b17a26bc4b i386: Support module_id in X86CPUTopoIDs
Add module_id member in X86CPUTopoIDs.

module_id can be parsed from APIC ID, so also update APIC ID parsing
rule to support module level. With this support, the conversions with
module level between X86CPUTopoIDs, X86CPUTopoInfo and APIC ID are
completed.

module_id can be also generated from cpu topology, and before i386
supports "modules" in smp, the default "modules per die" (modules *
clusters) is only 1, thus the module_id generated in this way is 0,
so that it will not conflict with the module_id generated by APIC ID.

5304873acd i386: Expose module level in CPUID[0x1F]
Linux kernel (from v6.4, with commit edc0a2b595765 ("x86/topology: Fix
erroneous smp_num_siblings on Intel Hybrid platforms") is able to
handle platforms with Module level enumerated via CPUID.1F.

Expose the module level in CPUID[0x1F] if the machine has more than 1
modules.

3568adc995 i386: Support modules_per_die in X86CPUTopoInfo
Support module level in i386 cpu topology structure "X86CPUTopoInfo".

Since x86 does not yet support the "modules" parameter in "-smp",
X86CPUTopoInfo.modules_per_die is currently always 1.

Therefore, the module level width in APIC ID, which can be calculated by
"apicid_bitwidth_for_count(topo_info->modules_per_die)", is always 0 for
now, so we can directly add APIC ID related helpers to support module
level parsing.

In addition, update topology structure in test-x86-topo.c.

6ddeb0ec8c i386/cpu: Introduce bitmap to cache available CPU topology levels
Currently, QEMU checks the specify number of topology domains to detect
if there's extended topology levels (e.g., checking nr_dies).

With this bitmap, the extended CPU topology (the levels other than SMT,
core and package) could be easier to detect without touching the
topology details.

This is also in preparation for the follow-up to decouple CPUID[0x1F]
subleaf with specific topology level.

a44ea3fa7f hw/i386/pc_sysfw: Alias rather than copy isa-bios region
In the -bios case the "isa-bios" memory region is an alias to the BIOS mapped
to the top of the 4G memory boundary. Do the same in the -pflash case, but only
for new machine versions for migration compatibility. This establishes common
behavior and makes pflash commands work in the "isa-bios" region which some
real-world legacy bioses rely on.

Note that in the sev_enabled() case, the "isa-bios" memory region in the -pflash
case will now also point to encrypted memory, just like it already does in the
-bios case.

When running `info mtree` before and after this commit with
`qemu-system-x86_64 -S -drive \
if=pflash,format=raw,readonly=on,file=/usr/share/qemu/bios-256k.bin` and running
`diff -u before.mtree after.mtree` results in the following changes in the
memory tree:

c0fcd6334f ui/console: Use qemu_dmabuf_new() and free() helpers instead
This commit introduces utility functions for the creation and deallocation
of QemuDmaBuf instances. Additionally, it updates all relevant sections
of the codebase to utilize these new utility functions.

v7: remove prefix, "dpy_gl_" from all helpers
    qemu_dmabuf_free() returns without doing anything if input is null
    (Daniel P. Berrangé <berrange@redhat.com>)
    call G_DEFINE_AUTOPTR_CLEANUP_FUNC for qemu_dmabuf_free()
    (Daniel P. Berrangé <berrange@redhat.com>)

v8: Introduction of helpers was removed as those were already added
    by the previous commit

v9: set dmabuf->allow_fences to 'true' when dmabuf is created in
    virtio_gpu_create_dmabuf()/virtio-gpu-udmabuf.c

    removed unnecessary spaces were accidently added in the patch,
    'ui/console: Use qemu_dmabuf_new() a...'

v11: Calling qemu_dmabuf_close was removed as closing dmabuf->fd will be
     done in qemu_dmabuf_free anyway.
     (Daniel P. Berrangé <berrange@redhat.com>)

v12: --- Calling qemu_dmabuf_close separately as qemu_dmabuf_free doesn't
         do it.

