146b5fa505 hw/nvme: fix example serial in documentation
The serial prop on the controller is actually describing the nvme
subsystem serial, which has to be identical for all controllers within
the same nvme subsystem.

This is enforced since commit a859eb9f8f ("hw/nvme: enforce common
serial per subsystem").

Fix the documentation, so that people copying the qemu command line
example won't get an error on qemu start.

5242876f37 hw/arm/virt: dt: add rng-seed property
In 60592cfed2 ("hw/arm/virt: dt: add kaslr-seed property"), the
kaslr-seed property was added, but the equally as important rng-seed
property was forgotten about, which has identical semantics for a
similar purpose. This commit implements it in exactly the same way as
kaslr-seed. It then changes the name of the disabling option to reflect
that this has more to do with randomness vs determinism, rather than
something particular about kaslr.

e74c097638 target/arm: Add cpu properties for SME
Mirror the properties for SVE.  The main difference is
that any arbitrary set of powers of 2 may be supported,
and not the stricter constraints that apply to SVE.

Include a property to control FEAT_SME_FA64, as failing
to restrict the runtime to the proper subset of insns
could be a major point for bugs.

03b39fcf64 hw/cxl: Make the CXL fixed memory window setup a machine parameter.
Paolo Bonzini requested this change to simplify the ongoing
effort to allow machine setup entirely via RPC.

Includes shortening the command line form cxl-fixed-memory-window
to cxl-fmw as the command lines are extremely long even with this
change.

The json change is needed to ensure that there is
a CXLFixedMemoryWindowOptionsList even though the actual
element in the json is never used. Similar to existing
SgxEpcProperties.

Update qemu-options.hx to reflect that this is now a -machine
parameter.  The bulk of -M / -machine parameters are documented
under machine, so use that in preference to M.

Update cxl-test and bios-tables-test to reflect new parameters.

7ac610206a target/arm: Implement FEAT_DoubleFault
The FEAT_DoubleFault extension adds the following:

 * All external aborts on instruction fetches and translation table
   walks for instruction fetches must be synchronous.  For QEMU this
   is already true.

 * SCR_EL3 has a new bit NMEA which disables the masking of SError
   interrupts by PSTATE.A when the SError interrupt is taken to EL3.
   For QEMU we only need to make the bit writable, because we have no
   sources of SError interrupts.

 * SCR_EL3 has a new bit EASE which causes synchronous external
   aborts taken to EL3 to be taken at the same entry point as SError.
   (Note that this does not mean that they are SErrors for purposes
   of PSTATE.A masking or that the syndrome register reports them as
   SErrors: it just means that the vector offset is different.)

 * The existing SCTLR_EL3.IESB has an effective value of 1 when
   SCR_EL3.NMEA is 1.  For QEMU this is a no-op because we don't need
   different behaviour based on IESB (we don't need to do anything to
   ensure that error exceptions are synchronized).

So for QEMU the things we need to change are:
 * Make SCR_EL3.{NMEA,EASE} writable
 * When taking a synchronous external abort at EL3, adjust the
   vector entry point if SCR_EL3.EASE is set
 * Advertise the feature in the ID registers

d507bc3b05 target/arm: Declare support for FEAT_RASv1p1
The architectural feature RASv1p1 introduces the following new
features:
 * new registers ERXPFGCDN_EL1, ERXPFGCTL_EL1 and ERXPFGF_EL1
 * new bits in the fine-grained trap registers that control traps
   for these new registers
 * new trap bits HCR_EL2.FIEN and SCR_EL3.FIEN that control traps
   for ERXPFGCDN_EL1, ERXPFGCTL_EL1, ERXPFGP_EL1
 * a larger number of the ERXMISC<n>_EL1 registers
 * the format of ERR<n>STATUS registers changes

The architecture permits that if ERRIDR_EL1.NUM is 0 (as it is for
QEMU) then all these new registers may UNDEF, and the HCR_EL2.FIEN
and SCR_EL3.FIEN bits may be RES0.  We don't have any ERR<n>STATUS
registers (again, because ERRIDR_EL1.NUM is 0).  QEMU does not yet
implement the fine-grained-trap extension.  So there is nothing we
need to implement to be compliant with the feature spec.  Make the
'max' CPU report the feature in its ID registers, and document it.

