8d0efbcfa0 docs: build-platforms: refine requirements on Python build dependencies
Historically, the critical dependency for both building and running
QEMU has been the distro packages.  Because QEMU is written in C and C's
package management has been tied to distros (at least if you do not want
to bundle libraries with the binary, otherwise I suppose you could use
something like conda or wrapdb), C dependencies of QEMU would target the
version that is shipped in relatively old but still commonly used distros.

For non-C libraries, however, the situation is different, as these
languages have their own package management tool (cpan, pip, gem, npm,
and so on).  For some of these languages, the amount of dependencies
for even a simple program can easily balloon to the point that many
distros have given up on packaging non-C code.  For this reason, it has
become increasingly normal for developers to download dependencies into
a self-contained local environment, instead of relying on distro packages.

Fortunately, this affects QEMU only at build time, as qemu.git does
not package non-C artifacts such as the qemu.qmp package; but still,
as we make more use of Python, we experience a clash between a support
policy that is written for the C world, and dependencies (both direct
and indirect) that increasingly do not care for the distro versions
and are quick at moving past Python runtime versions that are declared
end-of-life.

For example, Python 3.6 has been EOL'd since December 2021 and Meson 0.62
(released the following March) already dropped support for it.  Yet,
Python 3.6 is the default version of the Python runtime for RHEL/CentOS
8 and SLE 15, respectively the penultimate and the most recent version
of two distros that QEMU would like to support.  (It is also the version
used by Ubuntu 18.04, but QEMU stopped supporting it in April 2022).

There are good reasons to move forward with the deprecation of Python
3.6 in QEMU as well: completing the configure->meson switch (which
requires Meson 0.63), and making the QAPI generator fully typed (which
requires newer versions of not just mypy but also Python, due to PEP563).

Fortunately, these long-term support distros do include newer versions of
the Python runtime.  However, these more recent runtimes only come with
a very small subset of the Python packages that the distro includes.
Because most dependencies are optional tests (avocado, mypy, flake8)
and Meson is bundled with QEMU, the most noticeably missing package is
Sphinx (and the readthedocs theme).  There are four possibilities:

* we change the support policy and stop supporting CentOS 8 and SLE 15;
  not a good idea since CentOS 8 is not an unreasonable distro for us to
  want to continue to support

* we keep supporting Python 3.6 until CentOS 8 and SLE 15 stop being
  supported.  This is a possibility---but we may want to revise the support
  policy anyway because SLE 16 has not even been released, so this would
  mean delaying those desirable reasons for perhaps three years;

* we support Python 3.6 just for building documentation, i.e. we are
  careful not to use Python 3.7+ features in our Sphinx extensions but are
  free to use them elsewhere.  Besides being more complicated to understand
  for developers, this can be quite limiting; parts of the QAPI generator
  run at sphinx-build time, which would exclude one of the areas which
  would benefit from a newer version of the runtime;

* we only support Python 3.7+, which means CentOS 8 CI and users
  have to either install Sphinx from pip or disable documentation.

This proposed update to the support policy chooses the last of these
possibilities.  It does by modifying three aspects of the support
policy:

* it introduces different support periods for *native* vs. *non-native*
  dependencies.  Non-native dependencies are currently Python ones only,
  and for simplicity the policy only mentions Python; however, the concept
  generalizes to other languages with a well-known upstream package
  manager, that users of older distributions can fetch dependencies from;

* it opens up the possibility of taking non-native dependencies from their
  own package index instead of using the version in the distribution.  The
  wording right now is specific to dependencies that are only required at
  build time.  In the future we may have to refine it if, for example, parts
  of QEMU will be written in Rust; in that case, crates would be handled
  in a similar way to submodules and vendored in the release tarballs.

* it mentions specifically that optional build dependencies are excluded
  from the platform policy.  Tools such as mypy don't affect the ability
  to build QEMU and move fast enough that distros cannot standardize on
  a single version of them (for example RHEL9 does not package them at
  all, nor does it run them at rpmbuild time).  In other cases, such as
  cross compilers, we have alternatives.

