ac41881b48 pc: avoid duplicate names for ROM MRs
Since
commit 04920fc0fa
    loader: store FW CFG ROM files in RAM
RAM MRs including ROM files in FW CFGs are created
and named using the file basename.

This becomes problematic if these names are
supplied by user, since the basename might not
be unique.

There are two cases we care about:
- option-rom flag.
- option ROM for devices. This triggers e.g. when
  using rombar=0.

At the moment we get an assert. E.g
qemu -option-rom /usr/share/ipxe/8086100e.rom -option-rom
/usr/share/ipxe.efi/8086100e.rom
RAMBlock "/rom@genroms/8086100e.rom" already registered, abort!

This is a regression from 1.6.

For now let's keep it simple and just avoid creating the
MRs in case of option ROMs.

when using 1.7 machine types, enable
option ROMs in RAM to match that version.

98bc3ab0f2 loader: rename in_ram/has_mr
we put copy of ROMs in MR for migration.
but the name rom_in_ram makes one think we
load it in guest RAM.
Rename has_mr to make intent clearer.

61de36761b qdev: Keep global allocation counter per bus
When we have 2 separate qdev devices that both create a qbus of the
same type without specifying a bus name or device name, we end up
with two buses of the same name, such as ide.0 on the Mac machines:

  dev: macio-ide, id ""
    bus: ide.0
      type IDE
  dev: macio-ide, id ""
    bus: ide.0
      type IDE

If we now spawn a device that connects to a ide.0 the last created
bus gets the device, with the first created bus inaccessible to the
command line.

After some discussion on IRC we concluded that the best quick fix way
forward for this is to make automated bus-class type based allocation
count a global counter. That's what this patch implements. With this
we instead get

  dev: macio-ide, id ""
    bus: ide.1
      type IDE
  dev: macio-ide, id ""
    bus: ide.0
      type IDE

on the example mentioned above.

This also means that if you did -device ...,bus=ide.0 you got a device
on the first bus (the last created one) before this patch and get that
device on the second one (the first created one) now.  Breaks
migration unless you change bus=ide.0 to bus=ide.1 on the destination.

This is intended and makes the bus enumeration work as expected.

As per review request follows a list of otherwise affected boards and
the reasoning for the conclusion that they are ok:

   target      machine         bus id              times
   ------      -------         ------              -----

   aarch64     n800            i2c-bus.0           2
   aarch64     n810            i2c-bus.0           2
   arm         n800            i2c-bus.0           2
   arm         n810            i2c-bus.0           2

-> Devices are only created explicitly on one of the two buses, using
   s->mpu->i2c[0], so no change to the guest.

   aarch64     vexpress-a15    virtio-mmio-bus.0   4
   aarch64     vexpress-a9     virtio-mmio-bus.0   4
   aarch64     virt            virtio-mmio-bus.0   32
   arm         vexpress-a15    virtio-mmio-bus.0   4
   arm         vexpress-a9     virtio-mmio-bus.0   4
   arm         virt            virtio-mmio-bus.0   32

-> Makes -device bus= work for all virtio-mmio buses.  Breaks
   migration.  Workaround for migration from old to new: specify
   virtio-mmio-bus.4 or .32 respectively rather than .0 on the
   destination.

   mips64el    fulong2e        usb-bus.0           2

-> Normal USB operation not affected. Migration driver needs command
   line to use the other bus.

18674b2678 elf-loader: add more return codes
The existing load_elf() just returns -1 if it fails to load ELF. However
it could be smarter than this and tell more about the failure such as
wrong endianness or incompatible platform.

This adds additional return codes for wrong architecture, wrong
endianness and if the image is not ELF at all.

This adds a load_elf_strerror() helper to convert return codes into
string messages.

This fixes handling of what load_elf() returns for s390x, other
callers just check the return value for <0 and this remains unchanged.

9c06a1f79f KVM: Split QEMUMachine typedef into separate header
Older gcc versions (such as the one in SLES11) get confused when you declare
a typedef on the same struct twice.

