spapr_reallocate_hpt() has three users, two of which pass &error_fatal
and the third one, htab_load(), passes &local_err, uses it to detect
failures and simply propagates -EINVAL up to vmstate_load(), which will
cause QEMU to exit. It is thus confusing that spapr_reallocate_hpt()
doesn't return right away when an error is detected in some cases. Also,
the comment suggesting that the caller is welcome to try to carry on
seems like a remnant in this respect.
This can be improved:
- change spapr_reallocate_hpt() to always report a negative errno on
failure, either as reported by KVM or -ENOSPC if the HPT is smaller
than what was asked,
- use that to detect failures in htab_load() which is preferred over
checking &local_err,
- propagate this negative errno to vmstate_load() because it is more
accurate than propagating -EINVAL for all possible errors.

If kvmppc_load_htab_chunk() fails, its return value is propagated up
to vmstate_load(). It should thus be a negative errno, not -1 (which
maps to EPERM and would lure the user into thinking that the problem
is necessarily related to a lack of privilege).
Return the error reported by KVM or ENOSPC in case of short write.
While here, propagate the error message through an @errp argument
and have the caller to print it with error_report_err() instead
of relying on fprintf().

As recommended in "qapi/error.h", add a bool return value to
spapr_add_lmbs() and spapr_add_nvdimm(), and use them instead
of local_err in spapr_memory_plug().
This allows to get rid of the error propagation overhead.

Both PC_DIMM_SLOT_PROP and PC_DIMM_ADDR_PROP are defined in the
default property list of the PC DIMM device class:
DEFINE_PROP_UINT64(PC_DIMM_ADDR_PROP, PCDIMMDevice, addr, 0),
DEFINE_PROP_INT32(PC_DIMM_SLOT_PROP, PCDIMMDevice, slot,
PC_DIMM_UNASSIGNED_SLOT),
They should thus be always gettable for both PC DIMMs and NVDIMMs.
An error in getting them can only be the result of a programming
error. It doesn't make much sense to propagate the error in this
case. Abort instead.

Use object_property_get_int() instead of object_property_get_uint().
Since spapr_memory_plug() only gets called if pc_dimm_pre_plug()
succeeded, we expect to have a valid >= 0 slot number, either because
the user passed a valid slot number or because pc_dimm_get_free_slot()
picked one up for us.

Now that the error path of spapr_cpu_core_realize() is just to call

spapr_cpu_core_realize() has a rollback path which partially duplicates
the code of spapr_cpu_core_unrealize().
Let's make spapr_cpu_core_unrealize() idempotent and call it instead. This
requires to:
- move the registration and unregistration of the reset handler around
but it is harmless,
- allocate the array of vCPUs with g_new0() to be able to filter out
unused slots,
- make sure to only unrealize vCPUs that have been already realized.

Since we introduced CPU hot-unplug in sPAPR, we don't unrealize the
vCPU objects explicitly. Instead, we let QOM handle that for us under
object_property_del_all() when the CPU core object is finalized. The
only thing we do is calling cpu_remove_sync() to tear the vCPU thread
down.
This happens to work but it is ugly because:
- we call qdev_realize() but the corresponding qdev_unrealize() is
buried deep in the QOM code
- we call cpu_remove_sync() to undo qemu_init_vcpu() called by
ppc_cpu_realize() in target/ppc/translate_init.c.inc
- the CPU init and teardown paths aren't really symmetrical
The latter didn't bite us so far but a future patch that greatly
simplifies the CPU core realize path needs it to avoid a crash
in QOM.
For all these reasons, have ppc_cpu_unrealize() to undo the changes
of ppc_cpu_realize() by calling cpu_remove_sync() at the right place,
and have the sPAPR CPU core code to call qdev_unrealize().
This requires to add a missing stub because translate_init.c.inc is
also compiled for user mode.

When a CPU core is being removed, the machine specific data of each
CPU thread object is leaked.
Fix this by calling the dedicated helper we have for that instead of
simply unparenting the CPU object. Call it from a separate loop in

The spapr_create_nvdimm_dr_connectors() function doesn't need to access
any internal details of the sPAPR NVDIMM implementation. Also, pretty
much like for the LMBs, only spapr_machine_init() is responsible for the
creation of DR connectors for NVDIMMs.

If we hotplug a CPU during the first second of the kernel boot,
the IRQ can be sent to the kernel while the RTAS event handler
is not installed. The event is queued, but the kernel doesn't
collect it and ignores the new CPU.
As the code relies on edge-triggered IRQ, we can re-assert it
during the event-scan RTAS call if there are still pending
events (as it is already done in check-exception).

