When trying to build with latest libcacard-2.5.1, I hit the
following error:
In file included from hw/usb/ccid-card-passthru.c:12:0:
/usr/include/cacard/vscard_common.h:26:2: error: #warning "Only <libcacard.h> can be included directly" [-Werror=cpp]
#warning "Only <libcacard.h> can be included directly"
While it was fixed in libcacard upstream (so that individual
files can be included directly), it doesn't make much sense.
Let's switch to including the main libcacard.h and also require
at least libcacard-2.5.1 which introduced it. It's available
since late 2015.

precursor to write is the sending of the write metadata

The option have been marked as deprecated since QEMU 2.10, and so far
nobody complained that the host, serial, disk and net options are urgently
required anymore. So let's now get rid at least of this legacy pile, to
simplify the usb code quite a bit.
This patch removes the usbdevices host, serial, disk and net. These devices
use their own complicated parameter parsing mechanisms, so they are just
ugly to maintain, without real benefit for the users (the users can use the
corresponding "-device" parameters instead which have the same complexity
as the "-usbdevice" devices here).
Note that the other rather simple -usbdevice options (mouse, tablet, etc.)
are not removed yet (the code is really simple here, so it does not hurt
much to keep it), as well as the two devices "braille" and "bt" which are
easier to use with -usbdevice than with -device.

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.

Add INTERFACE_CONVENTIONAL_PCI_DEVICE to all direct subtypes of
TYPE_PCI_DEVICE, except:
1) The ones that already have INTERFACE_PCIE_DEVICE set:
* base-xhci
* e1000e
* nvme
* pvscsi
* vfio-pci
* virtio-pci
* vmxnet3
2) base-pci-bridge
Not all PCI bridges are Conventional PCI devices, so
INTERFACE_CONVENTIONAL_PCI_DEVICE is added only to the subtypes
that are actually Conventional PCI:
* dec-21154-p2p-bridge
* i82801b11-bridge
* pbm-bridge
* pci-bridge
The direct subtypes of base-pci-bridge not touched by this patch
are:
* xilinx-pcie-root: Already marked as PCIe-only.
* pcie-pci-bridge: Already marked as PCIe-only.
* pcie-port: all non-abstract subtypes of pcie-port are already
marked as PCIe-only devices.
3) megasas-base
Not all megasas devices are Conventional PCI devices, so the
interface names are added to the subclasses registered by
megasas_register_types(), according to information in the
megasas_devices[] array.
"megasas-gen2" already implements INTERFACE_PCIE_DEVICE, so add
INTERFACE_CONVENTIONAL_PCI_DEVICE only to "megasas".

Modify the pre_save method on VMStateDescription to return an int
rather than void so that it potentially can fail.
Changed zillions of devices to make them return 0; the only
case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already
had an error_report/return case.
Note: If you add an error exit in your pre_save you must emit
an error_report to say why.

Code that checks dstate is unaware of SystemTap and LTTng UST dstate, so
the following trace event will not fire when solely enabled by SystemTap

if (trace_event_get_state(TRACE_MY_EVENT)) {
str = g_strdup_printf("Expensive string to generate ...",

Add trace_event_get_state_backends() to fetch backend dstate. Those

trace_event_get_state_backends() instead.

But we know that there are at most 5 levels of USB hubs, with at
most two digits per level; that plus the separating dots means we
use at most 15 bytes (including trailing NUL) of our 16-byte field.
Adding an assertion to show gcc that we checked for truncation is
enough to shut up the false-positive warning.

In some cases a failing VMSTATE_*_EQUAL does not mean we detected a bug,
but it's actually the best we can do. Especially in these cases a verbose
error message is required.
Let's introduce infrastructure for specifying a error hint to be used if
equal check fails. Let's do this by adding a parameter to the _EQUAL
macros called _err_hint. Also change all current users to pass NULL as
last parameter so nothing changes for them.

Some USB devices have sparse interface numbering which is not able to be
passthroughed.
For example, the Sierra Wireless MC7455/MC7430:
# lsusb -D /dev/bus/usb/003/003 | egrep '1199|9071|bNumInterfaces|bInterfaceNumber'
Device: ID 1199:9071 Sierra Wireless, Inc.
idVendor 0x1199 Sierra Wireless, Inc.
idProduct 0x9071
bNumInterfaces 5
bInterfaceNumber 0
bInterfaceNumber 2
bInterfaceNumber 3
bInterfaceNumber 8
bInterfaceNumber 10
In this case, the interface numbers are 0, 2, 3, 8, 10 and not the
0, 1, 2, 3, 4 that QEMU tries to claim.
This change allows sparse USB interface numbering.
Instead of only claiming the interfaces in the range reported by the USB
device through bNumInterfaces, QEMU attempts to claim all possible
interfaces.

we will not pick them up again after migration, which easily

ehci registers ehci_frame_timer as both timer and bottom half, which
turned out to be a bad idea as it can be called as bottom half then
while it is running as timer, and it isn't prepared to handle recursive
calls.
Change the timer func to just schedule the bottom half to avoid this.

