shm_open() creates and opens a new POSIX shared memory object.
A POSIX shared memory object allows creating memory backend with an
associated file descriptor that can be shared with external processes
(e.g. vhost-user).
The new `memory-backend-shm` can be used as an alternative when
`memory-backend-memfd` is not available (Linux only), since shm_open()
should be provided by any POSIX-compliant operating system.
This backend mimics memfd, allocating memory that is practically
anonymous. In theory shm_open() requires a name, but this is allocated
for a short time interval and shm_unlink() is called right after
shm_open(). After that, only fd is shared with external processes
(e.g., vhost-user) as if it were associated with anonymous memory.
In the future we may also allow the user to specify the name to be
passed to shm_open(), but for now we keep the backend simple, mimicking
anonymous memory such as memfd.

For some use-cases, it is helpful to have more than one UART
available to the guest. If the second UART slot is not already used
for a TrustZone Secure-World-only UART, create it as a NonSecure UART
only when the user provides a serial backend (e.g. via a second
-serial command line option).
This avoids problems where existing guest software only expects a
single UART, and gets confused by the second UART in the DTB. The
major example of this is older EDK2 firmware, which will send the
GRUB bootloader output to UART1 and the guest serial output to UART0.
Users who want to use both UARTs with a guest setup including EDK2
are advised to update to EDK2 release edk2-stable202311 or newer.
(The prebuilt EDK2 blobs QEMU upstream provides are new enough.)
The relevant EDK2 changes are the ones described here:

Different versions of PC machine support different maximum vCPUs, and
even different features have limits on the maximum number of vCPUs (
For example, if x2apic is not enabled in the TCG case, the maximum of
255 vCPUs are supported).
It is difficult to list the maximum vCPUs under all restrictions. Thus,
to avoid confusion, avoid mentioning specific maximum vCPU number
limitations here.

SEV-SNP support relies on a different set of properties/state than the
existing 'sev-guest' object. This patch introduces the 'sev-snp-guest'
object, which can be used to configure an SEV-SNP guest. For example,
a default-configured SEV-SNP guest with no additional information
passed in for use with attestation:
-object sev-snp-guest,id=sev0
or a fully-specified SEV-SNP guest where all spec-defined binary
blobs are passed in as base64-encoded strings:
-object sev-snp-guest,id=sev0, \
policy=0x30000, \
init-flags=0, \
id-block=YWFhYWFhYWFhYWFhYWFhCg==, \
id-auth=CxHK/OKLkXGn/KpAC7Wl1FSiisWDbGTEKz..., \
author-key-enabled=on, \
host-data=LNkCWBRC5CcdGXirbNUV1OrsR28s..., \
guest-visible-workarounds=AA==, \
See the QAPI schema updates included in this patch for more usage
details.
In some cases these blobs may be up to 4096 characters, but this is
generally well below the default limit for linux hosts where
command-line sizes are defined by the sysconf-configurable ARG_MAX
value, which defaults to 2097152 characters for Ubuntu hosts, for
example.

FEAT_WFxT introduces new instructions WFIT and WFET, which are like
the existing WFI and WFE but allow the guest to pass a timeout value
in a register. The instructions will wait for an interrupt/event as
usual, but will also stop waiting when the value of CNTVCT_EL0 is
greater than or equal to the specified timeout value.
We implement WFIT by setting up a timer to expire at the right
point; when the timer expires it sets the EXITTB interrupt, which
will cause the CPU to leave the halted state. If we come out of
halt for some other reason, we unset the pending timer.
We implement WFET as a nop, which is architecturally permitted and
matches the way we currently make WFE a nop.

FEAT_Spec_FPACC is a feature describing speculative behaviour in the
event of a PAC authontication failure when FEAT_FPACCOMBINE is
implemented. FEAT_Spec_FPACC means that the speculative use of
pointers processed by a PAC Authentication is not materially
different in terms of the impact on cached microarchitectural state
(caches, TLBs, etc) between passing and failing of the PAC
Authentication.
QEMU doesn't do speculative execution, so we can advertise
this feature.

