Changing the ACPI table size causes migration to break, and the memory
hotplug work opened our eyes on how horribly we were breaking things in
2.0 already.
The ACPI table size is rounded to the next 4k, which one would think
gives some headroom. In practice this is not the case, because the user
can control the ACPI table size (each CPU adds 97 bytes to the SSDT and
8 to the MADT) and so some "-smp" values will break the 4k boundary and
fail to migrate. Similarly, PCI bridges add ~1870 bytes to the SSDT.
This patch concerns itself with fixing migration from QEMU 2.0. It
computes the payload size of QEMU 2.0 and always uses that one.
The previous patch shrunk the ACPI tables enough that the QEMU 2.0 size
should always be enough; non-AML tables can change depending on the
configuration (especially MADT, SRAT, HPET) but they remain the same
between QEMU 2.0 and 2.1, so we only compute our padding based on the
sizes of the SSDT and DSDT.
Migration from QEMU 1.7 should work for guests that have a number of CPUs
other than 12, 13, 14, 54, 55, 56, 97, 98, 139, 140. It was already
broken from QEMU 1.7 to QEMU 2.0 in the same way, though.
Even with this patch, QEMU 1.7 and 2.0 have two different ideas of
"-M pc-i440fx-2.0" when there are PCI bridges. Igor sent a patch to
adopt the QEMU 1.7 definition. I think distributions should apply
it if they move directly from QEMU 1.7 to 2.1+ without ever packaging
version 2.0.

The ACPI specification says:
The ASL compiler can emit two different AML opcodes for a Package
declaration, either PackageOp or VarPackageOp. For small, fixed-length
packages, the PackageOp is used and this opcode is compatible with ACPI
1.0. A VarPackageOp will be emitted if any of the following conditions
are true:
. The NumElements argument is a TermArg that can only be resolved at
runtime.
. At compile time, NumElements resolves to a constant that is larger than
255.
. The PackageList contains more than 255 initializer elements.
Note: The ability to create variable-sized packages was first introduced
in ACPI 2.0. ACPI 1.0 only allowed fixed-size packages with up to 255 elements.
So the spec seems to say a fixed value up to 255 must always
be used with PackageOp and not VarPackageOp, and some guests
(windows up to win2k8) seem to interpret it like this.
Let's do just this, choosing the encoding depending on
the number of elements.
Fixes 9bcc80cd71
(i386/acpi-build: allow more than 255 elements in CPON).

The build_ssdt() function builds a number of AML objects that are related
to CPU hotplug, and whose IDs form a contiguous sequence of APIC IDs.
(APIC IDs are in fact discontiguous, but this is the traditional
interface: build a contiguous sequence from zero up that covers all
possible APIC IDs.) These objects are:
- a Processor() object for each VCPU,
- a NTFY method, with one branch for each VCPU,
- a CPON package with one element (hotplug status byte) for each VCPU.
The build_ssdt() function currently limits the *count* of processor
objects, and NTFY branches, and CPON elements, in 0xFF (see the assignment
to "acpi_cpus"). This allows for an inclusive APIC ID range of [0..254].
This is incorrect, because the highest APIC ID that we otherwise allow a
VCPU to take is 255.
In order to extend the maximum count to 256, and the traversed APIC ID
range correspondingly to [0..255]:
- the Processor() objects need no change,
- the NTFY method also needs no change,
- the CPON package must be updated, because it is defined with a
DefPackage, and the number of elements in such a package can be at most
255. We pick a DefVarPackage instead.
We replace the Op byte, and the encoding of the number of elements.
Compare:
DefPackage := PackageOp PkgLength NumElements PackageElementList
DefVarPackage := VarPackageOp PkgLength VarNumElements PackageElementList
PackageOp := 0x12
VarPackageOp := 0x13
NumElements := ByteData
VarNumElements := TermArg => Integer
The build_append_int() function implements precisely the following TermArg
encodings (a subset of what the ACPI spec describes):
TermArg := DataObject
DataObject := ComputationalData
ComputationalData := ConstObj | ByteConst | WordConst | DWordConst
directly encoded in the function, with build_append_byte():
ConstObj := ZeroOp | OneOp
ZeroOp := 0x00
OneOp := 0x01
call to build_append_value(..., 1):
ByteConst := BytePrefix ByteData
BytePrefix := 0x0A
ByteData := 0x00 - 0xFF

As reported in
http://article.gmane.org/gmane.comp.emulators.qemu/253987
Mac OSX actually requires describing all occupied slots
in ACPI - even if hotplug isn't enabled.
I didn't expect this so I dropped description of all
non hotpluggable slots from ACPI.

hotplug for pci bridges), PCI cards show up in the "device tree" of OS X
(System Information). E.g., on MountainLion users have:

After commit 99fd437dee, users get:

Ethernet still works, but it's not showing up on the PCI bus, and it
no longer thinks it's plugged in to slot #2, as it used to before the
change.
To fix, append description for all occupied non hotpluggable PCI slots.
One need to be careful when doing this: VGA devices
are now described in SSDT, so we need to drop description from DSDT.
And ISA devices are used in DSDT so drop them from SSDT.

This enables support for device hotplug behind

to be pre-configured on qemu command line.
Design:
- at machine init time, assign "bsel" property to bridges with
hotplug support
- dynamically (At ACPI table read) generate ACPI code to handle
hotplug events for each bridge with "bsel" property
Note: ACPI doesn't support adding or removing bridges by hotplug.
We detect and prevent removal of bridges by hotplug,
unless they were added by hotplug previously
(and so, are not described by ACPI).

This adds C code for generating ACPI tables at runtime,
imported from seabios git tree
commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd
Although ACPI tables come from a system BIOS on real hw,
it makes sense that the ACPI tables are coupled with the
virtual machine, since they have to abstract the x86 machine to
the OS's.
This is widely desired as a way to avoid the churn
and proliferation of QEMU-specific interfaces
associated with ACPI tables in bios code.
Notes:
As BIOS can reprogram devices prior to loading
ACPI tables, we pre-format ACPI tables but defer loading
hardware configuration there until tables are loaded.
The code structure was intentionally kept as close
to the seabios original as possible, to simplify
comparison and making sure we didn't lose anything
in translation.
Minor code duplication results, to help ensure there are no functional
regressions, I think it's better to merge it like this and do more code
changes in follow-up patches.
Cross-version compatibility concerns have been addressed:
ACPI tables are exposed to guest as FW_CFG entries.
When running with -M 1.5 and older, this patch disables ACPI
table generation, and doesn't expose ACPI
tables to guest.
As table content is likely to change over time,
the following measures are taken to simplify
cross-version migration:
- All tables besides the RSDP are packed in a single FW CFG entry.
This entry size is currently 23K. We round it up to 64K
to avoid too much churn there.
- Tables are placed in special ROM blob (not mapped into guest memory)
which is automatically migrated together with the guest, same
as BIOS code.
- Offsets where hardware configuration is loaded in ACPI tables
are also migrated, this is in case future ACPI changes make us
rearrange the tables in memory.
This patch reuses some code from SeaBIOS, which was originally under
LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This
relicensing has been acked by all contributors that had contributed to the
code since the v2->v3 relicense. ACKs approving the v2+ relicensing are
listed below. The list might include ACKs from people not holding
copyright on any parts of the reused code, but it's better to err on the
