ca5765c852 meson: qga: do not use deprecated meson.build_root()
The function will return the build root of the parent project if called from a
subproject; that is irrelevant for QEMU's usage but rarely desirable, and
therefore the function was deprecated and replaced by two functions
project_build_root() and global_build_root().  Replace it with the former.

f4c66f1705 tests: use tests/venv to run basevm.py-based scripts
This patch co-opts the virtual environment being used by avocado tests
to also run the basevm.py tests. This is being done in preparation for
for the qemu.qmp package being removed from qemu.git.

As part of the change, remove any sys.path() hacks and treat "qemu" as a
normal third-party import.

0e7647aa8a tests: install "qemu" namespace package into venv
This patch adds the "qemu" namespace package to the $build/tests/venv
directory. It does so in "editable" mode, which means that changes to
the source python directory will actively be reflected by the venv.

This patch also then removes any sys.path hacking from the avocado test
scripts directly. By doing this, the environment of where to find these
packages is managed entirely by the virtual environment and not by the
scripts themselves.

caa0f7cbaf tests: add "TESTS_PYTHON" variable to Makefile
This is a convenience feature: $(PYTHON) points to the Python executable
we were instructed to use by the configure script. We use that Python to
create a virtual environment with the "check-venv" target in
tests/Makefile.include.

$(TESTS_PYTHON) points to the Python executable belonging to the virtual
environment tied to the build. This Python executable is a symlink to
the binary used to create the venv, which will be the version provided
at configure time.

Using $(TESTS_PYTHON) therefore uses the $(PYTHON) executable, but with
paths modified to use packages installed to the venv.

d7caf13b5f x86: cpu: fixup number of addressable IDs for logical processors sharing cache
When QEMU is started with '-cpu host,host-cache-info=on', it will
passthrough host's number of logical processors sharing cache and
number of processor cores in the physical package. QEMU already
fixes up the later to correctly reflect number of configured cores
for VM, however number of logical processors sharing cache is still
comes from host CPU, which confuses guest started with:

       -machine q35,accel=kvm \
       -cpu host,host-cache-info=on,l3-cache=off \
       -smp 20,sockets=2,dies=1,cores=10,threads=1  \
       -numa node,nodeid=0,memdev=ram-node0 \
       -numa node,nodeid=1,memdev=ram-node1 \
       -numa cpu,socket-id=0,node-id=0 \
       -numa cpu,socket-id=1,node-id=1

on 2 socket Xeon 4210R host with 10 cores per socket
with CPUID[04H]:
      ...
        --- cache 3 ---
      cache type                           = unified cache (3)

      maximum IDs for cores in pkg         = 0xf (15)
      ...
that doesn't match number of logical processors VM was
configured with and as result RHEL 9.0 guest complains:

Fix it by capping max number of logical processors to vcpus/socket

24ce7aa77d modules: introduces module_kconfig directive
module_kconfig is a new directive that should be used with module_obj
whenever that module depends on the Kconfig to be enabled.

When the module is enabled in Kconfig we are sure that its dependencies
will be enabled as well, thus the module will be loaded without any
problem.

The correct way to use module_kconfig is by passing the Kconfig option
to module_kconfig (or the *config-devices.mak without CONFIG_).

9f9dcb96a4 target/i386/tcg: Fix masking of real-mode addresses with A20 bit
The correct A20 masking is done if paging is enabled (protected mode) but it
seems to have been forgotten in real mode. For example from the AMD64 APM Vol. 2
section 1.2.4:

> If the sum of the segment base and effective address carries over into bit 20,
> that bit can be optionally truncated to mimic the 20-bit address wrapping of the
> 8086 processor by using the A20M# input signal to mask the A20 address bit.

Most BIOSes will enable the A20 line on boot, but I found by disabling the A20 line
afterwards, the correct wrapping wasn't taking place.

`handle_mmu_fault' in target/i386/tcg/sysemu/excp_helper.c seems to be the culprit.
In real mode, it fills the TLB with the raw unmasked address. However, for the
protected mode, the `mmu_translate' function does the correct A20 masking.

The fix then should be to just apply the A20 mask in the first branch of the if
statement.

d7fe639cab hw/nvme: add new command abort case
NVMe command set specification for end-to-end data protection formatted
namespace states:

    o If the Reference Tag Check bit of the PRCHK field is set to ‘1’ and
      the namespace is formatted for Type 3 protection, then the
      controller:
          ▪ should not compare the protection Information Reference Tag
            field to the computed reference tag; and
          ▪ may ignore the ILBRT and EILBRT fields. If a command is
            aborted as a result of the Reference Tag Check bit of the
            PRCHK field being set to ‘1’, then that command should be
            aborted with a status code of Invalid Protection Information,
            but may be aborted with a status code of Invalid Field in
            Command.

Currently qemu compares reftag in the nvme_dif_prchk function whenever
Reference Tag Check bit is set in the command. For type 3 namespaces
however, caller of nvme_dif_prchk - nvme_dif_check does not increment
reftag for each subsequent logical block. That way commands incorporating
more than one logical block for type 3 formatted namespaces with reftag
check bit set, always fail with End-to-end Reference Tag Check Error.
Comply with spec by handling case of set Reference Tag Check
bit in the type 3 formatted namespace.

bd9f371c6f hw/nvme: do not auto-generate uuid
Do not default to generate an UUID for namespaces if it is not
explicitly specified.

This is a technically a breaking change in behavior. However, since the
UUID changes on every VM launch, it is not spec compliant and is of
little use since the UUID cannot be used reliably anyway and the
behavior prior to this patch must be considered buggy.

We cannot provide auto-generated unique or persistent namespace
identifiers (EUI64, NGUID, UUID) easily. Since 6.1, namespaces have been
assigned a generated EUI64 of the form "52:54:00:<namespace counter>".
This is will be unique within a QEMU instance, but not globally.

Revert that this is assigned automatically and immediately deprecate the
compatibility parameter. Users can opt-in to this with the
`eui64-default=on` device parameter or set it explicitly with
`eui64=UINT64`.
