Where Neon instructions are floating point operations, we
mostly use the old VFP utility functions like gen_vfp_abs()
which work on the TCG globals cpu_F0s and cpu_F1s. The
Neon for-each-element loop conditionally loads the inputs
into either a plain old TCG temporary for most operations
or into cpu_F0s for float operations, and similarly stores
back either cpu_F0s or the temporary.
Switch NEON_2RM_VABS_F away from using cpu_F0s, and
update neon_2rm_is_float_op() accordingly.

The SSE-200 hardware has configurable integration settings which
determine whether its two CPUs have the FPU and DSP:
* CPU0_FPU (default 0)
* CPU0_DSP (default 0)
* CPU1_FPU (default 1)
* CPU1_DSP (default 1)
Similarly, the IoTKit has settings for its single CPU:
* CPU0_FPU (default 1)
* CPU0_DSP (default 1)
Of our four boards that use either the IoTKit or the SSE-200:
* mps2-an505, mps2-an521 and musca-a use the default settings
* musca-b1 enables FPU and DSP on both CPUs
Currently QEMU models all these boards using CPUs with
both FPU and DSP enabled. This means that we are incorrect
for mps2-an521 and musca-a, which should not have FPU or DSP
on CPU0.
Create QOM properties on the ARMSSE devices corresponding to the
default h/w integration settings, and make the Musca-B1 board
enable FPU and DSP on both CPUs. This fixes the mps2-an521
and musca-a behaviour, and leaves the musca-b1 and mps2-an505
behaviour unchanged.

Since Linux v3.17, the kernel's Image header includes a field image_size,
which gives the total size of the kernel including unpopulated data
sections such as the BSS). If this is present, then return it from
load_aarch64_image() as the true size of the kernel rather than
just using the size of the Image file itself. This allows the code
which calculates where to put the initrd to avoid putting it in
the kernel's BSS area.
This means that we should be able to reliably load kernel images
which are larger than 128MB without accidentally putting the
initrd or dtb in locations that clash with the kernel itself.

We currently put the initrd at the smaller of:
* 128MB into RAM
* halfway into the RAM
(with the dtb following it).
However for large kernels this might mean that the kernel
overlaps the initrd. For some kinds of kernel (self-decompressing
32-bit kernels, and ELF images with a BSS section at the end)
we don't know the exact size, but even there we have a
minimum size. Put the initrd at least further into RAM than
that. For image formats that can give us an exact kernel size, this
will mean that we definitely avoid overlaying kernel and initrd.

incorrect assumption that info->ram_size can be treated as the
address of the end of RAM, as for instance when we calculate the

This is wrong, because many Arm boards (including "virt") specify

starts at a non-zero physical address.

Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
This patch changes the handling of the mmconfig area. Thanks to the
pci(e) expander devices we already have the logic to exclude address
ranges from PCI0._CRS. We can simply add the mmconfig address range
to the list get it excluded as well.
With that in place we can go with a fixed pci hole which covers the
whole area from the end of (low) ram to the ioapic.
This will make the whole logic alot less fragile. No matter where the
firmware places the mmconfig xbar, things should work correctly. The
guest also gets a bit more PCI address space (seabios boot):
# cat /proc/iomem
[ ... ]
7ffdd000-7fffffff : reserved
80000000-afffffff : PCI Bus 0000:00 <<-- this is new
b0000000-bfffffff : PCI MMCONFIG 0000 [bus 00-ff]
b0000000-bfffffff : reserved
c0000000-febfffff : PCI Bus 0000:00
f8000000-fbffffff : 0000:00:01.0
[ ... ]

Edk2 commit f53de8aecb12 ("edk2: Add License-History.txt", 2019-04-09)
added a new file called "License-History.txt", describing license and
contributor agreement changes over time.
(2) For advacing edk2's OpenSSL git submodule to the 1.1.1b release, a
more up-to-date ArmSoftFloatLib instance became necessary, on 32-bit
ARM. Therefore, the embedded (and by now, obsolete) Berkeley SoftFloat
library was replaced with a git submodule of the same, checked out at
the latest release ("3e", plus a typo fix on top -- commit
b64af41c3276). This was implemented for TianoCore Bugzilla
https://bugzilla.tianocore.org/show_bug.cgi?id=1845
in edk2 commit range b6cfa686e42d..371e7001e8d5.

