This patch series is a follow-up of my previous patch
"[PATCH v4] hw/rtc/mc146818rtc: Make this rtc device target independent".
It has now been split into multiple patches to ease the review, and some
further patches have been added on top.
The basic idea is to change hw/rtc/mc146818rtc.c into tar
We want to get rid of the "#ifdef TARGET_I386" statements in the mc146818
code, so we need a different way to decide whether the slew tick policy
is available or not. Introduce a new property "slew-tick-policy-available"
which can be set by the machines that support this tick policy.

The only reason for this code being target dependent was the IRQ-counting
related code in rtc_policy_slew_deliver_irq(). Since these functions have
been moved into a new, separate file (kvm_irqcount.c) which is now always
compiled and linked if either APIC or the mc146818 device are required,
and s
The 'slew' lost tick policy is only available on systems with a mc146818
RTC. On other systems, "-rtc driftfix=slew" is currently silently ignored.
Let's emit at least a warning in this case to make the users aware that
there is something wrong in their command line settings.

These IRQ counting functions will soon be required in binaries that
do not include the APIC code, too, so let's extract them into a
separate file that can be linked independently of the APIC code.
While we're at it, change the apic_* prefix into kvm_* since the
functions are used from the i8259 PI

Manually implement a socketpair() function, using UNIX sockets and
simple peer credential checking.
QEMU doesn't make much use of socketpair, beside vhost-user which is not
available for win32 at this point. However, I intend to use it for
writing some new portable tests.

Hi,
The following series first fixes a few tests on win32. The second part focuses
on 'add_client' support, by limiting its scope to sockets and adding win32
support. Finally, it enables vnc-display test on win32, to exercise the new code
paths and demonstrate its usage.

Whether it is SPICE, VNC, D-Bus, or the socket chardev, they all
actually expect a socket kind or will fail in different ways at runtime.

Hi,
this is with QEMU-7.2.

Hi Ira,

The specific problem I'm trying to solve is the location and
representation of the coprocessor register hash table for ARM cpus,
but in the process affects how cpu initialization might be done for
all targets.
At present, each cpu (for all targets) is initialized separately.
For some, like ARM, we
These properties apply to the class itself, as opposed to
object_class_property_* in which the property is attached
to the class but applies to each object instance.
Apply global properties via a class_late_init on DeviceClass.

With the movement of the properties, we can remove the has_mpu field
from the cpu entirely, using only the class. The pmsav7_dregion field
must stay in the cpu to handle the usage with VMSTATE_VARRAY_UINT32.

Rather than call arm_cpu_post_init ourselves from the
object instance_init, let QOM handle this.

With the introduction of aarch64_host_class_init, we have
enough feature bits set to do propagation early. Move the
tcg consistency checks to class_late_init, after we have
populated all of the id registers.

Rename to arm_build_mp_affinity. This frees up the name for
other usage, and emphasizes that the cpu object is not involved.
