It is a common convention in QEMU to return a positive value in case of
success, and a negated errno value in case of error. Unfortunately,
using errno portably in Rust is a bit complicated; on Unix the errno
values are supported natively by io::Error, but on Windows they are not;
so, use the libc crate.
This is a set of utility functions that are used by both chardev and
block layer bindings.

The Open Compute Project [1] includes a Datacenter NVMe
SSD Specification [2]. The most recent version of this specification
(as of November 2024) is 2.6.1. This specification layers on top of
the NVM Express specifications [3] to provide additional
functionality. A key part of of this is the 512 Byte OCP SMART / Health
Information Extended log page that is defined in Section 4.8.6 of the
specification.
We add a controller argument (ocp) that toggles on/off the SMART log
extended structure. To accommodate different vendor specific specifications
like OCP, we add a multiplexing function (nvme_vendor_specific_log) which
will route to the different log functions based on arguments and log ids.
We only return the OCP extended SMART log when the command is 0xC0 and ocp
has been turned on in the nvme argumants.
Though we add the whole nvme SMART log extended structure, we only populate
the physical_media_units_{read,written}, log_page_version and
log_page_uuid.
This patch is based on work done by Joel but has been modified enough
that he requested a co-developed-by tag rather than a signed-off-by.

The MMIO region size required to support virtualized environments with
large PCI BAR regions can exceed the hardcoded limit configured in QEMU.
For example, a VM with multiple NVIDIA Grace-Hopper GPUs passed through
requires more MMIO memory than the amount provided by VIRT_HIGH_PCIE_MMIO
(currently 512GB). Instead of updating VIRT_HIGH_PCIE_MMIO, introduce a
new parameter, highmem-mmio-size, that specifies the MMIO size required
to support the VM configuration.

Although defaulting the handshake limit to 10 seconds was a nice QoI
change to weed out intentionally slow clients, it can interfere with
integration testing done with manual NBD_OPT commands over 'nbdsh
--opt-mode'. Expose a command line option to allow the user to alter
the timeout away from the default. This option is unlikely to be used
in enough scenarios to warrant a short option letter.
The option --handshake-limit intentionally differs from the name of
the constant added in commit fb1c2aaa98 (limit instead of max_secs)
and the QMP name to be added in the next commit; this is because
typing a longer command-line name is undesirable and there is
sufficient --help text to document the units.

The '-old-param' command line option is specific to Arm targets; it
is very briefly documented as "old param mode". What this option
actually does is change the behaviour when directly booting a guest
kernel, so that command line arguments are passed to the kernel using
the extremely old "param_struct" ABI, rather than the newer ATAGS or
even newer DTB mechanisms.
This support was added back in 2007 to support an old vendor kernel
on the akita/terrier board types:
https://mail.gnu.org/archive/html/qemu-devel/2007-07/msg00344.html
Even then, it was an out-of-date mechanism from the kernel's
point of view -- the kernel has had a comment since 2001 marking
it as deprecated. As of mid-2024, the kernel only retained
param_struct support for the RiscPC and Footbridge platforms:
https://lore.kernel.org/linux-arm-kernel/2831c5a6-cfbf-4fe0-b51c-0396e5b0aeb7@app.fastmail.com/

The pxa2xx CPUs are now only useful with user-mode emulation, because
we dropped all the machine types that used them in 9.2. (Technically
you could alse use "-cpu pxa270" with a board model like versatilepb
which doesn't sanity-check the CPU type, but that has never been a
supported config.)
To use them (or iwMMXt emulation) with QEMU user-mode you would need
to explicitly select them with the -cpu option or the QEMU_CPU
environment variable. A google search finds no examples of anybody
doing this in the last decade; I don't believe the GCC folks are
using QEMU to test their iwMMXt codegen either. In fact, GCC is in
the process of dropping support for iwMMXT entirely.
The iwMMXt emulation is thousands of lines of code in QEMU, and
is now the only bit of Arm insn decode which doesn't use decodetree.
We have no way to test or validate changes to it. This code is
just dead weight that is almost certainly not being used by anybody.
Mark it as deprecated.

Some tests have a very long runtime and might run into timeout issues
e.g. when QEMU has been compiled with --enable-debug. Add a decorator
for marking them more easily. Rename the corresponding environment
variable to be more in sync with the other QEMU_TEST_ALLOW_* switches
that we already have, and add a paragraph about it in the documentation.