To work around that limitation, let's extract the QEMUMachine typedef into a
separate header file that is guarded by preprocessor duplicate include checks.

This fixes the following type of compile errors for me:

  In file included from vl.c:125:
  include/hw/xen/xen.h:39: error: redefinition of typedef "QEMUMachine"
  include/sysemu/kvm.h:155: error: previous declaration of "QEMUMachine" was here

1da41cc1c6 arm: vgic device control api support
Support creating the ARM vgic device through the device control API and
setting the base address for the distributor and cpu interfaces in KVM
VMs using this API.

Because the older KVM_CREATE_IRQCHIP interface needs the irq chip to be
created prior to creating the VCPUs, we first test if we can use the
device control API in kvm_arch_irqchip_create (using the test flag from
the device control API).  If we cannot, it means we have to fall back to
KVM_CREATE_IRQCHIP and use the older ioctl at this point in time.  If
however, we can use the device control API, we don't do anything and
wait until the arm_gic_kvm driver initializes and let that use the
device control API.

c5f52875b9 scsi: Change scsi sense buf size to 252
Current buffer size fails the assersion check in like

    hw/scsi/scsi-bus.c:1655:    assert(req->sense_len <= sizeof(req->sense));

when backend (block/iscsi.c) returns more data then 96.

Exercise the core dump path by booting an Gentoo ISO with scsi-generic
device backed with iscsi (built with libiscsi 1.7.0):

    x86_64-softmmu/qemu-system-x86_64 \

    qemu-system-x86_64: hw/scsi/scsi-bus.c:1655: scsi_req_complete:
    Assertion `req->sense_len <= sizeof(req->sense)' failed.

According to SPC-4, section 4.5.2.1, 252 is the limit of sense data. So
increase the value to fix it.

Also remove duplicated define for the macro.

1a37eca107 qdev: add "hotpluggable" property to Device
Currently it's possible to make PCIDevice not hotpluggable
by using no_hotplug field of PCIDeviceClass. However it
limits this only to PCI devices and prevents from
generalizing hotplug code.

So add similar field to DeviceClass so it could be reused
with other Devices and would allow to replace PCI specific
hotplug callbacks with generic implementation. Following
patches will replace PCIDeviceClass.no_hotplug with this
new property.

In addition expose field as "hotpluggable" readonly property,
to make it possible to read its value via QOM interface.

Make DeviceClass hotpluggable by default as it was assumed
before.

will allow to avoid adding equivalent field to
DimmBus with possiblitity to refactor other BUSes
to use it instead of custom field.
In addition once all users of allow_hotplug field
are converted to new API, link could replace

Right now the arm gic emulation doesn't keep track of the source of an
SGI (which apparently Linux guests don't use, or they're fine with
assuming CPU 0 always).

Add the necessary matrix on the GICState structure and maintain the data
when setting and clearing the pending state of an IRQ and make the state
visible to the guest.

Note that we always choose to present the source as the lowest-numbered
CPU in case multiple cores have signalled the same SGI number to a core
on the system.

99d09dd328 pcihp: make pci_read() mmio calback compatible with legacy ACPI hotplug
due to recent change introduced by:
"pcihp: reduce number of device check events"

'up' field is cleared right after it's read.
This is incompatible with legacy BIOS ACPI code
where PCNF ACPI method reads this field 32 times.

To make pci_read mmio callback compatible with legacy
'up' behavior, pcihp code will need to know in which
mode it runs add 'legacy_piix' field to AcpiPciHpState
structure and alter register behavior accordingly.

5a2223ca26 pcihp: reduce number of device check events
PIIX created a made-up value for the UP register since it was read by
guest 32 times for each interrupt.
There's no reason to do this for the new PCIHP: register is only read
once for each interrupt, so clean up code by making read act as an
interrupt acknowledgement: the new UP register clear on read.

