That simplifies possible combinations to consider, but mainly it makes
PCIHP AML be governed only by BSEL, which is property of PCIBus

it will generate AML calls to hpbr's PCNT, which doesn't exists
since it's hotplugged bridge. As result DSDT becomes malformed,
with consequences that hotplug might stop working at best or
crash guest OS at worst, when it attempts to call non existing
PCNT method or during OS guest reboot when parsing DSDT again.
IASL de-compiles malformed AML of above config DSDT as:

+ External (_SB_.PCI0.S18_.S19_.PCNT, MethodObj) // Warning: Unknown method, guessing 2 arguments

it should be possible to add PCNT call to a child bridge only

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.

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

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.

This test is failing in gtk-vnc on Darwin:
$ make check-qtest-aarch64
...
19/20 qemu:qtest+qtest-aarch64 / qtest-aarch64/vnc-display-test
ERROR **: 10:42:35.488: vnc-error: Unsupported auth type 17973672
While QEMU picks the sigaltstack coroutine backend, gtk-vnc uses
the ucontext coroutine backend, which might be broken on Darwin.
Disable this test (current problem being investigated in this thread:
https://lore.kernel.org/qemu-devel/Y8kw6X6keB5l53nl@redhat.com/).

If we don't specify any machine, an architecture default
might be picked. But some architectures don't provide any
default, such ARM:
$ make check-qtest-aarch64
...
19/20 qemu:qtest+qtest-aarch64 / qtest-aarch64/vnc-display-test
qemu-system-aarch64: No machine specified, and there is no default
Since we don't need any particular machine to run this VNC
test, use the 'none' machine.

The HAXM project has been retired (see https://github.com/intel/haxm#status),
so we should mark the code in QEMU as deprecated (and finally remove it
unless somebody else picks the project up again - which is quite unlikely
since there are now whpx and hvf on these operating systems, too).