Right now, non-native dependencies have to be download manually by
running "pip" before "configure".  In the future, it will be desirable
for configure to set up a virtual environment and download them in the
same way that it populates git submodules (but, in this case, without
vendoring them in the release tarballs).

Just like with submodules, this would make things easier for people
that can afford accessing the network in their build environment; the
option to populate the build environment manually would remain for
people whose build machines lack network access.  The change to the
support policy neither requires nor forbids this future change.

90c167a1da docs/about/deprecated: Mark HAXM in QEMU as deprecated
The HAXM project has been retired (see https://github.com/intel/haxm#status),
so we should mark the code in QEMU as deprecated (and finally remove it
unless somebody else picks the project up again - which is quite unlikely
since there are now whpx and hvf on these operating systems, too).

5584e2dbe8 tcg: add perfmap and jitdump
Add ability to dump /tmp/perf-<pid>.map and jit-<pid>.dump.
The first one allows the perf tool to map samples to each individual
translation block. The second one adds the ability to resolve symbol
names, line numbers and inspect JITed code.

Example of use:

    perf record qemu-x86_64 -perfmap ./a.out
    perf report

or

    perf record -k 1 qemu-x86_64 -jitdump ./a.out
    DEBUGINFOD_URLS= perf inject -j -i perf.data -o perf.data.jitted
    perf report -i perf.data.jitted

9be8a82c0e {hw/i2c,docs/system/arm}: Allwinner TWI/I2C Emulation
This patch implements Allwinner TWI/I2C controller emulation. Only
master-mode functionality is implemented.

The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is
first part enabling the TWI/I2C bus operation.

Since both Allwinner A10 and H3 use the same module, it is added for
both boards.

Docs are also updated for Cubieboard and Orangepi-PC board to indicate
I2C availability.

76a2f554c1 block-coroutine-wrapper.py: introduce co_wrapper
This new annotation starts just a function wrapper that creates
a new coroutine. It assumes the caller is not a coroutine.
It will be the default annotation to be used in the future.

This is much better as c_w_mixed, because it is clear if the caller
is a coroutine or not, and provides the advantage of automating
the code creation. In the future all c_w_mixed functions will be
substituted by co_wrapper.

6a48c64eec hw/arm/virt: Add properties to disable high memory regions
The 3 high memory regions are usually enabled by default, but they may
be not used. For example, VIRT_HIGH_GIC_REDIST2 isn't needed by GICv2.
This leads to waste in the PA space.

Add properties ("highmem-redists", "highmem-ecam", "highmem-mmio") to
allow users selectively disable them if needed. After that, the high
memory region for GICv3 or GICv4 redistributor can be disabled by user,
the number of maximal supported CPUs needs to be calculated based on
'vms->highmem_redists'. The follow-up error message is also improved
to indicate if the high memory region for GICv3 and GICv4 has been
enabled or not.

f40408a9fe hw/arm/virt: Add 'compact-highmem' property
After the improvement to high memory region address assignment is
applied, the memory layout can be changed, introducing possible
migration breakage. For example, VIRT_HIGH_PCIE_MMIO memory region
is disabled or enabled when the optimization is applied or not, with
the following configuration. The configuration is only achievable by
modifying the source code until more properties are added to allow
users selectively disable those high memory regions.

  pa_bits              = 40;
  vms->highmem_redists = false;
  vms->highmem_ecam    = false;
  vms->highmem_mmio    = true;

  # qemu-system-aarch64 -accel kvm -cpu host    \
    -machine virt-7.2,compact-highmem={on, off} \
    -m 4G,maxmem=511G -monitor stdio

  Region             compact-highmem=off         compact-highmem=on
  ----------------------------------------------------------------
  MEM                [1GB         512GB]        [1GB         512GB]
  HIGH_GIC_REDISTS2  [512GB       512GB+64MB]   [disabled]
  HIGH_PCIE_ECAM     [512GB+256MB 512GB+512MB]  [disabled]
  HIGH_PCIE_MMIO     [disabled]                 [512GB       1TB]

In order to keep backwords compatibility, we need to disable the
optimization on machine, which is virt-7.1 or ealier than it. It
means the optimization is enabled by default from virt-7.2. Besides,
'compact-highmem' property is added so that the optimization can be
explicitly enabled or disabled on all machine types by users.