In this way we cut down the number of bus rescans
by a factor of 32, and drop a bunch of code that's
now unused.

20bcf73fa8 vmstate: Make VMSTATE_STRUCT_POINTER take type, not ptr-to-type
The VMSTATE_STRUCT_POINTER macros are a bit odd in that they
must be passed an argument "FooType *" rather than just taking
the FooType. They're only used in one place, so it's easy to
tidy this up. This also lets us use the macro to replace the
hand-rolled VMSTATE_PTIMER.

db4728e6fe pcihp: generalization of piix4 acpi
Add ACPI based PCI hotplug library with bridge hotplug
support.
Design
   - each bus gets assigned "bsel" property.
   - ACPI code writes this number
     to a new BNUM register, then uses existing
     UP/DOWN registers to probe slot status;
     to eject, write number to BNUM register,
     then slot into existing EJ.

The interface is actually backwards-compatible with
existing PIIX4 ACPI (though not migration compatible).

This is split out from PIIX4 codebase so we can
reuse it for Q35 as well.

6780a22cc7 qdev: Drop misleading qbus_free() function
Same reasoning as commit 02a5c4c974
("qdev: Drop misleading qdev_free() function").  The qbus_free()
function removes the child from the namespace and decrements the
reference count.  It does not, however, guarantee to free the child
since the refcount may still be held.

Just call object_unparent() directly.

ddaaefb4dd piix: fix 32bit pci hole
Make the 32bit pci hole start at end of ram, so all possible address
space is covered.

We used to try and make addresses aligned so they are easier to cover
with MTRRs, but since they are cosmetic on KVM, this is probably not
worth worrying about.
Of course the firmware can use less than that.  Leaving space unused is
no problem, mapping pci bars outside the hole causes problems though.

dcc209314a qdev: switch reset to post-order
Post-order is the only sensible direction for the reset signals.
For example, suppose pre-order is used and the parent has some data
structures that cache children state (for example a list of active
requests).  When the reset method is invoked on the parent, these caches
could be in any state.

If post-order is used, on the other hand, these will be in a known state
when the reset method is invoked on the parent.

This change means that it is no longer possible to block the visit of
the devices, so the callback is changed to return void.  This is not
a problem, because PCI was returning 1 exactly in order to achieve the
same ordering that this patch implements.

PCI can then rely on the qdev core having sent a "reset signal" (whatever
that means) to the device, and only do the PCI-specific initialization
with pci_do_device_reset.

Resetting should be done in post-order, not pre-order.  However,
qdev_walk_children and qbus_walk_children do not allow this.  Fix
it by adding two extra arguments to the functions.

efec3dd631 qdev: Replace no_user by cannot_instantiate_with_device_add_yet
In an ideal world, machines can be built by wiring devices together
with configuration, not code.  Unfortunately, that's not the world we
live in right now.  We still have quite a few devices that need to be
wired up by code.  If you try to device_add such a device, it'll fail
in sometimes mysterious ways.  If you're lucky, you get an
unmysterious immediate crash.

To protect users from such badness, DeviceClass member no_user used to
make device models unavailable with -device / device_add, but that
regressed in commit 18b6dad.  The device model is still omitted from
help, but is available anyway.

Attempts to fix the regression have been rejected with the argument
that the purpose of no_user isn't clear, and it's prone to misuse.

This commit clarifies no_user's purpose.  Anthony suggested to rename
it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which
I shorten somewhat to keep checkpatch happy.  While there, make it
bool.

Every use of cannot_instantiate_with_device_add_yet gets a FIXME
comment asking for rationale.  The next few commits will clean them
all up, either by providing a rationale, or by getting rid of the use.

With that done, the regression fix is hopefully acceptable.

ibm,set-system-parameter RTAS calls.

The only parameter handled at the moment is
"platform-processor-diagnostics-run-mode" which is always disabled and
does not support changing. This is expected to make
"ppc64_cpu --run-mode=1" happy.
