Commit "8156d48 pc: allow raising low memory via max-ram-below-4g
option" causes a regression on xen, because it uses a different
memory split.
This patch initializes max-ram-below-4g to zero and leaves the
initialization to the memory initialization functions. That way
they can pick different default values (max-ram-below-4g is zero
still) or use the user supplied value (max-ram-below-4g is non-zero).
Also skip the whole ram split calculation on Xen. xen_ram_init()
does its own split calculation anyway so it is superfluous, also
this way xen_ram_init can actually see whenever max-ram-below-4g
is zero or not.

For compatibility reasons PC/Q35 will start with legacy
CPU hotplug interface by default but with new CPU hotplug
AML code since 2.7 machine type. That way legacy firmware
that doesn't use QEMU generated ACPI tables will be
able to continue using legacy CPU hotplug interface.
While new machine type, with firmware supporting QEMU
provided ACPI tables, will generate new CPU hotplug AML,
which will switch to new CPU hotplug interface when
guest OS executes its _INI method on ACPI tables
loading.

This patch extends the functionality of the max-ram-below-4g option
to also allow increasing lowmem. Use case: Give as much memory as
possible to legacy non-PAE guests.
While being at it also rework the lowmem calculation logic and add a
longish comment describing how it works and what the compatibility
constrains are.
Note: This is a incompatible change. When setting max-ram-below-4g to
a value larger than 3.5G (or 3G with gigabyte alignment) it has no
effect on older qemu versions: qemu silently ignores it. With the patch
applied it actually has an effect and changes the ram layout. Highly
unlikely to hit in practive though as there is no reason start old qemu
versions that way.

This patch enables migrating vcpu's TSC rate. If KVM on the
destination machine supports TSC scaling, guest programs will
observe a consistent TSC rate across the migration.
If TSC scaling is not supported on the destination machine, the
migration will not be aborted and QEMU on the destination will
not set vcpu's TSC rate to the migrated value.
If vcpu's TSC rate specified by CPU option 'tsc-freq' on the
destination machine is inconsistent with the migrated TSC rate,
the migration will be aborted.
For backwards compatibility, the migration of vcpu's TSC rate is
disabled on pc-*-2.5 and older machine types.

We can have at most one ISA bus. If you try to create another one,
isa_bus_new() complains to stderr and returns null.
isa_bus_new() is called in two contexts, machine's init() and device's
realize() methods. Since complaining to stderr is not proper in the
latter context, convert isa_bus_new() to Error.
Machine's init():
* mips_jazz_init(), called from the init() methods of machines
"magnum" and "pica"
* mips_r4k_init(), the init() method of machine "mips"
* pc_init1() called from the init() methods of non-q35 PC machines
* typhoon_init(), called from clipper_init(), the init() method of
machine "clipper"
These callers always create the first ISA bus, hence isa_bus_new()
can't fail. Simply pass &error_abort.
Device's realize():
* i82378_realize(), of PCI device "i82378"
* ich9_lpc_realize(), of PCI device "ICH9-LPC"
* pci_ebus_realize(), of PCI device "ebus"
* piix3_realize(), of PCI device "pci-piix3", abstract parent of
"PIIX3" and "PIIX3-xen"
* piix4_realize(), of PCI device "PIIX4"
* vt82c686b_realize(), of PCI device "VT82C686B"
Propagate the error. Note that these devices are typically created
only by machine init() methods with qdev_init_nofail() or similar. If
we screwed up and created an ISA bus before that call, we now give up
right away. Before, we'd hobble on, and typically die in
isa_bus_irqs(). Similar if someone finds a way to hot-plug one of
these critters.

