There are test cases on machine_mips_malta.py and tcg_plugins.py files
where the cpu tag does not correspond to the value actually given to the QEMU
binary. This fixed those tests tags.

This introduces a new feature to the functional tests: automatic setting of
the '-cpu VALUE' option to the created vm if the test is tagged with
'cpu:VALUE'. The 'cpu' property is made available to the test object as well.
For example, for a simple test as:
def test(self):
"""
🥑 tags=cpu:host
"""
self.assertEqual(self.cpu, "host")
self.vm.launch()
The resulting QEMU evocation will be like:
qemu-system-x86_64 -display none -vga none \
-chardev socket,id=mon,path=/var/tmp/avo_qemu_sock_pdgzbgd_/qemu-1135557-monitor.sock \

Avocado allows us to select set of tests using tags.
When wanting to run all tests using a NetBSD guest OS,
it is convenient to have them tagged, add the 'os:netbsd'
tag.
It allows one to run the NetBSD tests with:

Add new tests checking the good behavior of the SMMUv3 protecting
2 virtio pci devices (block and net). We check the guest boots and
we are able to install a package. Different guest configs are tested:
standard, passthrough an strict=0. This is tested with both fedora 31 and
33. The former uses a 5.3 kernel without range invalidation whereas the
latter uses a 5.8 kernel that features range invalidation.

If a guest sends binary data on the serial console, we get:
File "tests/acceptance/avocado_qemu/__init__.py", line 92,
in _console_interaction msg = console.readline().strip()
File "/usr/lib64/python3.8/codecs.py", line 322,
in decode (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa9 in position 2: invalid start byte
Since we use the console with readline(), fix it the easiest
way possible: ignore binary data (all current tests compare
text string anyway).

The tests based on the LinuxTest class give the test writer a ready to
use guest operating system, currently pinned to Fedora 31.
With this change, it's now possible to choose different distros and
versions, similar to how other tags and parameter can be set for the
target arch, accelerator, etc.
One of the reasons for this work, is that some development features
depend on updates on the guest side. For instance the tests on
virtiofs_submounts.py, require newer kernels, and may benefit from
running, say on Fedora 34, without the need for a custom kernel.
Please notice that the pre-caching of the Fedora 31 images done during
the early stages of `make check-acceptance` (before the tests are
actually executed) are not expanded here to cover every new image
added. But, the tests will download other needed images (and cache
them) during the first execution.

Instead of having, by default, the checksum in the tests, and the
definition of tests in the framework, let's keep them together.
A central definition for distributions is available, and it should
allow other known distros to be added more easily.
No behavior change is expected here, and tests can still define
a distro_checksum value if for some reason they want to override
the known distribution information.

The recently-added NBD context qemu:allocation-depth is able to
distinguish between locally-present data (even when that data is
sparse) [shown as depth 1 over NBD], and data that could not be found
anywhere in the backing chain [shown as depth 0]; and the libnbd
project was recently patched to give the human-readable name "absent"
to an allocation-depth of 0. But qemu-img map --output=json predates
that addition, and has the unfortunate behavior that all portions of
the backing chain that resolve without finding a hit in any backing
layer report the same depth as the final backing layer. This makes it
harder to reconstruct a qcow2 backing chain using just 'qemu-img map'
output, especially when using "backing":null to artificially limit a
backing chain, because it is impossible to distinguish between a
QCOW2_CLUSTER_UNALLOCATED (which defers to a [missing] backing file)
and a QCOW2_CLUSTER_ZERO_PLAIN cluster (which would override any
backing file), since both types of clusters otherwise show as
"data":false,"zero":true" (but note that we can distinguish a
QCOW2_CLUSTER_ZERO_ALLOCATED, which would also have an "offset":
listing).
The task of reconstructing a qcow2 chain was made harder in commit
0da9856851 (nbd: server: Report holes for raw images), because prior
to that point, it was possible to abuse NBD's block status command to
see which portions of a qcow2 file resulted in BDRV_BLOCK_ALLOCATED
(showing up as NBD_STATE_ZERO in isolation) vs. missing from the chain
(showing up as NBD_STATE_ZERO|NBD_STATE_HOLE); but now qemu reports
more accurate sparseness information over NBD.
An obvious solution is to make 'qemu-img map --output=json' add an
additional "present":false designation to any cluster lacking an
allocation anywhere in the chain, without any change to the "depth"
parameter to avoid breaking existing clients. The iotests have
several examples where this distinction demonstrates the additional
accuracy.

