a86d86ac0a acpi: arm/virt: build_spcr: use acpi_table_begin()/acpi_table_end() instead of build_header()
it replaces error-prone pointer arithmetic for build_header() API,
with 2 calls to start and finish table creation,
which hides offsets magic from API user.

while at it, replace packed structure with endian agnostic
build_append_FOO() API.

PS:
Spec is Microsoft hosted, however 1.02 is no where to be found
(MS lists only the current revision) and the current revision is 1.07,
so bring comments in line with 1.07 as this is the only available spec.
There is no content change between originally implemented 1.02
(using QEMU code as reference) and 1.07. The only change is renaming
'Reserved2' field to 'Language', with the same 0 value.

88b1045ead acpi: arm/virt: build_spcr: fix invalid cast
implicit cast to structure uint8_t member didn't raise error when
assigning value from incorrect enum, but when using build_append_gas()
(next patch) it will error out with (clang):
  implicit conversion from enumeration type 'AmlRegionSpace'
  to different enumeration type 'AmlAddressSpace'
fix cast error by using correct AML_AS_SYSTEM_MEMORY enum

patching it to enabled for hotpluggbale CPUs in DSDT,
set it to enabled at the time _MAT entry is built.

c151fd8710 acpi: add helper routines to initialize ACPI tables
Patch introduces acpi_table_begin()/ acpi_table_end() API
that hides pointer/offset arithmetic from user as opposed
to build_header(), to prevent errors caused by it [1].

 acpi_table_begin():
     initializes table header and keeps track of
     table data/offsets
 acpi_table_end():
     sets actual table length and tells bios loader
     where table is for the later initialization on
     guest side.

46ce017167 vhost-vsock: handle common features in vhost-vsock-common
virtio-vsock features, like VIRTIO_VSOCK_F_SEQPACKET, can be handled
by vhost-vsock-common parent class. In this way, we can reuse the
same code for all virtio-vsock backends (i.e. vhost-vsock,
vhost-user-vsock).

Let's move `seqpacket` property to vhost-vsock-common class, add
vhost_vsock_common_get_features() used by children, and disable
`seqpacket` for vhost-user-vsock device for machine types < 6.2.

The behavior of vhost-vsock device doesn't change; vhost-user-vsock
device now supports `seqpacket` property.

d6a9378f47 vhost-vsock: fix migration issue when seqpacket is supported
Commit 1e08fd0a46 ("vhost-vsock: SOCK_SEQPACKET feature bit support")
enabled the SEQPACKET feature bit.
This commit is released with QEMU 6.1, so if we try to migrate a VM where
the host kernel supports SEQPACKET but machine type version is less than
6.1, we get the following errors:

    Features 0x130000002 unsupported. Allowed features: 0x179000000
    Failed to load virtio-vhost_vsock:virtio
    error while loading state for instance 0x0 of device '0000:00:05.0/virtio-vhost_vsock'
    load of migration failed: Operation not permitted

Let's disable the feature bit for machine types < 6.1.
We add a new OnOffAuto property for this, called `seqpacket`.
When it is `auto` (default), QEMU behaves as before, trying to enable the
feature, when it is `on` QEMU will fail if the backend (vhost-vsock
kernel module) doesn't support it.

Fixes: 1e08fd0a46 ("vhost-vsock: SOCK_SEQPACKET feature bit support")

8fc898ce0b block/backup: avoid integer overflow of max-workers
QAPI generates `struct BackupPerf` where `max-workers` value is stored
in an `int64_t` variable.
But block_copy_async(), and the underlying code, uses an `int` parameter.

At the end that variable is used to initialize `max_busy_tasks` in
block/aio_task.c causing the following assertion failure if a value
greater than INT_MAX(2147483647) is used:

  ../block/aio_task.c:63: aio_task_pool_wait_one: Assertion `pool->busy_tasks > 0' failed.

Let's check that `max-workers` doesn't exceed INT_MAX and print an
error in that case.

654d6b0453 meson: switch minimum meson version to 0.58.2, minimum recommended to 0.59.2
Meson 0.58.2 does not need b_staticpic=$pie anymore, and has
stabilized the keyval module.  Remove the workaround and use a few
replacements for features deprecated in the 0.57.0 release cycle.

One feature that we would like to use is passing dependencies to
summary.  However, that was broken in 0.59.0 and 0.59.1.  Therefore,
use the embedded Meson if the host has anything older than 0.59.2,
but allow --meson= to use 0.58.2.

69c4c5c1c4 meson: bump submodule to 0.59.2
The update to 0.57 has been delayed due to it causing warnings for
some actual issues, but it brings in important bugfixes and new
features.  0.58 also brings in a bugfix that is useful for modinfo.

Important bugfixes:

- 0.57: https://github.com/mesonbuild/meson/pull/7760, build: use PIE
objects for non-PIC static libraries if b_pie=true

- 0.57: https://github.com/mesonbuild/meson/pull/7900, thus avoiding
unnecessary rebuilds after running meson.

- 0.58.2: https://github.com/mesonbuild/meson/pull/8900, fixes for
passing extract_objects() to custom_target (useful for modinfo)

Features:

- 0.57: the keyval module has now been stabilized

- 0.57: env argument to custom_target (useful for hexagon)

- 0.57: Feature parity between "meson test" and QEMU's TAP driver

- 0.57: https://github.com/mesonbuild/meson/pull/8231, allows bringing
back version numbers in the configuration summary

- 0.59: Utility methods for feature objects

the default value for the AppleSMC device. The OSK query operation
doesn't require administrator privileges and can be executed by any user
on the system. This patch is based on open-source code from Apple, just
like the implementation from VirtualBox.

cff03145ed sev/i386: Introduce sev_add_kernel_loader_hashes for measured linux boot
Add the sev_add_kernel_loader_hashes function to calculate the hashes of
the kernel/initrd/cmdline and fill a designated OVMF encrypted hash
table area.  For this to work, OVMF must support an encrypted area to
place the data which is advertised via a special GUID in the OVMF reset
table.

The hashes of each of the files is calculated (or the string in the case
of the cmdline with trailing '\0' included).  Each entry in the hashes
table is GUID identified and since they're passed through the
sev_encrypt_flash interface, the hashes will be accumulated by the AMD
PSP measurement (SEV_LAUNCH_MEASURE).