At tag "edk2-stable201905", the build flags HTTP_BOOT_ENABLE and
TLS_ENABLE have become useless. Their roles have been taken by
NETWORK_HTTP_BOOT_ENABLE and NETWORK_TLS_ENABLE, respectively. Remove the
old build flags.

Due to edk2 commits 631195044ff0 ("OvmfPkg: Update DSC/FDF to use
NetworkPkg's include fragment file.", 2019-05-16) and 157a3b1aa50f
("ArmVirtPkg: Update DSC/FDF to use NetworkPkg's include fragment file.",
2019-05-16), we'll have to pefix the HTTP_BOOT_ENABLE and TLS_ENABLE build
flags with "NETWORK_", for building edk2 at tag "edk2-stable201905".
Right now the new flags are no-ops, so we can insert them separately,
before advancing our edk2 submodule reference. We will remove the old
flags afterwards.

Together with @iotypes and @sector, this can be used to trap e.g. the
first read or write access to a certain sector without having to know
what happens internally in the block layer, i.e. which "real" events
happen right before such an access.

This new error option allows users of blkdebug to inject errors only on
certain kinds of I/O operations. Users usually want to make a very
specific operation fail, not just any; but right now they simply hope
that the event that triggers the error injection is followed up with
that very operation. That may not be true, however, because the block
layer is changing (including blkdebug, which may increase the number of
types of I/O operations on which to inject errors).
The new option's default has been chosen to keep backwards
compatibility.
Note that similar to the internal representation, we could choose to
expose this option as a list of I/O types. But there is no practical
use for this, because as described above, users usually know exactly
which kind of operation they want to make fail, so there is no need to
specify multiple I/O types at once. In addition, exposing this option
as a list would require non-trivial changes to qemu_opts_absorb_qdict().

This adds a salvaging mode (--salvage) to qemu-img convert which ignores
read errors and treats the respective areas as containing only zeroes.
This can be used for instance to at least partially recover the data
from terminally corrupted qcow2 images.

Move img_convert()'s quiet flag into the ImgConvertState so it is
accessible by nested functions. -q dictates that it suppresses anything
but errors, so if those functions want to emit warnings, they need to
query this flag first. (There currently are no such warnings, but there
will be as of the next patch.)

A snapshot is something that reflects the state of something at a
certain point in time. It does not change.
The file our snapshot commands create (or the node they install) is not
a snapshot, as it does change over time. It is an overlay. We cannot
do anything about the parameter names, but we can at least adjust the
descriptions to reflect that fact.

Test fails at least for qcow, because of different cluster sizes in
base and top (and therefore different granularities of bitmaps we are
trying to merge).
The test aim is to check block-dirty-bitmap-merge between different
nodes functionality, no needs to check all formats. So, let's just drop
support for anything except qcow2.

The uninitialized memory allocated for the command FIFO of the
floppy controller during the VM hardware initialization incurs
many unwanted reports by Valgrind when VM state is being saved.
That verbosity hardens a search for the real memory issues when
the iotests run. Particularly, the patch eliminates 20 unnecessary
reports of the Valgrind tool in the iotest #169.

In 219, we wait for the job to make progress before we emit its status.
This makes the output reliable. We do not wait for any more progress if
the job's current-progress already matches its total-progress.
Unfortunately, there is a bug: Right after the job has been started,
it's possible that total-progress is still 0. In that case, we may skip
the first progress-making step and keep ending up 64 kB short.
To fix that bug, we can simply wait for total-progress to reach 4 MB
(the image size) after starting the job.

It is possible for an empty file to take up blocks on a filesystem, for
example:
$ qemu-img create -f raw test.img 1G
Formatting 'test.img', fmt=raw size=1073741824
$ mkfs.ext4 -I 128 -q test.img
$ mkdir test-mount
$ sudo mount -o loop test.img test-mount
$ sudo touch test-mount/test-file
$ stat -c 'blocks=%b' test-mount/test-file
blocks=8
These extra blocks (one cluster) are apparently used for metadata,
because they are always there, on top of blocks used for data:
$ sudo dd if=/dev/zero of=test-mount/test-file bs=1M count=1
1+0 records in
1+0 records out
1048576 bytes (1.0 MB, 1.0 MiB) copied, 0.00135339 s, 775 MB/s
$ stat -c 'blocks=%b' test-mount/test-file
blocks=2056
Make iotest 175 take this into account.