* Implementation of the new H_RPT_INVALIDATE hypercall
* Virtual Open Firmware for pSeries and pegasos2 machine types.
This is an experimental minimal Open Firmware implementation which
works by delegating nearly everything to qemu itself via a special
hypercall.
* A number of cleanups to the ppc soft MMU code
* Fix to handling of two-level radix mode translations for the
powernv machine type
* Update the H_GET_CPU_CHARACTERISTICS call with newly defined bits.
This will allow more flexible handling of possible future CPU
Spectre-like flaws
* Correctly treat mtmsrd as an illegal instruction on BookE cpus
* Firmware update for the ppce500 machine type

we deprecated the ability to create a file with a backing image that

ability to create such images, due to the potential security risk they
present. Update a couple of iotests affected by the change.

Without the allow_other mount option, no user (not even root) but the
one who started qemu/the storage daemon can access the export. Allow
users to configure the export such that such accesses are possible.
While allow_other is probably what users want, we cannot make it an
unconditional default, because passing it is only possible (for non-root
users) if the global fuse.conf configuration file allows it. Thus, the
default is an 'auto' mode, in which we first try with allow_other, and
then fall back to without.
FuseExport.allow_other reports whether allow_other was actually used as
a mount option or not. Currently, this information is not used, but a
future patch will let this field decide whether e.g. an export's UID and
GID can be changed through chmod.
One notable thing about 'auto' mode is that libfuse may print error
messages directly to stderr, and so may fusermount (which it executes).
Our export code cannot really filter or hide them. Therefore, if 'auto'
fails its first attempt and has to fall back, fusermount will print an
error message that mounting with allow_other failed.
This behavior necessitates a change to iotest 308, namely we need to
filter out this error message (because if the first attempt at mounting
with allow_other succeeds, there will be no such message).
Furthermore, common.rc's _make_test_img should use allow-other=off for
FUSE exports, because iotests generally do not need to access images
from other users, so allow-other=on or allow-other=auto have no
advantage. OTOH, allow-other=on will not work on systems where
user_allow_other is disabled, and with allow-other=auto, we get said
error message that we would need to filter out again. Just disabling
allow-other is simplest.

We do not do any permission checks in fuse_open(), so let the kernel do
them. We already let fuse_getattr() report the proper UNIX permissions,
so this should work the way we want.
This causes a change in 308's reference output, because now opening a
non-writable export with O_RDWR fails already, instead of only actually
attempting to write to it. (That is an improvement.)

The PAPR platform describes an OS environment that's presented by
a combination of a hypervisor and firmware. The features it specifies
require collaboration between the firmware and the hypervisor.
Since the beginning, the runtime component of the firmware (RTAS) has
been implemented as a 20 byte shim which simply forwards it to
a hypercall implemented in qemu. The boot time firmware component is
SLOF - but a build that's specific to qemu, and has always needed to be
updated in sync with it. Even though we've managed to limit the amount
of runtime communication we need between qemu and SLOF, there's some,
and it has become increasingly awkward to handle as we've implemented
new features.
This implements a boot time OF client interface (CI) which is
enabled by a new "x-vof" pseries machine option (stands for "Virtual Open
Firmware). When enabled, QEMU implements the custom H_OF_CLIENT hcall
which implements Open Firmware Client Interface (OF CI). This allows
using a smaller stateless firmware which does not have to manage
the device tree.
The new "vof.bin" firmware image is included with source code under
pc-bios/. It also includes RTAS blob.
This implements a handful of CI methods just to get -kernel/-initrd
working. In particular, this implements the device tree fetching and
simple memory allocator - "claim" (an OF CI memory allocator) and updates
"/memory@0/available" to report the client about available memory.
This implements changing some device tree properties which we know how
to deal with, the rest is ignored. To allow changes, this skips
fdt_pack() when x-vof=on as not packing the blob leaves some room for
appending.
In absence of SLOF, this assigns phandles to device tree nodes to make
device tree traversing work.
When x-vof=on, this adds "/chosen" every time QEMU (re)builds a tree.
This adds basic instances support which are managed by a hash map
ihandle -> [phandle].
Before the guest started, the used memory is:
0..e60 - the initial firmware
8000..10000 - stack
400000.. - kernel
3ea0000.. - initramdisk
This OF CI does not implement "interpret".
Unlike SLOF, this does not format uninitialized nvram. Instead, this
includes a disk image with pre-formatted nvram.
With this basic support, this can only boot into kernel directly.
However this is just enough for the petitboot kernel and initradmdisk to
boot from any possible source. Note this requires reasonably recent guest
kernel with:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=df5be5be8735
The immediate benefit is much faster booting time which especially
crucial with fully emulated early CPU bring up environments. Also this
may come handy when/if GRUB-in-the-userspace sees light of the day.
This separates VOF and sPAPR in a hope that VOF bits may be reused by
other POWERPC boards which do not support pSeries.
This assumes potential support for booting from QEMU backends
such as blockdev or netdev without devices/drivers used.

