gitlab-ci.d/buildtest: Merge the --without-default-* jobs
Let's safe some CI minutes by merging these two jobs. We can now
also drop "--disable-capstone" since the capstone submodule has
been removed a while ago. We should rather test --disable-fdt now
to check a compilation without the "dtc" submodule (for this we
have to drop i386-softmmu from the target list unfortunately).
Additionally, the qtests with s390x and sh4 are not read for
"--without-default-devices" yet, so we can only test mips64 and
avr here now.

tests/qtest/display-vga-test: Add proper checks if a device is available
display-vga-test currently tries to guess the usable VGA devices
according to the target architecture that is used for the test.
This of course does not work if QEMU has been built with the
"--without-default-devices" configure switch. To fix this, use the
qtest_has_device() function for the decision instead. This way
we can also consolidate most of the test functions into one single
function (that takes a parameter with the device name now), except
for the multihead test that tries to instantiate two devices and
thus is a little bit different.

qapi, audio: Make introspection reflect build configuration more closely
Currently the -audiodev accepts any audiodev type regardless of what is
built in to QEMU. An error only occurs later at runtime when a sound
device tries to use the audio backend.
With this change QEMU will immediately reject -audiodev args that are
not compiled into the binary. The QMP schema will also be introspectable
to identify what is compiled in.
This also helps to avoid compiling code that is not required in the
binary. Note: When building the audiodevs as modules, the patch only
compiles out code for modules that we don't build at all.

qapi, audio: add query-audiodev command
Way back in QEMU 4.0, the -audiodev command line option was introduced
for configuring audio backends. This CLI option does not use QemuOpts
so it is not visible for introspection in 'query-command-line-options',
instead using the QAPI Audiodev type. Unfortunately there is also no
QMP command that uses the Audiodev type, so it is not introspectable
with 'query-qmp-schema' either.
This introduces a 'query-audiodev' command that simply reflects back
the list of configured -audiodev command line options. This alone is
maybe not very useful by itself, but it makes Audiodev introspectable
via 'query-qmp-schema', so that libvirt (and other upper layer tools)
can discover the available audiodevs.

This reverts commit
db8a3772e300c1a656331a92da0785d81667dc81.
Motivation : this is breaking vhost-user with DPDK as reported in [0].

Fail to update device iotlb
Received unexpected msg type. Expected 40 received 22
Received unexpected msg type. Expected 22 received 11

Fail to update device iotlb
Received unexpected msg type. Expected 11 received 22
vhost VQ 0 ring restore failed: -71: Protocol error (71)
unable to start vhost net: 71: falling back on userspace virtio
The failing sequence that leads to the first error is :
- QEMU sends a VHOST_USER_GET_STATUS (40) request to DPDK on the master
socket
- QEMU starts a nested event loop in order to wait for the
VHOST_USER_GET_STATUS response and to be able to process messages from
the slave channel
- DPDK sends a couple of legitimate IOTLB miss messages on the slave
channel
- QEMU processes each IOTLB request and sends VHOST_USER_IOTLB_MSG (22)
updates on the master socket
- QEMU assumes to receive a response for the latest VHOST_USER_IOTLB_MSG
but it gets the response for the VHOST_USER_GET_STATUS instead
The subsequent errors have the same root cause : the nested event loop
breaks the order by design. It lures QEMU to expect responses to the
latest message sent on the master socket to arrive first.
Since this was only needed for DAX enablement which is still not merged
upstream, just drop the code for now. A working solution will have to
be merged later on. Likely protect the master socket with a mutex
and service the slave channel with a separate thread, as discussed with
Maxime in the mail thread below.

tests/qtest/bios-tables-test: Make the test less verbose by default
We are facing the issues that our test logs in the gitlab CI are
too big (and thus cut off). The bios-tables-test is one of the few
qtests that prints many lines of output by default when running with
V=1, so it contributes to this problem. Almost all other qtests are
silent with V=1 and only print debug messages with V=2 and higher.
Thus let's change the bios-tables-test to behave more like the
other tests and only print the debug messages with V=2 (or higher).

