6652d0811c virtio-pci: don't try to mask or unmask vqs without notifiers
We should validate the vq index against nvqs_with_notifiers. Otherwise we may
try to mask or unmask vector for vqs without notifiers (e.g control vq). This
will lead qemu abort on kvm_irqchip_commit_routes() when trying to boot win8.1
guest.

Fixes 851c2a75a6 ("virtio-pci: speedup MSI-X
masking and unmasking")

557772f26b hw/q35: fix floppy controller definition in ich9
In DSDT FDC0 declares the IO region as IO(Decode16, 0x03F2, 0x03F2, 0x00, 0x04).
Use the same in lpc_ich9 initialization code.
Now the floppy drive is detected correctly on Windows.

Based on patch by Nikolay Nikolaev:
Vhost-user will implement the multi queue support in a similar way
to what vhost already has - a separate thread for each queue.
To enable the multi queue functionality - a new command line parameter
"queues" is introduced for the vhost-user netdev.

019a3edbb2 virtio: make features 64bit wide
Make features 64bit wide everywhere.

On migration a full 64bit guest_features field is sent if one of the
high bits is set, in addition to the lower 32bit guest_features field
which must stay for compatibility reasons.  That way we send the lower
32 feature bits twice, but the code is simpler because we don't have
to split and compose the 64bit features into two 32bit fields.

116694c34a Extend TPM TIS interface to support TPM 2
Following the recent upgrade to version 1.3, extend the TPM TIS
interface with capabilities introduced for support of a TPM 2.

TPM TIS for TPM 2 introduced the following extensions beyond the
TPM TIS 1.3 (used for TPM 1.2):

- A new 32bit interface Id register was introduced.
- New flags for the status (STS) register were defined.
- New flags for the capability flags were defined.

Support the above if a TPM TIS 1.3 for TPM 2 is used with a TPM 2
on the backend side. Support the old TPM TIS 1.3 configuration if a
TPM 1.2 is being used. A subsequent patch will then determine which
TPM version is being used in the backend.

- "-device isa-fdc" is not passed on the command line (nor in the config

- no "-drive if=floppy,..." is requested.

6cd2234ccb i386/pc_q35: don't insist on board FDC if there's no default floppy
The "no_floppy = 1" machine class setting causes "default_floppy" in
main() to become zero. Consequently, default_drive() will not call
drive_add() and drive_new() for IF_FLOPPY, index=0, meaning that no
default floppy drive will be created for the virtual machine. In that
case, board code should also not insist on the creation of the
board-default FDC.

The board-default FDC will still be created if the user requests a floppy
drive with "-drive if=floppy".

Additionally, separate FDCs can be specified manually with "-device
isa-fdc". They allow the

  -device isa-fdc,driveA=...

syntax that is more flexible than the one required by the board-default
FDC:

  -global isa-fdc.driveA=...

This patch doesn't change the behavior observably, as all Q35 machine
types have "no_floppy = 0".

Even if board code decides not to request the creation of the FDC (keyed

nevertheless if the user passes '-drive if=floppy' on the command line.

Otherwise '-drive if=floppy' would break without explicit '-device

fd53c87cf6 i386/pc: pc_basic_device_init(): delegate FDC creation request
This patch introduces no observable change, but it allows the callers of
pc_basic_device_init(), ie. pc_init1() and pc_q35_init(), to request (or
not request) the creation of the FDC explicitly.

At the moment both callers pass constant create_fdctrl=true (hence no
observable change).

Assuming a board passes create_fdctrl=false, "floppy" will be NULL on
output, and (beyond the FDC not being created) that NULL will be passed on
to pc_cmos_init(). Luckily, pc_cmos_init() already handles that case.

This patch passes error pointer to transport specific device_plugged()
callback. Through this way, device_plugged() can do some transport
specific check and fail. This will be uesd by following patches that
check the number of virtqueues against the transport limitation.

cf34f533a1 virtio: move VIRTIO_F_NOTIFY_ON_EMPTY into core
Nearly all transports have been offering VIRTIO_F_NOTIFY_ON_EMPTY,
s390-virtio being the exception. There's no reason why it shouldn't
offer it as well, though (handling is done in core anyway), so let's
move it to the common virtio features.

While we're changing it anyway, fix the indentation for the
DEFINE_VIRTIO_COMMON_FEATURES macro.

