meson: build target libraries with common dependencies
As mentioned in [1], dependencies
were missing when compiling per target libraries, thus breaking
compilation on certain host systems.
We now explicitly add common dependencies to those libraries, so it
solves the problem.

meson: apply target config for picking files from lib{system, user}

However, this is a target configuration, so we need to apply it to the

As well, this prepares merging lib{system, user}_ss with
{system, user}_ss.

meson: merge lib{system, user}_ss with {system, user}_ss
Now that target configuration can be applied to lib{system, user}_ss,
there is no reason to keep that separate from the existing {system,
user}_ss.
The only difference is that we'll now compile those files with
-DCOMPILING_SYSTEM_VS_USER, which removes poison for
CONFIG_USER_ONLY and CONFIG_SOFTMMU, without any other side effect.
We extract existing system/user code common common libraries to
lib{system, user}.
To not break existing meson files, we alias libsystem_ss to system_ss
and libuser_ss to user_ss, so we can do the cleanup in next commit.

hw/timer/hpet: Reorganize register decoding
For Rust HPET, since the commit 519088b7cf6d ("rust: hpet: decode HPET
registers into enums"), it decodes register address by checking if the
register belongs to global register space. And for C HPET, it checks
timer register space first.
While both approaches are fine, it's best to be as consistent as
possible.
Synchronize changes from the rust side to C side.

allowed by KVM.
Besides, sanity check the attribute bits that have not been supported by
QEMU yet. e.g., debug bit, it will be allowed in the future when debug
TD support lands in QEMU.

i386/tdx: Set APIC bus rate to match with what TDX module enforces
TDX advertises core crystal clock with cpuid[0x15] as 25MHz for TD
guests and it's unchangeable from VMM. As a result, TDX guest reads
the APIC timer at the same frequency, 25MHz.
While KVM's default emulated frequency for APIC bus is 1GHz, set the
APIC bus rate to match with TDX explicitly to ensure KVM provide correct
emulated APIC timer for TD guest.

i386/tdvf: Introduce function to parse TDVF metadata
TDX VM needs to boot with its specialized firmware, Trusted Domain
Virtual Firmware (TDVF). QEMU needs to parse TDVF and map it in TD
guest memory prior to running the TDX VM.
A TDVF Metadata in TDVF image describes the structure of firmware.
QEMU refers to it to setup memory for TDVF. Introduce function
tdvf_parse_metadata() to parse the metadata from TDVF image and store
the info of each TDVF section.
TDX metadata is located by a TDX metadata offset block, which is a
GUID-ed structure. The data portion of the GUID structure contains
only an 4-byte field that is the offset of TDX metadata to the end
of firmware file.
Select X86_FW_OVMF when TDX is enable to leverage existing functions
to parse and search OVMF's GUID-ed structures.

For each TDVF sections, QEMU needs to copy the content to guest
private memory via KVM API (KVM_TDX_INIT_MEM_REGION).
Introduce a field @mem_ptr for TdxFirmwareEntry to track the memory
pointer of each TDVF sections. So that QEMU can add/copy them to guest
private memory later.
TDVF sections can be classified into two groups:
- Firmware itself, e.g., TDVF BFV and CFV, that located separately from
guest RAM. Its memory pointer is the bios pointer.
- Sections located at guest RAM, e.g., TEMP_MEM and TD_HOB.
mmap a new memory range for them.
Register a machine_init_done callback to do the stuff.

i386/tdx: Track RAM entries for TDX VM
The RAM of TDX VM can be classified into two types:
- TDX_RAM_UNACCEPTED: default type of TDX memory, which needs to be
accepted by TDX guest before it can be used and will be all-zeros
after being accepted.
- TDX_RAM_ADDED: the RAM that is ADD'ed to TD guest before running, and
can be used directly. E.g., TD HOB and TEMP MEM that needed by TDVF.
Maintain TdxRamEntries[] which grabs the initial RAM info from e820 table
and mark each RAM range as default type TDX_RAM_UNACCEPTED.
Then turn the range of TD HOB and TEMP MEM to TDX_RAM_ADDED since these
ranges will be ADD'ed before TD runs and no need to be accepted runtime.
The TdxRamEntries[] are later used to setup the memory TD resource HOB
that passes memory info from QEMU to TDVF.

Introduce a bool flag, enable_cpuid_0x1f, in CPU for the case that
requires CPUID leaf 0x1f to be exposed to guest.
Introduce a new function x86_has_cpuid_0x1f(), which is the wrapper of
cpu->enable_cpuid_0x1f and x86_has_extended_topo() to check if it needs
to enable cpuid leaf 0x1f for the guest.

features (reported via KVM_GET_SUPPORTED_CPUID) for common VMs being
falsely reported as supported for TDX.
As the first step, initialize the TDX supported CPUID set with all the
configurable CPUID bits. It's not complete because there are other CPUID
bits are supported for TDX but not reported as directly configurable.
E.g. the XFAM related bits, attribute related bits and fixed-1 bits.
They will be handled in the future.
Also, what matters are the CPUID bits related to QEMU's feature word.
Only mask the CPUID leafs which are feature word leaf.

rust: make declaration of dependent crates more consistent
Crates like "bilge" and "libc" can be shared by more than one directory,
so declare them directly in rust/meson.build. While at it, make their
variable names end with "_rs" and always add a subproject() statement
(as that pinpoints the error better if the subproject is missing and
cannot be downloaded).

