioning issues could be detected at the vmsd level.

Taking a step back, I think that the 'field->version_id' should be compared
against a saved version number for the field not the 'version_id'. Futhermore,
once vmstate_load_state() is called recursively on another vmsd, the check of:

    if (version_id > vmsd->version_id) {
        return -EINVAL;
    }

Will never fail since version_id is always equal to vmsd->version_id. So I'm
wondering why we aren't storing the vmsd version id of the source in the
migration stream?

This patch also renames the 'name' field of vmstate_pcie_device from:
PCIDevice -> PCIEDevice to differentiate it from vmstate_pci_device.

a1c3e4b839 ehci: Schedule async-bh when IAAD bit gets set
After the "ehci: Print a warning when a queue unexpectedly contains packets
on cancel" commit. Under certain reproducable conditions I was getting the
following message: "EHCI: Warning queue not empty on queue reset".

After aprox. 8 hours of debugging I've finally found the cause. The Linux EHCI
driver has an IAAD watchdog, to work around certain EHCI hardware sometimes
not acknowledging the doorbell at all. This watchdog has a timeout of 10 ms,
which is less then the time between 2 runs through the async schedule when
async_stepdown is at its highest value.

Thus the watchdog can trigger, after which Linux clears the IAAD bit and
re-uses the QH. IOW we were not properly detecting the unlink of the qh, due
to us missing (ignoring for more then 10 ms) the IAAD command, which triggered
the warning.

e983395d30 usb: unique packet ids
This patch adds IDs to usb packets.  Those IDs are (a) supposed to be
unique for the lifecycle of a packet (from packet setup until the packet
is either completed or canceled) and (b) stable across migration.

uhci, ohci, ehci and xhci use the guest physical address of the transfer
descriptor for this.

musb needs a different approach because there is no transfer descriptor.
But musb also doesn't support pipelining, so we have never more than one
packet per endpoint in flight.  So we go create an ID based on endpoint
and device address.

0132b4b659 usb: Halt ep queue en cancel pending packets on a packet error
For controllers which queue up more then 1 packet at a time, we must halt the
ep queue, and inside the controller code cancel all pending packets on an
error.

There are multiple reasons for this:
1) Guests expect the controllers to halt ep queues on error, so that they
get the opportunity to cancel transfers which the scheduled after the failing
one, before processing continues

2) Not cancelling queued up packets after a failed transfer also messes up
the controller state machine, in the case of EHCI causing the following
assert to trigger: "assert(p->qtdaddr == q->qtdaddr)" at hcd-ehci.c:2075

3) For bulk endpoints with pipelining enabled (redirection to a real USB
device), we must cancel all the transfers after this a failed one so that:
a) If they've completed already, they are not processed further causing more
   stalls to be reported, originating from the same failed transfer
b) If still in flight, they are cancelled before the guest does
   a clear stall, otherwise the guest and device can loose sync!

Note this patch only touches the ehci and uhci controller changes, since AFAIK
no other controllers actually queue up multiple transfer. If I'm wrong on this
other controllers need to be updated too!

Also note that this patch was heavily tested with the ehci code, where I had
a reproducer for a device causing a transfer to fail. The uhci code is not
tested with actually failing transfers and could do with a thorough review!
