377f8f08be gdbstub: Introduce gdb_get_float32() to get 32-bit float registers
Since we now use a GByteArray, we can not use stfl_p() directly.
Introduce the gdb_get_float32() helper to load a float32 register.

2e79802445 thread.h: Remove trailing semicolons from Coverity qemu_mutex_lock() etc
All the Coverity-specific definitions of qemu_mutex_lock() and friends
have a trailing semicolon. This works fine almost everywhere because
of QEMU's mandatory-braces coding style and because most callsites are
simple, but target/s390x/sigp.c has a use of qemu_mutex_trylock() as
an if() statement, which makes the ';' a syntax error:
"../target/s390x/sigp.c", line 461: warning #18: expected a ")"
      if (qemu_mutex_trylock(&qemu_sigp_mutex)) {
          ^

Remove the bogus semicolons from the macro definitions.

062c73c51e thread.h: Fix Coverity version of qemu_cond_timedwait()
For Coverity's benefit, we provide simpler versions of functions like
qemu_mutex_lock(), qemu_cond_wait() and qemu_cond_timedwait().  When
we added qemu_cond_timedwait() in commit 3dcc9c6ec4, a cut and
paste error meant that the Coverity version of qemu_cond_timedwait()
was using the wrong _impl function, which makes the Coverity parser
complain:

"/qemu/include/qemu/thread.h", line 159: warning #140: too many arguments in
          function call
      return qemu_cond_timedwait(cond, mutex, ms);
             ^

"/qemu/include/qemu/thread.h", line 159: warning #120: return value type does
          not match the function type
      return qemu_cond_timedwait(cond, mutex, ms);

  static inline bool (qemu_cond_timedwait)(QemuCond *cond, QemuMutex *mutex,
                      ^

These aren't fatal, but reduce the scope of the analysis. Fix the error.

In commit a1a98357e3 in 2018 we added some workarounds for Coverity
not being able to handle the _Float* types introduced by recent
glibc.  Newer versions of the Coverity scan tools have support for
these types, and will fail with errors about duplicate typedefs if we
have our workaround.  Remove our copy of the typedefs.

394f0f72fd fw_cfg: Migrate ACPI table mr sizes separately
Any sub-page size update to ACPI MRs will be lost during
migration, as we use aligned size in ram_load_precopy() ->
qemu_ram_resize() path. This will result in inconsistency in
FWCfgEntry sizes between source and destination. In order to avoid
this, save and restore them separately during migration.

Up until now, this problem may not be that relevant for x86 as both
ACPI table and Linker MRs gets padded and aligned. Also at present,
qemu_ram_resize() doesn't invoke callback to update FWCfgEntry for
unaligned size changes. But since we are going to fix the
qemu_ram_resize() in the subsequent patch, the issue may become
more serious especially for RSDP MR case.

Moreover, the issue will soon become prominent in arm/virt as well
where the MRs are not padded or aligned at all and eventually have
acpi table changes as part of future additions like NVDIMM hot-add
feature.

d489ae4ac5 memory: Do not allow direct write access to rom_device regions
According to the documentation in memory.h a ROM memory region will be
backed by RAM for reads, but is supposed to go through a callback for
writes. Currently we were not checking for the existence of the rom_device
flag when determining if we could perform a direct write or not.

To correct that add a check to memory_region_is_direct so that if the
memory region has the rom_device flag set we will return false for all
checks where is_write is set.

3c18a92dc4 aio-wait: delegate polling of main AioContext if BQL not held
Any thread that is not a iothread returns NULL for qemu_get_current_aio_context().
As a result, it would also return true for
in_aio_context_home_thread(qemu_get_aio_context()), causing
AIO_WAIT_WHILE to invoke aio_poll() directly.  This is incorrect
if the BQL is not held, because aio_poll() does not expect to
run concurrently from multiple threads, and it can actually
happen when savevm writes to the vmstate file from the
migration thread.

Therefore, restrict in_aio_context_home_thread to return true
for the main AioContext only if the BQL is held.

The function is moved to aio-wait.h because it is mostly used
there and to avoid a circular reference between main-loop.h
and block/aio.h.

01ef6b9e4e linux-user: factor out reading of /proc/self/maps
Unfortunately reading /proc/self/maps is still considered the gold
standard for a process finding out about it's own memory layout. As we
will want this data in other contexts soon factor out the code to read
and parse the data. Rather than just blindly copying the existing
sscanf based code we use a more modern glib version of the parsing
code to make a more general purpose map structure.

fbb92b6798 block: Increase BB.in_flight for coroutine and sync interfaces
External callers of blk_co_*() and of the synchronous blk_*() functions
don't currently increase the BlockBackend.in_flight counter, but calls
from blk_aio_*() do, so there is an inconsistency whether the counter
has been increased or not.

This patch moves the actual operations to static functions that can
later know they will always be called with in_flight increased exactly
once, even for external callers using the blk_co_*() coroutine
interfaces.

If the public blk_co_*() interface is unused, remove it.

25f3170b06 ppc/pnv: Create BMC devices only when defaults are enabled
Commit e2392d4395 ("ppc/pnv: Create BMC devices at machine init")
introduced default BMC devices which can be a problem when the same
devices are defined on the command line with :

  -device ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10

QEMU fails with :

  qemu-system-ppc64: error creating device tree: node: FDT_ERR_EXISTS

Use defaults_enabled() when creating the default BMC devices to let
the user provide its own BMC devices using '-nodefaults'. If no BMC
device are provided, output a warning but let QEMU run as this is a
supported configuration. However, when multiple BMC devices are
defined, stop QEMU with a clear error as the results are unexpected.

