This series is an attempt to make the compat_props lists from the PC code
reusable by other machine-types. All the compat bits that are on those lists are
not tied to a specific machine-type, but instead to the device code that was
present on a given QEMU version.
The last patch is a proposal to simply eliminate the PC-specific compat props
macros, because we don't really need them today. All compat properties we have
can be on global QEMU-version-specific lists, because PC-specific properties are
not going to affect other machine-types anyway.

They are not used anywhere else, to it is simpler to just keep them
closer to the places where they are used.

The PC_COMPAT_* macros include each other, and the PC_Q35_COMPAT_*
macros _also_ included each other. That caused lots of properties to
appear multiple times on PC_Q35_COMPAT_*.
For example, PC_Q35_COMPAT_1_4 expanded to the following:
PC_Q35_COMPAT_1_4:
|-> PC_COMPAT_1_4:
| |-> PC_COMPAT_1_5:
| | |-> PC_COMPAT_1_6:
| | | |-> PC_COMPAT_1_7:
| | | | |-> PC_COMPAT_2_0:
| | | | | `-> [pc-2.0 vars]
| | | | `-> [pc-1.7 vars]
| | | `-> [pc-1.6 vars]
| | `-> [pc-1.5 vars]
| `-> [pc-1.4 vars]
|-> PC_Q35_COMPAT_1_5:
| |-> PC_COMPAT_1_5:
| | |-> PC_COMPAT_1_6:
| | | |-> PC_COMPAT_1_7:
| | | | |-> PC_COMPAT_2_0:
| | | | | `-> [pc-2.0 vars]
| | | | `-> [pc-1.7 vars]
| | | `-> [pc-1.6 vars]
| | `-> [pc-1.5 vars]
| |-> PC_Q35_COMPAT_1_6:
| | |-> PC_COMPAT_1_6:
| | | |-> PC_COMPAT_1_7:
| | | | |-> PC_COMPAT_2_0:
| | | | | `-> [pc-2.0 vars]
| | | | `-> [pc-1.7 vars]
| | | `-> [pc-1.6 vars]
| | |-> PC_Q35_COMPAT_1_7:
| | | |-> PC_COMPAT_1_7:
| | | | |-> PC_COMPAT_2_0:
| | | | | `-> [pc-2.0 vars]
| | | | `-> [pc-1.7 vars]
| | | |-> PC_Q35_COMPAT_2_0:
| | | | |-> PC_COMPAT_2_0:
| | | | | `-> [pc-2.0 vars]
| | | | `-> [pc-q35-2.0 vars]
| | | `-> [pc-q35-1.7 vars]
| | `-> [pc-q35-1.6 vars]
| `-> [pc-q35-1.5 vars]
`-> [pc-q35-1.4 vars]
In other words, the pc-2.0 variables from PC_COMPAT_2_0 appeared 5 times
inside PC_Q35_COMPAT_1_4.
This makes the following changes:
* Reusable PC_COMPAT_* macros on pc.h have NO nesting;
* Instead of using PC_COMPAT_* directly, now pc_piix.c has its own
PC_I440FX_COMPAT_* macros.
* Machine-type-specific PC_*_COMPAT_* macros on .c files are
nested, and reuse the common PC_COMPAT_* macros.
Thus the expansion of PC_Q35_COMPAT_1_4 becomes:
PC_Q35_COMPAT_1_4:
|-> PC_Q35_COMPAT_1_5:
| |-> PC_Q35_COMPAT_1_6:
| | |-> PC_Q35_COMPAT_1_7:
| | | |-> PC_Q35_COMPAT_2_0:
| | | | |-> PC_COMPAT_2_0:
| | | | | `-> [pc-2.0 vars]
| | | | `-> [pc-q35-2.0 vars]
| | | |-> PC_COMPAT_1_7:
| | | | `-> [pc-1.7 vars]
| | | `-> [pc-q35-1.7 vars]
| | |-> PC_COMPAT_1_6:
| | | `-> [pc-1.6 vars]
| | `-> [pc-q35-1.6 vars]
| |-> PC_COMPAT_1_5:
| | `-> [pc-1.5 vars]
| `-> [pc-q35-1.5 vars]
|-> PC_COMPAT_1_4:
| `-> [pc-1.4 vars]
`-> [pc-q35-1.4 vars]

The QEMU_COMPAT_* macros will contain compat properties that are not
specific to PC, and may be reused by other machine-types.
PC-specific properties were left on the PC_COMPAT_* macros.

