a64508304e lasi: fix RTC migration
Migrate rtc_ref (which only needs to be 32-bit because it is summed to
a 32-bit register), which requires bumping the migration version.
The HPPA machine does not have versioned machine types so it is okay
to block migration to old versions of QEMU.

While at it, drop the write-only field rtc from LasiState.

4c921e3fb2 hw/mips/itu: Pass SAAR using QOM link property
QOM objects shouldn't access each other internals fields
except using the QOM API.

mips_cps_realize() instantiates a TYPE_MIPS_ITU object, and
directly sets the 'saar' pointer:

   if (saar_present) {
       s->itu.saar = &env->CP0_SAAR;
   }

In order to avoid that, pass the MIPS_CPU object via a QOM
link property, and set the 'saar' pointer in mips_itu_realize().

883f2c591f bulk: Rename TARGET_FMT_plx -> HWADDR_FMT_plx
The 'hwaddr' type is defined in "exec/hwaddr.h" as:

    hwaddr is the type of a physical address
   (its size can be different from 'target_ulong').

All definitions use the 'HWADDR_' prefix, except TARGET_FMT_plx:

 $ fgrep define include/exec/hwaddr.h
 #define HWADDR_H
 #define HWADDR_BITS 64
 #define HWADDR_MAX UINT64_MAX
 #define TARGET_FMT_plx "%016" PRIx64
         ^^^^^^
 #define HWADDR_PRId PRId64
 #define HWADDR_PRIi PRIi64
 #define HWADDR_PRIo PRIo64
 #define HWADDR_PRIu PRIu64
 #define HWADDR_PRIx PRIx64
 #define HWADDR_PRIX PRIX64

Since hwaddr's size can be *different* from target_ulong, it is
very confusing to read one of its format using the 'TARGET_FMT_'
prefix, normally used for the target_long / target_ulong types:

$ fgrep TARGET_FMT_ include/exec/cpu-defs.h
 #define TARGET_FMT_lx "%08x"
 #define TARGET_FMT_ld "%d"
 #define TARGET_FMT_lu "%u"
 #define TARGET_FMT_lx "%016" PRIx64
 #define TARGET_FMT_ld "%" PRId64
 #define TARGET_FMT_lu "%" PRIu64

Apparently this format was missed during commit a8170e5e97
("Rename target_phys_addr_t to hwaddr"), so complete it by
doing a bulk-rename with:

 $ sed -i -e s/TARGET_FMT_plx/HWADDR_FMT_plx/g $(git grep -l TARGET_FMT_plx)

592f0a9429 hw/{misc, riscv}: pfsoc: add system controller as unimplemented
The system controller on PolarFire SoC is access via a mailbox. The
control registers for this mailbox lie in the "IOSCB" region & the
interrupt is cleared via write to the "SYSREG" region. It also has a
QSPI controller, usually connected to a flash chip, that is used for
storing FPGA bitstreams and used for In-Application Programming (IAP).

Linux has an implementation of the system controller, through which the
hwrng is accessed, leading to load/store access faults.

Add the QSPI as unimplemented and a very basic (effectively
unimplemented) version of the system controller's mailbox. Rather than
purely marking the regions as unimplemented, service the mailbox
requests by reporting failures and raising the interrupt so a guest can
better handle the lack of support.

13cd1d6eaf hw/misc: pfsoc: add fabric clocks to ioscb
On PolarFire SoC, some peripherals (eg the PCI root port) are clocked by
"Clock Conditioning Circuitry" in the FPGA. The specific clock depends
on the FPGA bitstream & can be locked to one particular {D,P}LL - in the
Icicle Kit Reference Design v2022.09 or later this is/will be the case.

Linux v6.1+ will have a driver for this peripheral and devicetrees that
previously relied on "fixed-frequency" clock nodes have been switched
over to clock-controller nodes. The IOSCB region is represented in QEMU,
but the specific region of it that the CCCs occupy has not so v6.1-rcN
kernels fail to boot in QEMU.

Add the regions as unimplemented so that the status-quo in terms of boot
is maintained.

3d81e8cf0c hw/misc: Move some arm-related files from specific_ss into softmmu_ss
The header target/arm/kvm-consts.h checks CONFIG_KVM which is marked as
poisoned in common code, so the files that include this header have to
be added to specific_ss and recompiled for each, qemu-system-arm and
qemu-system-aarch64. However, since the kvm headers are only optionally
used in kvm-constants.h for some sanity checks, we can additionally
check the NEED_CPU_H macro first to avoid the poisoned CONFIG_KVM macro,
so kvm-constants.h can also be used from "common" files (without the
sanity checks - which should be OK since they are still done from other
target-specific files instead). This way, and by adjusting some other
include statements in the related files here and there, we can move some
files from specific_ss into softmmu_ss, so that they only need to be
compiled once during the build process.

bf0c50d4aa monitor: expose monitor_puts to rest of code
This helps us construct strings elsewhere before echoing to the

  monitor_printf(mon, "%s", s->str);

It will be useful in following patches but for now convert all
existing plain "%s" printfs to use the _puts api.

55c57023b7 hw/misc/aspeed: Add PECI controller
This introduces a really basic PECI controller that responses to
commands by always setting the response code to success and then raising
an interrupt to indicate the command is done. This helps avoid getting
hit with constant errors if the driver continuously attempts to send a
command and keeps timing out.

The AST2400 and AST2500 only included registers up to 0x5C, not 0xFC.
They supported PECI 1.1, 2.0, and 3.0. The AST2600 and AST1030 support
PECI 4.0, which includes more read/write buffer registers from 0x80 to
0xFC to support 64-byte mode.

This patch doesn't attempt to handle that, or to create a different
version of the controller for the different generations, since it's only
implementing functionality that is common to all generations.