1.) The PIC, PIT, and IOAPIC are implemented in userspace while

2.) The software IOAPIC delivers interrupts to the KVM LAPIC via
kvm_set_irq. Interrupt delivery is configured via the MSI routing
table, for which routes are reserved in target-i386/kvm.c then
configured in hw/intc/ioapic.c
3.) KVM delivers IOAPIC EOIs via a new exit KVM_EXIT_IOAPIC_EOI,

In 2012, QEMU had a bug where it exposed QEMU version information to the
guest, meaning a QEMU upgrade would expose different hardware to the
guest OS even if the same machine-type is being used.
The bug was fixed by commit 93bfef4c6e, on
all machines up to pc-1.0. But we kept introducing the same bug on all
newer machines since then. That means we are breaking guest ABI every
time QEMU was upgraded.
Fix this by setting the hw_version on all PC machines, making sure the
hardware won't change when upgrading QEMU.
Note that QEMU_VERSION was "1.0" in QEMU 1.0, but starting on QEMU
1.1.0, it started following the "x.y.0" pattern. We have to follow it,
to make sure we use the right QEMU_VERSION string from each QEMU
release.
The 2.5 machine classes could have hw_version unset, because the default
value for qemu_get_version() is QEMU_VERSION. But I decided to set it
explicitly to QEMU_VERSION so we don't forget to update it to "2.5.0"
after we release 2.5.0 and create a 2.6 machine class.

Currently IGD drivers always need to access PCH by 1f.0. But we
don't want to poke that directly to get ID, and although in real
world different GPU should have different PCH. But actually the
different PCH DIDs likely map to different PCH SKUs. We do the
same thing for the GPU. For PCH, the different SKUs are going to
be all the same silicon design and implementation, just different
features turn on and off with fuses. The SW interfaces should be
consistent across all SKUs in a given family (eg LPT). But just
same features may not be supported.
Most of these different PCH features probably don't matter to the
Gfx driver, but obviously any difference in display port connections
will so it should be fine with any PCH in case of passthrough.
So currently use one PCH version, 0x8c4e, to cover all HSW(Haswell)
scenarios, 0x9cc3 for BDW(Broadwell).

commit fddd179ab9,
"pc: Convert *_MACHINE_OPTIONS macros into functions"
broke the chaining of *_machine_options() functions on

-#define PC_I440FX_2_3_MACHINE_OPTIONS \
- PC_I440FX_2_4_MACHINE_OPTIONS, \
- .alias = NULL, \
- .is_default = 0
+static void pc_i440fx_2_3_machine_options(QEMUMachine *m)

I have replaced PC_I440FX_2_4_MACHINE_OPTIONS with a
pc_i440fx_machine_options() call, instead of calling
pc_i440fx_2_4_machine_options(). This broke the setting of default_machine_opts

Fix this by making pc_i440fx_2_3_machine_options() reuse

This PIIX4 init function has no more reason to receive a pointer to the
FwCfg object. Remove the parameter from the prototype, and update callers.
As a result, the pc_init1() function no longer needs to save the return
value of pc_memory_init() and xen_load_linux(), which makes it more
similar to pc_q35_init().
The return type & value of pc_memory_init() and xen_load_linux() are not
changed themselves; maybe we'll need their return values sometime later.

This patch introduces no observable change, but it allows the callers of
pc_basic_device_init(), ie. pc_init1() and pc_q35_init(), to request (or
not request) the creation of the FDC explicitly.
At the moment both callers pass constant create_fdctrl=true (hence no
observable change).
Assuming a board passes create_fdctrl=false, "floppy" will be NULL on
output, and (beyond the FDC not being created) that NULL will be passed on
to pc_cmos_init(). Luckily, pc_cmos_init() already handles that case.

isapc to follow the same compat+init pattern used by the other
machine-types, allowing us to generate all init function using the same
macro later.

Now that we have a DEFINE_PC_MACHINE helper macro that just requires an
initialization function, it is trivial to convert them to register a QOM
machine class directly, instead of using QEMUMachine.

