Linux and Windows need ACPI SRAT table to make memory hotplug work properly,
however currently QEMU doesn't create SRAT table if numa options aren't present
on CLI.
Which breaks both linux and windows guests in certain conditions:
* Windows: won't enable memory hotplug without SRAT table at all
* Linux: if QEMU is started with initial memory all below 4Gb and no SRAT table
present, guest kernel will use nommu DMA ops, which breaks 32bit hw drivers
when memory is hotplugged and guest tries to use it with that drivers.
Fix above issues by automatically creating a numa node when QEMU is started with
memory hotplug enabled but without '-numa' options on CLI.
(PS: auto-create numa node only for new machine types so not to break migration).
Which would provide SRAT table to guests without explicit -numa options on CLI
and would allow:
* Windows: to enable memory hotplug
* Linux: switch to SWIOTLB DMA ops, to bounce DMA transfers to 32bit allocated
buffers that legacy drivers/hw can handle.

should not be declared here to avoid that anybody is using them in a
wrong way. Since we're also going to poison CONFIG_KVM for common code,
let's move them to kvm_i386.h instead. Most of the dummy definitions
from sysemu/kvm.h are also unused since the code that uses them is
only compiled for CONFIG_KVM (e.g. target/i386/kvm.c), so the unused

When there are more nodes than available memory to put the minimum
allowed memory by node, all the memory is put on the last node.
This is because we put (ram_size / nb_numa_nodes) &
~((1 << mc->numa_mem_align_shift) - 1); on each node, and in this
case the value is 0. This is particularly true with pseries,
as the memory must be aligned to 256MB.
To avoid this problem, this patch uses an error diffusion algorithm [1]
to distribute equally the memory on nodes.
We introduce numa_auto_assign_ram() function in MachineClass
to keep compatibility between machine type versions.
The legacy function is used with pseries-2.9, pc-q35-2.9 and
pc-i440fx-2.9 (and previous), the new one with all others.
Example:
qemu-system-ppc64 -S -nographic -nodefaults -monitor stdio -m 1G -smp 8 \
-numa node -numa node -numa node \
-numa node -numa node -numa node
Before:
(qemu) info numa

node 0 cpus: 0 6

Since 2.7 commit (b2a575a Add optionrom compatible with fw_cfg DMA version)
regressed migration during firmware exection time by
abusing fwcfg.dma_enabled property to decide loading
dma version of option rom AND by mistake disabling DMA
for 2.6 and earlier globally instead of only for option rom.
so 2.6 machine type guest is broken when it already runs
firmware in DMA mode but migrated to qemu-2.7(pc-2.6)
at that time;
a) qemu-2.6:pc2.6 (fwcfg.dma=on,firmware=dma,oprom=ioport)
b) qemu-2.7:pc2.6 (fwcfg.dma=off,firmware=ioport,oprom=ioport)
to: a b
from
a OK FAIL
b OK OK
So we currently have broken forward migration from
qemu-2.6 to qemu-2.[789] that however could be fixed
for 2.10 by re-enabling DMA for 2.[56] machine types
and allowing dma capable option rom only since 2.7.
As result qemu should end up with:
c) qemu-2.10:pc2.6 (fwcfg.dma=on,firmware=dma,oprom=ioport)
to: a b c
from
a OK FAIL OK
b OK OK OK
c OK FAIL OK
where forward migration from qemu-2.6 to qemu-2.10 should
work again leaving only qemu-2.[789]:pc-2.6 broken.

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.

The isa_bus_irqs function initializes ISA bus IRQ array pointer with specified

Previously the ICH9 LPC bridge model did not have its own IRQs but
only IRQ pointer cache. And same GSI were used for ISA bus and other sources
behind the bridge (PCI, SCI). Hence, the pc_q35_init was only possible place to
setup both ISA bus IRQs and the bridge IRQ cache.
As a result, the call of isa_bus_irqs was made from pc_q35_init.
Now the ICH9 LPC bridge has its own output IRQs which are connected to GSI. The

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.

xen_hvm_init() returns -1 without cleaning up on some errors (harmless
long as the caller exit()s on error), dies with hw_error() on others.
hw_error() isn't approprate here. Clean up to exit() on all errors.

Remove the redundant 'alias = NULL' and 'is_default = 0' lines
from older machine-types. pc_*_2_4_machine_options() already
clear those fields, so they don't need to be cleared by
pc_*_2_3_machine_options().
