In commit a8bff79e9f we added a definition to hw/virtio/virtio-gpu.h
for VIRTIO_GPU_CAPSET_VIRGL2, as a workaround for it not yet being
in the Linux kernel headers. In commit 77d361b13c we updated our
kernel headers to a version which does define the macro, so we can
now remove our workaround.

The "I" bit in PIO Setup and D2H FISes is exclusively a device concept
and the irqstatus register in the controller does not matter. The SATA
spec says when it should be one; for D2H FISes in practice it is always
set, while the PIO Setup FIS has several subcases that are documented in
the patch.
Also, the PIO Setup FIS interrupt is actually generated _after_ data
has been received.
Someone should probably spend some time reading the SATA specification and
figuring out the more obscure fields in the PIO Setup FIS, but this is enough
to fix SeaBIOS booting from ATAPI CD-ROMs over an AHCI controller.

some users when using --daemonize expect that QEMU will parse CLI options,
initialize VM and only then complete daemonzation by signalling lead
process to exit and start listening on monitor socket. So users treat
parent process exit as sync point to connect to QEMU's monitor.
That however doesn't work when --preconfig options is used, since it
provides monitor before completing daemonization and expects user to
issue exit-preconfig command when additional configuration via monitor
is finished. We also can't move completing daemonization before
preconfig monitor becomes available, since that would imply:
* partially loosing ability to configure QEMU instance in --preconfig
mode since QEMU might drop privileges, chroot and do other things
when daemonization is completed
* lead to loss of error messages in case they would happen after
daemonization
Be proactive now and make options mutually exclusive, so users would
get clear error message instead of waiting for lead process exit
indefinitely before connecting to monitor.
PS:
In case someone would come up with usecase where both options should
be enabled at the same time we could drop this restriction as far
as daemonization point is left where it is now (os_setup_post).

Currently, the HDA device tries to sync itself with the QEMU audio
backend by waiting for the guest driver to handle buffer completion
interrupts. This causes the backend to often read too much data from the
device, as well as running out of data whenever the guest takes too long
to handle the interrupt.
According to the HDA specification, the guest is also not required to
use interrupts, but can also sync itself by polling the LPIB registers.
This patch will introduce high frequency (1000Hz) timers that interface
with the device and allow for much smoother emulation of the LPIB
registers. Since the timing is now provided by these timers, the need
to wait for buffer completion interrupts also ceases.

This is part of topoext support. To keep the compatibility, it is better
we support all the combination of nr_cores and nr_threads currently
supported. By allowing more nr_cores and nr_threads, we might end up with
more nodes than we can actually support with the real hardware. We need to
fix up the node id to make this work. We can achieve this by shifting the
socket_id bits left to address more nodes.

When using '-cpu help' the list of CPUID features is grouped according
to the internal low level CPUID grouping. The data printed results in
very long lines too.
This combines to make it hard for users to read the output and identify
if QEMU knows about the feature they wish to use.
This change gets rid of the grouping of features and treats all flags as
single list. The list is sorted into alphabetical order and the printing

The current list of CPU model names output by "-cpu help" is sorted
alphabetically based on the internal QOM class name. The text that is
displayed, however, uses the CPU model name, which is equivalent to the
QOM class name, minus a suffix. Unfortunately that suffix has an effect
on the sort ordering, for example, causing the various Broadwell
variants to appear reversed:
x86 486
x86 Broadwell-IBRS Intel Core Processor (Broadwell, IBRS)
x86 Broadwell-noTSX-IBRS Intel Core Processor (Broadwell, no TSX, IBRS
x86 Broadwell-noTSX Intel Core Processor (Broadwell, no TSX)
x86 Broadwell Intel Core Processor (Broadwell)
x86 Conroe Intel Celeron_4x0 (Conroe/Merom Class Core 2)
By sorting on the actual CPU model name text that is displayed, the
result is
x86 486
x86 Broadwell Intel Core Processor (Broadwell)
x86 Broadwell-IBRS Intel Core Processor (Broadwell, IBRS)
x86 Broadwell-noTSX Intel Core Processor (Broadwell, no TSX)
x86 Broadwell-noTSX-IBRS Intel Core Processor (Broadwell, no TSX, IBRS)
x86 Conroe Intel Celeron_4x0 (Conroe/Merom Class Core 2)
This requires extra string allocations during sorting, but this is not a
concern given the usage scenario and the number of CPU models that exist.

Since the addition of the -IBRS CPU model variants, the descriptions

Commit 1a9a507b2e "qapi-introspect: Hide type names" added local
variable @jsons to improve sorting, but also removed the sorting. It
was part of a big series that went to v8, and it made sense until v2
or so...
Commit 7d0f982bfb replaced @jsons by @qlits, preserving the
uselessness.
Get rid of it.

This commit removes the PYTHON_UTF8 workaround. The problem with setting
LC_ALL= LANG=C LC_CTYPE=en_US.UTF-8
is that the en_US.UTF-8 locale might not be available. In this case
setting above locales results in build errors even though another UTF-8
locale was originally set [1]. The only stable way of fixing the
encoding problem is by specifying the encoding in Python, like the
previous commit does.

[Commit message tweaked]

Python 2 happily reads UTF-8 files in text mode, but Python 3 requires
either UTF-8 locale or an explicit encoding passed to open(). Commit
d4e5ec877c fixed this by setting the en_US.UTF-8 locale. Falls apart
when the locale isn't be available.
Matthias Maier and Arfrever Frehtes Taifersar Arahesis proposed to use
binary mode instead, with manual conversion from bytes to str. Works,
but opening with an explicit encoding is simpler, so do that.
Since Python 2's open() doesn't support the encoding parameter, we
need to suppress it with a version check.

Flat unions may now have uncovered branches, so it is possible to get rid
of empty types defined for that purpose only.

It often happens that just a few discriminator values imply extra data in
a flat union. Existing checks did not make possible to leave other values
uncovered. Such cases had to be worked around by either stating a dummy
(empty) type or introducing another (subset) discriminator enumeration.
Both options create redundant entities in qapi files for little profit.
With this patch it is not necessary anymore to add designated union
fields for every possible value of a discriminator enumeration.

This new test verifies that qdict_flatten() does not modify a shallow
clone of the given QDict.

In its current form, qdict_flatten() removes all entries from nested
QDicts that are moved to the root QDict. It is completely sufficient to
remove all old entries from the root QDict, however. If the nested
dicts have a refcount of 1, this will automatically delete them, too.
And if they have a greater refcount, we probably do not want to modify
them in the first place.
The latter observation means that it was currently (in general)
impossible to qdict_flatten() a shallowly cloned dict because that would
empty nested QDicts in the original dict as well. This patch changes
this, so you can now use qdict_flatten(qdict_shallow_clone(dict)) to get
a flattened copy without disturbing the original.

The event generator produces an enum, and put it in the last visited
module. It fits better in the main module, since it's the set of all
visited events, from all modules.

The code has a while() loop that always initialized 'end', and
the loop always executes at least once (as evidenced by the assert()
just prior to the loop). But some versions of gcc still complain
that 'end' is used uninitialized, so silence them.