75662f36e3 target/arm: Implement FEAT_IDST
The Armv8.4 feature FEAT_IDST specifies that exceptions generated by
read accesses to the feature ID space should report a syndrome code
of 0x18 (EC_SYSTEMREGISTERTRAP) rather than 0x00 (EC_UNCATEGORIZED).
The feature ID space is defined to be:
 op0 == 3, op1 == {0,1,3}, CRn == 0, CRm == {0-7}, op2 == {0-7}

In our implementation we might return the EC_UNCATEGORIZED syndrome
value for a system register access in four cases:
 * no reginfo struct in the hashtable
 * cp_access_ok() fails (ie ri->access doesn't permit the access)
 * ri->accessfn returns CP_ACCESS_TRAP_UNCATEGORIZED at runtime
 * ri->type includes ARM_CP_RAISES_EXC, and the readfn raises
   an UNDEF exception at runtime

We have very few regdefs that set ARM_CP_RAISES_EXC, and none of
them are in the feature ID space. (In the unlikely event that any
are added in future they would need to take care of setting the
correct syndrome themselves.) This patch deals with the other
three cases, and enables FEAT_IDST for AArch64 -cpu max.

    -tpmdev emulator,id=tpm0,chardev=chrtpm \
    -device tpm-tis-device,tpmdev=tpm0

75d08a4072 target/arm: Advertise support for FEAT_BBM level 2
The description in the Arm ARM of the requirements of FEAT_BBM is
admirably clear on the guarantees it provides software, but slightly
more obscure on what that means for implementations.  The description
of the equivalent SMMU feature in the SMMU specification (IHI0070D.b
section 3.21.1) is perhaps a bit more detailed and includes some
example valid implementation choices. (The SMMU version of this
feature is slightly tighter than the CPU version: the CPU is permitted
to raise TLB Conflict aborts in some situations that the SMMU may
not. This doesn't matter for QEMU because we don't want to do TLB
Conflict aborts anyway.)

The informal summary of FEAT_BBM is that it is about permitting an OS
to switch a range of memory between "covered by a huge page" and
"covered by a sequence of normal pages" without having to engage in
the 'break-before-make' dance that has traditionally been
necessary. The 'break-before-make' sequence is:

 * replace the old translation table entry with an invalid entry
 * execute a DSB insn
 * execute a broadcast TLB invalidate insn
 * execute a DSB insn
 * write the new translation table entry
 * execute a DSB insn

The point of this is to ensure that no TLB can simultaneously contain
TLB entries for the old and the new entry, which would traditionally
be UNPREDICTABLE (allowing the CPU to generate a TLB Conflict fault
or to use a random mishmash of values from the old and the new
entry).  FEAT_BBM level 2 says "for the specific case where the only
thing that changed is the size of the block, the TLB is guaranteed
not to do weird things even if there are multiple entries for an
address", which means that software can now do:

 * replace old translation table entry with new entry
 * DSB
 * broadcast TLB invalidate
 * DSB

As the SMMU spec notes, valid ways to do this include:

 * if there are multiple entries in the TLB for an address,
   choose one of them and use it, ignoring the others
 * if there are multiple entries in the TLB for an address,
   throw them all out and do a page table walk to get a new one

QEMU's page table walk implementation for Arm CPUs already meets the
requirements for FEAT_BBM level 2. When we cache an entry in our TCG
TLB, we do so only for the specific (non-huge) page that the address
is in, and there is no way for the TLB data structure to ever have
more than one TLB entry for that page. (We handle huge pages only in
that we track what part of the address space is covered by huge pages
so that a TLB invalidate operation for an address in a huge page
results in an invalidation of the whole TLB.) We ignore the Contiguous
bit in page table entries, so we don't have to do anything for the
parts of FEAT_BBM that deal with changis to the Contiguous bit.

FEAT_BBM level 2 also requires that the nT bit in block descriptors
must be ignored; since commit 39a1fd2528 we do this.

