Parse the Cargo.toml file, looking for the unexpected_cfgs
configuration. When generating --cfg options from the
config-host.h file, only use those that are included in the
configuration.

Only qemu-api needs access to the symbols in config-host.h. Remove
the temptation to use them elsewhere by limiting the --cfg arguments to
the qemu-api crate.
Per-crate invocation of the script will also be needed to add --check-cfg
options for each crate's features (when more complex, build-time
configurable devices are added in the future).

Right now, using cargo with QEMU requires copying by hand the bindings.rs to the
source tree. Instead, we can use an include file to escape the cage of cargo's
mandated source directory structure.
By running cargo within meson's "devenv" and adding a MESON_BUILD_ROOT
environment variable, it is easy for build.rs to find the file. However, the
file must be symlinked into cargo's output directory for rust-analyzer to find
it.

We might have more uses for --cfg MESON, even though right now it's only
qemu-api that has generated files. Since we're going to add more flags
to the add_project_arguments calls for Rust, it makes sense to also add
--cfg MESON everywhere.

qemu_chardev_set_replay() was being called in chardev creation to

balloon_stats_get_all will iterate over guest stats upto the max
VIRTIO_BALLOON_S_NR value, calling visit_type_uint64 to populate
the QObject dict. The dict keys are obtained from the static
array balloon_stat_names which is VIRTIO_BALLOON_S_NR in size.
Unfortunately the way that array is declared results in any
unassigned stats getting a NULL name, which will then cause
visit_type_uint64 to trigger an assert in qobject_output_add_obj.
The balloon_stat_names array was fortunately fully populated with
names until recently:
commit 0d2eeef77a33315187df8519491a900bde4a3d83
Author: Bibo Mao <maobibo@loongson.cn>
Date: Mon Oct 28 10:38:09 2024 +0800
linux-headers: Update to Linux v6.12-rc5
pulled a change to include/standard-headers/linux/virtio_balloon.h
which increased VIRTIO_BALLOON_S_NR by 6, and failed to add the new
names to balloon_stat_names.
This commit fills in the missing names, and uses a static assert to
guarantee that any future changes to VIRTIO_BALLOON_S_NR will cause
a build failure until balloon_stat_names is updated.
This problem was detected by the Cockpit Project's automated
integration tests on QEMU 9.2.0-rc1.

The 'pci-vga' device allow setting a 'big-endian-framebuffer'
property since commit 3c2784fc864 ("vga: Expose framebuffer
byteorder as a QOM property"). Similarly, the 'virtio-vga'
device since commit 8be61ce2ce3 ("virtio-vga: implement
big-endian-framebuffer property").
Both call vga_common_reset() in their reset handler, respectively
pci_secondary_vga_reset() and virtio_vga_base_reset_hold(), which
reset 'big_endian_fb', overwritting the property. This is not
correct: the hardware is expected to keep its configured
endianness during resets.
Move 'big_endian_fb' assignment from vga_common_reset() to
vga_common_init() which is called once when the common VGA state
is initialized.

In riscv_cpu_do_interrupt() we use the 'cause' value we got out of
cs->exception as a shift value. However this value can be larger
than 31, which means that "1 << cause" is undefined behaviour,
because we do the shift on an 'int' type.
This causes the undefined behaviour sanitizer to complain
on one of the check-tcg tests:

We used to only have a single UART on the platform and it was located at
address 0x90000000. When the number of UARTs was increased to 4, the
first UART remained at it's location, but instead of being the first one
to be registered, it became the last.
This caused QEMU to pick 0x90000300 as the default UART, which broke
software that hardcoded the address of 0x90000000 and expected it's
output to be visible when the user configured only a single console.
This caused regressions[1] in the barebox test suite when updating to a
newer QEMU. As there seems to be no good reason to register the UARTs in
inverse order, let's register them by ascending address, so existing
software can remain oblivious to the additional UART ports.
Changing the order of uart registration alone breaks Linux which
was choosing the UART at 0x90000300 as the default for ttyS0. To fix
Linux we fix three things in the device tree:
1. Define stdout-path only one time for the first registered UART
instead of incorrectly defining for each UART.
2. Change the UART alias name from 'uart0' to 'serial0' as almost all
Linux tty drivers look for an alias starting with "serial".
3. Add the UART nodes so they appear in the final DTB in the
order starting with the lowest address and working upwards.
In summary these changes mean that the QEMU default UART (serial_hd(0))
is now setup where:
* serial_hd(0) is the lowest-address UART
* serial_hd(0) is listed first in the DTB
* serial_hd(0) is the /chosen/stdout-path one
* the /aliases/serial0 alias points at serial_hd(0)

