083fab0290 seabios: update to 1.11 prerelease
This is the seabios update for qemu 2.11.  Well, almost, seabios is in
freeze for the upcoming 1.11 release.  This updates seabios to current
git master snapshot, and it will be updated again to 1.11 final before
the 2.11 release.

With this two-step seabios gets some more wide testing before the actual
release and the update to 1.11 final (which will most likely happen
after qemu freeze) should have bugfix patches only.

bcf9e2c2f2 sun4u: fix assert when adding NICs which aren't the in-built model
Commit 8d93297 introduced a bug whereby non-inbuilt NICs are realized before
setting the default MAC address causing an assert. Switch NIC creation
over from pci_create_simple() to pci_create() which works exactly the
same except omitting the realize as originally intended.

6864fa3897 sun4u: update PCI topology to include simba PCI bridges
This patch updates the sun4u model to being much closer to a real Ultra 5
by moving devices behind the 2 simba PCI bridges (A and B) as found on real
hardware.

The most noticeable change introduced by this patchset is that in-built devices
are no longer attached to the PCI root bus, but instead behind PCI bridge A.
Along with this the interrupt routing is updated accordingly to match the
official documentation.

Since the existing code currently bypasses the PCI bridge interrupt
swizzling, the interrupt mapping functions are reorganised so that
pci_pbm_map_irq() is used by the PCI bridges and pci_apb_map_irq() is
used by the PCI host bridge.

Behind the sabre PCI host bridge, the PCI IO space now needs to be
split into two separate halves at 0x8000000. Therefore we also setup a new
PCI IO space region of increased size on the PCI host bridge and enable
32-bit PCI IO accesses to allow IO accesses to reach devices behind PCI
bridge B correctly.

As part of this change we also combine the onboard sunhme NIC and the ebus
into a single multi-function device as done on a real Ultra 5. For other
NICs the existing behaviour is preserved, i.e. we initialise them and
place them into the next free slot on PCI bus B.

Finally we mark the physically unavailable slots (plus slot 0 in busA) as
reserved to ensure that users can't plug devices into non-existent slots
which will break interrupt routing.

Note: since this commit changes PCI topology and interrupt routing, an
updated openbios-sparc64 binary is included with this commit containing the
associated changes to maintain bisectability.

3da023b582 scsi: reject configurations with logical block size > physical block size
Logical block size of a SCSI disk should never be larger than
physical block size. From an ATA/SCSI perspective, it makes no sense
to have the logical block size greater than the physical block size,
and it cannot even be effectively expressed in the command set. The
whole point of adding the physical block size to the ATA/SCSI command
set was to communicate a desire for a larger block size (than logical),
while maintaining backwards compatibility with legacy 512 byte block
size.

When setting logical_block_size > physical_block_size, QEMU cannot express
it in READ CAPACITY(16) output, and all it can do is set the physical
block exponent to 0 (i.e. logical_block_size == physical_block_size).
Reporting the error properly, however, is better.

f7b879e072 qdev: defer DEVICE_DEL event until instance_finalize()
DEVICE_DEL is currently emitted when a Device is unparented, as
opposed to when it is finalized. The main design motivation for this
seems to be that after unparent()/unrealize(), the Device is no
longer visible to the guest, and thus the operation is complete
from the perspective of management.

However, there are cases where remaining host-side cleanup is also
pertinent to management. The is generally handled by treating these
resources as aspects of the "backend", which can be managed via
separate interfaces/events, such as blockdev_add/del, netdev_add/del,
object_add/del, etc, but some devices do not have this level of
compartmentalization, namely vfio-pci, and possibly to lend themselves
well to it.

In the case of vfio-pci, the "backend" cleanup happens as part of
the finalization of the vfio-pci device itself, in particular the
cleanup of the VFIO group FD. Failing to wait for this cleanup can
result in tools like libvirt attempting to rebind the device to
the host while it's still being used by VFIO, which can result in
host crashes or other misbehavior depending on the host driver.

Deferring DEVICE_DEL still affords us the ability to manage backends
explicitly, while also addressing cases like vfio-pci's, so we
implement that approach here.

An alternative proposal involving having VFIO emit a separate event
to denote completion of host-side cleanup was discussed, but the
prevailing opinion seems to be that it is not worth the added
complexity, and leaves the issue open for other Device implementations
to solve in the future.

2fc06c4ac6 Revert "qdev: Free QemuOpts when the QOM path goes away"
This reverts commit abed886ec6.

This patch originally addressed an issue where a DEVICE_DELETED
event could be emitted (in device_unparent()) before a Device's
QemuOpts were cleaned up (in device_finalize()), leading to a
"duplicate ID" error if management attempted to immediately add
a device with the same ID in response to the DEVICE_DELETED event.

An alternative will be implemented in a subsequent patch where we
defer the DEVICE_DELETED event until device_finalize(), which would
also prevent the race, so we revert the original fix in preparation.