6b8f102054 virtio: move host_features
Move host_features from the individual transport proxies into
the virtio device. Transports may continue to add feature bits
during device plugging.

This should it make easier to offer different sets of host features
for virtio-1/transitional support.

2332333c97 pc: acpi: fix pvpanic for buggy guests
In the old times, we always had pvpanic in ACPI and a _STA method told
the guest not to use it.  Automatic generation dropped the _STA method
as the specification says that missing _STA means enabled and working.
Some guests (Linux) had buggy drivers and this change made them unable
to utilize pvpanic.

A Linux patch is posted as well, but I think it's worth to make pvpanic
useable on old guests at the price of three lines and few bytes of SSDT.

The old _STA method was
  Method (_STA, 0, NotSerialized) {
      Store (PEST, Local0)
      If (LEqual (Local0, Zero)) {
          Return (Zero) }
      Else {
          Return (0x0F) }}

Igor pointed out that we don't need to use a method to return a constant
and that 0xB (don't show in UI) is the common definition now.

Also, the device used to be PEVT.  (PEVT as in "panic event"?)

use_virtcon, use_sclp, no_floppy, no_cdrom, default_display,
compat_props, and hw_version.

b6b5c8e492 pc: Define MACHINE_OPTIONS macros consistently for all machines
Define a MACHINE_OPTIONS macro for each PC machine, and move every field
inside the QEMUMachine structs to the macros, except for name, init, and
compat_props.

This also ensures that all MACHINE_OPTIONS inherit the fields from the
next version, so their definitions carry only the changes that exist
between one version and the next one.

Comments about specific cases:

pc-*-2.1:

  Existing PC_*_2_1_MACHINE_OPTIONS macros were defined as:
      PC_*_MACHINE_OPTIONS,
      .default_machine_opts = "firmware=bios-256k.bin"

  PC_*_2_2_MACHINE_OPTIONS is:
      PC_*_2_3_MACHINE_OPTIONS
  which is expanded to:
      PC_*_MACHINE_OPTIONS,
      .default_machine_opts = "firmware=bios-256k.bin",
      .default_display = "std"

  The only difference between 2_1 and 2_2 is .default_display, that's why
  we didn't reuse PC_*_2_2_MACHINE_OPTIONS. The good news is that having
  multiple initializers for a field is allowed by C99, and the last
  initializer overrides the previous ones.

  So we can reuse the 2_2 macro in 2_1 and define PC_*_2_1_MACHINE_OPTIONS
  as:
      PC_*_2_2_MACHINE_OPTIONS,
      .default_display = NULL

pc-*-1.7:

  PC_*_1_7_MACHINE_OPTIONS was defined as:
      PC_*_MACHINE_OPTIONS

  PC_*_2_0_MACHINE_OPTIONS is defined as:
      PC_*_2_1_MACHINE_OPTIONS
  which is expanded to:
      PC_*_2_2_MACHINE_OPTIONS,
      .default_display = NULL
  which is expanded to:
      PC_*_2_3_MACHINE_OPTIONS,
      .default_display = NULL
  which is expanded to:
      PC_*_MACHINE_OPTIONS,
      .default_machine_opts = "firmware=bios-256k.bin",
      .default_display = "std",
      .default_display = NULL  /* overrides the previous line */

  So, the only difference between PC_*_1_7_MACHINE_OPTIONS and
  PC_*_2_0_MACHINE_OPTIONS is .default_machine_opts (as .default_display
  is not explicitly set by PC_*_MACHINE_OPTIONS so it is NULL).

  So we can keep the macro reuse pattern and define
  PC_*_2_0_MACHINE_OPTIONS as:
      PC_*_2_0_MACHINE_OPTIONS,
      .default_machine_opts = NULL

pc-*-2.4 (alias and is_default fields):

  Set alias and is_default fields inside the 2.4 MACHINE_OPTIONS macro,
  and clear it in the 2.3 macro (that reuses the 2.4 macro).

hw_machine:

  As all the machines older than v1.0 set hw_version explicitly, we can
  safely move the field to the MACHINE_OPTIONS macros without affecting
  the other versions that reuse them.

init function:

  Some machines had the init function set inside the MACHINE_OPTIONS
  macro. Move it to the QEMUMachine declaration, to keep it consistent
  with the other machines.
