- Define new types for ast2700ssp INTC and INTCIO
- Add register definitions for SSP INTC and INTCIO
- Implement write handlers for SSP INTC and INTCIO
- Register new types in aspeed_intc_register_types
The design of the SSP INTC and INTCIO controllers is similar to
AST2700, with the following differences:
- AST2700
Support GICINT128 to GICINT136 in INTC
The INTCIO GIC_192_201 has 10 output pins, mapped as follows:
Bit 0 -> GIC 192
Bit 1 -> GIC 193
Bit 2 -> GIC 194
Bit 3 -> GIC 195
Bit 4 -> GIC 196
- AST2700-ssp
Support SSPINT128 to SSPINT136 in INTC
The INTCIO SSPINT_160_169 has 10 output pins, mapped as follows:
Bit 0 -> SSPINT 160
Bit 1 -> SSPINT 161
Bit 2 -> SSPINT 162
Bit 3 -> SSPINT 163
Bit 4 -> SSPINT 164

shutdown), this may lead to SEGFAULT on aio_co_wake(NULL).
As mentioned in the comment inside monitor_cleanup(), the intention is to
allow incoming requests while shutting down, but simply leave them
without any response. Let's do exactly that, and if qmp_dispatcher_co
coroutine pointer has already been set to NULL, let's simply skip the

Based on commit 1433e38cc8 ("hpet: do not overwrite properties on
post_load"), add the basic migration support to Rust HPET.
The current migration implementation introduces multiple unsafe
callbacks. Before the vmstate builder, one possible cleanup approach is
to wrap callbacks in the vmstate binding using a method similar to the
vmstate_exist_fn macro.
However, this approach would also create a lot of repetitive code (since
vmstate has so many callbacks: pre_load, post_load, pre_save, post_save,
needed and dev_unplug_pending). Although it would be cleaner, it would
somewhat deviate from the path of the vmstate builder.
Therefore, firstly focus on completing the functionality of HPET, and
those current unsafe callbacks can at least clearly indicate the needed
functionality of vmstate. The next step is to consider refactoring
vmstate to move towards the vmstate builder direction.
Additionally, update rust.rst about Rust HPET can support migration.

Currently, if the `num` field of a varray is not a numeric type, such as
being placed in a wrapper, the array variant of assert_field_type will
fail the check.
HPET currently wraps num_timers in BqlCell<>. Although BqlCell<> is not
necessary from strictly speaking, it makes sense for vmstate to respect
BqlCell.
The failure of assert_field_type is because it cannot convert BqlCell<T>
into usize for use as the index. Use a constant 0 instead for the index,
by avoiding $(...)? and extracting the common parts of
assert_field_type! into an internal case.

Unfortunately, at present it's not possible to have a const
"with_exist_check" method to append test_fn after vmstate_struct (due
to error on "constant functions cannot evaluate destructors" for `F`).
Before the vmstate builder, the only way to support "test_fn" is to
extend vmstate_struct macro to add the such new optional member (and
fortunately, Rust can still parse the current expansion!).
Abstract the previous callback implementation of vmstate_validate into
a separate macro, and moves it before vmstate_struct for vmstate_struct
to call.
Note that there's no need to add any extra flag for a new test_fn added
in the VMStateField.

