Peter Maydell d341d9f306 fpu: Replace uint8 typedef with uint8_t
Replace the uint8 softfloat-specific typedef with uint8_t.
This change was made with

find include hw fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\buint8\b/uint8_t/g'

together with manual removal of the typedef definition and
manual fixing of more erroneous uses found via test compilation.

It turns out that the only code using this type is an accidental
use where uint8_t was intended anyway...

Peter Maydell 3a87d00910 fpu: Replace uint32 typedef with uint32_t
Replace the uint32 softfloat-specific typedef with uint32_t.
This change was made with

find include hw fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\buint32\b/uint32_t/g'

together with manual removal of the typedef definition,
manual undoing of various mis-hits, and another couple of
fixes found via test compilation.

All the uses in hw/ were using the wrong type by mistake.

Haozhong Zhang 36f96c4b6b target-i386: Add support to migrate vcpu's TSC rate
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.

qbus_realize() adds busses as a QOM child of the device in addition to
adding it to the qdev bus list. Change get_child_bus() to use the QOM
child if it is available. This takes priority over the bus-list, but
the child object is checked for type correctness.

This prepares support for aliasing of buses. The use case is SoCs,
where a SoC container needs to present buses to the board level, but
the buses are implemented by controller IP we already model as self
contained qbus-containing devices.

Alex Williamson 95239e1625 vfio/pci: Lazy PBA emulation
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.

Alex Williamson f5793fd9e1 vfio/pci-quirks: Only quirk to size of PCI config space
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.

Paolo Bonzini abed886ec6 qdev: Free QemuOpts when the QOM path goes away
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
been sent to plug this other bug.  Character devices also have yet to
be fixed.

Daniel P. Berrange 7746abd8e9 qom: Change object property iterator API contract
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))) {
     ...
  }

Daniel P. Berrange 46f296cd3a qemu-char: delete send_all/recv_all helper methods
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.

P J P 4c1396cb57 i386: avoid null pointer dereference
Hello,

A null pointer dereference issue was reported by Mr Ling Liu, CC'd here. It
occurs while doing I/O port write operations via hmp interface. In that,
'current_cpu' remains null as it is not called from cpu_exec loop, which
results in the said issue.

Below is a proposed (tested)patch to fix this issue; Does it look okay?

Subject: [PATCH] i386: avoid null pointer dereference

When I/O port write operation is called from hmp interface,
'current_cpu' remains null, as it is not called from cpu_exec()
loop. This leads to a null pointer dereference in vapic_write
routine. Add check to avoid it.

Paolo Bonzini 3daa41078a scsi: revert change to scsi_req_cancel_async and add assertions
Fam Zheng noticed that the change in commit 36896bf ("scsi: always call
notifier on async cancellation", 2015-12-16) could cause a leak of
the request; scsi_req_cancel_async now calls scsi_req_ref
multiple times for multiple cancellations, but there is only
one call to scsi_req_cancel_complete.

So revert the patch and instead assert that the problematic case (a call
to scsi_req_cancel_async after the aiocb has been completed) cannot
happen.

Alistair Francis dc3b89ef87 xlnx-zynqmp: Add support for high DDR memory regions
The Xilinx ZynqMP SoC and EP108 board supports three memory regions:
 - A 2GB region starting at 0
 - A 32GB region starting at 32GB
 - A 256GB region starting at 768GB

This patch adds support for the first two memory regions, which is
automatically created based on the size specified by the QEMU memory
command line argument.

On hardware the physical memory region is one continuous region, it is then
mapped into the three different regions by the DDRC. As we don't model the
DDRC this is done at startup by QEMU. The board creates the memory region and
then passes that memory region to the SoC. The SoC then maps the memory
regions.

The arguments of error_report() should yield a short error string
without newlines.

A few places try to print additional help after the error message by
embedding newlines in the error string.  That's nice, but let's do it
the right way.  Commit 474c213 cleaned up some, but they keep coming
back.  Offenders tracked down with the Coccinelle semantic patch from
commit 312fd5f.
