6da68df7f9 hw/arm/nseries: Replace the bluetooth chardev with a "null" chardev
We are going to remove the bitrotten bluetooth backend, so we can
not use it in the n800 and n810 machines anymore. Replace the chardev
here with a "null" chardev and stop including the "hw/bt.h" header.

I am not aware of a full working N8x0 environment that can be used to
test these machines, but the Linux kernel from the Meego project that
can be found on http://stskeeps.subnetmask.net/meego-n8x0/ still seems
to boot as far as it did before.

d32dc61421 hw/mips: Deprecate the r4k machine
The r4k machine was introduced in 2005 (6af0bf9c7) and its last
logical change was in 2005 (9542611a6). After that, one can
count 164 maintenance commits (QEMU API changes) with the
exception of 1 fix in 2015 (memory leak, commit 3ad9fd5a).

This machine was introduced as a proof of concept to run a MIPS
CPU. Two years later, the Malta machine was added (commit
5856de80), modeling a real platform.

Note also this machine has no specification except 5 lines in
the header of this file:

 * emulates a simple machine with ISA-like bus.
 * ISA IO space mapped to the 0x14000000 (PHYS) and
 * ISA memory at the 0x10000000 (PHYS, 16Mb in size).
 * All peripherial devices are attached to this "bus" with
 * the standard PC ISA addresses.

The Linux kernel support for this machine has been dropped more
than 10 years ago in commit 302922e5.

It is time to deprecate this obsolete machine. Users are
recommended to use the Malta board, and its hardware is well
documented.

310b5bc692 aspeed/scu: Fix W1C behavior
This models the clock write one to clear registers, and fixes up some
incorrect behavior in all of the write to clear registers.

There was also a typo in one of the register definitions.

545d6bef70 aspeed/i2c: Add support for DMA transfers
The I2C controller of the Aspeed AST2500 and AST2600 SoCs supports DMA
transfers to and from DRAM.

A pair of registers defines the buffer address and the length of the
DMA transfer. The address should be aligned on 4 bytes and the maximum
length should not exceed 4K. The receive or transmit DMA transfer can
then be initiated with specific bits in the Command/Status register of
the controller.

6054fc73e8 aspeed/i2c: Add support for pool buffer transfers
The Aspeed I2C controller can operate in different transfer modes :

  - Byte Buffer mode, using a dedicated register to transfer a
    byte. This is what the model supports today.

  - Pool Buffer mode, using an internal SRAM to transfer multiple
    bytes in the same command sequence.

Each SoC has different SRAM characteristics. On the AST2400, 2048
bytes of SRAM are available at offset 0x800 of the controller AHB
window. The pool buffer can be configured from 1 to 256 bytes per bus.

On the AST2500, the SRAM is at offset 0x200 and the pool buffer is of
16 bytes per bus.

On the AST2600, the SRAM is at offset 0xC00 and the pool buffer is of
32 bytes per bus. It can be splitted in two for TX and RX but the
current model does not add support for it as it it unused by known
drivers.

1625073289 exynos4210_gic: Suppress gcc9 format-truncation warnings
exynos4210_gic_realize() prints the number of cpus into some temporary
buffers, but it only allows 3 bytes space for it.  That's plenty:
existing machines will only ever set this value to EXYNOS4210_NCPUS
(2).  But the compiler can't always figure that out, so some[*] gcc9
versions emit -Wformat-truncation warnings.

We can fix that by hinting the constraint to the compiler with a
suitably placed assert().

[*] The bizarre thing here, is that I've long gotten these warnings
    compiling in a 32-bit x86 container as host - Fedora 30 with
    gcc-9.2.1-1.fc30.i686 - but it compiles just fine on my normal
    x86_64 host - Fedora 30 with and gcc-9.2.1-1.fc30.x86_64.

No caller actually passes null.

Fix anyway: splice in a local Error *err, and error_propagate().

5f2585772f virtio-blk: advertise F_WCE (F_FLUSH) if F_CONFIG_WCE is advertised
Virtio spec 1.1 (and earlier), 5.2.5.2 Driver Requirements: Device
Initialization:

"Devices SHOULD always offer VIRTIO_BLK_F_FLUSH, and MUST offer it if
they offer VIRTIO_BLK_F_CONFIG_WCE"

Currently F_CONFIG_WCE and F_WCE are not connected to each other.
Qemu will advertise F_CONFIG_WCE if config-wce argument is
set for virtio-blk device. And F_WCE is advertised only if
underlying block backend actually has it's caching enabled.

