[Qemu-devel] [RFC qom-cpu v2 0/2] target-sh4: SuperHCPU subclasses

[Andreas Färber]

Hello,

This series introduces SuperH CPU subclasses.
The first conversion to QOM patch had used a declarative approach reusing
sh4_def_t as SuperHCPUInfo. This approach now uses imperative instance_init
functions. To preserve -cpu ? output and case-insensitivity, distinct name
and type name are used, but allowing use of the type name as done for alpha.

TODO: guard against abstract types (may apply to other targets as well)
TODO: move class -> name lookup to cpu.c?

This series in context:
+ qom-cpu cleanups and bugfixes being queued for 1.4
+ CPUState QOM realizefn and initfn RFC for 1.5 / qom-cpu-next
~ SuperHCPU subclasses (this series)
- SH7750 QOM'ification (to be rebased)
- cross-target refactoring of cpu_init() and "realized" behavior (TBD)

Available for testing at:
git://github.com/afaerber/qemu-cpu.git qom-cpu-sh4-classes.v2
https://github.com/afaerber/qemu-cpu/commits/qom-cpu-sh4-classes.v2

Regards,
Andreas

v2:
* Fixed bug in class name comparison, spotted by Igor.
* Refactored name -> ObjectClass mapping into new function.
* Moved realizefn patch into CPUState series, rebased.

v1 -> preview on GitHub:
* Redone, using combination of initfn and class_init instead of SuperHCPUInfo.
* Adopted naming scheme suggested by Eduardo.
* Split out SuperHCPUClass field movements into separate patch.