5c30ef937f vl/s390x: fixup ram sizes for compat machines
Older QEMU versions did fixup the ram size to match what can be reported
via sclp. We need to mimic this behaviour for machine types 4.2 and
older to not fail on inbound migration for memory sizes that do not fit.
Old machines with proper aligned memory sizes are not affected.

Alignment table:
 VM size (<=) | Alignment
--------------------------
      1020M   |     1M
      2040M   |     2M
      4080M   |     4M
      8160M   |     8M
     16320M   |    16M
     32640M   |    32M
     65280M   |    64M
    130560M   |   128M
    261120M   |   256M
    522240M   |   512M
   1044480M   |     1G
   2088960M   |     2G
   4177920M   |     4G
   8355840M   |     8G

Suggested action is to replace unaligned -m value with a suitable
aligned one or if a change to a newer machine type is possible, use a
machine version >= 5.0.

A future version might remove the compatibility handling.

For machine types >= 5.0 we can simply use an increment size of 1M and
use the full range of increment number which allows for all possible
memory sizes. The old limitation of having a maximum of 1020 increments
was added for standby memory, which we no longer support. With that we
can now support even weird memory sizes like 10001234 MB.

As we no longer fixup maxram_size as well, make other users use ram_size
instead. Keep using maxram_size when setting the maximum ram size in KVM,
as that will come in handy in the future when supporting memory hotplug
(in contrast, storage keys and storage attributes for hotplugged memory
will have to be migrated per RAM block in the future).

7568b20555 hw/386: Add EPYC mode topology decoding functions
These functions add support for building EPYC mode topology given the smp
details like numa nodes, cores, threads and sockets.

The new apic id decoding is mostly similar to current apic id decoding
except that it adds a new field node_id when numa configured. Removes all
the hardcoded values. Subsequent patches will use these functions to build
the topology.

Following functions are added.
apicid_llc_width_epyc
apicid_llc_offset_epyc
apicid_pkg_offset_epyc
apicid_from_topo_ids_epyc
x86_topo_ids_from_idx_epyc
x86_topo_ids_from_apicid_epyc
x86_apicid_from_cpu_idx_epyc

The topology details are available in Processor Programming Reference (PPR)
for AMD Family 17h Model 01h, Revision B1 Processors. The revision guides are
available from the bugzilla Link below.

9e58f17270 fdc/i8257: implement verify transfer mode
While working on the Tulip driver i tried to write some Teledisk images to
a floppy image which didn't work. Turned out that Teledisk checks the written
data by issuing a READ command to the FDC but running the DMA controller
in VERIFY mode. As we ignored the DMA request in that case, the DMA transfer
never finished, and Teledisk reported an error.

The i8257 spec says about verify transfers:

3) DMA verify, which does not actually involve the transfer of data. When an
8257 channel is in the DMA verify mode, it will respond the same as described
for transfer operations, except that no memory or I/O read/write control signals
will be generated.

Hervé proposed to remove all the dma_mode_ok stuff from fdc to have a more
clear boundary between DMA and FDC, so this patch also does that.

5a5e7f8cd8 block: trickle down the fallback image creation function use to the block drivers
Instead of checking the .bdrv_co_create_opts to see if we need the
fallback, just implement the .bdrv_co_create_opts in the drivers that
need it.

This way we don't break various places that need to know if the
underlying protocol/format really supports image creation, and this way
we still allow some drivers to not support image creation.

Fixes: fd17146cd9
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1816007

Note that technically this driver reverts the image creation fallback
for the vxhs driver since I don't have a means to test it, and IMHO it
is better to leave it not supported as it was prior to generic image
creation patches.

Also drop iscsi_create_opts which was left accidentally.

299ea9ff01 block/dirty-bitmap: improve _next_dirty_area API
Firstly, _next_dirty_area is for scenarios when we may contiguously
search for next dirty area inside some limited region, so it is more
comfortable to specify "end" which should not be recalculated on each
iteration.

Secondly, let's add a possibility to limit resulting area size, not
limiting searching area. This will be used in NBD code in further
commit. (Note that now bdrv_dirty_bitmap_next_dirty_area is unused)

9399c54b75 block/dirty-bitmap: add _next_dirty API
We have bdrv_dirty_bitmap_next_zero, let's add corresponding
bdrv_dirty_bitmap_next_dirty, which is more comfortable to use than
bitmap iterators in some cases.

For test modify test_hbitmap_next_zero_check_range to check both
next_zero and next_dirty and add some new checks.

642700fda0 block/dirty-bitmap: switch _next_dirty_area and _next_zero to int64_t
We are going to introduce bdrv_dirty_bitmap_next_dirty so that same
variable may be used to store its return value and to be its parameter,
so it would int64_t.

Similarly, we are going to refactor hbitmap_next_dirty_area to use
hbitmap_next_dirty together with hbitmap_next_zero, therefore we want
hbitmap_next_zero parameter type to be int64_t too.

So, for convenience update all parameters of *_next_zero and
*_next_dirty_area to be int64_t.

The function is definitely internal (it's not used by third party and
it has complicated interface). Move it to .c file.
