The 2.88 drive is more suitable as a default because
it can still read 1.44 images correctly, but the reverse
is not true.
Since there exist virtio-win drivers that are shipped on
2.88 floppy images, this patch will allow VMs booted without
a floppy disk inserted to later insert a 2.88MB floppy and
have that work.
This patch has been tested with msdos, freedos, fedora,
windows 8 and windows 10 without issue: if problems do
arise for certain guests being unable to cope with 2.88MB
drives as the default, they are in the minority and can use
type=144 as needed (or insert a proper boot medium and omit
type=144/288 or use type=auto) to obtain different drive types.
As icing, the default will remain auto/144 for any pre-2.6
machine types, hopefully minimizing the impact of this change
in legacy hw to basically zero.

This one is the crazy one.
fd_revalidate currently uses pick_geometry to tell if the diskette
geometry has changed upon an eject/insert event, but it won't allow us
to insert a 1.44MB diskette into a 2.88MB drive. This is inflexible.
The new algorithm applies a new heuristic to guessing disk geometries
that allows us to switch diskette types as long as the physical size
matches before falling back to the old heuristic.
The old one is roughly:
- If the size (sectors) and type matches, choose it.
- Fall back to the first geometry that matched our type.
The new one is:
- If the size (sectors) and type matches, choose it.
- If the size (sectors) and physical size match, choose it.
- Fall back to the first geometry that matched our type.

2.88MB capable drives can accept 1.44MB floppies,
for instance. To rework the pick_geometry function,
we need to know if our current drive can even accept
the type of disks we're considering.
NB: This allows us to distinguish between all of the
"total sectors" collisions between 1.20MB and 1.44MB
diskette types, by using the physical drive size as a
differentiator.

This patch adds a new explicit Floppy Drive Type option. The existing
behavior in QEMU is to automatically guess a drive type based on the
media inserted, or if a diskette is not present, arbitrarily assign one.
This behavior can be described as "auto." This patch adds the option
to pick an explicit behavior: 120, 144, 288 or none. The new "auto"
option is intended to mimic current behavior, while the other types
pick one explicitly.
Set the type given by the CLI during fd_init. If the type remains the
default (auto), we'll attempt to scan an inserted diskette if present
to determine a type. If auto is selected but no diskette is present,
we fall back to a predetermined default (currently 1.44MB to match
legacy QEMU behavior.)

Currently, QEMU chooses a drive type automatically based on the inserted
media. If there is no disk inserted, it chooses a 1.44MB drive type.
Change this behavior to be configurable, but leave it defaulted to 1.44.
This is not earnestly intended to be used by a user or a management
library, but rather exists so that pre-2.6 board types can configure it
to be a legacy value.

Split apart pick_geometry by creating a pick_drive routine that will only
ever called during device bring-up instead of relying on pick_geometry to
be used in both cases.
With this change, the drive field is changed to be 'write once'. It is
not altered after the initialization routines exit.
media_validated does not need to be migrated. The target VM
will just revalidate the media on post_load anyway.

pick_geometry is a convoluted function that makes it difficult to tell
at a glance what QEMU's current behavior for choosing a floppy drive
type is when it can't quite identify the diskette.
The code iterates over all entries in the candidate geometry table
("fd_formats") and if our specific drive type matches a row in the table,
then either "match" is set to that entry (an exact match) and the loop
exits, or "first_match" will be non-negative (the first such entry that
shares the same drive type), and the loop continues. If our specific
drive type is NONE, then all drive types in the candidate geometry table
are considered. After iteration, if "match" was not set, we fall back to
"first match".
This means that either "match" was set, or we exited the loop without an
exact match, in which case:
- If drive type is NONE, the default is truly fd_formats[0], a 1.44MB
type, because "first_match" will always get set to the first item.
- If drive type is not NONE, pick_geometry's iteration was fussier and
only looked at rows that matched our drive type. However, since all
possible drive types are represented in the table, we still know that
"first match" was set.
- If drive type is not NONE and the fd_formats table lists no options for
our drive type, we choose fd_formats[1], an incomprehensibly bizarre
choice that can never happen anyway.
Correct this: If first_match is -1, it can ONLY mean we didn't edit our
fd_formats table correctly. Throw an assertion instead.

Currently, 'drive' is used both to represent the current diskette
type as well as the current drive type.
This patch adds a 'disk' field that is updated explicitly to match
the type of the disk.
As of this patch, disk and drive are always the same, but forthcoming
patches to change the behavior of pick_geometry will invalidate this
assumption.
disk does not need to be migrated because it is not user-visible state
nor is it currently used for any calculations. It is purely informative,
and will be rebuilt automatically via fd_revalidate on the new host.

