3c73d590e7 hw/isa/piix4: Decouple INTx-to-LNKx routing which is board-specific
pci_map_irq_fn's in general seem to be board-specific, and PIIX4's
pci_slot_get_pirq() in particular seems very Malta-specific. So move the
latter to malta.c to 1/ keep the board logic in one place and 2/ avoid
PIIX4 to make assumptions about its board.

f021f4e9d2 hw/pci/pci: Factor out pci_bus_map_irqs() from pci_bus_irqs()
pci_bus_irqs() coupled together the assignment of pci_set_irq_fn and
pci_map_irq_fn to a PCI bus. This coupling gets in the way when the
pci_map_irq_fn is board-specific while the pci_set_irq_fn is device-
specific.

For example, both of QEMU's PIIX south bridge models have different
pci_map_irq_fn implementations which are board-specific rather than
device-specific. These implementations should therefore reside in board
code. The pci_set_irq_fn's, however, should stay in the device models
because they access memory internal to the model.

Factoring out pci_bus_map_irqs() from pci_bus_irqs() allows the
assignments to be decoupled, resolving the problem described above.

Note also how pci_vpb_realize() which gets touched in this commit
assigns different pci_map_irq_fn's depending on the board.

1953dfa80e hw/mips/malta: Set PIIX4 IRQ routes in embedded bootloader
Linux kernel expects the northbridge & southbridge chipsets
configured by the BIOS firmware. We emulate that by writing
a tiny bootloader code in write_bootloader().

Upon introduction in commit 5c2b87e34d ("PIIX4 support"),
the PIIX4 configuration space included values specific to
the Malta board.

Set the Malta-specific IRQ routing values in the embedded
bootloader, so the next commit can remove the Malta specific
bits from the PIIX4 PCI-ISA bridge and make it generic
(matching the real hardware).

145e2198d7 hw/mips/gt64xxx_pci: Endian-swap using PCI_HOST_BRIDGE MemoryRegionOps
GT64120's PCI endianness swapping works on little-endian hosts,
but doesn't on big-endian ones. Instead of complicating how
CFGADDR/CFGDATA registers deal with endianness, use the existing
MemoryRegionOps from hw/pci/pci_host.c. Doing so also reduce the
access to internal PCI_HOST_BRIDGE fields.

Map the PCI_HOST_BRIDGE MemoryRegionOps into the corresponding
CFGADDR/CFGDATA regions in the ISD MMIO and remove the unused
code in the current ISD read/write handlers.

Update the mapping when PCI0_CMD register is accessed (in case
the endianness is changed).

This allows using the GT64120 on a big-endian host (and boot
the MIPS Malta machine in little-endian).

8b8437259c hw/display: avoid creating empty loadable modules
When using --disable-virglrenderer, QEMU still creates

  hw-display-virtio-gpu-gl.so
  hw-display-virtio-vga-gl.so
  hw-display-virtio-gpu-pci-gl.so

but when these are loaded, they provide no functionality as the code
which registers types is not compiled in. Funtionally this is
relatively harmless, because QEMU is fine loading a module with no
types.

This is rather confusing for users and OS distro maintainers though,
as they think they have the GL functionality built, but in fact the
module they are looking at provides nothing of value.

The root cause is the use of 'when/if_true' rules when adding sources
to the module source set. If all the rules evaluate to false, then we
have declared the module, but not added anything to it.  We need to
put declaration of the entire module inside a condition based on
existance of the 3rd party library deps that are mandatory.

bd688fc931 accel: introduce accelerator blocker API
This API allows the accelerators to prevent vcpus from issuing
new ioctls while execting a critical section marked with the
accel_ioctl_inhibit_begin/end functions.

Note that all functions submitting ioctls must mark where the
ioctl is being called with accel_{cpu_}ioctl_begin/end().

This API requires the caller to always hold the BQL.
API documentation is in sysemu/accel-blocker.h

Internally, it uses a QemuLockCnt together with a per-CPU QemuLockCnt
(to minimize cache line bouncing) to keep avoid that new ioctls
run when the critical section starts, and a QemuEvent to wait
that all running ioctls finish.

dab30fbef3 acpi: cpuhp: fix guest-visible maximum access size to the legacy reg block
The modern ACPI CPU hotplug interface was introduced in the following
series (aa1dd39ca307..679dd1a957df), released in v2.7.0:

  1  abd49bc2ed docs: update ACPI CPU hotplug spec with new protocol
  2  16bcab97eb pc: piix4/ich9: add 'cpu-hotplug-legacy' property
  3  5e1b5d9388 acpi: cpuhp: add CPU devices AML with _STA method
  4  ac35f13ba8 pc: acpi: introduce AcpiDeviceIfClass.madt_cpu hook
  5  d2238cb678 acpi: cpuhp: implement hot-add parts of CPU hotplug
                  interface
  6  8872c25a26 acpi: cpuhp: implement hot-remove parts of CPU hotplug
                  interface
  7  76623d00ae acpi: cpuhp: add cpu._OST handling
  8  679dd1a957 pc: use new CPU hotplug interface since 2.7 machine type

Before patch#1, "docs/specs/acpi_cpu_hotplug.txt" only specified 1-byte
accesses for the hotplug register block.  Patch#1 preserved the same
restriction for the legacy register block, but:

- it specified DWORD accesses for some of the modern registers,

- in particular, the switch from the legacy block to the modern block
  would require a DWORD write to the *legacy* block.