PORT_STAT_C_SUSPEND should be set even on host-initiated wake-up,
i.e. on ClearPortFeature(PORT_SUSPEND). Windows is known to not
work properly otherwise.
Side note, since PORT_ENABLE looks similar and might appear to
have the same issue: According to 11.24.2.7.2.2 C_PORT_ENABLE:
"This bit is set when the PORT_ENABLE bit changes from one to
zero as a result of a Port Error condition (see Section 11.8.1).
This bit is not set on any other changes to PORT_ENABLE."

The spec says:
Suspend: (PORT_SUSPEND) This field indicates whether or not the device
on this port is suspended. Setting this field causes the device to
suspend by not propagating bus traffic downstream. This field may be
reset by a request or by resume signaling from the device attached to
the port.
I can't find any specific statement like "the PORT_SUSPEND field is reset
automatically on remote wakeup", but without this patch, the only way to
reset it is via the ClearPortFeature request so the ".. or by resume
signaling from the device" clause is clearly not implemented on the remote
wakeup path.
The default xhci Windows driver does not issue the ClearPortFeature request
and suspended devices attached to a hub don't properly get out of the
suspended state. Interestingly, the default uhci Windows driver *does*
issue the ClearPortFeature request and does not exhibit this problem.

When done processing a endpoint ring we must update the dequeue pointer

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.

1. Set bInterfaceProtocol to 0x00 for usb-tablet. This should be
non-zero for boot protocol devices only, which the usb-tablet is not.
2. Set the usb-tablet's usage to "mouse" in the report descriptor.
The boot protocol of 0x02 specifically confused OS X/macOS' HID driver
stack, causing it to generate additional bogus HID events with relative
motion in addition to the tablet's absolute coordinate events.
Absolute pointing devices with HID Report Descriptor usage of 0x01
(pointing) are treated by the macOS HID driver as analog sticks, and
absolute coordinates are not directly translated to absolute mouse
cursor positions. Changing it to 0x02 (mouse) fixes the problem, and
does not have any adverse effect in other operating systems and
windowing systems. (VMWare does the same thing.)

This obsoletes ppc-for-2.9-20170112, which had a MacOS build bug.
This is a long overdue ppc pull request for qemu-2.9. It's been a
long time coming due to some holidays and inconveniently timed
problems with testing. So, there's a lot in here:
* More POWER9 instruction implementations for TCG
* The simpler parts of my CPU compatibility mode cleanup
* This changes behaviour to prefer compatibility modes over
"raW" mode for new machine type versions
* New "40p" machine type which is essentially a modernized and
cleaned up "prep". The intention is that it will replace "prep"
once it has some more testing and polish.
* Add pseries-2.9 machine type
* Implement H_SIGNAL_SYS_RESET hypercall
* Consolidate the two alternate CPU init paths in pseries by
making it always go through CPU core objects to initialize CPU
* A number of bugfixes and cleanups
* Stop the guest timebase when the guest is stopped under KVM.
This makes the guest system clock also stop when paused, which
matches the x86 behaviour.
* Some preliminary cleanups leading towards implementation of the
POWER9 MMU.
There are also some changes not strictly related to ppc code, but for
its benefit:
* Limit the pxi-expander-bridge (PXB) device to x86 guests only
(it's essentially a hack to work around historical x86
limitations)
* Some additions to the 128-bit math in host_utils, necessary for

msix_init() reports errors with error_report(), which is wrong when
it's used in realize(). The same issue was fixed for msi_init() in
commit 1108b2f. In order to make the API change as small as possible,
leave the return value check to later patch.
For some devices(like e1000e, vmxnet3, nvme) who won't fail because of
msix_init's failure, suppress the error report by passing NULL error
object.
Bonus: add comment for msix_init.

