Philippe Mathieu-Daudé fc30abf846 sysemu/kvm: Restrict kvm_has_pit_state2() to x86 targets
kvm_has_pit_state2() is only defined for x86 targets (in
target/i386/kvm/kvm.c). Its declaration is pointless on
all other targets. Have it return a boolean.

Philippe Mathieu-Daudé 1f49d47661 sysemu/kvm: Restrict kvm_get_apic_state() to x86 targets
kvm_get_apic_state() is only defined for x86 targets (in
hw/i386/kvm/apic.c). Its declaration is pointless on all
other targets.

Since we include "linux-headers/asm-x86/kvm.h", no need
to forward-declare 'struct kvm_lapic_state'.

Philippe Mathieu-Daudé 3adce820cf target/i386: Remove unused KVM stubs
All these functions:

 - kvm_arch_get_supported_cpuid()
 - kvm_has_smm(()
 - kvm_hyperv_expand_features()
 - kvm_set_max_apic_id()

are called after checking for kvm_enabled(), which is
false when KVM is not built. Since the compiler elides
these functions, their stubs are not used and can be
removed.

Paolo Bonzini ca056f4499 Python: Drop support for Python 3.7
Debian 10 is not anymore a supported distro, since Debian 12 was
released on June 10, 2023.  Our supported build platforms as of today
all support at least 3.8 (and all of them except for Ubuntu 20.04
support 3.9):

openSUSE Leap 15.5: 3.6.15 (3.11.2)
CentOS Stream 8:    3.6.8  (3.8.13, 3.9.16, 3.11.4)
CentOS Stream 9:    3.9.17 (3.11.4)
Fedora 37:          3.11.4
Fedora 38:          3.11.4
Debian 11:          3.9.2
Debian 12:          3.11.2
Alpine 3.14, 3.15:  3.9.16
Alpine 3.16, 3.17:  3.10.10
Ubuntu 20.04 LTS:   3.8.10
Ubuntu 22.04 LTS:   3.10.12
NetBSD 9.3:         3.9.13*
FreeBSD 12.4:       3.9.16
FreeBSD 13.1:       3.9.18
OpenBSD 7.2:        3.9.17

Note: NetBSD does not appear to have a default meta-package, but offers
several options, the lowest of which is 3.7.15. However, "python39"
appears to be a pre-requisite to one of the other packages we request
in tests/vm/netbsd.

Since it is safe under our supported platform policy, bump our
minimum supported version of Python to 3.8.  The two most interesting
features to have by default include:

- the importlib.metadata module, whose lack is responsible for over 100
  lines of code in mkvenv.py

- improvements to asyncio, for example asyncio.CancelledError
  inherits from BaseException rather than Exception

In addition, code can now use the assignment operator ':='

Because mypy now learns about importlib.metadata, a small change to
mkvenv.py is needed to pass type checking.

There are no config-host.mak symbols anymore that are needed in
config-host.h; the only symbols that are included in config_host_data via
the foreach loop are:

- CONFIG_DEFAULT_TARGETS, which is not used by C code.

- CONFIG_TCG and CONFIG_TCG_INTERPRETER, which are not part of config-host.mak

So, list these two symbols explicitly.

Paolo Bonzini bafe78ad3b contrib/plugins: use an independent makefile
The initial reason to write this patch was to remove the last use of
CONFIG_DEBUG_TCG from the makefiles; the flags to use to build TCG
plugins are unrelated to --enable-debug-tcg, and instead they should
be the same as those used to build emulators (the plugins are not build
via meson for demonstration reasons only).

However, since contrib/plugins/Makefile is also the last case of doing
a compilation job using config-host.mak, go a step further and make it
use a completely separate configuration file, removing all references
to compilers from the toplevel config-host.mak.  Clean up references to
empty variables, and use .SECONDARY so that intermediate object files
are not deleted.

While at it, clarify that --host-cc is not obeyed anyway when _not_

Paolo Bonzini 07c4523c6c contrib/plugins: remove -soname argument
-soname is not needed for runtime-loaded modules.  For example, Meson says:

            if not isinstance(target, build.SharedModule) or target.force_soname:
                # Add -Wl,-soname arguments on Linux, -install_name on OS X
                commands += linker.get_soname_args(
                    self.environment, target.prefix, target.name, target.suffix,
                    target.soversion, target.darwin_versions)

(force_soname is set is shared modules are linked into a build target, which is not
the case here.

Michael Tokarev 1a1dd721fc softmmu/vl.c: inline include/qemu/qemu-options.h into vl.c
qemu-options.h just includes qemu-options.def with some #defines.
We already do this in vl.c in other place. Since no other file
includes qemu-options.h anymore, just inline it in vl.c.

This effectively reverts second half of commit 59a5264b99.

Michael Tokarev 8a768db16a os-posix.c, softmmu/vl.c: move os_parse_cmd_args() into qemu_init()
This will stop linking softmmu-specific os_parse_cmd_args() into every
qemu executable which happens to use other functions from os-posix.c,
such as os_set_line_buffering() or os_setup_signal_handling().

Also, since there's no win32-specific options, *all* option parsing is
now done in softmmu/vl.c:qemu_init(), which is easier to read without
extra indirection, - all options are in the single function now.

This effectively reverts commit 59a5264b99.

Tao Su 3e76bafb28 target/i386: Add support for AMX-COMPLEX in CPUID enumeration
Latest Intel platform GraniteRapids-D introduces AMX-COMPLEX, which adds
two instructions to perform matrix multiplication of two tiles containing
complex elements and accumulate the results into a packed single precision
tile.

AMX-COMPLEX is enumerated via CPUID.(EAX=7,ECX=1):EDX[bit 8]. Add the CPUID
definition for AMX-COMPLEX, AMX-COMPLEX will be enabled automatically when
using '-cpu host' and KVM advertises AMX-COMPLEX to userspace.

Safe signal handling around system calls is mandatory for user-mode
