NFIT is defined in ACPI 6.0: 5.2.25 NVDIMM Firmware Interface Table (NFIT)
Currently, we only support PMEM mode. Each device has 3 structures:
- SPA structure, defines the PMEM region info
- MEM DEV structure, it has the @handle which is used to associate specified
ACPI NVDIMM device we will introduce in later patch.
Also we can happily ignored the memory device's interleave, the real
nvdimm hardware access is hidden behind host
- DCR structure, it defines vendor ID used to associate specified vendor
nvdimm driver. Since we only implement PMEM mode this time, Command
window and Data window are not needed
The NVDIMM functionality is controlled by the parameter, 'nvdimm', which
is introduced for the machine, there is a example to enable it:
-machine pc,nvdimm -m 8G,maxmem=100G,slots=100 -object \
memory-backend-file,id=mem1,share,mem-path=/tmp/nvdimm1,size=10G -device \
nvdimm,memdev=mem1,id=nv1
It is disabled on default

This patch adds support for split IRQ chip mode. When
KVM_CAP_SPLIT_IRQCHIP is enabled:
1.) The PIC, PIT, and IOAPIC are implemented in userspace while
the LAPIC is implemented by KVM.
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,
which is handled in target-i386/kvm.c and relayed to the software
IOAPIC via ioapic_eoi_broadcast.

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.