FEAT_ETS2 is a tighter set of guarantees about memory ordering
involving translation table walks than the old FEAT_ETS; FEAT_ETS has
been retired from the Arm ARM and the old ID_AA64MMFR1.ETS == 1
now gives no greater guarantees than ETS == 0.
FEAT_ETS2 requires:
* the virtual address of a load or store that appears in program
order after a DSB cannot be translated until after the DSB
completes (section B2.10.9)
* TLB maintenance operations that only affect translations without
execute permission are guaranteed complete after a DSB
(R_BLDZX)
* if a memory access RW2 is ordered-before memory access RW2,
then RW1 is also ordered-before any translation table walk
generated by RW2 that generates a Translation, Address size
or Access flag fault (R_NNFPF, I_CLGHP)
As with FEAT_ETS, QEMU is already compliant, because we do not
reorder translation table walk memory accesses relative to other
memory accesses, and we always guarantee to have finished TLB
maintenance as soon as the TLB op is done.
Update the documentation to list FEAT_ETS2 instead of the
no-longer-existent FEAT_ETS, and update the 'max' CPU ID registers.

As of version DDI0487K.a of the Arm ARM, some architectural features
which previously didn't have official names have been named. Add
these to the list of features which QEMU's TCG emulation supports.
Mostly these are features which we thought of as part of baseline 8.0
support. For SVE and SVE2, the names have been brought into line
with the FEAT_* naming convention of other extensions, and some
sub-components split into separate FEAT_ items. In a few cases (eg
FEAT_CCIDX, FEAT_DPB2) the omission from our list was just an oversight.

GlusterFS+RDMA has been deprecated 8 years ago in commit
0552ff2465 ("block/gluster: deprecate rdma support"):
gluster volfile server fetch happens through unix and/or tcp,
it doesn't support volfile fetch over rdma. The rdma code may
actually mislead, so to make sure things do not break, for now
we fallback to tcp when requested for rdma, with a warning.
If you are wondering how this worked all these days, its the
gluster libgfapi code which handles anything other than unix
transport as socket/tcp, sad but true.
Besides, the whole RDMA subsystem was deprecated in commit
e9a54265f5 ("hw/rdma: Deprecate the pvrdma device and the rdma
subsystem") released in v8.2.

Features supported :
- the 8 STM32L4x5 GPIOs are initialized with their reset values
(except IDR, see below)
- input mode : setting a pin in input mode "externally" (using input
irqs) results in an out irq (transmitted to SYSCFG)
- output mode : setting a bit in ODR sets the corresponding out irq
(if this line is configured in output mode)
- pull-up, pull-down
- push-pull, open-drain
Difference with the real GPIOs :
- Alternate Function and Analog mode aren't implemented :
pins in AF/Analog behave like pins in input mode
- floating pins stay at their last value
- register IDR reset values differ from the real one :
values are coherent with the other registers reset values
and the fact that AF/Analog modes aren't implemented
- setting I/O output speed isn't supported
- locking port bits isn't supported
- ADC function isn't supported
- GPIOH has 16 pins instead of 2 pins
- writing to registers LCKR, AFRL, AFRH and ASCR is ineffective

1. FIFOs are not used. All sends and receives are done directly.
2. Repeated starts are not emulated. Repeated starts can be triggered in real
hardware by sending a new read transfer request in the window time between
transfer active set of write transfer request and done bit set of the same.

Previously not all references mentioned any spec version at all.
Given r3.1 is the current specification available for evaluation at
www.computeexpresslink.org update references to refer to that.
Hopefully this won't become a never ending job.
A few structure definitions have been updated to add new fields.
Defaults of 0 and read only are valid choices for these new DVSEC
registers so go with that for now.
There are additional error codes and some of the 'questions' in
the comments are resolved now.
Update documentation reference to point to the CXL r3.1 specification
with naming closer to what is on the cover.
For cases where there are structure version numbers, add defines
so they can be found next to the register definitions.
