commit 33cd52b5d7 unset
cannot_instantiate_with_device_add_yet in TYPE_SYSBUS, making all
sysbus devices appear on "-device help" and lack the "no-user"
flag in "info qdm".
To fix this, we can set user_creatable=false by default on
TYPE_SYS_BUS_DEVICE, but this requires setting
user_creatable=true explicitly on the sysbus devices that
actually work with -device.
Fortunately today we have just a few has_dynamic_sysbus=1
machines: virt, pc-q35-*, ppce500, and spapr.
virt, ppce500, and spapr have extra checks to ensure just a few
device types can be instantiated:
* virt supports only TYPE_VFIO_CALXEDA_XGMAC, TYPE_VFIO_AMD_XGBE.
* ppce500 supports only TYPE_ETSEC_COMMON.
* spapr supports only TYPE_SPAPR_PCI_HOST_BRIDGE.
This patch sets user_creatable=true explicitly on those 4 device
classes.
Now, the more complex cases:
pc-q35-*: q35 has no sysbus device whitelist yet (which is a
separate bug). We are in the process of fixing it and building a
sysbus whitelist on q35, but in the meantime we can fix the
"-device help" and "info qdm" bugs mentioned above. Also, despite
not being strictly necessary for fixing the q35 bug, reducing the
list of user_creatable=true devices will help us be more
confident when building the q35 whitelist.
xen: We also have a hack at xen_set_dynamic_sysbus(), that sets
has_dynamic_sysbus=true at runtime when using the Xen
accelerator. This hack is only used to allow xen-backend devices
to be dynamically plugged/unplugged.
This means today we can use -device with the following 22 device
types, that are the ones compiled into the qemu-system-x86_64 and
qemu-system-i386 binaries:
* allwinner-ahci
* amd-iommu
* cfi.pflash01
* esp
* fw_cfg_io
* fw_cfg_mem
* generic-sdhci
* hpet
* intel-iommu
* ioapic
* isabus-bridge
* kvmclock
* kvm-ioapic
* kvmvapic
* SUNW,fdtwo
* sysbus-ahci
* sysbus-fdc
* sysbus-ohci
* unimplemented-device
* virtio-mmio
* xen-backend
* xen-sysdev
This patch adds user_creatable=true explicitly to those devices,
temporarily, just to keep 100% compatibility with existing
behavior of q35. Subsequent patches will remove
user_creatable=true from the devices that are really not meant to
user-creatable on any machine, and remove the FIXME comment from
the ones that are really supposed to be user-creatable. This is
being done in separate patches because we still don't have an
obvious list of devices that will be whitelisted by q35, and I
would like to get each device reviewed individually.

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
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

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.

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.

CCID device emulator uses Application Protocol Data Units(APDU)
to exchange command and responses to and from the host.
The length in these units couldn't be greater than 65536. Add
check to ensure the same. It'd also avoid potential integer
overflow in emulated_apdu_from_guest.

xhci_submit and xhci_fire_ctl_transfer are is called from
xhci_kick_epctx processing loop only, so there is no need to call
xhci_kick_epctx make sure processing continues. Also eecursive calls
into xhci_kick_epctx can cause trouble.
Drop the xhci_kick_epctx calls.

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
some of the new instructions.
* Revise a number of qtests and enable them for ppc

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.

usb_xhci_realize() corrects invalid values of property "intrs"
automatically, but the uncorrected value is passed to msi_init(),
which chokes on invalid values. Delay that until after the
correction.
Resources allocated by usb_xhci_init() are leaked when msi_init()
fails. Fix by calling it after msi_init().