44ea9d9be3 qapi: Start to elide redundant has_FOO in generated C
In QAPI, absent optional members are distinct from any present value.
We thus represent an optional schema member FOO as two C members: a
FOO with the member's type, and a bool has_FOO.  Likewise for function
arguments.

However, has_FOO is actually redundant for a pointer-valued FOO, which
can be null only when has_FOO is false, i.e. has_FOO == !!FOO.  Except
for arrays, where we a null FOO can also be a present empty array.

The redundant has_FOO are a nuisance to work with.  Improve the
generator to elide them.  Uses of has_FOO need to be replaced as
follows.

Tests of has_FOO become the equivalent comparison of FOO with null.
For brevity, this is commonly done by implicit conversion to bool.

Assignments to has_FOO get dropped.

Likewise for arguments to has_FOO parameters.

Beware: code may violate the invariant has_FOO == !!FOO before the
transformation, and get away with it.  The above transformation can
then break things.  Two cases:

* Absent: if code ignores FOO entirely when !has_FOO (except for
  freeing it if necessary), even non-null / uninitialized FOO works.
  Such code is known to exist.

* Present: if code ignores FOO entirely when has_FOO, even null FOO
  works.  Such code should not exist.

In both cases, replacing tests of has_FOO by FOO reverts their sense.
We have to fix the value of FOO then.

To facilitate review of the necessary updates to handwritten code, add
means to opt out of this change, and opt out for all QAPI schema
modules where the change requires updates to handwritten code.  The
next few commits will remove these opt-outs in reviewable chunks, then
drop the means to opt out.

ca127fe96d docs/devel: simplify the minimal checklist
The bullet points are quite long and contain process tips. Move those
bits of the bullet to the relevant sections and link to them. Use a
table for nicer formatting of the checklist.

668725ce6b docs/devel: add a maintainers section to development process
We don't currently have a clear place in the documentation to describe
the roles and responsibilities of a maintainer. Lets create one so we
can. I've moved a few small bits out of other files to try and keep
everything in one place.

1b7a07c441 acpi/tests/avocado/bits: some misc fixes
Most of the changes are trivial. The bits test timeout has now been increased
to 200 seconds in order to accommodate slower systems and fewer unnecessary
failures. Removed of the reference to non-existent README file in docs. Some
minor corrections in the doc file.

This queue has the second part of the ppc4xx_sdram cleanups, doorbell
 instructions for POWER8,  new pflash handling for the e500 machine and a
 Radix MMU regression fix.
 
 It also has a lot of performance optimizations in the PowerPC emulation
 done by the researchers of the Eldorado institute. Between using gvec
 for VMX/VSX instructions, a full rework of the interrupt model and PMU
 optimizations, they managed to drastically speed up the emulation of
 powernv8/9/10 machines.  Here's an example with avocado tests:
 
 - with master:
 
 tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8:
 PASS (38.89 s)
 tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9:

 Other ppc machines, like pseries, also had a noticeable performance
 boost.

63e4bf8e84 hw/ppc/e500: Implement pflash handling
Allows e500 boards to have their root file system reside on flash using
only builtin devices located in the eLBC memory region.

Note that the flash memory area is only created when a -pflash argument is
given, and that the size is determined by the given file. The idea is to
put users into control.

The documentation suggests that there is a qemu-system-ppc32 binary
while the 32 bit version is actually just named qemu-system-ppc. Settle
on qemu-system-ppc64 which also works for 32 bit machines and causes
less clutter in the documentation.