It's therefore safe for QEMU to advertise FEAT_BBM level 2 by
setting ID_AA64MMFR2_EL1.BBM to 2.

f81c60c244 target/arm: Advertise support for FEAT_TTL
The Arm FEAT_TTL architectural feature allows the guest to provide an
optional hint in an AArch64 TLB invalidate operation about which
translation table level holds the leaf entry for the address being
invalidated.  QEMU's TLB implementation doesn't need that hint, and
we correctly ignore the (previously RES0) bits in TLB invalidate
operation values that are now used for the TTL field.  So we can
simply advertise support for it in our 'max' CPU.

7cf3f8d243 hw/arm/virt: Support TCG GICv4
Add support for the TCG GICv4 to the virt board. For the board,
the GICv4 is very similar to the GICv3, with the only difference
being the size of the redistributor frame. The changes here are thus:
 * calculating virt_redist_capacity correctly for GICv4
 * changing various places which were "if GICv3" to be "if not GICv2"
 * the commandline option handling

Note that using GICv4 reduces the maximum possible number of CPUs on
the virt board from 512 to 317, because we can now only fit half as
many redistributors into the redistributor regions we have defined.

ef56c2425e target/arm: Implement FEAT_LPA2
This feature widens physical addresses (and intermediate physical
addresses for 2-stage translation) from 48 to 52 bits, when using
4k or 16k pages.

This introduces the DS bit to TCR_ELx, which is RES0 unless the
page size is enabled and supports LPA2, resulting in the effective
value of DS for a given table walk.  The DS bit changes the format
of the page table descriptor slightly, moving the PS field out to
TCR so that all pages have the same sharability and repurposing
those bits of the page table descriptor for the highest bits of
the output address.

Do not yet enable FEAT_LPA2; we need extra plumbing to avoid
tickling an old kernel bug.

7a928f43d8 target/arm: Implement FEAT_LPA
This feature widens physical addresses (and intermediate physical
addresses for 2-stage translation) from 48 to 52 bits, when using
64k pages.  The only thing left at this point is to handle the
extra bits in the TTBR and in the table descriptors.

Note that PAR_EL1 and HPFAR_EL2 are nominally extended, but we don't
mask out the high bits when writing to those registers, so no changes
are required there.

0af312b6ed target/arm: Implement FEAT_LVA
This feature is relatively small, as it applies only to
64k pages and thus requires no additional changes to the
table descriptor walking algorithm, only a change to the
minimum TSZ (which is the inverse of the maximum virtual
address space size).

Note that this feature widens VBAR_ELx, but we already
treat the register as being 64 bits wide.

95ea96e8b1 hw/arm/virt: KVM: Enable PAuth when supported by the host
Add basic support for Pointer Authentication when running a KVM
guest and that the host supports it, loosely based on the SVE
support.

Although the feature is enabled by default when the host advertises
it, it is possible to disable it by setting the 'pauth=off' CPU
property. The 'pauth' comment is removed from cpu-features.rst,
as it is now common to both TCG and KVM.

Tested on an Apple M1 running 5.16-rc6.

33973e1e1f hw/arm: add control knob to disable kaslr_seed via DTB
Generally a guest needs an external source of randomness to properly
enable things like address space randomisation. However in a trusted
boot environment where the firmware will cryptographically verify
components having random data in the DTB will cause verification to
fail. Add a control knob so we can prevent this being added to the
system DTB.

bbbd9b6ec6 tests/acceptance: rename tests acceptance to tests avocado
In the discussion about renaming the `tests/acceptance` [1], the
conclusion was that the folders inside `tests` are related to the
framework running the tests and not directly related to the type of
the tests.

This changes the folder to `tests/avocado` and adjusts the MAKEFILE, the
CI related files and the documentation.

450e0f28a4 docs: remove non-reference uses of single backticks
The single backtick markup in ReST is the "default role". Currently,
Sphinx's default role is called "content". Sphinx suggests you can use
the "Any" role instead to turn any single-backtick enclosed item into a
cross-reference.

This is useful for things like autodoc for Python docstrings, where it's
often nicer to reference other types with `foo` instead of the more
laborious :py:meth:`foo`. It's also useful in multi-domain cases to
easily reference definitions from other Sphinx domains, such as
referencing C code definitions from outside of kerneldoc comments.

