744c72a837 cpu: Rename CPUClass vmsd -> legacy_vmsd
Quoting Peter Maydell [*]:

  There are two ways to handle migration for
  a CPU object:

  (1) like any other device, so it has a dc->vmsd that covers
  migration for the whole object. As usual for objects that are a
  subclass of a parent that has state, the first entry in the
  VMStateDescription field list is VMSTATE_CPU(), which migrates
  the cpu_common fields, followed by whatever the CPU's own migration
  fields are.

  (2) a backwards-compatible mechanism for CPUs that were
  originally migrated using manual "write fields to the migration
  stream structures". The on-the-wire migration format
  for those is based on the 'env' pointer (which isn't a QOM object),
  and the cpu_common part of the migration data is elsewhere.

  cpu_exec_realizefn() handles both possibilities:

  * for type 1, dc->vmsd is set and cc->vmsd is not,
    so cpu_exec_realizefn() does nothing, and the standard
    "register dc->vmsd for a device" code does everything needed

  * for type 2, dc->vmsd is NULL and so we register the
    vmstate_cpu_common directly to handle the cpu-common fields,
    and the cc->vmsd to handle the per-CPU stuff

  You can't change a CPU from one type to the other without breaking
  migration compatibility, which is why some guest architectures
  are stuck on the cc->vmsd form. New targets should use dc->vmsd.

To avoid new targets to start using type (2), rename cc->vmsd as
cc->legacy_vmsd. The correct field to implement is dc->vmsd (the
DeviceClass one).

See also commit b170fce3dd ("cpu: Register VMStateDescription
through CPUState") for historic background.

calling CPUClass internal virtio_is_big_endian() one.

Similarly to commit bf7663c4bd ("cpu: introduce

name to hint this handler shouldn't be called anywhere but from the
virtio code.

632a887350 qemu-config: load modules when instantiating option groups
Right now the SPICE module is special cased to be loaded when processing
of the -spice command line option.  However, the spice option group
can also be brought in via -readconfig, in which case the module is
not loaded.

Add a generic hook to load modules that provide a QemuOpts group,
and use it for the "spice" and "iscsi" groups.

b4420f198d KVM: Dirty ring support
KVM dirty ring is a new interface to pass over dirty bits from kernel to the
userspace.  Instead of using a bitmap for each memory region, the dirty ring
contains an array of dirtied GPAs to fetch (in the form of offset in slots).
For each vcpu there will be one dirty ring that binds to it.

kvm_dirty_ring_reap() is the major function to collect dirty rings.  It can be
called either by a standalone reaper thread that runs in the background,
collecting dirty pages for the whole VM.  It can also be called directly by any
thread that has BQL taken.

2c20b27eed KVM: Provide helper to sync dirty bitmap from slot to ramblock
kvm_physical_sync_dirty_bitmap() calculates the ramblock offset in an
awkward way from the MemoryRegionSection that passed in from the
caller.  The truth is for each KVMSlot the ramblock offset never
change for the lifecycle.  Cache the ramblock offset for each KVMSlot
into the structure when the KVMSlot is created.

With that, we can further simplify kvm_physical_sync_dirty_bitmap()
with a helper to sync KVMSlot dirty bitmap to the ramblock dirty
bitmap of a specific KVMSlot.

a2f77862ff KVM: Use a big lock to replace per-kml slots_lock
Per-kml slots_lock will bring some trouble if we want to take all slots_lock of
all the KMLs, especially when we're in a context that we could have taken some
of the KML slots_lock, then we even need to figure out what we've taken and
what we need to take.

Make this simple by merging all KML slots_lock into a single slots lock.

Per-kml slots_lock isn't anything that helpful anyway - so far only x86 has two
address spaces (so, two slots_locks).  All the rest archs will be having one
address space always, which means there's actually one slots_lock so it will be
the same as before.

b87eaa9b82 memory: Introduce log_sync_global() to memory listener
Some of the memory listener may want to do log synchronization without
being able to specify a range of memory to sync but always globally.
Such a memory listener should provide this new method instead of the
log_sync() method.

Obviously we can also achieve similar thing when we put the global
sync logic into a log_sync() handler. However that's not efficient
enough because otherwise memory_global_dirty_log_sync() may do the
global sync N times, where N is the number of flat ranges in the
address space.

Make this new method be exclusive to log_sync().

cbb5638877 hw/arm: Model TCMs in the SSE-300, not the AN547
The SSE-300 has an ITCM at 0x0000_0000 and a DTCM at 0x2000_0000.
Currently we model these in the AN547 board, but this is conceptually
wrong, because they are a part of the SSE-300 itself. Move the
modelling of the TCMs out of mps2-tz.c into sse300.c.

This has no guest-visible effects.

0a6f0c76a0 coroutine-sleep: introduce qemu_co_sleep
Allow using QemuCoSleep to sleep forever until woken by qemu_co_sleep_wake.
This makes the logic of qemu_co_sleep_ns_wakeable easy to understand.

In the future we will introduce an API that can work even if the
sleep and wake happen from different threads.  For now, initializing
w->to_wake after timer_mod is fine because the timer can only fire in
the same AioContext.

29a6ea24eb coroutine-sleep: replace QemuCoSleepState pointer with struct in the API
Right now, users of qemu_co_sleep_ns_wakeable are simply passing
a pointer to QemuCoSleepState by reference to the function.  But
QemuCoSleepState really is just a Coroutine*; making the
content of the struct public is just as efficient and lets us
skip the user_state_pointer indirection.

Since the usage is changed, take the occasion to rename the
struct to QemuCoSleep.

have been moved to spapr_softmmu.c with the functions they depend on. The
functions is_ram_address and push_sregs_to_kvm_pr are not static anymore
as functions on both spapr_hcall.c and spapr_softmmu.c depend on them.
The hypercalls h_resize_hpt_prepare and h_resize_hpt_commit have been

was moved to spapr_softmmu.c