04162f8f4b qdev: store DeviceState's canonical path to use when unparenting
device_unparent(dev, ...) is called when a device is unparented,
either directly, or as a result of a parent device being
finalized, and handles some final cleanup for the device. Part
of this includes emiting a DEVICE_DELETED QMP event to notify
management, which includes the device's path in the composition
tree as provided by object_get_canonical_path().

object_get_canonical_path() assumes the device is still connected
to the machine/root container, and will assert otherwise, but
in some situations this isn't the case:

If the parent is finalized as a result of object_unparent(), it
will still be attached to the composition tree at the time any
children are unparented as a result of that same call to
object_unparent(). However, in some cases, object_unparent()
will complete without finalizing the parent device, due to
lingering references that won't be released till some time later.
One such example is if the parent has MemoryRegion children (which
take a ref on their parent), who in turn have AddressSpace's (which
take a ref on their regions), since those AddressSpaces get cleaned
up asynchronously by the RCU thread.

In this case qdev:device_unparent() may be called for a child Device
that no longer has a path to the root/machine container, causing
object_get_canonical_path() to assert.

Fix this by storing the canonical path during realize() so the
information will still be available for device_unparent() in such
cases.

libmultipath has recently changed its API.  The new API supports multi-threaded
clients better.  Unfortunately there is no backwards-compatibility, so we just
switch to the new one.  Running QEMU compiled with the new library on the old
library will likely crash, while doing the opposite will cause QEMU not to
start at all (because udev, get_multipath_config and put_multipath_config

28f77de26a vga: handle cirrus vbe mode wraparounds.
Commit "3d90c62548 vga: stop passing pointers to vga_draw_line*
functions" is incomplete.  It doesn't handle the case that the vga
rendering code tries to create a shared surface, i.e. a pixman image
backed by vga video memory.  That can not work in case the guest display
wraps from end of video memory to the start.  So force shadowing in that
case.  Also adjust the snapshot region calculation.

Can trigger with cirrus only, when programming vbe modes using the bochs
api (stdvga, also qxl and virtio-vga in vga compat mode) wrap arounds
can't happen.

f7d6bfcdc0 spapr_pci: fail gracefully with non-pseries machine types

The same thing happens with the deprecated but still available child type

db50f280cf spapr: Correct RAM size calculation for HPT resizing
In order to prevent the guest from forcing the allocation of large amounts
of qemu memory (or host kernel memory, in the case of KVM HV), we limit
the size of Hashed Page Table (HPT) it is allowed to allocated, based on
its RAM size.

However, the current calculation is not correct: it only adds up the size
of plugged memory, ignoring the base memory size.  This patch corrects it.

While we're there, use get_plugged_memory_size() instead of directly
calling pc_existing_dimms_capacity().  The only difference is that it
will abort on failure, which is right: a failure here indicates something
wrong within qemu.

4a12c699d3 ppc: pnv: use generic cpu_model parsing
use common cpu_model prasing in vl.c and set default cpu_model
using generic MachineClass::default_cpu_type.

Beside of switching to generic infrastructure it solves several
issues.

 * ppc_cpu_class_by_name() is used to deal with lower/upper case
   and alias translations into actual cpu type, which fixes
    '-M powernv -cpu power8' and '-M powernv -cpu power9_v1.0'
   usecases which error out with:
    'invalid CPU model 'FOO' for powernv machine'
 * allows to switch to lower-case typenames in pnv chip/core name
   (by convention typnames should be lower-case)
 * replace aliased names /power8, power9, .../ with exact cpu model
   names (i.e. typenames should be stable but aliases might decide to
   point to other cpu model withi family or changed by kvm). It will
   also help to simplify pnv_chip/core code and get rid of dependency
   on cpu_model parsing.

5bbb264186 ppc: spapr: register 'host' core type along with the rest of core types
consolidate 'host' core type registration by moving it from
KVM specific code into spapr_cpu_core.c, similar like it's
done in x86 target.

b51d3c8818 ppc: spapr: use cpu type name directly
replace sPAPRCPUCoreClass::cpu_class with cpu type name
since it were needed just to get that at points it were
accessed.

44cd95e31a ppc: spapr: define core types statically
spapr core type definition doesn't have any fields that
require it to be defined at runtime. So replace code
that fills in TypeInfo at runtime with static TypeInfo
array that does the same at complie time.

b8e999673b ppc: move '-cpu foo,compat=xxx' parsing into ppc_cpu_parse_featurestr()
there is a dedicated callback CPUClass::parse_features
which purpose is to convert -cpu features into a set of
global properties AND deal with compat/legacy features
that couldn't be directly translated into CPU's properties.

Create ppc variant of it (ppc_cpu_parse_featurestr) and
move 'compat=val' handling from spapr_cpu_core.c into it.
That removes a dependency of board/core code on cpu_model
parsing and would let to reuse common -cpu parsing
introduced by 6063d4c0

Set "max-cpu-compat" property only if it exists, in practice
it should limit 'compat' hack to spapr machine and allow
to avoid including machine/spapr headers in target/ppc/cpu.c
