They are QMP events, not monitor events. Rename them accordingly.
Also, move bdrv_emit_qmp_error_event() up in the file. A new event will
be added soon and it's good to have them next each other.

As we make upper bits in IO and prefetcheable memory
registers writeable, we should declare support
for 64 bit prefetcheable memory and 32 bit io
in the bridge.
This changes the default for apb, dec, but I'm guessing
they got the defaults wrong by accident.
Alternatively, we could let bridges declare lack of
64 bit support and make the upper bits read-only zero.
With this applied, we can drop these bits
from express code.

pci_regs.h specifies many registers by mask +
shifted register values.
There's always some duplication when using such:
for example to override device type, we would need:
pci_word_test_and_clear_mask(cap + PCI_EXP_FLAGS,
PCI_EXP_FLAGS_TYPE);
pci_word_test_and_set_mask(cap + PCI_EXP_FLAGS,
PCI_EXP_TYPE_ENDPOINT << (ffs(PCI_EXP_FLAGS_TYPE) - 1));
Getting such registers also uses some duplication:
word = pci_get_word(cap + PCI_EXP_FLAGS) & PCI_EXP_FLAGS_TYPE;
if ((word >> ffs((PCI_EXP_FLAGS_TYPE) - 1)) == PCI_EXP_TYPE_ENDPOINT)
Add API to access such registers in one line:
pci_set_word_by_mask(cap + PCI_EXP_FLAGS, PCI_EXP_FLAGS_TYPE,
PCI_EXP_TYPE_ENDPOINT)
and
word = pci_get_word_by_mask(cap + PCI_EXP_FLAGS, PCI_EXP_FLAGS_TYPE)
if (word == PCI_EXP_TYPE_ENDPOINT)

Now, the pc-sysfw:rom_only property will default
to false which enables flash by default.
All pc types below pc-1.1 set rom_only to true.
This prevents flash from being enabled on these
pc machine types.
For pc-1.1 rom_only will use the default (false),
which will allow flash to be used for pc-1.1.

Flash can be enabled by calling pc_system_firmware_init
with the system_flash_enabled parameter being non-zero.
If system_flash_enabled is zero, then the older qemu
rom creation method will be used.
If flash is enabled and a pflash image is found, then
it is used for the system firmware image.
If flash is enabled and a pflash image is not initially
found, then a read-only pflash device is created using
the -bios filename.
KVM cannot execute from a pflash region currently.
Therefore, when KVM is enabled, the old rom based
initialization method is used.

Hex properties are an obstacle to removal of old qdev string parsing, but
even here we can lay down the foundations for future simplification. In
general, they are rarely used and their printed form is more interesting
than the parsing. For example you'd usually set isa-serial.index
instead of isa-serial.iobase. And luckily our main client, libvirt
only cares about few of these, and always sets them with a 0x prefix.
So the series stops accepting bare hexadecimal numbers, preparing for
making legacy properties read-only in 1.3 or so. The read side will
stay as long as "info qtree" is with us.

Visitors allow a limited form of polymorphism. Exploit it to support

This patch fixes the local qxl renderer to not kick spice-server
in case the vm is stopped. First it is largely pointless because
we ask spice-server to process all not-yet processed commands when
the vm is stopped, so there isn't much do do anyway. Second we
avoid triggering an assert in spice-server.
The patch makes sure we still honor redraw requests, even if we don't
ask spice-server for updates. This is needed to handle displaysurface
changes with a stopped vm correctly.
With this patch applied it is possible to take screen shots (via
screendump monitor command) from a qxl gpu even in case the guest
is stopped.

This enables acceleration for MMIO-based TPR registers accesses of
32-bit Windows guest systems. It is mostly useful with KVM enabled,
either on older Intel CPUs (without flexpriority feature, can also be
manually disabled for testing) or any current AMD processor.
The approach introduced here is derived from the original version of
qemu-kvm. It was refactored, documented, and extended by support for
user space APIC emulation, both with and without KVM acceleration. The
VMState format was kept compatible, so was the ABI to the option ROM
that implements the guest-side para-virtualized driver service. This
enables seamless migration from qemu-kvm to upstream or, one day,
between KVM and TCG mode.
The basic concept goes like this:
- VAPIC PV interface consisting of I/O port 0x7e and (for KVM in-kernel
irqchip) a vmcall hypercall is registered
- VAPIC option ROM is loaded into guest
- option ROM activates TPR MMIO access reporting via port 0x7e
- TPR accesses are trapped and patched in the guest to call into option
ROM instead, VAPIC support is enabled
- option ROM TPR helpers track state in memory and invoke hypercall to
poll for pending IRQs if required

This will allow the APIC core to file a TPR access report. Depending on
the accelerator and kernel irqchip mode, it will either be delivered
right away or queued for later reporting.
In TCG mode, we can restart the triggering instruction and can therefore
forward the event directly. KVM does not allows us to restart, so we
postpone the delivery of events recording in the user space APIC until
the current instruction is completed.
Note that KVM without in-kernel irqchip will report the address after
the instruction that triggered the access.

Instead of providing 4 individual query functions for mode, gate, output
and initial counter state, introduce a service that queries all
information at once. This comes with tiny additional costs for
pcspk_callback but with a much cleaner interface. Also, it will simplify

When the HPET enters legacy mode, the IRQ output of the PIT is
suppressed and replaced by the HPET timer 0. But the current code to
emulate this was broken in many ways. It reset the PIT state after
re-enabling, it worked against a stale static PIT structure, and it did
not properly saved/restored the IRQ output mask in the PIT vmstate.
This patch solves the PIT IRQ control in a different way. On x86, it
both redirects the PIT IRQ to the HPET, just like the RTC. But it also
keeps the control line from the HPET to the PIT. This allows to disable
the PIT QEMU timer when it is not needed. The PIT's view on the control
line state is now saved in the same format that qemu-kvm is already
using.
Note that, in contrast to the suppressed RTC IRQ line, we do not need to
save/restore the PIT line state in the HPET. As we trigger a PIT IRQ
update via the control line, the line state is reconstructed on mode
switch.

HPET legacy emulation will require control over the PIT IRQ output. To
enable this, add support for an alternative IRQ output object to the PIT
factory function. If the isa_irq number is < 0, this object will be
used.
This also removes the IRQ number property from the PIT class as we now
use a generic GPIO output pin that is connected by the factory function.

In legacy mode, the HPET suppresses the RTC interrupt delivery via IRQ
8 but keeps track of the RTC output level and applies it when legacy
mode is turned off again. This value has to be preserved across save/
restore as it cannot be reconstructed otherwise.
To document that a raised rtc_irq_level won't survive a vmload without
a hpet/rtc_irq_level subsection, add an explicit clearing to the reset
handler.

Since QOM'ification, qdev_try_create() uses object_new() internally,
which asserts "type != NULL" when the type is not registered.
This was revealed by the combination of kvmclock's kvm_enabled() check
and early QOM type registration.
Check whether the class exists before calling object_new(), so that
the caller (e.g., qdev_create) can fail gracefully, telling us which
device could not be created.
