[Qemu-ppc] [RFC 00/12] QOM'ify remaining CPUs

[Andreas Färber]

Hello,

Based on qom-cpu v4 and object_class_get_list() v2, this series converts
the remaining CPUs to QOM. Their only intersection point is Makefile.target.

TODO: Review LGPLv2.1 text differences (bug in German GNU webpage).
TODO: Check that cpu_model_str is set correctly everywhere.


target-i386:

Eduardo Habkost has already pointed out that it might be better to use
QOM properties for -cpudef in target-i386, so that we use the same code paths
internally as QMP users or machine compatibility code would.

(Sorry if I forget someone.)


target-ppc:

As already discussed with Alex, I didn't manage to split out the QOM PowerPCCPU
into cpu.c from translate.c #including translate_init.c within a reasonable 
time,
so this becomes an exception in Makefile.target in the follow-up series.

The initfn/uninitfn can be simplified in v2 by putting them in powerpc_cpu_info.

target-xtensa:

Xtensa was problematic in that it used declarative definitions for XtensaConfig
whose macros I did not manage to convert to an imperative class_init with
reasonable effort. I therefore resorted to a really ugly memcpy(), better ideas
or follow-up patches welcome!

target-mips:

Note that MIPSCPU conflicts with an in-flight FPU reset fix from Khansa and 
Mentor
and with ASE DSP series by Jia Liu.

Most conversions were pretty straightforward. Pattern was always:
* Add a new cpu-qom.h header to entangle QOM data and cpu.h #defines
* Add a new cpu.c file implement FooCPU, FooCPUClass
* If available, move list of CPU models into FooCPUInfo cpus[] in cpu.c
* Embed CPUFooState as member of FooCPU
* Define ENV_GET_OBJECT(env) macro
* Make cpu-qom.h globally available through cpu.h (for now)
* Move cpu_foo_init() code into foo_cpu_initfn()
* Change cpu_foo_init() to use object_new() with a CPU type
  => Some parts remain that might be moved into initfn in follow-ups.
* Move cpu_foo_reset() code into foo_cpu_reset()
* Let cpu_foo_reset() just call cpu_reset()
* If implemented, change cpu_foo_list_cpu() to get, sort, print GSList of 
FooCPUClass
  => This may change the sometimes arbitrary order in user-visible -cpu ? 
output.
* If any, fix cpu.h vs. cpu-qom.h circular dependency issues through static 
inline helpers