Before we do that, though, we'll need to turn all existing usages of the
"content" role to inline verbatim markup wherever it does not correctly
resolve into a cross-refernece by using double backticks instead.

c2c7f3351a docs/system: move x86 CPU configuration to a separate document
Currently, cpu-models-x86.rst.inc is included in target-i386.rst directly.
To make the toctree more homogeneous when adding more documentation,
include it through a first-class .rst file.

Together with the previous changes to the man page skeletons, this also
frees "===" for the headings, so that cpu-models-x86.rst.inc need not
assume anything about the headings used by target-i386.rst.

f0c1507a2b docs/system: standardize man page sections to --- with overline
Man pages in docs/system use file inclusion heavily.  Use headings with
overlines in the main files, so that the same included file work well
from both manuals and man pages.

This style of heading is a bit more heavy-weight, so it is not used by
the other man pages in interop/ and tools/.  If in the future they
are changed to use include files, for example to avoid having sections
named "synopsis" or "description", they can switch to --- with overline
as well.

06905f6402 docs: standardize directory index to --- with overline
Use a standard heading format for the index.rst file in a directory.
Using overlines makes it clear that individual documents can use e.g.
=== for chapter titles and --- for section titles, as suggested in the
Linux kernel guidelines[1].  They could do it anyway, because documents
included in a toctree are parsed separately and therefore are not tied
to the same conventions for headings.  However, keeping some consistency is
useful since sometimes files are included from multiple places.

Documents within a Sphinx manual are separate files and therefore can use
different conventions for headings.  However, keeping some consistency is
useful so that included files are easy to get right.

This patch uses a standard heading format for book titles, so that it is
obvious when a file sits at the top level toctree of a book or man page.
The heading is irrelevant for man pages, but keep it consistent as well.

Mirror the behavour of /proc/sys/abi/sve_default_vector_length
under the real linux kernel.  We have no way of passing along
a real default across exec like the kernel can, but this is a
decent way of adjusting the startup vector length of a process.

It also updates the truth table to have a new '-dtb' column which is
required by direct kernel boot.

497a30dbb0 qemu-img: Require -F with -b backing image
Back in commit d9f059aa6c (qemu-img: Deprecate use of -b without -F),
we deprecated the ability to create a file with a backing image that
requires qemu to perform format probing.  Qemu can still probe older
files for backwards compatibility, but it is time to finish off the
ability to create such images, due to the potential security risk they
present.  Update a couple of iotests affected by the change.

5a385bf5c5 qcow2: Prohibit backing file changes in 'qemu-img amend'
This was deprecated back in bc5ee6da7 (qcow2: Deprecate use of
qemu-img amend to change backing file), and no one in the meantime has
given any reasons why it should be supported.  Time to make change
attempts a hard error (but for convenience, specifying the _same_
backing chain is not forbidden).  Update a couple of iotests to match.

cdcf766d0b Deprecate pmem=on with non-DAX capable backend file
It is not safe to pretend that emulated NVDIMM supports
persistence while backend actually failed to enable it
and used non-persistent mapping as fall back.
Instead of falling-back, QEMU should be more strict and
error out with clear message that it's not supported.
So if user asks for persistence (pmem=on), they should
store backing file on NVDIMM.

b6ddc6a2b2 ui: Mark the '-no-quit' option as deprecated
It's just a wrapper around the -display ...,window-close=off parameter,
and the name "no-quit" is rather confusing compared to "window-close"
(since there are still other means to quit the emulator), so we should
rather tell our users to use the "window-close" parameter instead.

While we're at it, update the documentation to state that
"-no-quit" is available for GTK, too, not only for SDL.

bb20b86db9 ui: Fix the "-display sdl,window_close=..." parameter
According to the QAPI schema, there is a "-" and not a "_" between
"window" and "close", and we're also talking about "window-close"
in the long parameter description in qemu-options.hx, so we should
make sure that we rather use the variant with the "-" by default
instead of only allowing the one with the "_" here. The old way
still stays enabled for compatibility, but we deprecate it, so that
we can switch to a QAPIfied parameter one day more easily.