310616d367 hw/core/resettable: fix reset level counting
The code for handling the reset level count in the Resettable code
has two issues:

The reset count is only decremented for the 1->0 case.  This means
that if there's ever a nested reset that takes the count to 2 then it
will never again be decremented.  Eventually the count will exceed
the '50' limit in resettable_phase_enter() and QEMU will trip over
the assertion failure.  The repro case in issue 1266 is an example of
this that happens now the SCSI subsystem uses three-phase reset.

Secondly, the count is decremented only after the exit phase handler
is called.  Moving the reset count decrement from "just after" to
"just before" calling the exit phase handler allows
resettable_is_in_reset() to return false during the handler
execution.

This simplifies reset handling in resettable devices.  Typically, a
function that updates the device state will just need to read the
current reset state and not anymore treat the "in a reset-exit
transition" as a special case.

Note that the semantics change to the *_is_in_reset() functions
will have no effect on the current codebase, because only two
devices (hw/char/cadence_uart.c and hw/misc/zynq_sclr.c) currently
call those functions, and in neither case do they do it from the
device's exit phase methed.

e4c93e44ab target/arm: Implement FEAT_E0PD
FEAT_E0PD adds new bits E0PD0 and E0PD1 to TCR_EL1, which allow the
OS to forbid EL0 access to half of the address space.  Since this is
an EL0-specific variation on the existing TCR_ELx.{EPD0,EPD1}, we can
implement it entirely in aa64_va_parameters().

This requires moving the existing regime_is_user() to internals.h
so that the code in helper.c can get at it.

we already report the granule sizes that way for '-cpu max', and now
we also correctly make attempts to use unimplemented granule sizes
fail, so we can report the support of the feature in the

bab6a301c5 ui/cocoa: Run qemu_init in the main thread
This work is based on:
https://patchew.org/QEMU/20220317125534.38706-1-philippe.mathieu.daude@gmail.com/

Simplify the initialization dance by running qemu_init() in the main
thread before the Cocoa event loop starts. The secondary thread only
runs only qemu_main_loop() and qemu_cleanup().

This fixes a case where addRemovableDevicesMenuItems() calls
qmp_query_block() while expecting the main thread to still hold
the BQL.

Overriding the code after calling qemu_init() is done by dynamically
replacing a function pointer variable, qemu_main when initializing
ui/cocoa, which unifies the static implementation of main() for
builds with ui/cocoa and ones without ui/cocoa.

54ab3c3fee Deprecate 32 bit big-endian MIPS
It's becoming harder to maintain a cross-compiler to test this host
architecture as the old stable Debian 10 ("Buster") moved into LTS
which supports fewer architectures. For now:

  - mark it's deprecation in the docs
  - downgrade the containers to build TCG tests only
  - drop the cross builds from our CI

Users with an appropriate toolchain and user-space can still take
their chances building it.

582a098e6c qga: Replace 'blacklist' command line and config file options by 'block-rpcs'
Let's use a more appropriate wording for this command line and config
file option. The old ones are still accepted for compatibility reasons,
but marked as deprecated now so that it could be removed in a future
version of QEMU.

This change is based on earlier patches from Philippe Mathieu-Daudé,
with the idea for the new option name suggested by BALATON Zoltan.

And while we're at it, replace the "?" in the help text with "help"
since that does not have the problem of conflicting with the wildcard
character of the shells.

3fe72e213e target/arm: Advertise FEAT_ETS for '-cpu max'
The architectural feature FEAT_ETS (Enhanced Translation
Synchronization) is a set of tightened guarantees about memory
ordering involving translation table walks:

 * if memory access RW1 is ordered-before memory access RW2 then it
   is also ordered-before any translation table walk generated by RW2
   that generates a translation fault, address size fault or access
   fault

 * TLB maintenance on non-exec-permission translations is guaranteed
   complete after a DSB (ie it does not need the context
   synchronization event that you have to have if you don’t have
   FEAT_ETS)

For QEMU’s implementation we don’t reorder translation table walk
accesses, and we guarantee to finish the TLB maintenance as soon as
the TLB op is done (the tlb_flush functions will complete at the end
of the TLB, and TLB ops always end the TB because they’re sysreg
writes).