     --- 'dmabuf' is now allocated space so it should be freed at the end of
         dbus_scanout_texture

v13: --- Immediately free dmabuf after it is released to prevent possible
         leaking of the ptr
         (Marc-André Lureau <marcandre.lureau@redhat.com>)

     --- Use g_autoptr macro to define *dmabuf for auto clean up instead of
         calling qemu_dmabuf_free
         (Marc-André Lureau <marcandre.lureau@redhat.com>)

v14: --- (vhost-user-gpu) Change qemu_dmabuf_free back to g_clear_pointer
         as it was done because of some misunderstanding (v13).

     --- (vhost-user-gpu) g->dmabuf[m->scanout_id] needs to be set to NULL
         to prevent freed dmabuf to be accessed again in case if(fd==-1)break;
         happens (before new dmabuf is allocated). Otherwise, it would cause
         invalid memory access when the same function is executed. Also NULL
         check should be done before qemu_dmabuf_close (it asserts dmabuf!=NULL.).

6e6ae491da ui/console: new dmabuf.h and dmabuf.c for QemuDmaBuf struct and helpers
New header and source files are added for containing QemuDmaBuf struct
definition and newly introduced helpers for creating/freeing the struct
and accessing its data.

v10: Change the license type for both dmabuf.h and dmabuf.c from MIT to
     GPL to be in line with QEMU's default license

v11: -- Added new helpers, qemu_dmabuf_close for closing dmabuf->fd,
        qemu_dmabuf_dup_fd for duplicating dmabuf->fd
        (Daniel P. Berrangé <berrange@redhat.com>)

     -- Let qemu_dmabuf_fee to call qemu_dmabuf_close before freeing
        the struct to make sure fd is closed.
        (Daniel P. Berrangé <berrange@redhat.com>)

v12: Not closing fd in qemu_dmabuf_free because there are cases fd
     should still be available even after the struct is destroyed
     (e.g. virtio-gpu: res->dmabuf_fd).

0d8caac904 Bump minimum glib version to v2.66
Now that we dropped support for CentOS 8 and Ubuntu 20.04, we can
look into bumping the glib version to a new minimum for further
clean-ups. According to repology.org, available versions are:

 CentOS Stream 9:       2.66.7
 Debian 11:             2.66.8
 Fedora 38:             2.74.1
 Freebsd:               2.78.4
 Homebrew:              2.80.0
 Openbsd:               2.78.4
 OpenSuse leap 15.5:    2.70.5
 pkgsrc_current:        2.78.4
 Ubuntu 22.04:          2.72.1

Thus it should be safe to bump the minimum glib version to 2.66 now.
Version 2.66 comes with new functions for URI parsing which will
allow further clean-ups in the following patches.

d0be0ac2c3 hw/i386: move rtc-reset-reinjection command out of hw/rtc
The rtc-reset-reinjection QMP command is specific to x86, other boards do not
have the ACK tracking functionality that is needed for RTC interrupt
reinjection.  Therefore the QMP command is only included in x86, but
qmp_rtc_reset_reinjection() is implemented by hw/rtc/mc146818rtc.c
and requires tracking of all created RTC devices.  Move the implementation
to hw/i386, so that 1) it is available even if no RTC device exist
2) the only RTC that exists is easily found in x86ms->rtc.

88f5ed7017 xen: register legacy backends via xen_backend_init
It is okay to register legacy backends in the middle of xen_bus_init().
All that the registration does is record the existence of the backend
in xenstore.

This makes it possible to remove them from the build without introducing
undefined symbols in xen_be_init().  It also removes the need for the
backend_register callback, whose only purpose is to avoid registering
nonfunctional backends.

d804ad98f5 hw/loongarch: Rename LoongArchMachineState with LoongArchVirtMachineState
Rename LoongArchMachineState with LoongArchVirtMachineState, and change
variable name LoongArchMachineState *lams with LoongArchVirtMachineState
*lvms.

Rename function specific for virtmachine loongarch_xxx()
with virt_xxx(). However some common functions keep unchanged such as
loongarch_acpi_setup()/loongarch_load_kernel(), since there functions
can be used for real hw boards.

5c5ffec12c hw/i386/x86: Extract x86_isa_bios_init() from x86_bios_rom_init()
The function is inspired by pc_isa_bios_init() and should eventually replace it.
Using x86_isa_bios_init() rather than pc_isa_bios_init() fixes pflash commands
to work in the isa-bios region.

While at it convert the magic number 0x100000 (== 1MiB) to increase readability.
