5007c940a9 uas: s/ui/iu/
The various uas data structures are called IU-s, which is short for
Information Unit, rather then UI-s.

49cfa2fdc9 uas: Fix response iu struct definition
This patch mirrors a patch to the Linux uas kernel driver which I've just
submitted. It looks like the qemu uas struct definitions were taken from
the Linux kernel driver, and have inherited the same mistake.

Besides fixing the response iu struct, the patch also drops the add_info
parameter from the usb_uas_queue_response() function, it is always 0 anyways,
and expressing 3 zero-bytes as a function argument is a bit hard.

Below is the long explanation for this change taken from the kernel commit:

The response iu struct before this patch has a size of 7 bytes, which is weird
since all other iu-s are explictly padded to a multiple of 4 bytes.

Submitting a 7 byte bulk transfer to the status endpoint of a real uasp device
when expecting a response iu results in an USB babble error, as the device
actually sends 8 bytes.

Up on closer reading of the UAS spec:
http://www.t10.org/cgi-bin/ac.pl?t=f&f=uas2r00.pdf

The reason for this becomes clear, the 2 entries in "Table 17 — RESPONSE IU"
are numbered 4 and 6, looking at other iu definitions in the spec, esp.
multi-byte fields, this indicates that the ADDITIONAL RESPONSE INFORMATION
field is not a 2 byte field as one might assume at a first look, but is
a multi-byte field containing 3 bytes.

This also aligns with the SCSI Architecture Model 4 spec, which UAS is based
on which states in paragraph "7.1 Task management function procedure calls"
that the "Additional Response Information" output argument for a Task
management function procedure call is 3 bytes.

Last but not least I've verified this by sending a logical unit reset task
management call with an invalid lun to an actual uasp device, and received
back a response-iu with byte 6 being 0, and byte 7 being 9, which is the
responce code for an invalid iu, which confirms that the response code is
being reported in byte 7 of the response iu rather then in byte 6.

5eb6d9e3ef uas: Fix / cleanup usb_uas_task error handling
-The correct error if we cannot find the dev is INCORRECT_LUN rather then
 INVALID_INFO_UNIT
-Move the device not found check to the top so we only need to do it once
-Remove the dev->lun != lun checks, dev is returned by scsi_device_find

f1f8bc218a xhci: add support for suspend/resume
The OS can ask the xhci controller to save and restore its
internal state, which is used by the OS when the system is
suspended and resumed.

This patch handles writes to the save + restore bits in the
command register.  Only thing it does is updating the
restore error bit in the status register to signal an error
on restore.  The guest OS should do a full reinitialization
after resume then.

This is the minimal patch which gets S3 going with xhci.
Implementing full save/restore support is TBD.

de9de157fb xhci: Add a few missing checks for disconnected devices
One of the reworks of qemu's usb core made changes to usb-port's disconnect
handling. Now ports with a device will always have a non 0 dev member, but
if the device is not attached (which is possible with usb redirection),
dev->attached will be 0.

So supplement all checks for dev to also check dev->attached, and add an
extra check in a path where a device check was completely missing.

This fixes various crashes (asserts triggering) I've been seeing when xhci
attached usb devices get disconnected at the wrong time.

02a5c4c974 qdev: Drop misleading qdev_free() function
The qdev_free() function name is misleading since all the function does
is unlink the device from its parent.  The device is not necessarily
freed.

The device will be freed when its QObject refcount reaches zero.  It is
usual for the parent (bus) to hold the final reference but there are
cases where something else holds a reference so "free" is a misleading
name.

Call object_unparent(obj) directly instead of having a qdev wrapper
function.

At least Linux guests expect it to point to value set by an set_ep_dequeue

Otherwise the Linux kernel will complain (and things won't work):

	Note that some devices, in violation of the USB spec, have a
	configuration with a value equal to 0. Writing 0 to
	bConfigurationValue for these devices will install that
	configuration, rather then unconfigure the device.

So don't compare the configuration value against 0 to check for unconfigured
devices, instead check for a LIBUSB_ERROR_NOT_FOUND return from
libusb_get_active_config_descriptor().

5af35d7fec usb-host-libusb: Fix reset handling
The guest will issue an initial device reset when the device is attached, but
since the current usb-host-libusb code only actually does the reset when
udev->configuration != 0, and on attach the device is not yet configured,
the reset gets ignored. This means that the device gets passed to the guest
in an unknown state, which is not good.

The udev->configuration check is there because of the release / claim
interfaces done around the libusb_device_reset call, but these are not
necessary. If interfaces are claimed when libusb_device_reset gets called
libusb will release + reclaim them itself.

The usb_host_ep_update call also is not necessary. If the reset succeeds the
original config and interface alt settings will be restored.

Last if the reset fails, that means the device has either disconnected or
morphed into an another device and has been completely re-enumerated,
so it is treated by the host as a new device and our handle is invalid,
so on reset failure we need to call usb_host_nodev().

cf66ee8e20 hcd-ohci: add dma error handling
Current hcd-ohci does not handle DMA errors. However they may happen
so here we introduce simple error handling.

On such errors, a typical OHCI will stop operating, signal the guest
about the error by sending "UnrecoverableError Event", set itself into
error state and set "Detected Parity Error" in its PCI config space
to signal that it got an error and so does the patch.

This also adds ohci_die() call to ohci_bus_start() to handle possible
failure of qemu_new_timer_ns().

6783ecf144 hw: Avoid use of QOM type name macros in VMStateDescriptions

bad idea to use a QOM typename macro to initialize it, because in
general we're free to rename QOM types as part of code refactoring
and cleanup.  For the handful of devices that were doing this by
mistake, replace the QOM typenames with the corresponding literal
strings.

9822261ce3 uhci: Use an intermediate buffer for usb packet data
Due to various unfortunate reasons we cannot reliable detect a guest
cancelling a packet as soon as it happens, instead we detect cancels
with some delay.

When packets are handled async, and we directly pass the guest memory for
the packet to the usb-device as iovec, this means that the usb-device can
write to guest-memory which the guest has already re-used for other purposes
-> not good!

This patch fixes this by adding an intermediate buffer and writing back not
only the result, but also the data, of async completed packets when scanning
the schedule.