In the existing design, TTCR is prone to undercounting when running in
continuous mode. This manifests as a timer interrupt appearing to
trigger a few cycles prior to the deadline set in SPR_TTMR_TP.
When the timer triggers, the virtual time delta in nanoseconds between
the time when the timer was set, and when it triggers is calculated.
This nanoseconds value is then divided by TIMER_PERIOD (50) to compute
an increment of cycles to apply to TTCR.
However, this calculation rounds down the number of cycles causing the
undercounting.
A simplistic solution would be to instead round up the number of cycles,
however this will result in the accumulation of timing error over time.
This patch corrects the issue by calculating the time delta in
nanoseconds between when the timer was last reset and the timer event.
This approach allows the TTCR value to be rounded up, but without
accumulating error over time.

Allthough the size of MAX_MUX is equal to 4 and likely will never
change, this patch changes type of constant to unsigned long to
be on the safe side.
Also add a static compile check that MAX_MUX never bigger than
`sizeof(d->mux_bitset) * BITS_PER_BYTE`.

With a valid file ID (FID) of an open file, it should be possible to send
a 'Tgettattr' 9p request and successfully receive a 'Rgetattr' response,
even if the file has been removed in the meantime. Currently this would
fail with ENOENT.
I.e. this fixes the following misbehaviour with a 9p Linux client:
open("/home/tst/filename", O_RDWR|O_CREAT|O_EXCL, 0600) = 3
unlink("/home/tst/filename") = 0
fstat(3, 0x23aa1a8) = -1 ENOENT (No such file or directory)
Expected results:
open("/home/tst/filename", O_RDWR|O_CREAT|O_EXCL, 0600) = 3
unlink("/home/tst/filename") = 0
fstat(3, {st_mode=S_IFREG|0600, st_size=0, ...}) = 0
This is because 9p server is always using a path name based lstat() call
which fails as soon as the file got removed. So to fix this, use fstat()
whenever we have an open file descriptor already.

After removing a file from the file system, we should still be able to
work with the file if we already had it open before removal.
As a first step we verify that it is possible to write to an unlinked
file, as this is what already works. This test is extended later on
after having fixed other use cases after unlink that are not working
yet.

Host drivers do not necessarily set cdb_len in megasas io commands.
With commits 6d1511cea0 ("scsi: Reject commands if the CDB length
exceeds buf_len") and fe9d8927e2 ("scsi: Add buf_len parameter to
scsi_req_new()"), this results in failures to boot Linux from affected
SCSI drives because cdb_len is set to 0 by the host driver.
Set the cdb length to its actual size to solve the problem.

Hvf on x86 only supported 2MiB large pages, but never bothered to strip
out the 1GiB page size capability from -cpu host. With QEMU 8.0.0 this
became a problem because OVMF started to use 1GiB pages by default.
Let's just unconditionally add 1GiB page walk support to the walker.
With this fix applied, I can successfully run OVMF again.

Commit b12cb3819 (amd_iommu: Check APIC ID > 255 for XTSup) throws
linking error for the `kvm_enable_x2apic` when kvm is disabled
and Clang is used for compilation.
This issue comes up because Clang does not remove the function callsite
(kvm_enable_x2apic in this case) during optimization when if condition
have variable. Intel IOMMU driver solves this issue by creating separate
if condition for checking variables, which causes call site being
optimized away by virtue of `kvm_irqchip_is_split()` being defined as 0.
Implement same solution for the AMD driver.

According to our support policy, we only support the two latest
major versions of macOS, and we already removed compatibility code
for older versions. However, it's still possible that people install
an older version of XCode on a recent version of macOS - which won't
be able to compile QEMU anymore, see for example the ticket here:
https://gitlab.com/qemu-project/qemu/-/issues/2694
Thus let's set the expectations right and refuse older versions of
XCode that do not match the two latest versions of macOS anymore.

There is a bug in the process of resolving the serial port base address
in the fdt of the loongarch VM UEFI. When both serial port information
and rng-seed information are chosen in the fdt, there is a probability
that the serial port base address cannot be resolved correctly.
This problem can be fixed by updating UEFI.