Fix this by advertising F_WCE if F_CONFIG_WCE is also advertised.

To preserve backwards compatibility with newer machine types make this
behaviour governed by "x-enable-wce-if-config-wce" virtio-blk-device
property and introduce hw_compat_4_2 with new property being off by
default for all machine types <= 4.2 (but don't introduce 4.3
machine type itself yet).

This change does not break live migration compatibility since
vhost-user-fs-pci devices are not migratable yet.

5a0948d36c net/virtio: Fix failover error handling crash bugs
Functions that take an Error ** parameter to pass an error to the
caller expect the parameter to point to null.
failover_replug_primary() violates this precondition in several
places:

* After qemu_opts_from_qdict() failed, *errp is no longer null.
  Passing it to error_setg() is wrong, and will trip the assertion in
  error_setv().  Messed up in commit 150ab54aa6 "net/virtio: fix
  re-plugging of primary device".  Simply drop the error_setg().

* Passing @errp to qemu_opt_set_bool(), hotplug_handler_pre_plug(),
  and hotplug_handler_plug() is wrong.  If one of the first two fails,
  *errp is no longer null.  Risks tripping the same assertion.
  Moreover, continuing after such errors is unsafe.  Messed up in
  commit 9711cd0dfc "net/virtio: add failover support".  Fix by
  handling each error properly.

failover_replug_primary() crashes when passed a null @errp.  Also
messed up in commit 9711cd0dfc.  This bug can't bite as no caller
actually passes null.  Fix it anyway.

4dbac1aed2 net/virtio: Drop useless n->primary_dev not null checks
virtio_net_handle_migration_primary() returns early when it can't
ensure n->primary_dev is non-null.  Checking it again right after that
early return is redundant.  Drop.

If n->primary_dev is null on entering failover_replug_primary(), @pdev
will become null, and pdev->partially_hotplugged will crash.  Checking
n->primary_dev later is useless.  It can't actually be null, because
its caller virtio_net_handle_migration_primary() ensures it isn't.

6cf80f90c4 mos6522: update counters when timer interrupts are off
Even if the interrupts are off, counters must be updated because
they are running anyway and kernel can try to read them

b14848f5d7 spapr: Work around spurious warnings from vfio INTx initialization
Traditional PCI INTx for vfio devices can only perform well if using
an in-kernel irqchip.  Therefore, vfio_intx_update() issues a warning
if an in kernel irqchip is not available.

We usually do have an in-kernel irqchip available for pseries machines
on POWER hosts.  However, because the platform allows feature
negotiation of what interrupt controller model to use, we don't
currently initialize it until machine reset.  vfio_intx_update() is
called (first) from vfio_realize() before that, so it can issue a
spurious warning, even if we will have an in kernel irqchip by the
time we need it.

To workaround this, make a call to spapr_irq_update_active_intc() from
spapr_irq_init() which is called at machine realize time, before the
vfio realize.  This call will be pretty much obsoleted by the later
call at reset time, but it serves to suppress the spurious warning
from VFIO.

e532e1d93c spapr: Handle irq backend changes with VFIO PCI devices
pseries machine type can have one of two different interrupt controllers in
use depending on feature negotiation with the guest.  Usually this is
invisible to devices, because they route to a common set of qemu_irqs which
in turn dispatch to the correct back end.

VFIO passthrough devices, however, wire themselves up directly to the KVM
irqchip for performance, which means they are affected by this change in
interrupt controller.  To get them to adjust correctly for the change in
irqchip, we need to fire the kvm irqchip change notifier.

c5478fea27 vfio/pci: Respond to KVM irqchip change notifier
VFIO PCI devices already respond to the pci intx routing notifier, in order
to update kernel irqchip mappings when routing is updated.  However this
won't handle the case where the irqchip itself is replaced by a different
model while retaining the same routing.  This case can happen on
the pseries machine type due to PAPR feature negotiation.

To handle that case, add a handler for the irqchip change notifier, which
does much the same thing as the routing notifier, but is unconditional,
rather than being a no-op when the routing hasn't changed.