backend_defaults property allow users to control if default block
properties should be decided with backend information.
If it is off, any backend information will be discarded, which is
suitable if you plan to perform live migration to a different disk backend.
If it is on, a block device may utilize backend information more
aggressively.
By default, it is auto, which uses backend information for block
sizes and ignores the others, which is consistent with the older
versions.

It can be difficult to debug issues with BHs in production environments.
Although BHs can usually be identified by looking up their ->cb()
function pointer, this requires debug information for the program. It is
also not possible to print human-readable diagnostics about BHs because
they have no identifier.
This patch adds a name to each BH. The name is not unique per instance
but differentiates between cb() functions, which is usually enough. It's
done by changing aio_bh_new() and friends to macros that stringify cb.
The next patch will use the name field when reporting leaked BHs.

Currently the SSH block driver supports MD5 and SHA1 for host key
fingerprints. This is a cryptographically sensitive operation and
so these hash algorithms are inadequate by modern standards. This
adds support for SHA256 which has been supported in libssh since
the 0.8.1 release.

When the x-blockdev-reopen was added it allowed reconfiguring the
graph by replacing backing files, but changing the 'file' option was
forbidden. Because of this restriction some operations are not
possible, notably inserting and removing block filters.
This patch adds support for replacing the 'file' option. This is
similar to replacing the backing file and the user is likewise
responsible for the correctness of the resulting graph, otherwise this
can lead to data corruption.

When creating an image file with a backing file, we generally try to
open the backing file (unless -u was specified), mostly to verify that
it is there, but also to get the file size if none was specified for the
new image.
For neither of these things do we need data I/O, and so we can pass
BDRV_O_NO_IO when opening the backing file. This allows us to open even
encrypted backing images without requiring the user to provide a secret.
This makes the -u switch in iotests 189 and 198 unnecessary (and the
$size parameter), so drop it, because this way we get regression tests
for this patch here.

If we want to wake up a coroutine from a worker thread, aio_co_wake()
currently does not work. In that scenario, aio_co_wake() calls
aio_co_enter(), but there is no current AioContext and therefore
qemu_get_current_aio_context() returns the main thread. aio_co_wake()
then attempts to call aio_context_acquire() instead of going through
aio_co_schedule().
The default case of qemu_get_current_aio_context() was added to cover
synchronous I/O started from the vCPU thread, but the main and vCPU
threads are quite different. The main thread is an I/O thread itself,
only running a more complicated event loop; the vCPU thread instead
is essentially a worker thread that occasionally calls
qemu_mutex_lock_iothread(). It is only in those critical sections
that it acts as if it were the home thread of the main AioContext.
Therefore, this patch detaches qemu_get_current_aio_context() from
iothreads, which is a useless complication. The AioContext pointer
is stored directly in the thread-local variable, including for the
main loop. Worker threads (including vCPU threads) optionally behave
as temporary home threads if they have taken the big QEMU lock,
but if that is not the case they will always schedule coroutines
on remote threads via aio_co_schedule().
With this change, the stub qemu_mutex_iothread_locked() must be changed
from true to false. The previous value of true was needed because the
main thread did not have an AioContext in the thread-local variable,
but now it does have one.

While the SB16 seems to work up to 48000 Hz, the "Sound Blaster Series
Hardware Programming Guide" limit the sampling range from 4000 Hz to
44100 Hz (Section 3-9, 3-10: Digitized Sound I/O Programming, tables
3-2 and 3-3).
Later, section 6-15 (DSP Commands) is more specific regarding the 41h /
42h registers (Set digitized sound output sampling rate):
Valid sampling rates range from 5000 to 45000 Hz inclusive.
There is no comment regarding error handling if the register is filled
with an out-of-range value. (See also section 3-28 "8-bit or 16-bit
Auto-initialize Transfer"). Assume limits are enforced in hardware.

If you configure the host compiler with a multi-command stanza like:
--cc="ccache gcc"
then the configure.sh machinery falls over with confusion. Work around
this by ensuring we correctly quote so where we need a complete
evaluation we get it. Of course the has() check needs single variable
so we need to unquote that. This does mean it essentially checks that
just the ccache command exits but if we got past that step we still
check the compiler actually does something.
