hw/arm/imx8mp-evk: Fix guest time in KVM mode
The imx8mp DTB hardcodes the clock frequency of the system counter to 8MHz.
In KVM mode, the host CPU is used whose system counter runs at a different
frequency, resulting in the guest clock running slower or faster. Fix this
by not hardcoding the clock frequency which makes the Linux driver read
the real clock frequency from the register.

migration/savevm: Add a compatibility check for capabilities
It has always been possible to enable arbitrary migration capabilities
and attempt to take a snapshot of the VM with the savevm/loadvm
commands as well as their QMP counterparts
snapshot-save/snapshot-load.
Most migration capabilities are not meant to be used with snapshots
and there's a risk of crashing QEMU or producing incorrect
behavior. Ideally, every migration capability would either be
implemented for savevm or explicitly rejected.
Add a compatibility check routine and reject the snapshot command if
an incompatible capability is enabled. For now only act on the the two
that actually cause a crash: multifd and mapped-ram.

ram-block-attributes: fix interaction with hugetlb memory backends
Currently, CoCo VMs can perform conversion at the base page granularity,
which is the granularity that has to be tracked. In relevant setups, the
target page size is assumed to be equal to the host page size, thus
fixing the block size to the host page size.
However, since private memory and shared memory have different backend
at present, users can specify shared memory with a hugetlbfs backend
while private memory with guest_memfd backend only supports 4K page
size. In this scenario, ram_block->page_size is different from the host
page size which will trigger an assertion when retrieving the block
size.
To address this, return the host page size directly to relax the
restriction. This changes fixes a regression of using hugetlbfs backend
for shared memory within CoCo VMs, with or without VFIO devices' presence.

migration: Fix regression of passing error_fatal into vmstate_load_state()
error_fatal is passed to vmstate_load_state() and vmstate_save_state()
functions. This was introduced in commit c632ffbd74. This would exit(1)
on error, and therefore does not allow to propagate the error back to
the caller.
To maintain consistency with prior error handling i.e. either propagating
the error to the caller or reporting it, we must set the error within a
local Error object instead of using error_fatal.

To fix that, we also have to convert several other functions to
set errp instead of error_reporting.

The handlers .pre_load_errp, .post_load_errp and .pre_save_errp
should put all needed information into errp, we should not append
error number here.
Note, that there are some more error messages with numeric
error codes in this file. We leave them for another day, our
current goal is to prepare for the following commit, which will
update interface of _errp() APIs.

migration: vmsd errp handlers: return bool
No code actually depend on specific errno values returned by
vmstate_load_state. The only use of it is to check for success,
and sometimes inject numeric error values into error messages
in migration code. The latter is not a stopper for gradual
conversion to "errp + bool return value" APIs.
Big analysis of vmstate_load_state() callers, showing that
specific errno values are not actually used, is done by Peter
here:
https://lore.kernel.org/qemu-devel/[email protected]/
Converting of vmstate_load_state() itself will follow in
another series.

system/physmem: mark io_mem_unassigned lockless
When the Bus Master bit is disabled in a PCI device's Command Register,
the device's DMA address space becomes unassigned memory (i.e. the
io_mem_unassigned MemoryRegion).
This can lead to deadlocks with IOThreads since io_mem_unassigned
accesses attempt to acquire the Big QEMU Lock (BQL). For example,
virtio-pci devices deadlock in virtio_write_config() ->
virtio_pci_stop_ioeventfd() when waiting for the IOThread while holding
the BQL. The IOThread is unable to acquire the BQL but the vcpu thread
won't release the BQL while waiting for the IOThread.
io_mem_unassigned is trivially thread-safe since it has no state, it
simply rejects all load/store accesses. Therefore it is safe to enable
lockless I/O on io_mem_unassigned to eliminate this deadlock.
Here is the backtrace described above:

crash the block layer later with something like:
Meanwhile, src QEMU cannot try to continue either even if dest QEMU can
release the drive locks (e.g. by QMP "stop"). Because as long as dest QEMU

cleanup of all incoming postcopy resources, postcopy-ram and postcopy

Furthermore, this patch also renames the postcopy_ram_listen_thread to
postcopy_listen_thread, as this thread handles not only postcopy-ram,
but also dirty-bitmaps and in the future it could handle other
postcopiable devices.

migration: Refactor all incoming cleanup info migration_incoming_destroy()
Currently, there are two functions that are responsible for calling the
cleanup of the incoming migration state. With successful precopy, it's
the incoming migration coroutine, and with successful postcopy it's the
postcopy listen thread. However, if postcopy fails during in the device
load, both functions will try to do the cleanup.
This patch refactors all cleanup that needs to be done on the incoming
side into a common function and defines a clear boundary, who is
responsible for the cleanup. The incoming migration coroutine is
responsible for calling the cleanup function, unless the listen thread
has been started, in which case the postcopy listen thread runs the
incoming migration cleanup in its BH.

migration: Introduce POSTCOPY_DEVICE state
Currently, when postcopy starts, the source VM starts switchover and
sends a package containing the state of all non-postcopiable devices.
When the destination loads this package, the switchover is complete and
the destination VM starts. However, if the device state load fails or
the destination side crashes, the source side is already in
POSTCOPY_ACTIVE state and cannot be recovered, even when it has the most
up-to-date machine state as the destination has not yet started.
This patch introduces a new POSTCOPY_DEVICE state which is active while
the destination machine is loading the device state, is not yet running,
and the source side can be resumed in case of a migration failure.
Return-path is required for this state to function, otherwise it will be
skipped in favor of POSTCOPY_ACTIVE.
To transition from POSTCOPY_DEVICE to POSTCOPY_ACTIVE, the source
side uses a PONG message that is a response to a PING message processed
just before the POSTCOPY_RUN command that starts the destination VM.
Thus, this feature is effective even if the destination side does not
yet support this new state.