In b7eb0c9:
hw/block-common: Factor out fall back to legacy -drive cyls=...
'blkconf_geometry()' was introduced, factoring out CHS limit validation
code that was repeated in ide, scsi, virtio-blk.
The original IDE CHS limit prior b7eb0c9 was 65535,16,255 (as per ATA
CHS addressing).
However the 'cyls_max' argument passed to 'blkconf_geometry' in the
ide_dev_initfn case was accidentally set to 65536 instead of 65535.
Fix, providing the correct 'cyls_max'.

This patch enables migrating vcpu's TSC rate. If KVM on the
destination machine supports TSC scaling, guest programs will
observe a consistent TSC rate across the migration.
If TSC scaling is not supported on the destination machine, the
migration will not be aborted and QEMU on the destination will
not set vcpu's TSC rate to the migrated value.
If vcpu's TSC rate specified by CPU option 'tsc-freq' on the
destination machine is inconsistent with the migrated TSC rate,
the migration will be aborted.
For backwards compatibility, the migration of vcpu's TSC rate is
disabled on pc-*-2.5 and older machine types.

The PCI spec recommends devices use additional alignment for MSI-X
data structures to allow software to map them to separate processor
pages. One advantage of doing this is that we can emulate those data
structures without a significant performance impact to the operation
of the device. Some devices fail to implement that suggestion and
assigned device performance suffers.
One such case of this is a Mellanox MT27500 series, ConnectX-3 VF,
where the MSI-X vector table and PBA are aligned on separate 4K
pages. If PBA emulation is enabled, performance suffers. It's not
clear how much value we get from PBA emulation, but the solution here
is to only lazily enable the emulated PBA when a masked MSI-X vector
fires. We then attempt to more aggresively disable the PBA memory
region any time a vector is unmasked. The expectation is then that
a typical VM will run entirely with PBA emulation disabled, and only
when used is that emulation re-enabled.

For quirks that support the full PCIe extended config space, limit the
quirk to only the size of config space available through vfio. This
allows host systems with broken MMCONFIG regions to still make use of
these quirks without generating bad address faults trying to access
beyond the end of config space exposed through vfio. This may expose
direct access to the mirror of extended config space, only trapping
the sub-range of standard config space, but allowing this makes the
quirk, and thus the device, functional. We expect that only device
specific accesses make use of the mirror, not general extended PCI
capability accesses, so any virtualization in this space is likely
unnecessary anyway, and the device is still IOMMU isolated, so it
should only be able to hurt itself through any bogus configurations
enabled by this space.

Otherwise there is a race where the DEVICE_DELETED event has been sent but
attempts to reuse the ID will fail.
Note that similar races exist for other QemuOpts, which this patch
does not attempt to fix.
For example, if the device is a block device, then unplugging it also
deletes its backend. However, this backend's get deleted in
drive_info_del(), which is only called when properties are
destroyed. Just like device_finalize(), drive_info_del() is called
some time after DEVICE_DELETED is sent. A separate patch series has

Currently the ObjectProperty iterator API works as follows:
ObjectPropertyIterator *iter;
iter = object_property_iter_init(obj);
while ((prop = object_property_iter_next(iter))) {
...
}
object_property_iter_free(iter);
This has the benefit that the ObjectPropertyIterator struct
can be opaque, but has the downside that callers need to
explicitly call a free function. It is also not in keeping
with iterator style used elsewhere in QEMU/GLib2.
This patch changes the API to use stack allocation instead:
ObjectPropertyIterator iter;
object_property_iter_init(&iter, obj);
while ((prop = object_property_iter_next(&iter))) {
...
}

Convert the SPARC CPU from cpu_load/save functions to VMStateDescription.
We preserve migration compatibility with the previous version
(required for SPARC32 but not necessarily for SPARC64).

[PMM:
* Rebase and update to apply to master
* VMSTATE_STRUCT_POINTER now takes type, not pointer-to-type
* QEMUTimer* are migrated via VMSTATE_TIMER_PTR
* Put CPUTimer vmstate struct inside TARGET_SPARC64 ifdef
* Convert handling of PSR to use a vmstate_psr, like Alpha and ARM

The qemu-char.c contains two helper methods send_all
and recv_all. These are in fact declared in sockets.h
so ought to have been in util/qemu-sockets.c. For added
fun the impl of recv_all is completely missing on Win32.
Fortunately there is only a single caller of these
methods, the TPM passthrough code, which is only
ever compiled on Linux. With only a single caller
these helpers are not compelling enough to keep so
inline them in the TPM code, avoiding the need to
fix the missing recv_all on Win32.
