The N1 chiplet handle the high speed i/o traffic over PCIe and others.
The N1 chiplet consists of PowerBus Fabric controller,
nest Memory Management Unit, chiplet control unit and more.
This commit creates a N1 chiplet model and initialize and realize the
pervasive chiplet model where chiplet control registers are implemented.
This commit also implement the read/write method for the powerbus scom

A POWER10 chip is divided into logical units called chiplets. Chiplets
are broadly divided into "core chiplets" (with the processor cores) and
"nest chiplets" (with everything else). Each chiplet has an attachment
to the pervasive bus (PIB) and with chiplet-specific registers. All nest
chiplets have a common basic set of registers and This model will provide
the registers functionality for common registers of nest chiplet (Pervasive
Chiplet, PB Chiplet, PCI Chiplets, MC Chiplet, PAU Chiplets)
This commit implement the read/write functions of chiplet control registers.

The QEMU I2C buses and devices use the resettable
interface for resetting while the PNV I2C controller
and parent buses and devices have not yet transitioned
to this new interface and use the old reset strategy.
This was preventing the I2C buses and devices wired
to the PNV I2C controller from being reset.
The short term fix for this is to have the PNV I2C
Controller's reset function explicitly call the resettable
interface function, bus_cold_reset(), on all child
I2C buses.
The long term fix should be to transition all PNV parent
devices and buses to use the resettable interface so that
all child buses and devices are automatically reset.

For power10-rainier, a pca9552 device is used for PCIe slot hotplug
power control by the Power Hypervisor code. The code expects that
some time after it enables power to a PCIe slot by asserting one of
the pca9552 GPIO pins 0-4, it should see a "power good" signal asserted
on one of pca9552 GPIO pins 5-9.
To simulate this behavior, we simply connect the GPIO outputs for
pins 0-4 to the GPIO inputs for pins 5-9.
Each PCIe slot is assigned 3 GPIO pins on the pca9552 device, for
control of up to 5 PCIe slots. The per-slot signal names are:
SLOTx_EN.......PHYP uses this as an output to enable
slot power. We connect this to the
SLOTx_PG pin to simulate a PGOOD signal.
SLOTx_PG.......PHYP uses this as in input to detect
PGOOD for the slot. For our purposes
we just connect this to the SLOTx_EN
output.
SLOTx_Control..PHYP uses this as an output to prevent
a race condition in the real hotplug
circuitry, but we can ignore this output
for simulation.

Allow external devices to drive pca9552 input pins by adding
input GPIO's to the model. This allows a device to connect
its output GPIO's to the pca9552 input GPIO's.
In order for an external device to set the state of a pca9552
pin, the pin must first be configured for high impedance (LED
is off). If the pca9552 pin is configured to drive the pin low
(LED is on), then external input will be ignored.
Here is a table describing the logical state of a pca9552 pin
given the state being driven by the pca9552 and an external device:
PCA9552

State
| Hi-Z | Low |

The pca9552 INPUT0 and INPUT1 registers are supposed to

should be seen in the INPUT0/1 registers for a pin when
its corresponding LSn bits are set to 0, which is also
the state needed for turning on an LED in a typical

and setting INPUT0/1 bit to a 1 when the LSn bit was

Fortunately most of these registers are obscure and/or have not been
correctly implemented in the gdb server (e.g., DEC, TB, CFAR), so risk
of breaking users should be low.
QEMU should follow the ISA for register name convention (where there is
no established GDB name).

is_prefix_insn_excp() loads the first word of the instruction address
which caused an exception, to determine whether or not it was prefixed
so the prefix bit can be set in [H]SRR1.
This works if the instruction image can be loaded, but if the exception
was caused by an ifetch, this load could fail and cause a recursive
exception and crash. Machine checks caused by ifetch are not excluded
from the prefix check and can crash (see issue 2108 for an example).
Fix this by excluding machine checks caused by ifetch from the prefix

Python is transitioning to a world where you're not allowed to use 'pip

use of pip clashing with distro provided python packages, which creates
a major headache on distro upgrades.
All our CI environments, however, are 100% disposable so the upgrade
headaches don't exist. Thus we can undo the python defaults to allow

MSYS2 is dropping support for 32-bit Windows. This shows up for us
as various packages we were using in our CI job no longer being
available to install, which causes the job to fail. In commit
8e31b744fd we dropped the dependency on libusb and spice, but the
dtc package has also now been removed.
For us as QEMU upstream, "32 bit x86 hosts for system emulation" have
already been deprecated as of QEMU 8.0, so we are ready to drop them
anyway.
Drop the msys2-32bit CI job, as the first step in doing this.
This is cc'd to stable, because this job will also be broken for CI
on the stable branches. We can't drop 32-bit support entirely there,
but we will still be covering at least compilation for 32-bit Windows
via the cross-win32-system job.

include/hw/ide/internal.h is currently included by include/hw/ide/pci.h
and thus exposed to a lot of files that are not part of the IDE subsystem.
Stop including internal.h there and use the appropriate new headers
ide-bus.h and ide-dma.h instead.

There was only one prototype left in this legacy file. Move it to

qdev.c is a mixture between IDE bus specific functions and IDE device
functions. Let's split it up to make it more obvious which part is
related to bus handling and which part is related to device handling.

For distros like downstream RHEL, it would be helpful to allow to disable
the CompactFlash device. For making this possible, we need a separate
Kconfig switch for this device, and the code should reside in a separate
file. Let's also introduce a new header ide-dev.h which can be used to
collect definitions related to IDE devices.

The interrupt handlers need to be populated before the device is realized since
internal devices such as the RTC are wired during realize(). If the interrupt
handlers aren't populated, devices such as the RTC will be wired with a NULL
interrupt handler, i.e. MC146818RtcState::irq is NULL.