The basic sequence of events is that the firmware will read and write to
various registers and then trigger a command by setting the FIRE bit in
the command register (similar to the I2C controller).

Then the firmware waits for an interrupt from the PECI controller,
expecting the interrupt status register to be filled in with info on
what happened. If the command was transmitted and received successfully,
then response codes from the host CPU will be found in the data buffer
registers.

 1. Allocating and initiating accumulative hash digest write buffer
    with initial state.
    * Since QEMU crypto/hash api doesn't provide the API to set initial
      state of hash library, and the initial state is already set by
      crypto library (gcrypt/glib/...), so skip this step.
 2. Calculating accumulative hash digest.
    (a) When receiving the last accumulative data, software need to add
        padding message at the end of the accumulative data. Padding
        message described in specific of MD5, SHA-1, SHA224, SHA256,
        SHA512, SHA512/224, SHA512/256.
        * Since the crypto library (gcrypt/glib) already pad the
          padding message internally.

b21e238037 Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).

b793b4ef8c mos6522: implement edge-triggering for CA1/2 and CB1/2 control line IRQs
The mos6522 datasheet describes how the control lines IRQs are edge-triggered
according to the configuration in the PCR register. Implement the logic according
to the datasheet so that the interrupt bits in IFR are latched when the edge is
detected, and cleared when reading portA/portB or writing to IFR as necessary.

To maintain bisectibility this change also updates the SCSI, SCSI data, Nubus
and VIA2 60Hz/1Hz clocks in the q800 machine to be negative edge-triggered as
confirmed by the PCR programming in all of Linux, NetBSD and MacOS.

677a4725b1 mac_via: make SCSI_DATA (DRQ) bit live rather than latched
The VIA2 on the Q800 machine is not a separate chip as in older Macs but instead
is integrated into the on-board logic. From analysing the SCSI routines in the
MacOS toolbox ROM (and to a lesser extent NetBSD and Linux) the expectation seems
to be that the SCSI_DATA (DRQ) bit is live on the Q800 and not latched.

Fortunately we can use the recently introduced mos6522 last_irq_levels variable
which tracks the edge-triggered state to return the SCSI_DATA (DRQ) bit live to
the guest OS.

This displays detailed information about the device registers and timers to aid

Currently the QAPI generators for HumanReadableText don't work correctly if

now manually add a hmp_info_via() wrapper until direct support for per-device
HMP/QMP commands is implemented.

17e3134061 Remove unnecessary minimum_version_id_old fields
The migration code will not look at a VMStateDescription's
minimum_version_id_old field unless that VMSD has set the
load_state_old field to something non-NULL.  (The purpose of
minimum_version_id_old is to specify what migration version is needed
for the code in the function pointed to by load_state_old to be able
to handle it on incoming migration.)

We have exactly one VMSD which still has a load_state_old,
in the PPC CPU; every other VMSD which sets minimum_version_id_old
is doing so unnecessarily. Delete all the unnecessary ones.

Commit created with:
  sed -i '/\.minimum_version_id_old/d' $(git grep -l '\.minimum_version_id_old')
with the one legitimate use then hand-edited back in.

2f93d8b04a rtc: Move RTC function prototypes to their own header
softmmu/rtc.c defines two public functions: qemu_get_timedate() and
qemu_timedate_diff().  Currently we keep the prototypes for these in
qemu-common.h, but most files don't need them.  Move them to their
own header, a new include/sysemu/rtc.h.

Since the C files using these two functions did not need to include
qemu-common.h for any other reason, we can remove those include lines
when we add the include of the new rtc.h.

The license for the .h file follows that of the softmmu/rtc.c
where both the functions are defined.

119df56bf0 hw/misc/aspeed_i3c.c: Introduce a dummy AST2600 I3C model.
Aspeed 2600 SDK enables I3C support by default.  The I3C driver will try
to reset the device controller and set it up through device address table
register.  This dummy model responds to these registers with default values
as listed in the ast2600v10 datasheet chapter 54.2.

This avoids a guest machine kernel panic due to referencing an
invalid kernel address if the device address table register isn't
set correctly.

ef80a708b5 ivshmem.c: change endianness to LITTLE_ENDIAN
The ivshmem device, as with most PCI devices, uses little endian byte
order. However, the endianness of its mmio_ops is marked as
DEVICE_NATIVE_ENDIAN. This presents not only the usual problems with big
endian hosts but also with PowerPC little endian hosts as well, since
the Power architecture in QEMU uses big endian hardware (XIVE controller,
PCI Host Bridges, etc) even if the host is in little endian byte order.

As it is today, the IVPosition of the device will be byte swapped when
running in Power BE and LE. This can be seen by changing the existing
qtest 'ivshmem-test' to run in ppc64 hosts and printing the IVPOSITION
regs in test_ivshmem_server() right after the VM ids assert. For x86_64
the VM id values read are '0' and '1', for ppc64 (tested in a Power8
RHEL 7.9 BE server) and ppc64le (tested in a Power9 RHEL 8.6 LE server)
the ids will be '0' and '0x1000000'.

Change this device to LITTLE_ENDIAN fixes the issue for Power hosts of
both endianness, and every other big-endian architecture that might use
this device, without impacting x86 users.

64eaa82095 hw: Replace trivial drive_get_next() by drive_get()
drive_get_next() is basically a bad idea.  It returns the "next" block
backend of a certain interface type.  "Next" means bus=0,unit=N, where
subsequent calls count N up from zero, per interface type.

This lets you define unit numbers implicitly by execution order.  If the
order changes, or new calls appear "in the middle", unit numbers change.
ABI break.  Hard to spot in review.

A number of machines connect just one backend with drive_get_next().
Change them to use drive_get() directly.  This makes the (zero) unit
number explicit in the code.