Such clean up effectively drops dynamic _DSM methods on non-hotpluggable
slots (even though bus itself is hotpluggable), but in practice it
affects only built-in devices (ide controllers/various bridges) that don't
use acpi-index anyways so effectively it doesn't matter (NICs are hotpluggble).
Follow up series will add static _DSM for non-hotpluggble devices/buses
that will not depend on ACPI PCI hotplug at all, and potentially would
allows us to reuse non-hotplug path elsewhere (PBX/microvm/arm-virt),
including new support for acpi-index for non-hotpluggable devices.

pcihp: acpi: ignore coldplugged bridges when composing hotpluggable slots
coldplugged bridges are not unpluggable, so there is no need
to describe slots where they are plugged as hotpluggable. To
that effect we have a condition that marks slot as non-hotpluggable
if it's populated by coldplugged bridge and prevents generation
_SUN/_EJ0 objects for it. That leaves dynamic _DSM method on
such slot (which also depends on BSEL and pcihp hardware).
This _DSM method provides only dynamic acpi-index support so far,
which is not actually used/supported by linux kernel for bridges
and it's doubtful there will be need for it at all.
So it's rather pointless to generate acpi-index related AML
for bridges and we can simplify hotplug slots generator a bit
more by completely ignoring coldplugged bridges on hotplug path.
Another point in favor of dropping dynamic _DSM support, is
that we can replace it with static _DSM if necessary since
a slot with bridge can't change during VM runtime and without
any dependency on ACPI PCI hotplug at that.
Later I plan to implement bridge specific static _DSM
PCI Firmware Specification 3.2
4.6.5. _DSM for Ignoring PCI Boot Configurations
part of spec, to fix longstanding issue with fixed IO/MEM
resource assignment that often leads to hotplugged device
being in-operational within the guest due limited IO/MEM
windows programmed on bridge at boot time.
Expected change when coldplugged bridge is ignored by hotplug
code, should look like:
- Scope (S18)
- {
- Name (ASUN, 0x03)
- Method (_DSM, 4, Serialized) // _DSM: Device-Specific Method
- {
- Local0 = Package (0x02)

pcihp: acpi: decouple hotplug and generic slots description
Split build_append_pci_bus_devices() onto generic part that builds
AML descriptions only for populated slots which is applicable to
both hotplug disabled and enabled bridges. And a hotplug only
part that complements generic AML with hotplug depended bits
(that depend on BSEL), like _SUN/_EJ0 entries, dynamic _DSM.
Hotplug part, will generate full 'Device' descriptors for
non-populated slots (like it used to be) and complementary
'Scope' descriptors for populated slots that are hotplug capable.
i.e. something like this:
- ...
+ Name (BSEL, 0x03)
+ Scope (S00)

While generic build_append_pci_bus_devices() still calls hotplug part at
its end it doesn't really depend on any hotplug bits anymore and later
both could be completely separated when it's necessary.
Main benefit though is that both build_append_pci_bus_devices() and
build_append_pcihp_slots() become more readable and it makes easier
to modify them with less risk of affecting another part. Also it opens
possibility to re-use generic part elsewhere (microvm, arm/virt).

pci: acpihp: assign BSEL only to coldplugged bridges
ACPI PCI hotplug would broken after bridge hotplug and then migration
if hotplugged bridge were specified on target at command line.
Currently it's not possible since, 'hotplugged' property was made
read-only for some time now.
The issue would happen due to BSEL being assigned to all bridges
during 1st 'reset':
source seq:
1. start 'pc' machine => sets BSEL to 0 on pci.0 (host-bridge)
2. hotplug bridge, no bsel is assigned (so far is ok)
target seq:
1. start 'pc' machine with
-S -device pci-bridge,id=hp_br,hotplugged=on
BSEL gets assigned to as follows
hp_br: 0
pci.0: 1
as result hotplug requests with migrated AML generated on source
would be misdirected to 'hp_br' instead of intended pci.0
While it's not issue at the moment, it's based on implicit assumptions
* 'hotplugged' property is read-only
* 1st reset happens before QEMU drops into monitor mode
which lets add hotplugged on source bridges as hotplugged ones
(anything added at that stage counts as hotplugged
(yet another assumption))
All of it looks too fragile to me, so lets restrict BSEL only
to cold-plugged bridges explicitly.
Migration wise it shouldn't break anything since assignment order
stays the same:
* user can't specify 'hotplugged=on' on CLI
* user can't specify 'hotplugged=off' at monitor stage or later
on older QEMU versions where 'hotplugged' is RW, hotplug is broken
after migration anyways and we cannot do anything to fix that.