hw/block: Drop unused nand.c
The nand.c device (TYPE_NAND) is an emulation of a NAND flash memory
chip which was used by the old OMAP boards. No current QEMU board
uses it, and although techically "-device nand,chip-id=0x6b" doesn't
error out, it's not possible to usefully use it from the command
line because the only interface it has is via calling C functions
like nand_setpins() and nand_setio().
The "config OMAP" stanza (used only by the SX1 board) is the only
thing that does "select NAND" to compile in this code, but the SX1
board doesn't actually use the NAND device.
Remove the NAND device code entirely; this is effectively leftover
cleanup from when we dropped the PXA boards and the OMAP boards
other than the sx1.

io: Add helper for setting socket send buffer size
Testing reading and writing from qemu-nbd using a unix domain socket
shows that the platform default send buffer size is too low, leading to
poor performance and hight cpu usage.
Add a helper for setting socket send buffer size to be used in NBD code.
It can also be used in other contexts.
We don't need a helper for receive buffer size since it is not used with
unix domain sockets. This is documented for Linux, and not documented
for macOS.
Failing to set the socket buffer size is not a fatal error, but the
caller may want to warn about the failure.

nbd: Set unix socket send buffer on macOS
On macOS we need to increase unix socket buffers size on the client and
server to get good performance. We set socket buffers on macOS after
connecting or accepting a client connection.
Testing shows that setting socket receive buffer size (SO_RCVBUF) has no
effect on performance, so we set only the send buffer size (SO_SNDBUF).
It seems to work like Linux but not documented.
Testing shows that optimal buffer size is 512k to 4 MiB, depending on
the test case. The difference is very small, so I chose 2 MiB.
I tested reading from qemu-nbd and writing to qemu-nbd with qemu-img and
computing a blkhash with nbdcopy and blksum.
To focus on NBD communication and get less noisy results, I tested
reading and writing to null-co driver. I added a read-pattern option to
the null-co driver to return data full of 0xff:
NULL="json:{'driver': 'raw', 'file': {'driver': 'null-co', 'size': '10g',
'read-pattern': 255}}"
For testing buffer size I added an environment variable for setting the
socket buffer size.

is optimal (12.6 times faster).

nbd: Set unix socket send buffer on Linux
Like macOS we have similar issue on Linux. For TCP socket the send
buffer size is 2626560 bytes (~2.5 MiB) and we get good performance.
However for unix socket the default and maximum buffer size is 212992
bytes (208 KiB) and we see poor performance when using one NBD
connection, up to 4 times slower than macOS on the same machine.
Tracing shows that for every 2 MiB payload (qemu uses 2 MiB io size), we
do 1 recvmsg call with TCP socket, and 10 recvmsg calls with unix
socket.
Fixing this issue requires changing the maximum send buffer size (the
receive buffer size is ignored). This can be done using:
$ cat /etc/sysctl.d/net-mem-max.conf
net.core.wmem_max = 2097152
$ sudo sysctl -p /etc/sysctl.d/net-mem-max.conf
With this we can set the socket buffer size to 2 MiB. With the defaults
the value requested by qemu is clipped to the maximum size and has no
effect.
I tested on 2 machines:
- Fedora 42 VM on MacBook Pro M2 Max
- Dell PowerEdge R640 (Intel(R) Xeon(R) Gold 6230 CPU @ 2.10GHz)
On the older Dell machine we see very little improvement, up to 1.03
higher throughput. On the M2 machine we see up to 2.67 times higher
throughput. The following results are from the M2 machine.

iotests: Improve mirror-sparse on ext4 and xfs
Fiona reported that an ext4 filesystem on top of LVM can sometimes
report over-allocation to du (based on the heuristics the filesystem
is making while observing the contents being mirrored); even though
the contents and actual size matched, about 50% of the time the size
reported by disk_usage was too large by 4k, failing the test. In
auditing other iotests, this is a common problem we've had to deal
with.
Meanwhile, Markus reported that an xfs filesystem reports disk usage
at a default granularity of 1M (so the sparse file occupies 3M, since
it has just over 2M data).

iotests: Filter out ZFS in several tests
Fiona reported that ZFS makes sparse file testing awkward, since:
- it has asynchronous allocation (not even 'fsync $file' makes du see
the desired size; it takes the slower 'fsync -f $file' which is not
appropriate for the tests)
- for tests of fully allocated files, ZFS with compression enabled
still reports smaller disk usage
Add a new _require_disk_usage that quickly probes whether an attempt
to create a sparse 5M file shows as less than 1M usage, while the same
file with -o preallocation=full shows as more than 4M usage without
sync, which should filter out ZFS behavior. Then use it in various
affected tests.
This does not add the new filter on all tests that Fiona is seeing ZFS
failures on, but only those where I could quickly spot that there is
at least one place where the test depends on the output of 'du -b' or
'stat -c %b'.

"endianness" CPU property was hard-wired to "true", see commits
133d23b3ad1 and a88bbb006a52), so the variants that showed up
on the big endian target likely never worked. We deprecated these
non-working machine variants two releases ago, and so far nobody
complained, so it should be fine now to disable them. Hard-wire
the machines to little endian now.

docs: Deprecate the qemu-system-microblazeel binary
The (former big-endian only) binary qemu-system-microblaze can
handle both endiannesses nowadays, so we don't need the separate
qemu-system-microblazeel binary for little endian anymore. Let's
deprecate it to avoid unnecessary compilation and test time in
the future.
