qapi/char: Supply missing member documentation

Since we neglect to document several members of ChardevBackendKind,
their description in the QEMU QMP Reference manual is "Not
documented".  Fix that, and improve the existing member documentation.

hw/nvme: add atomic write support

Adds support for the controller atomic parameters: AWUN and AWUPF. Atomic
Compare and Write Unit (ACWU) is not currently supported.

Writes that adhere to the ACWU and AWUPF parameters are guaranteed to be atomic.

New NVMe QEMU Parameters (See NVMe Specification for details):
       atomic.dn (default off) - Set the value of Disable Normal.
       atomic.awun=UINT16 (default: 0)
       atomic.awupf=UINT16 (default: 0)

By default (Disable Normal set to zero), the maximum atomic write size is
set to the AWUN value.  If Disable Normal is set, the maximum atomic write
size is set to AWUPF.

block/reqlist: allow adding overlapping requests

Allow overlapping request by removing the assert that made it
impossible. There are only two callers:

1. block_copy_task_create()

It already asserts the very same condition before calling
reqlist_init_req().

2. cbw_snapshot_read_lock()

There is no need to have read requests be non-overlapping in
copy-before-write when used for snapshot-access. In fact, there was no
protection against two callers of cbw_snapshot_read_lock() calling
reqlist_init_req() with overlapping ranges and this could lead to an
assertion failure [1].

In particular, with the reproducer script below [0], two
cbw_co_snapshot_block_status() callers could race, with the second
calling reqlist_init_req() before the first one finishes and removes
its conflicting request.

backup: add minimum cluster size to performance options

The type 'size' (corresponding to uint64_t in C) is used in QAPI to
rule out negative inputs and for consistency with already existing
@cluster-size parameters. Since block_copy_calculate_cluster_size()
uses int64_t for its result, a check that the input is not too large
is added in block_copy_state_new() before calling it. The calculation
in block_copy_calculate_cluster_size() is done in the target int64_t
type.

.gitlab-ci.d: Make separate collapsible log sections for build and test

GitLab lets a CI job create its own collapsible log sections by
emitting special escape codes, as documented here:

https://docs.gitlab.com/ee/ci/yaml/script.html#expand-and-collapse-job-log-sections

Use these to make "configure", "build" and "test" separate
collapsible stages.

As recommended by the GitLab docs, we use some shell which is
sourced in the CI job to define functions to emit the magic
lines that start and end sections, to hide the ugliness of
the printf lines from the log.

.gitlab-ci.d: Split build and test in cross build job templates

In the native_build_job_template we have separate steps in the script
for the build and the test steps.  This is helpful because then
gitlab will give separate timestamps in the log view for each, and
you can see how long it took to compile vs how long to test.  In the
templates in crossbuild-template.yml, however, we do both the build
and test in a single 'make' invocation, and so we don't get the
separate timing information.

Split the build and test, in the same way we do in the native build
template.

This will also give us a place to separate out how parallel we want
to do the build by default from how parallel we want to do the tests
by default, which might be helpful in future.

virtio-mem: Add support for suspend+wake-up with plugged memory

Before, the virtio-mem device would unplug all the memory with any reset
of the device, including during the wake-up of the guest from a
suspended state. Due to this, the virtio-mem driver in the Linux kernel
disallowed suspend-to-ram requests in the guest when the
VIRTIO_MEM_F_PERSISTENT_SUSPEND feature is not exposed by QEMU.

This patch adds the code to skip the reset on wake-up and exposes
theVIRTIO_MEM_F_PERSISTENT_SUSPEND feature to the guest kernel driver
when suspending is possible in QEMU (currently only x86).

reset: Use ResetType for qemu_devices_reset() and MachineClass::reset()

Currently, both qemu_devices_reset() and MachineClass::reset() use
ShutdownCause for the reason of the reset. However, the Resettable
interface uses ResetState, so ShutdownCause needs to be translated to
ResetType somewhere. Translating it qemu_devices_reset() makes adding
new reset types harder, as they cannot always be matched to a single
ShutdownCause here, and devices may need to check the ResetType to
determine what to reset and if to reset at all.

This patch moves this translation up in the call stack to
qemu_system_reset() and updates all MachineClass children to use the
ResetType instead.

virtio: kconfig: memory devices are PCI only

Virtio memory devices rely on PCI BARs to expose the contents of memory.
Because of this they cannot be used (yet) with virtio-mmio or virtio-ccw.
In fact the code that is common to virtio-mem and virtio-pmem, which
is in hw/virtio/virtio-md-pci.c, is only included if CONFIG_VIRTIO_PCI
is set.  Reproduce the same condition in the Kconfig file, only allowing
VIRTIO_MEM and VIRTIO_PMEM to be defined if the transport supports it.

Without this patch it is possible to create a configuration with
CONFIG_VIRTIO_PCI=n and CONFIG_VIRTIO_MEM=y, but that causes a
linking failure.

Since kernel v6.11 openrisc has moved from syscall_nr.h file
to syscall.tbl (See 77122bf9e3df ("openrisc: convert to generic syscall

from linux syscall.tbl instead of syscall_nr.h.
New syscall.tbl is imported from linux v6.11 using updated

target/ppc: Fix lxvx/stxvx facility check

The XT check for the lxvx/stxvx instructions is currently
inverted. This was introduced during the move to decodetree.

>From the ISA:
  Chapter 7. Vector-Scalar Extension Facility
  Load VSX Vector Indexed X-form

  lxvx XT,RA,RB
  if TX=0 & MSR.VSX=0 then VSX_Unavailable()
  if TX=1 & MSR.VEC=0 then Vector_Unavailable()
  ...
  Let XT be the value 32×TX + T.

The code currently does the opposite:

    if (paired || a->rt >= 32) {
        REQUIRE_VSX(ctx);
    } else {
        REQUIRE_VECTOR(ctx);
    }

This was already fixed for lxv/stxv at commit "2cc0e449d1 (target/ppc:
Fix lxv/stxv MSR facility check)", but the indexed forms were missed.

tcg/i386: Implement cmp_vec with avx512 insns

The sse/avx instruction set only has EQ and GT as direct comparisons.
Other signed comparisons can be generated from swapping and inversion.
However unsigned comparisons are not available and must be transformed
to signed comparisons by biasing the inputs.

The avx512 instruction set has a complete set of comparisons, with

cmp_vec result by using VPMOVM2*.