pcihp: piix4: do not call acpi_pcihp_reset() when ACPI PCI hotplug is disabled
piix4_pm_reset() is calling acpi_pcihp_reset() when ACPI PCI hotplug
is disabled, which leads to assigning BSEL properties to bridges on path
acpi_set_bsel()
...
if (qbus_is_hotpluggable(BUS(bus))) {
// above happens to be true by default (though it's SHPC hotplug handler)
// set BSEL
}
At the moment the issue is masked by the fact that we use not only BSEL,
to decide if we should generated hoplug AML but also pcihp_bridge_en knob.
However the later patches will drop dependency on pcihp_bridge_en,
and use only BSEL exclusively to decide if hotplug AML for slots should be built,
which exposes issue.
We should not ever call acpi_pcihp_reset() if ACPI PCI hotplug is disabled,
make it so.
PS:
* Q35 does the right thing (i.e. it calls acpi_pcihp_reset only when pcihp is enabled)
* the issue also makes acpi_pcihp_update() logic run on SHPC enabled bridges,
which seems to be harmless

When ACPI PCI hotplug for Q35 was introduced (6.1), it was implemented
by hiding HPC capability on PCIE slot. That however led to a number of
regressions and to fix it, it was decided to keep HPC cap exposed
in ACPI PCI hotplug case and force guest in ACPI PCI hotplug mode
by other means [1].
That reduced meaning of x-native-hotplug to a compat knob [2] for

x86: don't let decompressed kernel image clobber setup_data
The setup_data links are appended to the compressed kernel image. Since
the kernel image is typically loaded at 0x100000, setup_data lives at
`0x100000 + compressed_size`, which does not get relocated during the
kernel's boot process.
The kernel typically decompresses the image starting at address
0x1000000 (note: there's one more zero there than the compressed image
above). This usually is fine for most kernels.
However, if the compressed image is actually quite large, then
setup_data will live at a `0x100000 + compressed_size` that extends into
the decompressed zone at 0x1000000. In other words, if compressed_size
is larger than `0x1000000 - 0x100000`, then the decompression step will
clobber setup_data, resulting in crashes.
Visually, what happens now is that QEMU appends setup_data to the kernel
image:
kernel image setup_data
|--------------------------||----------------|
0x100000 0x100000+l1 0x100000+l1+l2
The problem is that this decompresses to 0x1000000 (one more zero). So
if l1 is > (0x1000000-0x100000), then this winds up looking like:
kernel image setup_data
|--------------------------||----------------|
0x100000 0x100000+l1 0x100000+l1+l2
d e c o m p r e s s e d k e r n e l
|-------------------------------------------------------------|
0x1000000 0x1000000+l3
The decompressed kernel seemingly overwriting the compressed kernel
image isn't a problem, because that gets relocated to a higher address
early on in the boot process, at the end of startup_64. setup_data,
however, stays in the same place, since those links are self referential
and nothing fixes them up. So the decompressed kernel clobbers it.
Fix this by appending setup_data to the cmdline blob rather than the
kernel image blob, which remains at a lower address that won't get
clobbered.
This could have been done by overwriting the initrd blob instead, but
that poses big difficulties, such as no longer being able to use memory
mapped files for initrd, hurting performance, and, more importantly, the
initrd address calculation is hard coded in qboot, and it always grows
down rather than up, which means lots of brittle semantics would have to
be changed around, incurring more complexity. In contrast, using cmdline
is simple and doesn't interfere with anything.
The microvm machine has a gross hack where it fiddles with fw_cfg data
after the fact. So this hack is updated to account for this appending,
by reserving some bytes.