When passing through an USB storage device to a pseries guest, it
is currently not possible to automatically boot from the device
if the "bootindex" property has been specified, too (e.g. when using
"-device nec-usb-xhci -device usb-host,hostbus=1,hostaddr=2,bootindex=0"
at the command line). The problem is that QEMU builds a device tree path
like "/pci@800000020000000/usb@0/usb-host@1" and passes it to SLOF
in the /chosen/qemu,boot-list property. SLOF, however, probes the
USB device, recognizes that it is a storage device and thus changes
its name to "storage", and additionally adds a child node for the
SCSI LUN, so the correct boot path in SLOF is something like
"/pci@800000020000000/usb@0/storage@1/disk@101000000000000" instead.
So when we detect an USB mass storage device with SCSI interface,
we've got to adjust the firmware boot-device path properly that
SLOF can automatically boot from the device.

The vmstate_pci_device and vmstate_pcie_devices differ
just in the size of one buffer; combine the two using a _TEST
macro.
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?
This passes a smoke test migrate of:

The default DMA offset is set to 3. When the property is not set by
the consumer, the default causes DMA access to be shifted by 3
bytes. In PXA, this results in incorrect DMA access, leading to error

0, so that there is no offset, when the consumer does not specify one.

snprintf return value is *not* the number of chars written into the
buffer, but the number of chars needed. So in case the buffer is too
small you can go alloc a bigger one and try again. But that also means
you can't simply use the return value for the next snprintf call
without checking beforehand that things did actually fit.
Problem is that usb_desc_create_serial didn't perform that check, so a
loooong path string (can happen with deep pci-bridge nesting) results in
the third snprintf call smashing the stack.
Fix this by throwing out all the snpintf calls and use g_strdup_printf
instead.

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.

Windows uses object properties to determine the size of a file, so to
add object properties, we must also add a minimum set of new commands
and object properties. Most object properties are data that we already
have, except for the unique persistant object identifier. Windows
doesn't use this property, it seems, so we can cheat a bit and just use
the object handle for it.

The qemu_chr_fe_write method will return -1 on EAGAIN if the
chardev backend write would block. Almost no callers of the
qemu_chr_fe_write() method check the return value, instead
blindly assuming data was successfully sent. In most cases
this will lead to silent data loss on interactive consoles,
but in some cases (eg RNG EGD) it'll just cause corruption
of the protocol being spoken.
We unfortunately can't fix the virtio-console code, due to
a bug in the Linux guest drivers, which would cause the
entire Linux kernel to hang if we delay processing of the
incoming data in any way. Fixing this requires first fixing
the guest driver to not hold spinlocks while writing to the
hvc device backend.

ehci_update_frindex takes time linearly proportional to a number
of uframes to calculate new frame index and raise FLR interrupts,
which is a problem for large amounts of uframes.
If we experience large delays between echi timer callbacks (i.e. because
other periodic handlers have taken a lot of time to complete) we
get a lot of skipped frames which then delay ehci timer callback more
and this leads to deadlocking the system when ehci schedules next
callback to be too soon.
Observable behaviour is qemu consuming 100% host CPU time while guest
is unresponsive. This misbehavior could happen for a while and QEMU does
not get out from this state automatically without the patch.
This change makes ehci_update_frindex execute in constant time.

This is a mostly-mechanical conversion that creates a new flat
union 'Netdev' QAPI type that covers all the branches of the
former 'NetClientOptions' simple union, where the branches are
now listed in a new 'NetClientDriver' enum rather than generated
from the simple union. The existence of a flat union has no
change to the command line syntax accepted for new code, and
will make it possible for a future patch to switch the QMP
command to parse a boxed union for no change to valid QMP; but
it does have some ripple effect on the C code when dealing with
the new types.
While making the conversion, note that the 'NetLegacy' type
remains unchanged: it applies only to legacy command line options,
and will not be ported to QMP, so it should remain a wrapper
around a simple union; to avoid confusion, the type named
'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions'
in its place. Then, in the C code, we convert from NetLegacy to
Netdev as soon as possible, so that the bulk of the net stack
only has to deal with one QAPI type, not two. Note that since
the old legacy code always rejected 'hubport', we can just omit
that branch from the new 'NetLegacyOptions' simple union.

As cache.writeback is a BlockBackend property and as such more related

from the blockdev-add interface. This patch adds the new way to set it,

If a node name instead of a BlockBackend name is specified as the driver
for a guest device, an anonymous BlockBackend is created now.
The order of operations in release_drive() must be reversed in order to
avoid a use-after-free bug because now blk_detach_dev() frees the last
reference if an anonymous BlockBackend is used.
usb-storage uses a hack where it forwards its BlockBackend as a property
to another device that it internally creates. This hack must be updated
so that it doesn't drop its original BB before it can be passed to the
other device. This used to work because we always had the monitor
reference around, but with node-names the device reference is the only
one now.