The errors are very useful when debugging qtest failures, especially when
QTEST_LOG=1 is set. Let's allow override MigrateStart.hide_stderr when
QTEST_LOG=1 is specified, because that means the user wants to be verbose.
Not very nice to introduce the first QTEST_LOG env access in migration-test.c,
however it should be handy. Without this patch, I was hacking error_report()
when debugging such errors. Let's make things easier.

Logically below race could trigger with the old code:
test program migration thread
------------ ----------------
wait_until('postcopy-pause')
postcopy_pause()
set_state('postcopy-pause')
do_postcopy_recover()
arm s->to_dst_file with new fd
release s->to_dst_file [1]
Here [1] could have released the just-installed recoverying channel. Then the
migration could hang without really resuming.
Instead, it should be very safe to release the fd before setting the state into
'postcopy-pause', because there's no reason for any other thread to touch it
during 'postcopy-active'.
Dave reported a very rare postcopy recovery hang that the migration-test
program waited for the migration to complete in migrate_postcopy_complete().
We do suspect it's the same thing that we're gonna fix here. Hard to tell.
However since we've noticed this, fix this irrelevant of the hang report.

Maintain a list of faulted addresses on the destination host for which we're
waiting on. This is implemented using a GTree rather than a real list to make
sure even there're plenty of vCPUs/threads that are faulting, the lookup will
still be fast with O(log(N)) (because we'll do that after placing each page).
It should bring a slight overhead, but ideally that shouldn't be a big problem
simply because in most cases the requested page list will be short.
Actually we did similar things for postcopy blocktime measurements. This patch
didn't use that simply because:
(1) blocktime measurement is towards vcpu threads only, but here we need to
record all faulted addresses, including main thread and external
thread (like, DPDK via vhost-user).
(2) blocktime measurement will require UFFD_FEATURE_THREAD_ID, but here we
don't want to add that extra dependency on the kernel version since not
necessary. E.g., we don't need to know which thread faulted on which
page, we also don't care about multiple threads faulting on the same
page. But we only care about what addresses are faulted so waiting for a
page copying from src.
(3) blocktime measurement is not enabled by default. However we need this by
default especially for postcopy recover.
Another thing to mention is that this patch introduced a new mutex to serialize
the receivedmap and the page_requested tree, however that serialization does
not cover other procedures like UFFDIO_COPY.

Commit ef96e3ae9698d6 in January 2019 removed the last user of the
VMSTATE_FLOAT64* macros. These were used by targets which defined
their floating point register file as an array of 'float64'.
We used to try to maintain a stricter distinction between
'float64' (a type for holding an integer representing an IEEE float)
and 'uint64_t', including having a debug option for 'float64' being
a struct and supposedly mandatory macros for converting between
float64 and uint64_t. We no longer think that's a usefully
strong distinction to draw and we allow ourselves to freely
assume that float64 really is just a 64-bit integer type, so
for new targets we would simply recommend use of the uint64_t type
for a floating point register file. The float64 type remains
as a useful way of documenting in the type signature of helper
functions and the like that they expect to receive an IEEE float
from the TCG generated code rather than an arbitrary integer.
Since the VMSTATE_FLOAT64* macros have no remaining users and
we don't recommend new code uses them, delete them.

A default value is provided for the variable 'bitmap_name' to avoid
a compiler warning.
The compiler showed the warning:

sectors_per_chunk is a 64 bit integer, but the calculation is done in 32
bits, leading to an overflow for coarse bitmap granularities.
If that results in the value 0, it leads to a hang where no progress is
made but send_bitmap_bits is constantly called with nr_sectors being 0.

With upstream commit#ea1edcd7da1a "vl: relocate paths to data
directories", the data dir logic was unified between POSIX &
Win32. That patch moved to using 'get_relocated_path()', to
find the data dir. There is a latent bug in get_relocated_path
which can cause it to spin indefinitely, when the bind dir is
the same as the passed in dir (in this case, it was the data
dir).

With upstream commit#8a19980e3fc4, logic was introduced to only
allow WHPX build on x64. But, the logic checks for the cpu family
and not the cpu. On my fedora container build, the cpu family is
x86 and the cpu is x86_64. Fixing the build break by checking for
the cpu, instead of the cpu family.

Since installation is not part of Makefiles anymore, Make need not
know the directories anymore. Meson already knows them through
built-in options, do everything using them instead of the config_host
dictionary.