python/machine: Fix AF_UNIX path too long on macOS
On macOS, private $TMPDIR's are the default. These $TMPDIR's are
generated from a user's unix UID and UUID [1], which can create a
relatively long path:
/var/folders/d7/rz20f6hd709c1ty8f6_6y_z40000gn/T/
QEMU's avocado tests create a temporary directory prefixed by
"avo_qemu_sock_", and create QMP sockets within _that_ as well.
The QMP socket is unnecessarily long, because a temporary directory
is created for every QEMUMachine object.
/avo_qemu_sock_uh3w_dgc/qemu-37331-
10bacf110-monitor.sock
The path limit for unix sockets on macOS is 104: [2]
/*
* [XSI] Definitions for UNIX IPC domain.
*/
struct sockaddr_un {
unsigned char sun_len; /* sockaddr len including null */
sa_family_t sun_family; /* [XSI] AF_UNIX */
char sun_path[104]; /* [XSI] path name (gag) */
};
This results in avocado tests failing on macOS because the QMP unix
socket can't be created, because the path is too long:
ERROR| Failed to establish connection: OSError: AF_UNIX path too long
This change resolves by reducing the size of the socket directory prefix
and the suffix on the QMP and console socket names.
The result is paths like this:

virtio-blk: simplify virtio_blk_dma_restart_cb()
virtio_blk_dma_restart_cb() is tricky because the BH must deal with
virtio_blk_data_plane_start()/virtio_blk_data_plane_stop() being called.
There are two issues with the code:
1. virtio_blk_realize() should use qdev_add_vm_change_state_handler()
instead of qemu_add_vm_change_state_handler(). This ensures the
ordering with virtio_init()'s vm change state handler that calls
virtio_blk_data_plane_start()/virtio_blk_data_plane_stop() is
well-defined. Then blk's AioContext is guaranteed to be up-to-date in
virtio_blk_dma_restart_cb() and it's no longer necessary to have a
special case for virtio_blk_data_plane_start().
2. Only blk_drain() waits for virtio_blk_dma_restart_cb()'s
blk_inc_in_flight() to be decremented. The bdrv_drain() family of
functions do not wait for BlockBackend's in_flight counter to reach
zero. virtio_blk_data_plane_stop() relies on blk_set_aio_context()'s
implicit drain, but that's a bdrv_drain() and not a blk_drain().
Note that virtio_blk_reset() already correctly relies on blk_drain().
If virtio_blk_data_plane_stop() switches to blk_drain() then we can
properly wait for pending virtio_blk_dma_restart_bh() calls.
Once these issues are taken care of the code becomes simpler. This
change is in preparation for multiple IOThreads in virtio-blk where we
need to clean up the multi-threading behavior.
I ran the reproducer from commit
49b44549ace7 ("virtio-blk: On restart,
process queued requests in the proper context") to check that there is
no regression.

util/aio: Defer disabling poll mode as long as possible
When we measure FIO read performance (cache=writethrough, bs=4k,
iodepth=64) in VMs, ~80K/s notifications (e.g., EPT_MISCONFIG) are observed
from guest to qemu.
It turns out those frequent notificatons are caused by interference from
worker threads. Worker threads queue bottom halves after completing IO
requests. Pending bottom halves may lead to either aio_compute_timeout()
zeros timeout and pass it to try_poll_mode() or run_poll_handlers() returns
no progress after noticing pending aio_notify() events. Both cause
run_poll_handlers() to call poll_set_started(false) to disable poll mode.
However, for both cases, as timeout is already zeroed, the event loop
(i.e., aio_poll()) just processes bottom halves and then starts the next
event loop iteration. So, disabling poll mode has no value but leads to
unnecessary notifications from guest.
To minimize unnecessary notifications from guest, defer disabling poll
mode to when the event loop is about to be blocked.
With this patch applied, FIO seq-read performance (bs=4k, iodepth=64,
cache=writethrough) in VMs increases from 330K/s to 413K/s IOPS.

target/arm: Look up ARMCPRegInfo at runtime
Do not encode the pointer as a constant in the opcode stream.
This pointer is specific to the cpu that first generated the
translation, which runs into problems with both hot-pluggable
cpus and user-only threads, as cpus are removed. It's also a
potential correctness issue in the theoretical case of a
slightly-heterogenous system, because if CPU 0 generates a
TB and then CPU 1 executes it, CPU 1 will end up using CPU 0's
hash table, which might have a wrong set of registers in it.
(All our current systems are either completely homogenous,
M-profile, or have CPUs sufficiently different that they
wouldn't be sharing TBs anyway because the differences would
show up in the TB flags, so the correctness issue is only
theoretical, not practical.)
Perform the lookup in either helper_access_check_cp_reg,
or a new helper_lookup_cp_reg.

target/arm: Reorg do_coproc_insn
Move the ri == NULL case to the top of the function and return.
This allows the else to be removed and the code unindented.