Define a MACHINE_OPTIONS macro for each PC machine, and move every field
inside the QEMUMachine structs to the macros, except for name, init, and
compat_props.
This also ensures that all MACHINE_OPTIONS inherit the fields from the
next version, so their definitions carry only the changes that exist
between one version and the next one.
Comments about specific cases:
pc-*-2.1:
Existing PC_*_2_1_MACHINE_OPTIONS macros were defined as:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin"
PC_*_2_2_MACHINE_OPTIONS is:
PC_*_2_3_MACHINE_OPTIONS
which is expanded to:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin",
.default_display = "std"
The only difference between 2_1 and 2_2 is .default_display, that's why
we didn't reuse PC_*_2_2_MACHINE_OPTIONS. The good news is that having
multiple initializers for a field is allowed by C99, and the last
initializer overrides the previous ones.
So we can reuse the 2_2 macro in 2_1 and define PC_*_2_1_MACHINE_OPTIONS
as:
PC_*_2_2_MACHINE_OPTIONS,
.default_display = NULL
pc-*-1.7:
PC_*_1_7_MACHINE_OPTIONS was defined as:
PC_*_MACHINE_OPTIONS
PC_*_2_0_MACHINE_OPTIONS is defined as:
PC_*_2_1_MACHINE_OPTIONS
which is expanded to:
PC_*_2_2_MACHINE_OPTIONS,
.default_display = NULL
which is expanded to:
PC_*_2_3_MACHINE_OPTIONS,
.default_display = NULL
which is expanded to:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin",
.default_display = "std",
.default_display = NULL /* overrides the previous line */
So, the only difference between PC_*_1_7_MACHINE_OPTIONS and
PC_*_2_0_MACHINE_OPTIONS is .default_machine_opts (as .default_display
is not explicitly set by PC_*_MACHINE_OPTIONS so it is NULL).
So we can keep the macro reuse pattern and define
PC_*_2_0_MACHINE_OPTIONS as:
PC_*_2_0_MACHINE_OPTIONS,
.default_machine_opts = NULL
pc-*-2.4 (alias and is_default fields):
Set alias and is_default fields inside the 2.4 MACHINE_OPTIONS macro,
and clear it in the 2.3 macro (that reuses the 2.4 macro).
hw_machine:
As all the machines older than v1.0 set hw_version explicitly, we can
safely move the field to the MACHINE_OPTIONS macros without affecting
the other versions that reuse them.
init function:
Some machines had the init function set inside the MACHINE_OPTIONS
macro. Move it to the QEMUMachine declaration, to keep it consistent
with the other machines.

The VGA and vmware-svga rombar compat properties were added by commit
281a26b15b, but only to pc-0.13 and
pc-0.12. This breaks the PC_COMPAT_* nesting pattern we currently
follow.
The new variables will now be inherited by pc-0.11 and older, but
pc-0.11 and pc-0.10 already have PCI.rombar=0 on compat_props, so they
shouldn't be affected at all.

The compat property was added by commit
9dbcca5aa1, and the pc-0.12 and older
machine-types were not changed because virtio-9p-pci was introduced on QEMU
0.13 (commit 9f10751365). The only problem is
that this breaks the PC_COMPAT_* nesting pattern we currently use.
So, move the property to PC_COMPAT_0_13. This make pc-0.12 and older inherit
it, but that shouldn't be an issue as QEMU 0.12 didn't have virtio-9p-pci.

This reverts commit 13704e4c45.
With the Intel microcode update that removed HLE and RTM, there will be
different kinds of Haswell and Broadwell CPUs out there: some that still
have the HLE and RTM features, and some that don't have the HLE and RTM
features. On both cases people may be willing to use the pc-*-2.3
machine-types.
So instead of making the CPU model results confusing by making it depend
on the machine-type, keep HLE and RTM on the existing Haswell and
Broadwell CPU models. The plan is to introduce "Haswell-noTSX" and
"Broadwell-noTSX" CPU models later, for people who have CPUs that don't
have TSX feature available.

Older PC machine types might by accident be backwards live migration compatible,
but with the new vmdesc self-describing blob in our live migration stream we
would break that compatibility.
Also users wouldn't expect massive behaviorial differences when updating to a
new version of QEMU while retaining their old machine type, especially not
potential breakage in tooling around live migration.
So disable vmdesc submission for old PC machine types.