[peterx: some cosmetic changes]
Signed-off-by: Peter Xu <peterx@redhat.com>
The preempt mode postcopy has been introduced for a while. From latency
POV, it should always win the vanilla postcopy.
However there's one thing missing when preempt mode is enabled right now,
which is the spatial locality hint when there're page requests from the
destination side.
In vanilla postcopy, as long as a page request was unqueued, it will update
the PSS of the precopy background stream, so that after a page request the
background thread will move the pages after whatever was requested. It's
pretty much a natural behavior when there's only one channel anyway, and
one scanner to send the pages.
Preempt mode didn't follow that, because preempt mode has its own channel
and its own PSS (which doesn't linearly scan the guest memory, but
dedicated to resolve page requested from destination). So the page request
process and the background migration process are completely separate.
This patch adds the hint explicitly for preempt mode. With that, whenever
the preempt mode receives a page request on the source, it will service the
remote page fault in the return path, then it'll provide a hint to the
background thread so that we'll start sending the pages right after the
requested ones in the background, assuming the follow up pages have a
higher chance to be accessed later.
NOTE: since the background migration thread and return path thread run
completely concurrently, it doesn't always mean the hint will be applied
every single time. For example, it's possible that the return path thread
receives multiple page requests in a row without the background thread
getting the chance to consume one. In such case, the preempt thread only
provide the hint if the previous hint has been consumed. After all,
there's no point queuing hints when we only have one linear scanner.
This could measureably improve the simple sequential memory access pattern
during postcopy (when preempt is on). For random accesses, I can measure a
slight increase of remote page fault latency from ~500us -> ~600us, that
could be a trade-off to have such hint mechanism, and after all that's
still greatly improved comparing to vanilla postcopy on random (~10ms).
The patch is verified by our QE team in a video streaming test case, to
reduce the pause of the video from ~1min to a few seconds when switching
over to postcopy with preempt mode.

Add a savevm handler for a module to opt-in sending extra sections right
before postcopy starts, and before VM is stopped.
RAM will start to use this new savevm handler in the next patch to do flush
and sync for multifd pages.
Note that we choose to do it before VM stopped because the current only
potential user is not sensitive to VM status, so doing it before VM is
stopped is preferred to enlarge any postcopy downtime.
It is still a bit unfortunate that we need to introduce such a new savevm
handler just for the only use case, however it's so far the cleanest.

The various logical migration channels don't have a
standardized way of advertising themselves and their
connections may be seen out of order by the migration
destination. When a new connection arrives, the incoming
migration currently make use of heuristics to determine
which channel it belongs to.
The next few patches will need to change how the multifd
and postcopy capabilities interact and that affects the
channel discovery heuristic.
Refactor the channel discovery heuristic to make it less
opaque and simplify the subsequent patches.

control_save_page() is for RDMA only, unfold it to make the code more
clear.
In addition:
- Similar to other branches style in ram_save_target_page(), involve RDMA
only if the condition 'migrate_rdma()' is true.
- Further simplify the code by removing the RAM_SAVE_CONTROL_NOT_SUPP.

Since we have disabled RDMA + postcopy, it's safe to remove
the migration_in_postcopy() that follows the migrate_rdma().

It's believed that RDMA + postcopy-ram has been broken for a while.
Rather than spending time re-enabling it, let's simply disable it as a
trade-off.

Depending on the order of starting RDMA and setting capability,
they can be categorized into the following scenarios:
Source:
S1: [set capabilities] -> [Start RDMA outgoing]
Destination:
D1: [set capabilities] -> [Start RDMA incoming]
D2: [Start RDMA incoming] -> [set capabilities]
Previously, compatibility between RDMA and capabilities was verified only
in scenario D1, potentially causing migration failures in other situations.
For scenarios S1 and D1, we can seamlessly incorporate
migration_transport_compatible() to address compatibility between
channels and capabilities vs transport.
For scenario D2, ensure compatibility within migrate_caps_check().

mc146818rtc's migration stream is at version 3 since commit
56038ef623 ("RTC: Update the RTC clock only when reading it")
from 12 years ago, released in QEMU v1.3.0!
No versioned machines are that old, we can safely remove
support for older streams and the qdev_set_legacy_instance_id()
call.

The test_ppc64_linux_smt_boot function lacks the set_machine('pseries'),
so this test is currently failing in case the 'pseries' machine has not
been compiled into the binary. Add the check now to fix it.

Python 3.8 went "end of life" in October 2024 and Fedora 42 dropped
this version already, so the "python" CI job is currently failing.
Thus it's time to drop support for this Python version in QEMU, too.
While we're at it, also look for "python3.13" in the configure script.