The latter functionality was then implemented in cpu_status_write()
[hw/acpi/cpu_hotplug.c], in patch#8.

Unfortunately, all DWORD accesses depended on a dormant bug: the one
introduced in earlier commit a014ed07bd ("memory: accept mismatching
sizes in memory_region_access_valid", 2013-05-29); first released in
v1.6.0.  Due to commit a014ed07bd, the DWORD accesses to the *legacy*
CPU hotplug register block would work in spite of the above series *not*
relaxing "valid.max_access_size = 1" in "hw/acpi/cpu_hotplug.c":

> static const MemoryRegionOps AcpiCpuHotplug_ops = {
>     .read = cpu_status_read,
>     .write = cpu_status_write,
>     .endianness = DEVICE_LITTLE_ENDIAN,
>     .valid = {
>         .min_access_size = 1,
>         .max_access_size = 1,
>     },
> };

Later, in commits e6d0c3ce68 ("acpi: cpuhp: introduce 'Command data 2'
field", 2020-01-22) and ae340aa3d2 ("acpi: cpuhp: spec: add typical
usecases", 2020-01-22), first released in v5.0.0, the modern CPU hotplug
interface (including the documentation) was extended with another DWORD
*read* access, namely to the "Command data 2" register, which would be
important for the guest to confirm whether it managed to switch the
register block from legacy to modern.

This functionality too silently depended on the bug from commit
a014ed07bd.

In commit 5d971f9e67 ('memory: Revert "memory: accept mismatching sizes
in memory_region_access_valid"', 2020-06-26), first released in v5.1.0,
the bug from commit a014ed07bd was fixed (the commit was reverted).
That swiftly exposed the bug in "AcpiCpuHotplug_ops", still present from
the v2.7.0 series quoted at the top -- namely the fact that
"valid.max_access_size = 1" didn't match what the guest was supposed to
do, according to the spec ("docs/specs/acpi_cpu_hotplug.txt").

The symptom is that the "modern interface negotiation protocol"
described in commit ae340aa3d2:

> +      Use following steps to detect and enable modern CPU hotplug interface:
> +        1. Store 0x0 to the 'CPU selector' register,
> +           attempting to switch to modern mode
> +        2. Store 0x0 to the 'CPU selector' register,
> +           to ensure valid selector value
> +        3. Store 0x0 to the 'Command field' register,
> +        4. Read the 'Command data 2' register.
> +           If read value is 0x0, the modern interface is enabled.
> +           Otherwise legacy or no CPU hotplug interface available

falls apart for the guest: steps 1 and 2 are lost, because they are DWORD
writes; so no switching happens.  Step 3 (a single-byte write) is not
lost, but it has no effect; see the condition in cpu_status_write() in
patch#8.  And step 4 *misleads* the guest into thinking that the switch
worked: the DWORD read is lost again -- it returns zero to the guest
without ever reaching the device model, so the guest never learns the
switch didn't work.

This means that guest behavior centered on the "Command data 2" register
worked *only* in the v5.0.0 release; it got effectively regressed in
v5.1.0.

To make things *even more* complicated, the breakage was (and remains, as
of today) visible with TCG acceleration only.  Commit 5d971f9e67 makes
no difference with KVM acceleration -- the DWORD accesses still work,
despite "valid.max_access_size = 1".

As commit 5d971f9e67 suggests, fix the problem by raising
"valid.max_access_size" to 4 -- the spec now clearly instructs the guest
to perform DWORD accesses to the legacy register block too, for enabling
(and verifying!) the modern block.  In order to keep compatibility for the
device model implementation though, set "impl.max_access_size = 1", so
that wide accesses be split before they reach the legacy read/write
handlers, like they always have been on KVM, and like they were on TCG
before 5d971f9e67 (v5.1.0).

Tested with:

- OVMF IA32 + qemu-system-i386, CPU hotplug/hot-unplug with SMM,
  intermixed with ACPI S3 suspend/resume, using KVM accel
  (regression-test);

- OVMF IA32X64 + qemu-system-x86_64, CPU hotplug/hot-unplug with SMM,
  intermixed with ACPI S3 suspend/resume, using KVM accel
  (regression-test);

- OVMF IA32 + qemu-system-i386, SMM enabled, using TCG accel; verified the
  register block switch and the present/possible CPU counting through the
  modern hotplug interface, during OVMF boot (bugfix test);

- I do not have any testcase (guest payload) for regression-testing CPU
  hotplug through the *legacy* CPU hotplug register block.

97f4effeb6 hw/acpi/aml-build: Only generate cluster node in PPTT when specified
Currently we'll always generate a cluster node no matter user has
specified '-smp clusters=X' or not. Cluster is an optional level
and will participant the building of Linux scheduling domains and
only appears on a few platforms. It's unncessary to always build
it when it cannot reflect the real topology on platforms having no
cluster implementation and to avoid affecting the linux scheduling
domains in the VM. So only generate the cluster topology in ACPI
PPTT when the user has specified it explicitly in -smp.

Tested qemu-system-aarch64 with `-smp 8` and linux 6.1-rc1, without
this patch:
estuary:/sys/devices/system/cpu/cpu0/topology$ cat cluster_*
ff	# cluster_cpus
0-7	# cluster_cpus_list
56	# cluster_id

with this patch:
estuary:/sys/devices/system/cpu/cpu0/topology$ cat cluster_*
ff	# cluster_cpus
0-7	# cluster_cpus_list
36	# cluster_id, with no cluster node kernel will make it to
	  physical package id