All compat properties are only applied if a device of an specific type
is instantiated. There's no need to keep a PC-specific list of compat
properties, as properties for PC-specific devices won't affect other
machine-types anyway.
This patch moves all compat_props properties from PC compat macros, to
QEMU_COMPAT_*.
In case somebody wonders why the nesting was kept on the
machine-type-specific PC_*_COMPAT_* macros instead of making
QEMU_COMPAT_* macros nested. The answer is that making QEMU_COMPAT_*
nested would make it more difficult to migrate the existing machine-type
code to QOM later using class_init reuse. See:
https://github.com/ehabkost/qemu-hacks/commit/9edb1f70fc2bd74131f54a2dfed1e890a5859736
PC_COMPAT_1_3 and older are being left untouched by now, as they still
need some additional cleanup and are unlikely to be reused by new
machine-types anyway.

Only a suggestion: Maybe we can move all the compat props to a new header file,
say include/hw/compat.h so we don't need to modify board.h every time we need a
compat prop? board.h will remain cleaner this way.
Thanks,

So why do we still need 2 sets of hierarchies PC_I440FX_COMPAT_x_y and
PC_Q35_COMPAT_x_y? It seems that QEMU_COMPAT_x_y is enough.
Am I missing something?

A single PC_COMPAT_* hierarchy should be enough after this patch, yes. I
left them there because I was not sure this RFC would be accepted, and
wanted to keep the changes simple.
If people are OK with this patch, I can reorder the changes in this
series and move everything to QEMU_COMPAT_* in fewer steps, without even
creating the new PC_I440FX_COMPAT_* macros.

Just noticed a typo now in this part which was added by me previously.
This should also be "prog_if" instead of "prof_if". Can you also correct
that while changing this or otherwise while merging or should I send a
separate patch with just this change?

I just sent a separate patch for that. I prefer not to change code while
moving it.

The idea is cool, the separation of which properties go to boards.h and
which stay in hw/i386/pc_piix.c is not clear though (PIIX is unlikely to be
wanted somewhere else but virtio is).

As far as I can tell this will break hpet,
because you set it incorrectly for PIIX
#define QEMU_COMPAT_1_7 \
@@ -179,6 +197,16 @@ struct MachineState {
.driver = TYPE_USB_DEVICE,\
.property = "msos-desc",\
.value = "no",\

AFAIK above is appropriate for Q35 but not PIIX.

How was this tested?
I would suggest compiling qemu before and after this
patch. stripped objects should be identical.

More boiler-plate to add with each new machine, yeh.
How about this instead:
#define PC_Q35_COMPAT_2_0 \

{\
.driver = "ICH9-LPC",\
.property = "memory-hotplug-support",\
.value = "off",\

.property = COMPAT_PROP_PCP,\
.value = "off",\
}
static QEMUMachine pc_q35_machine_v2_0 = {

Above are x86 CPUs - why have them in a common header?
There's no chance any machine except PIIX&Q35 needs these.

Here's an example.
If you are using a non x86 target, QEMU 2.0
has no way to select a machine with this
value.
So why expose it?

virtio compat < 2.0 is not useful to non x86 either.

As we talked on the KVM call, the objective is to assign the
compat properties per QEMU version and close to their device.
As a *middle* step we shall put all together in a common file
per version and not per machine type, and then work on a registration
mechanism that will be based on the fact that compat properties
are per device and versioned by QEMU.

Yes but that'll stay on a branch and get merged after 2.1.
Let's keep this patch on that branch there as well.

So global properties are really not so special.
They just need to be specified with <X>.<Y>=<Z> syntax.
Can we just make them properties of a QEMU object?
I would like to make it possible for management to
ask "what's the default value for that property with that
machine type".
Need to add API to make this painless, with not more lines of code
than currently.

I assume this was explained in the v2 commit message, and there was no
bug here, right?

We don't even have an API for asking for class property info (with no
machine-type-specific data) yet. I keep asking if we are going to move
towards some day. But the current plan is unclear to me, and the only
available method today seems to be "just create an object and ask for
its properties" (the same seems to be necessary even for listing the
available property _names_).
There has been some discussion about it at:
http://marc.info/?l=qemu-devel&m=139170340408156
but the conclusion was unclear.