So we’re already compliant and all we need to do is say so in the ID
registers for the 'max' CPU.

Instead of using feature_not_found(), which is not a good match because
there is no "remedy" to fix the lack of makecontext(), just print a
custom error.

This happens to remove the last use of feature_not_found(), so remove
the definition and the documentation.

These changes match those made in the following libvirt commits:

  2ac78307af docs: Clarify our stance on backported packages
  78cffd450a docs: Spell out our policy concerning minor releases

Since QEMU's platform support policy is based on libvirt's, it
makes sense to mirror these recent changes made to the latter.

The policy is not altered significantly - we're simply spelling
out some rules that were likely already being implicitly
enforced.

b67de91e0d docs: Add caveats for Windows as the build platform
Commit cf60ccc330 ("cutils: Introduce bundle mechanism") introduced
a Python script to populate a bundle directory using os.symlink() to
point to the binaries in the pc-bios directory of the source tree.
Commit 882084a04a ("datadir: Use bundle mechanism") removed previous
logic in pc-bios/meson.build to create a link/copy of pc-bios binaries
in the build tree so os.symlink() is the way to go.

However os.symlink() may fail [1] on Windows if an unprivileged Windows
user started the QEMU build process, which results in QEMU executables
generated in the build tree not able to load the default BIOS/firmware
images due to symbolic links not present in the bundle directory.

This commits updates the documentation by adding such caveats for users
who want to build QEMU on the Windows platform.

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.

cf60ccc330 cutils: Introduce bundle mechanism
Developers often run QEMU without installing. The bundle mechanism
allows to look up files which should be present in installation even in
such a situation.

It is a general mechanism and can find any files in the installation
tree. The build tree will have a new directory, qemu-bundle, to
represent what files the installation tree would have for reference by
the executables.

Note that it abandons compatibility with Windows older than 8. The
extended support for the prior version, 7 ended more than 2 years ago,
and it is unlikely that someone would like to run the latest QEMU on
such an old system.

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.

779d82e1d3 vduse-blk: Add name option
Currently we use 'id' option as the name of VDUSE device.
It's a bit confusing since we use one value for two different
purposes: the ID to identfy the export within QEMU (must be
distinct from any other exports in the same QEMU process, but
can overlap with names used by other processes), and the VDUSE
name to uniquely identify it on the host (must be distinct from
other VDUSE devices on the same host, but can overlap with other
export types like NBD in the same process). To make it clear,
this patch adds a separate 'name' option to specify the VDUSE
name for the vduse-blk export instead.

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.

9323e79f10 Fix 'writeable' typos
We have about 30 instances of the typo/variant spelling 'writeable',
and over 500 of the more common 'writable'.  Standardize on the
latter.

Change produced with:

  sed -i -e 's/\([Ww][Rr][Ii][Tt]\)[Ee]\([Aa][Bb][Ll][Ee]\)/\1\2/g' $(git grep -il writeable)

and then hand-undoing the instance in linux-headers/linux/kvm.h.

Most of these changes are in comments or documentation; the
exceptions are:
 * a local variable in accel/hvf/hvf-accel-ops.c
 * a local variable in accel/kvm/kvm-all.c
 * the PMCR_WRITABLE_MASK macro in target/arm/internals.h
 * the EPT_VIOLATION_GPA_WRITABLE macro in target/i386/hvf/vmcs.h
   (which is never used anywhere)
 * the AR_TYPE_WRITABLE_MASK macro in target/i386/hvf/vmx.h
   (which is never used anywhere)

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.
