Remove the "default y" for USB_XHCI_SYSBUS because
sysbus devices are not user creatable; boards that use them will
specify them manually with "imply" or "select" clauses.
It would be nice to keep the ability to remove PCIe and USB from microvm,
since thos can be disabled on the command line and therefore should not
be included if QEMU is configured --without-default-devices. However
it's too late for 5.2 to figure out a place for the DSDT creation code.

Some operating systems will generate a new device ID when a USB device is unplugged
and then replugged into the USB. If this is done whilst switching between multiple
applications over a virtual serial port, the change of device ID requires going
back into the OS/application to locate the new device accordingly.
Add a new always-plugged property that if specified will ensure that the device
always remains attached to the USB regardless of the state of the backend

The NPCM730 and NPCM750 chips have a single USB host port shared between
a USB 2.0 EHCI host controller and a USB 1.1 OHCI host controller. This
adds support for both of them.
Testing notes:
* With -device usb-kbd, qemu will automatically insert a full-speed
hub, and the keyboard becomes controlled by the OHCI controller.
* With -device usb-kbd,bus=usb-bus.0,port=1, the keyboard is directly
attached to the port without any hubs, and the device becomes
controlled by the EHCI controller since it's high speed capable.
* With -device usb-kbd,bus=usb-bus.0,port=1,usb_version=1, the
keyboard is directly attached to the port, but it only advertises
itself as full-speed capable, so it becomes controlled by the OHCI
controller.
In all cases, the keyboard device enumerates correctly.

The EHCI Host Controller emulation attempt to locate the device
associated with a periodic isochronous transfer description (iTD) and
when this fail the host controller is reset.
But according the EHCI spec 1.0 section 5.15.2.4 Host System
Error, the host controller is supposed to reset itself only when it
failed to communicate with the Host (Operating System), like when
there's an error on the PCI bus. If a transaction fails, there's
nothing in the spec that say to reset the host controller.
This patch rework the error path so that the host controller can keep
working when the OS setup a bogus transaction, it also revert to the
behavior of the EHCI emulation to before commits:
e94682f1fe ("ehci: check device is not NULL before calling usb_ep_get()")
7011baece2 ("usb: remove unnecessary NULL device check from usb_ep_get()")
The issue has been found while trying to passthrough a USB device to a
Windows Server 2012 Xen guest via "usb-ehci", which prevent the USB
device from working in Windows. ("usb-ehci" alone works, windows only
setup this weird periodic iTD to device 127 endpoint 15 when the USB
device is passthrough.)

* include/hw/xen/xen_common.h trace points are in hw/xen/trace-events.
* linux-user/trace-events abbreviates a tedious list of filenames to

Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.
Patch generated using:
$ ./scripts/codeconverter/converter.py -i \
--pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')
which will split "typdef struct { ... } TypedefName"
declarations.
Followed by:
$ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
$(git grep -l '' -- '*.[ch]')
which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

This patch adds the U2F key emulated mode.
The emulated mode consists of completely emulating the behavior of a
U2F device through software part. Libu2f-emu is used for that.
The emulated mode is associated with a device inheriting from
u2f-key base.
To work, an emulated U2F device must have differents elements which
can be given in different ways. This is detailed in docs/u2f.txt.
The Ephemeral one is the simplest way to configure, it lets the device
generate all the elements it needs for a single use of the lifetime
of the device:
qemu -usb -device u2f-emulated

This patch adds the U2F key pass-through mode.
The pass-through mode consists of passing all requests made from the
guest to the physical security key connected to the host machine and
vice versa.
In addition, the dedicated pass-through allows to have a U2F security key
shared on several guests which is not possible with a simple host device
assignment pass-through.
The pass-through mode is associated with a device inheriting from
u2f-key base.
To work, it needs the path to a U2F hidraw, obtained from the Qemu
command line, and passed by the user:
qemu -usb -device u2f-passthru,hidraw=/dev/hidrawX
Autoscan and U2F compatibility checking features are given at the end

This patch adds the U2F key base class implementation.
The U2F key base mainly takes care of the HID interfacing with guest.
On the one hand, it retrieves the guest U2FHID packets and transmits
them to the variant associated according to the mode: pass-through
or emulated.
On the other hand, it provides the public API used by its variants to
send U2FHID packets to the guest.

Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path. In particular the tracing headers are using
$(build_root)/$(<D).
In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".
This patch is too ugly to be applied to the Makefiles now. It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

QEMU XHCI advertises AC64 (64-bit addressing) but doesn't allow
64-bit mode access in "runtime" and "operational" MemoryRegionOps.
Set the max_access_size based on sizeof(dma_addr_t) as AC64 is set.
XHCI specs:
"If the xHC supports 64-bit addressing (AC64 = ‘1’), then software
should write 64-bit registers using only Qword accesses. If a
system is incapable of issuing Qword accesses, then writes to the
64-bit address fields shall be performed using 2 Dword accesses;
low Dword-first, high-Dword second. If the xHC supports 32-bit
addressing (AC64 = ‘0’), then the high Dword of registers containing
64-bit address fields are unused and software should write addresses
using only Dword accesses"
The problem has been detected with SLOF, as linux kernel always accesses
registers using 32-bit access even if AC64 is set and revealed by
5d971f9e67 ("memory: Revert "memory: accept mismatching sizes in memory_region_access_valid"")

qbus_set_hotplug_handler() is a simple wrapper around
object_property_set_link().
object_property_set_link() fails when the property doesn't exist, is
not settable, or its .check() method fails. These are all programming
errors here, so passing &error_abort to qbus_set_hotplug_handler() is
appropriate.
Most of its callers do. Exceptions:
* pcie_cap_slot_init(), shpc_init(), spapr_phb_realize() pass NULL,
i.e. they ignore errors.
* spapr_machine_init() passes &error_fatal.
* s390_pcihost_realize(), virtio_serial_device_realize(),
s390_pcihost_plug() pass the error to their callers. The latter two
keep going after the error, which looks wrong.
Drop the @errp parameter, and instead pass &error_abort to

I'm not aware of any immediate bugs in qemu where a second runtime
evaluation of the arguments to MIN() or MAX() causes a problem, but
proactively preventing such abuse is easier than falling prey to an
unintended case down the road. At any rate, here's the conversation
that sparked the current patch:
https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg05718.html
Update the MIN/MAX macros to only evaluate their argument once at
runtime; this uses typeof(1 ? (a) : (b)) to ensure that we are
promoting the temporaries to the same type as the final comparison (we
have to trigger type promotion, as typeof(bitfield) won't compile; and
we can't use typeof((a) + (b)) or even typeof((a) + 0), as some of our
uses of MAX are on void* pointers where such addition is undefined).
However, we are unable to work around gcc refusing to compile ({}) in
a constant context (such as the array length of a static variable),
even when only used in the dead branch of a __builtin_choose_expr(),
so we have to provide a second macro pair MIN_CONST and MAX_CONST for
use when both arguments are known to be compile-time constants and
where the result must also be usable as a constant; this second form
evaluates arguments multiple times but that doesn't matter for
constants. By using a void expression as the expansion if a
non-constant is presented to this second form, we can enlist the
compiler to ensure the double evaluation is not attempted on
non-constants.
Alas, as both macros now rely on compiler intrinsics, they are no
longer usable in preprocessor #if conditions; those will just have to
be open-coded or the logic rewritten into #define or runtime 'if'
conditions (but where the compiler dead-code-elimination will probably
still apply).
I tested that both gcc 10.1.1 and clang 10.0.0 produce errors for all
forms of macro mis-use. As the errors can sometimes be cryptic, I'm
demonstrating the gcc output:
Use of MIN when MIN_CONST is needed:

Fix the resulting callsites that used #if or computed a compile-time
constant min or max to use the new macros. cpu-defs.h is interesting,
as CPU_TLB_DYN_MAX_BITS is sometimes used as a constant and sometimes
dynamic.
It may be worth improving glib's MIN/MAX definitions to be saner, but
that is a task for another day.

Several block device properties related to blocksize configuration must
be in certain relationship WRT each other: physical block must be no
smaller than logical block; min_io_size, opt_io_size, and
discard_granularity must be a multiple of a logical block.
To ensure these requirements are met, add corresponding consistency
checks to blkconf_blocksizes, adjusting its signature to communicate
possible error to the caller. Also remove the now redundant consistency
checks from the specific devices.

libusb seems to no allways call the completion callback for requests
canceled (which it is supposed to do according to the docs). So add
a limit to avoid qemu waiting forever.

The new property allows to specify usb host device name. Uses standard
qemu_open(), so both file system path (/dev/bus/usb/$bus/$dev on linux)
and file descriptor passing can be used.
Requires libusb 1.0.23 or newer. The hostdevice property is only
present in case qemu is compiled against a new enough library version,
so the presence of the property can be used for feature detection.

usb_try_create_simple() is qdev_try_new() and qdev_realize_and_unref()
with more verbose error messages. Of its two users, one ignores
errors, and the other asserts they are impossible.
Make them use qdev_try_new() and qdev_realize_and_unref() directly,
and eliminate usb_try_create_simple

I'm converting from qdev_create()/qdev_init_nofail() to
qdev_new()/qdev_realize_and_unref(); recent commit "qdev: New
qdev_new(), qdev_realize(), etc." explains why.
USB devices use qdev_create() through usb_create().
Provide usb_new() and usb_realize_and_unref() for converting USB
devices.
