The ibm,purr and ibm,spurr device tree properties are used to indicate
that the processor implements the Processor Utilisation of Resources
Register (PURR) and Scaled Processor Utilisation of Resources Registers
(SPURR), respectively. Each property has a single value which represents
the level of architecture supported. A value of 1 for ibm,purr means
support for the version of the PURR defined in book 3 in version 2.02 of
the architecture. A value of 1 for ibm,spurr means support for the
version of the SPURR defined in version 2.05 of the architecture.
Add these properties for all processors for which the PURR and SPURR
registers are generated.

As explained in commit aff39be0ed97:
Both functions, object_initialize() and object_property_add_child()
increase the reference counter of the new object, so one of the
references has to be dropped afterwards to get the reference
counting right. Otherwise the child object will not be properly
cleaned up when the parent gets destroyed.
Thus let's use now object_initialize_child() instead to get the
reference counting here right.
This patch was generated using the following Coccinelle script:
@use_sysbus_init_child_obj_missing_parent@
expression child_ptr;
expression child_type;
expression child_size;
@@
- object_initialize(child_ptr, child_size, child_type);
...

...
?- object_unref(OBJECT(child_ptr));
+ sysbus_init_child_obj(OBJECT(PARENT_OBJ), "CHILD_NAME", child_ptr,
+ child_size, child_type);
We let NVIC adopt the SysTick timer.
While the object_initialize() function doesn't take an
'Error *errp' argument, the object_initialize_child() does.
Since this code is used when a machine is created (and is not
yet running), we deliberately choose to use the &error_abort
argument instead of ignoring errors if an object creation failed.
This choice also matches when using sysbus_init_child_obj(),
since its code is:
void sysbus_init_child_obj(Object *parent,
const char *childname, void *child,
size_t childsize, const char *childtype)
{
object_initialize_child(parent, childname, child, childsize,
childtype, &error_abort, NULL);

Since this code is used when a machine is created (and is not

As explained in commit aff39be0ed97:
Both functions, object_initialize() and object_property_add_child()
increase the reference counter of the new object, so one of the
references has to be dropped afterwards to get the reference
counting right. Otherwise the child object will not be properly
cleaned up when the parent gets destroyed.
Thus let's use now object_initialize_child() instead to get the
reference counting here right.

The ICC_CTLR_EL3 register includes some bits which are aliases
of bits in the ICC_CTLR_EL1(S) and (NS) registers. QEMU chooses
to keep those bits in the cs->icc_ctlr_el1[] struct fields.
Unfortunately a missing '~' in the code to update the bits
in those fields meant that writing to ICC_CTLR_EL3 would corrupt
the ICC_CLTR_EL1 register values.

The current codebase is not specific about the endianess of the
fw_cfg 'file' entry 'reboot-timeout'.
Per docs/specs/fw_cfg.txt:
=== All Other Data Items ===
Please consult the QEMU source for the most up-to-date
and authoritative list of selector keys and their respective
items' purpose, format and writeability.
Checking the git history, this code was introduced in commit
ac05f34924, very similar to commit 3d3b8303c6 for the
'boot-menu-wait' entry, which explicitely use little-endian.
OVMF consumes 'boot-menu-wait' as little-endian, however it does
not consume 'reboot-timeout'.
Regarding the git history and OVMF use, we choose to explicit
'reboot-timeout' endianess as little-endian.

pci_bus_is_root() currently relies on a method in the PCIBusClass.
But it's always known if a PCI bus is a root bus when we create it, so
using a dynamic method is overkill.
This replaces it with an IS_ROOT bit in a new flags field, which is set on
root buses and otherwise clear. As a bonus this removes the special
is_root logic from pci_expander_bridge, since it already creates its bus
as a root bus.

Dummy table (with signature "QEMU") creation came from original SeaBIOS
codebase. And QEMU would have to keep it around if there were Q35 machine
that depended on keeping ACPI tables blob constant size. Luckily there
were no versioned Q35 machine types before commit:
(since 2.3) a1666142db acpi-build: make ROMs RAM blocks resizeable
which obsoleted need to keep ACPI tables blob the same size on source/destination.
Considering the 1st versioned machine is pc-q35-2.4, the dummy table
is not really necessary and it's safe to drop it without breaking
cross version migration in both directions unconditionally.

