Avoid undefined behaviour from shifting left into the sign bit:
hw/ide/ahci.c:551:36: runtime error: left shift of 255 by 24 places cannot be represented in type 'int'

- Use a hash table indexed on bus pointers to store information about buses
instead of using the bus numbers.
Bus pointers are stored in a new VTDBus struct together with the vector
of device address space pointers indexed by devfn.
- The bus number is still used for lookup for selective SID based invalidate,
in which case the bus number is lazily resolved from the bus hash table and
cached in a separate index.

A QEMU breakpoint match is not definitely an architectural breakpoint
match. If an exception is generated unconditionally during translation,
it is hardly possible to ignore it in the debug exception handler.

exception only if any breakpoint matches architecturally.

The --aio=MODE option enables Linux AIO or Windows overlapped I/O.
The #ifdef CONFIG_LINUX_AIO was a layering violation that also prevented
Windows overlapped I/O from being used.
Now that raw-posix.c prints an error when Linux AIO has not been
compiled in, we can unconditionally compile the option into qemu-nbd.
After this patch qemu-nbd --aio=native works on Windows.

raw-posix.c silently ignores BDRV_O_NATIVE_AIO if libaio is unavailable.
It is confusing when aio=native performance is identical to aio=threads
because the binary was accidentally built without libaio.
Print a deprecation warning if -drive aio=native is used with a binary
that does not support libaio. There are probably users using aio=native
who would be inconvenienced if QEMU suddenly refused to start their
guests. In the future this will become an error.

Multiple sub-systems in QEMU may find it useful to generate IDs
for objects that a user may reference via QMP or HMP. This patch
presents a standardized way to do it, so that automatic ID generation
follows the same rules.
This patch enforces the following rules when generating an ID:
1.) Guarantee no collisions with a user-specified ID
2.) Identify the sub-system the ID belongs to
3.) Guarantee of uniqueness
4.) Spoiling predictability, to avoid creating an assumption
of object ordering and parsing (i.e., we don't want users to think
they can guess the next ID based on prior behavior).
The scheme for this is as follows (no spaces):
# subsys D RR
Reserved char --| | | |
Subsystem String ----| | |
Unique number (64-bit) --| |
Two-digit random number ---|
For example, a generated node-name for the block sub-system may look
like this:
#block076
The caller of id_generate() is responsible for freeing the generated
node name string with g_free().

This cleans up the mess we left behind in the mirror code after the
previous patch. Instead of using bdrv_swap(), just change pointers.
The interface change of the mirror job that callers must consider is
that after job completion, their local BDS pointers still point to the
same node now. qemu-img must change its code accordingly (which makes it
easier to understand); the other callers stays unchanged because after
completion they don't do anything with the BDS, but just with the job,
and the job is still owned by the source BDS.

Some block jobs change the block device graph on completion. This means
that the device that owns the job and originally was addressed with its
device name may no longer be what the corresponding BlockBackend points
to.
Previously, the effects of bdrv_swap() ensured that the job was (at
least partially) transferred to the target image. Events that contain
the device name could still use bdrv_get_device_name(job->bs) and get
the same result.
After removing bdrv_swap(), this won't work any more. Instead, save the
device name at job creation and use that copy for QMP events and
anything else identifying the job.

Remember all parent nodes and just change the pointers there instead of
swapping the contents of the BlockDriverState.
Handling of snapshot=on must be moved further down in bdrv_open()
because *pbs (which is the bs pointer in the BlockBackend) must already
be set before bdrv_append() is called. Otherwise bdrv_append() changes
the BB's pointer to the temporary snapshot, but bdrv_open() overwrites
it with the read-only original image.
We also need to be careful to update callers as the interface changes
(becomes less insane): Previously, the meaning of the two parameters was
inverted when bdrv_append() returns. Now any BDS pointers keep pointing
to the same node.

After bdrv_swap(), some fields must be moved back to their original BDS
to compensate for the effects that a swap of the contents of the objects
has while keeping the old addresses. Other fields must be moved back
because they should logically be moved and must stay on top
When replacing bdrv_swap() with operations changing the pointers in the
parents, we only need the latter and must avoid swapping the former.

This is the final step in converting all of the BlockDriverState
pointers that block drivers use to BdrvChild.
After this patch, bs->children contains the full list of child nodes
that are referenced by a given BDS, and these children are only
referenced through BdrvChild, so that updating the pointer in there is
enough for changing edges in the graph.

dump will be produced if a program aborts. This is not necessarily the
case because core dumps can be disabled using ulimit.
Since we cannot guarantee that abort() will produce a core dump, we
should use SIGKILL instead (that does not produce any) and update the

ARM/AArch64 KVM guests don't have any way to identify
themselves as KVM guests (x86 guests use a CPUID leaf). Now, we
could discuss all sorts of reasons why guests shouldn't need to
know that, but then there's always some case where it'd be
nice... Anyway, now that we have SMBIOS tables in ARM guests,
it's easy for the guest to know that it's a QEMU instance. This
patch takes that one step further, also identifying KVM, when
appropriate. Again, we could debate why generally nothing
should care whether it's of type QEMU or QEMU/KVM, but again,
sometimes it's nice to know...