A number of virtio devices (gpu, crypto, mouse, keyboard, tablet) only
support the virtio-1 (aka modern) mode. Currently if the user launches
QEMU, setting those devices to enable legacy mode, QEMU will silently
create them in modern mode, ignoring the user's (mistaken) request.
This patch introduces proper data validation so that an attempt to
configure a virtio-1-only devices in legacy mode gets reported as an
error to the user.
Checking this required introduction of a new field to explicitly track
what operating model is to be used for a device, separately from the
disable_modern and disable_legacy fields that record the user's
requested configuration.

The ne2000.c file contains functions common the the ISA and PCI
devices. To allow to build with one or another, extract the PCI
specific part into a new file.
This fix an issue where the NE2000_ISA Kconfig had to pull the
full PCI core objects.

In our downstream distribution of QEMU, we'd like to ship the binary
without the multi-serial PCI devices. To make this disablement easier,
let's move the devices into a separate file and add a proper Kconfig-
switch for these devices.

It was found that Hyper-V 2016 on KVM in some configurations (q35 machine +
piix4-usb-uhci) hangs on boot. Root-cause was that one of Hyper-V
level-triggered interrupt handler performs EOI before fixing the cause of
the interrupt. This results in IOAPIC keep re-raising the level-triggered
interrupt after EOI because irq-line remains asserted.
Gory details: https://www.spinics.net/lists/kvm/msg184484.html
(the whole thread).
Turns out we were dealing with similar issues before; in-kernel IOAPIC
implementation has commit 184564efae4d ("kvm: ioapic: conditionally delay
irq delivery duringeoi broadcast") which describes a very similar issue.
Steal the idea from the above mentioned commit for IOAPIC implementation in
QEMU. SUCCESSIVE_IRQ_MAX_COUNT, delay and the comment are borrowed as well.

Commit 72c194f7e7 added a non-null check on the 'obj' pointer.
Later, commit 500b11ea50 added code which uses the 'obj'
pointer _before_ the assertion check. Move the assertion
_before_ the pointer use.

When building with CONFIG_Q35=n, we get:
LINK x86_64-softmmu/qemu-system-x86_64
/usr/bin/ld: hw/i386/acpi-build.o: in function `acpi_get_misc_info':
/source/qemu/hw/i386/acpi-build.c:243: undefined reference to `ich9_lpc_find'
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:204: qemu-system-x86_64] Error 1
This is due to a dependency in acpi-build.c on the ICH9_LPC
(via ich9_lpc_find) and PIIX4_PM (via piix4_pm_find) devices.
To allow better modularity (compile acpi-build.c with only
Q35/ICH9 or ISAPC/PIIX4), refactor the similar helper as
object_resolve_type_unambiguous(). This way we relax the
linker dependencies and can build the x86 targets with a
selection of machines (instead of all of them).

In situations where e1000 receives an undersized Ethernet frame,
QEMU increments the emulated "Receive Undersize Count (RUC)"
register when padding the frame.
This is incorrect because this an expected scenario (e.g. with
VLAN tag stripping) and not an error. As such, QEMU should not
increment the emulated RUC.

We used to set backend unconditionally, this won't work for some
guests (e.g windows driver) who may not initialize all virtqueues. For
kernel backend, this will fail since it may try to validate the rings
during setting backend.
Fixing this by simply skipping the backend set when we find desc is
not ready.

The leon3 board is looking for u-boot.bin by default (LEON3_PROM_FILENAME)..
But in the case this file is not found and no other file are given on the
command line we get the following error:
$ ./qemu-system-sparc -M leon3_generic
qemu-system-sparc: Can't read bios image (null)
So use LEON3_PROM_FILENAME instead of filename in case it is NULL to get a
less cryptic message:
$ ./qemu-system-sparc -M leon3_generic
qemu-system-sparc: Can't read bios image 'u-boot.bin'

The SCC/ESCC will briefly stop asserting an interrupt when the
transmit FIFO is filled.
This code doesn't model the transmit FIFO/shift register so the
pending transmit interrupt is never deasserted which means that an
edge-triggered interrupt controller will never see the low-to-high
transition it needs to raise another interrupt. The practical
consequence of this is that guest firmware with an interrupt service
routine for the ESCC that does not send all of the data it has
immediately will stop sending data if the following sequence of
events occurs:
1. Disable processor interrupts
2. Write a character to the ESCC
3. Add additional characters to a buffer which is drained by the ISR
4. Enable processor interrupts
In this case, the first character will be sent, the interrupt will
fire and the ISR will output the second character. Since the pending
transmit interrupt remains asserted, no additional interrupts will
ever fire.
This behavior was triggered by firmware for an embedded system with a
Z85C30 which necessitated this patch.
This patch fixes that situation by explicitly lowering the IRQ when a
character is written to the buffer and no other interrupts are currently
pending.
